Mio-chan enjoys having sex with her sex friend every day. However, she has often wondered, "Why is there no cleaning cunnilingus, even though there is a cleaning blowjob?" One day, as usual, her sex friend asked her for a cleaning blowjob after sex, so in return she asked him to do a cleaning cunnilingus. Her sex friend doesn't usually do cunnilingus, but he is quite skilled and Mio-chan found it very pleasurable. Since then, Mio-chan has been enjoying cunnilingus every day, from the entrance to the kitchen to the bathroom, but she listened to her sex friend's request to have normal sex, and allowed him to cum inside her for the first time in a long time. After reaffirming that cunnilingus is good, but sex feels good too, Mio-chan asked for a cleaning cunnilingus after all!!
