Toa Yuki was targeted by a pervert on her daily train commute. She never imagined that the man's fingers creeping up on her would feel so good. It's a perfect match! Even though she knows she shouldn't want it, her body craves it. In the silence, her own love juice overflows and drips like silk! The thread that binds them together isn't fate but depraved love juice. After becoming submissive, she falls into an impure relationship and gets on the train where the man is waiting today.
