Late on Sunday evening, Ellie receives a message from her domme. "Are you thinking of me right now?"
Ellie has just turned in for the night. She puts her bedside lamp on and sends back, "Yes, ma'am." She was. Her domme occupies most of her free thoughts now. When she's drifting off to sleep, she often wraps herself up in thoughts of Miriam. Her sensual, womanly body, her lush curves... and her creativity, and her voracious appetite for sexual domination. Ellie likes the warm, comforting feeling of being fully owned by another woman. It constantly turns her on... which, because she's not allowed to pleasure herself without permission, drives her crazy.
Miriam starts a video call. Ellie scrambles for some headphones. It's very late, and she doesn't want to disturb her housemate in the next bedroom.
The video seems to be taken from Miriam's perspective, in Miriam's bedroom. The video starts out pointed at a low table, where a forest of BDSM implements is laid out to select from: plugs, dildos, vibrators of all shapes and sizes, clamps, floggers, and things Ellie can't immediately identify. The video pans across them, slowly. In the background audio, there is the sound of whimpering.
Slowly, the video pans around to Miriam's bed. There is a very petite, dark-skinned girl bound severely in the center of the bed: Miriam's other sub, Ellie's sister sub, Simone. She is lying on her chest, with a strange kind of black latex mask wrapped around her face, covering her eyes, nose, mouth and ears, but not her hair. Her face is a completely featureless shiny surface, framed by her chin-length bob of silky black hair. It's a very odd look.
Her arms are tied behind her in a long, elaborate bind, using red rope. The bind pulls her shoulders back and toward one another. Her elbows are roped together, and her forearms and wrists too, so that her palms meet near her bottom. Her legs have been bent double and her ankles tied to her upper thighs with more red rope, making her legs into useless knee stumps. She squirms, helplessly, as Miriam slowly circles the bed, studying her struggling form.
Ellie swallows hard.
The camera moves up beside Simone. "Roll over a little," Miriam says, and Simone grunts as she obliges. Miriam bends down and focuses on her exposed breast. Simone's usual barbell nipple piercing has been replaced with a fierce black butterfly clamp. There is a chain which leads from the clamp underneath Simone's chest, presumably to an identical clamp on her other nipple. Miriam toys with Simone's clamp a little, then gives it firm tug, pulling her nipple out away from her chest, showing just how tightly the clamp is biting. Behind her mask, Simone whines with what could be pleasure and could be pain. Her voice sounds muffled. It sounds like she's gagged somehow.
"A pair of my used panties in her mouth," Miriam explains.
Miriam lets Simone lie flat on her chest again. She moves around to behind Simone, and up between her spread thighs. There is a bright red object lodged in her anus, a butt plug or some kind of dildo. It's fat, at least two inches across. It's impossible to know how long it is, how deep inside of Simone's body it goes, but Simone has a fetish for extreme penetration, which means it's probably huge.
"Up on your knees," Miriam orders her. "Show the young lady what you've got." Simone raises her ass up and Miriam focuses down on her pussy, now, showing that there is a third, identical clamp screwed onto her fat pink clitoris. Miriam gives it a firm tug, just like the one on Simone's nipple. Simone shrieks with pain. It's wound just as tightly as the others.
"As you can see," Miriam whispers, "we're about ready to begin."
The whole scene is so erotic, it makes Ellie want to scream. She sits cross-legged in bed, watching on her phone, spellbound. She does not touch herself -- she's forbidden to do that. Her body is Miriam's. Her orgasms are Miriam's. Instead she keeps her free hand behind her back, balled up into a fist, to stop herself. She feels red-hot. She would give anything to trade places with Simone right now.
Miriam slides one finger into Simone's pussy. Simone whimpers and her body undulates against her domme's hand, and they set up a soft, pleasant rhythm together. Simone's clit clamp dangles from her raised pussy, tugging on her clit with its weight, dragging on the bedsheet. It must hurt like hell, but it seems to turn Simone on.
Miriam twists her hand a little, going a little deeper, vigorously stroking Simone's frilly inner labia. She works fast. She knows exactly what to do to drive Simone wild. Ellie has experienced manual pleasure from her domme many times, but she's never seen a close-up of what she actually does, not from this angle. Miriam turns away for a second, and dips her hand in a bowl of massage oil on the nightstand, and then continues to stimulate her bound lover, massaging her inner thighs, and then stroking her smooth mons pubis, and then going inside of her, curling her fingers down, looking for her G-spot. She does the whole thing one-handed, holding her phone with the other. She never turns the camera to face herself; Ellie never sees Miriam's face, or what she's wearing.
