First time sex with a man.

This story starts about 15 years ago I used to go to the gym a lot but for some reason I didn't go for a while and when I went again I didn't warm up and pulled a muscle my friend told me to go get a massage as it was part of the membership I knocked on the door and entered then I see him he was about 6ft looked like he worked out as he was well toned wearing a t shirt that was very tight on him and a pair of shorts. He told me to lie on the table and I told him what was wrong he then started to massage my leg it felt really good his hands were soft and he kept going higher up my leg until his hand was inside my shorts I know I should of stopped him but I was enjoying feeling his hands on me like that and I started to get hard he noticed and looked at me and smiled I said sorry its never happened before he said its ok only natural he then pulled my shorts off and his hands were rubbing my cock it felt so good so I let him carry on then he bent down and kissed my cock then he sucked me in gently sucking and wanking me I wanted to cum and told him so but he just carried on sucking me I came so much into his mouth he just sucked more when I had finished he came up to me and kissed me pushing my cum into my mouth I was so turned on I just wanted to repay him I took his hard cock out of his shorts and just started to suck my first cock it seemed so natural to be doing it he told me not to make him cum as he wanted to fuck me I wasn't sure about this but he told me he would be gentle so he got some oil and covered his cock with it bent me over and gently pushed it inside me it hurt a bit but in a nice way he started to gently fuck me I was enjoying it so told him harder then I was begging him to fuck me hard he said he was cumming I told him to cum inside me as I was so horny he let out grunt and shot his load deep in me. We used to meet up twice a week after that and I would go home with his cum trickling out of me every time.
