Have you heard of manguri-gaeshi? The position where the buttocks stand up high like a mountain for the purpose of cunnilingus or deep intercourse is called “true manguri-gaeshi”, but it is rarely seen these days and has been arranged in a modern style. The women who gathered feel embarrassed about the true manguri, but they try to see if they can produce a poop that resembles an eruption. The poop that comes out with a painful squelching sound is just like the cry of nature. Some even pee and have a big accident. And for further rewards, they also take on the milk enema challenge, spraying white liquid like steam from a geyser. It’s unprecedented. The sight of them working hard and their bodies being decorated with poop and milk that defy gravity is a sight to behold. You will be able to smile and cum involuntarily as they take on the challenge with joy.
