Koji lives at his aunt's house to attend a university outside the prefecture. I was happy to live under the same roof as my eager aunt, but at the same time I couldn't stand much excitement. I won't touch my aunt. Borrow used underwear for a while. Koji, who can no longer suppress his worldly desires, secretly sneaks into the dressing room and takes off his aunt's underwear and masturbates in a pair of panties, but is unfortunately discovered by his aunt.
