Let me begin by telling you a little bit about myself. I would define my sexual orientation as "bisexual" (sort of). I love sex with women. When it comes to men, I am only really sexually attracted to them for the thought of being submissive to a dominant guy. I have no desire to put my dick in another guys ass, but I LOVE sucking cock and getting fucked in my ass. Anyway, the following story is 100% true, and it was one of my very earliest sexual experiences.
When I was about 18 years old, I lived on an Army base with my mother and my stepfather. I have no brothers or sisters, so it was just the three of us. We lived in a some sort of apartments that were for enlisted men. It was a 2 story apartment with 2 bedrooms, both of which were on the second floor. When we moved to this places, we moved away from my girlfriend back home. I barely knew anyone, and I really missed sex with my girlfriend. Being 18, I was constantly horny, and I now had to rely on masturbation to find some relief.
Anyway, one day my stepfather announced that we would be having a guest come stay with us for a while. His name was Kevin. He was a young man about 23 or 24 years old, and he was a newly enlisted guy in my stepfathers platoon. Kevin seemed like a nice enough guy, and because he was somewhat close to my age (compared to my mother and stepfather anyway), he and I would hang out sometimes, throwing the football around or whatever.
Because there were only two bedrooms, it was decided that Kevin would share a room with me. We had separate beds (actually, Kevin just slept on a mattress on the floor), and we would lay awake at night and talk about random things. My parents always turned their TV and/or radio on when they went to bed, and kept them on all night. My stepfather always said it was because he had to have some kind of background noise to sleep, but I assumed that it was also to give him and my mom some privacy and keep me from hearing what they were doing in their room.
One night, Kevin and I were talking, and he kept complaining about how much his back was hurting. He asked me if I would mind giving him a back massage. He said it would really help him sleep. I hesitated at first; it seemed like a lot of effort on my part, plus I wasn't really excited about the thought of rubbing another guy's body. Kevin said he actually had some experience giving massages professionally, and made a fine sales pitch to convince me that it wouldn't be "gay" to just give a back massage. He assured me that if I gave him a massage, then he would do the same for me. When I was a kid, I used to LOVE having my back rubbed, it was so relaxing, so I decided to accepted his offer.
He and I were both wearing nothing but our underwear. I got down on the mattress with him on the floor, and he laid on his stomach. I proceeded to give him a back massage the best I could. It was actually more like a back rub, but he seemed to be pleased with it. He then rolled over onto his back, and asked me to rub his chest as well. I did as he asked, and I couldn't help but notice the bulge in the front of his underwear. His cock was obviously hard. I found the sight of his stiff cock surprisingly attractive. I couldn't explain it; I can't look at another guy's hairy body and think it is sexy, but that stiff bulge in his underwear sure stirred something primal inside me. I felt my cock begin to stiffen just a little as I stared at his bulge.
