Spanking Mary's heroine kids
 

It was midnight in the UA dorms. Inside Momo's room, a six year old girl with long white hair, sparkling red eyes, a horn, a pink nightdress and pink socks was having fun with her babysitter, the hero student Momo Yaoyorozu. Her name was Eri, and currently, the two were now talking about a certain legend Momo had heard of...

Memo a tall busty teenager witu long black and red pajamasswas looking after cute little Eri who asked about a legend which made her smile for a good laugh. 'Well you see there is a ghost in a mirror we're if you moon at it and say "spanking Mary there times. She will come."

The little cutie blinked, adorably confused "Mooning...like, if we opened the window for the moon to shine in? And her name is...Spanking Mary?" Eri asked the taller teenager in red pajamas, as she looked quite cute in her own pink night dress "Why? Does she get spanked a whole lot?" She said, the long-haired white child giggling at the idea of that "Poor Mary than..."

She giggled at this cuteness." No a mooning so where you bare your bottom at someone and I heard spanking Mary us called that because she spanks others."

"Bare my bottom...at someone?" Eri said, shyly looking over her shoulder at her dress-covered butt with a blush, before looking back at Momo "Wait...she does? Is she...mean or nice...? I've never heard of her before..." Eri said, the little girl now seeming to be much more interested in Spanking Mary.

"Well I heard that she is strict but nice. Maybe you like to meet her." She said. "All you have to do is moon at the mirrior."

Eri blushed, as she smiled, shyly nodding "Ummm...sure, I guess...can you join me than? It'd be embarrassing for it to just be me mooning her alone..." She asked Momo quietly, blushing cutely and giving Momo puppy dog eyes.

She giggled at this " sure, Sweety" she said before holding her hand and leasing her to the mirror.

Eri smiled, happily following Momo to the mirrors "Thanks..." Once they got there, Eri stepped forward a bit, looking up at Momo with a wide-eyed, curious look "So...I show the mirror my bare butt...and than say Spanking Mary, right?" She asked innocently.

"That's right." She said holding a giggle as this will funny to see her moon.

Eri stepped forward, shyly turning around and bending over, blushing as she lifted her pink night dress, revealing her light blue granny panties with UA symbols, and than pulled those down, the cutie mooning the mirror with her large, pale butt cheeks "Ummm...spanking Mary, Spanking Mary, Spanking Mary?" She chanted a bit hesitantly, blushing cutely and looking at Momo in embarrassment "I don't think it worked..."

Momo chuckled at this see Eri shake that cute chubby bum at the mirrior. "Here I will do it with you." She than pulling down her red pajamas pants and undies showing her larger round bare bottom. "Spanking Mary, spanking Mary, spanking mary."

Eri blushed, giggling a bit as she gave her chubby bare butt a shake towards the mirror, making it wobble and jiggle quite a bit as she giggled. Watching Momo also moon the mirror, the little cutie smiled shyly, blushing as her sitter's large and round butt was shown bare as well "Thanks Yaomomo-san for helping..." She said, giggling a bit more now at the sight of the teen's big bare cheeks...and too distracted to see what was forming in the mirror.

"You are welcome. And by the way fool you." She chuckled giving Eri a light slap on the rear not know that someone is coming inside the mirrior.

"Eeeep!" Eri squealed, grabbing her fatty butt with both hands, the adorable white-haired girl looking up at Momo with a cute pout "Awwww, but Momo, that wasn't very nice!" She said, rubbing her chubby butt cutely with both hands, only looking even more adorable and spankable to Momo...and possibly somebody else as well.

"Come on its not that hard." She chuckled before look in shock at a woman with red hair in the mirror with a stern face on them.

"But it surprised me..." Eri said, only to see her sitter looking in shock at the mirror, making her decide to look too...and gasped, her big red eyes staring in surprise and awe to see a woman with long red hair and a stern frown "Wait...that's her! That's Spanking Mary! She's real!" She said "We're actually gonna meet her..." She said with a cute, embarrassed smile, still having her chubby butt bared.

