"What if we kiss?" "Can I win if I give a blowjob?" "Or should I go completely naked?" "No way!? We even have sex!?" Two beautiful friends on the street challenge each other to a sexy chicken race with a cash prize! The one who plays sexier and more extreme than their friend wins and gets the prize! How far will their friend in the next room take their challenge? Just how far will they actually go? While being mindful of each other, they each get a little information on how far their friend is going, and aim to be even more erotic themselves! The first pair is Mai (29 years old) and Yuki (28 years old), coworkers from work who are best friends and have lunch together every day! A trip to Okinawa with the prize money? A luxury shower head?! Mai is proactive, but she's so embarrassed by the extreme challenge that her ears turn red, which is cute! She can't help but cum over and over again due to the power of the vibrator! Here's your chance to monitor! On the screen, Yuki is lewdly giving a blowjob! She then gets completely naked and tries out some humping! Mai is impatient! The challenge becomes even more extreme!!! Who will the goddess of victory smile upon? The second pair is Sakura (26) and Chiaki (25). Sakura works at a restaurant, while Chiaki works as an office worker in the real estate industry. These friendly friends often drink and hang out, but are they planning to spend the prize money on a lavish lifestyle? Chiaki, who has lovely, smooth, fair skin, is shy but serious as she takes on the ejaculation challenge! She squirts during the vibrator challenge, resulting in an erotic mishap that results in a reduction in her prize money! Sakura is seen giving a blowjob during the monitor chance! And it looks like they might even have sex! This battle, which they absolutely cannot afford to lose, escalates into a creampie battle! The third pair is Kurumi (25) and Miki (25), both of whom work in the medical field. They've been friends since their school days and know each other inside and out! The prize is a trip abroad! Or moving funds! The confident Kurumi is in a state of ecstasy! It's obvious that she loves feeling good, so she takes on more and more extreme challenges! "This feels good!!!" She gets a phone call while trying to use a vibrator, and is immediately found out! Her panties are soaked! It seems that her neighbor, Miki, is also trying to use a vibrator! And now, in a monitor opportunity, she sees Kurumi about to insert herself! The climax battle continues to escalate! Who feels better? Wait a moment! Has the content of the game changed? A raw insertion to raise the prize money? Or will she be forced to cum inside...?
