When I asked the men's escort girl [a friendly, plump, big-assed girl who speaks Kansai dialect!] for a secret option, she said, "... it's just for customers," and gave me a secret, extreme service! She has a fun personality, so she's okay with inviting me on a trip! We take a mixed bath in an open-air bath and end up kissing! Then she gets all wet and horny! When I fuck her raw, her big ass shakes and she goes wild! The two get so excited that they cum on her ass and face, and even cum inside her!
