My admired senior, Sumi Kurokawa, is kind to everyone at the company, and even teaches me, a useless junior, how to do my work without a sour face. On top of that, she's beautiful with a perfect figure, so I can't help but stare at the jacket bulging with the shape of her breasts and the long legs extending from her skirt. She often praises me, calling me "cute," but it's troubling because I almost get the wrong idea that she might be interested in me. During overtime in the office when we're alone, as she's teaching me work as usual, her lips suddenly press against mine—and I became her dog.
