A Room You Can't Leave Unless You Cum Inside: Four men and one woman are gathered together in a small space, locked in with the promise that their debts will be wiped out. (HMN-875)

中出ししないと出れない部屋　借金返済がチャラになると集められ狭小空間に閉じ込められた男4人、女1人。 射精する度に返済額が減額し、この部屋を出られるルールのために女ひとりしかいないから中出しされまくったOLの話。

Trapped in a small space containing only a bed are men and women who have been deemed unable to repay their debts.
As a social experiment to combat the declining birthrate, the rule is that if they impregnate the woman, their debts will be wiped out. – Jav.wine HMN-875
