Years ago I was out drinking and gave a guy a ride home from a straight bar.I was invited in for another drink . Not sure how it all happened but ,I assume he thought I was gay. He handed me drink and excused himself When he returned he had on a bathrobe and just walked over and opened it . First erection I had ever seen . I couldn't resist and started sucking him ,we ended up going to his bedroom to be more comfortable . I really wanted to see him cum as this point but as got close to cuming he told me he was about to cum and not to stop . I did not expect the huge amount of cum .I swallowed the best I could and the rest went everywhere .He just kept cuming . I fell asleep and was awake later by him taking off my pants. I felt embrassed because he seemed to be twice or more larger than me . When he got my pants off he never asked just said turn over .I felt him putting lube on me and I was thinking the big head will hurt but after that the rest should go fine . They head didn't hurt and as he went in I felt panic .About that time he said your ass is perfect and went deeper ,too deep . I told him to take some out but he just kept pounding away . When he started cumming he seemed to get bigger and go even deeper . Later he told me that he didn't know I hadn't done it before . I went to the bathroom thinking he may had ripped me open but no just a lot of cum .When I came out he was standing there still half hard , the head had gone from dark to pink and was just fucking huge about 4 inches of his cock was flushed and almost white .
Even though it was painful at the time I still get hard thinking about it. Never did it again but now that I'm divorced I am wanting to again
