@-6

after quietly going through his morning routine in the bathroom, eric headed downstairs to find cassie drinking tea and reading email at the kitchen table. she looked up nervously when he walked into the kitchen, but seemed relieved when he smiled and wished her, "good morning, cassie," just like any other day.

eric dug into a bowl of cereal and asked cassie, "will you be ready to go set up the beach after i'm done eating?"

"yeah, that would be great," cassie quickly replied. "i almost forgot that we were doing that today," she nodded absentmindedly.

"would it be okay if we start doing the 'cali' thing as soon as we walk ellie into spring break?" eric watched her expression closely to gauge her reaction.

"sure...sure," her eyes met his for a moment before looking down at the table.

"whatever you want.'

"i just figured that would give you time to get whatever else you needed done," eric added helpfully. "so then you could just be cali the rest of the time and not worry about anything else...if that works for you."

"no, no...that's perfect, actually," cassie nodded.

"great," eric let out a small release of breath. "because i really need cassie's help in setting up spring break and making it awesome for ellie and cali." he smiled.

"well, i hope you're going to enjoy it too," cassie looked at him quizzically.

"i am," eric nodded. "but i really wanted to make it more about those two."

"are you sure?" cassie looked at him earnestly. "i just feel like you put so much work into these things and only look out for what we want all the time."

"i know, but it ends up being awesome doesn't it?" he smiled. "i think it's going to be great. i guess the thing i just want most is for cali to be a good sport and make sure that ellie has an amazing time."

"i can totally do that", she smiled. cassie shut down her laptop and went up to her room to get dressed to go outside while eric finished eating. she had been second guessing herself since she woke up and kind of dreading facing eric this morning, but he was doing such a good job of making it easy for her. he had been the same sweet, caring eric he always was at breakfast, at the same time she knew that he was planning for her to have some quality 'cali' time at spring break later that day.

cassie found she was happy and excited as she got dressed. her anxiety about the effect that her arrangement would have on eric's relationship with her had disappeared, at the same time that her anticipation about letting loose at spring break was building. she was a little nervous about the unknown element of what was coming, but she took some comfort from the fact that ellie would be with her the whole time she was being 'cali' and that it would mean that things couldn't get too wild. it felt like the perfect balance for the first day of their new arrangement and she felt almost giddy with anticipation.

once they'd decorated the beach, cassie and eric headed back to the house for lunch and a quick shower before spring break started. there was no sign of ellie as they fixed lunch and cassie suggested that she go wake ellie up while eric fixed her something to eat and then they could both get ready.

eric was almost finished with his shower when he saw the light in the bathroom change as the door to ellie's room opened. moments later, her face popped in from behind the shower curtain at the far end, taking a flirty look at his wet, naked body as he turned toward her.

"so that's what it looks like when it isn't hard," she whispered through a smile.

"good morning, beautiful," eric smiled. he took a step toward her and leaned over carefully to kiss her without dripping water on her.

"so what's the big mystery?" she asked conspiratorially. "i'm supposed to get dressed to go to the beach, but cassie won't tell me what's going on."

"and neither will i," he teased. "it's a surprise. for you."

"really?" she couldn't repress the look of delight on her face. "is it better than the surprise you gave me last night?" her face got a little flushed at the memory and the wide smile never left her face.

"no hints," eric chided her playfully. "just promise me one thing."

"anything," she whispered enthusiastically, batting her eyelashes flirtatiously.

"i think cassie is going to try out being 'cali' today and i'm curious to see if she is just all talk or really trying to loosen up a bit. so just go along with whatever i do, like it's no big deal, okay?"

"of course!" ellie beamed. "whatever you want." she blew him a kiss and ducked back out, before quickly sticking her head back in. "by the way," she fought an embarrassed smile. "you have the cutest butt!"

"so do you!" he whispered back. "now get out of here. i've got work to do."

cassie waited for ellie to shower and get dressed while eric went ahead to turn everything on and get ready for them to show up. cassie had blindfolded ellie just outside the flap and when she stepped though, eric turned on the old boom box he'd had in his room and pulsing beat of electronic dance music filled the small space as he blew the whistle hanging around his neck and cassie pulled off the blindfold covering ellie's eyes. eric had gotten dressed up in a loud hawaiian shirt, a wide brim straw beach hat, some novelty wayfarer sunglasses from an old halloween costume and had applied white sunscreen to his nose. he was holding a clipboard and looked like a slightly goofy, but hot, lifeguard.

"welcome to spring break 20-20!" eris boomed in his best impersonation of a tv wrestling announcer, extending each word comically long while holding the plastic microphone from a video game they hadn't played in years. "we're down to the last day of the "queen of spring break" contest and i'd like to welcome back our two gorgeous contestants, ellie and cali, for the final day of competition! one of these two lucky ladies will be crowned the "queen of spring break 2020" before the day is through. so get ready for a wild day on the beach as our competition heats up in just a few minutes"

eric set down his microphone and clipboard on the makeshift 'bar' they'd created below the homemade banner announcing "spring break 2020" that was hanging from the pvc frame of the roof.

"so what do you think?," he walked over to where, cassie and ellie were getting stripped down to their bikinis.

"it's amazing you guys!" ellie stopped getting undressed to hug eric and then cassie before undoing and stepping out of her jeans. "i can't believe you guys remembered! it's like all my wishes are coming true!" she looked at eric quickly at the end of the sentence.

eric took his pipe and lighter from on top of the bar and handed it to ellie as cassie folded up their clothes and placed them on the sand behind the bar. ellie and eric had already had a turn by the time cassie stepped over and accepted the pipe. eric handed each of them a red plastic cup with the 'berry popper' concoction and they took a drink to celebrate the start of spring break.

"so you guys ready to do this?" eric held up his clipboard and microphone. they both nodded enthusiastically.

"okay everybody, i want you to join me at center beach for our fabulous limbo competition!" he walked over to where he had rigged up a couple of pvc poles pushed down into the ground with a third for a cross bar, held onto the others with couple of rubber bands. "remember, first one to touch the bar, or fall down trying, loses!"

they each went through the first pass fairly easily and eric slid the bar down a few inches for the next round. cassie did her best, but with the height disadvantage, and ellie's flexibility from gymnastics, it was over pretty quickly as cassie bumped the bar on the fourth round while ellie cleared it with inches to spare.

"so ellie wins our first competition, which means it's cali's turn to face the consequences!" eric turned to the bar and handed cassie a shot of berry drink in a plastic cup as he also handed ellie one of a pair of ping pong paddles, while he kept the other.

"so cali's got to take her medicine and a take the walk of shame down our paddle line everybody!" cassie''s eyes went wide as she took the shot and eric and ellie stood side by side for her to walk past as each of them was allowed to smack her butt playfully with their paddle.

while it only lightly stung as each paddle smacked her butt, cassie felt a thrill as she received each one, tingling with excitement as she felt the paddle make contact with her ass, delivered by the hands of her brother and sister. they all laughed and giggled as they put the paddles back on the bar and prepared for the next event.

"okay folks, it's that magical time when we see which of these contestants sucks, who spits and who swallows!" eric announced with gusto. "let's line up at the bar ladies and remember, you're not allowed to use your hands at any point!"

cassie and ellie shot a quick glance at each other and stepped nervously to the bar, ellie wondering for the first time how far eric would go to push cassie's limits as 'cali'. while cassie calmed herself by remembering that she didn't have to do anything as 'cali' that ellie wouldn't.

eric pulled out four cups and handed each of the girls a drinking straw. "okay ladies, this competition is called, "over the line" as you need to use the straw to suck water from the first cup and transfer it to the second cup." the girls looked down to see a line had been drawn in black marker around the inside of the empty cups about halfway up the side. "first one to get the water level in the second cup over the line wins."

they both took the straws, bent down over the full cups and when eric blew his whistle, they each began sucking mouthfuls of water from the first cup and spitting them back out into the second. cassie quickly realized she could hold the straw in her teeth and allow the water to be released into the second cup more quickly than blowing in through the straw as they had initially been doing. ellie realized what cassie was doing after the first few times, but the advantage cassie had gained was too much and ellie was unable to catch up before cassie filled her cup, "over the line" first.

cassie jumped up and down in celebration as ellie playfully pouted and vowed revenge, but dutifully took her shot penalty and defiantly wiggled her bubble butt as she received a paddling from each of them. eric was already turned on from watching the girls compete, but the paddling idea, that he had added just this morning, was quickly becoming his favorite part.

as they lined up under the banner to hear the next competition announced, ellie looked at cassie with a competitive squint, smiling and vowing, "you're goin' down!"

