Ai-chan, a beautiful girl with a very short haircut, came to stay with me without telling her boyfriend. She came wearing see-through panties under her pantyhose and was full of energy, so I did my best to live up to her expectations. The flesh of her buttocks peeking out from under her see-through panties was so soft and sexy that I couldn't resist sticking my head into her buttocks and enjoying her private parts and anus. We had sex as much as we could during our overnight trip, not caring if her pantyhose got torn. She was transformed into a beautiful girl suited to being a mistress.
