REAL-824 Study in a group with a beautiful best friend

A younger sister argued with her mother and ran away from home. The cause of the fight was my sister's boyfriend... I was able to stay the night with mixed emotions. The brother and sister slept on the same mattress while being worried by the defenseless appearance of the younger sister calmly changing clothes in front of her brother. My brother couldn't perceive it, and he was lonely in pain... Until recently, he couldn't control his delusions and jealousy towards his boyfriend who liked to play with his body of his sister whom he thought was a child.
