Leaning against the window, as I was, I could see the long straight strip of concrete that was the road ahead disappearing into the distance. The occasional semi that we overtook was a relief from the otherwise utterly boring and flat landscape of west Texas. Or was it now Oklahoma? I didn't know, it all looked the same. Even the semis were few and far between as most now stayed on the interstates whenever possible. Wichita Falls was just ahead, or had we already gone through there and it was just behind? I couldn't remember, everything out here in the "Great American Desert" blended into everything else.
Yesterday we'd been to Carlsbad Caverns, our one planned respite from the devastatingly long trip back to the family farm where Mom had grown up. We hadn't seen that part of the family in perhaps 10 years and, except that I'd agreed to this trip many months ago before I'd started at the University, I really didn't want to be here.
Planned as the "last" family vacation, and a "You Graduated!" trip to celebrate my sister Andrea's graduation from High School this year, as well as a belated celebration for my graduation last year, it would have been familial suicide to try and back out. But I had kept a smile and tried not to show my disapproval. I don't know exactly how successful I was.
Although my eyes were on the road, my mind was thinking back to my last day at school, the last day of seeing my girlfriend, Stephanie. At least, she had been my girlfriend to start that day. I had gone to her room early, after I'd finished packing my stuff. I'd helped her pack her last things, and then we'd showered together and fucked each other silly while doing it -- and then she broke up with me. Or, at least she said she didn't want to be tied down to someone who was in another city or vacationing with his family while she had to stay home and have a summer job and no relationship nor dating. She wanted to be able to "date", which I knew from our relationship meant that she wanted to get fucked -- and regularly. I was upset to begin with but had to admit she was right. Before the weekend was out, I had already admitted to myself that having a handy lover was nice, but we weren't soul mates or anything like that.
But now, in the car watching a boring Texas roadway or trying to count the cars on the occasional miles long train, I felt my cock getting hard as I thought about the last few months Stephanie and I had spent together. She loved to suck cock, she loved to fuck, she loved to have her pussy eaten - and in that respect, we were very compatible. Absently I reached down and repositioned my cock, without even thinking that I might be visible to anyone else. That I was under observation became obvious a minute or so later when my phone buzzed in my hand. A week before I would have expected the text was from Stephanie, but she hadn't even said hello since I kissed her goodbye last week. Instead I saw my sister Andrea's name, and a one-word message.
"Horny?"
Even as I turned to look at her across the bench seat of the back of our Toyota SUV, I saw her push the send button again, and her eyes came up to meet mine.
"M2" was the second message.
There was no doubt that I was horny. My cock was hard, I was thinking of sex, and if I wasn't in the back of this damn car in the middle of nowhere, seemingly going to the middle of nowhere as the view hadn't changed for about 4 hours, I would have been grabbing a magazine or flipping through some on-line porn and wanking my noodle.
Even as my eyes were evaluating my sister, the events of the previous Christmas poured through my mind. My yearly ritual, of watching mom and dad fuck under the tree while I whacked off, had been discovered by Andrea. She'd masturbated herself watching me, and then when I'd discovered her, she'd joined me and for the first time ever I'd touched my sister. She'd touched me, too, as we mutually masturbated each other. We'd talked briefly about it during the next couple of weeks, and she'd indicated it was fun, but she really didn't want to do it again -- at least not with her brother. She'd had her boyfriend "handy," I'd had nothing but my hand until I'd gone back to school a few weeks later at the end of Winter Break -- and had met Stephanie. I met her at a frat party, the sparks had been obvious the first time we met and talked, and we'd been inseparable ever since -- at least until last week. Something about the way it happened I knew it was over forever, even though she had said it was only for the summer.
For some reason, my attention was drawn to Andrea's face, especially her lips. She normally had warm, full lips, but now they seemed a bit plumper, a bit redder than normal, and somehow, I knew it was from arousal. My friend Jerry, who had been panting around Andrea and getting nowhere for years, always said she had cocksucker lips. The first time he had ever said that I'd bruised his arm with my fist, now he said it just to spite me. Right now, for some reason (perhaps that I had been imagining my cock being sucked, although not by my sister) I had to agree. As I watched she pulled her lower lip between her teeth, looked down at her phone and typed something.
"Remember Christmas?"
"Yeah."
"I wish we could do that right now."
"Yeah. M2." Her tongue slipped between her lips momentarily as she licked them. I had no doubt she was thinking of sucking cock and momentarily I imagined her lips in my crotch. My cock lurched in my pants, binding on my underwear. I straightened my cock again, leaving it upright behind my zipper, this time knowing she was watching as I did. She looked back at her phone and moments later mine buzzed again.
"It's almost out of your pants?"
"Yes"
"Show me. I want to see it."
I'm sure my eyes bugged out when I read this, but not as much as seconds later when I looked back over to Andrea. With her eyes locked on mine, she raised her left hand to the waist of her shorts and slipped it inside.
I couldn't see but I was sure she'd slipped her fingers inside her panties too, and from the movement visible through her shorts I knew she was touching her clit. "Show me," she mouthed wordlessly, her eyes dropping to my shorts.