"okay everyone, it's time for that classic feat of strength, agility and aggression known as 'top wrestling'! let's head over to the pool for the match." they all walked over to the water where eric instructed them to stand in the knee deep water and explained. "the rules are simple ladies. first one to remove the other one's bikini top completely off wins the match. however," he added sternly, "if you tear or damage the other competitors top in any way, or injure the other contestant, you will be disqualified and the other contestant will win." he looked back and forth at each of them to acknowledge that they understood the rules before bringing the whistle to his lips.

while ellie was clearly the more athletic of the two, surging toward cassie as soon as the whistle blew, the longer reach of cassie's arms more than made the match even as they circled for position and pulled at each other's tops. eric had wished that he had stipulated that the competition had to be filmed, as his heart thumped in his chest, watching them grabbing at each other's tops, trying to dislodge each other's tits, while drunkenly giggling and trying not to slip on the plastic liner of the bottom of the pool. a good amount of sand had accumulated on the bottom with use, giving them a little traction, but stepping too quickly was still liable to cause them to slip.

after a couple of drinks and her win in the last round, cassie had begun to fully embrace the role of cali and found it fun to have to compete like a sexy gladiator for eric where the real cassie would have been mortified to participate in something like this. there was no way for ellie to know that eric already had an ability to see her fully topless whenever she wanted and that if ellie was counting on cassie's natural embarrassment to keep her tits from being exposed, then it gave her a hidden advantage. as weird as it felt, she also desperately wanted to expose ellie's big bouncing tits for eric, perhaps to make up for the fact that she had already been forced to expose herself, but also because she thought it might please eric to see ellie topless again too.

ellie did think that cassie's sense of propriety would make up for her advantage in physical reach as her plan was to try and expose cassie's tits by dislodging them from her top and then gain the upper hand while cassie tried to cover her tits and fix her top. for her part, ellie didn't care if her own tits fell out along the way, as eric had seen them plenty already. she liked to have eric look at her boobs, so having them hanging out while he watched them wrestle wouldn't be a disadvantage to her.

ellie ducked in under callie's reach and wrapped her up around her waist, sending them both tipping over into the water. ellie reached up as the tumbled and pulled cassie's top up toward her chin to make her tits come loose as they fell. cassie landed on her back, but quickly rolled over to get a hold of the back strap of ellie's top. cassie held on as ellie squirmed around, until she had caused the clasp on ellie's top to open.

ellie felt her top come loose and knew her tits were jiggling around while her top was dangling, held in place by her one hand against her chest as she tried to get around to the strings on cassie's top. ellie was sure cassie would now be distracted trying to get her boobs covered. as ellie stood up though, cassie had both hands free, seemingly oblivious to her firm tits and flushed pink nipples being exposed by her dislodged top, and before ellie knew it, cassie had snatched ellie's loose top out of her hand and was holding it aloft as a prize, even as she jumped around and tried to get her own boobs back in her top.

ellie was shocked and looked over at eric who was watching the scene with delight. ellie stood there, topless in the bright lights, and he had gotten a good look at cassie's tits jiggling freely about, both during, and just after, the match. ellie looked up ruefully at cassie dancing, but giggled herself when cassie playfully lifted her top out of her reach when ellie tried to grab it. cassie made ellie jump up and down a few times, before ellie finally pulled cassie's top up again, causing her to bring her hands down to cover herself. the girls stood giggling in the water as they fixed their tops, and covered their tits, before ellie came out to drink her shot and provocatively accept her paddling. as cassie paused to towel off her face and hair for a moment, ellie playfully reached out to squeeze the head of eric's obviously hard dick through his trunks.

"enjoying the show?" she asked saucily as eric nodded with a huge smile.

cassie smoothed her hair back with her fingers and smiled to herself as she reveled in how her new sense of liberation had allowed her to beat ellie. she found herself enjoying the competition, and worked up, knowing that eric was controlling each of these events, in order to give her an opportunity to get a little wild, at the same time he was fulfilling ellie's wish. it was clever of him to include the paddling and even watching ellie get paddled had excited her as she imagined that she looked just as submissive in accepting her own penalty. between the drinks and the weed, she felt buzzed, happy and turned on as she waited for eric to start the next event.

"as always, no spring break would be complete without the annual "wet t shirt contest"!" eric announced. "if each of the contestants would come forward to accept their shirts..." eric held up two plain white t shirts that he had brought out from behind the bar and handed one to each of them. ellie pulled her t shirt on and then reached up to undo her top underneath to pull it out from under the shirt and set it on the bar.

seeing ellie do it first, cassie followed suit, undoing the ties on her bikini and slipping it out under her shirt. as the loser of the last event, ellie had to go first as eric took a pitcher of water from the lagoon and poured it over ellie's shirt, soaking it and making it nearly see through as it clung to her bare boobs underneath. eric announced her first round would be for thirty seconds and switched the music to a slow grinding club song.

ellie began dancing and putting on a show, her tits clearly visible beneath the thin, wet fabric of the t shirt, her puffy areolas and hard nipples defined by the way it clung to her skin. ellie rocked her hips and moved her butt in a lasciviously delicious grind to the trance-like beat of the music. even cassie was transfixed by ellie's sensuous curves and the undulating rhythm that she could mirror perfectly with her body, as she made the effect of the already sexy song even more heightened by how she moved.

it was cassie's turn and as the warm water was poured down her shirt, she knew that the darker pink of her own nipples would be even more visible than ellie's were now, that her shirt was wet too. as eric restarted the music, cassie did her best to imitate ellie's dance moves and even without ellie's years of dance training, did an admirable job of making the most of her own long body and perfect ass as she slithered in time with the music and tried to let herself go to the effect of the alcohol, the music and the fact that she knew she was dancing as 'cali' for eric's pleasure, with little actual chance of winning.

as they moved to the final round, ellie declined the option of taking another dousing of water on her shirt from eric, but as soon as the music started, she turned her back to eric and cassie to seductively peel the wet t shirt up off of her body and fling it onto the sand. turning around she held her hands over her breasts and danced seductively for a moment before pulling her hands away and allowing her tits to show freely as she made the most of her ability to grind and jiggle to the music for maximum effect. turning away from them, she ran her hand up along the edges of her bikini bottom, lifting the fabric to expose her full, smooth butt, as if she were wearing a thong, before using the slow grinding beat of the chorus to maximum effect as her now bare ass rocked and twirled in slow seductive patterns, until the thirty seconds was up.

ellie turned around, crossed her arms across her voluptuous tits, cocked her hip and raised her eyebrow with a devilish grin to taunt cassie before her turn. if eric could have pictured a busty tinkerbell, topless in a red bikini bottom, he imagined she'd look just like ellie did now.

setting her chin and squinting at ellie, cassie also refused the option to get another pitcher of water and as the music started, she also turned to give them a slow strip of the wet t shirt coming up over the length of her long topless back. without the full complement of ellie's dance moves, cassie added some teasing elements of looking back over her shoulder, and naughtily covering her mouth like a vintage pin up girl, before turning around to dance with her hands over her bare breasts. using her hands to create a series of 'peek a boo' moments where her tits were visible for only a second at a time, mixed in with winking, mock-scolding at eric's and ellie's naughtiness for looking at her topless, and a final demure flush of embarrassment as she fully revealed her tits, cassie made the most of her more reserved nature to tease out as much effect as she could from stripping to her bottoms in front of eric.

As the music stopped, they both stood waiting, arms crossed across their chests, while Eric pretended to consult with some judges before declaring Ellie the winner of the wet t shirt contest. Ellie stopped covering her breasts to dance triumphantly, waving her hands around as shook her butt and taunted Cassie in her moment of victory. Cassie kept one arm crossed over her bare boobs as she took the penalty shot and leaned against the bar to extend her butt to receive her paddling from each of them. Eric's was still the same playful smack he had used previously, but Ellie was obviously a little more drunk than the last time, and flush with victory, she put an extra little zing on her paddle. It only stung Cassie's butt a little, but she found it excited her, at the same time it left her burning with a sense of rivalry and eager to turn the tables on Ellie at the next opportunity.

Eric announced that the contestants wouldn't need their tops for the next part of the competition, or for the customary refreshment break, as they were now about to enjoy traditional, "Spring Break Body shots!"

As the loser of the last event, Cassie was made to lie back on the sand as Eric poured a shot of 'Brother Pucker' into her navel and making her remove her arms from covering her breasts, rubbed a little of the alcohol on one puffy areola and sprinkled some sugar and then rubbed a little lemon juice on the other. Cassie's nipples were achingly hard just from being exposed to her brother like this, but feeling him rub the liquid on each hard nipple, caused an intense tightening of the skin and raised goose bumps of excitement on each nipple, as well as along her arms. Eric bent over to suck the alcohol from her navel, sucked the lemon juice from her first nipple and then the sugar from the other one.

Cassie's stomach fluttered as she felt Eric sucking at her navel, just inches from where her throbbing pussy was covered in a thin layer of fabric, but her breath hitched as his lips closed over the lemon juice coated nipple and she felt his warm mouth tug at her hard nipple as he sucked the stinging juice from her skin. When he sucked the sprinkled sugar from her other nipple, she was tempted to reach up and hold the back of his head to extend the sensation after how cheated she felt, when the attention he had given her first nipple had ended so quickly.

