"OK Kristen, this is how it's going to work," you shout to your giant slave. "I'm going to shrink myself down very very small at the edge of this table, and then you will strip nude. Once you're done, you will hold your finger out at the edge, and I'll climb on. You will ensure I stay safe at all times. You will then lie down and hold your finger in front of your pussy for five minutes so I can admire you. You will then shove me in as far as you can. After that, you will call Kevin and invite him over. Make clear that he's there to fuck. When he comes over, fuck him as hard as you can while I'm in your pussy. We'll figure out the rest of it from there."
Kristen gets a horrified and disgusted look on her face, but you don't care. You could have forced her to break up with him or put her hand in the blender, but instead you chose to be nice. You proceed to the next step, walking over to the edge of the table. You pull out the gun and shrink yourself down, very far down, to the point where Kristen is bigger than any skyscraper on earth. You will be dwarfed by the tip of her finger at this point, which is fine by you: you want to be small enough that Kevin won't notice you're inside her pussy when he's fucking her.
Kristen's strip performance is amazing. It literally blows you away: a few times when she swoops off a piece of clothing, it creates an air current that's strong enough to push you over at your size. You still enjoy the experience though, and soon enough Kristen's upturned fingertip is level with the edge of the table. It's time to hop on.
It's a little terrifying riding on her fingertip as Kristen carries you to her bed, but you know that at your size you're more likely to be blown around by air currents than plummet to your doom. Still, it's a strange feeling, and you're happy when she finally lies down. You're even happier when she places you in front of her pussy. At your size, her pussy itself is the size of a skyscraper, and you admire each piece of it while her scent washes over you. You realize quickly that five minutes isn't enough for this phase, but that's what you told Kristen and you're far too small to talk to her now. Eventually your time is up, and she moves you in. You're a bit concerned that she'll crush you against her pussy, but there's enough give that you slide right in.
Soon, it's totally dark, and you're surrounded by Kristen's scent and wetness. You can't see a thing. You stay there for a while, reveling in the fact that you've truly done it, and you're actually inside Kristen's pussy now. You roll around, you lick, you make pussy juice angels. It's fun, but eventually you get bored. Just as you start to explore, you feel the vibrations of Kristen speaking.
Kevin must have arrived.
