This is a true story....I used to go to a sports centre just to flash my naked body to all....the changing rooms were near the entrance door and there were no cameras or security and the changing rooms had an outer door that was always open....basically you could walk past the outer door to the showers and everyone would see you naked but it would all seem so innocent.....no one complained and many people saw me naked - i loved it! one day, i was in one of the inner changing rooms and standing totally naked and sort of rubbing myself when I turned around to see an older man had entered the room and was watching me. He made some kind of story up about he was just visiting the area and passing by etc etc but he was obviously eyeing up every inch of my naked body...I stood in front of him and asked what he was really there for. He said i looked really good and i had a nice body. Now, i'm a straight guy and he was at least 20 years older than me but I was enjoying this guy lusting after my young body - i was about 30 then. I said i wasnt there to do any sports i just like being seen naked. He told me i was a bad boy and asked me to bend over, facing away from him. My legs were spread a little and my balls were hanging loose.....i asked him to spank me but please be gentle sir. He pulled me over his knee and spanked both my bum cheeks soft at first but harder when i said thank you sir i deserved that. This guy was ugly and a bit smelly with b.o. and stale alcohol and cigarette odours but I loved him spanking my bum hard. I felt my cock grow hard and he noticed that and groped my balls soft then hard. again, i thanked him for that. he told me to kneel down and he opened his zip and pulled out his wrinkly little dick which never got fully hard and pulled my head towards his dick and forced it into my mouth. i sucked and licked his old cock, feeling him grow inside my mouth and tasted his stale pee and felt like i was being abused - and loving it! He was getting more turned on and I sensed he would cum soon - but id never tasted another man's spunk before and wasnt sure if i wanted to but he gave me no choice...he groaned deeply and came in my mouth, holding my head as he unloaded his cream in me. I didnt like the taste at all but I loved that he was using me. He said dont swallow it you little cunt and i kept it in my mouth and showed him his spunk on my tongue till he told me to drink it down - which i did. it tasted really disgusting but I loved obeying him. after a few minutes he recovered and told me to do some exercises and perform for him, basically. I bent over a lot and showed him my naked body bending and contorting in all positions for him and i saw his trousers bulging again and i guessed i would be doing more than sucking him next time. he made me bend over and press my hands against the wall with my legs spread wide and asked me how i liked the taste of his spunk? I said i loved it sir but i was lying. I felt something press against the opening of my bumhole and was worried he was going to fuck my arse. I had never done this before and never wanted to. he told me to relax and open up for him. I did as i was told and he entered me. I as totally naked with a fully clothed guy 20 years older than me fucking my bumhole bareback and i worried he might give me a disease yet i wanted him to use me fully. I'd already eaten his sperm and so wanted him to fill my anus with that same cream. He was talking really dirty and calling me all sorts of nasty things and obviously nearing orgasm. I hesitated and almost pulled away from him as i knew he was close to cumming. but he now held my hands behind my back and i knew I had to let him finish how he wanted and then i felt something warm inside my bum....oh no, i thought and this complete stranger was shooting spunk inside my bum and he was holding me tight so he made sure every drop was in me. He pulled out and i saw cum drip from me onto the changing room floor. I felt used. I felt abused. I didnt move but i was brick hard and asked if i could wank off. he said yes, toss that off i want to see you cum. i came really quick and he loved seeing my thick spunk shoot and he tasted a little of the end of my cock then he told me to shower...i walked past the outer door as some girls passed and i heard them say he's got a semi on and giggle. the old guy had gone by the time i left the shower but i was still dripping cum out of my bum and i could still taste his pee and spunk.....that really happened but has never happened again
