It happened a few years ago now, before I got married.
I was in Manchester late one night with no accomadation, and I called in at a all night diner. This bloke started to make conversation and I told him I had no where to go that night, he suggested his house, his wife was away. Anyway I followed his taxi as I had a motorbike, we had a cup of tea, then said it was time for bed as he was tired. I said the sofa would do me, I have a bed upstairs as the wife is away, so innocently I followed him. When we undressed he said everything off, underwear aswell. I should have clicked on at this point. I lay there thinking, what's going on, and he nuzzled up pretending to be half asleep, then he reached around me and kept squeezing my bell end, after a short while I couldn't help but get a hard on. All of a sudden, this guy, Steve, was his name moved the bedclothes away and lay with his head towards my feet, and next thing he started to gobble me off, I was lay there in embarrasment with his curcumsised cock inches away from my face. A strong feelingof curiosity came over me and I had to return the favour by taking his knob into the back of my mouth. I enjoyed the sensation of doing this to another man. After awhile I started getting a strong feeling I was about to spunk, and begged him to stop as I wanted to finish him off first, he ignored me and carried on, I rolled onto my back as I started to orgasm, spurt after spurt, it felt as if he sucked the life out of me, it was terrific. When I could stand no more, he knelt up and started to wank in front of my face, when he started to cum, he pushed his knob into my mouth, but I was so knackered I wasn't giving it my all, and didn't swallow, I spat it out. I rolled over and slept for a while, next thing he was touching my arse, he wanted to have me that was aswell, I did let him, but didn't enjoy it as it hurt, and urged him to finish quickly.
Next morning I was leaving, he asked if we could do it again that night, only with his mate there, I agreed but had no intentions of going.
But even now I still think about this experience, and imagine if it could happen again, I do fantasise still, and if the opportunity ever arrises, I will do it only next time I will take a more active roll. My wife doesn't know of this, the nearest to it has been when I have let her have sex with a few guys she met in nightclubs, and she comes home dripping with semen.We both enjoy it.
