A mean hottie has tied me up so well it feels good!! Akane was recommended as a parts model for a special feature on bondage, so despite her fear about this porn-like job when she's never had a boyfriend before she goes to the studio for the first meeting. It's the tall and model-like bondage master, Hayato Tsunakawa, who opens the door for her. But then, seeing how tense she is, he tells her that it's important in the art of bondage for the subject to entrust themselves to the other and... "He just started touching me... but why... does my body burn up like this!!?"
