Synopsis: the youngest sister of a wealthy businesswoman is requested to take care of her daughter, an adult yet immature young lady. It all takes a twisted turn.

If there's anything Stephanie Kanto hated even more than just babysitting, it was babysitting her niece, Sophie. The gap of age was barely two years -Stephanie was 22 and Sophie was 20-, but Sophie's mother and Stephanie's oldest sister, Makayla, used to ask her to spend some time with her when Sophie was left alone, since she wasn't too mature and used to take some parties whenever she had the chance.

Taking care of a grown-up brat wasn't the best plan for Stephanie to spend a Saturday night, but her sister paid well, and knew that Stephanie needed the money.

Makayla Kanto was a profitable businesswoman that had made a little fortune by selling a new brand of rope known for its tightness. That meant she had no problem in offering her little sister an also little fortune for each time she cared for her beloved daughter.

"Have fun, girls" Makayla said. "And please, Sophie, behave and be good with your aunt".

"Don't worry, mum. We'll be fine" the little redhead replied.

"Sure" Stephanie added, boring.

Makayla shut the door behind her, leaving the two women alone.

Sophie was a beauty indeed. Redhead with green eyes, short but with nice curves and a sweet, pale skin. Stephanie wasn't ugly either. Black hair, black eyes, about 5'4. She was really shy, meaning she had never been interested in parties or hanging out, unlike her niece.

"I'm planning on having some friends over tonight, are you okay with that, Steph?" Sophie asked, anticipating her aunt's reply.

"Of course not. That's exactly the kind of things your mother has me here for. To prevent you from having any parties".

"Oh, shit. We're almost the same age, when did you become such a boring adult?"

Stephanie didn't reply this time. She had no intention to have an argument that day. So Sophie just headed upstairs angrily and left her aunt in the living room. She laid down on the couch and just left the time pass.

She woke up to a gloved hand landed over her mouth. As she opened her eyes, they faced a masked yet female face.

"Don't make a sound" a soft voice spoke up.

Stephanie looked at the other hand of the newcomer. She was carrying a gun, pointing at her.

“Now I’m gonna take the hand off your mouth, but you know what’ll happen if you scream, right?”

Stephanie nodded, so the burglar did as she had said.

“Please don’t hurt me” begged the babysitter.

“I won’t, but only if you behave”.

“I will” said the brunette.

“Now why don’t do something for me and call little Sophie? And don’t try any trick”.

Steph gulped and complied.

“Sophie! Can you come to the living room for a moment?”

She heard some protests that soon became steps approaching.

As soon as Sophie stepped inside the living room, the redhead froze at what she saw. A ski masked woman was pointing her aunt with a gun.

“Well, Sophie. So glad you could join us. Can you sit on the couch, please?”

Sophie, unable to utter a single word, just nodded and obeyed.

“You, what’s your name?”

“Stephanie” the sitter managed to reply.

“And what are you doing here?”

“I’m… I’m Sophie’s aunt, and I’m here to take care of her”.

“Well you’re not doing very well, are you? Hahahaha” the robber teased. “Anyhow, here’s what we’re going to do. I’m going to stay here with dear Sophie and you’ll go find some ropes from the Queen of Ropes, Makayla Kanto. Don’t hesitate in bringing as much rope as you can carry. Don’t worry, I’ll take good care of your beautiful niece”.

“Please…” begged Sophie. “Please, Steph, do as she says”.

“Yes, Steph, listen to you niece”.

Stephanie complied and got to the garage, where her sister kept the new material that hadn’t arrived to the stores yet. She came back to the living room with several coils of rope.

“Fine, let’s get started then. Steph, be a dear and strip Sophie to her bra and panties”

“WHAT?” Stephanie replied, scared.

“Any comments?” the robber asked while holding the gun up, pointing her head.

“No… I just… okay” she agreed, defeated.

