[Reducing Mosaic] HMN-875 The Room You Can't Leave Unless You Cum Inside 4 men and 1 woman are gathered together in a small space and locked in, with the promise that their debts will be wiped out. The rule is that each time they ejaculate, the amount of debt they have to repay will decrease, and they will be able to leave the room. Since there is only one woman, she is repeatedly cummed inside. This is the story of an office lady. Rei Kuroshima
