I suffer from a strange disease where I get a severe headache if I don't ejaculate once every hour. The person who came to be my exclusive caregiver is Ms. Usami, who has a bit of a tsundere personality. I'm completely at the mercy of her every day, as she's a natural erotic lover with an outstandingly voluptuous body. She puts on a tough front, saying, "I'm not squirting at all...", but in reality, she has a sensitive "zako-man" (weak pussy) constitution more than anyone else. While shyly saying, "Ah, the cock is coming in...", she becomes obsessed with the intense sex that feels like a reversal of roles. From her grumpy face to her melting ahegao, everything about her is adorable. With her seducing me, a forbidden life of carnal care begins!
