My girlfriend, "Sha" (sort for Siobhan) and I spent the summer at my parents' house one year. Much sex occurred there, but this is about the drive home.
We got on the road early Monday morning, driving out from Tucson, AZ heading for NY. A little after lunch time, we had made it through Hatch, NM, and we were bored. Yeah, the scenery is spectacular. But you can only take so much of it before you get sensory overload.
So after we gassed up in Hatch, Sha decided to take a nap. So she stretched out as best she could on the front seat of my pickup, on her back with her head in my lap and her legs sort of curled up and leaning against the seat back.
That didn't do much for my boredom, so I sort of "accidentally" let my hand rest on top of one of her boobs and squeezed a little. That got my hand swatted away real quick. So then I turned up the AC and pointed the vents right back at her chest. Having taken off her bra for comfort, that resulted in a very cute pair of chest niblets coming out to play. So I obliged them, pinching and tweaking them a few times before getting swatted away again.
That left just one thing to do: I leaned over and slipped my hand under her shorts, running a finger over her clit through her panties. Awkward phrasing, but I think you get the picture. That got me a moan, so I followed it up by some even more daring under-the-panties clit flicking.
Unfortunately, at that point my attention was more on Sha's nicely shaved pussy than the road, and I had to quickly swerve back into my own lane.
"Oh Fine!" Sha said. "I was going to save this for later on this afternoon, but obviously SOMEONE is in the mood to fool around." So then she flipped over so that she was face down and started pulling down my sweat pants.
If you've never driven between Hatch, NM and Albuquerque, you won't understand just how empty and desolate the Southwest can be. There are towns here and there (Truth or Consequences when you get closer to Albuquerque, for example). But mostly it's just miles and miles and miles of desert. Three hours of glorious NOTHING. Luckily, Sha knew what to do to relieve the boredom.
Sha freed my cock from my boxers and began licking it. I pushed the seat back as far as it would go to give her room to work. "Don't cum right away," she said. "I want to play around for a while." Silly girl- didn't she know that's like telling a guy to shoot jizz RIGHT NOW? I somehow managed to refrain from plastering her face, though. Concentrating on not crashing the truck every time she found some particularly awesome place to lick or suck actually helped me maintain control.
It was by far the longest blowjob I have ever received, and definitely one of the most enjoyable. Sha spent a lot of time just licking the balls and shaft, which I really love. We didn't usually have time for that because it's hard to get private time at school. At the time, she was still learning to deepthroat, so she spent even more time taking just enough of me into her throat to make her gag, and then backing off until the reflex subsided. She'd get herself to the edge, arch her back, and then pull off a tiny bit and stay completely motionless- sometimes as long as five minutes- before trying again. In between deepthroat attempts, she sucked on the head, went back to ball sucking, and licked up and down the shaft.
If I hadn't needed to devote more than half of my attention to the road, I would have blasted my load in fifteen minutes. OK, five minutes. OK, ok. Five seconds. As it was, I found myself amazed and surprised to realize that we were coming up on Socorro, NM (about an hour out of Hatch).
By then, my cock was ready to burst and didn't care about stuff like road safety. Sha could feel it too. I was rock-hard in her mouth, and the head was hugely swollen. She gave up any thought of "just playing" and started a steady, fast, and deep sucking, pausing every so often to try to get the full length of it down her throat.
That was enough for me. I let loose with what felt like a gallon of cum, shooting it straight into her mouth and down her throat. I came for more than a minute- I know because I saw a mile marker flash by when I started splurting and left another well behind us before I finished. We were going roughly 65mph. Do the math.
Sha held me in her mouth for at least another five minutes after I came, something she had never done before. It wasn't planned. As I had been cumming, a family in a minivan had started passing us slowly, and I told Sha about it so that she wouldn't be embarrassed by having them see her raising her head from my lap.
After they finally crept ahead of us, I let her know the coast was clear. Sha gave my softening cock one last deep suck, held it in her throat for an agonizingly wonderful moment, and then sat up to give me the pleasure of seeing her swallow the load of cum she had been sucking on for the last five minutes.
I got road head a total of eight times on that trip, each time as magical as the first. I gave as good as I got, fingering Sha to dangerously intense (from a road safety point of view) orgasms in multiple states and on multiple highways- and yes, they were multiple orgasms.
Since then, Sha has become something of a road-head aficionado/expert. In fact, when we sold the pickup she insisted that we buy another one with bench front seats because she didn't want to try to give head across a couple of bucket seats. We do a lot of long-distance driving because our families are in AZ and NY. Sure, we could fly back and forth for holidays and such, but with Sha in the front seat next to me, why would I want to?
