I jacked off one day while sitting in the back seat of the bus after school. I was the only one in the last row. As the bus moved, the movement and shaking of the bus made me hard. Soon after I was touching myself through my pants. Finally the cock popped up through the waist line of the pants. I had a huge load on my belly. I do not know how others around me did not see me.
i used to masturbate back in the 1970's in straight porno theaters. This was before VCRs, the internet etc. My very first sexual experience with a man occurred in one of these theaters when I was 22.
It was 1976 and I was 22 years old. I considered myself to be totally straight and had never really seriously thought about having sex with a man..
The summer before I did go to a nude beach where about half of the people there were gay men, the other half were women or male/female couples. I did get excited being on display for all of them to look at but that was as far as that went. That experience did start me thinking about what it might be like to be with another man but I had no idea of how to go about making that happen and the desire to actually pursue such activity was not strong enough to make me act on it.
Back to the straight porn theater. I was in college at the time and my GF was at a different college about 75 miles away. This put a crimp in our sex life so occasionally during the week I would go to a straight porno theater in Hollywood after my classes let out to watch some porn and eventually jack off. I was always very careful, This was a big theater that at one time had been a regular movie theater and there were never more than about 20 people in the whole place, all spread through out. the theater..
I had been there sitting down close to the front of the theater for about a half hour or so. Suddenly a man came down to my row and indicated that he needed to get by me. I assumed that as I turned my legs to the left to let him pass that he was going to sit at least a couple of seats away from me. To my amazement he sat down in the seat right next to me. This was a very strange development, especially in a straight porn theater.
I was totally at a loss at what to do next. I thought to myself, "Does this man want to touch me?", "What if he tries something?", "Should I just get up and move to a new seat far away from this guy?" I decided to just stay where I was. He hadn't done anything weird but this also meant that I couldn't jack off.
I was already hard from watching the movie and suddenly this feeling came over me and I wanted to give my cock to him and to have him touch it and make me cum. This was a very very strong feeling. Somehow, I had gone from debating on whether to move to another seat or not to wanting this man to touch my cock and make me cum. .
I put my left hand down to my crotch and slowly and silently rubbed my cock back and forth through my jeans. I could feel how hard I was. Somehow this man knew exactly what I was doing without ever looking over at me and I felt his knee press against mine. There was no mistaking what he was doing and I pressed my knee back into his. I wanted to make it easy for him so I reached down and with both hands I quietly undid my 501 jeans all the way down pulled them wide apart. His left hand immediately came across and went straight for the pee hole of my boxer shorts. He found my very hard precum dripping cock and took it out and began to slowly stroke me, using the precum as lube. It felt amazing but it was not enough to make me cum and he knew it. He wanted to play with me for a while which I was fine with.
This went on for about 10-15 minutes. It was strange feeling a man's hand on my cock but it also felt really good. .All of a sudden he pointed to the exit with his finger while still holding my cock with the rest of his hand. He wanted me to meet him at the exit door which I figured would be where this hand job would turn into him giving me a blowjob. I was definitely not ready for that so when I shook my head "no" he pulled his hand back and I was left with my hard cock, bathed in precum, sticking out of my boxers.
I was disappointed that he had taken his hand away but I was way too hot to just let this end there so I put my left hand on my cock and started vigorously jacking myself off.. If he wasn't going to make me cum then I would do it myself. When he saw what I was doing his hand immediately came back over to my lap and I let him take back my cock from my hand. My cock was pretty well lubed up from my precum and this time he moved his hand much faster up and down my entire cock. It was obvious he was going to jack me off until I came, It took about five minutes after he took my cock back to make me cum... I couldn't help but look down to my lap occasionally for a few seconds to watch him stroke me. He gave a really great hand job and when my cock exploded with cum I looked down again to watch myself cum. He stroked me until I stopped cumming. It was a very strong orgasm and it was all I could do not to come up out of my seat while my cock was squirting out a big load of cum..
When I was done he then got up and left I put my cock back in my boxers and buttoned up my 501s.
This experience was the beginning of my fascination with sex with a man. I now knew that there was a part of me that really liked being touched by a man sexually but I also knew that I was more straight than anything else. I did not think of myself as bi for several years and only after I had given and received several blowjobs with other men. .
I have been completely naked sitting in adult/porn theaters and have jacked off and orgasmed in Albuquerque, El Paso,Texas, Las Cruces and Santa Fe, New Mexico. I have also gotten so aroused on long driving trips, I have stopped in restrooms and rest areas to jack off inside the stalls of the bathrooms. I have seen a couple having gay sex/anal in the stall next to on Interstate 25 near Raton, New Mexico. I have also stopped on the side of the highways at night and masturbated while the engine was idling
