Keep trying to move her!

With a huge burst of energy, I pulled my hips away from the vice of her clenching legs, and scurried up to the far end of the bed, trying to escape the growing puddle. Anna gave a little grunt in her sleep, her hips continuing their rhythmic grinding against the sodden sheets. It seemed her flow was finally easing up.

With a soft groan, she rolled onto her back, legs falling open as she did. Her thighs were glistening with moisture, and where they joined, a thin strip of fabric was drawn tight across her cunt. It was almost transparent due to the soaking it had endured. Yellow liquid gushed around it, slowing to a trickle that flowed down the curve of her ample arse. A few final spurts of piss shot out, missing the edge of the bed completely and landing on the carpet. Her hips bucked with each spurt.

At last she lay still, head lolling to one side.

"Fuck fuck fuck fuck" I muttered, jumping off the bed and out of the puddle of piss that had spread over it.
