"Sorry," I started to protest but she cut me off.

"I understand why you did touch me. The situation was intense," my sister laughed desperately looking away from me. "I can't say I didn't like it. I came. My brother sucking on my tit made me cum. For the first time since God knows when. I know it's wrong but your right this whole situation is not natural. It's beyond normal laws and morals."

"I can't deny there is an attraction. You seem to like me. Physically. And I can't say little brother watching you walk around shirtless with your 6 pack abs and chest, seeing your dick hasn't effected me as well. Despite my protest. Obviously," my sister in doctor mode analyzing the situation of a brother lusting for his sister.

"I need time to think. Please don't harass me. I have to think about things. Deal with it. I'm not sure if I can do that with you, have sex. Incest. That's a line I've never even thought about crossing before coming here. Having sex with my little brother," my sister shook her head. "Believe me I'm horny, all the time. I almost let you put your cock in me. But it's you, my brother. Who I've always loved. But not like that, sexually. Please give me space." My sister's blue eyes locking eye contact with my identical blue eyes. "Don't make it any weirder. Give me time to think things over."

I said quietly, "Of course." I thought to myself I'll give you "some" time but not too long. Now I know my sister is attracted to me and horny, that's information that a perverted little brother should never have.

Day 66

The temperature outside was unbelievably hot. The hottest day I can remember in my entire life. My sister and I had been getting along well the last week. We started to do things together again, playing chess and checkers. We laughed about stupid things that happened when we were kids and told stories about crazy things we did with our friends. The mutual masturbation session though not discussed was evident in the way we treated each other.

My sister knew I wanted to fuck her. She would catch me staring at her ass, mesmerized by her camel toed pussy or ogling her tits. Mandy would simply shake her head and smile. "My own brother eye fucking me," my sister said once. I think my sister was enjoying being a woman again, being desired. I kept a respectful distance physically. I didn't touch my sister at all other than patting her ass once or twice during the course of the week. "You love this thong don't you. Gentle, my cheeks are a little sun burnt," my sister said playfully.

My sister and I had finished playing a game of chess. My genius sister had barely beaten me with a strong attack from her knight. We were hiding out in the shade sitting at a little table and chairs set we had made. Both of us sweating profusely. My glistening sister wiped sweat out of her eyes and stated, "I would do anything for air conditioning right now. Anything to just forget about the heat."

I was starting to get frustrated waiting for my sister to make up her mind about what to do. We could be rescued any day. I was starting to think my sister was stalling for time, putting me off. I smiled at my sister and said, "I can think of only two things to do to forget about the heat. 1. Go for a swim or 2. I'm not supposed to talk about that with you right now. I guess I'm going for a swim." My sister grinned at me slightly as I walked off towards the beach. I heard my sister say behind me, "That's all you think about little brother."

The water was calm, blue and warm. I thought to myself people would pay thousands of dollars to be left alone on this island for a couple of weeks. Why is there no one here? I had forgotten to take the towel with me I realized as I walked to shore through the small waves. The heat would bake me dry in minutes.

My sister was standing on the beach holding the towel waiting for me, "I brought you the towel," she said.

"Thanxs, seriously you should go in the water, it will cool you off."

"I washed my hair this morning, I don't want to get it wet," my sister's words reminded me that woman are the same no matter where they are. My sister said softly as I dried my body with the towel, "I decide we should do the other thing to beat the heat, little brother."

I looked up at my sister in her tan thong and small bikini top and was stunned speechless.

"Three conditions," my sister demanded, "one if or when we get back to civilization neither of us tells a soul. Not Alyssa, Brian, our parents, god forbid, your best friend, your wife of twenty years, my husband of fifty or my future psychiatrist or your future AA group. No one." I simply nodded.

"Two, back in the real world this is completely forgotten, even between us. Neither of us ever mentions it, hints at, eludes to it, I don't want you eye fucking me or staring at me in a bikini. We go back to normal brother-sister relationship. No way does it every happen again in the real world. Don't even think about. I'm serious, if this ever got out my career, my life would be destroyed. It'd kill me. We have to go back to being a normal brother and sister."

I simply said, "I understand." I didn't know if it was possible to be normal with your sister after you fucked each other but I was willing to agree to anything.

"Three you have to wear a condom. Getting pregnant while stuck on a deserted island with my brother would pretty much tell everyone that we had sex. That I had sex with my own brother." My sister had just said we had sex, her and me.

"You're right. I'll go get a condom."

My sister grabbed my wrist, feeling her touch me while we talked about having sex. My cock was instantly hard. "Not here on the beach, let's go back to the ship. Knowing my luck we'd finally get rescued while I'm letting my brother fuck me. It'd be a little embarrassing especially once they found out we our brother and sister."

