My fuck buddy is a big-breasted, gentle, and obedient girl who's a sex toy for anyone. (Aida Tsugumi, HBAD-743)

Takeshi's casual sex partner, Tsumei, is gentle and obedient. She comes immediately whenever he calls, making her a convenient, large-breasted sex toy that can be used anytime. When Takeshi is unable to repay his debts to his friends, he sends Tsumei to sleep with him to settle the debts. And when he breaks the motorcycle he borrowed from his senior, he also makes his senior sleep with Tsumei in exchange for forgiveness. She really is an extremely convenient woman.
