J'ai eu du mal avec l'amie de ma sœur

Your sister's best friend rested over at her house. Her brother, who is perverted and spends all his time looking at his sister's friend wearing her tight-fitting shorts, showing the entire shape of her body with small breasts! She knows well that he keeps looking at her. In the morning, her sister's friend went to the bathroom to clean herself. The careless brother, on the other hand, went to jerk off in the same bathroom where his friend was. And there she was astonished at what she saw!