My sister and I walked in silence back to the ship. I didn't dare say anything that might risk my sister changing her mind. When we entered the ship I continued on to my bag to grab a condom. My sister sat down on her bed I watched her beautiful ass in that thong as she bent down to get on the mattress. I opened up the wrapper and pulled out the condom, dropping the wrapper in our little trash bin.

My sister reached back and unsnapped her bikini top unleashing her D cup breast. Her nipples huge poking out from the excitement of the moment. I was about to fuck my sister. This can't be happening. This shouldn't be happening. My sister took off her bra and placed it on the floor. My sister reached down and started pulling off her thronged bikini bottoms. My sister lifted her ass allowing her panties to glide over her ass cheeks and then past her pussy onto her thighs. My sister's pussy freshly shaved, bald, her lips dewy with sweat or excitement.

My sister shyly looked up at me for a second and pulled her thong down her legs and off her feet. My sister completely nude, her beautifully tits heaving with excitement, her pussy waiting for my cock. I was mesmerized. My sister looked up at me enjoying the effect her body had on her brother, "Gavin, little brother."

Desire pulsing through my loins, my body on fire, I pulled down my swim trunks and stepped out of them. I placed the condom at the tip of my cock and uncoiled it down the head than the shaft of my dick. I looked at my sister as I slipped the condom on. My sister was watching me as she stroked her pussy softly several times. Once the condom was on I lowered my body to my sister's bed.

My sister, Mandy, turned around positioning herself on her knees and supporting her weight with her hands against the mattress. From behind, I remembered my sister had said that was her favorite sexual position. A Brazilian girl I knew had once called this position "on all fours". It wasn't some random girl I was with now but my sister spread on all fours naked in front of me waiting for my cock. My sister who had teased me growing up, my sister who had helped me with my home work, my sister who I wasn't supposed to ever touch in a sexual way.

I slid closer to my sister on the mattress, my groin, my cock touching my sister's ass, resting against her butt cheeks. My sister turned her head back towards me looking at her naked brother, feeling her brother's cock against her ass, at the gates of her sex. "This is too weird. Being in this position with my brother, I don't know if I can do this." This was my fear, my sister stopping. Please she can't stop now.

I pleaded to my sister, "Relax, relax. I'm Brian you've done this with him many times before. Just relax, concentrate on your hottest fantasy. Believe that's what's happening now." I wasn't sure if anything I said made any sense but my sister turned around she let her head fall close to the mattress. My sister seemed to be trying to distance her head, her mind, from the rest of her body, from her pussy.

I grabbed my cock and placed it between my sister's legs. The head than shaft of my cock slid through my sister's pussy lips. My sister moaned softly, "Ahh". For someone who wasn't sure she wanted to go through with having sex with her brother, my sister's pussy was so wet. My cock was now wet with my sister's pussy juices. I pulled my cock back towards my sister's opening. Holding my cock I placed my dick against her hole. Slowly I slid my cock through my sister's wet pussy lips into her soaked vagina. My sister's vaginal walls surrounding my dick, her brother's cock.

I couldn't believe I was pushing my cock into my doctor, priss sister's pussy. "Ahh ooo god," my sister moaned. I probed my cock in about half way into my sister's pussy. God she was wet. I started to withdraw my cock nearly to her entrance and than I pushed forcefully back into my sister's vagina. On the next stroke my cock was fully submerged in my sister's pussy. "Ohh. " I didn't want to speak or say anything that might stop my sister from fucking me so the next words just escaped my lips. "My god your pussy feels good, sis."

I moved my hands to my sister's hips and started to fuck her slowly. My sister's head was still hung low close to the mattress. My sister softly moaned, MMMmmmmm," almost continuously as I fucked her. After a couple of minutes of slow fucking I started to increase my pace. It had been so long since I had felt pussy, the texture, moisture, surrounding my cock, so long since I had felt a pussy besides Alyssa, my lost girlfriend. Now I was fucking Amanda, my sister. It felt so good, so different, my sister's pussy much tighter. My sister's body completely different than Alyssa's bony frame, more supple.

I was pounding into my sister's pussy stroke after stroke. The sound of fucking reverberating off the shell of the boat. Slam, slam bouncing back at us off the wall, flesh off flesh. Cock and pussy. My sister groaned, "That's it fuck my pussy, baby, Fuck me baby. Ohh my God I needed cock, your cock feels so good. So full. Fuck, ooh fuck me like that. Ooh fuck me. Fuck mee, fuck meee, ahhhh" my sister groaned. I couldn't believe my goody, good sister was such a dirty talker during sex.

My sister's body glistening with moisture as sweat dripped off my face onto my sister's ass. The heat of the day and sex, the exertion of energy covering are bodies in sweat.

