Hiroto bowed to his Mistress cautiously, making sure that he idolized even the tips of her toes. He was not permitted to look directly at the other mistresses in the room, for doing so would be his undoing as a piss slave. The mistress orders him to lay on the floor and wear the filthy cut piss bottle in his mouth. His aging teeth grip gnarled bottle and he waits for his fate. One of the junior mistresses stands up says that her bladder is just about ready to pop. She smiles and squats on Hirotos bottle, providing the edge a little weight so the plastic would dig into his mouth. Hiroto smells it before he could even see it a thick, pungent stream of piss thats thick enough to gasp him. It was so salty that his mouth kicked back, making him to bite the bottle even firmer. The mistress feels his distress and chuckles, taking her sweet time on the bottle before standing up. Aya the Fierce, the piss pets owner pulls him up with his leash and orders him to thank the other cruel mistresses. He gulps the remaining taste in his mouth and tastes the saltiness even in his throat. He pathetically bows, showing the embarrassing message penned on his back. He will be pulled back to his toilet duties very soon.
