Mum

Little Girl. Tomorrow, you will send me a video, at least five minutes long. You will be standing by the window, natural light shining on your body (the forecast is sunny tomorrow, and I want to see that cold winter light on your porcelain skin). You will be masturbating the whole time, but remember that you are still not allowed to orgasm. You will have clothespins attached to your nipples. I know how long you can make them for me, there should be plenty for the clothespins to grab onto.

For the first couple of days after the funeral, the sisters barely got out of bed at all. They were both devastated, and spent most of their time hugging and crying together, talking and sharing memories of their mother. Ada would kiss the tears away from her little sister's cheeks, and Lily would do the same for her. They lay all day in their mother's queen size bed, finding some comfort in each other's warm bodies.

As their eyes met, Lily smiled shyly. "I love you," she said, having wanted to say this to her big sister for a long time, but not being able to. Only now had it become possible.

"I love you too, sweet sister." Ada held Lily as tight as she was able, delighting in the feeling of her soft body. "You will always have me. You won't be lonely, not ever. I won't allow it."

Holding her sister like this, Ada was surprised when she felt two hardening nubs pressing into her chest. It seemed her sister's nipples were becoming aroused.

She let go of her sister a little bit, wanting to look her in the eyes questioningly, but Lily turned her face away.

Seeing Lily's embarrassment, Ada pulled her back into the hug.So what if she's horny,she thought.Isn't that a good thing, actually? It's a sign that she isn't depressed, at least. I've been so worried about her falling back into depression, but maybe I don't have to be so worried about that... She just needs to know that I accept her completely, that there's no need to feel embarrassed.Ada nuzzled into her sister's neck, giving her light kisses, caressing her back. "I really love you so much. You're the best sister I could ask for. You're just perfect."

Lily was wearing an old, lime green t-shirt, worn thin with use. There were several small holes in the back, and every once in a while, one of Ada's fingers would get caught in one, letting her feel the skin underneath. Their smooth legs were rubbing against each other, as the sisters did their best to touch each other with every part of their bodies.

Anyone would agree that the sisters were beautiful. Not like glamour models, but in the way that real young women often are. Lily was long and slender, with delicate facial features and short, very light blonde hair. Some might say she seemed underdeveloped for her age, with small breasts and relatively narrow hips, but she had very nice muscle tone in her thighs and calves, and a firm behind that sometimes made her big sister a little envious. Ada herself had more rounded features, all smooth curves, soft, large breasts, and a meaty backside that she disliked herself, but which made onlookers smile secret smiles when she walked past. Her face was larger-featured compared to her sister, but very memorable, with an upturned nose, and lips that were unusually full and inviting.

Apart from the old t-shirt, Lily was wearing a pair of simple ash grey cotton briefs, which fit her snugly and was very soft to the touch. Ada, however, was completely nude. She had started sleeping in the buff maybe three months ago, and was already getting so used to it that she could be in bed with a family member like this and only feel slightly weird about it. Something about being naked felt very right to her.

The nudity wasn't really a choice for Ada, though. It was a requirement. She had made a promise to her new girlfriend that she would always be nude in bed, and she was keeping it.

Lily had started to cry again, and Ada intensified her kisses and caresses.

"I don't deserve... to have someone... love me like this... I don't... deserve you."

Ada had never loved her sister more than she did in that moment. "But baby girl," she laughed, "it doesn't matter what you deserve. I mean, youdodeserve to have me. But even if you didn't, it wouldn't matter, because I will love you no matter whatyouthink about it, no matter what you think you deserve. There now, just let it all out, get all that nonsense out of your system..." And Ada continued to kiss and hold the person she loved most in the whole world.

Little Girl. I cannot get over the sight of you in your little thong. In tomorrow's picture you will be wearing the longest pair of socks you have, knee-length if possible, and that delicious thong. Nothing else. Let's say the picture is taken outside somewhere. Your choice of location. Don't say I never give you agency.

***

They stayed like this for at least another hour. Lily sobbing quietly, bathed in her sister's love. Over time, as Lily became calmer, Ada could actually feel her sister's heart rate slow, because of how tightly their chests were pressed together.

