It happened earlier this summer, but I've been stalking this sub forever, so I wanted to share my story too.

I (18f) was visiting some extended family on the other side of the country over the summer. As always, I was sharing a room with my cousin sister (20f). We've always been super close, and I've always had a small crush on her. She is gorgeous, with waist-length dark hair, olive skin, slender fingers, and wonderful perky C-cup breasts.

It was the middle of the night, and we were goofing off in her bedroom, drinking a couple of bottles of soju. The conversation flowed to us talking about sex. She had just recently broken up with her boyfriend and was talking about how bad he was at giving her head, so I joked that she'd probably be much more satisfied sleeping with a girl.

She perked up, and started asking me a million questions about what it feels like to be with a girl. She was raised a little more sheltered than me (her side of the family were better Catholics), so she was really curious about what lesbian sex feels like, how you do it, and how many girls I'd been with. What caught me off guard, though, was the night ending with her saying, "You sound like a better lay than [her boyfriend] right about now." Unsure of what to do, I just laughed it off.

She eventually kissed my cheek, wished me good night, then turned around and drifted off to sleep. What she said had made my pulse race. Alcohol always made me horny, and considering how pent up I was—after days on the road and little alone time—my vulva was almost screaming to be touched. My cousin's sex talk had really got me going, not to mention how hot she looked that night. She had been wearing a low tank top with just a pair of boyshorts underneath, giving me a great view of her butt.

The soju definitely made me more brazen than I would've been otherwise, so I slowly slipped off my underwear as quietly as I could and started rubbing myself under her covers. I was picturing myself eating my cousin out—giving her a better time than her ex-boyfriend ever did—cupping her soft thighs as I pleasured her with my mouth and fingers.

I was dribbling honey, fighting back moans as I rubbed myself to my sleeping cousin. As dirty as I felt, I almost wanted her to wake up. I wanted to be caught. Unfortunately, real life isn't a porno, and she did not make any moves on me while I masturbated right next to her. I eventually came hard in just a few minutes, the taboo of the situation making me shake with an orgasm.

The moment-after felt really weird though. It wasn't my first time doing something taboo, but it was the first time that I truly acted on my incestuous fantasies. She stirred a bit while I got off the bed to clean my mess, but she made no mention of anything the next morning, so I think I got away with it scot-free.

All said, I really, really hope she isn't reading this right now. I hope you enjoyed this, you perverts :)
