Your roommate is pissed that you tracked in mud and insists you clean it up right away.
Still half-asleep, you grab the vacuum cleaner and fumble with the buttons. "Man, I don't even know how to work this thing..." you say, rubbing sleep from your eye.
"Well, you can start by plugging it in, dumbass..." your roommate says.
You plus the device in and get to work. You feel a little strange, but at first you think that's probably because you're barely awake. After a few seconds of vacuuming though, you feel as if you were punched in the gut. You look down and notice that your gut and shoulders have literally caved in...in fact, your whole body has shrunk. "I don't feel so good..." you start to say, noticing the high pitch of your voice.
"No excuses..." says your roommate, "I just bought this vacuum at the mall yesterday, so don't try to get out of this by telling me it's broken, or clogged, or anything like that, got it?"
You try to glare at your roommate, but you can only smile. "Of course, babe" you says sweetly, "I actually like cleaning up!"
With your next push of the vacuum, your shoes push up into heels. Another push, and your hips push out to give you a sexy butt. Another two pushes coincide with breasts pushing out from your chest.
As you suck up the last of the mud, you flannel shirt balls up to reveal your slim waist, and your jeans roll up to become a pair of tight shorts that show off your long, womanly legs.
As the last bit of mud is sucked inside the vacuum, the last bit of your manhood sucks inside your body, making you a complete woman.
