The sister-in-law who married into my family is pure, kind, and beautiful. At night, I hear the lewd moans of my sister-in-law coming from her room, and this gap drives me to my limit. However, I saw something. After having sex with my brother, my sister-in-law was unsatisfied and pleasured herself alone… Seeing her like that made me hard. When she saw this, my sister-in-law came to me… Since then, after having sex with my brother, she always comes to me for multiple rounds of unprotected sex.
