If I may, for your fic prompt for sunday, how about like the monster of the week turns Derek into miniature size derek (in beta wolf form) and Stiles can't stop picking him up and carrying him. This is probably not a very good prompt but mini derek with little ears and a tail brings me happiness haha.
Derek blinks, and the world looks incredibly different. What happened? Did the witch transport him somewhere? He’s being smothered by some sort of enormous blanket. He feels odd, like he’s stuck in between shifts. Derek feels up his head and finds he’s got a fluffy pair of wolf ears instead of his human ones, and there’s a tail protruding from his spine.
And he’s naked for some reason. Derek pushes at the fabric, frowning at the color as he tries to fight his way out of it. Something fwips him in the face, and Derek frowns at the sign— MACHINE WASH COLD, WASH WITH LIKE COLORS—
Wait a minute.
Derek struggles, and then the huge fabric gives way to light.
"Derek is still here!" a voice says triumphantly.
Why is everyone so huge—
Derek grabs the hem of his now ginormous shirt, and yanks it over himself. This is ridiculous, what is even happening, why does he even look like this— and why is his tail wagging—
Stiles looms over him, bringing his face down and grinning. “Hey, the witch shrunk Derek,” he says. “And he has a tail!” Stiles says delightedly.
