A shared apartment rented by four low-paid salarymen has become a popular secret spot for compensated dating, especially since some of the tenants are married. Despite the cramped space, it has a hidden base-like atmosphere, attracting those who value privacy. One man, married for 15 years, has long been ignored by his wife sexually—his intimate life has all but disappeared. Finally, he’s arrived here. Deep in marital stagnation, this is exactly when he’s most vulnerable and ready to be seduced. From the moment they met, he couldn’t stop thinking about her breasts, and when he finally touched them, he was stunned by their incredible softness and size. Her allure is unstoppable—so overwhelming that even three men can barely handle it. How can he possibly survive this situation?
