Backseat Mommy: A Long Hard Ride

You don't really know how much stuff you have collected in your life until you move.

With our last son going to college, we did two moves in one. We were moving to a condo only a few miles away, while we were driving Cory sixteen hours to college. Because we had to put all our items in storage, we didn't get title for three more weeks, we were going to do a two week road trip after we dropped Cory off.

As we packed the car with both Cory's stuff and our suitcases for the almost three week round trip, we realized we had a major predicament. By the time the car was loaded, there was only room for two people. A driver and someone sitting in the back seat behind the driver.

My husband tried to reshuffle the luggage, but there was simply too much stuff.

I finally suggested, "Cory and I could squeeze back there together."

"For sixteen hours?" My husband, Alex, asked.

"Well, we will likely have to take more rest stops," I shrugged.

"Based on your small bladder, that will be the situation regardless," Alex quipped, always annoyed by how often I made him stop. He was a put the pedal to the metal kind of guy, while my bladder was a stop and smell the roses type of bladder.

I turned to Cory, who was slim like me, "Can you handle sixteen hours cramped beside your old mother?"

"Oh, if I have to," my son, always sarcastic, responded.

"Be careful with that attitude," I shot back playfully. "You're stuck with me for sixteen hours."

I should note it was a very hot August day and I was wearing a sundress for the drive to stay as comfortable as possible.

We all did one more pee check, which I, of course, did, and Cory and I squeezed into the spot made for one.

Alex asked, using sarcasm too, "Comfy?"

Cory's elbow poking my breast, I quipped, "Like a cow on a train."

"Moo," Cory added, shifting more which led to even more pressure on my left breast.

We were just out of the city, half an hour later, when I said, "This isn't working."

"You don't like being a sardine?" Cory asked, as he stopped reading on his IPad, like I too was trying to do, the kindle app the only app really worth owning.

"Not particularly," I nodded, as I moved and suggested, "Maybe I can just sit on your lap for a while."

"Okay," my son nodded.

I moved onto his lap and sighed, "Now that is much better."

"Agreed," Cory said.

"I'm not too heavy on you, am I?" I asked. At forty-six I was still in great shape. I was slim with big breasts, a firm ass and legs. Selling real estate I knew that my looks played a key role in my sales. Sex sells, always has, always will. So I dressed in professional, but sexy business suits or dresses with nylons and four inch heels. My 38d natural breasts always were showcased as I'm pretty sure they helped me close more deals then the actual real estate I was selling.

"No," he answered, shifting slightly.

As we drove, after a few minutes I noticed two things:

1. Wearing a dress was a bad idea as I was now sitting on my son's lap, my thin thong the only thing stopping my vagina from being directly on my son.

2. My son's cock was hard and placed directly under my vagina.

My son, who was rather nerdy in high school, like his father, winning a full ride scholarship to over a dozen colleges, had really blossomed physically by working construction all summer. Gone were his scrawny arms, replaced with impressive muscles. I had complimented him frequently on his summer reformation. My boy had become a man.

Yet now, as we drove on a bumpy section of road that was under construction, I realized my boy had indeed turned into a man as I could feel his definitely erect cock directly under me.

With each bump his hardness rubbed my pussy which, even though I tried to control myself, got me wet. I considered moving, but was worried I would embarrass him if I acted like I could feel his erection. So, instead I tried to control the bouncing by putting my hands on the top of the seat in front of me.

Yet for about ten minutes, which felt like an eternity, my son's hard-on, thankfully trapped in his shorts, rubbed against my very wet pussy.

Finally, the road smoothed and now his hard cock just rested directly underneath my pussy. I knew I should move, yet I still seemed frozen in place. Partly, because I was worried I would embarrass him if I moved and partly, undeniably, it felt good in the position I was in.

For twenty minutes my pussy rested on his cock, which never shrunk, while talking to my husband as much as I could to distract me from the awkward situation I was in.

Finally, I saw an upcoming rest stop and suggested we stop.

Just as Alex slowed down, I felt the firm flinching of his penis. It flinched three times, each time lifting up ever so slightly into my pussy lips.

I accidentally moaned.

Alex asked, "You okay?"

