Dominating to the Family

The following day at lunch time I found myself a private corner of the computer lab and checked the video, it was so fucking hot I nearly creamed my pants there and then. I typed out another message and timed it to send during dinner again.
The rest of the day passed uneventfully, although the car rides home were getting very quiet, so quiet even Sarah noticed. When we were just about to sit down to dinner I “realised my battery was low” and plugged it in to charge in full view of everybody. Maria had just finished her dinner when her new set of instructions came through. She ignored it until after she had done the dishes and went to her room to “study”.
“Well done, you are turning into quite the submissive slut. I think you’ll agree that I have more than enough to get you, your brother and sister kicked out of school, your mother fired and any chance of you getting into anything other than a strip club non-existent. So, I think it’s time to kick things up a notch. You are to call your sister into your bedroom and make out with her. Tell her the truth if you want, or make some shit up, I don’t care. But you will sit on the end of your bed and within five minutes, I want you using tongues to kiss each other. I want the video to be ten minutes long, give or take. I want it sent to me by 8 o’clock. Just kissing and you can both keep your clothes on, for now. Don’t forget to smile!”
WHAT THE FUCK! How could he expect her to do that? With her sister? She was just a child. If she was going to do it, she had less than two and a half hours get it done. She couldn’t allow her family to suffer the embarrassment of the photos getting out, she had no choice. And what did he mean by “keep your clothes on for now”?. That sounded ominous.
And what to tell Sarah? She decided to go with the truth, she knew Sarah worshipped her and would do anything for her. But she felt shitty doing this to her.
Maria went to Sarah’s room and knocked quietly.
“Come in!” shouted Sarah. Maria entered, close the door behind her, and walked over to sit on the bed beside where her sister was lying down scrolling through her phone.
“Can I talk to you for a minute sis?” she asked in a sombre tone.
“Sure, what’s up?”
“I need a huge favor, and I’m sorry to have to ask you this.”
“Oookaay?”
Maria took a deep breath and let it out slowly
“Here’s the thing. I took some nude photos of myself and somehow, this creep got a hold of them and is blackmailing me…”
“WHAT? You have to tell Mom!”
“Shush! I can’t. If I don’t do what he says, he’ll send the photos to the school board, get us kicked out of school and Mom fired. We’ll have to move, and none of us will get into college, our lives will be ruined. I have to do what he says.”
“… …”
“… …”
“What’s the favour, I’ll do whatever I can.”
Maria smiled fondly at her little sister; she had never loved her as much as she did right now. She took another deep breath and took the plunge.
“He wants me to send him a video of us kissing on my bed, for ten minutes, with tongues, by eight o’clock or he’ll send the photos and ruin our lives.”
Sarah hung her head shyly and told Maria a secret she hadn’t told anyone else, even her closest friend.
“I… I… I’ve never kissed before, not like that.”
“It’s okay, I’ll show you. I’ll be gentle, I promise.
“I don’t know, it’s weird.”
“I know, but if we don’t, he’ll ruin all our lives.”
“Okay.”
Maria hugged Sarah tightly with relief.
“Are we starting now?” asked Sarah.
Maria started laughing at the silliness of the question in the seriousness of the moment.
“No doofus, we’ll go into my room and do it there, I can lock my door.”
They stood up and walked back into Maria’s room, passing Devon on the way.
“It’s not a full moon tonight, why are the Bitches of Eastwick meeting tonight?”
“Shut up, dick head.”
“Oooh! Great come back.” He said as he entered his room.
They ignored him as they closed and locked the door behind them. They sat on the end of the bed, turned in to each other with their knees touching.
“Do you want to practice first, or just do it?” asked Maria.
“Let’s just do it.”
Maria got her phone stand and set it up on a chair close to the end of the bed. She adjusted the focus, started recording and sat down beside Sarah. She leaned in slowly, grasped Sarah’s chin gently and drew her in for her first kiss.
Their lips touched hesitantly at first, then with more determination. She dropped her hand to Sarah’s shoulder. They kissed like that for a minute or two before Maria pulled back.
“Okay, now I want you to open your mouth a little bit.”
Sarah opened her mouth a little and Maria leaned in slightly before stopping.
