I had a sexual relationship with another guy that started when we were in 7th grade. He initiated the contact but I never resisted until I started getting girls to do the same stuff. He and I were still close friends and he tried off and on to get me to do the stuff we had been doing. We use to just jerk each other off when we did stuff, nothing more except rubbing them together. At 18 we hadn't touched each other in almost 4 years and one night we ended up alone. He tried and I let him play with my dick and jerk me and I felt bad for him so I started feeling him up. He quickly took his pants off, we were in a car and it was dark but when I felt his dick it had gotten so much bigger. I could see it in the moonlight and I was mezmerized by it as I stroked it. I suddenly had the urge to suck him and I had never had that urge before. We had been drinking beer but weren't drunk. I just couldn't take it anymore and I was fairly close to it so I leaned in and started sucking on him some. He became very excited and went down on me as well. We were finally able to position where we could suck each other at the same time. We ended up doing this for around five years.
One night we got caught by a girl that had been trying to fuck him. He didn't go for girls at all. After she left we started up and in just a few minutes she came in on us. There was about 10 seconds of extreme fear for both of us until she started stripping of and joining us. I've been in lots of three ways but that was the first one where it was two guys and I was sucking the guy with the girl. She never told anyone as far as we know, she kept coming back for more for the next couple of months. I was very afraid she would tell but what could I do but keep doing it, I was afraid of making her mad.
