Family Road Trip Ch. 03

"What should we try next?" Karen asked playfully. The question echoed playfully within my head unleashing a slew of deviant desires that I'd never before dreamt possible. Unfortunately before my racing mind could settle upon a properly perverse plan for what to do next I felt the car begin to slow as Dad pulled off the highway.

Karen silently slipped her tongue into my mouth for one more kiss before climbing over the seat into the pile of pillows and blankets in search of her formerly forsaken top. Shifting my gaze out the window I realized we were pulling into a highway rest area. Just as Dad eased into park, Karen maneuvered her now fully clothed body back over the seat and settled herself next to me.

Unable to follow as Karen and my parents exited the car I remained stuck, contentedly, under Sarah's slender legs as she slumbered on. It still amazed me that she hadn't woken after all Karen and I had done to her enticingly lithe young body. My Curiosity about the matter was short lived though as Mom poked her head in the open door to say "Oh, Hun you can go ahead and climb out for a stretch. Sarah took a very strong sleeping pill before we left, and won't be up for hours". "Sarah takes sleeping pills...why didn't she say anything?" I asked, trying not to let my excitement show.

"Well she is a little embarrassed that she needs them. You know how she can be. Don't tell her I told you, Ok? I just didn't want you to be stuck in there."

"Sure thing Mom I won't say anything to her" I replied as I slid myself out from under my sister's legs.

Stepping out of the car I lifted my arms overhead to stretch out my muscles. Unable to stifle a yawn after my long stretch I set out in search of the restroom with my mind tangling into knots contemplating all that had happened and all that still could. We spent ten minutes or so at the rest stop before Dad let everyone know it was time to pile back into the SUV. Heading towards the exciting possibilities of the car I found myself walking behind Mom and Karen whose conversation I couldn't help but overhear.

"Karen sweetie would you mind riding up front and navigating for your father so that I can nap for a bit?" Mom asked using her sweetest Mom voice. Doing her best to contain her disappointment at being denied more back seat merriment Karen reluctantly agreed to the seat swap. Fairly disappointed myself I sped up to pass them and climbed in ahead of my cock blocking mother, and slid myself back under Sarah's waiting legs. Mom hopped in after me smiling at how cure she found Sarah sprawled out over my lap. If she only knew that right then her sleeping daughter's exposed belly was full of my cum. Cum delivered by her other daughter's talented mouth. My face split into a huge grin at the filthiness of it all.

Five minutes down the highway my hopes were rekindled when Mom decided she'd sleep better lying down and quickly disappeared into a cocoon of blankets behind the seat. Finding myself in a semi-private situation with my little sister, who seemingly would sleep through anything, I began to form a plan. Eager as I was a few minutes of patience to allow Mom to drift off ensured no intrusions for the foreseeable future. Mom's soft snoring was all the incentive I needed to set my plan in motion. Slowly, I reached over to once again raise Sarah's top over her bare breasts. Her perfect tits begged my touch and teased my imagination. Restraining my urges, for now, I grasped each side of her tight yellow shorts and gently slid them down to her knees. My eyes feasted on a well trimmed tuft of blonde hair and a deliciously tight little snatch. My cock was throbbing and my pants were again being soaked with precum. Wasting no time I slipped out of my pants freeing my cock. Luckily Sarah's pillow against her window blocked any easy view from passing cars. Sliding further over with my cock poking up between her legs I squeezed my aching hard on in between her thighs and right up against her exposed pussy. It was tricky with her shorts around her knees, but finally the base of my cock was slightly parting her pussy lips as the head stood eagerly oozing precum high over her cute blonde pubes. Everything was ready for the next part of my plan. I grabbed my phone held it to the side of my cock angled towards Sarah's face and snapped a pic.

Checking out my own handiwork I had to admit the picture came out perfect since it was taken from near her feet and at just enough of an angle that everything from her tits to her pubes brushing my cock was clearly visible. Smirking at my own deviousness I opened a new text to Karen, wrote 'Miss ya back here', attached the pic, and hit send. It didn't take long for Karen to reply. Her text read 'OMG! That is so fucking Hott! If she wakes up she will freak!'

