Backseat Mommy: Ass Fucked

I woke up the next morning washed full of guilt.

I had willingly fucked my son in the backseat of the car while my husband drove.

I had snuck out of our hotel room while my husband slept and went into my son's room to fuck him again.

With guilt controlling me, and a tingle in my pussy at reminiscing about yesterday and last night, I climbed under the sheets and took Alex's cock in my mouth. I had only woken him up like this once before, the day after our wedding, and he had joked for years since (decades actually) that I wake him up properly.

Feeling his completely flaccid cock slowly grow in my mouth was always a turn-on... I loved the power of making a cock get hard with my mouth.

I heard soft whimpers and wondered if he was having a sex dream or was waking up.

After a couple of minutes, he groaned, "Oh my, Sarah, what's gotten into you?"

The true answer was 'Your son's big dick', but that didn't seem like the right answer to give, so I purred, "Just hungry for a morning snack."

"I'm not complaining," he groaned, as I slowly bobbed up and down as his cock became fully erect in my mouth.

As was always the case when we had morning sex, which was rare, he didn't last long quickly spewing in my mouth. I swallowed the entire load and asked, "Wanna join me in the shower?"

"Sure," he nodded, with a big smile on his face.

He returned the favour in the shower, using the removable shower head.

We met Cory downstairs for breakfast and the moment I saw him I already knew I was going to fuck him again. I couldn't explain it other than undeniable lust. The sex yesterday had been exhilarating whether in the backseat with the potential of getting caught or in the hotel with the intense sex of having my son take control of me.

I had no idea what he had in mind for me today... but my pussy was already wet with anticipation, the thong I was wearing, likely temporarily, was already damp.

Alex asked, as we ate, "You sure you guys can do another day squeezed back there together?"

I responded, "It is a little tight," which could be taken as I meant it, just a true statement, or as sexual innuendo as Cory took it.

"True, but the longer we go the looser it gets," he quipped, making me instantly blush.

"That is true," I laughed, trying to hide the blush.

"Well, we are over one-third there," Alex said, excited to end the trip and spend some quality one-on-one time with his suddenly amorous wife.

We were on the road in ten minutes, me again on my son's lap, when he texted me:

C: Thigh highs again?

I responded back:

M: Easy access for your big dick.

He responded:

C: No regrets?

I texted back:

M: Not doing it sooner.

I felt like a high schooler again... waiting for my boyfriend to make the inevitable move.

A chill went up my spine as I felt his hands on my hips.

A chill went up my spine when he lifted me up.

I glanced at my husband, who was focused on the road and the down pouring of rain.

I felt him pull my thong aside and slowly lower me on his fully erect cock.

He texted me, once I was sitting entirely on his dick:

C: Let's just sit like this for a while.

I nodded.

And for the next hour I sat on my son's cock. I wanted to ride on it, or grind on it, yet I just sat on it. I tried to read a book, but that was useless. Instead, I just let the longest tease of my life drive me wild.

When the rain finally stopped, Alex said, "How you guys doing back there?"

"Just making the most out of a tight spot," my son quipped.

"Yes, it seems even a bit tighter back here than it was yesterday," I said back.

"Should we stop?" Alex asked. "There is a truck stop in about fifteen minutes."

"No, we should try to make it until at least lunch," I said, hoping to have an orgasm or two before then.

"Yes, I can last as long as necessary, Dad," Cory added.

I was worried that meant he wasn't planning to fuck me during this long, dreary drive. I added, really talking only to my son, referring to blue balls, "Don't last too long. You'll go all numb."

"Oh, I have incredible stamina," Cory responded back.

"Okay, well, let me know if you need a break," Alex said, just as it started to downpour again.

"Sounds good, honey," I agreed, before adding, being the nagging driver wife, I usually was when I was in the front seat, "Focus on the road."

"Nothing else to do," he said.

I began slowly grinding on my son's cock.

I was surprised when he grabbed my hips and held me in place.

I grabbed my phone and texted him:

M: Why? Mommy needs it now!!!

He moved one hand away and then showed me his phone:

C: All good things CUM to those who wait... and obey!

I sighed. I was horny as hell and wanted it now!

Yet, instead, I again just sat there like a firefighter with a hose but no water.

Another half hour passed, although it seemed like three, before Cory put his hands back on my hips.

I thought to myself 'About time'.

I prepared myself for him to start slowly fucking me, but was surprised again as I felt his finger probe my asshole.

'He isn't seriously thinking of fucking my ass?' I thought to myself. Although I hadn't had anal sex since college, Alex actually rejecting me when I offered him my backdoor during the third day of our honeymoon in Niagara Falls, I did fuck myself in the ass on occasion when home alone... my favourite way to get off being to double penetrate myself... usually fantasizing about being dp'd in real life... a fantasy that I had never fulfilled.

I tried to relax and allow his finger in, having had my much bigger vibrating butt plug in there just last week. Yet, without lube and at this angle it was not going to be as pleasant.

His finger teased for a couple of minutes, but didn't enter, before he lowered me back on his throbbing cock.

He then texted me, as my pussy was again full:

C: Put your phone on mute.

I did.

