AUTHOR'S NOTE: EVERYONE INVOLVED IN THIS STORY IS AGED 18 OR OLDER.
It had been a few months since the event at the farm. The boys had largely lost interest by now, though she still got the occasional pinch on her butt, always eliciting a long moo from her. It made her blush fiercely, but the boys seemed to like it, and Ellie didn't want to be a killjoy.
She walked into school after the Easter holidays excited for a new term. She wore her usual uniform, a short skirt that fell just below her tight butt, and a shirt with one button done up and the bottom tied in a knot under her cute titties. This wasn't the normal uniform code, but the teachers had given Ellie her own special uniform to follow. Some of the girls got mad at her for it but it wasn't her choice! She said hi to a few of her male friends as she walked into form. They were always so nervous that they never made eye contact with her, staring at her chest instead, Ellie found it very cute. Ellie went into form, a special classroom for repeats and starting chatting with her friends.
Suddenly she felt a hand grab her ass cheek under her skirt and squeeze it.
"Mooooooo," She said, unable to stop herself.
"Hey Milky," The perpetrator said, "your tits are looking great today."
Ellie turned around, it was Brad, also on the football team. He'd also been there at the farm.
"Thank you, Brad," She smiled. The first few times people had complimented her tits and ass she'd said that it sounded a bit inappropriate, but after a teacher had spanked her for being "ungrateful for compliments" she'd learned to be less vain and take the praise with a smile.
"Here," He pulled a bottle with what looked like a milkshake out of his bag, "I made this for you, you should drink it."
"Oh, it's ok," Ellie thanked him, "I'm not that thirsty."
"That's fine," Brad said, "You can drink it throughout the day."
"But I've already got my water bottle."
"Yeah, but this drink is much nicer. It even looks a bit like cum," He said shaking the white, milky liquid, "You can pretend you're sucking a cock, like back on the farm."
"Brad that's so inna-" As Ellie opened her to mouth to gasp her disapproval Brad pushed the bottle in between her lips. He cradled his other hand behind her head to stop her pulling away and began squeezing the contents of the bottle into her mouth. With no other option, Ellie started gulping it down, it was a good thing she didn't have a gag reflex. Ellie hadn't realise how much Brad wanted her to try this drink!
"Good girl," He murmured, stroking her hair as Ellie swallowed squeeze after squeeze of the liquid. It tasted like a thick cream, but sweeter, with a more interesting flavour to it.
"I'll see you tomorrow Milky," Brad smiled after she'd emptied the bottle and gave her tit a quick squeeze of before walking away.
Ellie blushed as she led out a high pitched "moo".
"You shouldn't let the boys do that to you, Ellie, you don't need to be so submissive all the time," One of her friends told her disapprovingly.
"No, it's my own fault for dressing like this," Ellie excused the boys, "We can't expect them to keep their hormones in check so easily."
The next few days followed similarly, Brad approached her each morning and fed her the milkshake he'd made her. She didn't argue after the first day, as she didn't want to be rude. She'd noticed that she preferred the taste every time she tried it. One day, Ellie woke up to realise that her tits had grown. Quite significantly too. They were at least a full cup size bigger, and felt very heavy, almost denser. Ellie tried on a few bras, but her big tits made it so that none fit anymore. Hoping she wouldn't get in trouble, she decided to forgo a bra all together, tying her biggest white shirt under her large naked tits. When she walked into form she started anxiously looking around for Brad. Over the past few days she'd actually started craving the morning milkshake. Brad came in a few minutes later.
"Hey Milky," he said sitting next to her, "Your tits look massive today."
"Thank you," She beamed, "Do you have my drink?" She asked anxiously.
"Of course I do, but unfortunately I was out of bottles, and had to put it in something a little different, so you might not want it anymore."
Ellie wasn't sure what could be bad enough to warrant that, she really wanted her milkshake.
Brad reached into his bag and pulled out a large dildo out of his bag, it was 14 inches long and incredibly girthy, with veins all of it. At the tip there was a hole.
"It was the only thing I had that could hold all the liquid Milky sorry." He told her.
"You didn't have anything else?" She asked, surprised at Brad's suggestion.
"Like I said, nothing that fit the whole milkshake," He said apologetically.
"Um, ok then," She agreed. It didn't seem to occur to her that Brad could have put the liquid in two smaller bottles.
He handed her the dildo.
"Wait Brad," She said giving him puppy dog eyes, "Could you feed it to me please? It's just so big."
"Of course I can Milky," He smiled.
He held her head and pushed the dildo in and out of her mouth, sliding it right down her throat. The class watched as Ellie deepthroated the sex toy right in front of them. Most of the class just sniggered and turned away, having become used to Ellie's frequent, inadvertent slutty displays. Ellie sucked and licked at the dildo until every last drop was drained.
"Thank you Brad," She smiled, creamy milkshake dripping out of the corner of her mouth.
Her first period was history. She sat the same seat in most of her lessons, the one directly in front of the teacher's desk. As the lesson progressed, she felt her tits grow heavier and heavier. Near the end of the lesson one of the girls sitting next to her, Mary, leaned over and whispered to her.
"Omg Ellie I didn't know you were pregnant."
Ellie turned to her, surprised.
"What do you mean?" She asked her classmate.
"Your tits are like way bigger, and you're leaking."
Ellie looked down in surprise to see wet patches on her white shirt, exposing her big nipples.
"Oh my gosh!" Ellie gasped, "What do I do?"
"You need to pump," Mary urged, "Remember what happened to Melissa!"
"What happened to Melissa?" Ellie asked.
"Didn't you hear? She got pregnant and Principle Tillett expelled
].. He said that teenage pregnancy looks bad."
When Ellie got home she quickly did a pregnancy test. It was negative. This made sense. Ellie took birth control and frequently had to buy plan B to deal with all the cum that somehow ended up in her pussy. That didn't explain her leaky nipples though. She tried to think of what had changed in her schedule recently that could cause it but nothing came to mind. All of the thinking had made her tired, so she decided to just go to bed, and wait and see what tomorrow brought.
The next day her tits were even bigger. It took effort just to sit up, they were bigger than watermelons, and felt even heavier. Her areolas alone were the size of her boobs the week before. Not even her school shirts fit her now, bra or no bra. She put lots of nipple tape over her boobs to stop the leaking and covered up with a big winter coat. On the way to school she stopped by a charity shop and bought a white XXXL men's shirt, though the transaction was not as smooth as she'd hoped. In her hurry to get out the door she'd forgotten her purse and phone, so had no way to pay.
"Please sir," She begged, "I'll pay right after school."