As Eric finished, Cassie began to get up, but Eric gently pushed her shoulders back on the sand as he poured more of the drink into her navel and prepared her nipples as he had before. He looked over at Ellie kneeling on the other side of Cassie and tilted his head indicating that it was here turn. Ellie looked a little shocked, but she smiled and nodded at Eric, turned to look at Cassie with a helpless look of excitement, before bending over to suck up the alcohol from her sister's navel. If Cassie had felt exposed and titillated by having Eric's mouth on her body, she felt an intense wave of erotic shame at how much she enjoyed the sensation of feeling Ellie's soft, full lips lapping up the liquid from her stomach.

There was something obscenely erotic about looking down to see Ellie's beautiful face, and pink lips, taking her puffy nipple into her mouth, even as Ellie's own bare nipples were brushing against the soft skin of Cassie's stomach, and their breasts were nuzzled against one another as Ellie leaned across her. Ellie looked up briefly as she lifted her mouth from Cassie's first nipple, and caught her sister's wide-eyed expression, as she leaned over to suck the sugar from the puffy peak of her other tit. Cassie couldn't tell if time had simply slowed in her mind, or if Ellie had lingered for a few extra seconds on her second nipple, but as Ellie finally lifted her lips with a blushing sidelong glance into sister's eyes, Cassie felt a release of wetness in her pussy that was as intense as anything she'd ever felt.

Cassie stood up and Ellie took her place on the sand, watching Eric as he made the preparations on her stomach and nipples. It was so strange for Cassie to watch her sister, lying topless like that in broad daylight and see Eric touching her body so casually. As Eric touched his mouth to Ellie's stomach, Cassie watched her sister capture her lower lip between her teeth, and her eyes close, in the moment of feeling his lips upon her skin. As his mouth went from one nipple to the other, Ellie's mouth opened and almost closed again in the rapture of sensation. If Cassie had wanted to get revenge for the hard smack Ellie had given her with the paddle, remembering the lingering suck that Ellie had given her second nipple, suddenly made her also want exact a different kind of payback too.

As Eric prepared Ellie for the second body shot, Ellie's eyes flickered over to Cassie standing above them, hands on her hips and breasts openly exposed, her nipples still fully erect despite the pulsating heat of the lights. Ellie couldn't believe that Cassie no longer seemed to worry about concealing her breasts, but perhaps it was because all of Eric's attention had been on Ellie over the last few minutes and the two of them had seen her topless for the time while she was lying there for her own shots. As Eric finished his preparation, Ellie's eyes looked up to meet Cassie's and a thrill went through her, feeling a sense of anticipation that she hadn't expected.

Cassie knelt topless beside Ellie's waist and leaned over, holding her hair back to drink the alcohol from her sister's stomach. Remembering the feel of Ellie's lips on her own skin, Cassie brought her tongue down to slurp up from the bottom edge of Ellie's navel and had her own soft lips come together to create a small moment of suction in that same place when she finished. She felt Ellie's lower stomach flutter in reaction. As Cassie moved her face up above Ellie's full, luscious boobs, she drank in every detail of how the goosebumps were still rising on the pale pink skin of her puffy areolas. Cassie's eyes slid over to meet Ellie's and she saw Ellie's lips part in anticipation, as Cassie's lips hovered over her nipple.

Cassie took her sister's swollen pink nipple into her mouth and tasted the tart lemon juice that coated her skin. Cassie pulled gently halfway to the tip before lowering her mouth for another suck at it, brushing Ellie's nipple lightly with her tongue, before she gave it a good suck all the way to the tip of her hard nipple, finishing with a light pinch between her firm lips. Eric would have no way to see her tongue on Ellie's nipple, but Cassie heard a small gasp escape Ellie's lips as the tip of her tongue had touched her sister so intimately.

As Cassie took her sister's second nipple into her mouth, she swirled the tip of her tongue completely around the puffy mound before she sucked slowly to the tip of her nipple. As she finished, her eyes darted over to Ellie's face to see that she had turned and was looking down to watch every moment of Cassie's mouth upon her body. Ellie's eyes lifted up to meet her Cassie's, as her sister's lips still held the last nub of her nipple, and it felt like an electric charge passed between them.

Cassie stood up and covered her breasts with her arms as she waited for Eric to help Ellie up. Once on her feet, Ellie looked over to Cassie and asked, "Go rinse off really quick?" Cassie nodded and they both walked over to the water to step in and dip down to rinse the alcohol, sugar and lemon juice from their bodies. Neither spoke, but each took quick glances at the other reaching up to rinse their still hard nipples with their fingers, before both covered themselves with their arms to head back to where Eric waited.

"Alright everyone, I hoped you enjoyed our refreshment break before we head into the finale three events of the competition. For our next event, contestants will be using their hand/eye coordination and their gorgeous tits to score a victory in what we like to call the 'Hand Bra Grape Catch'!" Eric pulled out a cup filled with grapes and explained. "I will be tossing five grapes to each contestant, who will be holding their breasts in their hands and trying to catch as many as they can. Remember, the grapes must be caught and held between your breasts in order to count!"

As the loser of the last event, Cassie had to go first. She held her tits in each hand, as Eric tossed a grape into a high arc, and she tried to 'catch' it, using only her cleavage, by pressing her boobs together and trapping it as it hit her body. As the first grape bounced off her breastbone to land on the sand, she tried not to think about how humiliated she would be if anyone saw her doing something like this, other than Eric and Ellie. As she missed the second and third, she wondered if Eric was enjoying watching her degrade herself like this , with a handful of boob in each hand and waiting, like a dog begging for a treat, as he tossed the grapes to her. She looked over to him and saw him smiling at the sight of her, but if there was any malice in his face, she couldn't see it. It looked like he was enjoying seeing her topless and covered only by her hands, caught up in his plan and surrendering to his request. It gave her a brief flash of embarrassment to realize how far she'd allowed herself to go. She tried her best on the last two, but ultimately failed to catch either one.

Ellie stepped in to take her place, her large boobs barely contained in each hand. Ellie had a low center of gravity that she enhanced with her strong legs and a good stance, maneuvering confidently around under the flight of each grape. When she caught the third grape successfully, she held it for a second to show them both the pale green fruit lodged in her cleavage before she let it fall to the sand and did another topless victory dance, as she had now regained the lead.

Cassie took a moment to put her top back on with her back to Eric as Ellie grabbed her own top, but stood talking to Eric the whole time she was putting it back on. Cassie turned back to face them and took the shot that Eric handed her, before leaning over obediently, bracing her hands against the bar as Eric delivered his paddle to her bottom. With how drunk she felt, she barely felt any discomfort from the light smack. Ellie made an elaborate wind up and seemed to take extra delight in giving a tart little smack to Cassie's butt. Cassie's instincts for sisterly rivalry wanted revenge, but part of her also savored that Eric was seeing her humiliated like that.

"Okay everybody, with only two events left, Ellie has a one point lead over Cali and can win it all if she takes this next event!" Let's head down to the water for the world famous Bikini Swap!" The girls followed him down to the edge of the lagoon.

"Okay when I blow the whistle, you'll both head into the water and take off your bikini, handing it to the other contestant before putting on theirs. The first one to emerge wearing the other's bikini is the winner!" He looked at the two of them smiling. "Okay, is everybody ready?"

He blew the whistle and both of them splashed into the water and began taking off their bikinis. With a single clasp on her top, Ellie had her top off and slipped off her bottoms before Cassie had even finished undoing both ties to her top, but Ellie was left waiting for Cassie to slip off her bottoms before they could trade.

Eric watched with delight as he saw his sisters sitting naked in the water even if they were turned away from him. As they swapped bikinis, Ellie, surprised Cassie by standing up to slip on the bottoms, giving Eric a wonderful view of her naked butt and wet body as she stood in the knee deep water. Cassie squirmed around, sliding the bottoms on, while still sitting in the water, but even though Ellie had a head start putting on the top, Cassie only had to clasp hers around her waist, spin it around, pull it up and cover her tits before she was able to step from the water victorious.

Ellie was visibly frustrated as she stood up and stopped trying to put on Cassie's top. She stepped out of the water, pulling the untied top off and throwing it playfully at Cassie. Ellie stood there, openly topless in front of Eric, waiting for Cassie to do the same.

Cassie looked over at Eric and tilted her head pointedly. "Ummm...a little privacy, please?"

"Oh...yeah," Eric blushed and turned his back to allow them to strip down and get dressed in their own swimsuits.

Once they had gotten dressed, they returned to the bar where Ellie took her penalty shot, placed her hands against the bar, and tilted her butt up seductively to receive her paddling. Eric delivered his paddle as before, but Cassie put a little extra into to match Ellie's last couple of strokes on her own behind. Ellie let out a little gasp when the paddle smacked her bottom, but she was smiling with the tip of her tongue poking from between her teeth as she looked back at Cassie.

"And now for our final event to decide our winner," Eric announced. "This event will measure your ability to set the high mark, in all that you do, in a little event we call, 'Bite Marks'." He reached behind the bar to pull out a cucumber. "The object is simple," he looked at both of them in turn. You slide it in your mouth and the one who leave the bite mark farthest from the tip wins." He handed it to Ellie. As the loser of the last event, she had to go first.

