Backseat Mommy: Lustful 3-Hole Slut

In the car I pondered how to have the conversation I needed to have with my husband.

The past three days had been an escape from reality... as bizarre as that sounds.

Fucking my son over and over while my husband was oblivious to the entire thing was exhilarating and life-altering... but now I had to deal with the consequences of my reckless behavior. My actions of the past three days had awakened my sexual libido and made me realize I didn't love my husband as a husband.

Yes, he was a great man.

Yes, I loved him as a man.

I just didn't love him as a lover.

We drove in silence for fifteen minutes, as I tried to figure out what to say. Usually, casual conversation was my strength, while Alex could drive for hours without saying a word other than to sing a tune or ask me musical trivia. He loved asking me who sang the song that was playing. I almost never knew. He would then give me a brief history of the band.

Yet, it was obvious, at least to me, that the divide in our marriage was right there... within the open space between our seats.

To my ashtonishment, it was Alex who broke the ice out of nowhere. "So how long have you been fucking our son?"

I imagine my face paled as I realized in moments that he knew.

How long had he known?

"A week, a month, a year?" He listed as he drove. He didn't look at me. His tone was not one of anger or shock, oddly enough.

"Just during this trip," I admitted.

"Did you enjoy it?" He asked.

What a tough question. The answer was obvious: yes. But admitting the truth could hurt him even more than I already had. Yet, I couldn't lie. He deserved the truth. "Yes."

"And is that why you don't want to do everything we had planned for the past eight months?" He continued.

"Yes," I again admitted, sticking to one word answers.

"And now what?" He asked.

"The truth?" I asked.

He looked at me for the first time, ironically. "No, keep lying to me."

There it was finally in his tone and in his eyes... the hurt I had caused him.

"I'm sorry, Alex," I said instead.

"For what?" He asked. "Fucking our son in the back seat or fucking our son in the bed I was in?"

I hoped he only knew about those two times, somehow that made it a little less bad.

Yet, I tried to explain. "I have no idea how it happened. But once it did, it awakened a side of me I've always kept under wraps. And after that, I couldn't control myself."

He sighed.

The gap between us widened.

"Have you cheated on me before?" He asked after a long silence.

"No," I answered. "I never even considered cheating."

Again silence.

Then he sighed.

More silence.

Then surprisingly he said, "I'm sorry too."

"For what?" I asked, surprised by his apology. "You did nothing wrong."

"I've been cheating on you for a long time," he confessed.

"What?" I asked, shocked.

"I've been lying to you and to myself for years," he continued.

"With who?" I asked, suddenly jealous even though I had cheated too... with my own son.

"Gary," he revealed.

"Gary," I repeated, stunned, hearing the name, but not comprehending the scope of his words. Then as realization hit, I stammered, "Do you mean your partner Gary?"

"Yeah," he nodded, looking straight ahead at the open road.

"You're gay?" I asked, my head spinning with incomprehension, unable to absorb where this was going even though the answer was obvious. The person he had named was a male.

"Yes," he admitted, his turn to fall back on one word answers.

"Wow!" I breathed, before adding, "We really don't communicate well."

He laughed. "I've wanted to tell you for a long time, but I couldn't get up the courage. I also didn't want to shatter our family."

"Well, I may have beat you to that," I replied.

"But with Karen overseas traveling and our son starting college, plus the fact that my wife is fucking him, I figured it was time to tell you the truth," he said.

"We've both been living lies," I said. "I've always wanted you to be more forceful and more dominant."

He chuckled, "And I wanted the same thing. I'm the bottom."

"Of course you are," I smiled, that suddenly making complete sense considering our sexual history together.

"What's that supposed to mean?" He retorted, oddly offended for the first time during this surreal conversation of revelations.

"I didn't mean it rudely. I'm submissive too, which is perhaps why we struggled so hard to find any heat in the bedroom," I explained.

"And I'd rather be fucked than do the fucking," he pointed out bluntly as a joke.

