Woman raped by a devilish father who enjoys her reaction to the slow insertion of a raw penis into his body until he ejaculates inside her.

The story of Suzune Anuma, Reino Kuruki, and Rino Yuki being attacked is a despicable development where all efforts are in vain, even when wearing infection-prevention masks. Their freedom is taken away, and their persistent attacks on the reluctant girls are quite compelling. The slow and persistent approach brings a freshness not seen in other works.
