I am a36 year old married man with 2 children and have always considered myself completely straight,that is until two weeks ago I had to go on a works related seminar with another guy from my company.Bill the other guy was in his mid fifties and I didn't know him that well,anyway on the first evening we were relaxing in the hotel bar and he was telling me about his life and asking me about mine,I was telling him about my wife and kids and showing a couple of photos of them,he commented how pretty Ann my wife was and said I was a lucky guy as his marriage had broken down some years ago. As the drinks began to take effect Bill became more talkative and told me how he had caught his wife in bed with another man,but instead of confronting them he had watched her through the open door and actually saw the man fuck her,then crept away and pretended he knew nothing of her affair and somehow got a strange kick knowing his wife was cheating on him,as he related this to me,I couldn't help but notice he was getting an erection and obviously still enjoyed talking about his cheating wife.Finally about 11.o pm I said I was going up to bed,we were sharing a room with twin beds,I used the bathroom first,Showered put a dressing gown on and got ready for bed,as Bill showered I climbed into bed and started to read a book but looked up as Bill emerged from the bathroom but unlike me he was naked and his cock was semi erect and completely shaven the bulbous head almost purple and instead of getting into bed he lay on the top with his hands clasped behind his head,I put my book down and found myself getting aroused just looking at his cock and he seemed to know just what effect he was having on me and suddenly he spoke,saying did I mind him talking about his wife and had my wife ever cheated,as he spoke my cock was so stiff and I thought about my Ann getting fucked and lied to him that she had once.When he heard this he looked over at me and said excitedly,and asked what I had done,as I made up a story about her getting drunk at a party and ending up in bed with a stranger,his cock also grew to full erection and his hand slowly rubbed it,then without saying a word he rose from his bed his cock sticking out in front of him,pulled my covers back and saw how aroused I was as I moved to make room for him. The next half hour was like a dream as Bill kissed my neck and fondled my cock and I instinctively reached down and for the first time in my life felt another man's cock we kissed and cuddled like two schoolgirls,then I felt his head move downwards and his hot breath as his lips enfolded my cock he then positioned his cock next to my mouth and gently nudged forward so his glistening head entered my mouth,I tasted his pre-come on my tongue and knew he was as close to coming as I was,then as I felt myself almost exploding with excitement Bill's finger slipped into my ass and I reached a new peak of ecstasy and spunk erupted into his mouth at the same time he filled my mouth with his hot sperm some going down my throat and some oozing from my lips.As the waves of lust subsided there was an uncomfortable silence and the realization of what I had done hit me.Bill was the the first to speak assuring me that this was all his fault and nothing would ever be mentioned again,to which I felt a certain relief but as he got into his own bed I knew I had awoken a new chapter in my life.
