SGKI-060B - Urination endurance challenge during a video call: Can she succeed without her boyfriend noticing?

We asked a cute high school girl we met on the street to take on a game with a prize! Complete two endurance challenges to win 1 million yen!!! We've selected and are introducing a participant who showed a good reaction. The challenge is to endure the urge to urinate!! A video call to her boyfriend while trying to hold it. Can she continue the call without him noticing, even with manual stimulation or a vibrator? "No, no, I'm going to leak!", "Wait, wait!!", "I didn't hear about this!!" Trembling lower body, suppressed upper body, and secretly twitching while covering her mouth!! If she fails the challenge, there's a penalty... We won't give away the prize easily!
