Ryota ends up staying at his aunt's house for a limited time until he graduates from university. Although she was worried about living far away from his hometown, she was even more happy to be able to live with his aunt, whom he admired. However, as they live together, his sexual desires begin to grow. Before Ryota makes a mistake, he comes up with the idea of using his aunt's underwear to satisfy his desire. He indulges in playing alone while smelling the scent of female scent from freshly taken off panties and other panties, but...he runs into his aunt...
