Today, my girlfriend's parents are traveling, so I have the opportunity to go to my girlfriend's house for the first time. I didn't know she had a sister, so when I passed by her room, I accidentally looked inside and saw... A naked man was crawling to her feet, and 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 of hers!!