He texted again and we started a lengthy texting conversation:

C: Have you ever been fucked in the ass?

I pondered whether I should tell the truth. I figured no reason to be prudish or conservative now.

I responded:

M: Not since college.

M: With a real cock anyway!

C: Dad doesn't fuck your sweet ass?

M: Your father thinks it's disgusting.

C: I don't know how we have the same DNA!

M: I'm beginning to wonder if you were not switched at birth.

M: LOL.

C: So when was the last time you had something in that fine ass of yours?

M: Last week.

C: Details.

M: It was awesome!

C: Don't make me spank you.

M: <Blush> Is that supposed to be a threat.

Alex didn't spank me either, another thing I really liked back in college. What I really loved was slaps on my clit when I was close, another thing I did to myself when home alone and using my toys on my two holes.

C: Oh, Mom, to have only known this earlier.

Wanting to text nasty... to keep him hard and hopefully get him wanting me to ride him, I asked blunt naughty questions.

M: Why, would you bend me over the kitchen table and slam that sausage in my asshole?

M: Or put me over your knee and spank my bare bottom for being such a bad Mommy-slut and not offering my cock sucking mouth, burning hot cunt and tight asshole for my son to deposit his sweet cum inside?

C: Holy shit, Mom. I would love to hear those words actually coming out of your mouth.

M: And I'd love that cock of yours slamming in my shit hole as you fucked me so hard I declared to the entire world my son was a dirty Mother-fucker.

C: Ride me, slut, but keep texting me.

The words I had been dying to hear... or read. I quickly obeyed, moving my one hand on the top of my husband's seat, while keeping my phone in the other. I slowly began moving up and down, glancing up to see the rain was coming down even harder now. There was no way Alex would be paying attention at all to what was happening directly behind him.

C: Nice and slow, Mom.

M: God, I just want you to bend me over and take control of me right here!

C: You're such a slut, Mom.

M: Your slut, baby.

C: Forever!!!

Reading that word.

One simple word.

I realized that this could be more than a 3 day backseat stand... it could be so much more.

M: You want to fuck Mommy for more than just during this road trip?

C: Mom, I own you now. I plan to have you come visit often and shoot so many loads of cum in you that you will be cum-bloated.

M: No such thing as too much cum.

C: Is that a challenge?

M: A fact!

C: You have experience with this?

M: More fantasy than reality.

C: So what is your fantasy?

I pondered this. I could probably list a dozen. I want to be with a woman. I want to be double penetrated by two cocks. I would like to be the centerpiece of a gangbang or a train.

M: I have quite a few.

M: U?

C: Tell me.

I continued slowly riding my son, as I listed just some of my fantasies.

M: I would like to be with a woman.

M: I would like to be double penetrated.

M: I would like to be gangbanged.

M: I would like to go to a glory hole and suck cock after cock.

M: I would like to be triple-penetrated.

M: I would like to be with a she-male.

C: A she-male.

M: A cock and tits... that is the best of both worlds.

C: LOL.

My pussy was on fire as I listed my many naughty fantasies to my son. I wanted to come... no, I needed to come.

M: Do you want to watch Mommy eat cunt?

M: Get double penetrated?

M: Gangbanged?

M: Fisted?

M: Have a cum bath?

C: Oh God, so hot.

He grabbed my hips and began pumping furiously into my wanton cunt. Knowing he was close to coming, I decided to keep texting nasty.

M: Do you want to fuck Mommy's ass?

M: Pound the living shit out of Mommy.

M: Ream her butt.

M: Cleanse my asshole with your full load of cum.

I felt his cum erupt inside me as my own orgasm built.

He pulled me back onto his cock and held me there, preventing my orgasm from erupting.

C: No coming for you yet, Mommy.

I was completely frustrated. I was so close and desperate to come.

M: Please!!!

C: No! Mommy-pets only come when they get permission.

M: I'll do anything.

C: Anything???

M: Mommy is your complete obedient cum slut, baby.

C: Anything has a pretty wide scope.

M: Yes, baby it does.

C: You'd eat cunt for me?

M: YES!!!

C: You'd fuck me and a buddy simultaneously?

The idea of fucking him and his good friend Calvin immediately popped into my head. Somehow years of fantasies, of reading online literotica and watching porn wasn't enough. I wanted to live out my many slutty fantasies... I wanted to be the star of my own porno.

M: YES, please!!!!!!!!!!!!!!!!!!!!!!!

C: What about coming to my frat house, if I join one, and being a cum bucket for the entire fraternity?

M: OH MY GOD!!! I might come just by sitting here.


M: Does my son want me to be gangbanged?


C: I'm asking the questions here. But yes, helping make your fantasies come true would be both a major turn-on and gratifying as well.

So desperate to come... so desperate to impress him... so in love with him as both a son and a lover... I used a word that would forever change our relationship.

M: I will obey whatever you order me to do, Master.

C: MASTER!!! I like that.

M: I mean it, Master. I will obey you without hesitation or limitations.

C: What about Dad? Would you scream 'Your son is reaming my asshole?'

Aye! The rub. I was so overwhelmed with lust that I briefly forgot I was not only married, but my loving husband was inches away. Guilt immediately came back, which was ironic considering all I had already done.

