My mother's new husband likes cosplay photos and takes erotic photos, and even makes me give him a blowjob. I want to refuse, but my mother tells me to hold back, so I serve him. In fact, when I was a single-parent family, my mother's brother raped me, and this was still better than that. However, that uncle comes and rapes Yua. My new father finds out about this, and the unfortunate daughter is destined to be raped.
