Rin Matsushita discovers the male customer is her father's friend, and tells him not to tell anyone, so she'll fuck him until he cums inside! Serving a customer who's different from usual leaves him confused, yet his body is incredibly aroused, constantly moaning with pleasure. First, they shower and he gives her oral sex, then they go back to bed and masturbate before they start fucking. He's so turned on that he actively twists his waist and thrusts hard, and after he cums, he gives her a blowjob until she cums inside!
