Due to my father's remarriage, my mother-in-law and sister-in-law will live in a small house for a while, and I and my sister-in-law will share a room for a while. However, my sister-in-law is a super gal, and every day she locks me out of the room. My sister-in-law's friend gals who came to visit are kind to me, but they use the whole room and sleep on their own, so I don't have a place to sleep! It's the limit of sloppy endurance! I'll Make My Sister-In-Law A Cock Slave At Night! The moment I approached my sister-in-law who was sleeping, I was found by my sister-in-law's friend gals who were pretending to be asleep! Life is over... I thought, "I'll keep my sister-in-law silent, so lend me your cock." And my sister-in-law also woke up and this time it's really a big pinch! On the contrary, it straddles my cock that I hated so much when I was put on a friend gal. Where's that pissed-off sister-in-law?
