One day, Rima, a J-type girl, is a victim of molestation on the train while commuting to school. Humiliation... Rima, who can't even ask for help... ends up cumming from the persistent caresses of a middle-aged man. Every day, every day, on the same train, her nipples are touched... she's made to cum... and eventually even her dick is inserted and she's creampied... It should be absolutely, absolutely unpleasant... but it feels good... Tomorrow too, I'll end up wanting the old man's groping at the same time...
