MDTM-105 — My Submissive Sister Who Wants To Be Tied Up, Kotone Suzumiya

My submissive little sister... "Kotone" has a very serious and pure personality... but at home she is my human toilet. Her body gets wet from the rope that digs into her... her lower body becomes sensitive. "For my brother..." she says, happily servicing the penis of a man she doesn't know... My little sister feels joy every time she is kept as a pet. "I want to be connected to my little sister more..." Her masochistic love accelerates. The whole story of my twisted sexual tendencies.