"I just need to stretch," I answered, my face burning red at the reality that I was getting horny from sitting on my son.

"I could grab a drink," my husband nodded, as he pulled into the car stop.

"Me too," I agreed, suddenly feeling a bit dehydrated.

Once he rolled to a stop, I joked to Cory, "I imagine you are dying for a break, too."

"No, I was enjoying the ride," my son answered, yet his tone didn't imply any sort of sexual innuendo that could have accompanied those words.

My already flushed face went a shade redder as I opened the door and got out. I'm not sure if my face could go redder, but as my son got out and stood up two things were apparent:

1. His erection poking out if his Adidas shorts.

2. A wet spot that was undoubtedly from me.

I turned away and headed to the washroom mortified that my pussy juice was on my son's shorts. Once inside, I pulled my panties down and couldn't believe how wet they actually were.

Now I should note I got wet easily and was quite a flooder when I got off. I also had a ferocious sexual appetite that my husband could seldom feed completely... thus I had a variety of sex toys to finish the job he often couldn't complete. I had a we-vibe, a couple vibrators, anal beads, a butterfly toy that I could wear while out, which was in my purse, and my newest purchase acquisition, a massage vibe... which was literally orgasmic.

Deciding I needed to quell my burning cunt, I leaned against the wall in a stall and began pleasuring myself. Not surprisingly, the half hour plus of accidental teasing had me already revved up and I came in no time at all. My pussy juice leaked down my leg and I awkwardly cleaned myself up with toilet paper.

Once recovered, I also wiped my panties as I tried to make them less damp but after putting them on all I could still feel was my humiliating wetness. Usually, I loved sex. I loved coming, but the constant reminder by my wet panties that my son's cock had got me horny was too much and I took them back off.

Instead, I put the sexy wet thong in my purse, and went to the sink to wash my hands and legs. Unfortunately, a mother with her child were there and all I could do was wash my hands thoroughly to hide the scent of my own cum.

Leaving the washroom, I decided there was no way I would sit back on my son's lap, instead, deciding we would have to persevere squished side by side. I purchased a coke and a bag of chips and headed back outside.

'Fuck', I sighed as the summer heat pounded on us. It was a fucking sauna out there. I planned to try and get more panties from the suitcase, but decided not to, how was I going to explain that?

My husband and son were leaning on the car chatting when I walked over.

"So, under fourteen hours left," Alex quipped, with a playful smile.

Cory added, "I think it's going to be a tight ride."

I couldn't tell for sure, maybe it was just the self-conscious part of me, but he seemed to stress the word 'tight'.

I joked, realizing only after I said it that it only added to the innuendo if he was implying any, "Yes, it is some quality mom and son bonding."

"Well, it's you two back there the whole drive," my husband added. "No way can I fit back there with anybody."

That was true. My husband was a bigger man and there was no way my son or I would fit side by side or on his lap.

Nope, I still had just under fourteen hours with my son in the backseat. The next few without any underwear.

Fuck.

My son got back in the car first and patted his lap.

I was supposed to go in first and suggested, "Shouldn't we try to be side by side?"

"It's okay, Mom," he said, patting his lap again.

"You sure?" I asked, knowing I wasn't wearing any panties and my pussy was still slightly damp... the aftermath dribble of a good orgasm.

"Side by side is too tight," he replied.

"But I'll crush your legs," I pointed out, desperate to avoid sitting on his cock again... having apparently enjoyed it too much the first time.

He shrugged, "Oh Mom, you're light."

"You sure?" I asked again, still tentative, as I looked down and could still see the remnants of a stain on his shorts as well as the clear outline of his cock... which, at least, no longer looked to be completely erect.

"Mom, it's not hard at all," he answered, his word choice odd.

Naughty me also wanted to respond, 'but it likely will be', but the good mom in me responded, "If you're sure I won't smother you."

He shrugged, "I can handle whatever you give me."

So I sat back on his lap, his words again dripping with possible innuendo, this time moving more onto his leg and avoiding his crotch.

For half an hour, I sat in that spot as we continued driving. Then suddenly I felt his hands on my hips as he stated, while lifting me up slightly, "We need to change positions."

