Kazz awakened in an unfamiliar place. She tried to move, but was restrained. Kazz was more or less upright, leaning back slightly so her view was angled somewhat towards the ceiling. She took in her surroundings. White walls, white floor, white ceiling. She looked down at her restraints and was unsurprised by the continuation of the sterile environment- she was tied to a steel table. What was more alarming was her current condition.

“Why the hell am I topless?” she shouted, her tiny nipples stiffening in the cold air of what she assumed was some kind of laboratory. She couldn’t see any doors in her position. “What’s going on in here? Anyone? Answer me!”

Kazz was answered by a voice on an overhead speaker. “Administering first dose,” it said, the voice steely and inhuman.

“First dose? What on earth?” Suddenly, a robotic arm popped out from under the table she was on. The arm ended in a needle full of blue liquid. “Don’t you dare put that in me!” she screamed, the needle closing in on her arm. It pierced her skin and injected the liquid into her. “Shit, I hope this doesn’t do anything… weird to me.”

Kazz didn’t notice anything different until she felt a pulsing in her chest. She glanced down, trying to discern if anything had changed. It didn’t seem like it had until her flat chest started to swell in time with the pulsing she felt, her breasts steadily growing larger.

“Are my tits growing..?” she asked as she observed them. Her suspicions were confirmed as her breasts happily plumped up to larger sizes, bulging out to grapefruit size quickly.

“Hell yeah, I always wanted big boobs. This is awesome!” Kazz’s boobs grew and grew, taking up more space on her torso with each passing second. As she watched them, she noticed her nipples were getting bigger too, staying in proportion with her breasts. They looked like eraser tips, remaining hard and stiff with her growth. Her tits kept swelling, growing closer to her navel as the seconds passed.

Kazz’s boobs began to resemble melons as the growth finally tapered. They reached the end of her rib cage, her nipples a few inches above her torso. “These boobs are a little bigger than my ideal, but it’s better than being flat,” she said, “Now if only I could get out of here…”

The robotic voice came on again. “Administering second dose.”

“Second dose? My tits are already too big!” Her eyes were locked on the needle arm as it approached her with the blue liquid again. “No no no please, don’t make me any bigger, these are already big enough! Any larger and I’m gonna be a freak!” It was no use. The needle pierced her skin again and the liquid flowed into her veins, beginning its work of enlarging her breasts.

“Nooo, not again,” she whimpered as she could feel her boobs start to grow again, her cantaloupe sized tits swelling into volleyballs, growing closer to passing her belly button. “Ugh, these are getting heavy,” she complained as the weight of her boobs started to pull on her. “Why are you making my tits grow? Is there anyone here?” Again, there was no response.

“They’re getting so… huge!” Kazz stared incredulously at her burgeoning tits, which were by now nine inches wide each, her penny-sized nipples starting to point outwards slightly. “Please, please stop growing,” she begged. Her boobs weren’t listening though, and they continued to grow into ever larger sizes.

By the time the bottoms of her breasts reached below her belly button, they were close to a foot wide, wider than her hips, wider than any tits Kazz had ever seen. “I’m just going to be a walking pair of boobs if this doesn’t stop soon,” she whined. However, she started to have a change of heart. Maybe having inhumanly large boobs won’t be the worst thing ever… if I can find shirts and bras to fit these behemoths. Either way though… my breasts do look… stunning. You’d think there would be some stretch marks from going from flat to basketballs in a few minutes, but my skin tone hasn’t changed at all. And those nipples… imagine what they’ll feel like getting sucked on… She shuddered from the thought. Hopefully they feel as good as they look.

As she had been coming to terms with them, Kazz’s boobs had surpassed her hips, and the growth finally stopped. A few inches past her hips and close to a foot and a half thick, her tits were otherworldly, rising up into the air to be capped by equally huge nipples. The nubs were like half-inch thick quarters now. Please no more growth, please no more growth, please no more- her thoughts were interrupted by the robotic voice.

“Test completed. Scanning.” A green light shone out of another arm from the table, which cascaded over her from head to toe. “Scanning complete. Dispensing.”

A tile in the floor moved down slightly and slid under an adjacent tile. From beneath, a rack of clothes rose up. “Dispensing complete. Releasing test subject.” The restraints on the table loosened and Kazz almost fell on her face from the sudden release, not to mention the huge amount of weight now added to her chest. Struggling to get her shoulders back up into the best posture she could manage, Kazz slowly walked over to the rack. She placed her hands underneath her breasts for support, sinking into the soft flesh. She received an electric feel from handling her breasts, a good sensation, something she had hoped for. I wonder… she thought, before moving her hands to her nipples and giving them a quick pinch.

Her knees buckled slightly from the intense feeling. “Oh geez… that is going to take some getting used to.” Not that I’m going to complain about it. Supporting her breasts again, she walked slowly over to the rack. “What have we got here? A shirt, maybe, so I can go out in public again?” She found two items here: a shirt and—even better—a bra. An absolutely huge bra. Kazz picked it up and looked for the size tag. “34P?!” She shouted. “I didn’t even know bras were made this enormous.” She slipped the bra and clasped the back to find it was a perfect fit and supported her breasts well enough to keep them from hanging below her hips.

“And how about the shirt?” It was a button up, and very obviously made for someone of her dimensions. Kazz put it on and did the buttons. I look pretty normal, she thought, Well, normal enough for a girl with basketballs on her chest. A door slid open in the room and she could see light streaming in from the far end. She walked through it to discover she was on Main Street in her hometown.

Well, at least I’m not in the middle of nowhere. She started walking back home, doing her best to ignore the stares she was getting from people on the street.