Than the two felt someone grab them from before and the two were now facing the floor over the lap of Mary now sitting on the bed.

"Eeeep!" Eri squealed in surprise, the little girl now suddenly finding herself laying over somebody's lap next to Momo, her round bare butt in full view as the cutie saw the bed "Wait, what's going on?" She said, her eyes widening as Eri started to panic a bit.

"What's going on?!" Momo as she next to Eri over the lap like child making her kick for she is pinned.

"You two have been naughty." Mary scolded as she raise her hand.

"Huh? What do you mean, Miss...Mary? What did we do?" Eri asked, a bit scared now as she laid next to Momo, pinned as well.

Eri than felt a loud slap onto the bare bum of the white haired hair making it jiggle with a pink handmark.

"Eeeeeeekkk!" She squealed loudly, her chubby bare bottom bouncing and wobbling quite a bit with the loud smack "Owwwwiee, that hurts!" She whined out cutely, a pink handprint on her pale cheeks.

Sge thanks move her hand onto Memo larger bottom hitting hard in the centre with the cheek wobbling and also a pink handmark.

"Owww! Let us go, please! We didn't do anything!" Momo squealed out, her rounder and fattier butt wobbling quite a bit thanks to the loud smack.

"You have." She said sternly as she work each cheek for a good smack.

Both of the girls over her lap squealed, their fatty cheeks bouncing over her lap "Ouch! Eeek! But...you're not real..." Momo yelped out, as Eri was whining and squealing "Owwwiiee! Ouchies! Please Mary! We'll be good, honest!" The little cutie said, unused to be spanked so hard.

"I am real and now tell me you sins." She said as she start to slacker harder once both bums are pink.

"Owww! Owwwiieee! Ahhhieee! I...I broke the law and rules once to help Midoriya and Todoroki save Bakugo!" She confessed, yelping and squeaking loudly at the harder spanks to her large, round butt "Ngyeeek! Miss Mary, please! Ouchhh! At least not so hard on Eri! She's never been spanked before!"

"Ahhhiieee! Ooowwweiiiee! Eeeekkk! I...I once took some things home from here when I shouldn't have! Owwww!" Eri squealed out, starting to tear up and squeal out adorably, as her chubby, pinkened butt was spanked harder "Agghh! Eeeeeee! Oww oww oww! Kyaaaaahhhh!"

"And were you ever spanked before?" She asked.

Momo slowly nodded "Yes, I was..." She said, sniffling a bit.

"When?" She asked as the bug cheeks start to go red from that powerful swattong hand.

"Owwww! Eeeekkk! When I...owwwiiieeee...came back from that mission...ooowwwwiiiee...!" Momo cried out, the older teen starting to sob a bit, while Eri was starting to cry adorably, their fatty cheeks starting to turn red "Waaaahh...Mary, please...I'll be good, honest!" The white-haired cuties said as she cried at the hard spanks.

After two more smacks on each cheeks she than pick them both up for a hug.

Both girls hugged her back, bawling into her shoulders with their big, bright red butts on display behind them, looking quite like two naughty little cuties that had been disciplined properly "We're sorry...Mary..." Momo said between sobs, as Eri nodded, nuzzling into her more "Yes..." She said, both of them looking quite cute to the stern woman

"It's OK. Yiu are forgiven." She gently as she sing a sing that will put them both to sleep.

They both smiled a bit at that "Thanks..." They both said, the babysitter and child soon falling asleep in her arms peacefully.

Soon the two with woke only in a bug bed together but Memo reaize that her body I'd smack with both she and Eri are now wearing a onesie with dripseat on the back with their bottoms now bigger and fatter than normal

Eri yawned cutely, getting up and noticing she was wearing a cute red onesie "Huh...?" She asked, as these were not her normal pajama clothes. Than she turned to see a small girl that looked like...."Yaomomo-san? Is that you?" The white-haired little girl asked in shock, her red eyes widening cutely.

"Yes why?" She said in a small cute like Eri. "What with the change of clothes?"
