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.


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.
