Koji lives at his aunt's house to attend a university outside the prefecture. I was pleased to live under the same roof with my eager aunt, but at the same time I couldn't bear much excitement. I won't touch my aunt. Borrow used underwear for a while. Koji, who could no longer suppress his worldly desires, secretly sneaked into the dressing room and took off his aunt's underwear and masturbated in a pair of panties, but was unfortunately discovered by his aunt.
