Your sister:

You stare wide eyed at the door, panic settling over you as you hear keys rattling in the lock. There are only a few people with keys to the house, and the only one not currently home or out of state is your sister.

You start to get up, hoping to make a break for the stairs but you feel your mom’s foot step down on your leg, pinning you in place. You look up at her fear in your eyes, meeting excitement in hers. You aren’t sure why she isn’t panicking, her daughter was about to walk in to find you dressed like a femboy cat with her standing over you, strap on still on with only a bra besides it.

“Hi mom, I’m home!” You hear your older sister’s voice as the door opens, a rush of cold air from outside washing over you.

“Mona, it’s so nice to see you. I didn’t realize you were going to be home tonight,” Your mom says in a casual tone that does not match the current situation.

You’re waiting for it, any moment your sister is going to freak out.

“I wanted it to be a surprise,” she says, you hear her walking over, “I’m just here for the week, there was an issue at college so classes were cancelled until the problem can be fixed.”

Your face is down, eyes closed, but you can still tell your sister has just walked up and hugged your mom as if everything was normal, but then you hear something you had really not expected, that makes you turn your head to look.

Above you, your mother and sister are kissing, no, making out is a better word for it. Your eyes go wide as you see that your sister is wearing a skirt, and nothing under it, and your mom’s strap on is currently between her thighs.

They pull away and your sister looks down at you.

“So this little pervert is my sister now?” She asks.

Your blood runs cold, your mom had been talking to her about what she was doing to you.

“Yes,” your mom says happily, “though at the moment she’s the family pet.”

Your sister crouches down, legs spread wide at your eye level.

“Well in that case, normal kisses are only for family. Since you’re just the pet you have to kiss me here instead,” she says tapping her finger above her clean shaven pussy.

Your eyes jump between your mother and sister.

“I’m waiting,” your sister’s voice comes out annoyed.

Your mother takes her foot off your leg, and you crawl forward, kissing your sister on her clit.

“Good girl,” she ruffles your hair, then stands turning to your mom, “I’d love to have a discussion with my sister if that’s okay with you mom?”

“Of course, I told her while she’s in this outfit she’s a pet, so feel free to bring your stuff up to the room and in the meantime she’ll get changed.”

“Sounds good,” Your sister went back to the door, grabbed her things, and headed up stairs.

Your mom, crouched down, resting her hand on your ass, fingers finding their way to the fleshlight plug you had in.

“Such a shame, I guess we won’t get to test this pussy hole out tonight. Don’t worry, there will be another time. For now, go up to your room and strip. Stay naked in your room, and we’ll come get you. Nod if you understand.”

You nod, then go to stand up, but she steps on your leg again, keeping you down.

“Pets don’t walk on two legs, while you wear that outfit you will crawl.” She released you, and went back to the table.

Crawling this time you made your way up the stairs, the plug reminding you of its presence each time you lifted your leg for the next step.

By the time you made it to your room you are practically panting. But you go in and start pulling the outfit off, bit by bit. Until all that is left are the tail and the panties, grabbing the tail you start trying to pull, immediately you can feel the pain of your asshole trying to stretch for the bulb of the plug. Letting out a grunt of pain you pause, breathing hard against your bed.

You give it another try, making it a bit farther this time, but again stopping when it hurts too much. You’re panting hard when you hear your sister’s voice from the hall.

“You know, you’re going to need more lube if you’re gonna get that plug out,”

You turn in panic to your sister as she steps into the room.

“Mona, I…” you don’t know what to say.

She waits for you to continue, but when you don’t say anything else she smiles and walks over.

“So you're my sister now,” she reaches down, and helps you up to sit on the bed. Which is a bit uncomfortable with the plug still in.

You nod, eyes down.

“I’m so happy! Now you can join mom and I when we do girls night. And we don’t have to hide anything around you any more, it’s going to be so much fun!”

You look at her head cocked, you don’t think you have ever heard her so bubbly before. You’re about to question her when your mom walks in.

“Are you still wearing your cat tail Everly?”

“She can’t get the plug out,” Mona says.

“Oh no, well, we can’t have you wearing the house pet tail while we talk about things, I’ll be right back.”

You both wait as your mom walks to her room, there is a bit of rustling, then she comes back with a different tail, this one looked more like a wolf tail. You aren’t sure what you had been hoping she would bring back, but this wasn’t it.

“Stand up and turn around Everly,” she says, stopping a few steps shy of you.

You do as told and feel her reach down, there is a clicking sound as she unhooks the cat tail from the plug. Then another clicking as she attaches the wolf tail, then the horrific sound of a small padlock being locked in place.

“There, much better,” your mom said, “the cat tail is for when you’re a pet, can’t have you wearing it and talking now can I?”

“But then what’s the wolf tail for?” You ask.

“Well, you’ll need a syringe of lube in order to get that plug back out, which means you’ll need to go buy both. So that tail is gonna stay on until you do that. Not because you're a pet, but because it will embarrass you, and you need to get used to everyone staring at you, since you’re a girl.”

“You’re going to make me wear a tail until I buy stuff to take it off?”

“Yup,” she smiled gleefully, “You’d better go early in the morning if you want it out fast,” she laughed, “Mona come see me once you’re done talking to your sister,” your mom made a lewd display of gripping her strap on and giving it a pump, before blowing a kiss and leaving the room.

“You gotta help me get this out,” you say, turning to your sister.

“No way, you look so cute with that tail wagging behind you,” she giggles, standing up and walking uncomfortably close to you, “Now that you’re my sister, how about a proper hello kiss.” She pulls you into a tight hug, one hand gripping your ass, the other pulling your head into a deep kiss.

Your mind is racing as your sister’s tongue explores your mouth. Meanwhile the thought runs through your head over and over again. ‘THIS IS NOT RIGHT.’ Finally she pulls away, and holds you in place for a moment longer, smiling at you.

“I look forward to getting to know you as my sister now that you’re finally coming out, feel free to come to me for any girl advice you need Evy,” she smiles and lets go, “we’ll have to catch up a bit later, for now I’m gonna go get my pussy wrecked by mom,” she says in a cheerful voice that sounds wrong accompanying the words she just said.

You watch your sister practically skip out of your room.