Simone's gasps become heavier and more urgent. She struggles against her bondage. Ellie is becoming uncontrollably wet. I want to be her, she thinks. I want to be with her. Ma'am has two hands, why can't she do this to both of us at once?
More lubrication. Another strong tug on the clit clamp, and then Miriam bunches her fist up and pushes it all the way inside of her sub. Simone screams, sharply, then her scream trails off into a moan of ecstasy, as Miriam pushes her hand deeper still, almost to the wrist bone, fingers bunching against Simone's cervix.
Ellie knew that Miriam fisted Simone on a regular basis, that it was Simone's absolute favorite. But she almost didn't believe it was true until right now. Simone is such a small woman, it's amazing that someone's whole hand can fit inside of her. It must feel so wonderful, Ellie thinks, to have ma'am so deep inside of you, stretching your pussy so tight...
Simone closes her thighs up, pulling Miriam in. Miriam fist-fucks her for a long, sloppy few minutes. Lube and juice ooze out from the tight seal Simone's vagina makes around Miriam's wrist. Simone wails continually, with ascending pleasure. And frustration. Her body, like Ellie's, belongs to their domme. And so Simone, like Ellie, is not allowed to come without permission. In her current state, she can't even beg for it. What must that feel like?
Ellie knows how it feels for her, at least. "Ma'am," she begs, "please may I come!"
Miriam ignores her at first. She fists Simone more vigorously, then pulls her fist all the way out, and then drives it in again, and again, roughly. Simone growls, and her body bucks. Her clit clamp swings against her domme's arm. She loves it.
Then Miriam slows, and withdraws, hand dripping. Simone's pussy closes back up. She mewls sadly.
"One of you may come," Miriam says.
"I choose her," Ellie says, immediately.
"...You're sure?"
"Make her come for you, please, ma'am! I want it. I want to see it."
"...Very well." Miriam plunges her hand back into her petite sub, and rails her harder than ever. Simone screams, and writhes, and soon comes hard, drenching her domme's arm with squirted juice, almost hitting the camera. Miriam withdraws, and fondles her ass. Simone falls limp, pussy still twitching. Miriam slowly backs away from her, leaving her lying there, contorted and thoroughly pleasured.
Ellie, watching, blushes and trembles with delight. Second-hand, frustrating, vicarious delight. She could have taken the orgasm herself. God knows she needed it. But how could she let her domme drive Simone to the edge, and then deny her? It would have been too cruel.
It'll be her own turn soon enough, she knows. Well... she hopes.
"Young lady," Miriam says, "from now on, when you think of me, I want you to think of this. Us. Of me, railing your bound sister sub. All night. Every night."
She ends the call.

On Monday evening, after work, Ellie heads to the office gym. There are quite a few people using the gym, although Ellie knows that by the time she's done the place will be empty except for her. The gym is open twenty-four hours a day, and she normally works out for three hours. No one else stays around for that long.
Ellie turns heads when she works out. In her life, she's always drawn attention because she's always been very tall, and very beautiful. But when she's in workout gear, and especially when she's working out, everybody looks. Today she wears bright blue leggings and a skimpy white sports bra with a strappy back. Her back is a network of muscle. She has abdominals like a stack of bricks, and immense trapezii and deltoids. And, within a quarter-hour of her beginning her workout, every inch of her is gleaming with sweat.
So, it's impossible not to look. But Ellie ignores most of the attention. She focuses on her workout. She puts on podcasts, and tunes the world out, and works.
Miriam arrives about an hour later. As the office's executive manager, she works a substantially longer day than Ellie. By the time she arrives the gym is half-empty. She carries her usual kit bag over one shoulder. With her other hand she tows a piece of wheeled carry-on luggage, which, to Ellie's eye, looks pretty heavy. She gives Ellie a cordial nod as she heads straight for the changing room.
A few minutes later she emerges, changed. She wears her usual black and pink fitness gear, with her hair pinned up into a pony tail. Ellie is in the middle of a set of pull-ups when Miriam approaches her. Ellie stops.
