“Come here, honey,” Grace called from the bedroom.
      Deserie dropped the plushies she was playing with — Charlotte the deer and Bluey — and came running as fast as her little legs could carry her. When her mommy called her like this, it usually meant one of a few things:
1. She needed help with something.
2. It was time for Deserie’s weekly injection.
3. They were about to have sex.
4. Some combination of the three.
      Deserie already had her injection this week, so that narrowed it down a little.
      “What’s up, Mommy?” Deserie asked.
      She spotted her mother sitting on the bed, holding a box. Deserie jumped up on the bed next to her.
      “I have a new toy for you,” Grace said.
      “Yay!” Deserie cheered, tail lifting in excitement. “What is it?”
      Grace opened the box, taking out a leather harness and some kind of bright purple object that looked a little bit like an eggplant. This didn’t look like any other toy Deserie had seen before.
      “This is a strap-on,” Grace explained. “It’s a kind of sex toy.”
      Deserie nodded. She knew the difference between sex toys and normal toys. Sex toys, like their vibrator, were special toys, just for her and Mommy to use, and could only be used in places where others couldn’t see. But, even knowing this, she still couldn’t figure out what the strap-on did. Strap it onto where? Strap it onto your head and pretend to be a unicorn?
      “But how do you play with it?” Deserie asked. 
      Grace giggled a little at her daughter’s innocence and gently rubbed the bulge in Deserie’s Bluey pajama shorts. “You know how you have a cock, and Mommy doesn’t? And how it feels really good for you to top me?”
      “Uh-huh.” One of the biggest differences between the two of them, aside from age and fur color, was the fact that Deserie had a cock and a pussy, while her mommy only had the latter. And one of Deserie’s favorite things to do was to be buried deep inside her mother.
      “Well, sometimes Mommy wants to have a turn topping, and this is a way for me to do that.”
      Deserie liked the sound of that. “Sounds good, Mommy— Wait, why didn’t you tell me about this before?!”
      She’d done all sorts of things with her mother before, but she didn’t know about the strap-on until just now. She felt like she’d been missing out!
      “You were just too little, honey,” Grace explained. “I was afraid I’d hurt you.”
      “But we like hurting each other,” Deserie said, thinking back to all the times they hit, scratched, and bit each other during sex.
      “When you were a little baby, you didn’t understand that yet. And besides, when you were that small, it wouldn’t have fit anyway.”
      “I guess that makes sense.” By that point, Deserie had stopped caring at the past. Right now, she only cared about the present.
      “Do you wanna take a look at it?”
      Deserie nodded and first picked up the harness. It reminded her of the kind she’d seen on people’s dogs, save for the leather part where the dildo was supposed to go. Then, she moved onto the dildo itself. The silicone texture was familiar to her, since she had toys and utensils made out of the same material. It was huge in her little paws: it was almost as long as her entire forearm!
      “Mommy, is it gonna fit?” she asked, looking up at Grace. She knew that her mommy was pretty stretchy inside — and therefore, so was she — but she still wasn’t sure if something this big could fit.
      “You might not be able to take the entire thing at first, but with enough practice, you’ll be able to,” Grace said.
      That made Deserie more turned on than she already was.
      “I wanna use it now, Mommy!” she said, getting on her back, just like her mother would when the tables were turned.
      “Okay, baby,” Grace replied. “Go ahead and take your stuff off, then.”
      “Oh, right!”
      In her eagerness, Deserie had forgotten she was wearing clothes at all. First, she slipped out of her shorts, leaving her in her diaper. She hastily undid the tabs and tossed it, along with her shorts, onto the floor. She was also wearing an oversized shirt, but didn’t take it off in hopes that it’d make things go quicker.
      Meanwhile, Grace was undressing, too. She, like her daughter, was wearing an oversized shirt and pajama shorts — they loved to coordinate outfits whenever possible. She tossed her shorts and panties onto the floor, and they fell in a pile near Deserie’s clothes.
      Deserie watched, fascinated, as Grace attached the dildo to the harness, and then adjusted the harness to fit her slender, hourglass frame. To the younger deercat, who didn’t really understand how all the straps on the harness worked, this looked like nothing short of magic.
      Grace crawled on top of her daughter and gave her a kiss as she slowly guided the dildo inside. Deserie whimpered and curled her toes. This was a lot different than Mommy’s tongue, or her fingers, but she definitely liked it.
      At first, Grace wasn’t sure if Deserie’s cries were of pleasure or discomfort. She soon realized they were the former, but even if they weren’t, she was much too turned on to stop. Grace lifted up her shirt, exposing her large breasts, and shoved her daughter’s face into them. The younger deercat gladly nuzzled into the soft warmth, paws digging into her mother’s back as Grace pushed the dildo further and further inside her. It got a little over halfway in before it wouldn’t budge anymore.
      “Mommy…” Deserie whimpered.
      “You’re doing such a good job, sweetie,” Grace purred, running a paw through her daughter’s soft, sandy brown hair.
      With that, she began to thrust her hips. Deserie let out a little squeak with each thrust Grace made, her cock bobbing uselessly between her legs, dripping onto the cream fur underneath.
      Grace pinched the first row of Deserie’s little pink nipples, making her moan and arch her back. Deserie had always been sensitive there, and by the time Mommy was onto the third and last row, she was squealing and writhing around in pleasure.
      “You love getting fucked like Mommy’s little bitch, don’t you?” Grace asked.
      Deserie nodded, unable to form words.
      Grace moved her paw even lower, to her daughter’s fully erect barbed cock. She’d been ignoring it for long enough. She stroked it with her first two fingers, starting at the bottom and working her way to the tip, as to not rub the barbs the wrong way. Deserie whimpered and bucked her hips in response.
      “Such a pathetic, useless little thing,” Grace sneered, continuing to get her daughter off.
      “Nuh-uh!” Deserie protested between pants. She’d just fucked her mommy the day before!
      “I should just lock it up when I’m not using it.”
      “No, Mommy!”
      “Why not? You haven’t been bad, have you?”
      Deserie shook her head. She only had a few rules she was expected to follow, and one of them was not to touch herself without permission. She hadn’t broken it — well, not recently — but, like most other kids, she enjoyed having freedom. Thankfully, her mother was just teasing. For now…
      Grace could tell by the way her daughter was twitching that Deserie was getting close. She thrusted harder, resulting in even more moans from the little girl. Deserie tensed up, and finally, she came, all over her tummy, and the strap, and the bedsheets.
      Grace gave her daughter a kiss as she pulled out. She took the strap off, and then cleaned Deserie’s body with her scratchy tongue. They’d clean up the rest of the mess later. She laid down next to her daughter and guided the little deercat’s head to her breast. Not only was nursing calming for the both of them, but it was a way for Deserie to recoup the energy she’d lost.
      Deserie eagerly snuggled up to her mommy and began to nurse, suckling as hard as she could in an attempt to get as much milk as possible.
      “Be gentle,” Grace told her, stroking her hair.
      Deserie tried her hardest to do as she was told.
      “Mommy?” Deserie asked, looking up at her mother with milk dribbling down her chin.
      “What’s up, baby?” Grace replied, wiping her daughter’s chin off.
      “Can we do it kitty style next time?” That was their term for doggy style, since Deserie deemed it “cuter.”
      “Whatever you want, honey.”
