On my long-awaited family trip, my stepfather changed her eyes and started inserting her in... I can't tell my mother about the events that happened during this trip, even if her mouth slit.

Shion's mother remarried to Ginji, a company president and a small wealthy man. To celebrate Shion's acceptance for university, he comes to a family trip to a hot spring resort. My stepfather peers into Shion in the bathroom and sexually harasses him drunk at the party. Finally, Shion is attacked by his stepfather, stealing his mother's eyes... "As a father, I have to teach him how to suck a cock," he repeatedly fucks his stepfather over and over again. If I hold back on sex, I can stay happy with my mother... S1's forbidden immoral drama, a new series of incest!
