Shanoa's experiment gone wrong in a good way

(Hi guys, this is my first short story, I wanted to see, how you like it, and you might even have time to read it, since it's weekend and stuff... And if you do, then I will illustrate some part, and will write similar stories in the future :D)

Shanoa was looking at the screen anxiously. 

"I really hope this will help Betty..." she sighed. Lately, Betty had more and more problems with her uncontrollable lactation, and Shanoa was working faithfully on a serum that could put an end to it, or at least regulate it.

"Well... I guess it's... done?" she held up the little bottle looking at it's contents.

"I don't want her to feel like a lab-rat though..." she thought and looked around. 

"Where did I put that milk-producing drug...? Ahh, here it is." she took a bottle from a shelf and drank its contents.

"Ohh... is this what Betty feels each time she lactates?" she touched her tingling breasts and could feel her mammary glands swelling. She moaned a little, but remembered her objective, and went back to the bottle of serum she just created.

"Alright, here goes nothing..." She said as she drank the contents of the other bottle too, while her bras already got soaked with milk. She took off her clothes to see if there is any visible effect.

"Ahh...!" she moaned as she felt a surge of stimulation run through her body.

"It kicked in... pretty fast..." she panted. She then wiped off the milk from her tits, to see, if there is any more leaking out. But as she touched her nipples, a shock of stimulation flew through her body.

"Wha... Why are my nipples so sensitive...?" she moaned, losing her balance and falling on one of the shelves. As she trampled over the shelf, knocking off a bunch of bottles, most of which contained aphrosidiacs.

"Ohh no..." she said, but she didn't have time to pity the broken bottles, because she was more concerned with her swelling tits.

At first it wasn't noticeable, but by now she could clearly see that her boobs have doubled in size.

"Hello, Shanoa...?" Nicolas entered. "I've heard strange noises, is everything al-..." then he stopped, trying to convey what he was seeing.

"N-Nicolas!" gasped Shanoa, trying to hide her boobs with her hands, but as her hands touched her nipples, she scremed again from pleasure and let go of them immediately.

"Wh-what happe...?" Nicolas started to feel dizzy all of a sudden.

"Why am I...?" the aphrosidiac that Nicolas inhaled from the bottles Shanoa broke, started to take effect.

"I can't bear this tingling anymore...!" Shanoa moaned as she started to stroke her boobs and nipples.

She was constantly trying to hold back moans and screams and sprayed her milk all over her body. Nicolas was trying to hold his lust back, but then he saw something:

Shanoa, while playing with her nipples got them so swollen, that a visible gap formed in them.

Her fingers would occasionally run though her nipples stretching out the gap just a little, but this was enough for Nicolas to start fantasizing.

"Shanoa..." he said.

"Wh-what is it...? she asked, panting heavily.

"It's not fair, that only you can play with you nipples... I wanna too..." he said blushing a little.

"W-well I guess it is fine, since it's you..." she agreed hesitantly.

He threw his clothes away, taking a step towards Shanoa, who sat on a clinic bed in the meantime.

"Hurry, my nipples are tingling so bad..." she moaned.

"Well then, can I handle them with my dick?" he asked, looking at her swollen nipples, which were leaking non-stop.

"Do whatever you want..." she said, supporting her now melon sized boobs towards Nicolas.

"Well, if you don't mind, then I will try this..." Nicolas said, grabbing one of Shanoa's tits, with his other hand, pressing his dong agains Shanoa's nipple.

"Ni-Nicolas... What are you...?" Shanoa moaned, while throwing her head back from the intense pleasure.

"Your boobs are so big, and you nipples too, I'm sure my dick will fit..." he said, pressing his dick stronger.

"T-that's not possible, it's common anatomy, that...! Ahhh!" she couldn't finish, as she felt Nicolas' tip slowly stretching her nipples. "It... it should not be possible..."

"Spraying this much milk all over non-stop would also be against normal anatomy, but yours is clearly different..." commented Nicolas "Anyway, if it hurts, I'll stop, otherwise, there is no turning back..."

He felt Shanoa's nipple slowly stretching and stretching, letting his dick enter into her boobs more and more. Shanoa was constantly moaning, but she didn't try to stop him.

"You are so big...!" She gasped, as Nicolas got stuck a bit. But he didn't stop pushing, Shanoa's nipple slowly spread as big as his thickest part, letting him slide in slowly but steadily.

"It should be fine from now on..." he said "Now it just depends on wherher your boobs are big enough in volume."

He gave a final push, his dick slowly sliding all the way in, while his balls hit Shanoa's swollen boobs, as she moaned loudly.

"At least you shave properly..." Shanoa giggled, when she got her breath back. However, Nicolas couldn't reply to her because Betty came in right after it.

"What is happening here...?" She asked, a bit shocked at the sight. "Were you experimenting with some body modification serums again?" she guessed nervously.

"Not quite..." said Shanoa " It's just... a side effect..."

However Betty got hit by the aphrosidiac too, and started to loosen up, taking a few steps towards Shanoa.

"Th-this is..." Nicolas tried to explain, still having his dong fully inside Shanoa's boobs.

"...is hot..." Betty finished the sentence, pulling her shirt off.

"B-betty...?" Shanoa looked at her with confusion as her gigantic nipples bulged out of her shirt.

"You wouldn't let ME out of the fun now, would you?" she said, kneeling next to Nicolas, pressing her nipple against Shanoa's.

"N-no..." Shanoa gasped, while Betty already took the initiative and forced her nipple into Shanoa's.

"Come on, start moving!" she said to Nicolas who was still a bit dumbfounded, and stroked Shanoa's boobs, which he penetrated.

Nicolas started slowly pounding, looking at Shanoa's face it hurt for her, but apparently her face turned more and more into ectasy, which snapped him back into his previous mood too.

They quickly noticed the gurgling sound coming from Shanoa's boobs, as her plugged nipples had no space to let her milk flow out.

"Why are you lactating by the way, Shanoa?" asked Betty.

"It's... Ahh...! For an... Experiment..." Shanoa said moaning between each word, as Betty and Nicolas were humping her now rapidly expanding boobs.

"P-please pull out... I'm getting too big..." She moaned, while her boobs almost reached the size of yoga balls.

"Just... a little bit longer..." They said almost at the same time, humping Shanoa's gigantic tits.

They grabbed both of Shanoa's boobs, and as a final stretch, stroked it violently, before they ejaculated.  Betty's boobs bursted with milk, while Nicolas was trying to push his dick as deep as he could to release all of his cum inside.

"I'm cumming, I'm cumming, I'M CUMMING....! Shanoa moaned, while her nipples loosened up, bursting with milk, spraying her boobs' contents all over them.

She flopped on her back, panting heavily, while she noticed that the tingling sensation in her boobs is gone.

"We... gotta... do this... more often..." she panted, while she smiled in a satisfied manner. "But first, I'll have to create an actually helpful serum for Betty..." she added.
