Yes, complete the change

“Perfect” she said, “Now, give yourself some clothes for your top and then change it!”

You focussed and felt a bra starting to form around your upper torso. The straps appeared from nowhere, and cups started to form over your nonexistent breasts, growing and growing.

“Wait a minute” Rebecca said, “How big are they growing? Are you sure you haven’t given yourself massive tits?” she asked.

“I swear,” you said, “According to the magic, apparently, I inherited a gene from my great grandmother, who had massive tits.” You said matter-of-factly.

“I believe you” Rebecca said, “But how large are they going to be?”

“34H cup” you said, sounding surprised.

“FUCK ME that’s massive, especially on your teeny tiny frame” Rebecca shouted.

“yeah, its going to be interesting living with them for a bit” you said, right as a top started to form over the bra, a red top which showed a very small amount of cleavage.

Your body started doing its final changes now, as your stomach flattened out and took on a more feminine shape, and your pecks started gaining some definition. Your nipples started to extend, growing by maybe a quarter of an inch, and your areolas started to grow, resulting in a darkened disk about an inch and a half in diameter. Your new breasts began to grow at a steady rate, fat and muscle bubbled around on them, pushing them out to a small A cup, then to a B, then rather quickly passing C and D slowly down at DD for a pause. Now they fully exploded to each size, forcing you to push your chest out and let a small moan escape your new female lips, in your new female voice. After thirty seconds they reached their full size of an H cup, and then they jumped and jiggled around for a bit, positioning themselves within your bra and shirt.

When they finished you got up to admire yourself in the mirror, watching Rebecca staring with wonder behind you. You were now a very short girl who, from behind, looked like any old short but cute girl, and actually, you even looked like that from the front, till people would notice your rather massive breasts, when you would suddenly take on the guise of a sex bomb as well as a cute girl.

“Fuck me” you whispered,

“Trust me, there are plenty of people willing to do just that” Rebecca whispered back, causing both of you to laugh very loud. “What’s your new name?”
