Regardless of whether it's low-grade or high-grade, I want to thoroughly toy with Miss Tachibana, Iori Tachibana, YST-351.

Having sex with a partner much older than herself… every time they meet, she craves each other's bodies. She forcefully inserts her skilled, middle-aged man's enormous penis into her small mouth, climaxing as he sucks her erect nipples and clitoris. After they've been sucking each other's tongues, her vagina is already soaking wet, and he plunges his penis deep inside her. She arches her back, reaching orgasm multiple times, and as usual, he ejaculates deep inside her uterus.
