Pulling up to his house, Ty stepped out of Jennifer and watched as she transformed back into a person only a couple inches tall. Coughing and spitting on the ground, Jennifer looks pretty dirty after the dusty ride home. She pushes herself off the asphalt and glares at Ty while covering herself, apparently newly defiant now that the shock of what happened is over. Ty walks over to her, and as he does, she flattens, gaining a plasticy sheen. From her head sprouts a chain with a ring on the end. Ty grabs the keychain and hooks it onto his keys before walking inside.
Inside, he's immediately greeted by his foster parents, "Hey Ty, it's your turn to vacuum the living room, Dustin's mowing the lawn this week." yelled June. "Alright mom," Ty said, "Just let me throw my stuff in my room real quick." Ty quickly jogs up the stairs and shrugs off his backpack, then heads back downstairs. Pulling Jennifer out of his pocket, he grins at her as her eyes widen, then says, "I think I need a vacuum."
Tossing her on the floor, he watches as she first returns to three dimensions, the chain disappearing. Pushing herself up, she stands and glares at Ty, opening her mouth to speak only to fall again as her arms and legs rapidly disappear. Jennifer's feet quickly curl into small wheels and her breasts follow suit as she grows. Her hands curl around her shoulder, becoming latches and buttons. Meanwhile, her neck elongates, snaking several feet. Her head angles downwards and flattens as her mouth enlarges to cover most of her face. Lastly as she reaches her final size, a cord snakes out of her pussy.
As Ty reaches down to grab the cord, he hears Jennifer, "Don't you dare..." Smiling, Ty grabs the cord and gives it a tug, taking happiness in her gasp. He pulls the cord over to an outlet before plugging it it, eliciting a louder gasp from Jennifer. "Please, stop Ty." She says as he walks back over to her, "I know your a nice person." He stops and grabs the handle, "I am," he responds, "to people who are nice to me, maybe after this day I'll decide you've learned your lesson, then we can both see what we can get out of this. But for now..." He flicks the switch, opening Jennifer's mouth and activating the vacuum.

Fifteen minutes later, Ty decides the room's clean enough and shuts down the vacuum, then reverts Jennifer back to her shrunken human form. He watches as she shrinks back down, then starts a coughing fit. She hacks and wheezes on all fours for over a minute, then manages to gasp, "Help..." before passing out.
