"Ok hun, lets go into the small room, I have an idea!" You say with a wink. She winks back, causing her cheek to jiggle slightly. With laberday breath and earth shaking footsteps she walks slowly to the small room.
Inside the small room is a computer console sticking out of the ground and a strange ray gun hanging from the ceiling, a small X on the floor within its path. Putting two and two together she struggles to the X and plops her huge ass onto it. You brace the console as the whole room shakes like a small earthquake. Your girlfriend giggles quietly before apologizing. You then make the selection on the computer. "What's this idea of yours hun?" She asks scratching her massive tummy "I hope it's naughty"
"Oh, you have no idea babe! I'm gona play with all your lushes new folds!" Then you slam the 'fire' butten and a beam fires from the gun and hits your girlfriend square in the chest. She glows for only a moment, then you see it happen.
Slowly buts surely she begins to shrink. Her body staying just as fat and covered in folds only smaller. She starts giggling uncontrollably as the sensation tickles her fat.
As you approach her you start to take off your cloths. When she was sitting down she had been head level with you, but now she only comes to your neck. As you strip off your shirt she's now at chest height. Half way between the gap you start to undo your belt and pants she now sits less then 4feet in height. You now stand infron of her as you take off your underware and your stiff erection springs from its confines, she reaches for it and pulls it into her mouth at a perfect 3feet tall, she laps at your massive member (too her) as long as she can, her small mouth can barely suck the tip and soon finds it hard to reach as she's still shrinking.
Now less then a two feet tall and just as wide she looks like some kind of strange toddler reaching her hands and grabbing at air to reach your cock.
Her shrinking finally stops at just under a foot, she looks like a partially filled basket ball. You reach down and pick her up under her arms like a child, her fat flabby legs kicking in the wind. To her you look like a gient, lifting her hundreds of feet into the air. You brink her close and kiss her tiny head. She still looks to be 792 pounds but to you she's a little over 15. "So is that all, a little head and your done?" She ask. "Oh babe, you know me better then that!" You tell her as you turn her around and bring her to your crotch.
"Wow now cowboy! You can't do this!" She screams! "That thing of yours is the size of a bus!" "I know right, your gona be so tight!" Without another word you plunge your dick into the soft folds of your miniature fat girlfriend. You set up the change to make it safe without her knowing.
As you plow into her like a pocket pussy she screams out in orgasim, in a high pitched squeal. You lie down and thrust against her weight as you pinch at her teeny-tiny nipples and massage her folds until you cum filling her pussy with your seed and almost shooting her off like a rocket.
You pull her off and set her on your chest, she's panting uncontrollably as at you, making her bounce up and down.
She finally catches her breath "that was naughty!" Leaning into your chin and giving you a kiss.
