"So, what happens now?" you asked.
"Simple, silly! I stand here, and you climb me. When you get all the way up to my shoulder, I'll give a reward!" And she smiled.
Sixty-four inches had never seemed like a long way before, but now it was more than 21 times your height. So, in real life, climbing cute Kate would be like climbing a 100 foot limbless tree with boobs! You start, obviously, at her feet. She's wearing sandals, which makes you kind of nervous, because it seems likely that if you tickle her foot, she will squash you like a bug. Carefull, you climb over one polished toenail and gain a handhold on her toe strap. Perching with your feet on that leather ridge, you reach up as far as you can and just manage to grab ahold of her metal buckle with both hands. one benefit of being a shrunken boy is that you don't weigh very much, so you easily hoist yourself up on the top strap. Yeah!
Looking up, you're tying to find a path you can navigate along her jeans. "Thank God you aren't wearing short skirt!" you yell.
"Are you sure about that? Think of the great view you would have from down there!" She smiles and giggles.
Immediately, your mind starts to wander, as you imagine yourself somehow managing to get inside her skirt and rub your entire three inch self up and along her slit. Maybe later. One grab and hoist along a crease in her denim, pressing your feet into the seam for leverage. When you finally make it up to her waist band, you're dripping with sweat. Worse, though -- because you were shrunken, you are also naked, your clothes having fallen off and onto the floor.
The easiest course is between buttons on her shirt: you can hold onto the outside of the fabric and climb along the buttons themselves. The downside is that, because Kate has lovely, full, ripe breasts and is wearing a thin shirt, you are hangin out in a risky place -- about 50 feet in your world -- above the ground. So you stay on the side of her shirt, and marvel at her huge tits above your head. You rest with one foot on a button and the other in her belly button, and eventyually you climb up between her breasts on the cloth of her bra. The cup of her bra allows you shimmy up higher, one foot outside on the cloth, the other inside against her beautiful pale skin. Your erect penis -- all 1/3 of an inch long at this point -- rubs along the edge of the brassiere, and you start to feel totally aroused, imagining the view you will have of her nipple and areola in just a minute or two more of work.
"Careful, there, big boy," she jokes. "Don't get too aroused and leave a stain!"
In no time, you have shimmied (erection and all) up her bra strap and are sitting on her shoulder, looking down at the gap between her titty and the bra cup.
"Good boy," she says.
"What's my reward," you ask, panting.
