I was 18 and my best friend was 19. I had a girlfriend and we had a fun, enthusiastic sex life on weekends when I went to the city she was in. One weekday when I was bored at an office job I started getting turned on wondering what sex with another guy would be like. With that in mind I rang my friend, knowing that he was usually up for anything, and arranged to visit him that night at his college.
That evening I went over and we sat in his quite small and old fashioned college room. He rolled a joint and I suggested we smoke it nude. He then suggested we sit in his closet. So we undressed and sat in his closet with the room lights very dim – just a shaded lamp in one corner – and smoked a joint.
We were very self conscious and sort of embarrassed but excited. Our legs and sides were touching. We were discussing our sex lives with our girlfriends, what we liked to do, what we hadn't done yet but wanted to.
After a while I suggested we massage each other. My friend went along with it. Our voices were staring to sound nervous – some stutters and shakiness.
He lay down first and my heart was pounding. I stroked all over his naked back, legs and buttocks. Then he got up and his cock was semi-erect. I could see he was getting aroused. Then I lay down and he did the same to me. My cock filled with blood when he stroked the back of my thighs. But not fully erect – we both had semi hard-ons.
I rolled over and exposed my cock to him and he stroked all around it, bringing a bead of fluid to the head. But he didn’t touch it.
Then I asked to do his front and the same thing happened.
We were both too nervous to make the final move.
So we started talking about how exploring each other’s bodies would help us better understand our girlfriends and how they relate to us. Which was something to say to make us more comfortable, but also true, I guess.
Anyway, so we were both there, horny but still. The conversation petered out. Then he put his hand on my stomach. I said, “Can I go down on you?” and he said yes. He lay back and I lay on him so we could kiss for a while, tongue pashing, and then for the first time in my life I took a penis into my mouth. The hardness and urgency of his erection was exciting and I bobbed and licked and sucked until he was holding my head and thrusting into my face. I gripped his buttocks and pulled up and he groaned and cum started pulsing into my mouth. I swallowed and swallowed.
Then we swapped positions and he took me in his mouth. It felt great. He really went to town with his mouth and even played with my balls, and it wasn’t long before I had my hands clamped on his head. I arched back and exploded into his mouth. He swallowed.
So then we both lay nude together on his little bed, our cocks softening, each other’s cum settling in our stomachs.
I jerked off about five times the next day thinking about what we did. And over the couple of years we kept blowing each other every now and then, even a few times in broad daylight at his parents' home, and almost getting caught by other friends a couple of times.
We never told our girlfriends, but we did have some threesomes with them - without them knowing what us guys sometimes got up to on the side.