Steph began stripping Sophie, before the redhead’s eyes of disbelief. She was wearing a black tube skirt and a red tank-top. She also wore a couple of red high heels that Steph couldn’t believe were comfortable to wear at home.

She began undressing her niece, by taking her heels off. Next, she helped her take off the tank- top and lastly her skirt. She was half naked, her young beautiful body just covered by a red bra and a black pair of panties.

“Okay, nice body by the way. Now tie her up” the robber said as she handed Steph a coil of rope.

“But...”

“Oh, come on. And better do it tight”.

Steph helped her niece’s wrists behind her back. Sophie couldn’t say a word, she was petrified at the situation. To the robber’s surprise, Steph did a pretty good job on her wrists.

“Now, do her elbows. And make them touch! I’m sure this pretty thing is flexible”.

Aware that trying to protest would only lead to another threaten, Steph just forced Sophie’s elbows together before wrapping the rope around them.

Following the robber’s orders, she soon had her niece’s full body covered in ropes: ankles, calves, knees, thighs, wrists and elbows were tightly secured so Sophie wouldn’t be able to escape.

“Nice, very nice. How do you feel, Sophie?”

“It’s tight” the girl protested.

“Well, I’m so not sorry, hahaha” she mocked.

She then searched inside the bagpack she had brought and got a rubber ball attached to some kind of strap.

“I don’t think you’ve ever seen something like this, girls, but this is called a ballgag. And Steph, you’re going to use it in Sophie’s mouth”.

“WHAT?” Sophie protested.

“Are you protesting?” the burglar teased the girl as she pointed her with the gun this time.

“No, ma’am” she said lowering her face.

“I thought so. Steph, move on”.

Stephanie obeyed as she strapped the ballgag inside Sophie’s mouth.

“Mphhhh mphhh” the redhead attempted to say through her gag.

“See how that works? Pure magic”.

Stephanie looked away as her niece protested and squirmed against her ropes. She knew she was next.

“Steph, I’m afraid it’s your turn”.

“So… what do I have to do?”

“Don’t play stupid with me, hun. Strip down to your underwear”.

She mumbled a slight protest that ended before it even started. She began by taking off her tight leather jeans and followed her long-sleeved shirt.

All that was left was a pink Hello Kitty pair of panties and double D white bra. Steph wanted to die of embarrassment. She had never felt so humiliated in her whole life.

“Now put your hands behind your back”.

Stephanie obeyed and the burglar began with her bindings. She was bound even more strictly than her niece. Apart from tying her elbows, wrists, thighs, calves, knees and ankles together, the robber had also added some more ropes. One for her feet, another for her stomach, that had been attached to her bound hands, and another one for her breasts, framing them.

“Now I want you to lay on your stomach” the robber ordered.

“How?”

“Just roll over, hun. You can do it”.

Steph complied and soon her stomach was touching the carpet on the floor. She felt how her ankles were pushed towards her butt and saw her captor to take another piece of rope.

“What… what are you doing? Don’t you think I’m tied enough?”

“I’m just making sure you’re not going anywhere, dear. This is called a hogtie” she replied as she tightened the knot binding her ankles to her elbows.

“Ouch! That hurt!”

“Oh, sorry, did you expect a burglar to be careful with you?” she mocked.

“I guess you’re going to gag me now, right?”

“Oh, you think well, but I’ve got a little surprise for you” she disappeared, leaving the two young women alone.

“Don’t worry, Sophie. I’ll get us out. No matter how”.

“MPHhhhhh” Sophie said back.

The masked woman came back holding something in her hands. When Stephanie realized what that was, she began shaking her head.

“Oh, no, no. You’re not going to stuff those in my mouth!”.

‘Those’ were two pairs of panties from her sister and niece, one of each.

“I don’t think you have a word here, lady”.

“But I have cooperated! I’ve been nicpmhhpphhhhhhhhh!” she couldn’t finish her last line, since Mrs Robber stuffed the used panties inside her mouth.

