My son lost his rationality due to the smell of sweat that sniffed his mother's throbbing sweat after he returned from his part-time job.

It's a hot, humid midsummer day. "Mom, I'd catch a cold if I slept in a place like this," Yu, who works hard at a supermarket, is often sleeping on the sofa. A irritating smell tickles the nose cavity of her son Haruo, who approaches her to carry her to the bedroom, as she is concerned about her tired Yu. "What is this smell..." A fragrant smell of sweat that directly appeals to your instincts. I want to smell the deeper scent closer. Captivated by desire, Haruo searches for the source of the smell and forces her to approach her gently.
