Mio regularly enjoys casual sex with her fuck buddy, but she has always wondered why cleanup blowjobs exist while cleanup cunnilingus does not. One day, when he asks her to suck him clean after sex as usual, she requests that he return the favor. Though he rarely goes down on her, his tongue proves surprisingly skillful and gives her intense pleasure. Soon Mio wants cunnilingus everywhere—the entrance, kitchen, and bathroom. When her partner asks to have regular sex again, she agrees to a creampie for the first time in ages. After rediscovering how good fucking feels, she still finishes by demanding another thorough tongue cleanup.
