Dad got his wish 2

For the next three days, Justin thought and pondered over where things were going with Katherine. It was a route he had never intended; and one that both troubled and excited him. She made him feel in ways he had never felt before; but the nagging thought this was his sister kept bubbling to the surface. Finally, just when he thought he had worked up the nerve to talk to her; Katherine floored him once again.

Coming home from working second shift, everyone in the house was sleeping and Justin quietly picked his way through the darkness to his room. Closing the door, he flipped on the light and then he stepped to his desk to drop his keys. Sitting on his desk was the hundred dollars he had given Katherine for being his prom date. It was resting on a note.

His heart sank as he picked up the hundred, and then the note. She was calling it off, he thought. No prom... While his dad would be pissed off, he knew she was right. Then he looked down at the note.

'I want to do this because I choose too, not because you paid me.'

As Katherine's words sank in, Justin wasn't sure whether he was scared of what might come next or thrilled his dad would get off his back if it did.

For the next week, his father kept going on and on about the upcoming prom and Justin's date. Every time he bragged about 'his boy' bagging some hot high school girl, Katherine would just stare at him and then shake her head. It was so bad his father gave him money for a tuxedo, and bought him a fresh box of condoms, which he flaunted at the dinner table making Justin blush as Katherine looked on.

On prom night, he was in Jess's house waiting for Katherine to get ready.

He heard her coming down around the corner of the hall. His first sight was red painted toes in a pair of strapped high heels. As she came closer, his eyes traveled up her calves and lower legs, to the expanse of firm tanned thighs. The hem of her rose dress ended just above mid-thigh, low enough to be proper, but high enough to create the threat if she bent or moved wrong.

By two more steps, he didn't know which way to look. That firm ass that the skirt flowed over. Or the taut belly clearly visible through the rose lace of her top. It was so sheer; Justin could see the glint of silver from her belly button piercing.

But it was when she got to him, he almost stopped breathing. The rose lace continued up and over the curve of her breasts. The sheerness highlighting the globes of flesh they barely hid; the dress had just enough thickness at the right two spots to hide the caps of breasts, taking the nipples from his view. There was no bra, he realized. The top was tied in a single bow at her neck; and the back, well, there wasn't one. Bare tanned skin ran the full length down to just barely above the crack of her ass. It was apparent she also had no panties.

"You can breathe now", Jess's amused voice sounded in his ear.

"Oh my God", Justin let out with his held breathe. Katherine looked at him in surprise. "You're stunning", he said more softly.

"Thank you", Katherine gave a demure smile. "Shall we?", she asked softly.

All through the drive Justin couldn't tear his eyes from her; he was still in shock at how stunning this tomboy sister he had never noticed was. It didn't help that the obvious tent in his slacks showed his approval. Katherine said nothing as he kept stealing glances; she just sat quietly with her hands in her lap.

As they entered the dance hall that had been rented, Justin felt like he was on cloud nine; there was no doubt the most beautiful girl here tonight, was on his arm. He had purposely given them an extra half hour so that people would already be present, and their entry would hopefully not be noticed by some; unfortunately, he was wrong.

"Yo Dawg!", rang out behind them; and Justin felt Katherine stiffen in his arm.

"Hey Reilly", Justin acknowledged him.

"Your Dad must be a very proud man tonight.", Reilly offered.

Before Justin could retort Katherine spun on her high heels and faced the young man. "That's because his Dad knows Justin is going to fuck my brains out tonight", her sultry voice spoke as she looked at him.

Reilly's mouth dropped open at her frankness.

Katherine turned back to Justin. "I think it's time we danced", she said. Grabbing Justin's arm, she spouted, "Shall we?"

"Holy fuck", Justin let out his breath as they moved towards the dance floor.

She turned back to look at Reilly, his mouth was still agape. "You be sure to tell Justin's dad.", she yelled.

He wrapped his arms around Kat and pulled her close. It was such a contrast to him; the swiftness and power he had seen in her reaction to Ricky; and the soft feminine form he now held.

