Strip her, let her orgasm, shrink her

You silently stand in the doorway to the basement, watching Gabriella's cute ass hang in the middle of the room. She starts to wake up and groggily shakes her head.

"w-w-where am I?", she sleepily says.

You walk up behind her, she hasn't noticed you yet, and give her a sharp slap on the ass. She tries to jump, but you didn't give her much room to move. Gabriella starts to struggle against her bonds, but it is no use, you tied her up good.

You grab your knife out again and press it against her pussy, slicing her panties off. She lets out a soft moan but then remembers where she is.

"Hey! Let me out of here you creep" she angrily shouts. Of course, you can't have your blonde little bitch shouting for help and getting the attention of your neighbors or your girlfriend when she gets home. You roughly shove her panties in her mouth along with a bit of tape to keep them there. Gabriella can no longer make any real noise even though you can still here her angry, muffled threats.

You cut off her bra as well and start to grope her boobs. You squeeze them and pinch her nipple. Gabriella tries to sound mad through her gag though you can tell she is starting to like it even if she doesn't want it to look like it.

You kneel down and start to lick her pussy, trying to give her one more orgasm in her full size. Gabriella moans again as you wedge your tongue in between her clit and her pussy. It does not take much of your tongue flicking across her, she orgasms fast. Squirt pours out of her pussy as she limply hangs there, with no energy left.

"Now Gabriella, the real fun is about to start", you say as you get up and grab some of your formula. Her eyes are wide as she has no idea what you are about to do. "How about we put some of it on your round ass boobs hey?" you say while slowly walking over to her. She squirms against her bonds, but of course, you tied her up well. A single drop of the formula on her exposed breast shrinks her all the way down to six inches tall.

You are still a bit amazed that your formula worked, though she is outright terrified. You pick her up in your fingers and watch the naked girl panic on your hand. She is now even shorter than your dick and you couldn't be happier.

You then hear Kate enter the house and panic to clean up after yourself. You hurridly shove Gabriella into a test tube, she was still too terrified and confused to move, before corking it and shoving it in the cupboard. You quickly hide her clothes and come up out of the basement to see Kate, you just need to act like you aren't hiding anything she shouldn't see yet...
