"What's all the yelling about?!"
Jen had never imagined she'd be pleased to see the dirty coveralls and scowling face of old Vince, the school's janitor.
"Can you turn down the dial please?" Jen called desperately. "One of the kids--"
"Those damn kids!! Always messing with school property!" Vince continued grumbling as he stalked over and adjusted Jen's backpack.
Jen felt the fluids pumping into her pussy slow down from a constant pressure to a pulse every now and then. She noticed as swollen and hot as her pussy had become, these irregular pulses were actually making her even hornier as each one surprised her. She blushed as the old man adjusted her hose, pulling it firmly to run between her legs and up her ass crack. He did something and Jen felt it snap into place on the pack.
"Thank you!" Jenny said. "I'm not sure what--oof!"
Jen gasped as the old man pulled her to her feet by her backpack straps. She strained to hold up the tray under her massive jugs. They were each easily two and a half feet across and full of milk sloshing from side to side as she shifted her balance. The slightest tilting threatened to have them jerk Jen off her feet. They looked more like a couple water balloons than a pair of breasts. Or, Jen had to admit, they looked like a pair of distended cow udders.
Vince got a hand under the tray to help her and slid his ubiquitous rolling trash can underneath. Jen leaned down and was able to use it to prop herself up. With the tray balanced on the rim of the can Jen could finally catch her breath. Stooped over that way she was acutely aware of both how massive her breasts had become and how exposed her ass was sticking out of what passed for her skirt with the hose slotted firmly up her ass crack.
"Don't you worry now," Vince said, "we'll get you back to the milker and you'll be fine in an hour or so."
Vince patted the top of her left tit, sending ripples across both giant jugs. Jen blushed furiously. Just this morning her body had been one of the most admired at school, even the other cheerleaders were envious of her large perky tits and long legs. Now it seemed even the janitor found her breasts no sexier than any other drinking fountain. Jen remembered the long line of kids and teachers squeezing milk out of her at lunch. Each dribble of milk passing her nipples had left her feeling contented and moaning with pleasure,but only a few of them seemed to get any pleasure out of their actions. Her pussy throbbed as another injection of hormones flooded into it.
Vince grabbed the front of the trash can and started off towards the kitchen. Jenny having no other options shuffled after him. She was appalled as she caught herself watching the old man's ass as he walked, but couldn't deny that as horny as she was she'd welcome even his attention. She felt her nipples tighten at the thought of being fucked and moaned involuntarily as droplets of milk ran down her breasts to puddle on the tray.
"Um, Vince? I was wondering, could you maybe, um..." Jen trailed off as the old man glanced back curiously at her, then down at her tits. He pulled an old rag out of his pocket and wiped the milk off her flushed flesh and the tray beneath.
"Leakin' eh?" He laughed. "Bound to happen as big as they've gotten. I'll stay to swap out the tanks, wouldn't do to come back Monday and find the floor covered with milk."
It finally dawned on Jennifer that when Vince spoke to her he didn't expect any kind of intelligent response. She'd heard him have similar 'conversations' with the change machine when it got jammed, and the drinking fountains when he worked on them. He was treating her the same way he did other school equipment.
"I'm still a human being! I have feelings and," Jen swallowed convulsively, "and needs, and right now I need you to fuck me." Jen felt her face burning with shame as she admitted how turned on she was.