Hearing him talk so bluntly was more surreal than all that had transpired. In over twenty years together we had never spoken so frankly together.

"Man, this conversation could have saved a lot of years for both of us," I laughed, trying to imagine him taking it up the ass.

"It didn't stop me," he joked.

"Well, we do have one thing in common," I smiled, shaking my head... even now, it was just sinking in that he had been cheating on me for years. This would have offended me greatly a couple of weeks ago... but now it just released me from the guilt that had been eating inside me for the last several days.

"What is that?"

"We both love cock up our ass," I said crudely with a wicked smile... somehow sharing that dirty little secret with each other was helping us both to release some of our guilt, and adding in the fact that he wasn't judging me for my incestuous transgression was liberating me... was liberating us.

He laughed, "That we do. We both also love sucking cock."

I agreed, "True. Although I can't fathom you sucking dick."

"I'm pretty good at it," he said.

"Me too," I countered.

"True enough," he nodded, having been on the receiving end of many of my epic blow jobs.

Then it hit me. Did I turn him gay? I asked, "When did you realize you liked dick in your mouth and ass?"

"It started with online porn and then a trip with Gary that took us to a male sauna and ended with me sucking his cock," he answered.

"So I didn't turn you gay?" I asked, suddenly feeling insecure.

He laughed. "God, no. You were likely kept me thinking I was straight a lot longer."

"Thank God," I sighed, ironically happy that my husband was gay and it wasn't because of me. I then joked, "So you've been faking it all this time?"

"No," he said, seriously. "I still enjoy sex with you, especially oral sex, but I enjoy getting fucked even more."

"I still enjoy sex with you too," I agreed.

"So, what now?" He asked.

"I don't know," I admitted. I felt we were making headway through this morass, but I was even more confused now than I had been before we began this .conversation.

"Do you plan to keep fucking our son?" He asked.

"I don't know," I repeated, the generic non-committal answer. My body screamed yes, my brain said maybe.

"I'm okay with it," he offered, surprising me again.

"What? Really?" I asked.

"Yeah," he nodded, "he can give you what I can't."

"But it's incest," I pointed out.

He paused for a long moment. Gathering his courage? "Want to know another shocking secret?" he finally asked.

"More shocking than you love taking it in the ass?" I bluntly questioned.

"Believe it or not... yes," he nodded.

"This I'm dying to hear," I said, curious as hell... but also a bit nervous.

"I lost my virginity to Katherine," he revealed, "In her pussy and her ass."

My eyes went big.

My mouth dropped open.

"Your older sister, Katherine?" I asked.

"Yep," he nodded.

"You've stuck it up the ass of your older sister?" I questioned incredulously. This seemed even less fathomable than him being gay or me committing incest.

"The one and only," he nodded.

"Your condescending sister who treats me like a whore?" I pressed, At a loss to even picture such a thing.

"She used to be a lot wilder," he explained.

"So it seems," I said, still trying to envision a time when my bitch of a sister-in-law was a skank. That said, it did make me kind of happy. "So that is why you didn't freak out when you figured out I was fucking our son?"

"I was shocked at first. But it instantly made me remember losing my virginity to my sister at the lake, and how incest brought my sister and I me closer for a while and, well," he shrugged, "I figure he may be giving you some things that I never could."

"Oh," I said.

"Plus, I realized then that you and I are the same thing as each other."

"Sluts?" I joked.

"Well, fucking our son in the back seat of the car while your husband drives is pretty slutty," he joked back.

"So is taking it in the ass in a public washroom," I added.

"So is taking it in the ass at a company picnic while your wife is right outside the rest room visiting with other wives," he countered.

"Okay, we are both sluts," I concluded.

"And yet, we've now both discovered what we are and what we want," he continued, "to be sexually liberated."

"From society's standards?" I questioned.

"Yes, gay sex is far more common than people think and so is incest," he added.

"Is it?"

