[Reducing Mosaic]DASS-009 My slender, big-breasted girlfriend was being raped and impregnated by my dad. Kurosawa Sumire

Sumire is dating Yosuke with the understanding that they will eventually marry. When she goes to his house to meet his father, she finds that he is her former sugar daddy client. Sumire's mood sours when his father proposes that the three of them live together, and she fears that her past might be exposed, so she reluctantly agrees. One day, Yosuke suddenly has work to do, leaving Sumire alone with his father, who then spikes her drink with an aphrodisiac and pushes her down.
