Midnight turns Momo into a HuCow

"Today we are going to focus in on your lovely chest. I chose the biggest in class for a reason." Their teacher says from behind Momo as she reaches around and gropes the young woman's boobs. The touch and compliments make her smile and blush, feeling proud of her chest and no longer shy about displaying it to the class.

She lets go of her voluptuous orbs and opens a nearby mini fridge. "Now, are you all familiar with my company Midnight Milk?" She pulls out a bottle of milk with a stylish and sexy silhouette of Midnight herself. The class nods as most do know of the infamous brand. Only sold to adults as the milk isn't like normal dairy. Instead of coming from cows it's made with real human breast milk although how she gets so much milk volume remained a mystery. Midnight pops the top and offers the bottle to Momo.

"Yes, I've drank this before." Momo says as she takes the bottle and drinks from it, savouring the sweet and creamy taste. A few drops leak out and dribble down to her breasts as the bead of milk slides down her cleavage. Mina licks her lips at the sight, wanting to slurp up that droplet more than anything right now. She makes a refreshing sigh as she puts the bottle down. "Ah, delicious. Are you gonna teach us about lactation?"

"Exactly, and I'm going to let you all in on the secret to my company's success. The manager of the firm has a cowgirl quirk, a bit similar in body type to Pony but she has features of a cow and she truly has some udders on her. But the real key is her quirk's additional effect, her own breast milk enlarges the breasts of whoever drinks it and forces them to lactate for about 24 hours. My employees there drink it voluntarily to produce the product, becoming my HuCows. And that is what I brought here today." Midnight teaches the class as she pulls out a vial from the fridge, the liquid white with black spots just like a cow. "Momo, would you like to demonstrate the effects to the class? I even had a special modified version of your hero outfit prepared. You would remain at school for the next 24 hours to be milked by me and your fellow classmates." She says as she pulls the items out, a cowprint version of her Creati leotard that is white with red spots and a built in tail along with matching gloves, stockings, cowbell collar, and even fake cow ears. Alongside all that is the milking machine itself and plenty of empty bottles. Looking over all the gear only lights the fire in her bosom more, she doesn't care if she's seen or what this might due to her noble reputation anymore. Momo would become MooMoo.

She grabs the vial and drinks it with no hesitation, Midnight smiling broadly as she sees her student embrace the fantasy. Handing the vial back to Midnight, Momo's chest begins feeling warmer as a pressure begins to build and they see her mamaries slowly become more massive. Midnight knows this can take a while and begins dressing her student into the cow girl hero outfit. Slipping the stockings and hoof heels all the way up to her thick thighs, the gloves over her toned arms, the cute cow ear head band and slipping the leotard around her curvy body. Another modification is that the leotard does not cover but instead hugs around the base of her breasts as it would not be able to contain the now beach ball sized breasts and her large leaking nipples. Midnight and the class can't help but admire Moomoo as she is now, some taking their phones out to take pictures.

Momo is struggling to stand a bit, her new chest being quite hefty. Midnight sees this and offers her some assistance. "Mina, move her desk and yours so she can rest her udders on them. And do it fast or she won't be the only cow." Mina feels a shiver of desire run down her spine, very tempted by that offer but wanting to enjoy Momo like this first so she moves the desks under the HuCow's breasts so she can rest them. Momo thanks her before Mina returns to her chair.

Midnight grabs the milking machine "We've wasted enough milk. The milking device allow you to safely and pleasurably extract milk from a cow. It will suck the nipple in and form a vaccuum seal to ensure it won't spill." She explains as she inserts Moomoo's enlarged nipples into the transparent tubes, getting a murmur from the cow at the feeling. Midnight turns the machine on low for now and they see it begin to suckle the milk down the transparent tubes and start to fill an empty bottle.

"This feels amazing!" Moomoo moans, using her arms to apply more pressure on her breasts and squeeze more milk out. "I think you mean 'a_moo_zing' my pet."
