"Unable to refuse..." A gentle personal model is exploited and violated by a sleazy client until she is completely assaulted. (NACT-109)

Yui, a rising model who smiles brightly at her solo photoshoot, is recommended an aphrodisiac by a suspicious regular customer. Unable to refuse because he's a regular, she drinks it and begins her descent into a hell of pleasure. Her clothing gradually becomes more extreme, from massages to vibrators, with tentacles used to torture her until she's forced to orgasm multiple times a day. Ultimately, she becomes self-willed, her appearance changing lewdly, the innocent model degenerating into a sex toy.