Ellie gave a lasciviously drunken look at Eric as she took the cucumber from him and examined both ends. Taking the narrower tip first, she slid it back into her mouth and opening her jaw as wide as she could, pushed it as deep as she could before biting the skin, just enough to leave an indentation in the surface. She slid it back out of her mouth and held it up to see how much of its length she had fit into her mouth. She looked over at Cassie with a smug grin before glancing over to Eric to see how he had reacted to her result.

Ellie was a little miffed to find Eric already focused on Cassie preparing to take the cucumber into her mouth in the same way. She looked over as Cassie began to insert it into her mouth and watched her struggle to push it as deeply as she could. Fighting the urge to gag as it reached the back part of her mouth, Cassie left a bite mark before pulling it from her mouth.

Cassie handed the cucumber to Eric, but couldn't meet his eyes as she did. Eric held the cucumber up and rolled it slowly in his hands before shaking his head. "I can't believe it," he shrugged. "We've got a tie. If any of the marks are deeper, top or bottom, I can't see it enough to tell a difference." He handed the cucumber to Ellie who rolled it over herself in frustration.

"So then what's the tie-breaker?" Ellie looked up at him.

Eric shrugged. "That was the tie-breaker. I thought with seven events, there was no way we'd have a tie. I don't have any more events," he seemed apologetic.

"But we can't end it in a tie!" Ellie looked at Cassie, who nodded drunkenly in agreement.

"I don't know what else we can do." Eric looked back and forth between them.

Ellie crossed her arms in a huff before a look came over her face. "I do!" She looked from Eric to Cassie. "Let's forget the cucumber and see who wins on the real thing." She nodded declaratively.

"What real thing?" Cassie asked, confused.

"His thing!" Ellie pointed at Eric's hard cock poking up in his shorts.

"Uhhh...nobody is leaving bite marks in my 'thing'," Eric looked at them nervously.

"Not bite marks," Ellie shook her head. "How much we can fit in our mouth!"

"But how would we even know who won if it was that close again?" Cassie felt her heart beating in her chest. Even as drunk as she was, she felt a mixture of excitement and panic when she pictured doing what Ellie described.

"We could make it a photo finish," Ellie raised a single finger in the air. "We take a picture from the same angle and compare them to see who got more."

"Ellie, we can't really be talking about sucking our...about sucking Eric's dick...are we?" Cassie couldn't believe that Ellie would go through with it, once she realized what she was saying.

"No!" Ellie frowned at her, obviously drunk. "We don't have to actually 'suck' it. Just stick it in our mouth long enough to take a picture." She slurred a little at the end. "There's no way this is ending in a tie." She looked competitively at Cassie and smiled. "It's my Spring Break and there can only be one queen, bitch!" She smiled triumphantly.

Cassie wanted to beat Ellie so badly in that moment that she was actually drunk enough to do it. She looked at her sister's smug look and considered her options for a moment through the cloud of alcohol they'd both consumed. "Okay," she said at last. "You lost the last event so you still have to go first."

Ellie gave a squeal of delight and started bouncing and clapping as she turned to Eric. "Okay, big boy. For our next event....we're gonna need your phone...and your dick!" She dropped to her knees and looked up at him expectantly.

Eric looked over at Cassie who shrugged and stood, arms crossed, watching. He retrieved his phone from the bar and unlocked it to open the camera. He could see the last picture he took in a small window off to one side and it was Cassie topless in the bright light of the flash.

"Okay," Ellie directed him. "Hold the camera here and get ready to take the picture when I stop, okay?" She looked up to see if he was ready and looked at his shorts for his dick to appear.

Eric shrugged and lowered the waistband of his shorts over his fully erect cock. He pushed it down to keep it level and positioned his camera to one side about ten inches away. Ellie looked at his dick, the camera and then up at his face. She gave a small wink to Eric and opened her mouth to slide it over her brother's fully engorged dick. Wiggling her head a little side to side, she found the spot where she could take as much as she thought she could manage, before closing her lips around his shaft, to cover as much as she could. Eric took a picture and looked at it to check as Ellie slid her mouth off of his dick.

Eric turned the camera to Ellie to show her the photo and make sure she was happy with how it showcased how much of his dick she could fit in her mouth. Ellie smiled at the result and stood up to let Cassie take her place.

Cassie had been watching in heart-pounding fascination, still unable to believe that Ellie had actually gone through with it. She had watched Eric pull his hard dick from his shorts and allowed herself to fully stare at it while all attention was on Ellie.

Watching Ellie take Eric's dick into her mouth was completely unreal, at the same time it was also the most submissive thing she'd ever seen anyone do for another person. Like the woman in the movie the night before, she marveled at Ellie's willingness to let a man see her so vulnerably, and allow her picture to be taken in such a degrading pose. Letting Eric photograph her topless in the car the night before seemed tame now in comparison.

As drunk as she was, she remembered the terms of the deal where she wouldn't have to do anything that Ellie wasn't also willing to do, but she had also stipulated that Cali wouldn't have to honor any request from Eric to have actual sex with him. Except this wasn't exactly 'sex' and it was Ellie who had requested she do it. If Ellie was willing to take her brother's dick into her mouth, how could 'Cali' refuse?

Cassie stepped over to Eric on rubbery legs and slid down to her knees in the sand. She looked up at Eric who seemed to be simply staring at her in shock behind the dark sunglasses that didn't allow her to see his eyes. In the crazy getup maybe she could pretend that it was someone else, and that the first dick that she would ever have in her mouth, didn't actually belong to her brother. But yet they all knew, just as the throbbing wetness in her pussy did, that this was Eric's cock just inches from her mouth.

Looking at it, as Eric moved his phone into place, to capture the image of the first time she let a man insert his penis into her mouth, she was mesmerized by how big and weirdly muscular his cock looked up close. She could see the bulging structure of the shaft and the slight flare of the head as it tapered to a rounded tip. Her eyes looked up to Eric as she tried to find the momentum to close her eyes and take him into her mouth. Like someone who has climbed to the top of the high dive for the first time and looks down into the water that now looks much further away than it seemed like it would, when they'd looked at the structure from the ground.

"And if I don't do it?", she looked up at Eric who had his dick positioned an inch or so from her lips.

"Then you'd forfeit and Ellie would be queen of Spring Break," Eric cautioned her.

Ellie put her hands on Eric's hips, lowered her eyes and nodded, before slowly rising to her feet and facing Ellie. "You win," she said softly.

Ellie gave a loud whoop and raised her fist in triumph before she started dancing around to the music that continued to blare from the boombox. Eric reached behind the bar to produce a chrome plastic tiara that Cassie had found in a box of old toys in the garage.

"Ladies and gentlemen," Eric announced. "Let's hear it for Ellie, the queen of Spring Break 2020." They all clapped and cheered, even Ellie.

"Due to a forfeit on Cali's part, she will have to pay a more severe penalty than a simple loss." He handed Cassie the penalty shot which she quickly downed. "As a penalty for forfeiting a tiebreaker, Cassie will also have to submit to receiving ten lashes from the winner and the Queen has the option to make the loser take them on her bare behind," he paused, "as well as the right to deliver them with her hand, rather than the paddle."

Ellie burst out giggling when Eric delivered the proclamation. She jumped up and down clapping and then teasingly put a single finger to her lips as she decided Cassie's fate.

"I think I'll deliver the spanking to her bare bottom," Ellie decreed regally, "with my bare hands."

Ellie nodded in defeat and stepped over to the bar where she placed her hands on the edge and extended her body back to offer her behind to Ellie. Ellie stepped over and delicately lowered Cassie's bikini bottoms until her ass cheeks were bared. Ellie possessively rested her small hand for a moment on the smooth skin of Cassie's pale, bare ass, before pulling back it back and delivering the first slap. Ellie winced as she felt the sting of Cassie's hand and hung her head behind her hair to conceal the way she bit her lower lip in pleasure.

After so much drinking, Cassie wasn't bothered by any pain from the spanking. Instead she was wishing she could see herself like Eric did at the moment, bent over with her ass exposed, her younger sister spanking her and allowing her bare hand to rest on the flushed pink cheeks of her ass between delivering each slap. While a part of her wanted Eric to spank her instead, she knew deep down that submitting to Ellie like this was much more humiliating after the rivalry they'd shared growing up. The fact that Eric had engineered this moment, and was watching her being degraded like this, was so delicious that she almost wished she had submitted to taking his dick in her mouth when she had the chance. Except that she wouldn't have been able to experience the shame of this moment if she had.

When it was over, Cassie pulled her bottoms up over her pink ass cheeks and turned to Ellie to hug her and congratulate her on her victory. Ellie clung to Cassie and whispered in her ear, "Thank you for doing this...and letting me win. I hope I didn't spank you too hard."

"No, it was just perfect, El. I'm glad you got to have fun on Spring Break." Cassie whispered back into her sister's ear.

