Slender Big Breasts Sister’s Unlimited Sex Voucher – Kurokawa Sumire

Synopsis

Sumire had such strong sexual desires that her boyfriend broke up with her. One day, while searching for something in her younger brother Katsuhiko’s room, she finds an unused shoulder massage voucher she made for him long ago. While their parents are away on a trip, Sumire masturbates freely in her room when she discovers Katsuhiko masturbating outside her door. Remembering the massage voucher, she decides to create a new “creampie voucher” as a present that will use up condoms. While their parents are away, the siblings indulge their desires together.
