DASD-780 I started working at a bra manufacturer full of male employees and was made to wear women's underwear. Ruise Nanase.

A male-dominated underwear manufacturer with poor sales. Amidst an environment lacking women, a handsome male employee is forced to wear women's lingerie... and it suits him surprisingly well, causing everyone to secretly get excited. From that day on, they relentlessly make the male employee wear women's lingerie and target his exposed penis and asshole. The male employee initially resisted but gradually becomes compliant as pleasure takes over.
