A work of erotic urination featuring the cute, slender sister with nice breasts and overly sensitive nipples, Narumi Hirose. Insulting students while making them drink urine lessons, punishing a late-returning husband with urine, drowning a perverted old man in a massive amount of urine, and squirt sex with an open-legged sugar daddy... . In front of a woman who's good at acting cute, all old men turn into perverts and become obedient. The exhibition of mass urination by a tsundere slut is a must-see!