I loved hearing my sister's moans. Her groans of pleasure. My sister's sexual nature had always been locked away from me, her brother. I was finally understanding who my sister really was beneath the polished surface. Hearing her, feeling her, no brother is ever supposed to see his sister getting fucked like this let alone being the one fucking her. I was so turned on listening to her,

"Ohhh, god I love your cock, keeepp fucking meee, I'm going to come on your cock. Keep fucking me." My sister's voice sounding completely different while getting fucked, sexual, wanton and deeper. I knew I was never supposed to hear my sister's sex talk or getting fucked voice.

I knew I was fucking my sister, maybe the greatest moment in my life I realized even as the act was going on. My greatest accomplishment. I had told my sister to fantasize whatever she wanted while I was fucking her. But when my sister moaned, "Ohh Brian, Brian," I was pissed off. I wanted my sister to moan my name, her brother's name not some soft dicked boyfriend of hers. She was going to dump Brian, he never had the time to fuck my sister. A god damn crime.

I took my hands off my sister's hips and leaned forward kissing her sweaty back and rubbing her side. I placed both of my hands underneath her grabbing her breast, such big tits. Squeezing her nipples, "Oohh my pussy right to my pussy, nipples." I pinched her nipples again. The front of my sweat covered body was now meshed against my sister's back as my hips continued to thrust my cock into my sister as deep and hard as I could. My sister pushed back at me slightly with her ass. I moved my head close to her ear as my sister moaned. "Fuck me baby, fuck me hard, that's it. I love cock."

I whispered into my sister's ear, "Your fucking your brother, my sister has my cock in her pussy. Her brother's cock. I'm fucking my sister, Amanda, Ohh Mandy, my sister's pussy."

My sister stopped her moaning as her mind raced. I grunted out, "Who's fucking you, who fucking you sis?"

"No, no Brian," my sister groaned.

I stuffed my cock back into my sister again and again. "Who sis, should I stop, who sis? Mandy I want you to say my name. I want my sister to say my name as I fuck her."

"Nooo, wrong, so wronnggg," my sister moaned.

"Gavin, your brother is fucking you. You love your brother's cock. My sister is not a good girl. Good girls don't let their brothers fuck them. You're a dirty girl letting your brother put his cock in your pussy. Say my name, Say your brother's name, Say it." I pushed into my sister's pussy as forcefully as I could.

My sister smiled, "Ohh Gavin, Gavin, Gav, ohh my god I'm fucking my brother. My brother is fucking me, my brother is going to make me cummmm. Fuck my pussyyy, little brother. Fuck your sister. So close"

I pinched my sister's nipples hard, knowing that helped my sister cum. "Ohh god, so close, please please."

"Look at me Amanda, look at me sis, I want to see your face when you cum. Look at me, look at your brother while he fucks you. Sis, that nurse is here to watch you get fucked by your brother, look at me". I was pounding into my sister, I was so close, I couldn't hold out, I can't hold out, I could feel the cum building. But I tried holding back, my sister picked up and turned her head to look at me. Her eyes glazed, hair sweaty, I squeezed her breast and than her nipples. Immediately, my sister's pussy clenched, tightening against my cock. My sister's vagina spasming, her body stiffening than shivering, her eyes shutting than opening. My sister's face looked as if she was in agony for a second and then pleasure flooding her features. My cock blowing my load into the condom, there was no way I could stop from cumming after feeling my sister cum, seeing my sister's cum face. My sister's mouth was gaping open, as she wordlessly screamed than her lips softly saying, "incest, my brother."

I kissed my sister's mouth slipping my tongue against hers. I kissed my sister's cheek, rubbing against her for a second, "My sister is good fuck, dirty girl." I was breathless the exertion catching up with me, "remember what I said about Adam and Eve. Incest being natural," I breathed deeply again, I was so tired. "Total bull, I've wanted to fuck you since I first so that shaved pussy of yours, sis."

My sister opened her eyes, staring at me with a blank expression, totally lost. My sister lowered her head, overcome, drunk with her orgasm. My sister cums hard. Finally I could feel myself deflate slightly so I pulled my body off my sister and slowly slid my cock out of my sister's pussy. I reached down and pulled the condom off my dick and threw it on the ground. I was certain that I'd be fucking my sister again.

My sister was still kneeling on the bed "on all fours" her pussy close to my face. Mandy seemed to be transported to another world, or a sleep. I could see my sister's cum running out of her lips and down her thighs. I was so tired and so hot. I could barely breath. But I couldn't help myself I had to taste my sister's shaved pussy.

I had to eat my sister's pussy. I lowered my head and started licking her lips. I had never had bald pussy before. I was licking her lips tasting my sister's pussy juices, her cum. I forced my tongue into her pussy. Tongue fucking her. My sister moaned softly but still seemed to be not altogether there. I pushed my head in between my sister's legs and started licking and sucking on her clit. For few a second I finger fucked my sister as I licked her clit then I pulled my fingers out of her vagina and concentrated on her clit.

