Get her a drink from the kitchen

I was really curious to see just how much Anna could hold, but she was clearly drained dry by this point, so I decided to get her a drink from the kitchen. I rummaged through a cupboard, finding the largest jug we had, and filled it up with ice cold water from the fridge.

I returned to my drunken housemate, getting on my knees in the puddle of yellow-tinged water around her. I shook her shoulder gently.

"Anna," I said clearly.

"Mmm?" she groaned, eyes still firmly shut. I shook her again.

"Anna, you need to drink some water, it'll help with the hangover tomorrow."

She made another noncommittal sound, but still opened her lips for the jug when it was offered. Eventually, with a lot of coaxing, I got her to drink the whole thing, easily two litres. She gasped when the last of the quenching water passed her lips.

"Stay right there, okay? I'll be right back." She didn't seem to hear me, head already lolling to the side.

I filled the jug to the brim again, and ran back to the bathroom. With some more persuasion, Anna took a few sips. I tried to offer more, but she started muttering and shaking her head slightly. Looking down between her spread legs, I could see her bladder starting to bulge pleasingly.

"Just a little bit more," I said, pressing the jug to her lips again. This time she accepted, and gulped down a decent portion. She moaned, this time a long, drawn-out one that carried on for a while. Her hips were writhing desperately, her tummy contracting. I knew she was about to burst again, so I just stepped back and watched the show.

It began with a slight trickle, running down the spread lips of her sex. This grew into a steady stream, flowing over her open thighs and pooling around her arse. Soon, an arc of deep gold liquid shot free of her urethra and splashed against the far wall of the shower. Her hips pushed forward desperately, bucking with every spurt, lifting her arse right off the tiles.

I dipped my hand into the stream, soaking it in Anna's salty spray, and wrapped it around my swollen shaft, jacking off without restraint. The night's events had kept me on edge for so long, my cum was building up in my balls within moments. I kept pounding my fist down my shaft, closing my eyes and throwing my head back as a heavy load of cum shot out, coating my hand and spraying across the shower cubicle.

Coming down from my orgasm, I opened my eyes. Anna was staring up at me through bleary eyes, and expression of confusion on her face. There were streaks of white across her forehead and cheek, and running up into her hair. As she saw my still cum-covered hands, her eyes opened wide, and her mouth dropped in shock.

"Anna, I'm sorry-" I began.