Any thoughts of "we shouldn't be doing this" or "she's my sister" were gone, we were just down to a horny guy and horny girl and she was asking to see my cock while she got herself off. I slipped my hands down to the waist of my shorts, sucked in my gut just a bit and pushed down. My cock, which had been resting just behind my belt barely out of sight, now slipped into the open as I lifted my hips and pushed down with my thumbs.
I only had the head and perhaps an inch or so exposed, not enough to wank - not that I'd really want to in that situation with Mom and Dad just ahead of us in the front seat. I knew Dad would never look back unless there was some loud noise, or something to draw his attention, but Mom was a different matter. She would occasionally, right out of the blue, turn and look back over the seat and say something like "How are you kids doing?" If she did that, she would be looking at Andrea and, if it was obvious to me that Andrea was masturbating, I'm sure it would be to Mom, too. But it didn't happen.
Andrea was quivering to her own touch, her right hand rose to her breasts, brushing back and forth caressing them before her fingers found and pinched her nipples through the cloth of her shirt and bra, her eyes never leaving mine. It was just moments before her hand lowered to the bottom of her shirt, slipping back up under the shirt where I could see her push her bra away to touch her nipples directly.
I had my right hand playing with myself now, keeping it beyond my belt so that she could see me. I reached up and spit into my fingers to provide some lubricant and caressed my cock head, virtually all that I could do for myself in the car like this. Andrea's tongue slithered between her lips again, and I wondered if she was imagining a cock between them -- my cock, or Donny's? It didn't take long, and a harder convulsion racked her body, her stomach clinching, her fingers in her pants stilling, and I knew she'd orgasmed. Her hand in her shirt also stilled, and then slowly withdrew. "Thank you," she mouthed.
My pants easily slid back up when I pulled them, my cock slipping out of sight, and thumbing my cell I texted her "Tits?"
She glanced at her phone, and seeing what I'd written, reached in with a finger and opened her shirt, her finger lifting her bra underneath. I could see down to her nipple, of that I was sure, but it wasn't quite the same as me getting my cock out. I rolled my eyes at her and mouthed "more". Her hand went back to her phone.
"You want to see my tits?"
"Yes."
She got a smirk on her face, glanced forward once at Mom in the front seat, and quickly pulled her shirt open giving me a quick peek at her bra enclosed breast. I rolled my eyes at her, getting a grin in response and I texted, "No fair. Nipple."
She pulled her lower lip between her teeth momentarily, and then unexpectedly unbuckled her seatbelt and slid to the center of the back seat, leaning forward between mom and dad and said "I'm kinda getting hungry, are we going to stop pretty soon?" We all discussed it, deciding that in about an hour we would stop, when Andrea suddenly twisted her arm behind her back and began trying to scratch her back, right in the middle. "Oh! Oh!" she said, and then "Rick! Can you scratch my back?" and pulling her shirt up almost to her shoulders exposed her back and her bra strap, her thumb indicating right at her bra strap was where it itched. I didn't hesitate, reaching over two handed I began to gently scratch her back all over. "No! Right There!" she said, her thumb once again pointing right at the clasp of her bra. I hesitated just slightly but moved my fingers to her bra strap, thinking she wanted me to actually scratch around and maybe under it -- when it dawned on me what she might be saying. When I reached with both hands, gripping the two halves, her "Yes! Just like that!" told me how she'd decided to have me unhook her bra. As soon as I released it, she said "Oh Thanks! That's perfect!" and pulled her shirt back down. Sliding back into her seat she re-buckled her seat belt and looked over at me once again with a smirk.
As I watched she first slipped her left arm inside her shirt, and then I could tell she was slipping her bra over her arm. She got her arm back outside her shirt, and then moments later she repeated with the other arm. Reaching up from underneath the edge I saw her pull her bra out, fold it and, reaching down, slipped it into her bag and out of sight.
Although the shirt my sister was wearing wasn't sheer, it did have a v-cut front that I knew, now that she was braless, all she had to do was lean forward and I'd be able to see her breasts. That's what I expected.
What I didn't expect was that she would pull the shirt down and totally expose her tits to me. With just a little spreading of the v-cut, she slid it slightly left and then slightly right, both of her breasts popping out of her top, the whole time looking at mom in the front seat to make sure she wasn't going to turn around.
I was mesmerized. Although we had played together in the dark at Christmas, I hadn't really gotten to see my sisters' gorgeous tits except through the dim reflected light from the Christmas Tree. Now, in the light of day, I could see how nearly perfect they were. They seemed to be supported by her top, but having already played with them at Christmas time, I knew they would be upright even without that support. Two perfect ripe peaches, slightly puffy around her nipples, of which both nipples were currently erect. She glanced for a moment at me and smiled, looked back at Mom in the front seat and deftly moved her top, her tits instantly falling back into place. I don't know whether Andrea saw Mom turning or just sensed it, but a second later Mom had turned to look at, and say something to, Dad.
"OMG sis, gorgeous tits. Suckable."
