When I was in high school I had a friend named Mark. We experimented and played quite a bit. He taught me how to cum, we sucked each other a lot and he was eventually the first to fuck me. At this point we had been sucking about a year. We had just started cumming in each other's mouths. We both spit it out at first. Mark was very sexy. Nice butt, hot stomach, swinging nutsack, and a 5" cock with a cute upward curve. It was a sunny Saturday afternoon, and we were in my second floor bedroom. My parents were doing lawn work, leaving us free to fool around. We were on my bed, naked from the waist down playing with each other's cocks. I was really enjoying it, sucking him. He started humping my mouth, making me really horny. I suggested that he fuck my mouth. Don't think we had done that before. I propped myself against the wall and he got up on his knees over top of me. He put his dick in my mouth and put his elbows on the window sill. He began to fuck my mouth in slow sensual strokes. His pubes tickled my nose and we both got lost in the blissed out bj. I was giddy from his manly aroma, his eyes were closed tightly. We established a rythym and soon he shot a big load in my mouth. I spit in the sink. I liked the taste of his cum, but neither of us wanted to seem to enjoy it too much. Eventually I would swallow everytime. Later my parents, who had been under the window in the back yard asked what Mark had been doing. I realized he had been in full view, making fuck faces as he was dicking my mouth. Ummmmm...I said "nothing", pretty unconvincingly. They let it drop, but they knew something was going on for sure. I know they thought I was gay. They couldn't have been happier when I started dating girls year later, lol. In the long run I've been with more guys than girls. I still think of all that hot teenage sex with Mark tho. So many firsts, so much hot cum...
