Here is some of the material from that board.

I can't remember if I've told this story on here or another chan, but here goes.

When I was 17, me and my female cousin had a kinda flirty thing going. It had been going on for a year or so, we would make long phone calls to each other, write letters to each other (this was '97-'98, and we lived in different states), and generally get real lovey-dovey when we were near each other in person. We had this great connection, and we'd have long, deep conversations about anything and everything. Finally, one summer me and my family stayed for two weeks at her place. One night me and her were the only ones still up, and we were talking about dating and relationships. She confessed that she found me totally attractive and if we weren't cousins, she'd totally date me. I confessed the same. It was a bit awkward at first, but I asked her if she wanted to make out, and she agreed. We made out for over an hour, I sucked on her tits, and we stopped short of anything else, because she didn't want to go all the way. Still, it was awesome. For the next week and a half we had a mini-relationship going; me and her would run off alone into the woods, hold hands and make out for hours. Finally, on the last night, after much insistence and pleading on my part, she finally blew me, but it was awkward and not that fun (it was the first blowjob for both of us). Afterwords, she was kind of quiet and weird, and I could tell she felt really bad about it. In retrospect I shouldn't have pushed her so hard.

The next day we said our goodbyes, and my family left. From then on, she was very distant, I would call her and she wouldn't answer, or would have some excuse why she could only talk for a bit. We eventually stopped talking, and a month later she moved away to a different state for college. I ended up not seeing her for three years, and we rarely talked. Finally after college we had a sit-down, and she said what we did was wrong, and I disagreed but I did apologize for pressuring her. We're semi-close now, and we talk every now and then, but it's nowhere near what it used to be.

That being said, I've always found incest totally hot, and I can see why it gets a bad rap, but I figure if you're both consenting adults, go for it.

Quid pro quo, OP. What's your story?

So I Finally got my cousin after a club night out, she is a hot as fuck half thai half spainish girl. Anyway, so we get wasted at the club and even grind and dance together before stumbling out like at 2am (cause clubs on the west coast suck) and I drunk drive back to my place with her. the whole time we are yammering on about who'd we want to fuck in that club.
So my place is one bed one bath kinda deal and she is completely wasted while Im sobering up but not enough to stop this liquid courage running through my cock.
Lights off, Sleep time. But she crashed on my bed first and Im not sleeping on my own damn couch.

I had managed to get into my white T and boxers and she just took her bra off and left her stretchy dress on. So my cock is at full fucking mast and she isn't totally asleep so lust gets the better of me and my fingers creeped across her bare shoulders and I just asked as sly as a drunk can what exactly would she have done with whomever she was gonna fuck. She, being the sarcastic bitch she can be, snorted and said something like "uhh Fuck him?!?" I responded with I think its hot when she says fuck, she gave some snort remark "oh yeah?" and we shared a laugh and I started saying how much a jerk she was to men and she shoots right back with all sorts of shit.

In the mean time down below the sheets my arm is now firmly under her neck (since she is turned away) and my other free hand had freed my cock from the fly of my boxers and started caressing her bare thigh.
So, some more flirtatious insults along with her shifting closer let her feel the full heat of my dick against her bare thigh. At this point the conversation just drops to dead silence.
Then we started ever so so slowely rocking back and forth, her thigh and my hips. the hand she had on top of mine on her thigh just lowers enough to get her pinky to barely touch the crown of my dick. And then another finger makes contact, and another. all while this is happening my heart is beating through my chest, like I could feel it pulsing my head. my left hand, the one resting on her thigh, had started to hike up her dress and move towards her inner thigh and i got all the way to where I could feel her the inner seam of her thong.

All I could hear was my fucking heart beat and her breathing, but her hand was on my cock, no fucking way she could have not known what it was. I flexed myself right into her palm and she sort of grasped it all the while my fingers started doing traces up and down that inseam and I finally got my index finger on the inside of that thong.

She totally shifted from on her side facing away to on her back so im staring directly at her face, but its damn dark and even with the street lights filtering in I couldn't see all too well, she was looking at me though or at least her head was facing me.

When she turned over her hand fell fully down my cock and she griped it, No denying that now. My hand was still working beneath that thong and my fingers found her folds. She was wet, like slick, and soaking wet. I played with her clit by moving that thong to the side and just lightly rubbing it with both fingers and when I heard her exhale sharply I let my hand go lower and put my middle finger inside her.

I was rough, I damn near picked her up with that hand thrusting, she didn't gasp, she MOANED! she squeezed my dick with her hand and started stroking while arching her back into my bed. All this was going down and I had to get in her, there was nothing that could stop that.

I pulled my hand out of her and rolled ontop of her pulling my shirt off and boxers down letting my cock slap my stomach hard, she spread her legs open and propped herself up on her elbows looking right at my cock.

I didn't say anything, I just kept her thong to one side with my hand and let the crown slip past her folds and anykind of defense her body had. Both of us let out a satisfied groan as I put my cock deep into her.

my hands found hers and I pressed her into the bed while my hips gave her the deepest hardest thrust I have ever given. She started to moan and gasp and roll her head from side to side as I thrusted my cock into her. she pulled her legs up around my waist and all I could hear besides her begging for it was the sound of our skin slapping. I kept at that pace forever. when I heard her moans get more frantic I started to pace myself and hit her with some fast deep ones and she pulled me close and actually bit me on my shoulder when she screamed just one word, "Cumming". she squeezed me so tight I tried to thrust more but she frantically said "too much! too much" I swear for the better part of a minute she was convulsing around my dick harder then I had ever felt a woman before. But she had hers, and now it was my turn, I pulled up out of her grip and started to gyrate my thrusts into her at a jackrabbit pace. She started to exhale so sharply out her clenched teeth repeating "Ahh! yeah! Ahh!" I fucking lost it. I gave Her one last hard push into her and my cock let onces and onces of greasy ropes of cum into her. I kept pushing into her until I was spent and just collapsed on her.

She was tracing circles on my bare back when I had enough strength to acutally push myself up onto my arms again. I can't be sure but I think she was smiling when she said "jerk". When I rolled over, we both gave an intense "uH!" when my cock pulled out of her folds. I grabbed her hand and thats how we lay in bed until I just passed out from exhaustion.

here we go. thats her. As awkward as the next morning was, that night wasn't our last. We had a close call during our next time as we were raised catholic and bc isn't approved of. We totally didnt realize the gravity of the situation described above until the next week but she got her period at the end of it so collective relief.

Please, if you acutally did do something, the whole point of the thread was i just wanted to know if anyone else out there actually had something similar happen to them
