This time's work involves taking a busty college girl found on the street to the MM car and challenging her to a 'Breast Squeezing & Nipple Teasing Challenge' while holding milk in her mouth. This project, with a 1 million yen prize, is about winning the prize if she can endure without spitting out the milk, or facing the penalty game of immediate insertion by a large penis if she feels and spits it out. Watching it, it's clear that enduring the vibration attacks on the nipples and areolas without spilling the milk is nearly impossible, leading almost everyone to the penalty game. However, this ironically fuels the viewers' anticipation, and combined with the busty element, it turns into a highly erotic piece. Especially this project, which showcases the director's taste, is hoped to be serialized with various types of actresses. That said, the last girl's moaning voice was personally not to my liking; although it's a reaction out of shyness, it's better to correct it before it becomes a habit.