"I'm having so much fun, Cass..." she laughed. "I mean 'Cali'." She pulled back to look her sister in the eyes. "Don't get me wrong. I love my sister to death..." she declared before leaning in to put her mouth right up against Cassie's ear, whispering "But she'd never suck my tits like that!"

Ellie pulled back and covered her mouth in mock-surprise for a moment, before they both burst out laughing and began dancing their asses off to the pulsing techno remix coming from the boom box.

It was Eric's turn to clean up after dinner as the girls had cooked. As much as Eric had hoped to get a few minutes alone with Ellie upstairs, he had gone up to shower by himself while they cooked and couldn't resist taking a minute to release a load of cum before his shower. Eric had pulled up the pictures on his phone, of Cassie topless in the car, and Ellie with his dick in her mouth, to view while he stroked his twitching cock. He was shooting a thick puddle of hot cum into his palm almost immediately.

Thinking he might not get a chance to be with Ellie right away, and knowing that he couldn't hold back much longer after having spent the afternoon watching the girls expose themselves, suck each other's tits and let him touch and suck on their bodies like he had, Eric didn't feel guilty about taking a minute to gain some relief.

Having Ellie kneel to take his hard dick in her mouth for a picture, while Cassie watched, was just the icing that put him over the top. He was sure that he would be fantasizing about all of the memories of that day for the rest of his life.

Hanging out in the living room with Cassie after dinner, Ellie and Eric took every chance they could when their sister left the room, to sneak a quick kiss, flash, or grope of each other's bodies while she was out of sight. As difficult as it was to wait for an opportunity to be with each other alone, there was a certain fun about sharing their secret intimacy in tiny stolen moments that heightened their anticipation for a more satisfying release.

When Cassie had decided to turn in, Ellie went upstairs with her, and Eric followed, just a few minutes later. Thinking he would need to creep through to Ellie's room, he locked his own door, and prepared to head through their shared bathroom, when he heard a noise from his bed. Looking over, it was obvious there was someone under the covers, so he peeled them back to find a grinning Ellie, completely naked, except for her tiara.

"Sorry to show up uninvited like this," she smiled playfully, rising up on her elbows as she watched Eric strip off his clothes. "I was just wondering something and I couldn't wait until morning to ask you."

"Oh yeah," Eric raised his eyebrows in curiosity. "What was that?"

"Well, I was wondering if you'd ever had a chance to titty-fuck a queen before...and if you hadn't..."

Whatever she had intended to say next was smothered by Eric's kiss, as his long, naked body slid up onto hers.

Eric came downstairs the following morning to find Cassie sitting alone at the kitchen table, looking out through the window at the falling snow, and sipping her tea.

"Hey, good morning Cassie," he said softly, so as not to alarm her.

"Hi Eric...good morning." She watched him move around the kitchen, making coffee and fixing a bowl of cereal.

"How are you feeling?" Eric sat down, over and across from her, in their usual spots.

Cassie gave a sheepish grin and tilted her head. "A little hung over I guess." She sipped some more tea.

"Sorry about that," Eric made a face of awkward guilt. "Guess the format of Spring Break might have encouraged a little too much drinking on the part of the contestants."

"Among other things," Cassie rolled her eyes and blushed.

Eric laughed mid-mouthful and milk actually came up, out of his nose. He stood up quickly and grabbed a paper towel from the dispenser under the cupboard. "Oh man, I hate that." He kept trying to blow his nose. "I think I have a little piece of cornflake still stuck up there." He contorted his face uncomfortably and made a noise telling Cassie that he was trying to clear his nasal passages through his mouth. "Ugh, I haven't done that since I was a kid." He grinned sheepishly. "It still sucks." He laughed a little.

Cassie felt all the tension go out of her, watching Eric work through the boyish reaction and giggled herself at the image of the milk shooting from his nose a moment earlier. "I'm sorry Eric." She giggled even more. "It just looked so funny when it happened."

"Glad I could be here to entertain you, then," he grimaced as he wiped at his nose again.

"Seems only fair," she teased him. "I guess Cali and Ellie put on quite a show for you at Spring Break."

He nodded, smiling, even as he blew his nose. "Auughh. Finally got it!" He breathed tentatively and then took a drink of coffee. "Wow, that sucked."

"Speaking of which," Cassie couldn't help herself, surprised to be amused about bringing up an uncomfortable subject. "Just wanted to make sure you didn't think I broke our agreement yesterday."

"What?" Eric looked up, a little confused.

"When...Cali forfeited." She reminded him. "Even though Ellie still did the tiebreaker?"

"Oh....no, we're good," Eric went back to eating his cereal.

"I guess I was a little worried that we never defined where the 'sex' line was," Cassie sounded more serious than she had intended.

"I just figured that it meant, you know, like...actual 'sex'," Eric seemed a little embarrassed and kept looking down at his cereal.

"Sorry, I...I guess Cali just wasn't ready for something like that." Cassie said softly.

"It's cool." Eric shrugged. "I didn't expect anything like that to happen." He chuckled. "You know how competitive Ellie gets." They both giggled nervously. "I was probably more surprised than you were. She was so drunk." He shook his head and toyed with the remaining flakes of cereal in his bowl.

Cassie let out a smooth controlled breath before taking another sip of her tea. "Well, I think you handled it just right," she praised him. "I loved how you changed the penalty for a forfeit, by the way."

Eric took a drink of his coffee and looked over with a beaming smile. "I thought you might like that."

"I can't imagine how it looked," Cassie smiled, blushed and rolled her eyes before looking down to the teacup as she sipped. Something about the way she said it made Eric think that she had imagined it, plenty.

"It looked amazing," Eric felt his cock pushing up against his flannel pajama pants under the table. "You have to admit that Cali has a perfect ass. Like lingerie model perfect.' He watched Cassie blush. "So seeing her like that was just...", Eric tried to keep himself from getting too carried away. "Cali was a really good sport about everything. I appreciated how much effort she put into making sure Ellie enjoyed her Spring Break. I just hope she enjoyed it and had fun too."

Cassie nodded without looking over at him. "Oh, I'm sure she did." Cassie toyed with her teacup. "I think it was just what she needed."

"So you think it was a good first day?" Eric sounded positive and hopeful.

"I thought it was more than I expected...but in a good way." She looked up at Eric at last. "I think the part that I was worried about most, was this." She waved her hand between the two of them. "Like, could we still be like this...no matter what happened...with Cali." Her mouth wrinkled up for a moment. "I'd rather lose Cali forever, than lose this for even a minute, if that makes any sense."

"It does," Eric nodded. "And I don't think it's crazy for you to get to have both."

"It's just been...a nice surprise, that I feel like I still have your love and respect as a sister, maybe even more so..." Cassie ran out of words. "I guess I didn't know how well you, or we, would be able to handle that part." She shrugged, feeling a little more emotional than she had intended. "I didn't expect that you'd be this...I don't know...mature about it."

"Cassie, I'm kind of making this up as I go, so I can't promise I won't screw everything up at some point," Eric shook his head. "But I will always love you...no matter what. I just want you, and Ellie, to be happy and feel good." He thought about it for a second. "This whole lockdown started out feeling like the worst thing ever, and now, it's turning into something..."

"Magical?" Cassie suggested.

"Yeah, like there is some weird enchantment or spell over everything since we started making wishes." He struggled to explain it. "Like everything we ever wanted was, like, right here the whole time...and we just never really knew it." Eric looked down at his coffee cup. "I just want to find a way to keep the magic going and not screw it up somehow."

"You're doing an amazing job so far," Cassie assured him. "It's been a little weird for me, but I can't ever remember feeling this excited, about what was going to happen every day...or this close, to you and to Ellie."

"Thank you for handling it so well." Eric looked so sincere. "I know Ellie can get a little crazy sometimes, but you could have been so different about all this."

"You mean more like the old Cassie," she rolled her eyes.

"Well...yeah." He hoped he hadn't hurt her feelings. "Sorry."

"No, I understand. I guess I just figured I had to look out for you guys. Like I had to be more of a grown up or something." She grimaced. "Somehow I ended up turning into this controlling bitch who just worried about every little thing."

"Hey, I didn't think that," Eric tried to comfort her.

"Well, maybe you didn't. But Ellie sure did and...well, I did too." It felt good to let it out.

"Well you're not like that now..." Eric encouraged her.

"And it's okay that I'm not?" Eric couldn't believe how vulnerable his big sister looked in that moment as her eyes searched his.

"I think it's amazing that you're not," Eric blurted out. "How it's been... the last couple days?"

"You liked it?" Cassie watched him carefully. "Really?"

"Cassie, I loved it." He glanced up at her briefly. "I love that you're letting me...act like that...around Cali." His eyes slowly rose to meet hers. "It makes me feel grown up and in control." He blushed. "I love that feeling."

"I love that it does, Eric." Cassie's heart was thumping. "I'm glad that it makes you happy, because I love it too." She looked at her tea cup, now almost empty. "You're the only one I can trust enough to do something like this with."