Knowing that her heavy duty sleeping pill meant she wouldn't be likely to wake I decided to push things further. Reaching back careful not to wake Mom I grabbed another pillow to block the other side window then got to work. First her shorts then her top slipped effortlessly off leaving my little sister, who apparently didn't believe in underwear lying completely naked with my hard cock between her slender toned legs. Lifting her hand from between her side and the seat I positioned her fingers around my cock, and was about to take another picture when a better idea surfaced. Switching my phone to video and hitting record I started to lower and raise my hips. If her sleeping face hadn't been in the frame it would have looked like she was jacking me off with her thighs and hand. After ten seconds I ended the recording, attached it to a text, and wrote 'what's the matter...scared? Didn't seem to worried when spit a load of my cum down her sleeping throat sis ;) '

Waiting for Karen's reply it was obvious that even deep in a pill induced slumber Sarah's body was responding to my attention. The side of my ten inch cock was coated with her warm juices and even with my movements halted her sweet nectar continued to flow against my manhood and down onto my lap and balls. Reveling in Sarah's unwitting arousal I almost jumped when my phone buzzed its announcement of Karen's response.

K 'You are so bad! I am so wet for you...put it between her tits for me : ) '

Having anticipated Karen making a request my response was already ready.

J 'Only after you flash me'

K 'WTF how am I suppose to do that? Dad is right there!"

Again I already knew what to say I wrote 'You'll figure something out :p' , snapped a pic of Sarah after putting her top back on, attached it, and fired off my ultimatum. 'Karen shot back 'No! Don't dress her....ok ok I'll do it. Just give me a minute.'

It took a whole ten minutes but finally a pic arrived and I couldn't help smiling. Karen had fully unfolded a road map and used it to hide her luscious tits fully exposed to the camera as she stuck her tongue out at me. My hard on twitched happily against my younger sister's pussy which responded with a renewed deluge of her already abundant essence. Karen obviously thought I'd been counting on her backing down so I wouldn't have to go further with Sarah. Unlike me she didn't have a clue about the sleeping pills. That knowledge gave me a distinct edge in this game of tit for tat an edge which I would push as far possible. So without any hesitation I stripped Sarah's top back off, slid out from under and between her legs, and straddled her waist. The feeling of lowering my dick between those big perky tits while recording it for Karen was amazing. I couldn't resist squeezing them together and pumping my long hard dick between them. Stopping after a few seconds of titty fucking my sister I zoomed in on the glob of precum my cock had left on her chin, ended the recording, attached it to a text, wrote 'Too bad you won't get to see me explode on her face sis :p' and hit send. Karen replied

K 'Please! Jeremy you have to show me : ( '

J 'IDK...I've already shown you a lot. What can you show me in return?'

K 'Dad is right here and I can't use the map again...'

J 'Oh well, I'll just go ahead and finish without showing you : ('

K 'WAIT! What do you want me to do?'

J 'What are you willing to do?'

K 'Anything but don't get me caught by Dad'

J 'I can't control if you let Dad catch you so no deal.'

K 'Fine just tell me what you want...I'll do anything'

J 'I want a pic of you licking your nipple'

K 'If I do then you will cum on Sarah's face and video it for me right?'

J 'One pic won't earn you that but it will be a start'

K 'No fair! It's way harder for me up here.'

J 'You said you'd do anything...better hurry if Mom or Sarah wake then you'll lose your chance.'

K 'You are making me so horny! Fine I'll do it."

Surprisingly it only took Karen a couple of minutes to pull it off. The pic showed her shirt pulled up over her tits with one lifted up to allow her long tongue access to her hard round nipple. In the background was Dad with his head turned away as he checked the next lane over before switching into it. My balls were throbbing. I couldn't believe how brazen she had been. She was obviously turned on enough to be pushed further.

