On the tired train ride home from work, Mizusaka Kei's pheromones, even detectable over her clothes, draw the beasts to her. In the late-night train, one by one, hands reach out to touch Kei's body. As her body is toyed with and the hands of unknown men creep towards her crotch, Kei begins to twist her body in response. She takes each approaching erection into her mouth, devouring and licking them, while being drenched in the released semen. One day, as this became a routine, she encountered a particularly perceptive molester. Feeling this to be a fateful meeting, Kei and the man went straight to her home, where they engaged in intense sex with him still in his suit.