"So you won't get mad at me if I take it too far by mistake?" Eric asked tentatively. "Because I'm not really sure what to do, and I don't want to ruin it, and it seems weird to have to stop to ask Cali if it's okay." It came tumbling out, more awkwardly than Eric had hoped it would.

"No, you're right...that would kind of ruin it." She was surprised by how much he was struggling with those anxieties. Especially after how assured he'd been acting through the first day or so. She thought about it for a moment. "What about if we had a...a code, or something. Like if it got too uncomfortable, Cali could say something like, 'I think I need to go', or something like that. To let you know that...it's...too much, but without breaking the spell." She looked hopefully at Eric.

"Why not use exactly that; 'I think I need to go', then?" Eric felt relief wash over him. "So then I can back up a little and try to get it back on track, or if you're really uncomfortable, you can actually leave and it still won't break our agreement."

"You would let me do that?" Cassie was amazed at how much it relieved her. "That would be so perfect." They sat for a moment enjoying the sense of relief.

"So," Eric smiled. "Do you think Cali might be headed down to the beach later this morning?"

"I need about 30 minutes," she got up from the table to rinse out her coffee cup. It was hard not to run up the stairs.

Eric thought about checking on Ellie when he went upstairs to get dressed, but he was pretty sure she'd still be sleeping. They'd been up late the night before and he didn't want to wake her. He changed quietly and headed back downstairs to leave a note for Ellie on the kitchen table, asking her to join them at the beach when she woke up, before heading out to fuel up the generator and fire up a little oasis of paradise in the middle of a snowstorm.

By the time Cassie got to the beach, Eric already had it lit up and the temperature was rising quickly. The Spring Break decorations were still up, but they added a festive air after walking through the gray day outside, through the falling snow. Eric was straightening up a little and collecting the cups and objects they'd left lying around after their competition and party the day before. Cassie stripped down to her bikini and left her clothes folded on the bar.

"There she is!" Eric walked up to the bar beside her. "Hey Cali!"

"Hey Eric," Cassie felt a sense of joy just stepping into the Cali role.

"I was just going to take a break and get high. Care to join me?" Eric took his pipe out of his jacket pocket.

Cassie nodded and they stood smoking at the bar for a few minutes before setting down the pipe and taking their water bottles to the beach chairs.

"You ever notice how weed makes a hangover feel less severe?" Cassie mused after a few minutes. She stretched her neck from side to side and reached up to rub her neck and shoulder muscles.

"Feeling a little tight?" Eric noted her squinting as she rubbed her muscles.

"Yeah, I think I might've pulled something wrestling around yesterday. I was just too drunk to notice until this morning," she chuckled, remembering how wasted the penalty drinking had gotten her and Ellie.

"Well come sit in front of me and I'll see what I can do," Eric offered, patting the front edge of his chair.

Cassie got up from her own chair, grabbed her water bottle and eased her way down to the sand directly in front of Eric's chair, facing out toward the lagoon. Eric reached down and began working his fingers through the tense muscles in Cassie's shoulders and neck, slowly easing the knots and allowing her muscles to loosen. Cassie let out a series of humming sounds as the effect of the weed and the massage under the warm lamps allowed her to relax and enjoy the sensation of Eric's hands on her skin.

Cassie leaned forward as Eric's hands rubbed further down her back, isolating the muscles along her spine and around her shoulder blades. When Eric paused to untie the lower strings on her bikini, she didn't seem to mind as they fell to her sides, as it allowed him to rub the length of her back without them breaking up the sensation. After a bit, she felt Eric's hands return to her shoulders and guide her to lean back against him again. She might have been less alarmed that he also untied the strings around her neck, but he also gently pulled her untied top up off her after he did.

"You don't need this", Eric said casually as he set it aside and went back to rubbing her shoulders.

Cassie should have felt less affected by being topless in front of Eric, after she'd already allowed him to take her picture topless, and as many times as she'd been exposed during the Spring Break competition. But a large part of her still had trouble letting go of a lifetime of modesty, and the fact that up until the lockdown, no guy had ever even seen her topless. The fact that Eric had seen her like this, multiple times since she first exposed herself at his party, didn't take away from the fact that it was still a big deal for her to have her tits, that she'd spent a lifetime keeping covered, fully exposed like this around him. She fought the urge to cover herself with her hands and she could feel her nipples had grown swollen, hard and sensitive as even the small movement of air within the oasis reminded her from moment to moment that she was half naked.

"I like seeing you like this Cali," Eric murmured. "I think you should start a new tradition that it's okay to go topless at the beach. In fact, I insist."

"Don't you think it will seem weird to Ellie, if I'm suddenly running around with my tits out around you?" Cassie tried to imagine how Ellie would handle it.

"She would think it's weird if Cassie did it, but I think she can handle it if Cali does it. I'm kind of hoping she'll decide to follow your example," Eric ran his hands down the front of her chest and leaned over to cup both of her boobs in his large hands.

"You'd like that?" Cassie asked, suddenly more breathless than she expected as she felt her large firm tits engulfed in her brother's hands. "It wouldn't bother you to look at your own sister topless like that?" Her breath was coming in smaller, shorter bursts between her open lips as Eric's hands groped her however he liked.

"It will bother me a lot," Eric admitted. "But in a good way." He let his fingers slide down and softly pinch the puffy pink areolas and hard nipples of his older sister, as if he had every right to fondle her so intimately. "Do you think it's wrong that I want to see my sister like that?"

"I would never judge you," Cassie said demurely. "You should be allowed to do whatever pleases you."

"Do you think Cassie would ever be able to be comfortable, walking around exposed like that, around me?" Eric was finding this conversation much more exciting than he had even imagined when he took the chance of untying Cassie's top. Somehow getting her to talk about it was just as exciting as seeing and touching her this way.

"I don't think she ever would, Eric." Cassie felt her heart pounding in her chest. "It would be way too humiliating for her, especially around her younger brother. She's too modest, and has way too much pride, to ever let herself be exposed like that. I think she'd always worry that Eric would lose all respect for her if she did something like that." She could hear her breath coming in and out of her nose once she closed her mouth to swallow. Her mouth had suddenly gone very, very dry.

"It's really a shame," Eric said with regret as he gently kneaded a handful of his sister's full, firm tits in each hand. "Because Cassie has such a beautiful body. She's so different than Ellie, but I think she's so sexy in her own way." Eric leaned down to kiss the side of Cassie's neck as she rolled her head to one side in the sensation of his hands on her body. "Can I tell you a secret, Cali?" Eric whispered into her ear before he nibbled lightly at her earlobe.

"You can tell me anything, Eric." Cassie whispered back, after letting out a small gasp.

"Sometimes I think about Cassie when I'm jacking off," he whispered, his voice trembling with excitement.

She gasped again as he pinched her nipples a little more roughly and tugged them lightly as his fingers stroked them to a point. "You do?" she felt her pussy release a wave of wet excitement.

"You don't think it's wrong for brothers and sisters to think about each other, when they...pleasure themselves...like that?"

"I think it's very wrong, Cali," Eric admitted in a whisper before kissing her neck again. "But that's what makes it more exciting." His lips and teeth went back to her earlobe and shivers ran through Cassie's body. "Does Cassie ever think about me like that?"

"I don't think Cassie could ever admit to something like that...to anyone." She was almost panting now.

"If I was your brother, would you get excited thinking about me like that?" Eric cupped her tits and lifted them possessively.

Her answer was so faint as to be almost inaudible above the sound of the generator. "Yes," she whispered breathlessly.

"Speak up, Cali," Eric prompted her. "I want you to say it louder.

"Yes," Callie said in a trembling voice.

"Yes, what Cali?" Eric spoke and fondled her more firmly.

"Yes, I'd get excited thinking about you like that," Cassie's chest was rising and falling as her breathing had gotten deeper, but her breasts remained suspended in Eric's firm grasp. "Even if you were my brother."

Eric's hands left her tits and one traveled up to the side of her neck, while the other shifted to her other breast. Eric turned Cassie's head toward his own and tilted it up before plunging his tongue into her parted lips and kissing her deeply. "Thank you, Cali. You've been a very good girl." He kissed her again as her mouth hungrily devoured his tongue and his kiss, her breast trembling with excitement in his firm grip."You...you don't think I'm...a...bad person...for...for thinking that," she asked breathlessly.

"No Cali," he planted light kisses on her jaw and along her chin. "I think you're amazing." He kissed her softly on the lips. "I think you're beautiful," kiss, "and sweet", kiss, "and sexy", kiss, "and it turns me on to think about you getting excited like that," kiss, "touching yourself", kiss, "thinking about me", kiss, "the way that I think about Cassie."

Cassie fought the urge to reach down and touch herself in that moment. "Did you...did you look at Cassie's picture...when you...?"

"I have," Eric kissed her lightly. "Twice already." Cassie let out a small moan against his lips. "Do you want to see her picture Cali?" He kissed her chin. "Do you want to see what I looked at?"

