The Step-Sister

Chapter Ten

“I mean, we just got here,” Harriet pointed out, “Do we have to decide right now?”

“Or maybe Claudia should decide,” Celeste grinned, “Either way, she’s stuck with us, right?”

Claudia was only just able to process the question. So far, the remote control plug had been more of a nuisance than anything else. The fragments of reluctant pleasure had been outweighed by the fact that she was technically in public, albeit just with three girls in her own house. The prudish outfit and her current situation didn’t exactly put her in the most sexy headspace. Still, physical was physical, and the latest vibration pattern Sara had switched to was enough to make this more of a battle of self control.

She still had a reputation to maintain, especially while her current pink and preppy attire was thoroughly undermining her usual image. Steadying herself against the wave of pleasure that threatened to make her eyelids flutter, Claudia steeled herself and put on her classic annoyed look that she often used when Sara’s friends were around. “I really don’t care,” she said. ’Ugh! Managing to keep the groan internal, Claudia immediately checked to see if either of the girls had noticed. Apparently her body had been affected all the way up to her voice, and her words came out faintly weaker than the cold delivery she normally gave so effortlessly.

“So typical,” Sara said. The other girls might not have caught on yet, but Sara had been sisters with Claudia long enough to recognize the more subtle things. It was more about the shift in body language, as well as how obvious it was that the alternative girl was trying to keep her composure with every little curve thrown her way. “You know, girls, Claudia is quite the lesbian slut. In fact, I bet she’d get turned on by her own sister.”

Claudia’s impulse was to flip Sara off, or retort with at least one swear word involved, but she held herself back. The recent reminder about such language had been enough to make her hesitate this time around, as there were definitely some settings on the plug that Sara was saving for her twisted version of behavioral training. Instead, Claudia merely said, “Step-sister. And you were the one ogling my naked body earlier.”

Despite the lack of cursing, Sara sent another effective pulse with the remote. For a moment, it seemed like the timing was related to Claudia’s retort. However, Sara had something completely different in mind. Rather than relenting like before, she pressed the same button again. And again. Stepping just behind Claudia, Sara placed a hand on her shoulder and leaned forward so her lips were inches from her ear. As she did so, Sara smirked and gave a look to her two friends sitting on the sofa. Speaking in a stage whisper, so everyone could hear, she said, “You’re a fucking bitch, Claudia. And a dirty little whore.” With that, she flicked out her tongue to lick her step-sister’s ear, and cranked the plug to its highest setting.

Claudia didn’t realize what Sara was leading up to until it was too late. The toy penetrating her backside was already a lot to handle, as the more intense vibrations were making her knees go weak despite her efforts to keep her body’s urges under control. Unfortunately, bottling everything just made the eventual release that much more obvious when she could no longer keep things sealed.

Her ears were one of her weak spots. There was no way Sara knew that, which made her move a frustratingly lucky guess when paired with everything else. The insulting whispers in an overt and over-exaggerated sultry tone, the unexpected lick, and . . . Claudia wasn’t prepared for the way her sister capped things off, with an aggressive series of vibrations below. It wasn’t enough for an actual climax; she wasn’t that far gone. And yet, Claudia couldn’t stop a breathy moan from escaping her lips. She managed to keep her head from tilting back, and her eyes mostly remained open, but the damage was done nonetheless. Clearly everyone had heard her audible exhale of pleasure, and Claudia actually felt a little damp between her legs as well.

“Oh, my God!” Celeste gasped. Less in judgment, and more in amusement, based on her grin. “Seriously? That’s all it takes for her?!”

“Claudia!” Harriet chastised, although she also failed to stop the trace of a smile from appearing on her face, “What the fuck? She’s your sister.”

For a moment, Claudia was frozen. So far, she had gone through all of this so coldly and logically. Letting Sara spank her, plug her, and dress her. Letting Sara display her in the living room and explain things from only one point of view. Through all of it, Claudia had bitten her tongue and bided her time. Until this. The plug was literally still vibrating inside her at the high setting, and it wouldn’t be long until something more than a soft moan happened. She couldn’t just stand around and play along, not when Sara was taking things so far while not giving the slightest hint that this would be over any time soon. Without a light at the end of the tunnel, and after this latest turn of events, Claudia was finally coming to her senses.

