It was the stories on the walls of the toilets that got me started.I'd read them and get feel ashamed,then feel even more ashamed when I'd wank at night thinking about them,it wasn't as if I was homosexual,I liked looking at girls,I also thought about what it would be like to have sex with a girl,but I couldn't stop myself thinking about naked men when I wanked. My first time I was spied on doing it was an unforgettable experience,I was in the cubicle reading the stories and looking at the drawings,it was the second time I had ever taken all my clothes off in a toilet,as far as I was concerned I was in a private place..I don't think I was going to wank myself off there and then,even though I was wanking I was saving myself for when I was in bed to pull myself off. I don't know how long he was watching me but I was suddenly aware that he was above me looking over the top of the partition,he started to say how nice I looked and as I struggled to get my underpants back on,suddenly an extremely difficult task as he's saying things to me that I didn'nt really understand. Now you would think that I would never do anything like that again,but the very opposite was true,that night in my bed I wanked myself off like never before,then felt very guilty,but the guilt only lasted until a couple of days later when I had spent what seemed ages trying not to want to wank myself,I couldn't hold out any longer,but now just wanking myself was'nt enough,I had a massive urge to experience been seen naked by a man again and to say I was nice looking. I went back to the toilet,my sexual desires overpowered my fear,I waited naked in the cubicle but nothing was happening,I unlocked the door and went out into the main toilet completely naked,I was the only person in there,I was actually disappointed.Then I did something unbelievably stupid,I nipped into the cubicle next door just to see if there was also writing on the wall,in that second or so I heard the footsteps at the door,my brain stopped,I pushed the door closed thinking,hoping he would have a pee and go. He went in the cubicle where all my clothes were,I could hear him,I had never been so frightened in all my life,I had no idea what to do.I heard him open the door and come out,he was leaving,he came to my door,which to compound matters didn't have a bolt on,he pushed it open,I wasn't expecting it,I remember the only thing he said when he saw me completely naked,fucking hell. He worked everything out in an instant,I think you had better come and get your gear he said,I had my hands covering my cock,I had no choice but to go with him,but once inside his/my cubicle getting me back in my clothes was the last thing on his mind,he wanted my naked body and I knew I was powerless to stop him if I wanted to get my clothes back,I reached for my underpants but he took them from my hand. Reaching for them was a mistake,I'd taken my hand off my cock,he did'nt miss the opportunity,he pulled me onto him,I was completely overpowered,his hands went behind me,he held me in a powerefull enbrace,his hands holding tightly onto the cheeks of my bottom,I could smell him,he was almost gulping for air,one hand came off my bottom and went in between us,even though my cock was completely limp he started to,as much as he could manage,wank me. The impossible started to happen,my cock started to harden,surely under the circumstances that could'nt happen,but I could'nt stop it,he was becoming completely sexually wound up,the weirdest thing was happening in my mind,my fear was gone,I was beginning to like what he was doing to me,I don't know if I was responding to him but I was'nt fighting him off. I don't know if I could have grabbed my clothes and run as he started to take his clothes off,I actually wanted to see him naked,compared to mine his cock looked enormous,swollen,throbbing as it moved up and down,the deep pink head fully exposed and shining from his precum.He pulled me back onto him again his big hands going behind me and holding my cheeks,but now I could feel the heat and the throbbing and the hardness of his cock,he was a lot taller than me and he was grinding onto my tummy. The only way I can describe what he was doing was ''shagging me'' and the thing was I did'nt want him to stop.It was the first time I felt a mans spunk on my skin but it was only as his cock started to slide over my tummy and I became aware of the extra wet heat that I realised he was spunking on me,I was also aware that he was making a lot of noise as his breath came in ever greater gasps. I felt him relax his grip,he was spent,he unrolled toilet paper and handed me a handfull,he squeesed the last of his spunk from his cock and cleaned himself,my tummy was covered in his spunk,first time I cleaned spunk off myself in a public place,it would'nt be the last. I don't know if he knew I had'nt spunked but I suppose he did'nt care,he'd used my body for what he needed,the funny thing was I liked it,really liked it.
