Demonic Possession and Diapers!? Part 6 (Patreon)

Back at home, Jackie stood in her bathroom. Caitlynn had been kind enough to give her a ride home after the downtown shopping trip and after parting ways with her friend she shuffled upstairs to the bathroom, glad to see that her mom wasn’t yet home.

She made it inside and released the diaper's tapes, allowing it to plop heavily to the floor before cleaning herself with a pack of disposable wipes. On the floor next to her the massively soaked padding had been placed into a garbage bag. She'd rolled it up and discarded it with glee.

Once she got the diaper off she stood still, uncertain of how to proceed. On the counter next to her was the black paper bag that contained her new book full of occult magic, a clear bottle of viscous fluid… and the plug.

All three made her thoroughly nervous given what she'd recently experienced, but the plug was the scariest to her by far. Having never experienced putting anything up her ass before Jackie worried the bulbous monster she’d bought may not even fit.

“Maybe I was too impulsive…” she said to herself, pulling the rubber sex toy from the bag, “It’s not like I’ve even had an accident like that.”

For all Jackie knew her troubles could be over already. Nothing strange had occurred the entire drive home and when the shop owner didn’t detect anything she felt a wave of relief spread over her, especially after what had happened downtown.

However standing directly behind her the demoness that had made it her personal business to torture Jack screamed and shook, infuriated by the girl’s purchases. “How dare she!” she hollered, “Does this insolent little fool think that meager sex toys and a cheap recreation of a third-rate spellbook will stop me? She only delays the inevitable.”

Because of the laws of the paranatural, the horned demoness's ability to affect the physical world had dwindled steadily over the course of the day. Forcing Jackie to wet herself took an incredible amount of energy, which paired with the possession of her friend the infernal being had little left in the way of power to stop her plaything.

All she could do was rage in her extradimensional space while Jackie slowly dribbled viscous lube onto the peaked end of the rubber plug, preparing herself mentally for its insertion. Anything more would force her to spend several days recovering enough power to wake back up

Nervously Jackie lowered the slimy rubber monster to her bottom, pushing it between her cheeks until it met her rosebud. She inhaled quickly at the feeling of the sudden cold but pressed on–literally.

Her hand slowly worked the tip back and forth, prodding at her back door and doing little half twists to work the bulk of the plug in slowly. Thanks to the numbing nature of the lube it wasn’t a painful experience for Jackie but it was… weird.

At its widest point she struggled with it, feeling her body could open no wider to accept the toy. Just as she had thought, the plug was too big for an untrained ass and no amount of slow pushing would work the beast inside.

“I’m in too deep to go back now,” she said in between deep breaths. With her free hand she grabbed the lube bottle and reached back, spurting a generous amount between her buttcheeks and the plug.

The demoness, not expecting to enjoy the show of humiliation quite as much as she was, stopped her temper tantrum. It was clear to her as she watched that Jackie would have no chance at getting the plug into herself, not without a little “assistance”.

“It’d take everything in me,” she said, resting her chin in her hand as she contemplated, “I’d be forced to dematerialize for a few days. It might be worth it to teach this little brat what her attempts to fight back get her.

While she considered Jackie seemed to be doing the same. The brunette stood absolutely still, almost like she was frozen with the widest point of the plug cresting through her asshole. The demoness laughed to herself, feeling silly for her previous rage. She should have known that she could turn this situation around. It was just a longer route than she originally planned for.

The demoness kissed her finger, leaving a bit of infernal fire to grace the tip. She could feel her legs disappearing as she did so, her power becoming too weak to maintain a corporeal form even in her own extradimensional space. Her essence was returning to the rattle where she’d be able to feed off of Jackie’s desperation and reconstitute herself, but before she went she reached forward, placing her cursed fingertip on the flared back of the buttplug.

“I may be gone for a few days, but this will make sure you don’t forget me cutie pie.”

Jackie could have sworn she could hear something behind her, like a slow sensual whispering. Looking into the mirror, she caught a glimpse of a pair of deep red lips twisting into a smile. Then it was like something pushed on the slick plug, popping it in her suddenly. This act elicited a loud yelp from Jackie, who wasn’t expecting the sudden change in pressure as her hole was spread wider than she thought possible before it devoured the plug down to the stem connecting the round head to the flared base.

The pressure pushing against her inner walls was overwhelming and caused Jackie’s knees to buckle slightly as she adjusted to the sensation. “I-It might have just been better to risk shitting myself.” she said, panting heavily. It got even worse when just as she felt herself getting used to it it was like it was getting warmer inside of her, something she couldn’t explain or understand.

Giving it a nervous tug, Jackie found herself instantly regretting her decision when she felt it expand both outside and within as her hand graced the flared base. The stem holding the rubber toy inside of her stretched her once again, becoming almost as wide as the round portion’s full diameter before it had started getting bigger.

Her hand flew away from the base, fearing that was what was causing the rubber's sudden growth. Still, the feeling of her bowels being pushed wide by its bulk didn't stop immediately, continuing for a few seconds after she took her hands away. “Oh no,” Jackie moaned, realizing the shopkeeper was wrong. Whatever was haunting her was obviously still nearby and had cursed her again, this time using her own solution to a problem that hadn’t even come up yet. “Maybe I was too impulsive...” she groaned.