“Oh, sorry, I thought you had finished talking” she mocked again as she stuffed the ballgag back in her mouth.

“MPHHHHHHHHHHHHHHHHHHHHHHH” Steph protested.

“Now I’m sorry to leave you girls, but I have some job to do” she stood up and moved upstairs, but first, she took Steph’s purse. “I’m taking this, you know? One can’t know how much is gonna find, hehe”.

‘Fucking greedy bitch’ thought Stephanie. ‘She has a whole mansion to rob and still needs to take my purse!’

“MPHHHHHHHHHHHHHHHHH” Steph protested as she began rolling on the floor.

“Mphhhhhhh” Sophie’s soft protests could barely be heard by Steph. What was wrong with her? Didn’t she want to be freed?

Steph kept screaming through her mouth and wriggling and struggling against her bindings. She tried to make a sign for Sophie to lay down and helped her, but her niece didn’t seem to understand.

“Well, ladies, it’s been a pleasure, but I’m afraid I must go. See you!” said the woman as she left the place.

“MPHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!!”

Stephanie wriggled against her bindings, but the hogtie she was bound in allowed her to do little to escape her predicament. The more she tried to move, to more the rope dug into her skin. It felt so frustrating.

Stephanie knew that if she managed to undo the knot binding her ankles to her elbows, she might have a chance to stand up and hop to get some help.

What she couldn't stand was Sophie not trying to do anythng. She was barely bound compared to her, and still didn't move. She was sitting on the couch and didn't help her or tried to get out on her own.

Stephanie grunted at her, trying to catch her attention and have her down on the floor to help her. But the girl didn't move an inch, she just stayed there, tied, gagged and immobile.

"MPHHHHHHHHHHH" Steph yelled at her niece.

"Mphh mph" were the soft moans that the redhead offered as an answer.

Realizing her niece wasn't going to be of any help, Steph just kept wriggling and struggling against her own bindings, doing her best to try and untie her hogtie. But it was to no avail. The ropes dug into her skin tightly, hurting her and preventing any attempt of becoming successful. She had to admit it, her sister had a really good product to sell.

Her best choice would be to roll over and find something to try to cut the knots. So she tried to move towards the kitchen, giving her niece hateful looks as she just sat on the couch.

When she got to the kitchen, she saw no scissors or knives. At least, not reachable ones. All that effort for nothing! She grunted furiously.

“MPHHHHHHHHHHHHHH” she yelled, but no one could hear her.

She began to squirm back to the living room when she heard the front door opening. Was her sister back? Or was it the robber?

She reached the room and saw a woman standing before them. She knew her well. It was Alex, Makayla and Sophie’s neighbor.

“MPHHHHHHHHH” she tried to call for help, but, as usual, all that came out were muffled useless attempts.

She noticed that Sophie was apparently smiling behind her gag, and so was Alex.

“Wow, it seems we have a situation here, don’t we, Steph?” the newcomer asked, mock in her tone.

“Mphhhh?”

Alex was a stunning redhead woman in her mid-20s that was really close with Sophie. That could only mean trouble.

“Okay. Confession time, does this seem familiar to you?” she asked as she took a black ski mask and covered her face with it. “Don’t move!” she mocked as she took the fake gun she had used against them before.

Now it all made sense. Sophie not trying to get out, the fact that she had been bound and gagged in a much more strict way than her niece. But why the stuffing? Why the humiliation? What did they wanted?

“Sophie told me how boring you were, never letting her to have any parties or anything, so we both agreed to play a little roleplay to keep you away from this house for a while. I’ve called Makayla and told her there was something strange going on in her house. Just wait until I tell her how her little sister tried to rob her house and tied her daughter to do it!”

“MPHHHHHHHHHHHHHHHHH!!!” Steph protested.

“MPhhhh mphhhhhh” Sophie laughed behind her gag.

“And if you think she won’t believe us, wait until she sees the content of her safe emptied inside your purse, apart from a couple of tickets for England, hehehe”.

