The Spider - Part 6 (Patreon)

She was able to force herself to stay there for a while, until something thick and gooey began to ooze into the seat of her pants. She bit down on her thumb, closing her eyes as she used every ounce of strength to stop it, to clamp down... Thankfully, it worked, and, though there was still an obvious messy spot, for the most part, her diaper was clean.

She stared over at the door, then back at the closet. The effects of the webbing were wearing off... If she could get out, she could at least make it to the bathroom, if not all the way out of this house. She wasn't sure what she'd do if she did escape, who she could tell about this that wouldn't think she was insane, what kind of exterminator could handle gigantic spiders who just wanted their prey to behave like happy babies, but at least she'd be away...

Slowly, she crawled towards the door, trying not to make it too obvious what she was attempting. As another cramp hit her tummy, however, she realized she didn't have time for all that... With one final glimpse back at the closet, she shoved herself to her feet, dashing for the door, one hand reaching out desperately...

Just before she could grab the doorknob, a blast of sticky, pink webbing splashed across the door, covering the knob completely. A moment later, she felt something hairy on her feet, and a moment later she was yanked off of them, tugged backwards. Another lump of mush pushed out into her diaper as she felt the webbing being wrapped around her legs, and then her arms, panic overtaking her, keeping her from moving one of her hands up to her mouth, so, of course, the spider finished up with a pacifier.

With her backside in the air, and her knees held apart, there was little she could do to contain herself once the next cramp hit - besides, if she could have lasted much longer, the effects of the webbing that had leaked into her mouth would have started. In the end, she wasn't sure if she lost control completely, or gave in; either way, she wound up in an extremely messy diaper, again, as a reminder that the spider wanted her to stay on all fours.

Not that she had much of a choice... She was stuck like that for much longer this time, waiting for Cupcake to come home, so she had a feeling the effects would also last longer. Despite the humiliating position she was in, she was grateful to hear the front door open, feel the webbing start to loosen. When the door to the nursery opened, however, she was greeted by quite a surprise. Cupcake was there, of course, but so was someone else... 

"Hi, Mommy!" Cupcake chirped. "Isn't she cute?" The girl she was with nodded and chuckled. "This is a friend I made at school," Cupcake explained, while Mommy tried to find a way to hide her bulging diaper from this stranger, cheeks bright red. "She saw how you had me dressed yesterday, and asked me about it, and we started talking... She likes a lot of the same stuff as us, but she's way nicer! She said I could wear whatever I wanted to school, and bought me this pretty new dress, and... Oh!" She lifted her skirt, giggling. "She lets me wear real panties, not even those dumb trainers!"

Mommy's cheeks burned, realizing her little girl now had on something far more grown-up than her... Even as the other girl kissed her on the side of the head. "I'm proud of you for not needing anything more than this, but remember? We talked about this... You're supposed to keep your dress down, aren't you?"

"Sorry..." Cupcake looked down at her feet. 

"Sorry, Mommy," the girl corrected her. Cupcake looked up at her, then over at Mommy, confused. "She's obviously not a Mommy anymore," the girl said. "She's just your Baby Sis, remember?" Cupcake nodded, grinning. "How about you show me how well you can change her diaper while I get a nice afternoon snack made for the two of you?" Cupcake was all too happy to oblige. 

"You can't do this!" the former Mommy hissed as soon as the other girl had left. "That spider is going to get her, too... We have to get out of here!"

"Silly Baby," Cupcake giggled. "If you need Mommy to check your closet for monsters, I'm sure she'll understand..."

"But... You know it's real! It attacked you, it..." She paused, watching the amused looked on Cupcake's face. "Didn't it?" She shook her head... It had to have! That was the only reason she'd spent the day crawling around, and used all those diapers, and slept in a crib... She wouldn't have done that on her own... She'd seen it, she knew she had! But, the more she looked at Cupcake, the more she doubted, and the less she wanted to have this new girl open the closet. Sure, maybe the spider would attack, and find a new victim... Or, maybe, there would be nothing there, nothing to explain why she was now, indisputably, the Baby of the family....
