After pure-looking but filthy Yuki Mizuki finishes creampie sex with her fuck buddy, he asks for a cleanup blowjob, so she demands cleanup cunnilingus in return—and the pleasure makes her explode. She never imagined he could lick semen from her pussy so skillfully. From then on, every hookup must end with a creampie, her careful cleanup blowjob, and his tongue buried in her messy hole. If he refuses to lick her clean, she threatens never to fuck him again.
