Amazingly well

She looks at you in confusion, but let a surprised moan come out of her red lips. You look in amazement, as her boobs start growing bigger and bigger while keeping their firmness and perfect round shape. Soon, they are as big as melons and still going. You wait a few more inches, then order "Stop it now, that's enough."

It instantly stop, and your new servant seems relieved. "How do you feel? Did it hurt?" you ask, somewhat concerned.

"Not at all, Master. It... actually felt good. However, I'm quite hungry now. I think... this..." she points at her now gigantic chest "... might have sucked out my body fat in order to grow."

You smile. "We'll give you something to eat as soon as we're over here, then." you assure her, much to her relief. "By the way, you should be proud of this beautiful body you have. Especially this chest your benevolant master gave you."

She smiles back, true happiness clearly shown on her face. "Yes, Master. I don't know how I could ever thank you for this." she says while caressing her tits.

"Ho, I have a few ideas." you answer, resisting the urge to fuck her right here right now. "Anyway, since you like your body so much, you should stop hiding it with such untasteful garments."

She looks at her clothes in disgust "You're right, Master. Should I go around naked, from now on?"

You laugh "No, no, you don't need to go so far! At least not when you're in a situation in which being naked would be... inappropriate. But you should show off more. Wear tight low-necked shirts, but with classy jackets, short skirts, maybe sexy stockings... High heels, too, and maybe jewelry. An expensive golden necklace with a gem pointing out to this big chest you're so proud of, for example."

She bits her lips, blushing. "It... I would love it, Master, but... I'm not sure I could afford it."

"Hmm... I'll think about it. The point is, dress sexy. But classy, too. Don't turn into some slutty teenager."

"Yes, Master."

With all of this settled, you start working over her body to make it trully perfect. You make her skin entirely smooth, permanently remove all of her hair below the neck except for her pubic hair which you shape into a triangle and make sure won't grow any longer. You make her lips slightly fuller and her hips slightly larger, but you know it was more vanity than necessity.
