Craziest story that your teacher told you

My teacher told us this story when he was in college, one of his friends invited him to his birthday.He arrived, then the birthday started. He had a little bit of a drink, but enough to get him drunk. Then he suddenly wanted to take a piss, so he asked his friend where the bathroom was. His friend told him it was in the basement, but since it was crowded over there, he told my teacher to just use the bathroom in his room upstairs.So he did. When he went upstairs and opened the door to his friend's bedroom, he saw one man and three women having a foursome, with one on his head, another on his lower area, and the last one on his right hand. And get this he was drunk at that time, but the moment he saw them, he lowkey sobered up a little.Then dude really had the audacity to say, "Wanna join?" But my teacher refused and told them that he just wanted to use the bathroom.Days later, after that birthday party, he ran into one of the girls, and the girl asked him if he remembered anything particular from that night. But his lying ass just said, "No, I didn't."
