Laura moaned under her breath, “I wish… she’d give my fat cock an ass-job!”
"LAURA!" Ms. Mounds exclaimed over the softly beeping remote. "What are you doing sitting back there? That's not your assigned seat, now come up here and sit on my desk."
"O-oh, sorry," Laura blushed. She grabbed her bag with her lower set of arms and moved to the front of the class.
"Well?" Her teacher gestured to Laura's pants, which visibly had what seemed like a two-liter bottle of soda jammed in it, "How am I supposed to give your fat cock an ass-job if you're so intent on hiding it behind your jeans?"
Laura gulped as Ms. Mounds stroked the massive appendage through her pants. She hurriedly undid her pants and pulled them as her cock grew harder... longer... larger.
"A-ah," Laura moaned as the class giggled at her predicament. She was pulling her pants down, but her swelling cock kept pace, even past her knees. In a fit of frustration, she kicked off her pants entirely, freeing her fat, turgid dick. The member at its maximum possible size sprang up and smacked Laura in the chin, plastering her lower face with a baseball sized glob precum. Beautiful blue veins pulsed up and down the '(not-so) private thing', flush with vitality. She could hear whispers among her classmates, no doubt about her daily shameful display of cock.
"My-my, my dear pupil, as shameful as ever aren't we today?" Ms. Mounds cooed in tune with the remote. Laura's face turned beet red. "You seem bigger than usual; don't tell me you actually enjoy this? You're practically like a fountain of precum here, I feel like my ass needs to be twice as big to handle a growing girl like you."
And indeed, it was. Laura's cock towered over her head by a full foot. It took all four of her arms to stabilize, which was still difficult given her condition of leaking constant precum. Thick streams of sweet, translucent, lubricant dribbled down her cock, around her thighs, onto the desk, and then finally the floor.
"A-aaghg!" Laura moaned as Ms. Mound's warm, beachball sized ass-cheeks slid around Laura's log.
"Quiet down, now that you're in your proper seat, we will continue the lesson."
Ms. Mounds returned to the oral lesson, book and pointer in hands while simultaneously twerking off Laura's veiny cock. The rapid twerking of ass-meat casually flicking precum everywhere, and in an instant was covered in a two-inch thick layer of Laura's precum. Laura's cock twitched as she tried her best to pay attention, but in only a few minutes of getting twerked off she felt the rising tide of an orgasm. She felt burning hot semen travelling up her three-foot long schlong when she suddenly registered what Ms. Mounds had been saying to her.
"Oh no you don't, Missy! There's still fifteen minutes left of class, so you're not allowed to cum until then! The last time you covered me in your jizz, it took me four hours to wash out of my hair."
Laura shamefully wail-moaned in response, the beeping of the remote ignored, as she felt her cum recede back into her, her orgasm stopped at its very height. She felt all the hot semen gathering at the base of her cock, obediently waiting for the end of class a quarter hour away. She felt like she could die of shame as her hands gripped the desk until the knuckles were white.
Ms. Mounds continued twerking the bloated member, the slapping of flesh and splashing liquid regarded as completely normal. It felt like an eternity of pleasurable torment to Laura, but when she looked at the clock, only one minute had passed.
Lost in utter heat...
