Zoe puts some junk in her trunk

"Hmm this is great but I'm feeling a little top heavy." Zoe says "I wonder if this thing can give my booty a boost too?"

She takes careful aim in the mirror and zaps herself again. The effect is immediate. Her small firm backside ballons out straining the seams of her jeans. Zoe laughs giving her brand new bubble butt a playful slap.

"Oh yes" she giggles "Beyonce eat your heart out."

You can't help laughing as she dances around twerking her ass and shaking her boobies at you.

"Damn, sis" you chuckle "if this college thing doesn't work out you can alway try out to be a stripper."

"Ha, you'd like that would you" she smirks "your sweet innocent little sister shaking her goodies for a bunch of horny dudes."

"Like you wouldn't be all over that" you say "I'm not going to be the one to tell mom though, that would all be on you."

She chuckles and pretends to be weighing her options.

"Hmm, it's true she would definitely kill me and I'm far to young and sexy to die yet..." she shrugs "Oh, well looks like my academic career will have to continue a while."

You pour her a coffee and the two of you chat about what to do next...
