One day, Mizuki Yuki, who possesses both innocence and lewdness, had a cum-in-her-mouth sex session with her sex friend and was asked to give a cleaning blowjob, so I asked her to give me a cleaning cunnilingus in return! It felt amazing! I never knew my sex friend was so good at cleaning cunnilingus! I unexpectedly came so hard from the cleaning cunnilingus! Maybe I should make her my personal cunnilingus girl! Since then, whenever I have sex with my sex friend, it's always with the understanding that she'll give me a cleaning cunnilingus, and I always finish with a cum-in-her-mouth cleaning blowjob! Today, as usual, I quickly cum inside her and she completed a very thorough cleaning blowjob! Now, now, now, I did a thorough cleaning blowjob, so now! You clean my cunnilingus! If you don't clean my cunnilingus, I won't have sex with you anymore!
