[Wanpaku Shoujo (2=8)] Boku ga Chichi no Kataki to Sex Suru Riyuu [desudesu]

A short-haired tomboy in a judo gi and bike shorts offers herself to her father's hulking rival, begging him to finish inside her without protection so she can get pregnant and leave home as soon as possible. As he pounds her plump, sweaty body into the mattress she keeps seeing her dad in the older man's relentless strength, torn between guilt and the way it makes her moan for more. The story closes with her knocked up and nursing their baby mid-round, teasing him that she wants a second child and that the boy had better grow up strong enough to defeat his own father.