M:???

M: I love your father.

M: And I love you.

C: I love him too.

C: But, this is real.

Real....

Was it?

It was raw.

It was intense.

It was taboo.

But... was I willing to end my marriage to be with my son?

Reality came crashing in hard.

As I pondered this reality, Alex spoke for the first time in a long time, "Pulling over in three miles. I need to pee, we need gas and we should likely have lunch."

With my orgasm suppressed by a sudden guilt, I agreed, "I could pee and eat too."

Cory added, "Me three."

I remained on his cock until Alex was pulling off the highway. I slowly got off his cock and felt his cum and my wetness leak out of me and down my leg.

As I smelled my sex, strong and undeniable, I was thankful for my husband's anosmia... his inability to perceive odor (which was caused by chronic meningitis as a teenager).

I moved my thong back over my leaking pussy and moved to my son's right leg.

He texted me:

C: We will continue this conversation later.

C: PS: I plan to plug that ass sometime today.

We didn't say anything, as we both contemplated the one flaw with this intense sex... my husband and his dad.

I love Alex. He is a good man. A caring husband and a great provider.

Yet, he had never really been able to understand my sexual desires or even attempt to fulfill them. For years I had just accepted that this was the way it was. Yet, yesterday's raw carnal sex had awakened the sleeping slut in me, and I had no intention of putting it back to slumber.

I decided to text back, willing to risk everything for more of that sexual intensity, my cunt and ass overruling my moral code... or what was left of it.

M: You better. My asshole is tingling with anticipation for that big thick cock of yours.

C: You better find some lube. I'm reaming that asshole first chance I get.

As the car pulled into a rather large parking lot with a few restaurants, gas stations and more, I pondered if we could somehow slip away to a bathroom that was inconspicuous.

And where the hell would I get lube?

As soon as the car stopped, I got out. I looked around not for a bathroom, even though I had to pee, not for a restaurant, even though I was hungry, but for a place that would sell anal lube... which seemed unlikely.

Alex said, "Let's eat first."

"Well, let's go to the washroom first," I countered.

"Okay," he nodded. "Then let's meet at the family restaurant. I need to have some real food."

"Sounds good," I nodded.

I headed to the bathroom. I was sitting on the stall peeing when I got a text.

C: I just googled anal lube alternatives and apparently coconut oil is one that works well.

I figured that was slightly easier to find, but not a lot. I quipped back:

M: Shoot, I just used the last of it this morning.

C: I'm going on the prowl for coconut oil or lube.

M: Happy hunting!

M: Master!

I finished peeing and went to meet my husband.

He asked, "Where is Cory?"

"I thought he was with you," I lied.

"I should text him," he said.

"Oh, let him be. He is capable of fending for himself," I said.

"True enough," he nodded. "Plus, that will give us some alone time."

"I'm not sucking you off in the restaurant," I quipped, before adding, "although if you can find a discreet location I wouldn't mind a quickie."

"You are suddenly insatiable," he said, shaking his head.

"That sounds like a great name for a porn movie," I joked, as he found an open table.

We had lunch and chatted about our brief road trip while we waited for our condo to be ready.

We were just finishing up, when Cory texted:

C: Circle C family bathroom now!

"Is it Cory?" Alex asked.

"Yes," I nodded. "He needs some money. Apparently where he is eating doesn't take credit cards."

"Oh, I can go and help him," Alex said.

"No, no," I said, trying not to look too eager. "You pay the bill here, get some snacks for the drive... I want some licorice, and fuel up the vehicle."

"Yes, drill sergeant," he joked, always teasing me about my planned itinerary.

"You better be ready to be a full time drill sergeant once we drop Cory off tomorrow," I quipped back, before I kissed him and walked away.

I texted:

M: On my way, Master.

C: Hurry up slut,

C: Time for your butt!

I laughed at his terrible rhyme and tried my own as I saw the Circle C a couple of buildings down.

M: You're no Eminem.

M: But you can have my back end.

C: Okay, that was better, LOL

C: Now hurry up!!!

I walked double fast, almost running... knowing time was of the essence.

Reaching the bathroom, it was locked. I knocked.

The door opened and I quickly went inside before it closed again.

"Bend over the sink," Cory ordered, taking control quickly.

"Yes, Master," I purred, turned on by both his strong persona and what we were apparently about to do.

Once I was bent over, I saw lube in his hand. I asked, "You found lube?"

"Believe it or not, yes," he nodded, as he tugged my thong down, and poured some on his cock and then down my ass cheeks.

A chill of adrenaline coursed through me at the reality I was about to be ass fucked. I had fantasized about it for years, tried to replicate it for years, yet nothing beats the real thing.

I felt his cock rub up and down my ass cheeks and then felt his cock teasing my asshole.

I moaned, "Just slide it in, baby. My ass was made for your cock."

He laughed, "Who would have thought I would ever hear those words from you two days ago?"

"Yesterday morning evennnnnn," I pointed out, as his cock broke the invisible barrier that prevented such outside violations.

"So tight," he groaned, as his cock moved inside me, slow like a turtle.
