I've always been social, and when I was growing up, always had friends spend the night. Like typical guys, we'd talk about girls, sex, our boners, jerking off, and sports. I remember late at night we'd get into our sex talks, and guys would laugh and joke about wanting to jerk off, or what they'd do if a girl was there. Occasionally I'd hear influctions in their voices, and knew they WERE in fact jerking off while we talked.
Sometimes I'd actually find crusties on my bedding or pillows. I'd laugh it off, but insist on doing my own laundry. I didn't want my Mom thinking I had done all that.
One night my friend Ryan and I stayed up til two am after four other guys fell asleep. We kept talking about our boners and briefs, and the difference between wearing them, and boxers, and how boxers don't help cover a boner. I watched his silouette as he adjusted himself several times under the sheets. I was secretly jerking off while he talked about feeling himself cumming. I could completely relate! I was laughing at his punchlines, and keeping my voice in moderate tone while I responded to questions, so as not to give myself away.
I came quickly, and held my breath for almost a minute until my boner softened and stopped shooting. He asked if I was still awake, and I quickly said yep. He asked what I was doing, and I just said thinking. I could see him moving around a bit. I confessed that I had jerked one out while we were talking. He was quiet for a minute, then said 'me too.' I sat up and laughed. I told him I had to change, which he got up with me. I grabbed underwear from a drawer and slowly shuffled downstairs where the duffle bags were stacked by the back breezeway. I turned the light on and we started laughing, as we saw each others' crotches were soaked. We still had semi boners, and made our way back up to my bathroom, where we quickly stripped. I noticed he had a lot more hair on his body than I did, and he had a few more muscles too.
We quickly changed, and left our clothes in the hamper. We fell asleep shortly after, but several times, he'd spend the night, and we'd talk late into the night, and masturbate together. Not saying anything of course, but knowing what we were doing.
