David's Next Game

About a week after she started investigating, Diana was given news which threw her for a loop. According to David, Lisa had been feeling ''rather poorly'' so he was going to let her return to her old home for a few days to rest and recover. Having to stand there, next to the guy in the college office while Lisa stood naked behind him, her gaze turned towards the ground, was one of the harder things that Diana had ever had to do. Much less thank him for it!

Nonetheless, Diana agreed with the proposal, though not without a certain amount of suspicion. She knew that David wasn't the sort to really care about Lisa like that. It was obvious that this was some sort of scheme or trap on his part, and she had to be careful not to fall into it. Interacting with her sister during college hours was dangerous, but she shouldn't be in danger if she did it after them. Maybe David was hoping that she'd slip up and talk to her sister during the day as well? or use her name in college? Diana was absolutely confident that this was some plan to get her enslaved as well, and probably, it would have been smarter not to even buy into it.

...but that would have meant sending Lisa away, rather than giving her a sanctuary from the torment, which was a factor that both Diana and David knew she would not be able to resist.

That was why, in spite of her doubts and worries, Diana accepted the offer, and several days after this, there was a knock on the door of their apartment. Diana didn't know what to say or do when she opened the door, and saw Lisa standing on the other side. Her younger sister was flushing bright red, and looking towards the floor. Diana knew why instantly. David had put a band around her inner thigh, and a wire stretched from a control strapped there to a machine in her pussy. Her lower lips were parted and wet, and she was trying to fight against the urge to cross her legs and hide the evidence. She was still wearing her collar, and would continue to wear it for her entire time at the house, for this had been one of the requirements for it even to be considered at all. She had a bag slung over her shoulder, but other than this, was totally naked.

"H-hi sis..." Lisa said. "Um...can I come in? It's uh...just that David made me walk around the area a bit and I came a few times because of this stupid machine..."

She was blushing as she admitted this, even though Diana could easily see the evidence between her legs.

"And I'm sort of really sensitive down there, and I'd just like to sit down..."

Diana let her inside instantly, without another word. her heart was beating fast, and she was filled with anger at the state of her sister. Lisa moved slowly, trying to keep the vibrator inside of her pussy at all times. Diana could hear the faint buzz as her sister walked past, and she wondered for a moment what it must feel like to walk naked, with such an obvious tool of pleasure teasing you relentlessly. Would people stop and stare at you? Would they see how helpless you were, how aroused you felt? Would they see the trickle of liquid staining your inner thighs as the vibrator went on and on and on, teasing you and tormenting you until you wanted to scream?

She shook her head, dislodging the thoughts before they could form properly. This wasn't the type to let her fetish get in the way of things! She had a job to do as an older sister.

The door closed behind them, and Lisa let out a long, low sigh, the tension seemed to flee her body, and she collapsed on the chair, raising one hand to support her forehead for a moment. She looked so tired, so utterly exhausted. Then, she looked up again, catching Diana's eye.

"Well, I think we can say that this has gotten a bit out of control." She managed a grin, though it didn't quite reach her eyes.

"A little bit..." Diana admitted, sitting down on the opposite chair. For a moment, she didn't know what to say. She tried to find the words, but they fled from her tongue. She grasped blindly, hoping to find something that she could verbalise.

"I'm...I'm trying to fix it." She said, "But it looks like someone else also has a rulebook, and they're not letting me just write this whole thing away. I...I already erased the rule about you and Stacy, but neither of you were freed..."

"I see..." Lisa said, trying to focus, though it was clear that the vibrator between her thighs wasn't going to let her do that without a fight. She was soaking down there, and every now and then, she jerked, or twitched as her body reached a new level of pleasure. "Well at least that's better than thinking you were just abandoning me to my fate."

She grinned as she said this, but even so, Diana felt moved to ask, "Did you really think I'd do that?"

"Well, some would probably say that I deserved it, seeing as how I set this whole thing into motion..." Lisa closed her eyes briefly, a shiver running through her body. "F-fuck. S-sorry, Diana. This thing has been in me all day and I'm not allowed to take it out. It's got a battery to last a week, and that bastard, sorry, my _charming _master, made sure to tell me that if I took it out, I'd be punished even more severely. But no, I never thought you would just abandon me. What are we going to do now?"

"We're not going to give up." Diana rose to her feet, pacing back and forth as she stated her thoughts. "I have a plan in motion to try and track down the other rulebook. Once I have it, I can erase the rule there too, and make it so you and Stacy are both freed. In the meantime..."

She bit her lower lip, looking back on her sister with an apologetic gaze.

"In the meantime, I can't really help you directly, Lisa... I...I'm sorry, I really am... if I could I would, every time I see you paraded through the halls I hate it! But if I did something and it was seen, then..."

"You'd get enslaved too." Lisa nodded, "and then there's be no one to help us both. Yeah, I get it. I fucking hate it, but I get it." For a moment, her face looked so ****, her whole body did, siting naked on the chair, with nothing to protect her dignity, or shield her nudity. Diana felt fury boiling up inside of herself again, but wrestled it down, relying on her strength of will and intelligence now was the only thing that she could do. The only chance the two of them had.

"How long can you stay here?" Diana asked the question which had been foremost in her mind. David had never specified the amount of time that Lisa would remain at home, but Diana didn't think it would be particularly long. Since David was clearly enjoying his power greatly, the only reason he would let her go home was to remind her of what her life had been like before. That only required a day or so, though Diana was desperately hoping that Lisa would have longer.

"Just a day..." Lisa said, her eyes going to the ground. "David said that he wanted me to see how far I'd fallen. But..."

She trailed off, her voice breaking for a moment as she looked back up at her sister.

"He said that he would give me a week if we both did what he wanted..."

"I guessed as much." Diana growled. Her fists balled, and she stalked the room for a moment before turning again.

"All right, what does he want from us?"
