"Little one, we have a problem," Mommy announced, taking a bite of her spaghetti. "Do you know what it is?"
Little One shifted a little in her chair, looking down at her plate. She was hyper-aware of how her body felt, her bare breasts caressed by the air and her thighs sticking to the wooden chair. "I- I don't know," she said, fidgeting a bit.
"I think you do, baby," said Mommy. "What's the number one rule about your bottom?"
Little One blushed but answered, "It has to be ready for Mommy to fuck it anywhere, anytime."
"That's right, baby. But what happened today?"
Little One took a quick bite, feeling the shame wash over her. "I- I got too sore," she said. Unlike the teasing and blushing Mommy usually subjected her to, this didn't feel good. She had let Mommy down, and she hated it. The awful, distracting emptiness in her bottom reminded her, too -- she was usually plugged at all times for Mommy, but Mommy had said that if she was too sore to be fucked, obviously her hole needed a break from her pluggies, too. She had protested -- it wasn't the same to be plugged -- but Mommy had insisted. She hated having an empty bottom, too.
"That's right, sweetie. You got too sore, and Mommy couldn't get off by fucking your hole, could she?"
Little One shook her head. "N-no, Mommy," she said. "I had to use my mouth when you wanted my hole."
"Now, I know it's been hard for you ever since we increased the size of your daily pluggies a few days ago," Mommy went on. "So I think what you really need is some more training."
"More training?" Little One asked, taking another bite.
"Mmhmm," said Mommy, smiling. "Obviously, your hole needs to get used to being fucked for longer periods of time, and your pluggies just aren't cutting it anymore. But Mommy doesn't have time to personally attend to the level of training your hole obviously needs, so I've bought just the thing."
"What do you mean, Mommy?"
"I've ordered you a fuck machine, little one," said Mommy. "It should be here the day after tomorrow. Once it arrives, we'll pick a time for you to have a daily practice fuck."
Little One's eyes widened and she gave a squeak of surprise, but didn't protest.
Once dinner was finished and Little one had cleared the dishes away, Mommy called her over again.
"Yes, Mommy?" Little One stood in front of Mommy, hands clasped together and eyes on the ground.
"Turn around, baby. I want to make sure your hole is nice and healthy and ready for your nighttime plug. I kept you empty for dinner as a punishment, as you know, but if your hole really does need some recovery time, I'll have to keep it empty a bit longer, okay?"
Little One nodded and turned around, bending over and holding her knees. She didn't like being empty, but at the same time, she felt warmth spread over her body. Mommy would take care of her and keep her safe.
She felt one of Mommy's lubed up fingers gently massaging her ring, then felt it slip inside her bottom, probing gently.
"How does that feel, baby?"
"G-good," she said. "Not full enough, though."
She heard Mommy giggle, then add another finger. "Is that better?"
"Oh, yes," she sighed, relaxing a bit.
"Okay, baby, I don't see any problems," Mommy said. "I'll put your regular pluggie in for bed." And so saying, she withdrew her fingers and reached for the plug on the nightstand beside her. She quickly lubed it up and eased it into Little One's hole, letting it slip a little further in with each push of the plug, then withdrawing, until finally it seated itself and let her hole close up around the neck of the plug.
"Thank you, Mommy," Little One said dutifully, straightening up. She wiggled her hips a little, adjusting to the sensation.
Mommy led her to bed, snuggling in beside her. "How does your hole feel, baby?"
"Oh, it's so much better! I was really afraid I'd have to be empty," Little One said, nestling in. "My bottom just doesn't feel right when it's empty anymore... But now I can feel it inside me, making me all nice and full. It feels even bigger than it did last night. I know that's just because I was empty for a while today, but I still I love when Mommy makes me take a nice big pluggie up my bottom."
"And how is your breeding hole, baby?"
"Oh, it's been dripping since you put my pluggie back in, and even more now we're talking about it," she said, squirming a little bit. "And my clittie is all big and hard, just like Mommy likes it."
"Good," Mommy said, kissing the top of her head, then turning out the light. "Goodnight, baby."
"Goodnight, Mommy."

Two days later, they were both staring down at the newly assembled fuck machine and the fairly intimidating dildo that went with it.
Little One shifted nervously, looking over at Mommy.