"OHH no more, Gavin. I can't take it." my sister said softly. I continued tonguing her clit, "Ohh my god your going to make me cum," my sister practically screaming. "you fuck, you fuck, ohhhh brother," my sister put her hand down and tried to push herself onto her legs. Slowly Mandy started to gather strength and her feet under her. I continued to lick her clit and then sucking down hard on it.

My head and mouth rising with her body. My sister was standing and I was on my knees eating her pussy and licking her clit. My hands were wrapped around on her stomach and hips trying to hold her in place. "you fucking bastard. Cummmm. Brother, making me cum again, bastard." My sister put her hand on my head and pushed her pussy into my mouth.

I ignored everything as I sucked and licked my sister's clit disregarding even breathing. "AHHHH, shouldn't, shouldn't , brother." My sister pushed her pussy against my mouth and pulled on my hair than let go. My sister reached back and pushed my hands off her hips and stomach. I gave her a last lick across her shaved pussy lips as she slowly moved on shaky legs away from me. My naked sister walked out the ship's cabin door.

I stood still for several minutes exhausted from the heat and effort. Catching my breath. It seemed as if I hadn't breathed in hours. I wiped my face with my arm. Wiping off most of my sister's pussy juices from my lips and face. Slowly, I stood on my wobbly legs and walked across the room to my mattress and than collapsed down. I slept for several hours. When I woke I put on my swim trunks and went for a swim. I searched the island for my sister but I couldn't find her.

I was a little worried that what we had done might be freaking my sister out. Getting fucked by her little brother might be too much for her morals. Cool and refreshed by my swim and with the temperature dropping with the sun's retreat I walked back to the ship stopping only to throw a few branches on the fire. My sister still hadn't returned. I figured she needed to be alone to come to terms with having sex with her brother. So I simply laid down on my mattress and relived the day. What a great day I thought.

A half hour later as the sun set and the light became dim I heard my sister enter the cabin. My sister was still nude but now dripping wet from what I presume was a swim in the ocean. My sister picked up the towel and dried her hair and then her body. My sister dropped the towel on the table. She looked over at me and saw me watching her. My sister made no move to cover up her nakedness, she continued to stare at me for several seconds. Mandy walked over to my mattress and then motioned with her hand for me to move over.

I slid over on the mattress as my sister laid down next to me. My sister cuddled into my body. I could feel her breast and nipples pressing against my stomach. My sister's face leaning against my side. Mandy reached up with her hand and started gently rubbing my chest. "I couldn't stop it, I didn't want to stop it. It was inevitable," my sister started rationalizing softly to me. "Seeing you every day, how brave you are, how handsome, your body, chest, abs, cock. God your cock. Day after day. Like a married couple living together. But with less clothes. Or no clothes. I tried to resist. For months I've tried to push thoughts about you out of my mind. I've wanted you for so long ," I just listened and let my sister talk it out.But I thought it was wrong. I was sick. Than you touched me. It felt so good it scared me. I was terrified. Then you said you wanted me, to fuck me. I figured we're both going crazy, crazy with horniness. Then seeing you playing with you penis," my sister using the proper medical term. "Staring at me while you touched yourself, asking me to touch myself. It was too much. I've wanted you inside me for so long, since we got to this island. I've been thinking about nothing else. No one could resist having sex that long, not over 60 days with a cute guy walking around practically naked day after day. I had to have you inside me even if you're my brother." My sister smiled, "Even Mom would have fucked you after a month on this island. I think I did good lasting over 2 months."

I smiled and responded, "Dad wouldn't have lasted a month. Dad would have been trying to get you in less than 30 days. I think I did good lasting over 45. Your so beautiful."

My sister answered, "Dad would have been trying to get inside me in less than a week. I catch him staring at me all the time, checking out my tits and ass, basically eye fucking me."

"Dirty old man. I thought you guys were close, both doctors and all," I quipped.

My sister rolled her eyes, "Sometimes I want to tell him go fuck Mom, she's hot and leave me alone. I'm your daughter for god sake not some slut nurse. Now I'll just tell him I like to fuck my brother, I'm not into dads."

"That'd be interesting."

My sister reached up and sucked on my nipples while squeezing my other nipple with her fingers. "I've never had sex with anyone like that. I've never cum like that, twice like that. I've cum with you three times, more than I've ever cum with a guy. My own brother. My own brother is 4th guy I fuck, fourth guy to see my cum face. My best sex before today was with myself, my fingers or vibrator. I can't believe my best sex is my brother." My sister reached down and started stroking my cock underneath my swim trunks.

