Rei Aino, a slender married woman with big tits, works as an esthetician and becomes the target of a pickup attempt when she visits a massage parlor. Frustrated over her stagnant salary, she's approached with an offer for extra services behind closed doors. Posing as a lesson, she begins massaging his nipples, but soon her own body grows wet with arousal. Due to her dryness, she climaxes multiple times from just the foreplay, instinctively grinding her hips to chase more pleasure. Unable to resist her responsiveness, Rei takes him deep and receives creampie after creampie. Responding to each other's desires, their intimate connection intensifies rapidly.