Ada's large breasts were compressed and flattened as they pushed against her sister's smaller, firmer ones, and after a while she once again started to feel those two hard nubs pressing into her own soft flesh. She pecked Lily on the lips, and then held her gaze for a long time, smiling, communicating without words thateverything about you is all right.Lily then reciprocated the kiss, and their lips moved softly against each other for a long time.

The nubs pushing into her were becoming even harder now, and Ada could feel her own heart rate start to rise. She didn't even mind the sexual tension. It didn't worry her at all.So what, she thought,we can fuck if that's what we want.It would only make their relationship even closer, and that's what they both wanted; it's what they needed. Lily's hands were grabbing Ada's naked ass now, kneading her buttcheeks, spreading them apart and pushing them back together, creating a delicious sensation as her asshole was stretched and then allowed to relax, stretched and relaxed... Lily's crotch was absolutely soaked, pushing and rubbing against Ada's thigh... Ada opened her mouth...

And then Ada's phone rang. Her eyes shot open. "I'm sorry, honey," she mumbled, stumbling out of the bed, stumbling out of her sister's affections, "I love you so much, but if it's Siobhan calling, I have to take it, it could be her..."

She practically ran into the living room, still stark naked, big tits flopping about. She had accidentally left her phone on the coffee table last night! Stupid Ada! Stupid stupid stupid! You should always keep that phone within arm's reach, you know this!

Of course it was Siobhan. Just the sight of her name on the screen was enough to make Ada feel dizzy, and filled with dread, and like she was flying and falling and everything at the same time.

"Yes, it's me! I'm sorry I was so slow to pick up!"

"That's fine. You are forgiven." This was said in that voice that Ada knew so well, the one that made you feel small and very grateful.

"It's so good to hear your voice...Thank you very much for calling, Mistress."

Ada could practically hear the wicked smile on the other end, as her Mistress left a silence to drag out for a while. She realised that she had a hand between her legs, gently massaging her labia. She was moist and warm. Her hand had just started doing that all on its own.

"How are you holding up, Ada?" The voice was gentle now.

That question was difficult to answer. Because right now, Ada felt amazing, horny and jittery, but that would be wrong to say, now, just a few days after her mother's funeral.

"Well, you know... I think I'm getting better. I'm still very sad of course. I don't know, it feels like I'll probably be a little sad forever." This was true, she actually did feel that way. Under the horniness, there was still a very strong undercurrent of grief.

"Yes, I think it's possible that you will never heal completely from this. It's a huge loss, and you're still so young. I'm very sorry this is happening to you."

Her vision was getting blurry now, tears welling up in her eyes. "I'm so lucky to have someone like you to help me through this. I'm so happy that you found me, Mistress." Even though she was crying, her left hand kept moving autonomously, rubbing the vulva, thumb occasionally teasing the clit.Like a good girl.

"You actually sound a lot better."

She didn't know how to respond.

"How is your sister doing?"

"Ehm..." Didn't know how to respond to that either.

Ada had been standing up so far, and now decided to sit down on the sofa. Then she realised she would make a stain (she was so fucking wet already) and she quickly pulled over the tartan wool blanket to sit on. It would at least be easier to wash a blanket than the upholstery. Her mum would be less pissed.

And then she realised no-one would be pissed with her. Her mum wouldn't be coming home from work smelling of burnt grease and wood-smoke. She wouldn't be calling out from the bedroom that it was time for her medications and could you come get them for her.

Her mum would never be pissed at her again.

Everything had changed, and inside Ada was a chasm impossibly deep.It should be impossible to hurt this much.

"Ada? Are you there?" The voice that made you feel small was talking to her, and now it made her even smaller, like she wasn't even there. And in a way, that was a relief, to feel like she wasn't there at all. Just some servant, nothing more than that. Subservient to a towering Mistress, immensely greater and more important than herself.

"Yes, Mistress. I am here." Her own voice sounded distant and mechanical to her now. This was good. She could be like this.

"Oh... Is it better for you to be fully submissive right now?" Siobhan had immediately picked up that something was wrong.

"If it pleases you, Mistress."Please make me disappear.

"Okay, I understand. Well, then... Let's hear, have you held to our agreement?"

"Yes I have, Mistress. I have been naked for you every night, as you asked."