It would have been better to storm off from the very beginning. Now Sara still had everything from before, plus had succeeded in everything that had followed Claudia stepping into the fully empty bedroom. Sunk cost fallacy only went so far, however. Better to call it quits before she lost even more of her dignity and, more importantly, before she truly lost control in front of Sara and her friends.

“I need to pee!” Claudia blurted out. It was quite unlike her usual brooding demeanor, but she didn’t care. Not waiting for permission, because she was a fucking adult, she abruptly stepped away from Sara and did her best to walk out of the room like a normal girl despite being plugged and turned on.

“Mm hmm,” Celeste taunted, “That’s what you have to do.”

“Come right back,” Sara said. She wasn’t going to attempt to stop her, then. “You’re ours for the night, remember? Until you prove you can be a proper girl, just like us.”

Harriet said something, too, but Claudia was already tuning all of them out. Although the nearest bathroom was just down the hall, she opted for the one up the stairs. Not that she actually planned on going in there. At the moment, her entire plan was to keep moving. The plug’s remote only had so much range, and putting herself farther away from Sara felt more efficient than dealing with the process of removing it while it was still vibrating. Also, how did Sara’s friends not hear anything? While Claudia’s cheeks muffled most of the sounds, it still felt like the hum of the sex toy was so obvious. Then again, she was the one it was being used on, so it could just feel more apparent to her while not being particularly noticeable to anyone else.

Claudia planned on stopping just to retrieve her phone, but she ended up just short of the linen closet. Clasping a hand over her mouth and leaning against the upstairs hallway wall for a moment, she breathed out a longer and more desperate moan than before. Sara had yet to turn the plug down from the high setting she had set it to downstairs, and it was getting to the point where Claudia was wondering if she could just take a minute or two to do what Celeste teasingly implied and get herself off in the solitude she had given herself.

No.

She needed to capitalize on the opportunity before one of the girls came to look for her. Legs still a bit shaky from the constant pleasure, Claudia pressed forward the last few feet to the closet. Her phone was still there. Good. She would have been beyond frustrated if Sara had somehow figured out where Claudia had stashed it.

As painful as it would be to let one of her friends see her like this, Claudia would have to deal. There was probably a way she could spin it as over the top irony, or roleplaying as her stuck-up sister, or something. For the time being, however, she merely stuffed the phone into her bra without giving it so much as a glance. First, she had to sneak out.

Going for her usual route, she next made her way into her bare bedroom and gave the finger to the camera in the upper corner. She opened the window and gripped the sill for a few long seconds as she continued to combat the waves of pleasure coursing through her body. Still in range, then. Swinging one leg over followed by the other, assuming her limbs wouldn’t give out that much once she put herself in escape mode, Claudia climbed out onto the roof and carefully stepped over to the nearby tree after belatedly making sure no neighbors or preppy girls were watching. Taking a huge breath, not loving the idea of doing this while she was turned on, Claudia took a little solace in the thought that the descent would probably mess Sara’s nice clothes a little bit.

It was only two stories, and she could practically make it down blindfolded at this point. Even with shaky legs, it only took twenty seconds or so before her feet were on the ground. Claudia was used to leaving at night, so it was only easier in broad daylight. She let out a quiet sigh of relief. It was still going to be annoying to walk around plugged until she found somewhere private to deal with that, but she’d probably be out of the remote’s range after a few yards.

The momentary victory was ruined, however, when Sara’s voice pierced her thoughts of where to head next before contacting her skater friends from earlier. “You’re so fucking predictable,” Sara scoffed. She was on the stairs of the front porch, already making her way down and towards Claudia. “For real, sis? I know this is what you do like every other night.”

“Screw you, Sara!” Claudia snapped, “I’m leaving.”

“Like hell you are.” Sara narrowed her eyes and didn’t once break her stride as she crossed the edge of the yard. Remote still in hand, she made a show of pressing a button that switched things from the nonstop vibrations to pulses that were equally as assertive. Something to keep Claudia off balance, just as she had gotten used to the former variety. “I’m not done with you yet. Proper girls don’t climb trees in nice outfits, and they certainly don’t moan in polite company.”

“You’re one to talk . . . ” It was far more difficult to retort when she was still dealing with everything below her waist. Maybe taking it out would have been the better idea after all.

“That’s enough. You’re coming back inside. Right now.”

“And you’re going to make me?”

At that, Sara smirked. “If I have to.”


What does Sara have in mind?

Using Claudia’s handcuffs and locking her wrists together?

Dragging her back inside by her hair?

Or finishing the job that the plug started?
