It was one of many innocent conversations between a father and a son, he asked me and i told him some of my experiences. but so much talking about sex made me horny, he realized instantly. i went to kiss him, but not on his cheeks like any son would, i did it on the lips. i know that he was not expecting it and that he also got hot, in fact he showed it to me later. i threw myself on him and we began to undress, his male body had always made me very horny, he was strong and was well marked despite being a mature man, it didn't take long before he took his cock out of his pants to place it in my mouth, he wanted to feel it and suck it. then he tasted my cock too, and soon after he was penetrating me. he first started off soft, but after a while you see that he got too hot and he fucked me quite hard. for moments i felt him so deep inside and with such force that it even hurt, but still i wanted it to continue until he came. and he did it on me of course.
