Too angry because his best friend played the music too loudly and even knocked on the door to remind him that he wouldn't open it, Katana poured all her anger into breaking the door and not forgetting to curse and insult him. But it's not easy to bully your best friend, and he's not medium. When she went to take a bath, he peeked and even discovered the scene of her masturbating in the bathtub, but unfortunately she found out, and the punishment he had to suffer was a pile of dirty bowls and chopsticks waiting ahead. However, it is only a secondary punishment, the main punishment is even more tiring and hard when you have to use all your strength to serve your sexual needs, helping your lascivious friend to orgasm in the near future.
