Takes Harley to Selinas own private fat cave

Scooping her thin friend up in her big fat arms, Fat Harley carried her away as she drifted off to a stuffed sleep, passing out from the food coma she'd managed to give herself

"That's right little Harl, Just you sleep, I'm gonna take you somewhere nice and safe" Fat Harley cooed while stroking her smaller self's hair, smearing her face with greasy remnants of their meal

Waddling away from the booth Harley went to a service elevator at the back of the restaurant with the words "VIP's Only" strewn across the doors, entering her access code into the keypad she entered the lift and pressed the button that would lead her to the head honcho of this establishment and renowned play girl, Selina Kyle.

Thin Harley awoke softly and peacefully, her distended gut being rubbed by her fat self as she stretched out to take stock of her surroundings, they weren't in the restaurant but they weren't anywhere that she'd been previously either, a big sprawling underground station was all around her, she was she noticed on a surprisingly clean but large mattress, in the centre of a ring of vats and barrels all of which had various labels and nozzles all over them and strange scents wafting from them as well.

"Where are we?" Harley asked her fatter counterpart

"I've brought you somewhere where we can really pack some meat on those skinny little bones sugar" was the reply she got, as the floor began to shake at the approach of some hulking bulk out of the shadows behind them.
