FJIN-170 A week of full erection milking sex with a busty, apathetic caregiver sister Usami Sui

I have a weird illness where I get severe headaches if I don’t ejaculate at least once an hour. The dedicated caregiver assigned to me is Ms. Usami, who has a bit of a tsundere personality. She’s a total pervert with an amazing body, and she toys with me every day. “There’s no squirting or anything…”
」Putting on a tough act, but actually having the most sensitive wimp body. “Ah, it’s coming in…” Blushing with embarrassment, yet becoming obsessed with intense sex that could reverse their position.
From her sullen face to her dripping orgasm face, everything is adorable and tempts me. The forbidden carnal care life begins with her!