"That's very good. You're a very good girl. And... has your sister been in bed with you?"

"Yes, Mistress. Yes, actually, we have spent a lot of time together in bed. And we have slept together every night. Well, both nights I mean, both today and the day after the funeral."

"That sounds lovely. But, I'm sure you remember, our agreement is that you will always be naked in bed, whether I am there with you or not."

***

Little Girl. I want to see what my gift looks like inside you. Show me in tomorrow's picture.

***

Lily was standing in the door to the living room now, looking worried. She had heard something strange happen to her sister's voice, even from the bedroom with the door open she could hear that something was wrong, and she had come in to see what was happening.

***

Little girl. I want us both to remember what I did to you. Tomorrow you will send pictures of the marks I left on your body.

***

"Little girl. I hope you aren't ignoring me."

"Sorry, Mistress. Yes, I remember. I stayed naked the whole time."

Lily's eyes grew wide with surprise and confusion.

"Little girl, you know that answer isn't good enough."So small. Ada was infinitely small, and forever shrinking."Try again, with more detail. And I hope you are touching yourself."

That was the most recent rule Siobhan had come up with.When we talk on the phone, you will be touching yourself. A hand under your bra, or in your knickers. No matter where you are, or who can see you. Agreed?

Ada tried to look apologetically at her sister, but she didn't know how to. Her fingers started mechanically playing with her labia again. They were still quite swollen. She couldn't stop looking her sister in the eyes.

"I apologise, Mistress." Her voice was shaking. "Yes, I have been naked in bed with my sister. We spent a lot of time together in bed, and I was naked the whole time. Just as I promised." She tried a kind of smile and a shrug, but it was like Lily didn't even see her. She was just standing there in shock, eyes wider than ever, her mouth actually hanging open. Some small part of Ada was awake enough to thinkshe looks really cute like that. Nipples still visibly hard through the thin lime shirt.

"Good giiirl. Tell me what your sister was wearing."

Still, Ada and Lily's eyes were locked together, both of them seemingly unable to look away. "Ehm... Well..."

"Ada! Stop it with theuhmingandahhing,you know it makes you sound like an idiot! When I speak to you, you will answer directly, clearly, and immediately. In complete sentences, understood?"

"Yes, Mistress."

"So tell me what your sister is wearing when you sleep naked with her."

"Yes, Mistress. She was... I mean today she is wearing a green t-shirt and grey cotton briefs."

"Mmh, yes. Are the briefs snug?"

***

I like those sunset colours on your luscious arse, Little Girl. Show me again tomorrow, I want to see how they develop.

***

Lily was blushing furiously by now. Her cheeks were getting pinker by the second, her mouth still hanging open. Inside her head, she was still struggling to understand what was even happening. Was Ada really describing Lily's underwear to... her girlfriend? This must be her new girlfriend on the phone, right? This was someone Lily hadn't even met yet and knew practically nothing about. Why was this happening?

***

Tomorrow, keep pinching your nipples until you cry, Girl. I want to see your tears.

***

"Yes, the briefs are perfect for her. Her ass looks amazing."

"Does your sister have a tight ass?"

"Yes, my sister has a tight ass. It's actually just as tight when she isn't wearing the briefs. She's a runner."

"You've seen her naked?"

Still staring straight at each other.Just be small, Ada kept thinking."Yes, I saw her naked yesterday."Just don't be anything at all."She was going to take a shower, and she just took her clothes off right in front of me. We were in the bedroom."

"How old is she again?" Siobhan was moaning the words now. Probably masturbating.

"She turned 18 in December."

"That's absolutely lovely. Don't you feel lucky that you get to watch your little sister naked?"

"Yes, Mistress. I feel very lucky that I get to watch my little sister when she's naked. Her teenage body is so hot and firm, and I feel very lucky when she shows herself to me."

Lily's whole face was just flaming red. Ada felt incredibly ashamed, but there was no other path for her, she had to just keep pushing forward into the unknown. There was a gaping abyss on both sides, but she could trust in her Mistress. Siobhan would guide herinto the dark.Where you will be tiny and invisible.Ada's hand began to move faster between her legs.

