Chapter 4 Remote Control: A Tantalizing Discovery(4)

• "Got it." Before anyone could say anything else I hopped to my feet. "I'm gonna go ahead, see you in the car." The last thing I wanted right now was to have a moment alone with Elayne, without our parents around to prevent her from bringing up whatever the fuck was going on. Before stepping into the garage, I did fish the remote out of my pocket, though, noting that only a single light was on before pushing it back into my pocket. When I'd turned it off it had still been on the second setting, so it seemed like it had reset from being powered down. It wasn't information I really needed to know, but I supposed I was learning more about my sister's toy the more I used it.
• An added advantage to arriving first was that I could take the front seat which meant there wouldn't be a chance for Elayne to sit in the back with me, as well as giving me the chance to be able to still see her in the mirrors. I realized that on the way to the garage, I'd already made up my mind to keep messing with her. If she was going to stick a vibrator up her pussy, knowing that I still had control, then that was on her, not me. That was how I justified it, at least.
• The car was already pleasantly warm as I took my seat and fastened my seatbelt, my dad giving me a welcoming grunt as I joined him. It was only a moment later before Elayne stepped into the garage and, of course, my eyes were pulled to her like a magnet.
• Like me, she was wearing a hoodie so I couldn't fully tell what kind of shirt she was wearing, but the zipper was slightly down, giving a peek at her collarbones. Fuck. Other girls had attractive-looking necks that I wouldn't mind kissing, not my sister. I had to get it together. Below it, she was wearing a skirt that stopped a few inches before her knees, accompanied by black tights thanks to the cold weather. They only enhanced her long legs, though, which I firmly jerked my eyes away from. I was not going to start lusting over my sister, as much as my cock clearly wanted me to. Part of me whispered that fucking her with a vibrator was a very dangerous step away from that, but I blocked it out.
• "Let's go," she sighed as she slid into the back seat, closing the door and clicking her seatbelt into place. I wasn't entirely sure but I was pretty sure I felt her knee jab into the back of my seat.
• Dad was, thankfully, like me, less into conversation, so it wasn't strange at all for our morning drives to pass in silence, outside of whatever song was playing on the radio. I waited a few blocks before setting my plan into motion, carefully getting my hand into position over my pocket in a way that wouldn't draw any attention. Once I was ready, I hit the plus button, increasing the vibrator to its second setting.
• There was every possibility Elayne had found a moment to slip the vibe out before joining us in the car. It's what would have made the most sense, to me at least, so for the second time in one day, I was absolutely floored as a soft whimper floated out from the back seat. She was seriously wearing it to school. No. Fucking. Way. I was starting to wonder if I'd somehow woken up in an alternate reality, where up was down and nothing made any sense anymore.
• "Everything okay back there?" my dad called back, glancing into the rearview mirror but still keeping his eyes on the road.
• It was a moment before my sister responded. "Yeah. Might have had one too many waffles. Don't worry."
• I struggled not to snort in amusement. My dad would probably buy it since there was no way he could imagine his little angel getting off in the backseat, but there was no way that sound had been an overly full stomach. Too many waffles my ass.
• I left her on two for several more blocks, doing my best not to think about what was happening in the back seat, even though my ears were fully at attention, straining for even the slightest noises that Elayne might make. And she was making noise, although it was incredibly hard to hear over the music. There was no way our father would catch it, but it was having a noticeable effect on the limited amount of room in the crotch of my pants while I was sitting down. I had to struggle to shift around in the seat to try and readjust into a comfortable position without cluing in either of them to my predicament.
• We finally reached the road construction that was along the way before much longer and I set the second part of my plan into motion. The road here was in pretty bad shape and they'd closed off one lane in each direction to fix at a time. They were nearly finished, but there was still another week to go, meaning we'd have a bumpy ride for the next few miles. It was the perfect excuse for some less-than-normal noises from the backseat.
• I almost felt bad as I pressed the plus button once more, bringing the vibe up to its third setting, but Elayne was the one who'd put herself in this situation. I'd be an idiot not to take advantage of it. Or, at least, that was how I explained it to myself.
• The first moan that came from the back nearly caused me to lose it. I became so caught up in the uncomfortably hot noises my sister was making that it took me a while to notice just how clever she was being. Each of the louder, easier-to-hear moans was carefully timed to line up with moments when the car jolted from the condition of the road--allowing her to disguise them as a groan. It was honestly impressive, and I would have congratulated her if I'd been capable of anything other than concentrating on desperately trying not to cream my pants. Every hidden moan from her sent another surge racing through my cock, and it wasn't long before I began to wonder if I was the one torturing her or if it was actually the other way around.
• I snuck a look at the side mirror and was rewarded with the sight of Elayne's cheeks flushed an undeniable red. She was feeling it too alright. God, she looked so fucking hot. I didn't even feel too bad when the image of her playing with her nipples filtered back to the forefront of my thoughts. Without thinking I pressed the plus on the remote again, bringing it up higher than I ever had before.
• "Fuck!" Elayne shouted, her eyes bulging. I quickly jerked my eyes away from the mirror, but not before I felt us make the briefest moment of eye contact.
• Luckily for her, we'd happened to hit a pothole at the exact same moment, giving her the perfect out. "Sorry, I'm sorry," my dad called out, "That's a new one. All good?"
• "No!" she snapped back, clearly breathing heavily. "That's too much, scale it down a notch, please."
• The car slowed down a bit, but I knew that wasn't what she was talking about. Guilt tying my stomach in a knot, I quickly hit the minus button on the remote, dropping her back down to the third setting. I probably should have gone lower, but I stopped there. If she wanted it lower, Elayne gave no indication, the soft moans now fully back in all their glory.
• As we neared the end of the construction, I moved to once again lower the setting on the vibrator, only to notice that her noises from the back had completely stopped. Was she... trying to show me that there was no need to drop it? I felt like it had to be me assuming things, so I snuck another quick look at the mirror to try and see what kind of shape she was in.
• It was a mistake. Her eyes immediately locked onto mine, boring into me. I swallowed, unable to pull away from her gaze. Did she expect me to say something? Do something? This was the first time we'd ever actively acknowledged what I was doing to her, and even if she was just looking at me and not saying anything I felt myself withering. I'd fucked up. Badly.
