See how much more piss she's holding

Anna had already unleashed a huge torrent before, soaking both of us, and she still had enough in her to leak on the shower floor. Despite myself, I was curious; just how much was this girl holding in?!

I stepped into the cramped shower stall and placed one foot just above the mound of her pussy. She didn't stir. I gently pressed down with my toes, feeling the pressure pushing back at me. A little spurt splashed out across the tiles.

Intrigued, I shifted my foot down, so the heel was against the sopping wet gusset of her panties, and pushed with my toes, harder this time. Anna gave a guttural moan, deeper than any of the others I'd heard tonight, and a hot spray gushed over my foot. The sensation of hot piss trickling between my toes was strangely erotic, and I leaned onto her strained bladder again.

I was rewarded with a slightly smaller trickle this time. I suppose that was the rest of what she'd been holding. Still, it was an impressive amount. I let my toes wander down, trailing along the soaked gusset of her panties, toying with it. I slipped my big toe under the band of fabric, feeling the slick folds of her cunt open around it.
