You're soon snoring.
Richard looks up from the half eaten Klondike Bar. He's covered with your cum, chocolate and vanilla ice cream. He walks over to the cage, and reaches through the bars and undoes the latch. He looks over at you sleeping form, and shakes his head. He exits his cage, and shimmies down the lamp cord to the floor. He wipes the goo off himself with one of your socks. Then he heads over to your computer desk. He uses the open drawers like ledges, and rock climbs up to the desktop. He heads straight for where you set your watch earlier.
"Hm, he said something about me evolving to fit my environment and being furry because I didn't have clothing. He lifts the watch, it's weighs a friggin' ton for a tiny man Richard groans softly, but carries the watch to the cushioned chair and lowers it on to the cushion, and then drops down on to the chair himself. He lowers the watch to right about your now soiled sock and drops the watch on it. Then he lowers himself and drops the last few inches (which seem like feet) himself. He then drags the watch over to your clothes closet. You left the door part way open. He finds and arranges a t-shirt, jockstrap, shorts and socks, and drags the watch inside them. Then he advances the watch hands back and forth ever so slightly.
Oof! Thud!
He banged his head on the wall of the closet as he grew into your clothes. His feet kicked the closet door open. Richard heads to the mirror with the watch in hand. His face is familiar, but not quite his own. He looks at the door. He's a few inches shorter than he should be. He pulls back the waistband of your shorts and curses. "Extra Small Jockstrap! No wonder I'm a runt!"
He glares at you snoring away. Then he notices the dog collar and leash. He quietly grabs it, and stalks over to your bed. Gently, he pulls back the covers, and works your boxers off your body. When you're naked, he fastens the collar around your neck. Then he gently lifts you out of the bed, you mumble half awake. He says, "Hush, lil puppy. Go back to sleep."
He sets you on the floor, and aims the watch at you, and adjusts the dial. You're reduced to some sort of reptile on a leash. A big iguana like creature. Richard then advances the hands slightly until he decides you are a proper canine. He secures your leash, puts the watch inside his jockstrap pouch with his family jewels, and lies in your bed and falls asleep.
You wake to discover you're a dog. You see someone sleeping in your bed, and you see that Richard's cage is empty. Damn, he must've gotten out and used the watch on you. You gnaw at your leash, but its designed to resist that. You pull on the leash, but he secured it to the doorknob, You yap loudly and angrily.
The new Richard stretches and sits up.
"Shut up! After what you did to me, you're lucky your not mold or a fly. Now boy, I'm going to take you to the pet store and get you properly vaccinated and licensed. While you're there, I will go to the gym, change into my own clothes, and see if this screwy watch of yours will give me back my own body. If it does, I'll be back for you. If not? Well, I suppose the store will keep you for 30 days, and then fix you and sell you. So you better hope this works."
You whimper. He pulls on your leash. You sit and resist.
"Okay, let me put it to you another way. You either go to the pet shop with me willingly, or I call animal control and say that there's a stray dog in the dorms. You know what happens to stray dogs in this town?"
Your eyes go wide. You whimper, but advance slowly with your head and tail drooping.
He has you kenneled, and then talks to the clerk on the other side of a glass window You cannot quite make out what he's saying. Something about obedience school, maybe?
