ESDX-141 [For Sweat-Drenched Pantyhose Office Ladies Only!] Endurance Challenge: Resisting Pleasure Under Humiliating Restraints! Natsumi, Sales Representative at an Educational Materials Company

On a scorching midsummer day, a 23-year-old saleswoman at a textbook company is returning from a meeting about an event. At the end of her workday, she is approached on the street with an invitation to take part in a survey on beauty and health for working women. She is then guided to a hot, humid studio.

There, she is offered a body-conditioning training program based on enduring whatever happens while unable to move. The challenge is intense: if she can withstand 20 minutes while restrained, she will receive a high reward of 100,000 yen.

Inside the sauna-like room, her dress shirt soaks up sweat and clings to her skin, while heat rises from her stuffy stockings in an extreme environment. As she is gradually pushed to her limit, she struggles to hold out between embarrassment and a strange sense of excitement, but the added stimulation slowly wears down her composure.

Can she endure the full 20 minutes and claim the 100,000 yen?
