Stephanie ambled into her hotel room, after having left the convention center, a frown on her face. The con is fun, she was texting to a friend, but I’m not sure my cosplay is up to par with most of the people here…

She tossed her phone aside and laid back on her bed, her slight curves moved gently back and forth. Stephanie rose up, and stood. “Time to take this off,” she mumbled, her previously-felt pride in her outfit lessening every time she thought about it. She began carefully pulling the pieces of her cosplay off, preserving them for tomorrow. Her phone buzzed somewhere; she’d pick it up later. Laying the costume on the desk in the hotel room, Stephanie pulled her pajamas on.

“At least there’s no wig to take off this time,” she mused. “Dyed pink hair coming in clutch. I hate wigs.” She grabbed her phone, finally, and read her friend’s response. Girl, your outfit is amazing. I wish I had time to come down to this con just for it. What problems are you having?

She sent a quick response. You know exactly what my problem is, Sola!! >:[

Stephanie curled up on the bed, clutching her phone tight in her hands. The response from Sola was almost immediate.

You were Lara Croft a few months ago and THAT ONE WAS GREAT TOO! Who cares if you’re not the EXACT physical proportions of the characters?!

Stephanie knew Sola was right. As much as she hated not being curvier, her cosplays should be judged more on their craftsmanship than how well she physically matched the character. She tossed her phone aside somewhere and set herself to falling asleep.

Stepping out into the convention center floor, Stephanie browsed a few booths before posing for a few pictures with fellow cosplayers. She was striding down the main pathway when her outfit was suddenly torn apart, her body bursting out of it. Stephanie was almost instantly looking down at herself, watching as her breasts eclipsed her feet. The tatters of her outfit fell away from her plumping form. Looking behind her, Stephanie discovered her lower half was plumping up too.

Growing rapidly, Stephanie was almost entirely nude, only a few remnants of her outfit still clinging to her body. Luckily, no one seemed to take notice of the quickly growing girl, despite the tremendous sizes she was reaching. Her boobs blocked Stephanie’s view of anything below them, her plump nipples reaching out past her toes, her breasts well past handfuls. As they approached her belly button, Stephanie let them drop from her hands and watched how they bounced. They were beyond the size of her head now, easily. She squeezed them, marveling at their size.

Suddenly, she heard some kind of rumbling, and her tits surged forward, growing down to her hips almost instantly. The sudden addition of weight pulled her down, and Stephanie was on her knees before the knew it, her boobs still plumping up bigger and bigger. Her butt was packing on mass as well, she could feel it, her butt and hips and thighs all growing together. She watched, stunned, and her breasts continued to happily grow. In moments, they touched the floor, her nipples now out of arm’s reach. She kept on growing and growing, seemingly picking up speed with every inch gained. Her vision was starting to be overwhelmed by boob, her bust blocking out everything in front of her. The weight of her butt was mounting, overwhelming her thighs, and she fell forward to rest on her huge, pillowy breasts. Stephanie’s boobs were past bean-bag chairs now, closer to small cars, taking up more and more of the convention center floor. Stephanie was sure everyone was staring at her, but no one did anything, even as she felt her thick nubs brush up against one of the booths across from her…

Stephanie woke up in bed, covered in a gloss of sweat. She breathed a sigh of relief. It was only a dream, she thought. Sunlight was streaming in through the window. Steph rolled over to check her phone and immediately stopped. Bringing an inquisitive hand up to her chest, there was no denying it. Her tits were bigger. Nowhere near her dream, but larger nonetheless. She pushed the covers off herself and sat up, feeling the weight of her boobs settle. Pulling her shirt up, Stephanie explored her new bustiness with her hands, feeling the weight and heft of them and discovering a new but not unwelcome sensitivity.

Finally finding her phone, Stephanie realized it was later than she expected, and past when she had planned on getting to the con today. She rose out of bed and stood to find another surprise, this time in the form of her butt wobbling from her steps. Twisting around, Stephanie’s face broke out into a grin as she sank a hand into her plump butt. In fact, everything down there seemed a little bigger, with wider hips and thick thigh below.

This figure was perfect for my cosplay. Who cares where it came from?

