Kat's brother invites her to explore some ruins that will change her life forever

This choice: Wears her shirt despite how much it stimulates her nipples  •  Go Back...
Chapter #4

A Tight Squeeze

    by: Komfy Kat Author IconMail Icon
Kat took a deep breath, the breeze flowing lazily through her hair as it waved gently over her shoulder. The rustling of the leaves grew louder as the wind picked up, overcoming the sound of the nearby waterfall. Finally, she nodded and reached down to grab her wet shirt from its place by the stream.

Slowly, Kat pulled the shirt over her head, wincing as the fabric teased at her enlarged nipples. Her breath caught in her throat as a wave of pleasure coursed through her at the shirt's caress. The shirt felt strange like it had shrunk slightly, though she knew it hadn't. Perhaps she hadn't imagined her breasts swelling ever so slightly.

With a nod, she followed Nathan towards the far end of the clearing, her shirt teasing her nipples with every step. They'd been walking for about an hour when Kat first noticed it. Her chest felt like it had some weight to it. Every step she took, she could feel the new resistance in her breasts as they took a millisecond longer to follow the rest of her torso, bouncing slightly out of rhythm to her step. It was a new and strange feeling. One she'd hoped to experience, but now... now she was trying to ignore it.

With every step, her breasts felt ever so slightly heavier. The bounce was somewhat more noticeable. Her shirt was tighter. There was no doubt in her mind that her breasts were growing the more the shirt stimulated her nipples. Still, she tried not to think about it and just ignored the sensations as she trudged along, following Nathan as he led the way.

Her shirt was just slightly tight now, but it felt ever so slightly more snug as the sun dipped towards the horizon. Her breasts were beginning to noticeably tent the fabric, growing like two small mounds out of her chest. She grimaced, knowing that by the time they got back to the Jeep, there would be almost no chance of hiding the change from anyone who knew her. Every step took her farther away from being able to hide the differences. And she was only going to get bigger. Now, it was apparent to her that Helona's gift would be a curse. At least, if it kept growing at the current rate.

Kat had never had to even consider wearing a bra before, yet at the rate, her breasts were growing, there was no doubt in her mind that she'd definitely need one by the time she got home. Already, her chest had swollen from flat to at least an A-cup. Kat shuddered as she imagined how big she'd be at the rate she was going. Kat had grown a full cup size in less than 12 hours, and if she didn't take steps to reduce the stimulation on her nipples, she might be immobile within a month. Finally, Nathan came to a stop, looking back over his shoulder at his companion as she caught up, "I think we're close to where we parked the Jeep. How are you holding up?"

Kat took a deep breath, glancing down at her chest before responding, "Fine, I guess. I... I think I'm starting to get used to the constant stimulation from my shirt, but... well, the sooner we get home, the better."

Nathan nodded and turned to continue walking. He spoke quietly, and Kat wasn't sure if she was supposed to hear or not, "Hopefully, I can find some way to reverse this. There has to be something about this in my research..."

Kat took another breath and turned her gaze towards the sky. Stars began appearing in the darkening sky, occasionally blocked by a stray cloud as it made its way lazily through the heavens. Her breath caught in her throat as the moon appeared through a gap in the thick canopy of leaves. It shone brightly, its white light shining on her face as if it were attempting to comfort the cursed teen. The chirping of crickets somewhere in the night soon filled the silence between the two siblings as Kat lowered her gaze to watch Nathan striding into the black of the forest around her. His movements were silent save for the occasional cracking of a twig or rustle of leaves as he moved through the woods.

Kat exhaled slowly as the faint shine of the stars began to twinkle above her head. Despite everything, she let a small smile creep across her face as she tried to find some beauty in the situation. Wasn't this precisely what Kat had wished for? Hadn't she asked Helona for breasts more significant than her own? Hadn't Helona granted her wish? Kat took a deep breath and watched the trees sway slightly over her head. The pleasure coursing through her body hadn't lessened in the least. Yet, she was beginning to get used to the constant euphoria attempting to overcome her senses.

