A pear shaped, lovey dovey teacher swayed before you, having an orgasm almost every minute as the two of you played with her big booty. It's plushy giving way to firm texture captures your hands, jiggling with every movement. Every jiggle makes her moan more, her petite boobs rubbing into you.
"You like my booty?" She bounces but up and down, then slides her pussy along your pants. She's came so many times, the front of her track suit leaves a wet mark on your jeans. Her once loose pants are tight at the hip and loose everywhere else. She looked to be aiming to fix that.
A small pout as she begged, something she might've done so much because it was the only expression that made it obvious she wasn't glaring. "Make me as big as you like, as massive as you want. I can take it... cutie..."
The effort was there, but it didn't sound right coming from her mouth still. But between the pouting lips and blush, Ms. Janett- no, Cassie looked adorable. You didn't want adorable though, you wanted fuckable.
"Your butt will grow until it's the size of watermelons. However, it will all be fat from here on out." You stroke her butt, feeling the jiggling flesh pushing against you. "Your skin will be smooth, your body hairless, and your thighs proportional to your ass. So will your hips."
Her eyes roll back as you hear her growing and moaning, adding quickly: "And orgasms don't tire you out, or dehydrate you." If you didn't, Cassie might actually die of pleasure.
Her pants were glued to her ass, her panties visible and beginning to give out. That massive booty was being restrained by both panty and pants alike, and had taken the up and over approach. She developed butt cleavage, as the top of her pants stopped clinging to her waist and the cheeks peaked over the top. Her thighs were wet as her orgasms were now seemingly endless.
"Thank you..." She was now struggling to stand straight, her bum provoked at every second by the skin tight pants it had to break through. She almost seemed barely conscious, a sticky sweaty mess. She was drooling slightly, her cold image shattered by how lame she looked. "It's... too tight... but... it feels... so... good..."
She staggers off of you, turning to show off her new expanding assets. She falls into you, squealing quietly as her butt eats your lower half. "I want... you... enjoy... too..."
She began to clap her giant cheeks on you, speeding up the destruction of her pants. Seams snapped, flesh pushed, and with a snap, pants and panties alike were gone.
She was constantly cumming and howling with delight. She moved on pure instinct, any rational thoughts long gone. That whole 'pleasure from her ass' thing was a lot more significant then it first seemed.
Those massive cheeks slammed down on your waist and stomach, to big and erratic to properly aim. Her whole body twists and twitches, with her panting. Eventually, you give and cum, but she keeps going. Her massive ass sits atop you, grinding accidentally. She moves, giving herself pleasure. She gets pleasure, she orgasms. She orgasms, she twitches and moves.
"Do you... do you...like...?" Drool and tears cover her face as she leans back into you with the most innocent expression. "I wanna...be liked... I wanna... be big... You like big... You'll... like me more...right?"
Her glare is completely irrelevant in front of her own panting and soiled panties. Her clothes are sweaty and stick to her. Her butt is as big as your first hour teacher's. She rubs her head into your chest, practically purring and moaning, muttering "bigger... Bigger...!"
