Quickly!! Quickly, Sakuya!

Head to a resting place in this gap while the mistress is down...!!

Be elegant, Sakuya, believe in the human capability of containing the width of a mysterious infinity within a small body (in bladder terms).

When the capacity limit of the bladder (~500ml) is reached, the human body undergoes a spinal reflex called the "micturition reflex."

Because of this, there's no way to control the loosening of the internal urethral sphincter, but --

*Varies from person to person

further downstream the existence of the external urethral sphincter gives my body a chance to suppress the urge to urinate.

The dam named reason! With this, I can endure double the maximum human full limit, up to 1 L of piss!!

But I can only endure for a while, where should I run to!?

The Mistress's ability is obviously hindering my movements!

At this rate...!

Don't give up, Sakuya-san!

This voice!?
