Do something nice for Sammie

"Hey, I've got a funny idea," you say. "Wait here."

You're back before she's done saying "Okay."

"Got it!" you say, flaunting the object of your endeavor. "Now, take off your clothes."

"What?" says Sammie, her face falling. "Hang on, you said--"

"I really didn't say anything," you say. "Besides, you'll like this. Trust me..."

She doesn't get much of a choice as you yank her dress heavenward and tip her re-nuded body over your knee. You see fit to spit-shine the "S" off of her left buttock before you continue with your mission.

"Eek!" says Sammie, still catching up with her predicament. You have to pin her in place with your free arm as she struggles to escape your lap. "C'mon! Do you have any idea how embarrassing this is?"

"Give me a second!" you say.

"Give me back my... Please tell me you're not cleaning the paint off my ass with your spit!"

"Stop squirming so much! I swear, in a minute you'll be thanking me."

"Can you at least ease up a bit with the rubbing? It's still stinging from... before."

"From before, when that endearing little boy spanked you?"

You can feel her buttocks tense at the word. She buries her face in her hand with a poorly repressed groan.

"For somebody who was spanking his first woman, he really stepped up like a champ. Didn't he?"

"Could we stop talking about that?"

"Sure. We're almost done here."

She gives a yelp as you deliver three swift slaps to her ass, spanking into place a cartoon of a naked woman with the caption "I was stripped by someone awesome!"

"What is this?" she asks.

"It's an adhesive spell. Once I apply the counterpart, it will take effect. Just answer me this: Which one of these girls has the best boobs?"

"That would be Rellia," says Sammie, pointing to the generously-endowed red-head.

"Got it."

You spank an identical adhesive spell onto the ass of the buxom girl, getting an angry scream for your trouble. As soon as its in place, Sammie's breasts balloon up until they take on the appearance of Rellia's, and Rellia's shrink down until they resemble Sammie's.

"No!" says Rellia. "NO!" She begins frantically rubbing at her ass, unaware of how stubborn these spells are once they're in place.

Sammie, meanwhile, is inspecting her new boobs. She gives them a squeeze, lifts them, and then lets them bounce back into place. She's so fascinated that she hasn't yet remembered to put her dress back on.
