Based off a true story.
-----
It was three weeks on the road, we were cruising highway speeds down Interstate-90 coming from Billings through to Chicago in our RV, it was the early afternoon.
My husband Simon, age fifty-four, was driving, with my twenty-one-year-old son Tony, in the passenger seat, navigating. I'm forty-four, work out every day, eat well, and I'm proud of my body. I lay out in the back, on the queen-size bed, reading a book, separated from the rest of the cabin by a thin curtain. I'm wearing a thin tank tap, no bra, and little red sweatshorts.
The mid-States' heat was humid and muggy, an overall-hot day. We had the AC running, which made things comfortable, but it also made the cabin pretty loud.
"I'm going to take a nap!" I shouted over the roar of the engine, wheels, and the generator running which was powering the AC.
"Do you boys want a snack before I do?"
"What?!" my son and husband shouted.
They couldn't hear a thing I said. I got up, poked through the curtains and made myself to the front, swaying side to side with each step from the movement of the RV. My tits and ass jiggled from the vibration. I saw Simon look up into the rearview mirror and smile. I knew he was glancing at my body, which he'd say was sexy, at least five times a day.
I pressed against the back of the passenger seat, and ran my fingers through Tony's hair.
"I'm about to take a nap. Do you boys want a snack before I do?"
"I'm okay," my Simon replied.
"I'm okay, mom, but I'm beat too. I'll join you for that nap." My son looked back at me to make sure that it was okay.
"Yes, come." I waved to him to welcome him back.
I headed back and my son followed. I opened the curtain, bent over on all fours, and crawled in on the bed; he climbed in the bed behind me. For sure, he had a good view of my tight ass, as we settled into the bed. He shut the curtains behind him, then lay beside me.
I closed my eyes, the vibration of the road was making me sleepy. Tony reached over and held my hand, which I thought was sweet. I interlocked fingers with him, and lay there. About ten minutes later, I felt his hand slide under my shirt and caress my stomach and move closer up to my breasts.
My son's movements were sly, smooth, and very slow to not wake me.
I pretended to sleep, my breathing got heavier and slower, as I took in the feeling of his touches. It was kinda hot-- my twenty-one-year-old son exploring his mom.
I lay there still. I was curious to see if he had the courage to take it further. He inched his way up, and stopped below my right breast. I kept thinking, that little perv, but I was too into it stop him.
I opened my eyes and looked directly at him.
Our eyes locked onto each other. I felt butterflies in my stomach which floated to where he was touching me. Tony moved his hand up and cupped the bottom of my right breast.
"Does this feel okay, mom?" Tony asked.
I nodded, biting my bottom lip. "Yes honey, this feels good."
I looked down at where my son's hand was touching. Tony's eyes followed down to where my gaze went; he moved his hand higher, sliding above my nipple, and pinching it gently.
"You have the most beautiful breasts I've ever seen, mom." My body vibrated, taking a deep breath, as he was fondling his mom's breasts and pinching his mom's nipples.
I quickly looked at the curtains; they were closed, flapping, my husband was on the other side driving, completely oblivious that our son was grabbing a feel of his mother's breasts.
I lifted up my white tank-top shirt, releasing my 36DD breasts, exposing both of them to my son. I reached around the back of Tony's neck and ran my hand through my son's hair.
"Come, suck on mommy's breasts." I pulled my son's face in, as he opened his mouth and sucked my nipple, taking as much of my breast into his mouth as he could.
Tony's eyes met my breasts, then looked up at me as they made eye contact.
"I've wanted to suck your tits for as long as I can remember, mom." His saliva coated me, as he sucked and slobbered all over my nipples and breasts.
"You're a good little boy for mommy, aren't you."
"We've been on the road for so long, I haven't been around my girlfriend. I'm so horny."
"Yes, I understand, sweetie." I reached down and placed my hand on my son's bulge.
The soft grey jogging shorts he was wearing were loose fitting, but a huge tent appeared in the front from his rock-hard cock.
"Wow, you're so big." I looked into Tony's eyes, as I stroked him up and down, admiring his thickness, length, and girth with both hands through the fabric.
"Just a second, sweetie. Let's make sure the coast is clear." I peeked my head through the curtains. "You doing okay up there, love!?"
"Yeah, I'm good. I may switch out with Tony at the next stop, we'll be there in about twenty minutes."
"Okay, sounds good, I'll let him know!"
I pulled my head back and closed the curtain, then slid my face down to my son's crotch, and with both hands pulled down his shorts.
Tony's cock sprang out, poking straight in my face.
I looked up at him. "My poor boy, you must have so much cum built up from being on the road with us for so long and we don't have your girlfriend here to drain you."
Tony nodded.
"Don't worry, mommy will help drain your balls."
I parted my lips open and took my son's cock in my mouth. He grew to be nice and large, about the same size as his father's cock. At first, I sucked on his sweet mushroom head, then took more and more of him in, until he hit the back of my throat.
He tasted salty and sweaty from the heat, which excited me even more.
I have no gag reflex from sucking his dad's cock all the time.
I bobbed my head back and forth, sucking, slobbering, and stroking the shaft of his cock with my saliva as lubrication. When I pulled back, I sucked harder on the tip of his cock, rolled the tip of my tongue in the slit of his penis, which made him thrust his hips forward, ramming the back of my throat.
This went on for a while, on repeat.
