Twin Training

Hello hello. This is the first time I ever write anything, so don't expect a masterwork or something even resembling coherent grammar. I hope you find some enjoyment in it regardless.

This story will feature incest, bondage, denial, anal, humiliation and consensual-nonconsent.

Character Intro

Dana (Toy) & Kara (Plaything): Age 25 - twin submissive sisters

Krista: Age 27 - friend and occasional mistress of Dana & Kara

------------------------------------------------------------

Day 1 - Thursday

It had taken a while to set it up properly, getting each of the girls here without the other knowing. They thought we were going to start playing tomorrow, but I had decided to start out early.

Boundaries were going to be pushed this coming weekend. They had each given me suggestions and requests for things they would like to try. Surprisingly enough, or maybe not considering they are identical twins, they had mentioned almost the exact same things. There was three in particular that I would be able to intertwine into a beautiful session. Humiliation, non-consent, and most surprisingly: incest. This was going to be fun, and it was starting right now.

Both girls were naked, masks covering the top half of their faces, including their eyes so they couldn't see, ring gags and noise cancelling headphones on. The headphones had been expensive, but worth it, with build in speakers so I could give instructions. They didn't even know who their partner was going to be in this session, besides me. But that would soon change.

Kara was on her knees in the middle of the bed, hands cuffed behind her neck to a collar, ankles bound to each side of the bed and the collar attached to a hook in the ceiling, preventing her from moving. Dana was standing at the foot of the bed, wearing a strapon, one of those with a head for the one wearing it as well, waiting for my instructions. Both had chains attached to their nipple piercings, which in turn was connected to their clit piercings by a second chain. Small weights were attached to both nipple and clith piercings. Light enough not to hurt, but heavy enough to remind of their presence when they moved.

I moved onto the bed with a bottle of lube, and squeezed out a healthy amount to prepare Kara's ass, feeling her tense up briefly at my fingers intrusion, before relaxing.

After fingering and getting her ready, I turned around and lubed up Dana's strapon, before sliding off the bed.

I spoke to Dana: "Come Toy, show your Mistress what you got. Fill up her ass"

Dana crawled up on the bed, hesitantly seeking with her hands before finding Kara and eagerly moved into position, before positioning her strap-on and gently pushing forward, Kara grunting in discomfort at the initial intrusion.

"Take it like the slut you are, Plaything. Be a good girl" With a moan at my words, she assists by pushing back and before long the cock is fully buried in her ass.

"Good Plaything." I say, as I crawl up behind Dana, I position myself behind her and lean into her, feeling her movements as she thrusts into Kara

"Isn't this exciting? Not knowing who you're fucking?"

I push Dana further forward until she's sandwiched between Kara and I, preventing her from doing more than small, jerking thrusts.

"Play with her tits, pay special attention to her nipples. We're going to put her to the edge and keep her there until I get tired of it. Don't move from your position, Toy."

Dana grunts in confirmation, as I move over in front of Kara and start fingering her pussy and mouth. As I start speaking to her I switch hands, filling her mouth with the taste of herself.

"Do you wonder who is fucking you, Plaything? Maybe I'll tell you later. Maybe not. Maybe you know her. Perhaps it's one of our friends, or one of your co-workers."

Kara is now moaning continuously while pushing back as much as she can, as my words register and push her towards the peak in combined effort with my fingers and Dana's ministrations.

I pay close attention to her tells, and as her pussy starts clenching and her voice break into tiny squeaks I quickly remove my fingers, to her audible protests, before she can tip over the edge.

"Bad girl, not yet, not without permission. You know better Toy."

Kara let out a small keening wail, before pushing even harder into Dana.

"Oh, you enjoy that! Well, I already knew you were a pathetic whore. But I didn't think you'd get off that hard on being ass fucked. But that's just it, isn't it? You hate it and it makes you feel dirty and nasty. It makes you feel like you truly are. A filthy whore, a nasty little Toy that gets off on being humiliated and forced to do the things she doesn't have the courage to ask for, isn't that right Toy?"

The more I speak, the hornier she becomes. I can see her pussy clenching and twitching and I quickly tell Dana to stop fucking her.

For the next 30 minutes, I use Dana to help bring Kara to the edge repeatedly until she's a sweaty, drooling mess.

I instruct Dana to pull out and kneel by the bed as I free Kara from the chain to the ceiling and uncuff her hands before guiding her down on her back, finally letting her rest a bit.

I order Dana up on the bed again and guide her into a sitting position, with her left leg over Kara's right, and her right leg under Kara's left, their pussies only a few cm apart. I grab two double ended dildos and put them down on both girls, before I give Dana the same lube treatment as Kara received, and order Kara up in a sitting position as well.

I take off their headsets and sit down in my chair, before for the first time addressing them both directly.

"Alright sluts. Time to get connected. You can feel two double ended dildos. If you manage to get both inserted into each of your holes and have your pussies kiss in under a minute, you will both be allowed to orgasm during this session. Time starting: Now!"

Perhaps it was a little mean to remove their headsets first. The initial confusion lost them a few seconds, but before long they were both frantically working each dildo into themselves.

My plan was to have them worked up enough, desperate enough, that it would take time before they realised each others moans were familiar. Hopefully they wouldn't realise exactly how familiar until the end, but it would be fine if they did.

Luckily for both, they made it with time to spare and was soon grinding into each other, moaning in concert. I moved up beside them, and loosened the buckles on their masks, so I could easily remove them when it was time. A time fast approaching, as they raced towards climax.

I could tell they were almost there, but they wouldn't cum yet. Not before I gave permission. I watched, and listened to their moaning and panting, the wet sounds from their pussies as the ground into each other, listening at they grew increasingly desperate to cum, waiting for one of them to break.

And then it happened. "Mistress, please!" Kara tried to say through the gag, and in that moment I pulled off their masks while ordering "Cum for me!"

As their orgasms crested and crashed over them, the sisters stared into each others eyes.

"Surprise, girls. Smile for the cameras."

Note: This took me ages to write, so while I can promise the next part will come out eventually, I have no idea about a timeline.
