I am 41 now and very much bi sexual.this story happened when i was about 18 and very new to having sex with other men.i had a job delivering leaflets thru doors for $10 for 1000,was hard work.It was summer and in the middle of the day so i was delivering the leaflets with my top off. I got to this house and saw an old man looking at me from a couple of houses away,i thought he was going to tell me to fuck off and not litter his letterbox.He hadnt stopped looking at me until i got to his front door,where he was standing waiting.As i put the leaflet thru his door he opened it and was standing there in a very short pair of shorts with a sizable bulge at the front.He was looking at me up and down with a smile on his face,it was quite a turn on.he said i was going to grt burnt unless i put suncream on.i asked if he had any and he said he did,so i followed him into his living room.i waited there until he came back in,the bulge had got bigger in his shortsand i couldnt take my eyes off it.he asked me to turn around so he could put cream on my back so i did.he was standing very close,so close i could feel his bulge touching my bum.he was putting cream on my shoulders with very firm hands then onto my lower back and around my sides.when he got to the small of my back i lent forward slightly,he pushed his crutch firmly at my bumso i responded by pushing my bum back at his cock.he masterfully pulled down my shorts in 1 movement and had both hands on my butt.He parted them and inserted a finger,it felt so good i wanted more.i told him to stop fucking around,get your finger out of my arse and get ur cock in there instead.he didnt take any time in getting his cock out and pushing it towards my hole.it didnt take him long to have his bell end in me and slowly feeding the rest of his cock in me.it felt like a nice size going in.he was giving me a good fucking by now and i was loving it as much as he was.i could feel his balls slapping myn as he was fucking me,i could feel he was near to cuming so i reached back and felt his balls and gave them a little sqeeze to help him cum.boy it did the trick,big orgasm and a big amount of cum he pumped into me.when he finised he pulled himself out of my arse and sat down.i pulled my shorts up and said my goodbyes and off i went on my very merry way.
