Annie tries her best, but it isn't easy to beat a champ!

Annie looked up and saw the white ceiling. It was perforated with ventilation holes or some such and had built-in bright white lights installed into it. Since she was this high up now, it reminded of just how "tall" her huge boobs had now made her. She remembered this spot she always started her duels against Emma at and how the details in the ceiling she began to notice after a while. Only this time, she could've sworn she noticed details she hadn't previous times. Had her eye-sight simply improved or...? No, of course this meant she's now gone further than she had before. The realization amazed and motivated the beautiful little rabbit: She could reach the top.

The awesome sizes of the two competing women meant that the distance between the spectators and their snack table placed along the furthermost wall had shrunk considerably. Jiggling, bouncing and stretching nearer and nearer towards them was the tightly clung red and purple clothes of the fierce growth rivals. To them all, it was growing apparent that they'd need to move out the way or risk being smothered as the tit and ass masses pushed closer to them.

The rest of the office and their boss decided to move themselves and the snack table out the way. "You're both keeping equal pace, girls! But you've filled out the whole office, so we're leaving!" The shortstacked rat boss told the two tians growing in her office floor. "Do you both still want to continue?" she asked them, and both girls yelled an enthused 'yes!' back at her. And so, the competition went on, without a referee to declare a clear winner...

Annie felt herself being pushed away from Emma due to how giant both their chests now where They had started stood pretty close to one another, but now she was unsure of the exact distance she or her occupied. The sensation also hit her now of her ass having hit the glass panels of the window opposite her and the walls to her right and left, meaning she now took up the space of three walls of this entire skyscraper floor. She felt big, and also...proud.

As a consequence of space running out, her ass cheeks began to rise higher up and closer to her own back. Two beautifully colossal breasts and an almost unimaginably huge ass expanded against the floor and another equally well-endowing woman, now their only place to rise was upwards towards the ceiling. Neither woman wanted to stop, though the both now breathed heavily, panted and...moaned excitedly. The contest didn't really matter anymore. Annie desired to explore her limits...and to climax.

Diamonds of white breastflesh escaped the confines of the jacket and shirt Annie was dressed in. Her outfit had reached its limits. Annie had never destroyed an outfit with this high of a stretch rating before, and she hadn't outgrown any outfit at all in a long time either! Oh god, this felt so sexy to her. Annie grabbed as much of her chest as she could, pressing and massaging it while whispering words of adoration and encouragement into her body which growth now seemed self-sustaining. She couldn't see or hear it, but she sensed that Emma on the other side of the two colliding walls of boobiful jigglyness was doing just the same in her own horniness.

Both girls had forgot about the ceiling the both now neared, since their growths were just so pleasurable. In fact, this expansion excitement alone, along with the tugging of their now-too-small-clothes against their sensitive areas was making both women approach the competitions climax.

Strain took against Annie's small bunny skirt as it was the first to loudly *RIIIP* apart exposing all of her lower half to the cold, walls and floor. Following suit, her outfit and undies ware holding on for dear life, but it was too much for her jacket and shirt now as it gave way, ripped apart and was no longer attached to her. Emma's cat clothing had also med the same fate, as they both felt their tighter-than-tight underwear soon needing to meet the same fate as their bodies rose up towards the top of the room.

Unexpectantly, the pressure of both ladies' ass flesh which pressed against the windows of their floor had gotten too high. The glass panes didn't shatter in their place, but instead plopped out their firmaments and flew down to the streets below (no-one was under them), letting pockets of white and light brown fur bulge out their respective side of the sky scraper. Many on-lookers below took the opportunity to record the unusual sight and posted it to the web.

The jolt of movement the high-up hourglasses felt and the resulting wave of bouncing ass moving up their entire hourglassy bodies was enough to drive both ladies of the edge, as their underwear both upstairs and downstairs snapped while Annie and Emma yelled out in a simultaneous orgasm. The orgasmic pleasure resulted in surges of ass and breast expansion for both girls, as all other available space was completely filled out with their huge boobs and asses.

As the dizzying blur of confusion and joyous elation the strong climax caused Annie eventually passed, she was met with the realization of not having much room. A ceiling lamp illuminated the pocket of space her upper body occupied. She could see an endless cleavage before her, and feel a comparably impressive ass pressing upwards towards herself. She called out to her opponent, and surprisingly enough she could hear her answer back. "Do we call it a tie, Annie? I've never gotten this big before in my entire life!" the cat said. "Well, we're both as big now as a half-a-house, Emma!" the bunny answered back, "and this is probably exactly twice the size we both reached last month if I were to guess."

An idle conversation took place, and something Emma told Annie made her realize something. Annie took her hand and stretched it upwards. Amazingly, she touched the ceiling.

"So, same time next month?" the colossal cat asked.

"You bet!" the big beautiful bunny replied. "But, do you know any bigger buildings we can compete in next time?"
