I had just left the raf so was about 20. Was walking down the street and this fat, bearded guy in his sixties approached me and asked if I’d ever done any modelling. He said he would do a shoot for me and pay £150. I agreed and went to his studio, he was snapping away , I was in a football kit as he wanted to show my legs (never knew it was for a gay mag at the time. ) He asked me to take top off so I did then pants. I was quite excited and had a bit of a hard on, and felt v embarrassed, he came over and grabbed it and said ‘nothing to be embarrassed about now get it out’ I did and he took some nude photos . I was to go back the following week to check them and get my cash I felt really guilty after the photo session. Never crossed my mind anything like that before but I had had a hard on in front of a fat, old guy! I went back the next week, I sat next to him as he showed me the pics, when they got to the ones with me with a hard on, he rubbed my cock through my jeans and I just moaned as it felt good. He told me to get on my knees and if I suck him off he will give a further £50 . I knelt before him and he pulled out this really fat cock, not huge in length but thick. I just started to lick and suck it and really liked it. He then got my cock out and wanked me off. I felt really guilty and confused after that but then every time I got that urge I would go see him where he would tie me up, blindfold me and use me as I never wanted to see him as I never found him attractive at all. Never fancied anyone guy before but love a fat cock
