I enjoy wearing tight running nylon leggings, and this day I thought that I would like to wear a pair of my wifes worn G- strings under them and go out for a walk. Hell they did feel so nice as they hugged me so tight and showed my bum and bulge off for all to see.After about 2 miles I came upon a small bridge over a running stream so I lent over so as to see the water going under the bridge, as I was stood there a man came alongside me and said hi mate they are a lovely pair of shiney legging you have on there. I thanked him and replied that they felt nice as well, with that his hand was running up and down my bum.Mmmm they do feel nice do you mind if I walk with you for a while? No I don't mind at all, so off we went talking about our likes and dislikes. It turned out that he was dom And I am sub, after 10 mins or so he said follow me, down this overgrown path we went which ended at a iron gate, this will do he says, do for what I said? He turned to face me and I could see that he had his cock in his hand, you are going to suck on this you little sissy. So I knelt down in front of him saying be gentle it's my first time. Just lick my balls and shaft for a while, this went on and all of a sudden his hand went around the back of my head and he slide his hard cock into my wet warm mouth, now holding my head with both hands he pulled and pushed my head as my lips slid gently over his hard shaft in and out mmmmm he said I knew you were going to be a good little cock sucker. All of a sudden I felt his cock pulsating as he came in my mouth. Afterwards he said it's a pity im on holiday as I would like you again, I must admit I did enjoy it as well but did not let on to him.