"You know I heard you fucking Alyssa at the hotel. I was in the next room. I couldn't believe I was listening to my brother fuck some girl. I put a pillow over my head so I wouldn't have to listen. But when you started to fuck her a second time," my sister looked up at me shyly, playfully, "I decided if you can't beat them join them. I started playing with myself, rubbing my pussy while I listened to you, my brother fuck his girlfriend. At some point I started to fantasy it was me you were fucking."

"I couldn't believe I was thinking that at the time. I thought my little brother has a better sex life than me. I wondered what it would be like with him. I came thinking that, listening to you have sex with Alyssa, imagining it was me. I put my hand in my mouth so you wouldn't hear me scream as I came. I wore that thong on the boat to drive you crazy, like you drove me crazy that morning at the hotel. But you hardly noticed me, dad couldn't keep his eyes off my body, my ass, tits, my pussy but you hardly noticed your sister in her little, bitty bikini, thong, she had worn for her brother."

I reached down and rubbed my sister's breast, "I did notice, your gorgeous. I just didn't want to make a fool of myself staring at my sister." I reached on the floor next to my bed and grabbed a condom. I ripped open the wrapper. My sister was already pulling down my swim trunks. My sister forced my swim wear over my ass and then off my legs and feet.

"Let me," my sister took the condom from my hand and grabbed my dick. With one hand she held my hard cock steady and with the other she unraveled the condom down my shaft. My sister gave my cock one quick stroke and then let go. My sister started to turn to get on her knees so I could fuck her from behind again. I placed my hand on my sister's side and held her in place.

"I want to see your face, I want to see your face as I fuck you this time," I told my sister.

Mandy moved onto her back and spread her legs wide. Obscenely wide,. Her bald pussy graphically exposed to her lustful brother. My sister was smiling as I moved in between her legs. "Every brother and sister should get to know each other like this. Incest, my god incest with my little brother. Fuck me little brother. Fuck your sister's pussy." the ultimate taboo, the ultimate aphrodisiac. I slid closer to my sister, lining up my cock. The tip of my cock touching her wet pussy lips and than I was pushing into my sister's pussy. "God I love cock, my brother's cock" my sister moaned. "MMmmm, perfect fit, my brother's cock, my pussy. Ahhh, Every sister, ahh sister should try their, their brother's cock." My sister spoke in her deep, gutter like sex voice. "Fuuu, fuckkk your sister with that cock."

I smiled down at my sister as she enjoyed my cock pushing in and out of her love hole, "My sister's pussy, sister pussy. Every brother wants to stick his cock inside his sister's pussy. I'm, ahh I'm," I caught my breath, "one of the luck few to do it." Incest is beautiful."

Day 85

The last 19 days had been the greatest time of my life. My sister and I spent our days enjoying each other's company and bodies. My sister was far wilder than I had ever imagined. My sister was a horny woman. My sister fucked her brother, me, on average twice a day. A couple of days my sister was too sore from me fucking her too hard. On those days Mandy would give me a loving blow job that only a sister can perform while I ate her pussy. We had sex in every imaginable position and place on the island. Under the waterfall, in the ocean, on the beach, in the forest, on the raft, from behind, missionary, her on top, reverse cow girl, 69, standing up, and many others. My sister and I had grown incredibly close, from partners fighting for survival to incestual lovers to a couple.

The wind had been whipping during the night so I got up early to check on the raft. I wasn't sure if my sister ever planned on leaving the island now but I wanted to maintain the option. I was happy where we were. I knew if we were ever rescued or used the raft to escape the island our relationship would change back in the real world. My sister had insisted on that condition only a couple of weeks ago. Had things changed for her? My sister had also said that no matter what we were using the raft to get off the island at the 6 month mark of our stay. Did she still feel the same about that as well?

I guess time answers most questions. I decided to enjoy my sister's body for the next 3 plus months and see what happened then. Carpe diem.

I was walking back to the ship when I saw my sister sauntering towards me carrying the towel. My sister was topless, only wearing her tan thong. My sister and I had spent the last two weeks naked about 80 percent of the time. This was the most clothes I had seen her in days. Way too much clothes I thought, but she had told me she was worried about her pussy lips getting sun burnt. My sister's thong only covered her pussy lips and not much more but I immediately wanted to yank it off her and start eating her pussy. I was wearing my swim trunks.

"Hey little brother, you got up way too early. I was lonely. I need my morning loving," my sister coyly played.

"I wanted to check on the raft. Make sure nothing fell on the boat."

My sister looked out at water, "Are you in mood?"

"For what?" I asked already knowing the answer.

"To make love to your sister, little brother, I need you at least twice a day," my sister teased.

