Taihou Daigaku Byouin no Kyouki - Dai Roku Ya

Once More into Hiroko's Enema Hell

Amid a complex relationship of hospital funds and embezzlement, Yamaguchi's wife and lover have both ended up in a dubious experimental study. The contracts have been signed, there is no backing out. Yamaguchi must choose one person to "free" from sexual persecution.

The content of the study is forced public excretion.

"It's time to choose. Will you excuse your wife or your lover from the experiment? Whichever you choose, one of them will have to suffer the consequences."

Who do you want to make scat herself in humiliation?
