SGKI-060 - Urination endurance challenge during a video call: Can it be completed without the boyfriend noticing?

We asked a cute high school girl we met on the street to take on a game with a prize! If you complete two endurance games, you'll win a prize of 1 million yen!!! We've selected and are introducing 3 participants who showed good reactions. The challenge is to hold your urine!! A video call to the boyfriend while holding your urine. Can the call continue without the boyfriend noticing even if stimulated by hand or using 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 the mouth!! If you fail the challenge, there's a penalty... We won't give away the prize easily!
