Yumi x BBC 2 (request) (Patreon)

Yumi is a foreign exchange student staying in America, and she's staying with her host family. While his wife and kids aren't home, he offers to teach her all about "American culture" and she, being very gullible and eager to learn, goes along with it but by the time she figures out what's really going on, she's already attached to him (and his dick).
