Descriptions:
Me and my girlfriend are university students. Her sister “Nanami” is a schoolgirl. This Nanami is actually a masochistic woman with a quiet look on her face… One day, Nanami noticed that I was watching her and seduced me by showing me her masturbation. I was surprised, but decided to train her sister to be such a pervert. Repeated masochistic training without her eyes… My relationship with her sister escalated day by day, and I became a complete masochistic bitch who repeatedly climaxed in bondage sex.
