Her tits of course!

“Well don’t take this the wrong way but your tits are too small, that outfit is designed for someone with a healthy chest” Dave replied.

“I know” Kat answered sighing heavily as she slumped in a chair, “But I can’t afford any plastic surgery” she added in a dejected tone.

“Plastic surgery isn’t the only option you know” Dave said as he moved to sit next her.

“True but it’s the only guaranteed method, I can’t wait six months on the hope that some chemical might work” Kat replied, leaning in close to Dave.

“Well I have a method that’s pretty full-proof and works quickly” Dave offered, making sure his grip of the bone was secure.

“Really?! How does it work?” Kat asked sitting up with hope in her eyes.

“No no no, that’s a trade secrete” Dave responded with a friendly smile, “So do you want me to develop your chest?” he asked looking into her eyes.

“Oh god yes! Please give me a bosom to be proud off!” answered Kat getting even more excited.

“Ok then just lie down, close your eyes and relax” Dave instructed, Kat lay down, resting her head in Dave’s lap after closing her eyes she took a deep breath.

“Ok I’m ready” she said softly, Dave tucked the bone behind his ear and cleared his throat.

“Ok here we go” he said quietly, he placed his fingers at Kat’s temple and lightly rubbed in a circular motion, “This’ll activate the growth area of the brain” he said softly.

“Mmm it feels nice” Kat replied almost in a trance. After a few minutes Dave moved onto stage two.

“I’m just going to place my fingers on your boobs” he commentated as he placed his finger tips on each breast. “Hello Mrs Left-Breast” he said as he gave the tit a little shake, “Hello Mrs Right-Breast” he continued giving it a similar shake.

“You’re just messing about!” Kat said giggling slightly at Dave’s chant.

“I’m being deadly serious, this is how it’s done” replied Dave as he started to massage each breast, “By the powers that be I command you to grow” he said lightly cupping each breast from above, silently making a wish for Kat’s tits to grow larger.

“Mmm something is happening” Kat murmured as she felt a tightness in her chest.

“Yes it’s working, your breasts are growing, try and stay relaxed, the more relaxed you are the bigger they’ll grow” Dave replied softly, Kat’s boobs already filling the space that was left between his hands and Kat’s original sized tits.
