Go big or go home!

Seeing actress he had a crush on reduced to a street whore had shocked Sam. But if he could ruin a person then he should be able to build them up as well.

There were a few films to pick from that featured women with powers that fueled the transformations. There was one that had two women in it going back and forth about how great big boobs were as one made them both grow. Sam had the perfet duo to swap them with. 10 minutes later sam had two new models Taylor_Swift.save1 and Katy_Perry.save1. Sam was curious how the program would handle putting two celebrities into the same video. After swapping them in, Sam hit Transfer and watched the magic happen.

Katy Perry in a bright blue and cotton candy pattern dress was standing face to face with her social media rival Taylor Swift in one of her tight white tops and black short shorts. "You know," Taylor said. "I bet that if my boobs were as big as yours I would have more followers than you."

Katy shrugged and rolled her eyes. "Are you still on about that. Who cares who has the most followers."

"Easy to say when you have the most."

Katy gave a mock shocked face and then smiled. "Yeah, you're right."

"It's not fair. I'm just a famous as you are but my lack of cleavage is killing my follower numbers."

"Ok, so you know how I got my boobs right?" Katy started.

It was not Taylor's turn to roll her eyes. "Not the prayer story again."

Katy waved her hand dismissively. "So I wasnt telling the whole truth." Taylor look at the other singer with interest. "I really asked God for to let me choose how big my boobs grew and I bet I can make yours bigger."

"Katy please, now is not the time to tease me like that."

Katy lifted up one hand, held it like she was going to throw a ball and said, "like this?" And threw her hand out at Taylor.

Taylor suddenly let out a moan as the sound of gurgling filled the air as her breasts started to grow. Gasping for breath, Taylor watched in shock as her breasts swelled filling and pushing out her top to its limits. Arousal and pleasure grew with her boobs and soon Taylor's hands were all over her new larger breasts. "Oh my God! What did you just... how can you do that?" Katy just smiled and blew imaginary smoke off her finger gun. Squeezing her new tits Taylor let out another moan. "That felt so good! I can't belive you can do that."

"Well, I can." Still smiling ear to ear Katy admired her handy work.

Giddy from pleasure Taylor walked up and thrust her chest out to Katy's breasts to compair their size. "Wow you did it! We're the same size now." Doing a sexy little swaying dance Taylor's hand felt up her body until they were again squeezing and pinching her sensitive nipples that were poking out from the stretched fabic. "No complaints when I steal all your follower, alright."

"Don't you worry I got that covered." With a flick of her wrist Katy send a wave at her own chest and the gurgling sound returned as her breasts began to swell. Since she was expecting it Katy held her moans back but just bairly. She bit her lip and held her arms at her side to keep from kneading the sensitive flesh as as they grew. A gasp did escape as the growing breasts started press together as they filled up the dress making the latex groan as it streched. When it was all done Katy Perry stood there trembling with arousal and tits that were twice her original size. The latex did nothing to hide the large stiff nipples or the swollen areola around them. "I forgot how good that feels."

"Hey I thought we were going to be the same size!" Taylor said clearly mad at the betrayal.

"Ok, just give me a second." Katy said shaking her head to clear away the cloud of horny arousal. As she shook her head, Katy's larger breasts picked up the motion and they bounced and swayed hypnotically. Taylor couldn't help but stare. "Ok, ready?" Katy asked. Taylor, only half listening nodded.

Taylor's mind was rocked by the second unexpected wave of growth. The pop singer moaned openly as she held her growing breasts. "Oooh, this feels sooo good." The white top Taylor was wearing started to groan as the fabric neared its limit. The shirt started to ride up revealing Taylor's toned core and a hint of under boob. A mischievous smile appeared on Katy's face as she threw a second blast at Taylor before she was done growing from the first.

"Katy!" Taylor yelled. "Not another oooOOOone." As the growth picked up speed Taylor started to gasp and moan as her breasts stretched out her shirt to its adsolute limit. Under boob was impossible to hide due to how high up her shirt had ridden. "This might be too much." Taylor said breathlessly.

"Nonsense, they look fabulous." Katy said stepping around to Taylor's side to admire her profile.

"Why did you do that? The second one."

Katy reached up and gave one of Taylor's breast a squeeze causing the women's knees to weaken for a second. "I couldn't resist seeing what two could do." Katy replied. "Besides you look fantastic now. Just imagine what your numbers will be like by the end of the week."

"I know they look great but I can't see my feet."

"That didn't stop me."

"Your boobs only blocked your feet when you were laying down. I can't even see where I'm walking Katy."

"Fine, you want me to shink them down a little?"

Taylor was shocked all over again. "You can do that?"

"If I can make them grow why wouldn't I be able to shrink them back?" Katy said. "With out the shrinking I would have been stuck in my room since high school."

"Makes sense," Taylor said. "No, I'll keep them for a little while. Maybe snap a few photos to show my agent...hey, we should match. For the photos I mean."

Katy Perry's smile lit up in anticipation. "Ok gimme a second." Clearing her mind again Katy launched anothe wave at herself. The latex dress groaned as the tit flesh inside it swelled again. Quickly growing to the size of her head, Katy Perry's breasts began to rise up like dough. When the growth stopped there was a hint of darker color as her areolas almost peeked above the edge of the dress.

"Are we the same size now?" Taylor took one step forward and miss judged the small distnace between the two mountainous sets of breasts and her tits collided with Katy's. The collision had enough **** to make Katy take a step back and cause both chests to bounce. "Sorry."

"Don't worry we're the same size now." Their breasts might have been the same size but on Katy's smaller frame it made her breasts look bigger. "These almost look too big on me. They look great on you though." Reaching out again Katy held Taylor's breasts in her hands.

A lust filled gaze on Taylor's face showed that she was no longer thinking about social media or photos. "Don't say that, this size looks better on you." Taylor reached out to return the favor and she began to stroke and squeeze Katy's breasts.

Katy let out a sighing moan. "Yeah, thats it." The two women slid closer until their breasts were softly pressing into eachother. "Just keep doing that."

"Photos can wait." And the camera went dark as Katy Perry and Taylor Swift started to fondle eachothers breasts in earnest.