"Always," I leaned forward and wrapped my lips around my sister's nipple. Licking her nipple with my tongue as my right hand squeezed my sister's breast than I squezzed her nipple. My left hand went to my sister's pussy and started to rub her clit through the thong.

"AAhh baby, you know, you know what I like, you like my tits don't you little brother.." I moved my hands to my sister's bathing suit and hooked my thumbs into the material. I pulled down my sister's thong over her ass and then down her thighs. I sucked hard on my sister's other nipple as my left hand cupped my sister's wet pussy. "Make love to me, please, I need your cock, please" my sister moaned. I pulled my mouth away from her breast and my hand from between my sister's crotch. There is nothing like hearing your sister beg for her brother's cock to get your attention.

My sister stepped out of her panties as I pulled down my swim suit leaving it in the sand. My sister spread the towel on the beach. "I forgot, we ran out of condoms yesterday. Should we do this?" I asked.

"I know, I did the math, we can have sex for the next 7 days than we have to take a break for a few days," my sister looked at me shyly as she lowered her body onto the towel. "But we can do other things, you know. I can't live without your cock, no way. I'm a doctor trust me. I won't get pregnant. I won't make you a daddy, and an uncle. Ehhhh, that's too strange to think about, it's going to be fine. This is human physiology 101. I got an A in that."

"I trust you," I told my sister. I kneeled down behind Mandy as she moved into her favorite position, "on all fours" as my sister watched the ocean from the beach. "I have to rate my sister's body A plus." I looked out over the ocean. "Can you believe how calm the ocean looks, so different from when we were out there on the boat. The wind and currents bringing us here."

My sister stared out at the water, "I love the ocean, if it wasn't for the ocean we would never have gotten together. I would have lived my life never knowing what it was like to make love to you, my brother. I would have married Brian, had boring sex, saved some lives which is a positive, but lived under constant stress. Do you think we'd have gotten together, if things had been different, no storm?"

"Not a chance," I quickly answered with certainty. "The real world had us both so programmed that I never would have considered it. If I ever tried making a move, anything sexual towards you, you would have told mom and dad or the cops."

"Your right," my sister speaking to the ocean, "Thank you, thank you, for the greatest sex of my life. I've never cum so much, been so happy.."

I moved closer to my sister and kissed her back. I lowered my stiff rod to my sister wet lips and slid inside her. My sister's pussy felt even better without a condom, slick, tight and warm. I pulled partly back and than pushed back into her vagina, bottoming out. My sister's and my genitals pressed against each other. "Fuck, fuck ahh what we would have missed." The taboo of making love to my sister had faded some after 19 days of intense fucking. My sister was beautiful both physically and inside. The first time I had fucked my sister but the sex had turned into love making.

My sister and I had developed a rhythm to our sex. I started pistoning in and out of her pussy. She was so wet. I could feel her using her pussy muscles more and more as she tried to squeeze my cock. I looked down between us, my sister's shaved pussy, my cock disappearing inside her. So beautiful to watch my cock move in and out of my sister.

My sister started moaning "Ahhh, ahh, god I love your cock, my brother's cock, no one can fuck a girl like her brother." My sister knew I loved it when she talked dirty. I started fucking my sister harder, god I loved the sound of my body hitting hers combined with the slushing sound of wet pussy and cock. "Only dirty, dirty girls let their brother's fuck them" my sister grunted. "What a shame, what a shame, missing, missing, so much, so good, brothers are so good."

My hands were wrapped around my sister stomach as I used her body for leverage to fuck her harder. "Ahh babbby, bbaby brother, fuck me fuckkk mee." I looked up at my sister who's head was down close to the towel as I scanned the ocean. My sister continued her moaning, "oohh god, ohh make me cum." That can't be I thought to myself, it's an optical illusion I thought. A boat had pulled into the harbor and was anchored off shore. I continued fucking my sister as I moved my hands to her hips as I pulled my self upright looking out at the ocean. I saw people moving on deck and the flash of glass, binoculars? Two people looking at the beach with binoculars, watching me fuck my sister. Rescuing us?

Stunned, I didn't stop fucking my sister, my cock and hips were on automatic as I slid through her silk sheave. God my sister's pussy felt good, the taboo of fucking my sister rushing back at me from society. Making the sex better than ever before, more wrong, people were watching me fuck my sister. I needed to tell Mandy, my sister. It was only right.

My cock pounding into my sister stroke after stroke, the glasses still flashing on the ship's deck as strangers watched our incestual sex. I leaned down pressing my body against my sister's back. I reached beneath my sister and cupped her soft, silky breast. Squeezing her nipples.

"Ahh my nips, love that, pinch them, pinch my nipples, right to my pussy." I pinched my sister's nipples again. "make me cum, cumm, please."

