"Are you friends?" He noticed her skirt was rolled up and he was secretly peeping, hiding in his bag! But the girl next to him discovered him, and he ended up being used against his vulnerable spot multiple times. (DANDY-967)

In a crowded train, a man is caught peeping to the woman, who is hiding in her bag and groping her. Just when he thinks he'll get caught, he's instead subjected to a "keep going w" vigilante admiring his penis or masturbating. He initially thinks she's a good girl, but it turns out the peeping girl is her friend, leading to a tangled relationship between the two! The man, having his weakness exposed, is then subjected to a penis-playing session or blowjob on the train... They move to a sparsely populated area, where he is punished with a threesome.
