As Missy sat on her bed, furiously humping her giant stuffed bear while wearing a wet and messy diaper, she listened to her Mommy fuck her new girlfriend in the guest room. Missy couldn't help but wonder how she had gotten here. How had she become so pathetic? As she continued to rub herself to her Mommy's porn star moans, Missy could feel the eyes of her hundreds of stuffed animals staring at her and judging her.
Life hadn't always been this way for Missy. When Mommy and Missy first moved in together, their roles in their relationship were well-defined. Missy was a precocious adult-toddler who couldn't be trusted to keep her pants dry or stay out of trouble, but was always around to help satiate Mommy's needs for 'big-girl cuddles.'
Mommy, on the other hand, was a dutiful caregiver, always there to take care of Missy's every need. Those needs includes diaper changes, baths, feedings, and of course helping Missy with her need for more than occasional 'big girl' releases.
Beyond the age play dynamics, Missy remembered her relationship with Mommy being quite normal for the first six months they lived together. Yes, Mommy would change Missy's wet diapers before Mommy railed her with her strap-on. Sure, Missy found herself humping wet and messy padding as she ate Mommy out. But, although their sex was pretty kinky, it was still frequent, mostly normal, and, from Missy's perspective, excellent.
Even most non-sexual aspects of their relationship were normal. Just six months ago, Missy and Mommy shared a room and a bed. They slept together every night and woke up together every morning. They weren't the AB/DL couple who converted their guest room to a nursery for the little partner to sleep in every night. They were closer than that.
All of that changed about two months ago. Mommy had to fly out of state for work for a month to supervise the start-up of a new manufacturing plant. She was scheduled to be gone for a month. The whole situation was horrible to Missy. How was she supposed to survive without Mommy for a whole month?
Mommy, the dutiful caregiver she was, did what she could to minimize Missy's distress about the separation. She special ordered a giant teddy bear for Missy to sleep with at night while she was gone. The large stuffie filled half of their bed by itself and alternated between saying, "I love you, baby," and, "You're a good girl," when Missy squeezed the bear's left paw. Mommy even went so far as to douse the stuffed bear, quickly dubbed Mommy Bear, in her perfume, so that it would even smell like the dominant woman.
Once Mommy left, Mommy Bear became a huge comfort for Missy. Every night, Missy would find herself cuddling into the giant stuffie's chest, inhaling Mommy's scent as she repeatedly squeezed the bear's paw to bask in the sound of Mommy's loving words.
After Mommy left, it didn't take long for Missy to start to look to fulfill her big girl needs on her own as well. Just a couple days after Mommy left for work, in the wee hours of the morning, Missy found herself with her hand in her wet diaper, desperately trying to cum. However, without Mommy there, it just didn't seem right. Missy threw her free hand to the side, and accidentally pressed Mommy Bear's paw. The stuffie, in Mommy's voice, said, as it had a hundred times before, "You're a good girl." Those words sent a thrill of pleasure through the diapered and desperate woman that she hadn't felt since Mommy left. That gave Missy an idea.
Tentatively, Missy climbed on to Mommy Bear, mounting the stuffed animal with one leg on each side. She grabbed Mommy Bear's left paw in one hand and buried her face into Mommy Bear's chest. The smell of Mommy's perfume was intoxicating.
Slowly at first, and then increasingly furiously, Missy began to thrust her hips into Mommy Bear's padded body. As she humped, Missy squeezed the bear's hand, activating the revised messages.
"I love you, baby. You're a good girl," Mommy's voice said over and over again.
Missy started to moan into Mommy Bear's chest. The warm, wet padding of her diaper stimulating her throbbing pussy. She continued to breath deeply through her nose, sucking in as much of Mommy's scent as she could. With Mommy's voice ringing in her ears and smell feeling her nose, Missy could almost imagine that she wasn't molesting a stuffed animal, but was fucking her partner instead.
In a matter of a few minutes, Missy reached her limit. Her toes curled and her eyes rolled back in her head as she came. She then let her body relax and collapsed onto Mommy Bear's soft padding. She popped her thumb into her mouth just before saying, "Fank you, Mommy," and falling asleep.
Missy's experiments with Mommy Bear didn't end that night or end with Mommy Bear. With her partner gone, Missy had no adult supervision, and she took full advantage of it. During the day, Missy found herself waddling her padded bottom through all of the toy stores in town, buying every stuffed animal that called out to her. At night, Missy took care of her adult needs in the most childish way she could. Nightly, she found herself rubbing her wet and messy diapers onto all of her new 'friends' until she fell asleep in a post-orgasm haze.
