Natsume Rinka, whose cute face contrasts irresistibly with her grotesque pussy, is taking on the challenge of the standing doggy style championship! After filming, Rinka is in a completely relaxed mood, so we propose the standing doggy style championship to her, but she doesn't seem to be very enthusiastic, perhaps because she lacks confidence in her physical strength. We manage to convince Rinka to take the challenge! Once we've decided to do it, she takes off her clothes like a real man, and stimulates the penis and makes it erect, which is a given for a professional. This standing doggy style championship is a little different from acting-filled sex, and it's a matter of the actress' pride! Watch the video to see if you can make her cum within the time limit!