Cassie nodded, her lips barely brushing against his. Eric stood up and swung a leg over Cassie to walk over to his pants on the bar and remove his phone. Cassie leaned an elbow on the chair, half turned to watch him. When he turned back toward her, she wasn't at all ashamed to stare at the large tent of fabric sticking up in his trunks as he walked back to the chair. She knew that his excitement was all for her.

Cassie stood up on her knees to allow Eric to sit back down and scooted closer to him once he'd gotten settled, her forearms resting on his knees and her tits shamelessly exposed to his view as she waited for him to pull up the picture. She reached down to get a drink of water as he unlocked his phone and opened his folder of saved pictures.

"Here she is," Eric turned his phone to Cassie. "Look how vulnerable she looks," he fondled her tit as she leaned over to look at the picture.

"I can't believe she let you take her picture like that," Cassie felt jittery and weak seeing herself that way, knowing that Eric could see her like that whenever he wanted. It made her throb to think about him having that much power over her.

Eric slid the picture over with his thumb, revealing Ellie, with his cock buried as deeply as she could in her mouth. "Can you believe Ellie let me take her picture like that?"

"She didn't make you delete it after she won?" Cassie stared in fascination, seeing Elli's pretty face, her full pink lips, stretching to fit as much of her brother's thick, meaty dick as she could into her mouth. "I can't believe she did that."

"I can't help wondering if you backed out just to let her win," Eric's heart raced and he hesitated. "Or if you would have really won...if you tried." He wondered if he'd pushed it too far. If she was about to use the phrase they'd agreed would allow her to slow things down.

"I...I don't know," Cassie looked up from the phone. "I've never done something like that before." Her eyes dropped away from his. "With anyone," she admitted.

"I think you should try, Cali," Eric said gently. "No one would ever know," he assured her.

"You wouldn't think..." Cassie couldn't look up at him. "You...you...really want me to?" Eric could feel her hands trembling on his thighs and he felt like his own heart had stopped in his chest, waiting for her reply.

"I really would." Eric felt his throat tighten, his mouth suddenly very dry. His cock twitched beneath the thin fabric of his trunks.

Cassie saw his trunks twitch out of her peripheral vision, but never looked up. She stared at the image of her sister with a mouthful of her brother's dick and after a long pause, she sat back onto her heels, head hanging down and nodded her head, ever so slightly. A halo of light reflected from her silky black hair, but her downcast eyes, and the way she pulled her full lower lip in between her teeth, were obscured by the shadows formed by the way her long hair draped along each side of her face.

Eric rose slowly, grabbed his water bottle and walked over to the spot in front of the bar where he'd taken Ellie's picture the day before. Cassie hesitated for a moment, but grabbed her own water bottle, and followed obediently a few steps behind him. Eric took a long drink from his bottle before setting it on the bar and set his phone down to untie his trunks.

Cassie felt like she was watching herself from somewhere far away, somewhere back in her mind. She didn't know where she'd found the courage to follow Eric, over to the spot in front of the bar where she had kneeled the day before. Every consideration of 'Cali' vs. 'Cassie' had long since dissipated in her thinking. She certainly felt high and detached from smoking weed, but realized that the intensity of her arousal was affecting her just as deeply. She took a long drink after watching Eric set down his own bottle, but wondered if her mouth would dry out just as quickly again, as it seemed to have repeatedly in the last few minutes.

Even as Eric dropped his trunks to his ankles and she saw his rigid dick revealed, she looked at it as an objective outsider, wondering if the woman she was looking out at the world through would actually go through with it. Like the wind up to rock/paper/scissors, her mind spun with whether or not Cali would tell Eric that she thought she should leave before she went through with it. Time slowed as she dropped to one knee and then lowered the other. She wondered in a fuzzy way if the fact that her legs had obeyed the command to kneel in fact also meant that she really intended to go through with it. If she could will her body to comply and open her mouth to accept a man's penis. No, not a 'man's' penis. 'Her brother's dick', she thought. Eric's dick.

For the first time since she'd knelt, she looked up at Eric and saw him looking down, eyes locked onto her, as her face hovered just inches from his throbbing dick. She watched him swallow in slow motion and his Adams apple seemed to take forever to move up and down under the skin of his throat. She looked into his wide eyes and he blinked repeatedly, his eyes shifting slightly between her own eyes, her mouth and his dick that he held down with his hand, to keep extended out, and level with her mouth.

She brought her gaze down to face the bulging tip of his pink dick a few inches away and part of her marveled at its size. It seemed unreal that Eric should have a part of him that was so intimidating and she wondered how something like that could ever fit inside of any intimate part of her body. Her mind whirled with remembering the sensation of looking down from the high dive, just before she backed out yesterday, and the pang of regret that she'd drunkenly felt after she hadn't gone through with it, even as Ellie had spanked her afterwards.

Her heart thudded in her ears as she considered whether deep down she even wanted to do this, or if it was just to please Eric, because he'd asked her to. She could admit to herself that the idea of putting a man's penis in her mouth seemed degrading and disgusting, at the same time, some part of her knew, that as much as she wanted to please Eric, there was some deeper truth that was making her even consider going through with it. She knew that if she did this thing, she would have left the old Cassie forever behind once she had. If the old Cassie would have been able to live with the shame of knowing her brother had taken her picture topless in a moment of weakness, that same Cassie would never be able to accept the fact that she had sucked her own brother's dick. It was as simple as that.

Cassie swallowed hard, closed her eyes tight and opened her mouth. She couldn't bring herself to move forward and stayed frozen like that for a long instant before she felt a movement in the air in front of her and Eric's dick bumped against her tongue as he began sliding it into her mouth. It felt smooth and warm as it slid along her tongue and she willed her mouth to close around the thick mouthful of dick as it filled her mouth. It surprised her that it simply felt like large, thick tongue depressor, of warm soft skin against the inside of her mouth and she opened her eyes, to see the lower part of Eric's stomach and the patch of light brown pubic hair that led down to the base of his cock.

"Just hold it whenever you think you've got the most in that you can fit Cali," Eric said huskily. Cassie closed her lips around the thick, meaty cock filling her mouth and pushed slightly forward against the head of it at the back of her mouth, until she was afraid that she'd gag if she went any further. She heard a small click to one side of her face and then she was sliding her mouth away, grateful to be able to swallow freely again.

Cassie sat back on her heels and stared down at Eric's swim trunks, piled up carelessly around her brother's feet, while she tried to process the fact that she had just let him put his hard dick into her mouth. Her pussy throbbed when she told herself that it was worse than that; she had pushed against it to fit as much of it as she could into her mouth. If she thought she'd have a moment to regroup, she was swept up instead, as Eric lifted her to her feet and wrapped her in an enveloping hug.

"I can't believe you went through with it," he said breathlessly into her neck. "I was sure you were going to back out again, but you did it, Cassie! You really did it!" He pulled back to look at her face but her eyes wouldn't rise to meet his. If she was surprised at being lifted up so quickly, she was stunned that he began to pepper her with small kisses, punctuated by saying, "thank you...thank you...thank you" as he delivered them. She felt a smile creep over her face at his exuberance and she couldn't help but be swept up by his excitement. She smiled with her head on his shoulder and patted his broad back as she felt his bare hard cock pressed up against her stomach. Her hand slid down and rubbed his toned butt and felt him kiss her on the shoulder.

"It's Cali by the way," She said softly into is ear.

"Oh, yeah right," Eric laughed nervously. "I'm so sorry. I..."

"It's okay," she patted his back and pulled away. She picked up her water bottle and walked back to sit down in the beach chair, looking out over the lagoon.

"Cali," Eric's voice came closer as he walked up behind her a minute later. "Ummm...I really think you're the rightful queen."

Eric held his phone up to flip back and forth between the two pictures, pointing out the skin variation on the shaft of his penis and how it aligned with her and Ellie's mouth in the pictures, even pulling his hard dick out to show her exactly how much of his cock she had held in her mouth. But all Ellie could see was herself, photographed with Eric's dick in her mouth. She was consumed by a potent combination of shame, arousal and fascination to see herself like that while Eric spoke excitedly, flipping back and forth between the two pictures, showing each of his older sisters, with his dick buried in each of their mouths.

Eric settled down at last beside her and produced the pipe to take another drag before passing it to Cassie. She took a hit and let the plume of smoke escape before drinking the last of her water. She felt a need to be alone for a minute and process everything that had just happened.

"You know what I really feel like? Something to eat and a real drink," Cassie suggested. "Maybe I'll head up to the house to fix a sandwich."

"That's a great idea," Eric stood up, full of nervous energy. "Why don't you relax and let me go make some sandwiches. I'll grab some drinks and see if Ellie is awake and ready to come down." He was getting dressed before she had a chance to object. He turned on the boom box while he was at the bar and switched it to a local radio station before he left.

