A curious student, hidden behind her oversized glasses, boards a packed train, her day turning unexpectedly steamy. As the train jostles, she feels a stranger's hands roaming her curves, hidden beneath her unbuttoned school uniform. Her heart races, but she doesn't stop the anonymous touches, instead, she plays along, her body betraying her with each stop. The game escalates, her uniform riding up, revealing more of her smooth skin, her breath hitching with each daring touch.
