Reducing Mosaic HMN-875 The Room You Can't Leave Unless You Cum Inside: Four men and one woman are gathered together in a small space, promised 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 can leave the room. As there is only one woman, she is repeatedly cummed inside. This is the story of an office lady. Rei Kuroshima
