SSNI-845 The Sadistic Sister Yua Mikami

Today my girlfriend's parents went on a trip so I had the opportunity to go to her house for the first time. I didn't know she had an older sister so when I passed by her room I accidentally looked inside and saw a naked man crawling towards her feet, in her hand was a chain tied to his neck. At that time I couldn't imagine that I would be turned into such a person by her, a toy, a pet.
