I've decided to teach Ria, a new office lady with a slightly natural, big butt, how to do her job. I was thrilled and looked after by the cute junior who suddenly got a chance. One day, while Ria was working overtime alone, she got a full erection from the plump butt that sticks out from her tight tight skirt, and although she knows it's no good, she immediately inserts her back and cums inside her. She regrets saying, "I've done it," but while she is grateful to Ria for acting like nothing happened the next day, she can't hold back when she sees her big butt in front of her.
