[SONE-140] The purpose of my hated stepfather’s remarriage is me, a high school girl… continuously violated, made to orgasm, humiliated, and raped Mochizuki Tsubomi

Koji marries Tsubomi’s Mom, to have more easy access to the daughter.

After a brutal first-time living room rape encounter, the new Dad begins to train her to be his sex pet in this grudge young/old fantasy.

I didn’t initially like Tsubomi for S1, but this movie was pretty good actually.