My mouth next to my sister's ear I whispered, "Mandy," my sister had her eyes closed tightly, "Amanda."

My sister opened her eyes and turned her head to look at me, "Watch me cum, so close."

My sister staring at me with an agonized expression, breathless I said, "Look there's a boat, boat out on the ocean, rescue. Watching us fuck."

My sister stunned turned her head and looked out at the water, "Ohh my god."

I continued to thrust my cock in and out of my sister's pussy, never stopping. Stroke after stroke. "Should we stop?"

My sister replied immediately staring into my eyes, "Nooo, noo don't stop, keeep fuccking, ahh meee. So close, let, let ahh watch. Who carrres," then my sister turned her head towards the water calling out loudly but not loud enough to be heard, "Goo away, ahhh, my brother's fucking me, don't resucue, now, go away. I want to cum on my brother's cock. Fuckkk, fuck go, go go. Llleave us alone. Can't give him up, never, never give up his cock."

My sister and I watched as two people got into a small boat and started towards shore, "I think we better stop, sis. There coming."

"Noo, I'm too close, please, please don't stop. Brother fuck your sister. Fuck me."

The small boat was powered by small outboard engine and moved quickly towards shore. Our bodies joined as one as the outside world intruded on our love making. I kept fucking my sister. I said to her as I saw the binoculars raised again, "There watching us fuck, your fucking your brother, sis. I know you love people watching you fuck, they're watching you fuck your brother."

Suddenly, My sister raised her body as she stared out at the craft coming a shore. My sister had lifted both of her hands off the ground. My hands slipped off her breast to her ribs directly beneath her boobs. Her breast now totally exposed to the people in the boat who were both watching us through binoculars.

"Ohh my god, noo, no so wrong, can't beee them noo, ahhh keep fucking me little brother." I slowed my pace as my gentals hit my sister's genitals lightly. "Harder, make me cumm litllle brother, I want to cumm in front of them, don't stop. Hurry. Harder." My sister dropped her body back down and her left hand balanced her weight. I slid my hands back up to my sister's breast and squeezed her tits and started pounding my cock into her pussy with increased force.

My sister reached up with her right hand and placed it over my hand which was cupping her breast, "it's them. Mom and Dad, their watching us fuck, it's them, ahhh, my god their watching me fuck my brother." I pinched both my sister's nipples hard.

"No, impossible, their gone," I squinted my eyes, could it be mom and dad?

"Mommy, daddy, Gavin's fucking me, I love the way my brother fuck's me," the launch was almost at the shore no, my sister's voice might even be heard by the people on board. "Your son has the best cock, good job making my brother for me, his sister loves his cock, he fucks me so good, I'm going to cum, watch my brother make me cum. Mommy, Daddy, I want you to see my cum face. See my tits, mom, daddy loves my tits, see us cum together.

My sister had gone insane. Ohh my god, she's right, my sister's right, our parents our watching their children fuck, their watching me fuck their daughter, my sister. Their son, her brother. "Don't stop they've already seen us, keep going, keeping fucking me little brother. Mommy, daddy wants to fuck me. Mommy, daddy wants to put his cock in my pussy, his daughter's pussy. I know he does, but I won't let him, my pussy is for my brother, my brother's cock only. Mommy, daddy, watch us fuck, please, please."

Our parents were now only twenty feet away. I was turned on by my sister's words, scared at what was happening. I pushed into my sister's vagina, trying to cum, make her cum. This is insane. I fucked her harder than ever before. I was a fucking machine. Sick perverted little brother fucking his sister. The sound of fucking echoing everywhere, down to my parents at the shore line.

"Ohh, my god, daddy, mommy, ahh, I'm cummming, my god your watching me cumm, your daughter with my brother ahhhh noono, my parents watching, should 't be seeing this, doing this with my brother. Ahhh so good, he's so good" I pinched my sister's nipples hard, than pinched her nips again. I could feel her pussy immediately grab my cock, squeezing the cum out of me as I shot my load into my sister's taboo pussy as she spasmed beneath me. I had never cum so hard in my life.

"Ahhh babby, babby brother your cumming in me, no protection, mommy daddy, Gavin's cumming in my pussy. Ahh, I can feel his cum inside my pussy. My brother's cum is in my pussy, his sister's. Ahhh yes, you've watched us fuck, our parents. Your children fuck each other's brains out. I'm his sister, my brother. Incest is best, the best."

My hips were still on automatic as I continued to thrust my cock deep into my sister's pussy. I said too loudly, "Fucck, your good sis, best pussy, best sex, with my sister." I looked at my parent as they moved towards us. My hips stopped thrusting my cock into my sister's love hole.

