Roomate's pet

The final screen of the Mario Kart results flashes brightly on the living room TV, cementing your crushing defeat. You toss your controller onto the coffee table with a sigh, looking over at Liam and Jason. Liam is already laughing, leaning back on the sofa, while Jason stands up with a triumphant, lazy grin, adjusting his office button-down shirt.
Well, a bet's a bet, Jason says, stepping over to the closet and pulling out a surprisingly heavy cardboard box he clearly prepared in advance. He sets it on the table with a thud, opening the flaps to reveal a sleek black leather collar, a plush faux-fur tail plug, a massive plush dog bed, a matching red leash, and two stainless steel bowls. You thought you were just getting dish duty, huh? Modern problems require modern solutions. To help you destress from the job hunt, you're officially our house pet for the week.
Liam chuckles, leaning forward with his elbows on his knees, watching your reaction. Hey, it's a total vacation. No chores, no human responsibilities. But Jason's rules are strict. Inside this apartment, you're on all fours, you wear only the gear and nothing else, you eat from the bowls, and you only bark. No human words.
Jason picks up the sleek leather collar, letting it dangle from his fingers. And remember, roommate... if you slip up, stand up on two feet, or accidentally talk, there will be penalties. We've got a leash right here, and our hands are ready for a proper spanking if you misbehave. Of course, if it gets too much, just say the word and we stop the whole game. But until then... are you going to be a good sport and let us put this collar on you?