At least with Eric gone, Cassie had a chance to relax and regroup for a little while. Even the walk to the house and back would take him ten to fifteen minutes in the snow and he would need additional time to fix food and check on Ellie. Cassie leaned back in the chair, closed her eyes and let the music from the boom box wash over her as she wondered if she had just made the worst decision of her life. Try as she might, she kept seeing the image of herself with a mouthful of Eric's dick and remembered how time had stood still as it had been happening.

Cassie told herself to stop being such a baby about it, as practically every woman she knew, and probably more than a few of the guys, must of had a dick in their mouth, at least once, and it didn't seem to have done them any lasting harm. Even Ellie had done the same thing less than 24 hours earlier. She remembered watching Ellie, as his dick entered her mouth, and felt suddenly flush, wondering how it must have looked for Eric as he watched her do the same thing.

In the background, a Lana Del Rey song came on the radio, weaving a hypnotic beat with lyrics that dripped of decadence, submission and desire. Without even thinking, Cassie began to rub herself through the thin fabric of her bikini bottom, as her pussy throbbed in time to the music. Knowing that she was alone under the pulsing warmth of the lights, Cassie slid the fabric of her swimsuit over to one side and slid her fingers into the slick folds of her pussy, flickering one fingertip lightly over her clit while another slid deeper inside her, rubbing the sides as it slid in and out.

Within moments she was rubbing herself with an intensity that completely surprised her as the weed, music and memory of what she'd just done made for a potent aphrodisiac. She was climbing to the peak of desire, matching her building climax to the sound of Lana's rising voice when she jumped out of the chair with a scream, when Ellie's voice said softly, a foot or so above her closed eyes:

"That is the hottest fucking thing I have ever seen."

Ellie had already been walking through the snow, on the way out to the beach, when she met Eric coming the other way. They stopped between the outbuildings to kiss and Eric told her he would be back in a few minutes after gathering some food and drinks from the house. He gave Ellie's tits a squeeze through the thick padding of her coat and told her that Cassie was still at the beach, and had a surprise to share with her, that he thought Ellie would enjoy.

As Ellie had come around the last building, she could hear the sound of the music over the loud drone of the generator, and see the warm light of the lamps, bright and distorted, through the painted plastic sheeting, in bright contrast to the gray day. When she'd slipped into the flap, she could see that Cassie was sprawled out in one of the beach chairs and didn't look up as Ellie crossed the sand behind her to begin undressing by the bar.

Ellie figured that Cassie might have fallen asleep in the chair and had the idea to sneak up behind her and give her a little scare if she had. As Ellie walked up to lean over the back of the beach chair though, she instead found Cassie topless, writhing, and deeply focused on bringing herself to an orgasm, that didn't seem very far off at the moment. Ellie watched in fascination as she tugged at her own nipple, through the fabric of her top, and couldn't resist rubbing herself through the fabric of her own suit, caught up as the sensuous music, and the sight of her prissy sister, nearly naked and diddling herself, sent her heart pulsing.

By the time she spoke, she was very worked up and meant every word of what she said:

"That is the hottest fucking thing I've ever seen."

Cassie scrambled to her feet and wheeled around in a panic to find Ellie standing open-mouthed behind the very chair, where just moments earlier, she had been bringing herself to an orgasm, thinking she was completely alone.

Cassie clutched at her bare chest, her heart thudding, and screamed, "Ellie! What the fuck are you doing!?!"

Ellie broke into a stunned laugh and blurted, "Watching you fingering yourself." She looked at Cassie's heaving chest and beautiful firm tits, quivering as she nearly hyperventilated. "Sorry I scared you, but I think you should go ahead and finish." Ellie sat down in the other chair and lit the pipe.

Cassie staggered back to her chair, shaking all over. "How fucking long were you there? I...I thought you were at the house?"

"I was, but I just met Eric walking over here. He's bringing back lunch and some drinks." She took another hit from the pipe and held it in.

"I know...I...I...thought it would be a while before he got back...I...I..."

"And you felt like you needed a little 'alone time' to satisfy yourself while he was away." Ellie blew out the smoke as she spoke. "I get it. Sorry I interrupted. I didn't mean to freak you out."

"You scared the crap out of me, El." She held her hand to her chest as she sat back in the chair and adjusted her bikini bottom.

"Well you can't stop now," Ellie complained. "It sounded like you were really close."

"Are you fucking kidding, Ellie?" Cassie was starting to calm down but was mortified at having been caught in such a compromising act.

"Not at all, it was kind of getting me off watching you, Cass." She looked at her sister's body. "I want to watch you finish," she smiled mischievously. "Please?...pretty please," she pleaded.

"Umm...no!" Cassie protested. "There is no, fucking, way, I'm doing that in front of you."

"Ummm...yeah, Cass. You kind of already did?" Ellie reminded her. "I just want to watch you do it some more." She bit her lip. "I'll even do it with you."

"Are you fucking crazy? Eric could literally walk back in at any minute. I've already been embarrassed enough for one day. I don't need him to find out too."

"I figure it will be at least another ten or fifteen minutes, so we have plenty of time," Ellie insisted. "Plus, if you don't, then I'll have to tell him all about how I caught you with your top off masturbating when I got here." She smiled and shrugged. "So you can finish and we'll keep it a little secret between us girls, or he's already going to find out when you get back."

"You'd really tell on me, El?" Cassie turned red again.

"Not if you get busy, Cass." She knelt down between them. "I really wanna do this with you and I think you'd love it, if you just stop wasting time and get on with it." She put her hand on Ellie's shoulder and thigh. "Would it help...if I did another body shot off of you?" She smiled seductively at Cassie.

"What...no...I..."

"C'mon, Cass." Ellie reached up to grab Cassie's boob and rubbed her thumb over her hard nipple. "You know you loved it as much as I did." Cassie stammered, about to protest, but gasped as Ellie bent from the waist to take her nipple into her warm, soft mouth.

"Ellie...oh my g...Ellie...I can't be-lie...ohh," Cassie's hand reached up to stroke the back of her sister's hair as Ellie sucked on her tit and grazed her hard nipples gently with her teeth.

Ellie reached over and grabbed Cassie's right hand to pull it back where it had been when she found her, pressing it into her mound as she dropped her own free hand down her swimsuit bottom and began fingering herself.

Ellie paused from sucking Cassie's swollen nipple. "Would it help if I pulled down your pants and spanked you some more?" Ellie winked at her before taking another playful suck at Cassie's tit. "I could smell you yesterday as I spanked you." Her mouth plunged back down on her sister's hard, tingling nipple.

Cassie looked at her sister with a mouthful of her tit, pressing her hand into her pussy while she fingered herself and Cassie began sliding her own fingers back into their well practiced rhythm of pleasure.

She thought it would take her a long time to get back to the place where she was before Ellie scared her, but Cassie was surprised to find that she came almost immediately as she watched Ellie suck her tit and felt her moaning into her nipple. Ellie's hand never left the top of Cassie's as she rode her fingers to a throbbing orgasm.

As soon as Cassie stopped cumming, Ellie lifted her mouth from Cassie's tit, pulled down her bikini top as she rose up higher on her knees and pulled Cassie's head over to suck her own swollen nipples, still kneeling beside Cassie's chair as she fingered herself and looked down to admire the sight of Cassie returning the favor by sucking her tit."That's it Cassie, suck it harder....mmmm....suck your sister's tit, baby...mmmm...mmm...I'm cumminnnng...." Ellie flopped back onto the sand and rode her hand through the waves of orgasm as Cassie watched in fascination, She'd never even seen another woman masturbate before, let alone reach an orgasm. Ellie's curvy little body undulated against her hand, her big, soft tits jiggled beautifully and she let loose a symphony of whimpering that seemed so raw and elemental compared to the restraint that Cassie exercised as she experienced her own orgasms.

Ellie finally climbed up onto the other beach chair, lying back as her breathing slowed. Ellie sat up, undid her bikini top from around her waist and flung it to the side before finally turning to look at Cassie through squinted eyes. "See, I knew you'd like it." She sighed and laid back, closing her eyes in contentment.

Even though Eric had wanted a chance to see Ellie at the house and have a few minutes alone, knowing both of the girls were at the beach, he wasted no time running up the stairs and pulling up their pictures on his phone before dropping his pants.

It had been one thing to get a picture of Ellie with his dick in her mouth, but there was no conceivable way he would have ever thought that Cassie would agree to have her picture taken like that. Looking at her picture it turned him on even more to see that her eyes were open a little and he could see her looking ahead as she waited for Eric to take the picture. Eric kept sliding between the two pictures as he stroked his cock, but it was Cassie's eyes that he was looking at as the first load of cum started squirting from his cock.

By the time Eric got back to the beach, the girls were talking languidly in the beach chairs and it looked like they had been in the water not long before he'd gotten back. He called out to them over the music and as they got up to meet him at the bar, Ellie called out, "Cali and I decided that this beach is now clothing optional. Hope you don't mind!" They both walked over topless to the bar and Eric beamed that he would be able to see them like this as much as he wanted.

"Sounds...and looks, good to me!" he called out as he started to peel off his coat and knelt down to unlace his boots as the girls began unpacking the sandwiches and pouring drinks.