Kat took a few wobbly steps after her brother, her new breasts bouncing with each step she took after him. It was such a strange sensation, almost like a weight pulling at her chest. They didn't exactly hurt, but they certainly had more mass than when she'd left the temple. Every step seemed to make them slightly heavier than the last, the bounce becoming more pronounced and their weight more noticeable in the fabric of her shirt.

By her estimates, they probably had at least another half hour of hiking ahead of them. That was another half hour of stimulation and growth before she could rest and try to figure out what to do with this new curse she'd been given. Though part of her was tempted to give in and stimulate them more. Part of her desperately wanted to push the bounds of what her body could handle and just go for broke and really enjoy what Helona had given her. An opportunity to have the most enormous boobs in the world...

Still, there was another part of her that was terrified of the prospect. What would her life be like as her chest expanded? How would she handle everyone staring at her as her chest grew and grew? Who would take care of her when she could no longer do so herself? Nathan? She didn't think her brother would be thrilled to have a giant-chested sister draped off him, no matter how attractive she was. Kat let out another breath, her breasts expanding ever so slightly in the fabric of her shirt.

As she walked, Kat could see the outline of her massive nipples stretching the fabric of her shirt in the bright light from the moon. They were probably four times larger than they'd been that morning when the two siblings had left their parent's house and growing larger with every step she took. She'd say they were out of place on her petite body, save for the fact that her chest had swollen with them.

Finally, they found the Jeep, parked in the bare dirt clearing a short distance from the forest edge. Nathan turned towards Kat, and his eyes went wide as they fell on her chest. Kat smiled and held up a hand in mock defense, "What? Do I have something on my shirt?"

Nathan shook his head and took a deep breath, "I guess I'm just used to seeing you with a much flatter chest. You... you definitely look a lot more... feminine."

"What's that supposed to mean?"

Kat stared her brother down, putting hands to hips and puffing out her chest in indignation. Yet, despite her tough stance, her eyes flared for a moment as she felt her shirt strain a bit further against her chest as the mounds seemed to grow in response to her movements.

"I mean... um... that... um... before, you looked more like a boy. Now, you're definitely a girl."

Kat's eyes narrowed slightly, "Oh?"

"Y-Yea... I mean... you look much softer now. Sh.. you're more feminine... and... and... you have bigger breasts... that's all..."

Nathan quickly turned away and got in the Jeep, leaving Kat standing alone in the clearing as she turned her attention to her own chest. The heaviness of her new breasts pulled against her shoulders, and the shirt teased at her nipples with every breath she took. Every breath added ever so slightly to the swelling of her chest thanks to Helona's curse.

Kat took a deep breath and wrung her hands as she tried to steady herself on a pair of legs that suddenly felt as if they were made of Jello. Her chest was real. She was really growing. She wasn't going to wake up... suddenly... with everything back to normal. She would look like a girl for the first time in her life. And this was the new normal for her.

Kat let out a sigh as she slumped into the seat of the Jeep. Nathan had been a little bit more supportive after a minute, but she could see the concern on his face as he looked at her chest. She was really going to have to get used to this new body of hers, and fast.

The two of them were silent the whole trip home. Kat left the shirt on, despite the constant teasing of the fabric against her overly sensitive nipples and the growth she knew it was causing. So it was that, or ride topless next to her brother.

As they pulled into their driveway, Nathan turned to Kat, "Get some sleep and try to avoid stimulating them any more than necessary. Wear some baggy clothes to school tomorrow. Maybe no one will notice your chest. Then, I'll head to my lab and see if there's anything we can do to stop the curse. You'll be back to normal in no time."

"Thanks, Nathan. I'll... I'll take it easy."

With that, Nathan gave Kat a brief hug before she exited, and Nathan drove off to his lab. With a final look at the sky, Kat made her way inside. Her parents were already asleep, and she carefully made her way towards her room. Her mind was racing with possibilities. She could take Nathan's advice and try to avoid any excessive growth. Or she could just give in and let it happen.

She sat on her bed and turned her attention to her chest. She could feel how much larger they were. How much more obvious they would be as she walked down the street or went to school. It was exactly what she wanted, but now that it was happening, she felt cold and scared inside.
