Frisk and Chara’s harem! (Private!)

[ABDL MHA]

(I would prefer it if you start this one)

[Shadejr8]

(Frisk is a nearly flat chested girl in this one being a slow developer.) "Chara what do we do?"

[ABDL MHA]

“I don’t know I’m bored Frisk”

[Shadejr8]

"Why not travel the various alternate universes at random?"

[ABDL MHA]

“Sure, sounds like fun!” Chara said, sounding excited.

[Shadejr8]

"Great." *she opens a portal and walks through it*

[ABDL MHA]

*Chara walks through with Frisk* “Where have you taken us?”

[Shadejr8]

"I don't know." After walking around for a bit Chara would see a much more mature looking frisk getting undressed

[ABDL MHA]

Chara was surprised and looked away with a blushing face before trying to warn frisk not to go around the corner.

[Shadejr8]

Frisk asks why before seeing and covering Chara's eyes with her hands

[ABDL MHA]

He was surprised and tried to get her off “Frisk get off-“

[Shadejr8]

"No! Your not allowed to look unless you promise to only look at this me's body and not that bimbo."

[ABDL MHA]

“Fine I’ll only look at you whatever makes you happy. She looks a bit like you though.”

[Shadejr8]

"She techincally is me if I wasn't a late bloomer and slow developer in the breast and height region." *she removes her hands as she removes her shirt and training bra

[ABDL MHA]

Chara blushed wondering what she was doing as he tried to stop himself from looking round the corner not wanting to get spotted “What AU even is this?”

[Shadejr8]

"I thinks its an au where everyone is female or all the females have large chests and are very motherly."

[ABDL MHA]

“Okay well what do we do?” Chara said, trying to be very quiet...

[Shadejr8]

"We could look around or just go to the next random universe."

[ABDL MHA]

“Okay maybe we could take a look around!” He said beginning to walk with her.

[Shadejr8]

They would see a person wearing a mettaton t-shirt and overhear that mtt is doing a live concert right now

[ABDL MHA]

“Do you want to go and see it?” He asked, looking at her.

[Shadejr8]

She nods and says let's go

[ABDL MHA]

He followed her and was trying to hide from the other monsters with him

[Shadejr8]

They would see various monsters in diapers with mtt's face on them

[ABDL MHA]

He would be surprised holding onto Frisk as they walked around

[Shadejr8]

A monster offers to tape mtt brand diapers around the two humans waists

[ABDL MHA]

“We don’t wear diapers we’re fine thank you-“ Chara says trying to pull Frisk away as well.

[Shadejr8]

Mtt would appear wearing diapers too

[ABDL MHA]

Chara would hide behind Frisk looking up at the tall figure “Frisk what do we do-“ He whispered.

[Shadejr8]

"Talk to her Chara she won't hurt you."

[ABDL MHA]

“Maybe we should just wait until the concert.” He said looking up at her still.

[Shadejr8]

"Chara don't be a baby."

[ABDL MHA]

“I’m not a baby!” He said sounding annoyed remembering the diapers they got offered.

[Shadejr8]

He imagines how cute Frisk would be in them

[ABDL MHA]

He would blush a light red before looking at her waiting for her to speak.

[Shadejr8]

"Darlings why aren't you cuties in my mtt brand diapers?"

[ABDL MHA]

He just said “uh we decided to use the bathroom-“ he said not really knowing what to say. He saw how puffy they were and were pretty sure he might not be able to walk with it on

[Shadejr8]

"Oh that simply won't come with Mama Mtt dears."

[ABDL MHA]

He would try to pull away from her grip-

[Shadejr8]

She would give him a warning spank to do what she wants

[ABDL MHA]

He would just follow her looking over at Frisk. “What is she gonna do-“ he whispered.

[Shadejr8]

Frisk whispers probably diaper us

[ABDL MHA]

“We can use the bathroom though and I don’t think I’ll be able to walk in them they’re so thick-“

[Shadejr8]

She whispers just go with it

[ABDL MHA]

“Okay.” He said continuing to follow her.

[Shadejr8]

She leads them to her resort as she instructs them to strip and lay down

[ABDL MHA]

Chara would strip quite quickly and lay on one of the two tables they had been instructed to lay on.

[Shadejr8]

Mtt rubs his cock as she tries to get him erect

[ABDL MHA]

He would be surprised and would look over at Frisk as he became erect.

[Shadejr8]

Mtt would ask if he wants a blowjob or a boobjob

[ABDL MHA]

“Boob job-“ He said as he looked up at her thinking about how wrong Frisk was

[Shadejr8]

She wraps her soft warm breasts around his erect cock and starts moving them up and down along his shaft

[ABDL MHA]

Chara would be surprised and would moan slightly whilst watching her go,

[Shadejr8]

She licks his cock and begins sucking it while giving him a boobjob

[ABDL MHA]

He would come to close to cumming as he moaned.

