Her slow transformation into your pet

As Emma sat down, you got to work.

"Emma, would you rather wear a sexy dog costume or nothing at all?"

"Dog costume, duh!" Emma blanched.

Her clothes morphed into a furry bikini with a dog tail, a dog ear headband, and a collar.

"Next, would you rather walk on all fours like a dog forever, or walk normally but orgasm every time you took a step?"

"The first one."

You notice her shoot her feet up on the couch, sitting similarly to how a dog would.

"You're doing great," you said. "Just two more questions. First, would you rather only be able to eat and drink out of dog bowls, or piss yourself every time you drank coffee."

"Definitely dog bowls."

"Finally, would you rather forget everything about your past life, believing yourself to be my horny pet dog forever and ever, or have a desire to fuck every man you see."

"Be your dog...."

As soon as she said that, she stuck her tongue out and wiggled her butt. She lept off the couch and lay her head on your lap, now your pet dog.
