Shameful Wife's Lewd Humiliation Train ~ The Junior Who Falls in Confusion as M Awakens

Jojima Keiji is a repeat offender who frequently commits sexual harassment.
He has repeatedly groped women on trains right under the noses of the authorities.
He believes that no woman can resist his "techniques," and has already ensnared many women, making them his captives.
Some of those women have even been reduced to shamefully exposed sex slaves, and he has filmed them, trading the footage in secret for profit. He even considers this a calling that combines "hobby" and "profit."
Then one day,
Jojima is out looking for prey as usual.
Since he woke up later than usual, the train has already passed rush hour, but he still begins scouting for today's target.
Then, a woman catches his eye.
She is not young, but she doesn't look old either.
However, the mature allure she radiates makes Jojima sense a certain masochistic tendency in her. The target woman is standing near the train door, in an ideal position.
There are few people around, so Jojima seizes the moment, approaches her, pretends to grab the overhead strap, and as the carriage sways, he begins to touch her.
The woman's body stiffens, reacting just as he expected, so Jojima grows bolder.
On the other hand, Kamiyama Reika, the target, is at a loss over this sudden incident.
Yesterday, she mustered the courage to express her desires to her husband, but he rejected her with excuses like "I'm tired" and "Can't we stop doing this?"
Reika feels lost about her mature body, and her husband's words have deeply hurt her.
She begins to wonder if she has lost her feminine charm...
Heartbroken, Reika decides to take a bold step to test whether she truly has no appeal.
She puts on the revealing outfit she had been too ashamed to wear before and goes out, thinking that if she gets some pick-up attempts on the busy streets, she might regain her confidence.
Otherwise, she would truly believe she has no charm at all...
Still, to avoid the embarrassment of being seen by acquaintances in her local area, she deliberately takes a train to a neighboring town, but on the train, she feels nervous, thinking people are staring at her bold outfit.
It is at that moment that she encounters the habitual groper "Jojima Keiji."
