"Here! I know how it looks but... I need you to put it on!" Alice says finally handing him a collar. "Honey... how would it help?" asks confused... Her parents soon will be there, and she wanted him to put on some kinky collar?
"No time for it!" says strictly and puts it on his neck. He touches it confused, not knowing what's going on here. He was completely naked, with just a collar on his neck, now it looks even worse, than if he would just put his clothes back!
"Just calm down please, it will be fine, I promise" she says... petting him? It feels nice, but... Wasn't he taller than her a few moments ago? "This collar... will change you into a dog" explains shortly. Greg's heart speeds up hearing it... He wanted to ask something else, but felt his tongue rolling out of his mouth!
A few seconds later, he felt himself falling forward, not wanting to fall on his face, he tries to lean over Alice, who grabs his paws to keep him upward for a little more. Paws!? He looks at his what-should-be hands to see a pair of canine paws, not his human hands!
"This is not real!" he tries to say, letting out some weird whines. Soon she puts him down, on all fours.
"Shhh... don't whine, just... play a dog you are and it will be fine!" Alice tries to calm him down, petting him behind his floppy ears. He tries to figure out what's going on panting like a dog... like a dog? He tucks his tail scared and looks around.
He notices a reflection in a mirror... A frightened dog was standing there... And he was that dog!
"My love, don't worry, everything is under control, just... play a dog, please?"
