The Step-Sister
by *Lady Lucia*

Chapter Fifteen

For a few minutes, Claudia had to deal with the awkwardness of being Harriet’s cup-holder. While it wasn’t nearly as degrading as serving as a human footrest, there was still a degree of physical discomfort due to how she had to stay perpetually bent with her arm extended so Harriet could reach the water bottle without sitting up.

Celeste returned shortly afterwards with one of Sara’s purses on her shoulder. “Cool if I borrow this for the day?” she asked, “It matches my outfit so well.”

“Obviously. You know I don’t mind sharing!” As if to prove it, Sara gestured in Claudia’s direction. Clearly Sara had no issues with her friend going into her room and finding something without asking permission first. Yet another difference between the two step-sisters, as Claudia only allowed people into her bedroom when she was around to supervise them.

“Perf,” Celeste smiled. She returned to her seat, then tossed the accessory over to Sara, “Anything in there you need to take out first?”

“Hmm, let’s see. Harriet, may I borrow our servant?”

“But, who will hold my drink? I was getting so used to being pampered like a princess!”

Despite her teasing complaints, Harriet took the bottle from Claudia one last time and held it herself after taking a sip from it. With a dramatic sigh, of course. When Claudia approached the other side of the sofa, Sara casually demanded a similar service. Instead of placing a drink in her step-sister’s hand, however, Sara directed her to hold her hand out, palm up. Once Claudia was positioned to Sara’s satisfaction, Sara delicately placed her cell phone onto Claudia’s hand.

It was an annoyingly effective test of obedience. Destroying the phone was an immediate temptation, until Claudia realized it wouldn’t actually solve anything. Sara was smart. Whatever digital leverage she had on Claudia wouldn’t be limited to her smart device, plus that was hardly the extent of the problem. Sara still had all the damning physical items from Claudia’s room, and she could easily call their parents from one of her friends’ phones. That’s what made the current task so frustrating. Even holding something so personal of Sara’s didn’t come remotely close to solving Claudia’s problems, which meant all she could do was allow the phone to rest on her palm.

The arrival of Sara’s purse sparked a conversation about fashion with the seated trio. They chatted with each other, completely ignoring Claudia as if she really was just a piece of furniture in the living room. It was better than being the center of attention like she was earlier, yet also all kinds of rude and insulting when her time would be better spent hanging out with her own friends like she was supposed to be doing tonight.

“Okay, Claudia,” Sara said. Addressing her sister after a few minutes of not acknowledging her in the slightest, she said, “Close your eyes.” Punctuating the command with another single pulse of the plug, which she seemed to have settled on as a way to remind her sister to behave, Sara followed up with, “And open your mouth.”

It was painfully suggestive, especially coming from someone who lived under the same roof as her. Before Claudia could voice her distaste, Harriet held up a finger and echoed her phrase from earlier, “No more talking, Claudia.”

Claudia briefly frowned in annoyance, but reluctantly did as she was told. Closing her eyes and subjecting herself to the unknown that came with losing her vision in front of the three girls who all seemed to enjoy this preppy, obedient version of herself, Claudia slightly parted her lips as well. What was Sara planning? It couldn’t be another picture, as something like this wasn’t nearly as damning as some of the other images and videos from earlier. Maybe they were going to make her eat or drink something spicy or gross.

At least one of the girls was getting up. Claudia’s eyes naturally twitched in curiosity and self preservation, until Celeste firmly reminded her to keep them closed. On top of that, she said, “Wider, Clauds. Show us what a slut can do with her mouth!”

Not nearly as subtle as the suggestive nature of the initial command. The plug vibrated when Claudia didn’t immediately listen, causing her to flush and begrudgingly open her mouth as wide as it could go without being painful.

As soon as she did, a ball gag was roughly being shoved into her mouth. “Mmm!” It was not at all what Claudia was expecting, and her eyes flew open in surprise. Before she knew it, the leather was being tightly clasped on the back of her head.

“Much better,” Sara said into her ear, “Hold still, sis. You don’t want your hair to be caught, do you?” With that, she went about pulling Claudia’s locks up until her hair was mostly covering the back of the black leather strap. “Perfect. How does she look, girls?”

