Sudden Growth (Pinup)

"Whatever you do, don't press that button." Sally said, as Jennifer pressed the button.

"You idiot. Do you ever listen to anything I say?"

"I'm sorry, I just like buttons!" Jenny replied. She felt a tightness in her tank top.

"Well I hope you're ready to fill that thing out a lot more."

"Oh no, is this another muscle machine? I just got back to my normal size after I messed with your last one."

"No, this is something different. It's designed for mothers who are having trouble making and expressing milk."

"Oh... right. Does that mean-"

"Yup."

"So my-"

"Yup."

"And they're going to-"

"Yup."

"Okay so how long does it-" Jenny was cut off as her chest tightened and swelled, ripping open her tank top and leaving her with a set of massive mammaries.

"The issue is that it's way too effective. I can't figure out a way to program in the size or the amount of milk." Sally explained.

Jenny was only half listening. Her mind was distracted not only by the weight of her new chest, but also how sensitive they were. Each slight breath of air across her boobs felt like someone brushing a feather across them and her nipples were starting to get hard.

Something else stirred deep within her though. Sally's voice no longer registering, Jenny felt something from within her boobs. Like they were filling with something. In fact she could feel the remains of her tank top stretching again as the material became taut across her chest. Her nipples were already fully hard, but she could feel them getting bigger now as well.

"Hello, are you listening?!" Sally interjected.

"I... uh..." Jenny couldn't reply. All the sensations were becoming too much for her.

"Oh damn, are you getting bigger again?" Sally had concern on her face now.

"I think... I think something's... coming!" Jenny managed to get out.

"Oh shit, it's the milk! We need to get you to the bathroom before-"

Jenny's nipples exploded with milk. She cried out as a shower of white liquid sprayed from her nipples, coating the lab, the equipment and Sally with a sweet-smelling, warm liquid.

Jenny was dripping. Not only from her boobs, but also in her panties. She was almost shocked at how incredible it felt as the milk gushed from her breasts, each spray sending electricity all over her body, causing her to moan uncontrollably.

Eventually the milk started to slow down. She pushed her knees together, trying to squeeze that last little bit of electricity. She gasped. Jenny felt like she had just had 100 orgasms in a row. She opened her eyes to see the whole room covered in milk. Her milk. She was shocked at how much there was and how far it had gone.

Her eyes swiveled to Sally, who was sitting in-front of her, arms crossed.

"You are never visiting my lab ever again."