When he lowered me back down, my pussy was again directly on his indeed again stiff cock. I couldn't help but let out a slight moan as my naked pussy felt the pressure against it.

For the next half hour, even though the road was smooth, I kept feeling his cock seem to flinch, which made my pussy tremble and get excessively wet.

Alex asked, "Comfortable back there?"

My son said, "It's tight, but good."

I gasped as, while he said this, I felt three clear movements of his cock.

"You okay, Sarah?" Alex asked, as I felt my wetness leak out of me slightly.

"I'm good," I responded. I wanted to move, but knew without that a doubt I had created more wetness on my son's crotch and if I moved it would be clearly noticeable... being able to have multiple orgasms had always been a great benefit to me, but at the moment it was my kryptonite.

"Next stop is almost an hour away," Alex said.

"No worries," I said, trying to be causal.

Cory added, "Yeah, although it's getting hot back here."

"The air is on full," Alex said, and I indeed wasn't overly hot, except down below. This time his words were definitely implied innuendo. My son was flirting with me.

"I think it's Mom's body on mine," Cory said, as he again flicked his cock directly against my pussy... the intent now definitely clear. His words also had two very different meanings.

After another minute, Cory asked, "Can you turn the radio up?"

"If I do, I won't be able to talk with you, I barely can hear you now," Alex responded.

"That's okay," Cory said, "we'll let you drive and rock out to your eighties tunes."

"It's the eye of the tiger," my husband sang, as he turned up the radio to the Survivor tune.

Cory was on his phone. Suddenly my phone vibrated.

It was in my purse, so I reached down and in doing so I ground my pussy on my son's very hard cock. I couldn't deny it... I was incredibly aroused.

I grabbed my phone and moved back again, unable to not grind my very wet pussy on him again and saw the text was my son.

Perplexed, I clicked on it.

Why are you not wearing panties?

I gasped again. Although this time the music was too loud for my husband to hear it.

I didn't know what to say.

A second message followed.

Why are you so wet?

I still didn't know what to say.

I was paralyzed with indecision. Obviously, I should stop this inappropriate talk in its tracks. Yet, I was incredibly horny and was not thinking like a mother or a wife but as a wanton woman.

As I stared at my phone, shocked by my son's brazen words, and yet equally turned on, I was startled as I felt Cory's hands on my hips as he lifted me up.

I leaned up slightly on the driver's seat, bumping my husband's chair.

Alex looked back and I said, trying to act casual even as my mind was mush, "Sorry, just changing positions."

"Sorry about this," he apologized.

"It is what it is," I replied, as I felt my son's hands on my hips as he lowered me back down on his lap and...onto his cock!

I yelped in surprise and Alex asked, as he turned down the radio, "You okay?"

"Yes, I just got poked," I weakly responded, unable to not say something naughty, an amazing pleasure coursing through me as my son's, cock, which felt bigger than my husband's, was buried in me, his hands firmly on my hips holding me in place.

"Okay," he nodded, as he turned the radio back up as another eighties tune, Bryan Adam's 'Summer of 69', began.

I just sat there; still in complete shock that my son's cock was buried deep in me.

I just sat there; the urge to ride my son's cock growing with every second it was inside me.

I just sat there; wondering what my son was going to do next.

I just sat there; secretly wishing my son would take more control.

I just sat there; worried that if my son did take control I would be unable to hide the obvious reality that we were committing incest just inches away from my husband.

I just sat there and enjoyed the ride, every bump in the road creating a new pleasure as Cory's cock would rise up inside me. I had to use all my will power to not moan, to not alert my husband to the incestuous adultery I was willingly committing.

Yet, I was frustrated that my son who had been so brazen to slide his cock in me, was now just sitting there reading his kindle as if his cock wasn't buried deep in his mother's box.

I just sat there for over half an hour doing nothing but allowing myself to be teased like crazy.

I had to use all my willpower to not just give in the insatiable hunger to ride my son's cock.

I had to use all my willpower to not moan on every bump on the highway, especially when Alex occasionally hit the warning bumps making my body tremble and my pussy quake.