Claudia’s peripherals weren’t enough to see any defining features of the ball gag, but she was almost certain it was the one that she owned. Unlike most of her toys, this was one she had never experimented with on herself. Still, the silicone in her mouth matched the material of hers, and she doubted Sara would have something like this lying around. It had to be from the collection Sara confiscated from Claudia’s room.

“Hot!” Celeste grinned, “And perfect for a servant girl. It’s not like she has to talk to do her job, right?”

“Exactly,” Sara giggled. She switched the butt plug back on, setting it to a slow but persistent vibration, “Do you like your accessory, Claudia?”

Cheeks flushing, Claudia hurriedly nodded her head. Anything to keep Sara from ramping up things again where Claudia’s backside was involved. The gagged girl had only just recently come down from all the earlier sensations and lesbian activity.

Sara went on. “And you like your makeover? You think my clothes are better than yours?”

Any chances of denying that concept evaporated when the vibrations increased in speed and intensity. Once again, she desperately gave a nod.

“That’s what I thought,” Sara said, “Okay, sis. I think it’s time for you to do something your old self never would have done. Give me your hand.”

Claudia reluctantly held hands with her sister, despite the fact that their usual dynamic was the complete opposite of touchy-feely. Apparently the act of doing so wasn’t what Sara was referencing. Hand in hand with her step-sister, Claudia was walked to the kitchen. The other girls followed when they saw that Sara was leaving the living room, no doubt curious what their friend had in mind.

Their destination was a lot less dramatic than Claudia anticipated. She was merely walked over to the kitchen table and told to sit down. It was nice to have her hand liberated so soon, although sitting down on the hard wooden chair with the plug still in her ass made her wince and shift in the seat. The kinky toy pushed itself a little farther up, bringing on a reluctant wave of both pain and pleasure due to how there wasn’t a trace of lube back there to soften things.

“Sit right there, Claudia. Don’t move a muscle.” Sara turned to the other two and said, “Keep an eye on her?”

There wasn’t much Claudia could do in the meantime. Even if she wanted to remove the ball gag, it wouldn’t go over well when she was still outnumbered and supposed to be perpetually obedient and subservient. Still trying to keep some degree of dignity, she didn’t attempt to make a single sound. It would just come across as whiny and muffled, as she had experienced from the dominant side of things before.

Celeste and Harriet didn’t feel the need to overly supervise her. They made themselves comfortable around the kitchen’s island and continued their conversation about shopping, eventually showing each other links to various outfits on their phones. Claudia wasn’t actively trying to listen, but there wasn’t much else to do when she was stuck sitting in the otherwise quiet and resonant kitchen. It was so much worse than overhearing their girly conversations down the hall; even then, she was only subjected to that for as long as it took her to close her door and put on headphones.

“Back! Miss me?” It was unclear whether Sara was talking to her sister or to her friends. She was carrying an enormous stack of textbooks and binders, all of which she dropped onto the table with a heavy thud. With little warning, she bent over and gave Claudia a peck on the cheek. “Okay, girls. Get ready to witness something monumental.” She stepped back and gestured to Claudia and the haphazard pile she had placed in front of her. “Claudia is going to do schoolwork . . . on a Friday!”

Her two friends dramatically gasped in unison. It made Sara’s underwhelming reveal that much more annoying to Claudia, and also drove home how in sync the three girls were. There was no way they had planned that together ahead of time.

“But actually, sis,” Sara said. Turning her attention to Claudia, she said, “I want you to take out your syllabi and find all your assignments that are due on Monday. Oh, and don’t drag your feet. I will spank you in front of my friends if I have to. Hop to it, Clauds!”

There wasn’t much else Claudia could do. As Sara sauntered over to the island, Claudia opened the first binder and started leafing through the disorganized stack of papers in the front pocket to find the semester’s schedule for her history class. She couldn’t remember the last time she referenced the syllabus, since most of her teachers regularly made the weekly assignments available in other forms.

Just when she was working on the last binder, trying as always to tune out the preppy voices across the room, the familiar sound of their doorbell echoed through the house.

“Ooh, I’ll get it!” Sara exclaimed, “Claudia, stay. And behave.”