"Sure," he nodded, "it's just the one taboo still not talked about, although one day it might be. Christ, even transgender people are out and popular since the Caitlyn Jenner thing. Incest really is the only taboo left."

I added, "Maybe we need the Kardashians to announce they eat each other's cunts."

"That would make a great episode," he laughed.

"It can be one of those very special episodes," I joked.

He laughed again as he pulled into the hotel parking lot.

Our marriage was over, and here we were getting along together better than we'd done in years. Go figure!

We decided we would spend one more week together. He fucked me one last time. We went together to a sex shop, bought a strap-on and I fucked him with it... twice... a special treat for him that had suddenly popped into my head after learning he liked it in the ass.

I kept the strap-on in case I ever got to use it again... enjoying the power that comes from being the one wearing the cock... in essence in giving rather than receiving.

We separated with no regrets.

We split our assets and went our own ways.

Alex decided to go to Europe for a couple of months and I, unsure what to do, headed back to Cory's college feeling both liberated but yet suddenly alone. Alex and I had been together for over two decades... and he had been more than just a lover... but a listener... a comforter (especially when I lost my father)... a companion.

Other than seeing my son, I really had no idea what now lie ahead.

A month ago the rest of my life had been planned out. At first that excited me... the destination of my future mapped out.

Now... the map was empty... the journey unclear... and although that also excited me, it also scared the shit out of me.

I loved my son.

I loved sex with my son.

But that was raw passion over a few wild, kinky days. The reality was that the real world now awaited me, awaited us, and I was no longer sure what that meant.

Sex was sex and it had been fucking amazing.

But life was a lot more complicated.

So I arrived at Cory's dorm riddled with anxiety. I felt kind of like Julia Robert's character in 'Notting Hill' as I arrived. I had texted him that I was coming, but he knew nothing about what had transpired between his father and me.

We had done some naughty texting, but not being in the same place to act on it made it more anti-climactic (pun intended) than satisfying.

I assumed we would have some great sex when I arrived and I was right.

As soon as I arrived, I texted:

I'm here.

He responded:

Meet me at Thurber Hall, room 432. NOW!!! I responded, being cheeky and submissive at the same time:

Yes, Master!!!

My cunt was instantly wet. I wanted his cock back in me again. I hadn't been so horny for cock since college (if you ignore our 3 day backseat fuckfest).

I was dressed in a sexy sundress that barely hid my thigh highs... and, of course, I was sans bra or panties.

I had to ask three people how to get where I was going, but eventually I found the building and, with my feet sore (shouldn't have worn four inch heels to search for a building... but I wanted to look completely hot and sexy for my son). I took the elevator, gradually realizing that he was meeting me in a classroom.

I got off the elevator and headed to room 432.

It was a handicapped bathroom.

I stopped and then I smiled. That brat.

I went to open the door, but it was locked.

I knocked.

"Who is it?" My son asked from the other side of the door.

"Your slut," I answered, after looking around to make sure no one was around to hear my answer.

He unlocked the door and I walked in. I smiled playfully, "You really went all out on the decor."

"I wasn't sure what the plan was, or how I was introducing you, but regardless of either of those issues, I wanted to fuck you first," he answered.

"Good," I nodded, slipping out of my heels and dropping to my knees. "I've been craving this big dick ever since you last coated my face in your dorm room."

"And I've been saving up a pretty full load," he replied, as I fished out his cock, already hard.

"You haven't fucked any coed sluts yet?" I questioned, as I stroked his thick shaft.

"I didn't say that," he said. "I just said I've been saving this load."

"Slut," I teased, before taking his cock in my mouth. As I did, I felt a strange sense of jealousy at the idea of some college skank sucking and fucking this same dick that I was sucking. This is my dick. I am his slut. I bobbed hungrily, gently reminding him who was the best cock sucker.

"Oh yeah, I missed those cock sucking lips," he groaned, as I devoured his entire cock like a porn star.

I moaned on his cock in response.

"Yes, Mom, the first load gets deposited in that sexy mouth of yours," he promised.

