Her

Again with this question. You don't know what it did the first time. Well, not the specifics. Your mum’s never done anything like this before, so it must have something to do with it. You’re not sure what else will change, so you decide to pick a different option this time.

As your cum gushes into her throat, she splutters. She pulls her lips off your cock, leaving streaks of saliva along the veins of your cock. She sits back a ways, her eyes taking on a dazed expression as the cum bubbles out of her mouth, dripping down her chin. You slump to the ground with her. Your muscles are fried from dishing out two loads in as many minutes.

It's here that you notice her shirt. This blouse, frilly and beige, is damp. At first you think it might just be splotches of cum, but the patches grow bigger. Mum begins to moan, reaching her arms under the hem of the blouse and ripping it off. With her skin now bare to you, you can see what’s happening. Her already massive breasts are bulging around her bras. The jiggling flesh is pushing through whatever holes it can manage. Looking back at her face, you can see she’s panicked. All this growth in such a tight space, it must be hard to breathe!

You spring into action as she topples forward onto her hands. Her voice is raspy.

“Off… Get off.”

You try to pull at the bras to loosen them a little, but she just gurgles in pain. Panicking, you run to the kitchen drawer. You pull out a knife, any knife you can. It’s big. Should be enough. You race back over, and she’s wheezing, struggling to take in air.

You put a hand on her back, to steady her as much as you can. Then, with all the care you can, you wedge the blade between the strap and her back, and pull away.

The bras explode forward, slamming into the floor, and your mum sucks in a long, drawn out breath. You collapse, not even realising that you had also been holding your breath. You let the knife slide away across the floor.

“Th-thank you.”

“It’s... Hpph... No problem,” You say.

It’s now you hear yelling.

“Hey David, where’s that- Oh my god!”

Ava rushes over to both of you, her own nudity forgotten as she grabs your face.

“Did you fall? What happened? Why is there a knife? Ms. Cappelli, are you okay?”

“Oh hello darling,” your mum offers a shaky smile to the panicked young woman, “I must’ve forgotten my milking today. I don’t know why I wore such tight bras...”

Hold on, did she say…

“Oh,” Ava replied, turning back to look at you, “Do you, uh, want me to leave while you finish up? How does it work?”

Finish up? What in the hell?

Your mum laughs, “Oh no that’s quite alright. But is there any reason why you’re naked dear? Or should I start taking a few guesses?”

Ava’s face flushed like an industrial toilet. She muttered some apologies, before bolting back up the stairs as fast as she could.

You propped yourself up on the tiles, and gave her a look. Now that she'd lost the shirt, you could see what she was talking about. Her tits were several cup sizes larger. Her nipples were standing at attention, and her areoles were even bigger than you’d imagined in your wildest fantasies. Each one was about the size of Ava’s palm, and they were puffy, as if someone had stuck helium balloons inside them. The most unexpected feature of all was the steady trickle of milk pouring from her nipples. You watched as it sloped down those pink areolas and dripped off the underside of her boobs like stalactites.

You didn’t know where to begin asking questions, but she was staring at you with a contented smile, so best to start somewhere.

Ava? Milk? Why did you do that?
