TYSF-038 Hire a crazy tutor

While my parents were traveling, I decided to hire a surrogate sister through a surrogacy service. However, what comes is a paripi style girl with a rude way of talking and behaving towards everyone. Furthermore, the acting girl is a super slutty woman who loves sex, and she licked and straddled my erection without permission. It wasn't what I expected, but it was super fun!
