There is no way to confess to this without just saying it, my first time was with my cousin. Not a cousin by marriage, not a second or third cousin, full blood relative cousin. We're the same age and have always been pretty close for cousins that don't see each other very often. We were 15 when it happened.
The whole family was together for a wedding. We snuck off to her room with a bottle of wine from my uncles basement. He made his own wine and had about 30 bottles, we thought he wouldn't notice.
In about fifteen minutes, the bottle was half empty and we were both getting pretty wasted. It was hot in her room, so we stripped down a to our underwear. I was transfixed by her boobs, I think she was a C cup at the time, and I immediately popped a boner. She was pretending not to notice but I could see where she was staring. Apparently the wine was making us horny too.
We got to talking about how far we'd gotten with the other gender. I admitted I was a virgin and after mocking me a little, it's just what we do, She admitted she was a virgin too. She said she wanted to try sucking a boys dick. I jokingly said she could suck mine but we were cousins. She said she didn't care, that she just wanted to try it. I was too drunk and horny to say no.
So, laying back on her bed, she pulled down my boxers and my cock popped free. She stroked it a few times with a smirk before she put it in her mouth. It was clearly her first time, my dick was too big for her and it kept grinding against her front teeth. She kept me hard but I couldn't cum. After quite a while of her edging me, she gave up trying to get me to cum. She asked if I wanted to try anything. I was still fascinated by her boobs so I asked if I could touch them. She giggled and said okay. She took off her bra and I finally got to see boobs in the flesh. She has some of the biggest areolas I've ever seen, probably four inches across, that's so sexy! I pounced on her and push her some what gently to the bed as I begin sucking on one of her nipples and begin fondling her other breast. A soft, heavy mass of pure pleasure. Out of no where, she confessed I was her first crush which caught me a bit off guard, but I told her the truth that I've had a crush on her since I was 10. It wasn't long before we decided, since neither of us had cum and we were both beyond the point of turning back, to lose our virginities together. She laid back on the bed and spread her legs. Her pussy was wet and as I rubbed her with my cock, she giggled. She said she couldn't believe she wasn't going to be a virgin tomorrow. She was so tight and as I pushed through her hymen, she cried out a little. I asked if she wanted me to slow down and she said no. She locked me in with her legs so I didn't hold back. I began thrusting into her and her cries turned to moans. She began telling me to go harder and faster. When she started dirty talking, my 15 year old balls couldn't take it and I told her I was cumming. She moaned that she wanted to taste my cum but it was too late for me to pull out. I came hard into her pussy. I had never cum that hard in my life. I remember thinking sex was literally the best feeling ever. After a minute of lying there, she looked at me, kind of disappointed, and restated she wanted to taste my cum. I told her I was out. She started rubbing my cock with her tits and asking if I was sure. While I did want to get hard again for more fun, even I was surprised I did. I asked her to lay on her back and press her boobs together. Then I titty fucked her. Her hot, sweaty breasts felt amazing. I felt myself cumming and this time, there was no way I could miss. I pulled out, put my cock in her mouth and shot my hot load straight into her mouth. She held it in her mouth for quite awhile before swallowing. She admitted to not liking the taste and apologised for making such a fuss. We laughed and fondled each other a bit more before passing out.
We were both hungover in the morning. The parents quickly caught on and found the empty wine bottle in her room. We got a stern talking to and we both got grounded. We got off lucky, if they had known what else we had done in that room last night, I'm not sure what they would have done.
We share looks when our eyes meet. I know we were both thinking about it because that's not the only time we've done it, but that's a whole different story to confess to.