I responded, taking his cock out of my mouth, "I hope you have enough loads stored up in these balls to fill all three of Mommy's neglected holes."

"At least twice," he bragged, as he grabbed my head and shoved my mouth back on his cock and began thrusting.

'Six loads!' I thought to myself. That would be a dream come true... pun definitely implied.

"Oh yeah, I plan to fuck you all day and night, Mommy-slut," he said, as I resumed bobbing. "The schedule for today is a marathon incest session."

I couldn't help but smile as he resumed fucking my face. We used to have many marathon nights back at home. Although they only involved things like watching all the Back to the Future movies, or all the Star Wars movies or, the craziest, all three Lord of the Rings extended version movies.

The mixture of my warm mouth and his fast pumping was the perfect trigger for his quick first load to explode in my mouth. There was no warning other than a slight swelling in his dick, then an animalistic grunt as his cum exploded in my mouth like a water hose.

I swallowed most of it, as he kept fucking my face... although a little of his cum did leak out of my mouth.

"Fuck, I love having my own Mom cum deposit handy," he groaned, as he finally pulled out.

"And I like having my own gun, always hard, always loaded, always ready to shoot me," I smiled, still on my knees as I scooped a little cum off the side of my mouth.

"So what are your plans now that you and Dad are done?" he asked.

"Today, I plan to take five more loads," I said, reaching for his still hard cock. "Tomorrow, I'll take some more and then figure out what the hell I'm going to do with my life."

He said, now soft and tender, "I found a few places in the area that are for rent."

"You did, did you?" I asked, slowly stroking his cock. "Do you want Mommy close to you?"

"I insist that my Mommy fuck slut be close to me and that she be available at a moment's notice," he corrected, sounding so hot when he was so dominant.

"Well then," I said, licking his shaft briefly, unable not to enjoy this beautiful cock I'd co-created, "since you are my Master and I am your three hole cum deposit, I guess the first part of my future plan has already been decided."

"Good, because we have a 7PM meeting with a realtor to go look at three places," he said, as he pulled me up and kissed me.

The kiss was tender at first. Definitely not of a mother and son... but of lovers. I felt my heart melting.

It got more passionate after a couple of minutes before I finally broke the kiss abruptly, horny as hell, and asked, "Are you going to fuck me or what?"

"I don't know," he said, "I only have twenty minutes until my last class of the day."

"You're not leaving your slut alone for a couple of hours with so many young dicks, are you?" I teased, returning to stroking his cock.

"You only fuck who I tell you to, is that clear?" he clarified firmly.

"Yes, Master," I smiled, "I was just teasing. Your cock is more than enough for me."

"Good," he nodded, as he lifted up my dress, bent me over the sink and slid his cock easily inside my burning inferno.

"Oh yes, baby," I moaned, as he began fucking me hard.

"God, I love your hot cunt," he said.

"And my hot cunt loves your big, hard dick," I responded, loving how aggressive he was with me. He knew how to fuck a woman... he understood that underneath the conservative nature of this woman was a cum hungry slut just dying to be used as such.

"Then let's let them get reacquainted," he said, as he grabbed my hips and thoroughly pounded me like the wanton slut I had become.

"Oh yesssss, son," I moaned. "Use Mommy as your fuck slut."

"You love being your son's personal cum bucket, don't you?" he asked, never slowing down his complete pilfering of my box.

"Can it please be my twenty-four-seven job?" I moaned, my orgasm quickly accelerating from his big dick, hard deep thrusts and his nasty talk.

"Think you can handle a half dozen loads a day?" he teased, as his finger slid to my asshole.

"I'm not sure I can live without that many," I responded, although I wasn't sure I could keep up with him, truth be told... but I'd die trying... I mean, what a way to go... FUCKED TO DEATH.

"You will only fuck who I tell you to fuck," he reminded me.

"Yes, Master," I moaned, the idea of him controlling my body and whatever he made me do would only enhance my lust and power my growing orgasm even more.
