Sayo-chan and 3P!!
While being watched by Onii-san, I had a pee-holding challenge with Sayo-chan~\(//∇//)\
Sayo-chan and I took turns designating poses for endurance, and
the rule was that whoever held it longer won!
So we endured in various poses, including the M-shaped spread-leg stance, raising one leg, standing straight, and doing the Yankee squat.

Sayo-chan was too strong at holding it, and I couldn’t win at all…
While Sayo-chan held it with a cool expression, I was peeing profusely,
it was miserable… lol
But I had never seen a girl wet herself up close like this, so I was excited! Sayo-chan’s wetting was incredibly cute ♡
And finally, we measured the amount we peed over two hours

Since I had slightly more volume,
Onii-san gave me a reward.
But it was really close!
Sayo-chan, Onii-san, thank you very much!
3P was so much fun, I want to do it again soon ♡
Thank you very much.
↓The drinks Sayo-chan and I drank beforehand lol
