A water bottle [piss]

“Aha!” Riley finally chirped. “Found it!”

Triumphantly, he held up… a cheap plastic water bottle, bright pink and about half-full.

The pink tint of the plastic obscured the liquid’s true colour, but from the way it frothed—and the way Riley’s little bulge visibly twitched within its cloth confines—Kirk felt he had a reasonable idea of what made it so valuable.

Riley gave a happy nod. He flipped open the lid, and breathed in the smell of it. “He’s so good to me…” he sighed contentedly.

“Woe is you…”

Riley grinned. “‘Course… you could always top it up for me…”
