"Hey," she says, "we're not just going to stay like this, are we?"
"Balloons?" you reply. "Um, as far as I can tell."
"No - we're not just going to stay on the ceiling like this, are we?"
"Well, no - what next? The floor? The sofa?"
"No, I mean - we're not just going to fuck forever, are we?"
"Well... no... I guess not."
"So what are we going to do today? Tomorrow?"
"...I dunno... I guess the same thing we do every day," you say.
"...so I should just go back to sell balloons as a balloon?" she asks.
"Sure, why not?"
She laughs. "Well, we should probably get used to taking these out in public first."
You laugh in response. "Naked?"
She laughs more loudly. "Of course not! We're about the same size. My clothes should fit you. I think we can find something to weigh us down."
"Don't worry about that," you say, and the two of you float gently to the floor as you increase your density.
"Okay," she says. "But we do have to do something about... that." She doesn't even need to gesture for you to know what she's referring to.
Soon she's wearing her usual pants and blouse, whereas you're wearing a matronly-looking dress whose owner hardly wears it, chosen to be loose enough that your penis, held to your thigh with electrical tape, won't be too obvious. Your skin is still blue, and hers still red, and the texture will make it obvious to anyone who looks closely enough it's not just paint.
Hand in hand, you smile at one another, and head out into the street.
