My sister brought her nineteen year old boyfriend Brad round two weeks ago. He wasn't planning on staying over, so when my sister and he left it late, she asked our parents if he could sleep over. They being a little old fashioned said he could, but he'd have to sleep in my room.
Sharing my bed, I quickly went off to sleep and was sound asleep when I was awoken by the feeling off a warm wet mouth sucking on my cock. You know when you're not fully awake, eyes stil closed and everything still seems like a dream, that's what I was like. Yet the feeling surrounding my cock was getting more and more intense.
I'd totally forgotten Brad was staying over, and I didn't at first put two and two together. Then I felt my balls being sucked in and my waking state became clearer. Everything that I thought about myself as a straight guy went out of the window over the next half an hour, as I allowed Brad to continue to suck me off. It felt way better than any girlfriend I'd ever had suck on my cock, so I let him get on with it. Only Brad wanted more.
My dick was fully erect and pulsating after around ten minutes of him licking and sucking on my cock and balls. Yet Brad it appeared didn't want me to cum in his mouth. He'd obviously taken off his t-shirt and boxers he'd on when we'd gone to sleep, as I looked down to see his naked form. Releasing my cock and turning over onto his side facing away from me, he said "I'd love to feel that cock up my asshole". It was an invitation, but one which left it upto me, if I wanted to go further.
There had been no times in my life up to a fortnight ago, that I wanted to fuck a guy. But then I'd never had a guy suck on my cock, and only once before had I had a male share my bed and that was when I was seven. Brad's offer bizarrely didn't at the time seem strange. It was the matter of fact way he asked me, as if it was perfectly normal to him, to have a guy slide his cock up his ass. And in that context I moved over, put my cock to his rear opening and tried to ease it in. Brad quickly told me I'd need to lube him up, so not having anything on hand (Not wanting to go into the bathrom, risking waking anyone up) I did what I'd done to some of my girlfriends in the past, I slid down the bed, moved his ass cheeks apart and began to tongue his musty smelling, but clean asshole.
Brad began to squirm all over the place and also began to moan softly as my tongue lapped at his asshole. In the dim light, I could just about make out his cock and balls from my position. And it just seemed natural for me to reach for them and to begin to stroke his balls then toss his cock gently for him. Brad hunched up giving me easier access and I went for it, tossing him off and sticking my tongue as deep as I could up his rear fuck hole. His moans increased to the point I had to break off and ask him to quiet down a little. But we were both lost in our sex and before long he was moaning just as loudly again.
Breaking off, I asked him if he was ready for my cock, my sisters boyfriends reply was "Fuck me and fuck me good". He knew there wasn't any condoms, but then so did I. Even so, I moved back up, put my arms around him and had Brad guide my cock to his warm wet hole. Thrusting in when he told me to, my cock slid in and I was soon balls deep inside his hot willing hole.
It was never going to be the best fuck I've ever had, as we couldn't really go for it. Yet I still managed to power my cock into his asshole every now and then. And Brad just took it and moaned in his own sweet way. It was so fucking horny to me. There I was in my own bed, with an extremely good looking guy, who only hours before was probably sticking his cock inside my sisters mouth and pussy. And his asshole was all mine.
Changing position, with Brad lay on his back spreading his legs up and wide, I moved back into him and rammed my cock back into his ass. He grinned up at me and then put his arms around my neck. Pulling me down, Brad kissed me and kissed me hard. Instinctively I kissed him back and we were soon devouring each others tongues as I carried on fucking him.
Building up my rhythm, I pumped my cock time after time into his asshole, and Brad began to moan through our kiss. Pulling back, he whispered loudly in my ear "I'm fucking cumming man". And then in between our bodies I felt his hot sticky cum spurt out. It spurred me on and after not too much more of pounding his asshole, I too felt my orgasm rising. Telling him, Brad told me to cum inside him and moments later, My cock let go and I was forcing my cock as far as it would go up his fuck hole.
Drained and totally at ease with myself, Brad moved us so we were face to face on our sides. He kissed me again then and the kiss lasted and lasted. Only a muffled sound of someone moving next door stopped us, and even then we held each other.
Eventually I drifted off to sleep with Brad cuddling me from behind, spooning me. In the morning we both heard them all moving about and we rose, but not before we kissed and I had Brad sucking on my cock again. I didn't cum as we heard my sister shouting to us to get up, but I was desperate to empty my balls again inside of him.
Sat having breakfast after we'd both showered, my mother asked us if we'd slept well. I told her Brad was a heavy sleeper and also talked in his sleep. The look on my moms face was one of "Yeh right". but she didn't say anything. My sister however later asked me if Brad and I had had fun. When I asked her what she meant, she just smiled her innocent smile and told Brad they were leaving. His words before they our home were "See you later man, don't forget to text me about next weeks ball game". I hadn't said anything to him about a ball game, or given him my number. Only when I went back into my room, did I see a piece of paper on the side. It reads "Text me, (A number) would love to share another ball game with you".
Brad and I have had sex three more times since, and I cannot stop thinking about him when we're apart. Twice we've sucked and fucked in my car, and once in my bed as he called by as my parents and my sis were out shopping last weekend. He even stayed after to see my sister, but would have had some of my cum still deep inside his asshole from over an hours fucking, with me cumming twice up his sweet tight hole.
Strangely my sister wasn't surprised to see him at our home, and even made a comment to me "You two are becoming close, nice to see. I just knew you would". She stressed the "I just knew you would". And grinned afterwards as if she knew we'd just had sex.
Nothing has been said, but I'm now sure my sister knows her boyfriend and I are fucking. It's not the words, but her mannerisms and her easy way of being out of the way, when Brad and I are together. I'm not sure if we'll become anything other than fuck buddy's, but then a fortnight ago I was a straight guy who hadn't once thought about gay sex.
