NACT-109 "I couldn't refuse..." How a kind-hearted private photoshoot model was taken advantage of by a scumbag client - Yui Asakaze

Yui, an up-and-coming model who charms everyone with her smile at private photo shoots, is offered an aphrodisiac disguised as a fatigue-relieving medicine by a suspicious regular customer. Unable to refuse because he is a regular customer, she drinks it, and from that moment on, her descent into a hell of pleasure begins. Her costumes become increasingly extreme, and she is driven to orgasm again and again through massages, vibrators, and tentacle torture. Eventually, she transforms into a lustful woman who craves it herself, and the innocent model descends into a sex toy.