“A little bit more, that’s better”
Maria could feel the moist warmth of her little sister’s breath as she leaned in to kiss her. There was little hesitation this time. Although neither knew it, both were thinking of a boy they each had a crush on. Maria was thinking of one of the boys on the football squad, Sarah was imagining a boy in her class.
Both their cheeks were flushed with embarrassment. Neither had any particular desire for members of the same sex, going to a conservative catholic school meant that there was no teaching about LGBTQIA+ issues, but doing something so intimate with a family member was disgusting.
After a few minutes Maria broke contact again.
“Okay, this time open your mouth a little more, and when I kiss you, I want your tongue to play with mine. Just copy what I’m doing. It’ll feel weird at first, but it’ll only be for a few minutes, then we’ll be done.”
“For now.”
This time they leaned towards each other and kissed for the third time. As they kissed, their tongues danced and slid around. They frenched for a minute before Maria pulled back slightly and motioned to Sarah to stay where she was and stick out her tongue a bit further. She stuck out her own tongue, and from a distance of a couple of inches they tongue fenced for another few minutes. Finally, Maria pulled back and glanced at the timer on the phone. Almost ten minutes. She reached over and switched off the recording. She turned to Sarah.
“I’m sorry you that I had to drag you into this, I’ll make it up to you, I promise.”
“What happens now?”
“I don’t know, and I’m scared.”
Sarah got up, unlocked the door, and walked slowly back to her room where she lay on her bed and worried about what the future would hold for them now.
Back in her own room, Maria checked the recording before sending it to her blackmailer. She waited up until midnight for a message before falling into a troubled sleep on top of her bed.

The next day I was feeling generous, sorry, I misspelled sadistic, and did not respond, the same on Friday. I watched as Maria’s demeanour varied from slightly panicky to just short of a full-blown melt down. I waited until Saturday so that I could catch a ride into town with Mom. I went to a different café where I could sit down and check my burner phone in private. I turned the media sound to silent and downloaded the video Maria had sent. My dick got so hard as I watched my sisters making out that I was unable to stand up for fifteen minutes after the video ended.
I composed a message with additional instructions for Sarah and timed it to send to Maria while we were all sitting down to dinner. Then I met Mom for lunch and chatted for a bit while I figured how to get her involved. I decided to wait until I had Maria and Sarah in a more of a compromising position and use the threat of having Maria arrested for statutory rape and production of child pornography before getting her involved. She would do anything to protect us.
We drove home and I pottered around the house before ordering a takeaway. We had all just started eating when Maria’s phone pinged. She glanced at it and all the blood drained from her face as she read the message. Needless to say, her appetite was ruined, and she did little more than pick at her food before asking to be excused.
Maria was looking forward to having dinner, she had barely eaten since the blackmail started and she was starving. She hadn’t taken more than a few mouthfuls before her phone pinged. Out of habit she picked it up and read the message. She immediately lost her appetite and turned pale. The message read:
“That was fucking hot. Young Sarah is lucky to have such an experienced teacher. Tonight, you’re going to teach her a little more. She can remain clothed; she is however going to take off your clothes…”
Her mind refused to function properly as she read the rest of the message. This was absolutely sick. Her only problem was she was in too deep to stop now. The consequences of the photos and that video getting out were too horrible to contemplate. She played with her food for a bit, the nausea rising slowly inside her. She asked to be excused from the table and walked slowly until she reached the top of the stairs then sprinted to the bathroom where she barely made it to the toilet before throwing up the little she had for dinner.
She went back to her room and paced around for a bit until she heard a soft knock at her door and Sarah’s timid voice asking if everything was okay.
“No, can you come in?” she waited until Sarah had entered, moved behind her and locked the door.
“What’s wrong?”
“We have another… task!” she spat out the last word with enough venom to kill half the Eastern seaboard.
“First, he wants you to download an app called Telegram so I can send him your handle. He said he has some tasks for you to do solo.”
“What do you mean, solo? Like getting naked for him?”
“I’m sorry. I didn’t want to drag you into this, but I had no choice.”
She walked Sarah through downloading Telegram and noted her handle. She would send that with the next video. That was the easy part. She took a deep breath and relayed the rest of the instructions to her increasingly shocked sister. Then she showed her the message to puncture the incredulity of Sarah.
“That’s disgusting!”
“I know, but we don’t have a choice.”
