This is what happens when you start getting addicted to the shrinking experience.
You start slow. You only reduce yourself to something like 1m. Nothing much.
Then it's 50cm. So you can sneak into your absent wife's shoe collection and sniff her scent. Hell, you do that again when you're 15cm. You can masturbate in them and it feels so perfect... Eva won't find out.
The trouble starts when you hear the water running and you just know your hot step daughter is getting naked in the bathroom with the door slightly open.
You know she's your step daughter, that you're supposed to be the better man and try to educate her right, but the thought of seeing her in all her morning glory...
Before you can further question yourself, you're 3cm tall. This is the smallest you've been.
She's still flexing in front of the mirror, like a giant monument to both sexes. Most importantly, she's distracted. Good. This is your chance.
You climb up the pipe leading to the faucet and lightly drop on the side of the tub.
That's when everything goes wrong.
Kimmy's hair whip you from out of nowhere and you're flying for a very quick second before you break the surface.
She merely looks down, but you're under the foam screen and she shrugs to the sound she thought she heard.
Your near invisible monk-like head pops up from beneath the bubbles just in time to see Kimmy's foot entering the tub. Minor waves lull you around as she slowly tastes the heat with both feet, then slowly kneels down.
Your eyes are glued to her, but when you see her enormous shaft.. somehow.. a tiny boner forms between your legs.
Suddenly, you just want to touch her, and when she will save you from this predicament, you can just invent some bollocks, like "the machine misfired, I was going for a bath when I started shrinking". Can't go wrong with that, right? She'll believe you.
You start to frantically swim towards her bus sized cock....