I had to use all my willpower to not grind on his cock to get myself off, the teasing of a cock in me and not doing anything driving me nuts.

Alex startled me, my head clouded, when he announced, "Twelve miles to the next stop."

This seemed to make my son finally take control. He began to slowly lift me up and down on his cock.

I clenched my teeth to make sure I didn't moan as a mixture of emotions went through me.

Excitement at my son finally taking control.

Humiliation at the fact I was excited he was taking control.

Pleasure as the slow fucking coursed through every pore of my being.

Frustration that he wasn't fucking me hard like I liked it, yet knowing there was no way that was a good idea.

Guilt as I was allowing my son to fuck me. Theoretically, when his cock was lodged in me I hadn't let him fuck me. I had only allowed him to penetrate me. I know it was a technicality, but it was all I had left to grasp to... And now that was gone.

My son let go of my hips, giving the decision to me.

This was my chance to stop this. To lift my body up and allow his cock to slip out of my very wet pussy. To take control of this bizarre situation.

And I did take control. Although not as a mother, but as a horny slut.

I continued the slow motion riding that my son had been controlling.

Suddenly, it wasn't my son forcing me to ride him, it was me willingly riding him... although slowly, which only compounded my frustration as I knew I would never get off like this.

I needed to bounce on his cock hard.

I needed to ride it fast.

I needed it slamming into me. I didn't make love, I fucked.

Yet, I couldn't do any of those without giving away completely the shocking truth of what we were doing.

Suddenly my phone, which I had put on vibrate, buzzed in my hand.

I looked at it.

Fuck, I love you, Mommy.

Reading those five words... reading the most sweet, endearing term for being a mother... and I was a mess.

I couldn't deny that I felt something so powerful as his cock slowly filled me, as I stared at those words.

I loved him too.

And this... this... whatever this was... only enhanced my love for him.

I convinced myself that this wasn't wrong!

How could something wrong feel so right?

I was making my son happy, which is the goal of every mother... every Mommy.

I struggled to text him too.

I love you too, son.

Another text.

I'm going to come in you Mommy.

Another text:

Just ride me a bit faster, Mommy.

Another text:

Please, Mommy!

I wanted to make him happy.

I wanted to get him off.

I wanted to feel his cum shoot inside my pussy.

So....

I began riding him faster, grabbing the back of my husband's seat slyly for support.

I didn't bounce on his cock like I desperately wanted to do, but I did move faster and did my expert move that always got my husband off, as I tightened my cunt muscles around his stiff dick.

And as it worked for my husband, it worked for my son... like father, like son, as I felt his cum suddenly fill my cunt.

I let out an uncontrollable moan, made worse by the fact that my head was leaning on the side of the chair just inches from my husband.

"You okay?" Alex asked again.

"Just really need to pee," I replied, as my son continued spewing inside me and I milked him for all I could.

"A couple of minutes," he promised.

"Okay," I replied, leaning up, before adding the double entendre, "much longer and I may explode."

"I'm doing the best I can," he said, knowing from years of travelling that when I say I have to pee... I have to pee.

My son began bucking his ass up, fucking me now, making me tremble and gasp, "Oh, God."

"The car stop is in two miles," Alex said, pointing to a sign.

"So close," I replied, again a double meaning to my words, as I desperately tried to come without screaming and before we reached the car stop.

Cory kept pumping his cock, not super-fast, or enough to make slapping sounds, but enough to have my orgasm building.

I could feel the rush rising in me, knowing the inevitable eruption was close, when I saw the one mile sign.

Urgency overwhelming me, I had to have an orgasm, I moved away from my husband, leaned back and began riding my son's cock, while moving my hand to my clit.

I was thankful the music was too loud for my husband to hear the sounds of sex behind him as I bounced on Cory's cock, desperate to orgasm.

I could see the car stop in the distance, closed my eyes and rode and rubbed... and erupted.

"God," I moaned loudly, holding onto the word long enough that I assumed my husband would know I was coming right behind him as I was unable to not open my mouth as my orgasm hit me like a thunderstorm, my cum gushing out of me and onto my son's cock and lap as I again grabbed the driver's seat and pulled up, my son's cock finally exiting my overheated pussy.
