Aoyama Youko

Youko is working part time at a laboratory, and usually that's a nice, quiet job. But this time, as she's doing some overtime, things aren't so quiet. The office was filled with moans that night, and they were her moans. Also, they were moans of pleasure. That's because she had one of her boyfriends come over to keep her company, and they turned that place into a dirty playhouse for their perverted pleasures.
