A baby-faced, slender girl, Kato Ema, takes on a time trial cowgirl challenge! If she can make the man cum within the time limit while riding him, she wins a prize! If she doesn't, she has to play a penalty game - that's the simple rule! Ema was all excited to try it, but the man held back and she failed. Thanks to her, you can see the penalty game, "Show your sincerity!" She makes the man's dick hard with a blowjob, and then has raw sex and cums in him in various positions. After that, you think she'll give him a clean-up blowjob, but then she starts deep-throating him, and he cums in her mouth, which is a crazy development. Thank you for showing us something good, Ema!