Steph couldn’t believe her ears. So Sophie had tricked her into the whole thing just for not letting her have any party? For real?

“Makayla will be so mad at you she won’t even want to take off your gag, you want to bet?”

The brunette shook her head. She couldn’t believe her sister would be so stupid. She would want to contrast their versions.

“Oh, she’s here, I better untie you, Sophie”.

Alex undid Sophie’s gag before Makayla entered the house, and kept untying her as the came in.

“WHAT IS GOING ON HERE?” she screamed.

“Oh, I can explain, mum. It’s been terrible!” Sophie said, while Steph kept protesting and moaning through her gag. “Stephanie has overpowered me, tie me up and gag me and torture me until I told her your safe’s combination!”

“Is that right, Alex?”

“Yes, I called you because I felt something was not good and indeed it was. When I came in, I saw Stephanie searching inside your safe, while Sophie was bound and gagged on the floor”.

“MPHHHHHHHHHHHHHHHHHHHHHHHHH!”

Stephanie was waiting for her sister to take her gag off but, apparently, she had no intention to do so.

“Is that what happened, Steph?”

The brunette shook her head ‘no’, but it was useless for her sister.

“I think I should take her gag off to hear her version”.

“She’s full of crap, mum. Just check her purse!” Sophie pleaded.

Alex handed Makayla Stephanie’s purse and the home owner opened it.

Inside it, she could find tones of cash and a pair of tickets for England. But it wasn’t the whole thing. The woman also took a giant roll of a white tape.

“So you didn’t have enough with robbing me and binding and gagging my daughter, Steph. You also wanted to take my last invention??? Gosh, I knew you needed money, but you could have asked me, not rob me!” Makayla was angry, and Steph knew she had no longer intention to ungag her.

“MPHHHHHHHHHHHHHHHHH” she tried to explain herself uselessly.

“What is that, mum?” Sophie asked.

“It’s a new kind of tape that isn’t only more sticky than the usual ones, but it also muffle sounds, so you can use it on pipes, or…” she grinned as she left the sentence unfinished. “Okay, Steph, I’ll offer you a deal. I won’t call the police on you if you let me do a live test on my last invention. How does that sound?”

So the bitch of her sister was just as crazy as her daughter and neighbor. Still, defeated and humiliated, Stephanie saw no other choice than to nod and let it all pass.

“Perfect” said Makayla as she peeled the edge of the roll and applied it over the ballgag. “See how it sticks to your skin?”

She began wrapping it around her head, taping her mouth shut and muffling her pleas even more.

“Let’s see, try to yell” Sophie asked, curious.

“MPHHHHHHHHHHHHH” a barely audible grunt escape Steph’s lips.

“Wow, it does work” Alex observed.

“Yes, but… I think that yell wasn’t sincere enough”.

“Mphh?”

Makayla then approached Stephanie’s bare feet and began tickling them.

“MPhahshhahaPPHHHHAAMpHHHHHH!!!!” Stephanie screamed.

“Let me try” Sophie said, and soon took her mother’s place in torturing her aunt.

That was too much for innocent Stephanie. She had been humiliated by her own sister and niece! She had been tricked and the bitch of her oldest sister didn’t even suspect a thing!! She began crying.

“Oh, are you sad? You should have known better before trying to rob me!” Makayla said, angrily. “In fact, you know what? Fuck the deal, I’m calling the cops”.

“MPHHHHHHHHHHHHHHHHHHHHHHHHHHHHH”

“This is too much, Steph. I love you, but I doubt I’ll ever forgive you. And I think you’re a danger to society”.

“MPHHHHHHHHHHHHHH” Stephanie begged through the massive gag keeping her quiet.

“I’m sorry, sis” was Makayla’s last words before calling the police.

Sophie and Alex changed a look of success before her, and Sophie approached her ear when her mother was away.

“I’ll miss you, auntie” she whispered, before kissing her on her gagged lips.
