I spent the night at my friend's house and fucked his girlfriend !

My friend invited me to his house to have a few drinks when it was very late my friend told me to stay at his house that at that time it was very dangerous to go out, I accepted his invitation and stayed! The next day I woke up very early and my friend's girlfriend was cleaning and she told me that the boyfriend had not given her anything at night and she wanted sex, taking advantage of that she told me that I took away the desire and she began to provoke me until I accepted and she started sucking it and then I fucked her in her living room taking advantage of the fact that the boyfriend was in his room and he still did not get up
