Young-faced slender girl, Emachi Kato's Riding Position Time Trial Challenge! If she can make a man cum by riding him herself within the time limit, she wins a prize! If she fails, there's a penalty game with simple rules! Emachi Kato enthusiastically took on the challenge, but it seems the man held back and she failed... Thanks to that, we get to see the penalty game where she has to 'show sincerity'! She gives a blowjob to make the penis hard, then has raw sex in various positions. After that, instead of a cleanup blowjob, it turns into an irrumatio with a cumshot in the mouth in a devilish twist. Thank you for showing us such good stuff, Emachi Kato!