By the time Missy's Mommy came home, the master bedroom they shared had been completely altered.
"Missy! Mommy's home!" Mommy said as she walked through the door of the master bedroom for the first time in a month. Her jaw dropped open at what she witnessed.
Missy was on the bed, her hair a wreck, obviously unbrushed in days. Missy's pink diaper was full to bursting with pee, and a suspicious smell in the room told Mommy it was full in another way as well. Drool was dripping down Missy's chin, making it as wet as her diapered pussy, as she mindless humped a giant, stuffed pink unicorn.
The unicorn wasn't the only new stuffed animal in the room. The king bed that Missy and Mommy shared was now completely covered with stuffed animals. Similarly, stuffed dogs, cats, bears, and every other sort of animal stared out from every corner of the room. Mommy started to glower as she realized that Missy had turned their once adult bedroom into a toddler's playroom.
"Missy! What is going on here?" Mommy said sternly as she took in the room. Missy looked up and froze. Mommy looked so incredibly beautiful that Missy wanted to jump off Juniper, her noble unicorn stead, immediately and give her a hug. However, the stern look and anger burning under Mommy's eyes stifled that desire.
"Um... uh... Nuthin' Mommy! I was just, uh, playing! Welcome home!" Missy stuttered out.
"I knew I should have never left you alone! I was only gone a month! Look at this place! You've turned my bedroom into a nursery!" Missy's Mommy ranted as she walked into their bedroom. "Where am I even supposed to sleep? It looks like you replaced me with a toy store!"
Missy had to admit that Mommy had a point. Their bed was so full of stuffed animals that Missy herself had taken more to curling into it like it was a nest, rather than laying in it like a bed. There definitely was not room for another adult to lay on the bed.
"I... uh... I... well..." Missy couldn't come up with an answer. Interrupted mid-hump, Missy was not prepared to justify just how far she has delved into her little side while Mommy was out of town.
Watching her pathetic, diapered girlfriend fail to find words as she confronted her, Mommy's look and overall demeanor softened. "Oh, princess, don't worry. This wasn't your fault. I should have known that a baby-brained, little pamper packer like you couldn't take care of herself for a whole month," Mommy said as she walked over and kissed Missy on the forehead. "We'll talk more about this later, but for now, it looks like I interrupted your play time. Why don't you show me how you play with your new toys?"
Missy practically melted at the positive attention Mommy was giving her. With Mommy actually in the room with her, she was ready to do anything to get the other woman's approval. So, as instructed, and with renewed vigor, Missy began to continue thrust her hips into her trusty stead Juniper.
If only Missy had known them what she knew now. The show Missy put on with Juniper for Mommy was the first of many. Having come home to her room being functionally converted into a giant nursery, Mommy decided it was in everyone's best interest if she moved out of the master and into the guest room, letting Missy have the little room of her dreams.
Mommy's move also meant that Missy and Mommy weren't sleeping together anymore. And, much to Missy's chagrin, not sleeping together had more than one meaning. After coming home to find just how little self control Missy had unsupervised, Mommy let Missy know that she didn't feel comfortable having 'adult time' with such a little girl anymore. Mommy let Missy know that for the foreseeable future, if Missy wanted to stay in any sort of relationship with Mommy, Missy would only be allowed to make cummies by humping her stuffed animals, just like she had for the month while Mommy was gone.
When Mommy moved to the guest room, she also let Missy know that she was going to start seeing other people. Mommy had big girl needs that needed to be fulfilled too, and, unlike Missy, Mommy wasn't going to get off by humping teddy bears. Plus, Mommy had explained to Missy, Missy clearly needed more adult supervision. Maybe Mommy could find a partner who'd be willing to be Missy's second Mommy?
And that's how Missy found herself here, humping Mommy Bear while her real Mommy fucked another woman in the next room. As Mommy's screams came to a crescendo, Missy closed her eyes and buried her face in Mommy Bear's chest. She squeezed Mommy Bear's paw, letting Mommy's recorded voice merge with her real life scream. Missy hated that this was as close as she would ever get to fucking Mommy again. She hated that some other woman was getting to enjoy the body that should be hers. But, what she hated the most was that she did this to herself, and, even worse, deep inside, she enjoyed this.
Missy pressed Mommy Bear's paw again.
"I love you, baby," Mommy's voice rang out for the thousandth time.
Missy let her frustration, anger, humiliation, and horniness wash over her. She let herself cum while humping her stuffed animal, knowing, deep inside, this was the only way she'd ever get off again.
