15m turned my cousin into a tranny

We were both 15. We'd been playing around and touching each others cocks for a few years but nothing more than a little grab ass. His parents were taking a vacation taking his 14 year old sister with them. They were leaving him in the house, but only if I stayed with him. My mom and a mutual aunt lived very close by in case of a major problem. He and I stayed in the double bed in his sisters room, she took his single. This was the night before his parents left. It was that night that I first got off with him. I moved in next to him, feeling his ripe, beautiful ass cheeks. Then I pulled his underpants down in the back rubbing his naked globes with my hand. I pushed up against him with my underwear down in the front. My thick 7 inches was rock hard as I spooned into that wonderful crack of his ass. I started moving in it, going up and down. He got up and said wait a minute. He went to his dresser and brought over some hand lotion and rubbed it between his ass cheeks. Seeing that perfectly shaped rear in the moonlight got me even harder than I thought I could ever be. He came back taking his undies off totally and spooned back into me. He reached back giving my cock a couple of strokes to get the remnants of the lotion off his hand and onto me. Then he pulled me back into the crack. I guess it took me 10 minutes to cum. That was 10 minutes of whispers between us, pulling his waist to get him even further back to me. At the end I rolled him over on his stomach and on top of him I shot a massive load onto his back and my stomach. After I got myself together more and got off him, he went to the toilet down the hall, still naked with my cum running down his back. I couldn't believe he'd do that, he could be caught by someone. He brought back a washcloth, wiped my cock and belly and pubes of my cum, then his lower back and ass. Still naked he took the cloth back to the bathroom.

In the morning we got up early, helped load up the car with the suitcases and they were off. We went back in and we stopped at his sisters room again. "Do you want to do it again?" he asked. Hell yes I wanted to cum again, I was a 15 year old boy. This time we used the lotion and I reached around while I was doing it and jacked his cock. I pulled up so the whole load went onto his ass, I pulled back and aimed some directly at his asshole holding my cock right at his hole. He pushed back and about half the head of my cock went into his ass with my cum as lube. "Mmmmm, that's nice" he said. We got up, cleaned up I got dressed and he was in the room still. When he came out he was wearing one of his sisters skirts, a blouse, stockings and shoes. His long blonde hair was parted in the middle and went down to his shoulders. He looked different, it was lipstick and some makeup. He didn't say anything about the dress, just asked what I wanted for breakfast and while cooking for us, he asked if I was OK with what we'd just done and did the night before. I said I was loving it, and he said after breakfast and him washing the dishes, he'd put on some laundry and we can have the whole day to do whatever we wanted. When I said "Watch saying whatever, you might get something you don't necessarily want". He came to my chair, sat on my lap and told me "I want it all, for you, you can do anything you want" then gave my cock a squeeze through my pants. I was amazed, he brought me coffee, then did laundry and came back on the couch sitting on my lap.

I took off his dress and his blouse, he was in stockings, panties and a matching bra. "Do you need these?" I asked as I was playing with the waistband of his panties. "No" he said and I stripped naked and brought him on my lap. We were close, our lips inches away from each other. "I liked it when your thing started going into me this morning" he whispered. "Me too" I said and pushed my cock to his asshole while he was seated on my lap, then he moved in and we kissed. Breaking off he said that he didn't want his first time like this, and took me to the bedroom. there in his bra, and stockings using the lotion, I fucked him. I stuck my cock in his ass and came in it. All the while I was kissing his neck his ears even moving to his lips as I was cumming.

We spent the week with him as my girl, and me as his man. I fucked him, made him suck me. He didn't want to do that but I wouldn't let it go, so I not only made him suck me I made him take the cum and show me, then swallow. At night he'd wear some of his moms super sexy lingerie. We had a wonderful 2 weeks. I probably fucked him 30 times during that period, he was always willing and available. We fucked in the bedroom, in his single bed, in his mom and dads bed, in the kitchen, living room, even one night went out to the back yard and fucked under the stars. He and I liked missionary best and that was the way we fucked the morning his parents and sister came back.
