Mai, a literature student at a well-known women's university in Tokyo, is the type who constantly fantasizes about erotic scenarios while being tormented by intense stimulation, unable to control her arousal. During hotel sessions, she shows no resistance to elements like blindfolds and light BDSM—when immobilized and teased with a vibrator, she bursts into tears, sobbing "I'm sorry, please stop," soaking her panties from arousal. During penetration, she consistently experiences deep vaginal contractions, actively seeking out humiliating positions that highlight her eroticism and vulnerability.
