You're improving Freddy at first.

"Deal!"

You lean to the girl and kisses her wet lips. She opens her mouth and your tongues swirls against each over.
While you're kissing, you pulls off her panties and skirt and moves Freddy from the sofa to your lap. You take off her top and Freddy unclasps and throws back her bra.

The cheerleader wearing only knee-socks is sitting on your lap. You're squeezing her firm butt, her pussy lips are pressed to the base of your huge cock and her hardened nipples are teasing to your muscular chest.

"Ready or not, I begins."
"Yes, John, change me!"

At first, you're increasing her height, so Freddy growths to full six feet.
Then her waist-length sandy hair becomes platinum blonde and lengthens to her knees. Also, her hair has acquired the shine and increased the volume, as in a shampoo ad.

Next step: her skin becomes flawless and loses all hair below the neck, her eyelashes gets longer and richer and lips pouts to lovely shape, perfect for kissing and cocksucking, her teeth are perfectly white and wouldn't change its color in the future.

You're changing her body. next...

Freddy transforms from the fit girl to the gym rat. Her trained muscles growths bigger and stronger.
Your hands are feeling how her buttocks are inflating by strong muscles. Her quads and calves swells with newer bigger and stronger muscles. You make massive improvements to her skills in gymnastic, athletic and all needed to cheerleading.
Your hands move from firm bubble Butt to wide strong thighs. You're caressing her legs, then moves to her washboard abs and perky B-cups.

It's time for main dish.

You're fondling and mauling her boobs for a while.

Slowly, her breasts are growing and molding to perfect globes. Her B-cups turns to C-cups, then her D-cups fills your hands and E-cups pushes them out. You're trying to hold her tit flesh in your hands, but her F-cups overflows and splashes out of them.

Soon her tits growing ends, and you're fondling her perfect G-cup melons and their erected nipples. Now Freddy's jugs are one of the best in the school, only Wendy, Chery and Taylor are better endowed.
