Thanksgiving vacation

It was a wednesday, loading the van, dressing warm, packing warm clothes, and I knew my nieces and nephews would want to play outside but the only thing I had on my mind was playing football in the snow. Its kind of a get together tradition, rain, snow, didn't matter, it was a friendly game while dinner was cooking, tackle, no pads, guys from 10-50, usually a great time. "If this takes any longer we'll be getting there in time for bed!" said my dad. "She's on her phone in her room" I told my dad, referring to my s****r. "Lets GO!" he yelled as he went in the house, my mom was already in the van, rolling her eyes, probably thinking about what are the neighbors thinking. Sara came down the stairs, threw her bag in the back of the van & jumped in, my dad locked the door as I jumped in the back doors of the van, he got behind the wheel "Now, do we have everything??" he asked to everyone,, "yes" we replied in perfect unison & we were off on a 3 hour drive. Pretty tedious my most standards, ocassional bathroom break, snacks in case we needed, a cooler with beer for my dad & my moms nose in her book for about the 1st hour, then sl**ping. My dad liked driving with the window open, so there was always a cold breeze blowing through, and plenty of blankets if you got cold and a pillow or 2 if you got tired. I should have brought homework along, but forgot, so I jumped in the back by tyhe bench seat, so I could stretch out if I got sl**py. I must have dozed off because I was woke by Sara when we stopped for gas, she was carrying a blanket and pillow & looked like she was gonna nap, "how much longer?" I asked her, "Little over an hour" she replied as my parents got in, started the van & continued our trip. "Can I curl up here" Sara asked as she sat next to me, putting her head against my shoulder, "I guess" I replied. And with that she dropped her pillow, threw the blanket on top of us & curled up. I looked at my mom, she was looking at us, smiling & looked back to the road. Sara got comfortable, putting her right hand on my stomach as she leaned on my shoulder, feigning sl**p. As we bounced on down the road, I started thinking about football, relaxing & watching TV, (no video games yet,,) and yes, eating a big turkey dinner. I must have been in my own little world, Sara's hand had slipped off my stomach and was now resting on my crotch, I thought nothing of it since only a few weeks earlier I had fucked her & her friends at the sl**p over and taught her how I liked a blow job days later. Well my subconscious must have thought of other things because the ever so slight pressure of her hand on my dick was causing it to get hard & in a uncomfortable position! It was starting to hurt & I was unable to straighten it out to make it stop hurting,, I tried shifting my weight, wiggling my ass with the bumps in the road, nothing. So I reached for the top of my jeans to get under the waist band & straighten it, when I heard Sara whisper "I'll get it" and with that, from the outside of my jeans, she grabbed my dick, in the middle of the shaft & pulled towards the zipper, "Damn it" I growled at her, it hurt. "Sorry," she whispered as she unzipped my jeans, wrapped her hand around my dick, still in the boxers. "What are you doing??!!" I asked her in a low tone so my parents would not hear. "Making sure you are not hurt or bleeding,," she said. "Fuck, you don't grab my dick & yank on it like that" I whispered, "Soooorrry!" she said, slowly stroking my dick as I was forgetting the pain I was in just seconds ago. As I looked up at my parents in the front, to see if they could see anything, Sara pushed my boxers down into my pants, below my balls, and when she thought they would stay that way, went back to stroking my dick to full length. I gotta admit, it felt better, getting it out like that, and getting a hand job with my parents less that 5 feet away. Without trying to make it obvious to anyone in the van, I tried sliding down the seat, until I was just at the edge & then slide back up, using the seat to pull my pants down, so I could get the full feel of this. Sara did nothing the 1st time, and they came down a little, so I tried again, as I did it this time, Sara slid her hand between my legs, back to my ass & pulled them down just far enough to really stroke my dick, move it around & play with my balls. She really knew what she was doing, because she has never done this before to me. She looked me in the eyes, smiled as her eyes shifted to our parents & back to me. As I turned my head to look up front, she let go of my dick, now just bobbing freely under the blanket, looking like a tent pole when I turned back, looked at Sara as she was fidgeting under the blanket, thinking to myself, "uh hey, finish what you started!", when she looked back into my eyes with that mischivious smile I've seen before, and grabbed my dick again, only this time her hand was soaked! "What did you do?!!" I whispered, "I'm so fucking horny, I needed something in me, so I put 4 fingers in,," she whispered with a sly smile. "Uhhhh, feels great!" I told her as she continued stroking my dick with her pussy juice soaked hand. "I know,,, finger me,,, now" she said, thinking she was in control, "NOT NOW!" I told her, after all, yea my mom was asl**p again, but I did not want to get caught having sex with my s****r, IN THE VAN, WHILE my dad was driving! As she kept stroking, I knew I was not going to last much longer. Looking in my eyes, she knew I was close, "ooow, getting harder, must be close to cumming,," she said with one of those, fuck me now looks. "Uhhh,,yea,,," was all I could say as I tensed up a little, tried to hold out as long as possible, trying to think of how I would clean this up & not get noticed or caught. But she just kept stroking, picking up speed, gripping a little harder, gently squeezing the head, sending sensations up my back, as I tensed a little more, trying my best to hold back. "Uhhh,,, damn it,, uhhh" I muttered as she dove below the blanket, putting my dick in her mouth as my head spun towards to front, watching my parents with that pained "fuck face" us guys will get just before cumming, as she dove down on my dick, pushing her nose into my stomach, swallowing my dick in her throat, with no gag reflex, she grabbed my ass as I blew a load down her throat, all the time watching to see if there was any reaction from my parents. As the spasms subsided, she stuck out her tongue & licked gently accross my balls, with a sweet suction, sucking every last drop out of my dick. And just as fast as she went under that blanket, she was up, like nothing even happened. I was still watching the front seats as I quickly grabbed my pants & pulled them up, not even caring about my boxers, Still covered with the blanket, Sara pulled up her underwear & pants, "Wha" was all I could get out as she put her right hand over my mouth. Her fingers smelled of that sweet musky smell of pussy, and the finger that brushed my nose was still sticky wet, and without even thinking, I grabbed her wrist and put her fingers in my mouth, smelling the essence and tasting her sweetness. As I closed my eyes and she slowly pulled them out of my mouth, my dad yelled "We're here!" and with that my mom sat up, Sara jumped towards the front seats to look out the windows, turning back at me with a smile, "Its snowing!" she said as my dad put it in park, I tried fixing my boxers as Sara pushed me into the seat as she moved past me, "Let me out,, Dork!" she said, making her way to the back door, she turned back to me, smiled & thats when I saw a drop of my sperm on her sweater, near her shoulder. "Bitch" I said, pointing at her shoulder. She looked down at it, wiped it off with 1 finger & put it in her mouth, "Mmmmmmmm" she said with a smile & ran into the house. This was the best start of a short vacation, that I will never forget,,
