"Oh, no. That'll make me cum. Your dick's pressing on my prostate. I'm going to cum." Mitch continued to give Randy as good a handjob as he could manage, flexing his hips to meet Randy's riding. "Yes, oh, god, yes." Mitch could feel the ring of Randy's ass clenching around his cock as Randy's cock pulsed with his orgasm. Mitch couldn't hold out any longer, thrust deeply into his brother's ass and released wave after wave of cum into his bowels.
After several moments of heavy breathing, Randy leaned forward to disengage from Mitch. On shaky legs, he pulled his briefs and shorts back on and Mitch pulled his shorts back up. Taking his seat back on Mitch's lap, they rode in silence until, "Hey, you guys ready to stop for a bit? I imagine it's got to be miserable riding like that" Greg called.
"It's not so bad. We figured out a way to make it tolerable." Randy answered.
"Good," Greg said. "Because you're gonna have to do it again when we get back on the road."
"Do it again?" Mitch yelled over the mattress, giving Randy a sly look. "I'm fine with that."
PART II
The van eased off the highway and pulled into the gas station. An almost comically large place with dozens of pumps and a huge convenience store offering everything a traveler might need and an awful lot that they certainly didn't need.
Mitch and Randy rode in silence. Randy leaning comfortably against his older brother, his head resting on the pillow wedged between the car seat and the mattress that separated the van down the middle, completely isolating the passenger side, where the two brothers shared a single passenger seat and their father, driving for hours wholly unaware of what had just happened. Mitch's arm draped lazily over Randy's hip, his hand resting between Randy's thighs. Both were unfazed by the casual but somewhat intimate nature of their seating arrangements.
Once stopped beside one of the many gas pumps, Greg Porter slid from his seat and set about refilling the gas tank while Mitch and Randy unfolded themselves and shuffled into the store, stretching their tired muscles. After a restroom break and the acquisition of an armload of snacks and drinks, the brothers rejoined their father at the van.
"Mitch, finish pumping the gas. Imma head inside for a few minutes." Their father turned and walked away.
"Ok." said Randy. "I'll start. That was really weird."
"I agree." replied Mitch around a mouthful of potato chips. "But, you have to admit, it felt pretty amazing. I'd be lying if it wasn't one of the best fucks I've ever had."
"What the fuck, man?" Randy hissed. "I mean, yes, it felt amazing, but what the fuck? You're only saying that because you were the one fucking, not getting fucked."
"No, really. Ok, I'm sure it was a very different sensation, situation or whatever for you than it was for me but you can't tell me you weren't really in to it." Mitch shut off the gas pump and replaced the nozzle into the holder, retrieved the receipt and began walking back to the passenger side of the van.
"Jesus, yes, I really liked it, but don't you think it's weird or gay or something?" Randy followed his brother.
"Maybe, maybe not. It was the heat of the moment. We were both really horny from the way we had to sit and one thing led to another. I won't lie, I really liked it and you did, too. I'd like to do it again and I think you want to do it again, too." Mitch was adjusting some of the bags and boxes in an attempt to make a little more room in their seating area. He also grabbed another pillow from his basket of bedding and set it on the seat.
"Shit. Yes, I do." Randy muttered mostly to himself.
"What was that?" Mitch teased. "Do what?"
"I want you to fuck my ass again." Randy looked Mitch in the eyes. "I haven't been able to think of anything else since we finished, only when can we do it again." He trailed off for a moment, then said, "Shit, hang on." Randy turned and headed back into the convenience store.
Randy's dad was heading back to the van when Randy quickly walked by.
"Where's he going?" Greg asked. "I thought we got everything we needed. Didn't you guys use the restroom?"
"I don't know. Maybe he forgot his favorite candy bar or something. I honestly don't know." Mitch replied.
Greg looked into the open sliding-door of the van at the space Randy and Mitch had carved out for themselves. "Not so bad, I guess. You going to switch it up and sit on your kid brother's lap this time?" he joked.
