Oosawa Mika, who enjoys masturbating while fantasizing about being taken by strange men, is taken to a park without panties. Lured into a situation where she will be trained by men recruited from a BDSM forum, she experiences far more excitement than she ever imagined. Drawn deeply into the scenario, Mika's pussy becomes soaked just from anticipation. Her mouth is violated by the cocks of the gathered men, engulfing her in unprecedented pleasure and arousal. Each time her pussy is finally penetrated by a stranger's cock, she cums repeatedly, over and over. This intense, feverish experience only serves to heighten her deepest desires even further.