Justin reveled in Katherine's closeness as she never was far from his side. Small touches from her hands, the smell of her hair when they danced; all of it made the evening pass like a swift bolt of lightning. He had lost count of how many dances there had been; both fast and slow; and as the band began to play the midnight lovers song, he knew what he wanted.

"This has been the most perfect night, thank you", he whispered into her hair.

"Not 100% perfect yet.", Kat's voice was a soft murmur.

Justin's eyebrow raised, "Yet?", he questioned.

Katherine pulled his face to hers, and her lips ascended to his. Her tongue slipped into his mouth. She felt one of his hands slide lower, all but cupping the cheek of her ass. She knew this was so wrong, but she wanted to stop her dad from pressuring Justin. And she knew he wouldn't lie. As their lips parted, she looked into his eyes.

"We need to leave" she said softly.

Justin nodded; and the two headed over to gather their things from their table. Katherine was silent as they headed for his truck, Justin wanted to ask what she was thinking, but was terrified of her answer. As he slid into the driver seat, Katherine looked over at him.

She said, with lust in her voice, "I rented a motel room."

"You're not wearing panties". Justin didn't even look at her, instead he stared out the windshield.

"You need to drive...NOW!!", Katherine told him.

The drive to the hotel was silent, and Katherine never left his side as they checked in. Together they rode the elevator to the fifth floor and walked down the hall to the room door. Kat used the key card and opened the door; he stepped into the dark room and looked back at Katherine standing on the threshold.

"Are you all right?" Are you sure?" he asked nervously.

"I just run my finger over my very wet pussy.", she said. As she moved her finger to his lips, she spoke again, "you tell me?"

"Justin...I cross that threshold I'm no longer your sister...I'm your date." She stared at him, "do you understand?"

Justin reached out and gently took her hand; and then swiftly jerked her forward. With a squeak Katherine half stumbled through the door and into the room, plunging into darkness as the door closed.

"Jus..mmmmmmmmmmmmmmm" her words turning to a moan as his lips smashed into hers, his weight pinning her to the wall beside the door.

"Oh God yessssss", Kat moaned as his lips began to travel down her neck.

"God I want you", Justin disembodied voice echoed in the dark.

"Then take me...I'm yours!!". Kat moaned as his hot lips traveled over the lace of her dress.

Like frenzied animals they tore at the others clothes. His jacket went flying to the floor, followed by his shirt; as Justin pulled the bow at the back of her neck, causing the top of her dress to fall free.

"Oh God suck them", Kat moaned as hot lips wrapped around her rock-hard nipple.

Katherine shimmied her hips as Justin tugged her dress down; at the same time her nails clawed at the front of his slacks. Justin moaned as he felt her hand wrap around his rigid cock.

"Fuck, you're so hard" Katherine whispered.

Justin released her nipple and rose, pinning her against the wall. His hips ground into hers as his cock searched for her opening.

"No", Katherine husked as her hands pressed against his chest. "Not like this" she told him.

He heard her hand sliding along the wall, and then the dim light of the entry way to the room came on. Katherine looked around and saw the bed; taking Justin by the hand she led him over and had him stretch out on the bed on his back.

Katherine leaned over and tapped the base of the bedside lamp, bringing it to life. Justin blinked and his eyes adjusted to the light as a nude Katherine climbed onto the bed and straddled his hips.

He watched as she reached down and gripped his cock, holding it upright, her hips easing down until the tip nestled into her dark hairs; he could feel her moisture seeping onto his cock head as she positioned herself.

"I want to see your face", Katherine said. "I want to see you when you slide inside me" she husked.

Justin opened his mouth to answer, but all he got out was a low guttural moan as pure heat surrounded his cock. It started at the tip and slowly slid down until he felt her pelvis grind into his.

"Oh God yessssssssss", Justin groaned.

"Oh my fucking God", Katherine breathed out.

For the next ten minutes neither could speak as Katherine rose and fell on him. Sucking noises filled the room, and the smell of their sex hung in the air as she rode him.

"Oh God...Justin...never felt...oh shit...I'm going to cum...I never...", Katherine began to babble as her body bounced faster and faster.

