The pervert lurking on the train has set his sights on a seemingly docile, small, and cute uniform girl!! Just a little bit of teasing, and she's already climaxing and wetting herself on the train. Taking advantage of the fact that she's scared and can't resist, the pervert's actions escalate! Despite being on the train, he inserts his raw penis from behind, parting her buttocks! The girl, who doesn't want to worry her family and can't even consult them, rides the train every day trembling with fear of the pervert, but for some reason, she also begins to look forward to that pleasure of being perverted again...
