While commuting, I continue to be molested by a female employee from a business partner repeatedly.

Koichi, who had been feeling empty as he kept going back and forth between work and his house, was molested one day by a woman while he was commuting... He gets excited by the stimulating pleasure he has never experienced before, and he can't hold back and does it again. However, the other party was Akari, a female employee at a business partner. With his weakness in mind, Koichi ends up accepting the reverse molestation on the train as he is told. Koichi gradually becomes obsessed with the perverted, extraordinary life with her smiling face and teasing her without anyone else's eye...