[Shadejr8]

Mtt would pull off and lock a chastity cage around his cock before quickly diapering him with an enchanted diaper that won't come off until its been thoroughly used

[ABDL MHA]

Chara would look like an actual crying baby with the diaper on as he squirmed and shivered whilst crying.

[Shadejr8]

Mtt overrides his mind to make him think of himself as a horny sissy baby that has to contantly hump his diapers to get off

[ABDL MHA]

Chara would squirm trying to fight it whilst looking over at Frisk to see if she was okay.

[Shadejr8]

Hew would be unable to fight it as the program overrides his mind

[ABDL MHA]

He would lay there unresponsive for a moment before beginning to not like the boyish clothes he was wearing.

[Shadejr8]

(Bbl. Gotta charge my phone."

[ABDL MHA]

Okay...............//

[Shadejr8]

Mtt: So darling how do you feel?

[ABDL MHA]

I feel weird mama!!!!

[Shadejr8]

"What is your gender? Are you a boy or a girl?"

[ABDL MHA]

He began to think for a moment unsure.

[Shadejr8]

She waits for her to figure it out

[ABDL MHA]

“A girl...” He says even though his body is a boys body.

[Shadejr8]

"Good girl. Now mama Mtt is gonna set you down and you can go play and hump your sister."

[ABDL MHA]

“Okay.” He said still sitting on the changing table where he got his mind reset.

[Shadejr8]

Mtt picks him up and sets him back on the ground

[ABDL MHA]

He would sit there and would look around looking for Frisk to see what had happened to her.

[Shadejr8]

She isn't changed aside from being older and diapered

[ABDL MHA]

Chara would crawl up to her curious of what she would do.

[Shadejr8]

She asks what hapoened to him

[ABDL MHA]

He looked up at her confused as he began to hump one of the toys they had been given.

[Shadejr8]

She shakes him trying to snap him out of it

[ABDL MHA]

He would begin to try and snap out of it but couldn’t resist humping the toy.

[Shadejr8]

She takes the toy away

[ABDL MHA]

He would sit there holding his head trying to break out of what she had done.7

[Shadejr8]

He is able to break out of the baby programming but not the sissification programming

[ABDL MHA]

“Frisk?” He asked whilst trying to break the sissification trying to use whatever power he had to do so.

[Shadejr8]

"Yes Chara what is it?"

[ABDL MHA]

“Alright I think I’ve broken out of all it.” He would go and remove the cage but keep the diaper on. “Shall we go to a different AU and maybe get these diapers off?”

[Shadejr8]

The cage magically reappears as his diaper tapes disappear as Frisk says yes let's go

[ABDL MHA]

He would be surprised and would use his little hate to take it off not wanting to be caged. He would follow her not able to take the diaper off.

[Shadejr8]

The cage reappears again it seems it can't be removed

[ABDL MHA]

He removes it again and jumps through the new portal so that AUs magic won’t work on him anymore.

[Shadejr8]

It fails as items from another au usually carry over into the next

[ABDL MHA]

He would use all his magic to remove it forever as he asked Frisk “What AU is this?”

(Not really into caging sorry, I like bondage and pet play and am open to anything else.)

[Shadejr8]

She shrugs and says I don't know

[ABDL MHA]

“Come on surely you know where you took us and this diaper isn’t coming off-“

[Shadejr8]

"I don't know okay! Sans didn't teach me the part about how to open portals to specific universes."

[ABDL MHA]

“Alright sorry-“ He says just following her and looking for any monsters or humans.

[Shadejr8]

They would find noone nearby

[ABDL MHA]

“Maybe this a genocide-“ He said keeping close to Frisk looking around.

[Shadejr8]

"That's definitely possible."

[ABDL MHA]

He would look for any signs of dust or anyone.

[Shadejr8]

It seems this au is just empty maybe its an in progress au

[ABDL MHA]

“Oh well what should we do?” He asked, looking around still for any versions of them or monsters.

[Shadejr8]

They would find a single monster

[ABDL MHA]

Chara would peek to see who it was and what they were wearing.

[Shadejr8]

They were naked and it appears to be an older monster kid

[ABDL MHA]

Chara quickly looked away “Seems this AU is in development you can pick this time if you can figure out how to.”

[Shadejr8]

"I already told you I can't."

[ABDL MHA]

“Just send us somewhere random then.I’m just curious.”

[Shadejr8]

She does so as they end up in a underlust underswap combo universe

[ABDL MHA]

He would get up from the golden flowers and would look around.

[Shadejr8]

The flowers aren't golden instead they are a light purple

[ABDL MHA]

He was surprised “This is different-“ He said to Frisk.
