Summer 1975. The Vietnam War was finally over, bell-bottoms were everywhere, and my family decided to drive all the way from Chicago to Los Angeles on the old Mother Road — Route 66.
Dad was behind the wheel of our big but overloaded 1969 Buick Electra 225. The trunk and roof rack were packed with suitcases. Mom, Dad, my 19-year-old sister Becky, and me — 18-year-old Tommy.
There was no space left. Becky got the front seat with Dad. That left me and Mom in the back.
Mom was 42 but looked ten years younger. She had that classic 70s beauty — long auburn hair, big natural breasts, wide hips, and thick thighs. She was wearing a light yellow sundress that buttoned down the front, the hem barely reaching mid-thigh. It was hot as hell, and she had already unbuttoned the top three buttons, giving a generous view of her deep cleavage.
“Looks like you’re gonna have to sit on Tommy’s lap, Linda,” Dad said as he loaded the last bag.
Mom blushed slightly but smiled. “It’s only for a few days. We’ll survive.”
The first few hours were innocent. Mom sat across my lap, her soft ass pressing down on my thighs. The Buick had bench seats, so there was some room, but every bump on the old highway made her shift.
By the time we reached Missouri, the real trouble started.
The road got rougher. Mom kept sliding backward until her ass was directly on my crotch. My cock — already half-hard from the heat and the smell of her perfume — started growing fast.
She felt it.
I know she did, because she froze for a second, then slowly relaxed, letting her full weight settle right on my thickening bulge.
“Everything okay back there?” Dad asked, eyes on the road.
“Just fine, honey,” Mom answered sweetly, her voice a little breathy.
The sun was beating down. Mom’s sundress was damp with sweat. I could feel the heat of her pussy through the thin cotton of her panties and my shorts. My cock was now rock-hard, trapped between her ass cheeks.
Mom shifted again… deliberately this time… rubbing her ass slowly along my shaft.
I gripped her hips without thinking.
We drove like that for miles — Mom subtly grinding on my lap while Dad and Becky chatted up front, completely unaware. Every time we hit a pothole, my cock would press harder against her.
Near Springfield, Illinois, Dad pulled over at a gas station.
While Dad and Becky went inside for drinks and snacks, Mom stayed on my lap. She turned her head slightly and whispered:
“Tommy… you’re so hard, baby.”
“I’m sorry, Mom… I can’t help it.”
She bit her lip, then rocked her hips in a slow circle. “It feels… really big.”
When Dad came back, Mom acted completely normal. But as soon as we were back on the road, she reached behind her, pulled her sundress up over her ass, and tugged her white cotton panties to the side.
My bare cock sprang up and nestled right against her wet, naked pussy lips.
“Oh fuck…” I breathed.
“Shhh,” she whispered. “Just stay still.”
She lowered herself slowly. The fat head of my cock pushed inside her tight, married pussy.
Mom let out a soft, shaky moan as she sank down, taking half my length. She was soaking wet.
For the next hour, while Route 66 rolled past the window, my own mother rode my cock in slow, careful movements. Every time Dad hit a bump, she slid down another inch until finally her full weight was in my lap — my entire cock buried deep inside her.
She was breathing through her mouth, trying not to moan. Her juices were running down my balls.
We stayed like that through most of Missouri and into Oklahoma. Mom would clench her pussy around me, then do these tiny little circles with her hips. I had my hands under her dress, squeezing her big soft tits and pinching her hard nipples.
Near Tulsa, she came for the first time — her whole body trembling silently as her pussy spasmed around my cock. I had to bite her shoulder to keep from groaning.
That night we stopped at a cheap motel in Oklahoma. Dad and Becky took one room. Mom and I “had to” share the other because of budget.
As soon as the door closed, Mom pushed me onto the bed, hiked up her sundress, and rode me like a wild woman. No panties this time. She bounced hard, her big tits spilling out of her dress, moaning loudly now that she could.
“Fuck Mommy, baby… fuck Mommy’s pussy on Route 66…”
I flipped her over and pounded her missionary, then doggy style, filling her with cum twice before we finally fell asleep with my cock still inside her.
The next three days became pure heaven and torture.
Every morning we packed the car, and every morning Mom climbed onto my lap with no panties. She’d wear loose sundresses or short skirts and ride my cock for hours while we drove through Kansas, the Texas Panhandle, New Mexico, and Arizona.
She got bolder.
In Amarillo, Texas, while Dad was filling the tank, Mom sucked my cock clean in the backseat.
In Albuquerque, she rode me reverse cowgirl in a deserted stretch of desert highway, her tits bouncing in the open air while the warm wind blew through the windows.
Near Flagstaff, Arizona, on a long winding section of old Route 66, she had a massive orgasm and squirted all over my lap and the seat. We had to stop and clean up with her ruined panties.
By the time we reached California, Mom was completely addicted.
On the final stretch into Los Angeles, she rode me slowly for over two hours, whispering filthy things in my ear:
“You’re so much bigger than your father… Mommy’s pussy belongs to you now… Fill me up again, baby. I want your cum leaking out of me when we meet your aunt.”
When we finally pulled into our relatives’ driveway in LA, Mom stayed on my cock until the very last second. She quickly pulled her dress down, kissed me deeply, and whispered:
“This ride isn’t over, Tommy. Not by a long shot.”