J 'Ok sis now I want a video of you fingering yourself'

K 'Ok, let me figure out how and I will.'

After several minutes of waiting I could no longer sit there unmoving with my cock between my little sister's tits. Starting my phone's video recorder for when Karen earned it I began to slowly slide my cock between Sarah's tits which immediately began to perk up. Her nipples hardened under my thumbs playful circling as I squeezed her firm mounds around my cock, still slick from her excessive wetness earlier on. The sensations I was feeling titty fucking Sarah were intense and my speed increased rapidly as I felt myself drawing ever closer to inevitable release. Making sure to keep the camera aimed true I began to whisper to Karen "When you watch this Karen I want you to know I am doing this for you". With that I could hold back no longer. My balls tingled and tightened and a deep moan escaped my lips as I blasted the largest load I'd ever shot all over my sleeping sister's face. The first few streams launched so far that massive globs coated her lovely blonde hair leaving long thick trails down across her forehead. The second set covered her from eyes to chin so much so that I wondered if she could breathe, but still more erupted drenching her face even more completely. When my orgasm finally subsided I had no idea how long it had lasted or how loud I'd been and Sarah was sucking in mouthfuls of my cum just to breathe. I watched as huge puddles disappeared into her sleeping mouth. Panic started to set in as I worried that this might be too much and she would wake or that my Mom would wake from her nap to a situation I'd have no way of explaining. Quickly shutting off the recorder I used a pillow case to clean Sarah up as best I could stashing it under the seat after. I knew she'd wake up with sticky hair and a salty taste in her mouth, but she would have no idea why and for some reason that turned me on again. I couldn't help but get hard again as I went about dressing her and myself.

Once everything was back in order I plugged my headphones into the phone and hit play on the video I'd just made. Watching my handiwork was incredibly arousing and just as I feared I'd grunted and groaned loudly when I lost myself in my orgasm. Lucky for me Mom hadn't woken and now that the risk was past I knew my loudness would only serve to turn Karen on even more when she watched an insane amount of cum engulf our little sisters innocent face. Since I still hadn't received a video from Karen I decided to rest my eyes. Almost instantly I was asleep, and the next thing I knew Dad was waking me up with a firm shake of my shoulder saying "Jeremy come on get up we are grabbing a bite to eat so you might want to change out of your sleep pants".

Awareness slowly crept into my mind and I found that everyone else was already gone. Digging into the luggage I slipped out of my pajama pants and into a pair of basketball shorts not bothering with boxers. Sliding out of the car I took a moment to adjust to the brightness then headed into the cheap diner Dad had chosen for lunch. Before I even made it to the table I could see Karen glaring at me over her menu so I promptly took a detour to the men's room to check my phone. Not only had Karen sent me a video she had also followed it with a string of inquisitive and then angry messages about my silence. Opening the video attachment I popped in my headphones and after making sure the door was locked hit play. The video started off with Karen and Dad chatting about when and where to stop for lunch. Pouncing on the opportunity Karen casually mentioned she wanted to change if they would be getting out for lunch and asked if Dad would cover his right side view so she could do so. Reluctantly Dad agreed telling her to hurry so he wouldn't wreck. After fishing out some clothes Karen got a shot of Dad driving with one hand on the side of his face blocking his view. She then used her free hand to slip out of her bottoms and then her top. This left her entirely naked next to Dad who she panned over to show was still covering his peripheral vision. Focusing back on her naked body Karen silently spread her legs and slowly dipped two fingers inside her obviously wet snatch. Her fingers slid in and out reaching deeper with each slow thrust but after only a few seconds the show ended and Karen slid herself into a blue sundress, again with no under garments, then sucked her fingers clean for the camera and ending the recording with a wink.

Now I understood why she looked so mad. She had gone all out for me and assumed that since I'd fallen asleep she wouldn't be getting her promised reward. Once she saw what I'd done for her I knew she would forgive me. All that I had to do was decide when and how to show her.
