Years had passed since my older brother last came home, but he was still as carefree and handsome as ever. This time, he brought along the lovely Sally, my cute sister-in-law, and they decided to stay at our house. She seemed to get along well with my brother and fulfilled her role as a respectful sister-in-law perfectly. However, my brother remained the same irresponsible person, often leaving the house unattended. One night, after he went out drinking and never returned, my sister-in-law looked lonely and vulnerable. Drawn to her expression, I couldn't resist and ended up having creampie sex with her. From that moment on, she began aggressively seducing me time and again, deepening our forbidden relationship.