Stephanie regarded her cosplay lying on the table in front of her. This might need some finagling…

Letting things out where they could, Stephanie poured her new curves into the outfit that fit perfectly yesterday. Looking into the mirror, she figured there was no way she was fitting into it as well as before. Her cleavage bulged out of the neck of the outfit and her bum stretched her skirt obscenely; whereas yesterday it flowed down to her feet, it was now just below her knees. The stockings groaned around her thighs, trying their hardest to fit her plumped up frame.

“And now the only part of this costume I didn’t have to change,” she said as she grabbed her shoes. Pulling them onto her feet, Stephanie left her hotel room and meandered down to the convention floor, privately enjoying the turning heads around her. Steph was overcome with the feeling of déjà vu while walking around the center, visiting some of the booths she’d missed yesterday and taking pictures with other vocaloid cosplayers.

When Stephanie heard some rumbling, the source of her déjà vu became apparent. Her dream. She didn’t have time to react as her body began to grow again, her exaggerating curves beginning to overtax the confines of her clothing. Unlike the dream, people were noticing, pointing at her, staring. She needed to get out of here. Stitches were popping as Stephanie wobbled her way back towards the elevator, back to her room. Her cleavage was deepening, collecting the stares of the people she passed by. The hem of her skirt was rising up as her butt grew and grew, the waist of it beginning to split apart.

She frantically hit the button for the elevator as her curves pumped up. Stephanie’s shirt was being pushed down by her growing tits. Her areolas were starting to show over the top of her shirt, her fat nipples not far behind. The doors rolled open and she hustled inside, slamming on the “Door close” button. It was a pointless effort, no one was trying to follow her, but her sense of urgency demanded it. The metal box rose up through the building, back to Stephanie’s floor. Claustrophobia set in as she still grew as the elevator climbed; she thought it was mere seconds before her curves would hit the walls.

Thankfully, the doors opened before Stephanie filled the elevator. She stumbled through the door, feeling her hips brush the frame. She panicked as she could feel all her additional flesh jiggling as she walk-jogged to her room. Swinging the door open violently after scanning her keycard, Stephanie shut the door behind her and started tearing off her costume- what remained of it, at least. The waistband of her skirt split before she could take it off, and Stephanie’s huge butt was free, the basketball-sized cheeks wobbling as Steph struggled with the rest of her outfit.

The buttons and stitches at the front of her shirt finally gave up after doing their best, and the garment burst off Stephanie’s body, leaving just her arm bands and shoes still on. She twisted and turned, trying to observe the magnificent bulk of her curves, the hip-obscuring tits, the ass like twin beach balls, and the thighs that were quickly splitting her stockings. She bent over to try and pull her shoes off only for the weight of her boobs to pull her over onto them, the sheer mass of them keeping her from being able to put her hands on the ground.

Helpless, Stephanie laid on top of her boobs as they grew, her butt following suit still. The edges of her tits were growing closer to filling the space between the hotel bed and the dresser, just inches left until she was too wide for it. Stephanie’s nipples perked up as the skin of her breasts pressed into the cold faux-wood of the furniture, and just moments later, her hips pressed into the same items on the opposite end. She was being pushed up towards the ceiling, her tits growing under her, raising her up and up.

The weight from her butt pulled her down, leaving her almost on her feet as her boobs reached out further from her. Steph gasped as her butt pushed into the wall of her hotel room. She was quickly growing too big for the room. Her breasts grew larger and larger, growing closer to the door… as she finally stopped.

“Oh, god,” she whispered. “What the fuck am I going to do? Whatever did this… could you make me smaller? Like, a manageable size?” Nothing happened. “Come ooooon. Smallersmallersmaller. Please?” She scrunched her eyes closed and focused on the word smaller. A new feeling came over her and she opened her eyes again to see her boobs pulling back into her, shrinking smaller. “Oh, please, keep going, mama needs to be able to walk out of here. Smalleeeeeeeeeeeeerrrrr.”

She focused for a few minutes until her figure was back to the way it was this morning. Stephanie observed herself in a mirror, a little disappointed. “Well… I could be a little bigger.” Suddenly, her boobs pushed out bigger, eclipsing her rib cage. “Oh my,” she mumbled. “Am I… am I controlling this?” Deep inside herself, she focused again. Bigger. Stephanie watched as her boobs plumped, growing down her torso. Within moments, she was back to obscuring her whole torso with tit. She swiveled around. “Does my- yup, my butt grows too. Nice.”

“Now… do any of my clothes fit me right now?”