Justin reached up and gripped her hips, watching her face; he waited, and just as her body began to violently tremble; he pulled down on her, impaling her on his thick cock.

"AWWWW FUUUCCCKKKKKKKKKKK", Katherine screamed as her body convulsed.

Her hands slapped down on his bare chest, her nails digging into his skin. He felt her thighs quiver as they tightened around him. A hot splash of fluids across his groin drenched him in her juices. Her body slowly eased down until her head rested next to his; her breasts pressing into his sweaty skin.

Neither was moving and yet he felt her walls squeeze and relax around his cock as waves rolled over her. It felt like she was milking his cock, and he could feel his balls begin to ache.

"Kat...oh God", he moaned. "You need to get off...I can't...oh fuck..." he moaned into her ear.

"God yes...cum for me", her voice was hot against his neck.

"Oh shit" he was getting desperate. "I'm not wearing a condom!", he was trying to lift her hips up off his now pulsing cock.

"I know", Katherine ground her body down harder, holding him to her body. "Have you ever fantasized of cumming in me?", she asked softly.

"Oh my God Kat, yessss" Justin moaned as his balls tingled.

"Then do it", she leaned down pressing her firm breasts into his chest. "Cum in your date...cum in your sister", Kat told him.

Justin reached up and wrapped his arms around her back, and then slid his hands down her smooth skin to fill his hands with the firm globes of her ass. With a grunt, he heaved his hips upward and twisted her. With a squeal Katherine landed on her back, Justin's cock still buried to the hilt inside her.

Pushing up on his knees between her spread thighs, he gripped her ankles and lifted her legs to his shoulders. The silky feel of her nylons drove his crazy as he began to pound into her.

"Oh God yes, fuck me...don't stop...oh shit...so good.", Katherine babbled as Justin hammered into her.

Justin watched her head roll from side to side as she clawed at the bed sheets. He could feel her tight walls rippling around him as her hips lurched up to meet his; the sound of skin slapping together filling the room.

The smell of their sex filled his nostrils; the sounds of Kat gurgling and whimpering under him in raw pleasure sent tingles down his spine that settled in his balls.

"Oh shit...Kat" Justin felt his balls tightening. "I'm going...to cum" he moaned between thrusts.

"Do it" Katherine hissed up at him.

"OOHHH MY GAAWWDDDDDDDDDDDD" Justin roared.

He jammed his hips down hard, impaling himself in that hot cavern' he looked down at his sister in shock as his cock jerked; the first thick wad pumping deep inside her.

Katherine felt that incredible heat fill her pussy, her eyes staring wide up at him. "So fucking good!!", she managed to whisper out as her second massive orgasm on the night slammed home.

Justin gripped her convulsing hips as hot juices splashed across his lower belly. He watched his sister's eyes roll back as her orgasm roared through her, even as his balls spewed a second and then third thick rope into her.

"Holy fuck" Justin gasped as he tried to catch his breath

"That was incredible" Katherine cooed into his ear.

"God I am in so much trouble" Justin whispered.

"What's wrong" there was a tremble in Katherine's voice.

Justin raised his head and stared into her eyes.

"Because I just fucked my sister came insider her", he stressfully moaned.

"Don't worry, I'm on the pill", her voice whispered back.

"What now?" Justin looked at his sister.

"Dad will get off your back", she laughed.

He smiled, looked at her and said, "the room is rented all night, right?"

Katherine swiveled her hips slowly, feeling his still hard cock embedded inside her sopping wet pussy. With a glint in her eye, Katherine shoved her hips upward, causing Justin to tip sideways. This time it was his sister as the pair rolled over once more until she was seated straddling him.

"Yes. Your date needs to be fucked again!!", she smiled.

'Get 'er done boy', was all Justin could hear in his head…

Justin reached up and gripped his sisters' hips, her words setting off a flame in his balls. With a lunge he lifted his ass straight up, impaling her on his dick.

"FUUCCCKKKKKKK YESSSSSSSSSSSSSSSS" Katherine screamed, as the pair began to fuck again.
