A woman who lands a job at a company specializing in men's underwear quickly notices something unusual about her workplace. Her senior colleagues in the department are all slender, stylish, and boast big tits, radiating a strikingly sexy aura. Every time a meeting starts, she can't help but stare as they change into the company's underwear, and even though she's normally level-headed, her cock heats up, reacting with a massive hard-on. Yukishiro Miho advocates for functional, design-focused underwear, while Asakaze Yui pushes sexier styles that appeal to men. Torn between their proposals, he blurts out, "What would it feel like to suddenly touch your breasts through the bra?" as he gropes her chest, then sees a gorgeous big ass appear before him, asking, "Which panty line do you prefer?"—pushing him to an uncontrollable, monstrous erection. He panics, expecting anger, but instead, both women kindly start stroking his cock. When Yukishiro removes her bra, her perfect big tits press tightly against him, sandwiching his body as they team up to pleasure him. Alternately teased and overwhelmed, he can't hold back and cums deep inside. At this company, where work and private life blend into thrilling excitement, lifelong employment seems guaranteed.
