Me 21F and a classmate (23M) I have at college were doing some work. He offered me to come to his place to continue the work. He was really hot, tall and muscular so I said yes hoping he didn't really wanted to continue our work. My suspicion were right because after a beer and one youtube video that was on his TV that I wasn't really watching, we started kissing and going at it. The sex was really good, I was really in the mood until suddenly he asked me to talk dirty to him. I have never done that and I had no clue what to say. I manage to say ''Go on, go on'' but I quickly realized that it was really bad dirty talk. I could see he was a bit disappointed. In a moment of stress, I said the first random thing I could think of. ''Fuck me hard baby, fuck my ass''. I have no clue why I said that and I didn't even realized I said that until he smiled and turned me on my belly and spread my ass. I didn't know what to do, I was to ashamed to say anything so I just let it happen. Just know that he his very tall and I am only 5 foot 6 and that I have never ever even put a finger in my butt. It was a very painful experience but at least it didn't last long since he came very quickly after....
