Setting the bait

The profile you loaded up was Lucy’s and with the panties you had now recently used as bait, you planned to get her at the worst possible time.

Activating ‘Underwear thief’

You waited with your ear pressed against the door to the bathroom and listened out for any signs of movement in the corridor. Hearing a door open up out there, you waited until the sound of footsteps got quieter as they presumably headed to your room and used this time to strike. You wrapped your towel around yourself and left the bathroom before creeping down the hallway. The sounds of movement were definitely coming from your room and although you couldn’t see anyone from the open door you took it as a sign that it was indeed Lucy routing around in there.

Instead of going in to confront her, you slowed down even more, reaching the door to your room without being seen and watched as Lucy came into view. You had kept the panties near your pillow until you could think of a better spot to keep them but now you grinned at the sight in front of you.

Lucy had almost certainly narrowed down her search as she was bent over your bed with her upper half-hidden under your covers. Her ass was perfected pointed towards you at the door and with her head facing away from you, you had the time to stare at her without getting caught. It also explained why she hadn’t heard you creeping up on her so you felt confident enough to walk further into the room.

You took a couple of steps in and pushed the door behind you, not completely shut but far enough to obscure the vision of anyone else who wanted a peek inside. Lucy seemed to suddenly stop moving when her hand seemed to be near your pillow and she slowly pulled herself back and straightened up. She still had her back to you but the balled up underwear in her hand was enough evidence you needed to confront her.

“Find what you were looking for?” you announced, making her jump at the sudden noise.

She turned around to look at you and deflated once she realised you had seen the underwear clearly in her hand. She opened and closed her mouth a few times, trying to find the right words to get her out of this situation but she seemingly gave up when nothing came to mind.

“Fine alright, you got me. What do you want?” she patronisingly asked, keeping her arms crossed and still acting like you were somehow in the wrong.

There were plenty of things you slowly wanted to add to the deal and although you'd probably have to let her get away with stealing the panties once in a while to not raise too much suspicion, you could probably get away with using the active once or twice a day thanks to the 12-hour cooldown.

As much as you did want to up the ante with Lucy, you decided now would be a good time to get her to agree to something more long term.

“With it being the first time your being punished, I’ll let you off on changing anything with our deal” you said, seeing Lucy’s eyes light up before you carried on. “But, and this is a big but, I want you to promise me something for later.”

“How is that any better from just adding something to the deal?” Lucy asked skeptically, trying to figure out what you were trying to accomplish.

“Don’t worry it's nothing too bad I promise. It’s just that when Dad leaves, presumably after this weekend, I’m planning on getting everyone together for a family meeting and I want you to back me up on whatever I propose” you explained, not giving away any details of what you are actually planning to put forward.

Lucy still stared at you with questioning eyes but eventually, she seemed to loosen up to the idea.

“I still don’t trust you but... fine. I can’t be any worse than whatever you could change with the deal...Can it?” she asked after a pause.

“No it isn’t. Well I don't think it is anyway, I’m sure Mom might disagree but hopefully you and Sarah will see the benefit in it” you replied, leaving Lucy just as confused as she was before, if not more so.

“So, is that a promise?” you asked, holding out your hand so that the both of you could shake on it. Lucy grumbled to herself as she stared at your hand but she eventually gave in, forcing her to use the hand that wasn’t holding her panties.

“Fine I promise, Now if you’ll excuse me I need a shower before Mom starts complaining” she announced, about to head to the door with the underwear clearly still in her hand.

She was about to exit the room when she stopped and turned around, it seemed that something had just popped into her mind but she looked a bit nervous to say what it was. You didn’t try and interrupt her and she seemed to pluck up the courage when she saw that you were waiting for her to speak.

“By the way… when did you and Sarah leave last night. I remember waking up and the two of you were gone. “She asked, filling you with a sense of dread at how you had left her last night.

“... We got out of your room a little after the movie ended. Both you and Sarah were already asleep when it ended so I had to drag Sarah out of there to try and not wake you up. We didn’t wake you, did we?” you asked back.

“No no, it's just… I can’t believe I fell asleep during a movie. It makes me sound like an old man” she joked.

You weren’t sure if that was what she really wanted to say or if she was just changing the topic to hide her embarrassment. In either case, you didn’t plan on questioning her so you **** the topic away from anything remotely close. You still had your towel wrapped around your waist but in an attempt to surprise her, you let it fall to the floor and started to get changed as you carried on talking

“Speaking of Sarah, I should probably go wake her up soon. There's no use getting ready on time if she just stays in bed but I’d use the shower while you have the chance if I were you.” you replied, turning to look in Lucy’s direction to see her shocked expression as she stared at your naked body.

Talking to her seemed to snap her out of her daze and she sheepishly left your room as you continued getting changed. Your outfit was similar to yesterday as smart casual seemed to be enough for Mom to deem worthy for you to leave the house. It didn’t take long for you to get yourself presentable and you exited your room and went towards Sarah’s.

Considering the state you had left her in last night, you made sure Lucy was no longer in the hallway before sneaking your way into Sarah’s room. You could have knocked or just used one of her actives from the KDK to wake her up but you weren't going to miss a chance to have a little extra fun.

The room was dark but the smell of sex still permeated the room, filling you with an unexpected giddiness. Sarah must have shut her curtains after you left, leaving you to fumble around in the relatively dark room until your eyes adjusted. Once they did, your eyes widened in surprise as you got a clear look at your sister. She looked exactly the same as how you had left her, lying on top of her covers with the only difference being a small bullet-shaped device just out of reach from her hand.

You instantly knew that it was a vibrator but you had no idea how she had even managed to keep that hidden under Mom’s all-seeing gaze but knowing that it existed gave you plenty of ideas for the future. You guessed that Sarah had continued playing with herself after you left and either passed out from the pleasure or just never found the need to make herself presentable.