My sister who normally practically passed out after she came started crawling forward. My cock slipped out of her pussy. "Ahh, ahh." my sister moaned. My sister, Amanda, put her hands down and pushed herself up on incredibly shaky legs. My parents were 15 feet away and walked forward a couple of steps. My sister was standing naked in front of my parents. My sister tentatively raised her hand to gesture hello. My mom was dressed in a sexy white bikini cut high on her leg. My dad looking distinguished with his salt and pepper hair was wearing kaki shorts and blue collared shirt. They stopped 10 feet away from my sister.

I was still on my knees and my cock still hard. I stared up at my sister tight ass from behind and in between her legs. I could see my sister's pussy juices, her cum and my cum, her brother's cum, leaking out of her shaved, bald pussy. A sibling concoction of juices. Her thighs, pussy lips wet with our fluids.

My mom and dad standing there looking at their naked daughter. My dad a pillar of the community, a doctor, a surgeon. My mom, a country club diva, judging the world on morality. My sister's huge d cup breast, her gigantic areolas and hard nipples. They stood their staring, not believing what they had seen their children doing. Fucking, committing incest. The biggest taboo.

I could see my dad eyeing my sister, especially her tits, than his eyes moved down to his daughter's pussy. His daughter's pussy which he had been desperate to see for years. At last her dad could see his daughter's shaved pussy. Our father could see the cum leaking out of his daughter's taboo pussy hole. My dad who secretly lusted after his daughter's body. Checking out his daughter every chance he could, eye fucking his daughter. My dad watched his son's cum leak out of his daughter's taboo pussy. The taboo hole that he yearned to fill with his fatherly cock, but knew it was wrong, immoral and illegal. Society keeping him in check. His son, her brother, had put his cock in his daughter, the taboo hole where her dad had lusted to enter. Not Incest with him, her father, but his son. Incest. His daughter had fucked her brother, his son's cum mixing with his beautiful daughter's pussy juices.My mom's eyes followed my father's eyes down in between my sister's legs. Horrified, she viewed the product of her children's love making. Brother and sister. Her children's cum, her son's sperm leaking out of her daughter's pussy. Cum running down her daughter's thighs, droplets leaking from her daughter's special and most sacred place onto the sand. So wrong, so awful. I could hear my mom say out load what she was thinking, "Oh my god no. No" as she stared in between her daughter's legs, the place where her son's cock had been moments before.

My mom's mouth was wide with shock as she placed her hand to her lips. My sister followed her parents eyes and knew they could see her pussy leaking cum. Ashamed, embarrassed, my sister turned and bent down to the ground and picked up her thong. My sister giving her mom and dad another angle of her body, her back, ass, asshole and pussy with her legs and hole wet with brother and sister cum. My sister looked me in the eye for a second. Anger, fear, disbelief but mostly shock. My sister with her thong in hand ran off nude in the direction of the ship.

My parents could now clearly see me kneeling on the towel. I slowly stood up and felt incredibly naked. My cock was still hard. The shaft and head of my dick glistened with my sister's pussy juices and my cum. My parents looked at me, the good for nothing son who had corrupted their beautiful, perfect, doctor daughter. For a second I saw their eyes scan the cock that had made their daughter orgasm. I turned giving my parents a view of my ass, and reached down to grab my swim trunks. I quickly pulled on my shorts and turned back to face the consequences of fucking my sister, my mom and dad. My mom lowered her hand from her still gapping mouth speaking, "Your alive, nothing else matter, nothing you've done matters, my children are alive. I love you, I love you both so much."

My mom moved towards me, her nipples poking against the fabric, her bikini bottoms wet at the crotch, from jumping into the water, or from watching her children fuck? My Mom hugged me tightly and then I saw my father move towards us, is he hard? "She's right, your alive, what you've done to survive doesn't matter. It's our fault, my fault for not finding you sooner. My dad hugged my mom and wrapped an arm around me.

My sister came running towards the beach, "Momm, dadd,"my sister shouted. My sister's was wearing her tan thronged bikini that my mom rightfully disapproved of. The small top barely covering her poked out nipples and bottoms covering her pussy lips and not much else of her mound. Mom was right she shouldn't wear a swim suit like that around her dad and especially her bad little brother. I could see a large wet spot in between my sister's legs where gravity was pooling our cum.

My sister ran up to us and hugged my mom and my dad patted her head. I wrapped my arm around my sister's waist. A group family hug. Beautiful. Full of love. I moved my hand down to my sister's ass and felt the strip of fabric running between her cheeks. I glided my hand over both of her cheeks, squeezing her butt several times. So familiar now. I lowered my hand and started rubbing my sister sex in between her legs. Feeling the wet spot in my hand. My sister broke off the family hug pulling away from me. My hand sliding out from between my sister's legs, off her pussy. My sister beaming, smiling at every one. My sister, Mandy, stated enthusiastically, "We're rescued."