Sarah sat down on the end of the bed and buried her face in her hands. She had seen other girls naked in the shower of course and had seen her sister naked on more than one occasion. This went way beyond that. She was terrified of how far this pervert would push them, but she realised that they were out of options. She sat up suddenly with determination.
“Okay, let’s get this over with.”
Maria set up her phone so that it could capture the action and pressed record. Then the depravity started.
Maria approached her sister, and they shared a long deep french kiss. When they broke the kiss Sarah reached up and started to unbutton Maria’s blouse. She tugged the tail free from the waistband of her jeans and motioned for Maria to turn around. She pulled the blouse off, Maria extending her arms behind her to make it easier.
Then she und the clasp of Maria’s bra and told her to turn around. They shared another kiss before Sarah dropped to her knees and reached for Maria’s pumps. Maria steadied herself with a hand on Sarah’s shoulder and lifted her right leg, allowing her sister to pull off her right shoe and sock. They repeated the process with the left leg.
Still on her knees, Sarah hesitated momentarily before undoing the button and zip of Maria’s jeans. She pulled them down around Maria’s ankles and stopped for a couple of seconds, unwilling to continue any further. She started to hyperventilate a little before Maria reached a comforting hand down onto Sarah’s shoulder.
Sarah’s breathing slowed down, and she looked up and gave a small nod of confirmation. Then she grasped the waistband of Maria’s panties and dragged them down to join the jeans. She couldn’t help but notice Maria’s shaved pussy and was momentarily jealous that she had pubic hair to shave.
Maria sat down awkwardly on the end of the bed to allow Sarah finish removing her clothes. They both stood back up and kissed again, Sarah feeling uncomfortable as she felt her sister’s breasts pressing against her slightly flatter chest. Again, they broke the kiss and Maria reached up her right hand and inserted her ring and middle fingers into Sarah’s mouth. Sarah sucked and licked the fingers lightly, trying not to gag on the unfamiliar penetration.
Maria sat back down and spread her legs as wide as possible, which for a cheerleader was quite wide. Sarah knelt down at her sister’s feet, folded her arms across Maria’s right leg and rested her chin on her arms. She was staring pointedly at her sister’s shaved pussy.
Maria started to masturbate slowly, her face burning red with embarrassment. She stared fixedly at a point on the wall just over the phone that was recording her degradation, trying her best to ignore the fact that her thirteen-year-old sister was watching her in this most intimate of moments.
Despite her lubed-up fingers, there was absolutely nothing erotic about this for her, so she closed her eyes and started fantasizing about the player on the football team. Unconsciously, her left hand reached for her breasts, and she started kneading and squeezing them. Eventually the combination started to work, and she could feel herself slowly building to an orgasm.
Her breathing started to get faster and turned into silent panting. As she approached climax she started to moan slightly, and she was forced to jam her hand into her mouth to silence herself. Suddenly she started to buck on the bed as she came, juices covering her hand.
As she started to calm down, her breathing returning to normal, the final instructions came to the forefront of her mind, and she felt like throwing up again. She looked down at Sarah who was staring with a mixture of fascination and shock.
Sarah looked up at Maria and realised what she had to do next. She got shakily to her feet and watched Maria stand up. Sarah grasped her sister’s right wrist with both hands and slowly brought it close to her mouth. She closed her eyes and steeled herself for what she was about to do.
She started to lick the juices off of Maria’s hand, choking on the tase of her sister’s cum. Then she sucked each of the fingers until there wasn’t a drop left. Then they kissed deeply again before turning towards the phone and forcing a smile. They waved at the phone and Maria stepped in front of it and stopped recording.
Immediately they both stopped smiling and started just stood there with a look of shock and stared at each other.
“This is never going to end is it?” asked Sarah, tears welling up in her eyes. “Whoever this is, is going to own us forever. And there’s nothing we can do about it.”
“We can’t believe that if we want to get through this.”
Maria stepped forward and hugged Sarah close to her, before realising that she was still naked after what had occurred. She released her sister quickly before pulling on her clothes again.
“Alright, I have to send this off to the creep. Let me know when he contacts you. I’ll help you. We’ll get through this together.”
“What are we going to do now?”
“We go downstairs, watch a movie with Mom and act like everything is normal.”
Maria sent the video along with Sarah’s Telegram handle to the blackmailer and took a couple of minutes to compose herself before heading down to the tv room.
