Adults' hobbies, case 7, MIUM-1214

Kasui is the prettiest girl in our clinic. She's usually cheerful, efficient, and never flirtatious—a capable subordinate. But when we're alone, her attitude completely changes; she becomes a completely different person, acting all cute and charming. We both have sexual needs, and we release them in this convenient relationship. At first, it was just that—thoughts—but gradually we've fallen into a kind of blissful, single-life-like dating game, and lately I've even felt like I've been played. Kasui's sex drive is incredibly strong; she wore extremely indecent lingerie on our long-awaited date. Even at work, she might wear revealing lingerie underneath her white coat, making it impossible to stop imagining things.