"Tell me what you do together in bed. How much are you touching each other? Are you kissing? Oooh fuuck... Please tell me that you kiss in bed."

"Yes, Mistress. We hug each other when we cry, and caress each other, and kiss away the tears. And just before you called, we... we were kissing on the lips, and... I mean, it's normal that we kiss each other goodnight, we're sisters, we've always done that..."

"Ohmygod, that's so beautiful. I love that for you. You should always be kissing your sister..."

"Yes, Mistress."

"Yes, that's right! Ooohmygoood. That's a new rule... From now on you should kiss your sister on the mouth when... Jesusfarkingchrist... When you're together, whenever you get the chance. Mmyeah, kiss your sister... Where is she now? Are you still at the house? Fuckfuckfuck..."

"She's right here, Mistress. She's, I mean she's looking at me."

The phone went completely silent.

But not for long. When Siobhan's voice came back, it was almost joyful. "My god, you little slut! Youknowthis is allyourfault!... Wait, does that mean you've been masturbating in front of your sister?"

"Yes, Mistress." Just when Ada thought she couldn't get any smaller, any more humiliated, somehow everything managed to get even worse.

"That's hilarious! Oh my sweet! And you're still doing it?"

"Yes, Mistress." Ada inserted a finger into herself.

"That's so funny, I almost don't blame you for ruining my orgasm."

All of this time, the sisters had been completely focused on each other,the whole world has dropped away,and all that existed was two horny, humiliated girls, and the cruel voice in Ada's ear. Ada was extremely wet, her pussy was so ready to be fucked, and her sister looked like she was about to start moaning. She inserted two fingers, pushed them up as far as they would go. "I'm so sorry..." Ada began to say, intentionally humiliating herself even more.

"Shut up. You'll pay for it later, I promise. Now, put me on speakerphone. I want to talk to your sister."

Incredibly, without even thinking about it, even though it felt like an earth-shatteringly bad idea, an absolute and certain catastrophe, Ada's finger hit the icon on her iPhone screen.

Siobhan started talking immediately, like she knew that Ada would obey without hesitation.Of course she knows. There's nothing I wouldn't do for her.Ada started finger-fucking herself in earnest.

"Heeeyy Lily, haha so that was a bit embarrassing wasn't it?"

While Ada was giving her little shame-slut masturbation show, Lily's hands had been moving slowly towards her own pussy and right breast, but when she heard Siobhan's voice she froze immediately (Ada kept going, slut that she was), then Lily's hands flew to her sides, like she was some army recruit and Ms. Ó Ceallaigh was a drill sergeant screaming at her to stand at attention.

When actually, the older woman's voice was quite pleasant. She had changed her tone once again, and spoke almost soothingly to her lover's sister. "I just want to say that I'm very glad Ada has such a close relationship with her sister. Especially now, I'm sure you need each other. I don't judge you for anything that's happened or might happen in the future, okay? I'm really not in a position to judge anyone anyway... Lily? Are you there? Ada, did she leave the room?"

The only thing Lily could get out was a very small "Hello..." that Siobhan probably couldn't hear at all.

Ada managed to gather herself enough to be a big sister again. "Yes, she's here. Just a minute, I'll get her closer to the phone." She stood up and went to Lily. Still having two fingers up her made it awkward, but she got there.

"Good girl, Ada.... By the way, I hope you've stopped masturbating. Youareallowed to stop when your sister is in the room, you must know that."

Ada did not know that.No matter where you are, or who can see you,that was the rule. It had been repeated many times. It should have been a relief to be allowed to stop, but all she could feel was even more humiliation.

My Mistress truly is a Queen.

"It's okay, Lily, come sit on the sofa with me." Her sister was stiff as a board, but relaxed just the slightest bit when Ada put an arm around her. She guided her stunned kid sister gently across the room, sitting her down. They sat close together, holding hands, pushing their cheeks together (both were still red hot with embarrassment).

Siobhan seemed to be waiting respectfully, giving them some time.

Lily was the first to speak. Her voice was very small. "Hi, Siobhan. I'm very pleased to meet you."

"Oh, you're sweet. I'm pleased to meet you, too. And I really am sorry. We were both very rude to you, I'm afraid, and in your own home no less."
