Ashley Redecorates.

As the end of summer neared Ashley's anxiety grew, knowing that even if she didn't give up her identity she would have to adjust her personality in order to be taken seriously at college. To balance this out, she decided to lean harder into the pet lifestyle at home. She kept her accessories on constantly, and she even started wearing the plug tail she'd left in the back of the closet since she bought it.

Today, she sent you and Tibby out for groceries while she stayed behind to rearrange the apartment. Despite your and Tibby's badgering she refused to tell you what she has planned, dismissing you with a "You'll see when it's ready. I'm not kicking you out for the rest of the day, I only need an hour."

It feels weird to go out as a duo, but with the start of college around the corner it's not a bad idea to practice being apart. Not that you've been together constantly since Ashley moved in, she visits her doctor for regular checkups (the latest of which revealed that she may not be as sterile as other pets, which is why you wear condoms when you have sex with her). But you and Tibby usually spend that time cuddling at home and preparing a nice meal for Ashley's return, not going out. You comfort yourself with the knowledge that she's not being excluded from some big activity. You're just going shopping.

Which is not to say you don't have fun on the way, that's impossible when Tibby is involved. You joke around in every store and you regale your pet with stories of your life before you adopted her, stories Ashley already knows because she was there when they happened. Tibby still finds it hard to believe that you've seen Ashley in a bikini dozens of times and even in her underwear but never felt the urge to ask her out, and ribs you about being so oblivious.

With a trunk full of groceries you prepare to drive home when Tibby spots a costume store, and of course you have to check that out. Unlike the stores that cater exclusively to pets, this one carries items more suitable for cosplay or halloween.

You entertain yourselves by trying on different things and sneaking up on each other, and you make sure to send Ashley pictures of your best picks to get her opinion. Her favorite is a couple's costume you create by mixing and matching parts of different collections: Tibby's own accessories along with a chain-mail bikini and parts of a witch costume turn her into a sexy feline sorceress, while a combination of small devil horns, some carefully applied makeup, and Tibby's leash around your neck makes you her shirtless incubus thrall.

But you can tell the shopkeep is getting annoyed with your antics, so you put everything you tried on back where it belongs and head to the register. You leave the store with a pair of goggles and a labcoat from a biopunk collection. The goggles are made of bronze and covered in small rivets, with curved green lenses. The coat is a traditional white labcoat, but tinged green near the bottom with a faint pattern of bubbles rising from the hem. The back is split to accomodate a tail, but it's subtle enough that it wouldn't look weird without one either.

When you get back to the apartment Ashley welcomes you both home with a hug and a kiss, and the moment you've put your bags down she leads you to the living room to show off what she's done in your absense. The couch has been moved closer to the far corner of the room, and is standing a foot or two away from the wall. Several bedsheets are stretched between it, a wall fixture, and a cabinet to roughly resemble a squat tent. An open flap in the front lets you peek inside, where the floor is covered in thick blankets and pillows.

You spot Ashley's gameboy on one of the cushions, but before you can get a closer look she's grabbed your arm and started rapidly talking. "I built a warren! It's a place I can curl up and get away from things when I want some solitude. Not that I want to get away from you! It's just to destress if college gets too much for me or something, I want you to cuddle with me in there sometimes! I'm rambling!"

You let her keep talking as you walk over to peek behind the couch. The space behind it is packed with cushions to create a sort of tunnel, a side exit to Ashley's tent warren thing. "Well, it doesn't take much space out of the room. If it helps you cope I'm happy," you tell her. "We got something for you while we were out, by the way."

"Really? What?"

Tibby rushes back to the front door and comes back holding the labcoat and goggles in her hands. "Tada! Why wait dozens of years or however long it takes to study when you can put on the coat right now and show us how sexy you'd look as a pet scientist? But you have to act like one too, it's the rules!"

"Very well," Ashley proclaims with a big smile as accepts the labcoat and throws it over her current outfit: a tight pair of jeans, a graphic t-shirt with an image of Bugs and Lola Bunny (who are considered offensive caricatures in this world, but it's ok because she's a bunny too), a pair of black socks, and of course her ears and tail. Then she turns to you. "You shall be my test subject, and you my research assistant. You will disrobe the subject so we may commence testing."

Tibby shrugs at you with a "She's the boss."

You play along and let yourself be stripped by Tibby. She places a hand on your hardening member before turning back to Ashley. "What now?"

"Escort the subject to the preparation room." She gestures for Tibby to come with her. A tug on your cock compells you to follow the girls into the bathroom, where Ashley picks up her toothbrush and squeezes a large dollop of toothpaste onto it.

She gives you an evil grin and explains the experiment. "Remember how this stuff affected us? Today we're going to find out whether males are susceptible to the same effect."

Then she sticks her toothbrush into her mouth and starts scrubbing. Tibby quickly prepares her own brush and follows suit. Once they've worked up a good lather, both girls spit into the sink and crouch in front of you. They start slow by sticking out their tongues and licking each side of your shaft, but then they get closer and start kissing it as well. The sight of your pets acting like they're trying to french kiss with your cock in the way is a huge turn-on. The cold tingling of their saliva adds an exotic element too, but it's not as intense as you expected after Ashley's reaction. It's most powerful near the sensitive skin of your glans, and can barely even be felt at the base of your cock.

Frustrated by how well you're taking it, Ashley steps it up a notch and wraps her lips around you to give you a wet blowjob. Within seconds you're screaming, but not for joy. Ashley's spit burns like fire in your urethra.

She pulls off you and stares at you in shock, but Tibby seems to know what to do. Standing up, she pushes you into the shower and steps in after you, not bothering to take off any of her clothes. After ripping the shower head off the wall, she crouches down again and aims the stream at your cock. The cold water makes the pain even worse, but as it gets warmer a soothing sensation overcomes you. Tibby thoroughly cleans your crotch, not stopping when your moans of pain turn into moans of relief. She continues using her hand and the warm water on you until those moans are replaced by the sounds of pleasure.

Then she opens her lips to take you into her mouth, but remembers that's what caused your problem in the first place. Smiling bashfully up at you, she continues stroking your cock with her hand until you eject the last of Ashley's minty spit by ejaculating, adding your cum to Tibby's waterlogged tank top.

Tibby stands up and kisses you on your cheek. "I'm going to take off these wet clothes. You get out there and let Ashley know she hasn't damaged your goods."

Grabbing a towel, you step out of the shower and find Ashley sitting on the closed toilet, from where she was able to watch Tibby take care of you through the glass wall of the shower cabin. She looks aroused, but plagued by guilt. "I'm so sorry John!"

"It's ok," you reassure her. "I mean it still hurts a little, but you didn't know that would happen. Now we know."

"And knowing is half the battle!" the wet and naked Tibby shouts as she emerges from the shower.

You look at her in surprise. "Last week you'd never heard of Airbud and now you're quoting GI Joe?"

"Just because I didn't know about your dumb dog movie doesn't mean I'm totally ignorant," she says indignantly.

Ashley looks back and forth between the two of you before bursting out laughing. "If you can argue with her about that you must be feeling better. But I still feel really bad about hurting you. How can I make it up to you, master?"
