SGKI-060C - Video call while holding urine: Can she succeed without her boyfriend finding out?

We asked a cute high school girl we met on the street to take on a game with a prize! 1 million yen prize if you complete two endurance games!!! Introducing a student who had a good reaction among the participants. The challenge is to hold urine!! A video call to her boyfriend while holding urine. Can she have a call without her 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, writhing upper body, and secretly twitching with her mouth covered!! If you fail the challenge, there's a penalty... We won't give away the prize easily!
