Backseat Mommy: Jam-Packed With Cum

That morning, the second the shower was running, I got into Cory's bed, fished out his cock and began bobbing.

He groaned, as I woke him up the best possible way any man could be woken up... with head.

His cock was already hard; I love morning wood, and I bobbed hungrily, knowing time was of the essence. I wanted that first load for breakfast as I was determined to indeed get those four loads from him before I left for the hardest conversation in my life... the end of my marriage.

Yet, my guilt was overridden by my lust.

I loved my son.

I loved his cock.

I loved his cum.

I loved being his slut.

And I was going to find a way to continue this taboo, inappropriate and yet so right and natural feeling relationship at all costs... including the end of my marriage.

Thankfully, I learned that Cory, like every other guy I had ever been with, had a very quick morning trigger and I was swallowing his cum in a couple of minutes.

Once I had swallowed all his cum, I sat back up and said, "One done, three to go."

"You're serious?" he asked.

"I'm always serous when it comes to cum," I quipped back.

"Well that is the best wake-up call ever," he said, as the shower shut off.

"Yes, too bad we didn't have this relationship earlier," I said. "Cum is great for breakfast and the complexion."

"Fuck, how I regret my senior year and not bending you over the kitchen table and just making you mine," he sighed.

"Well, in that case, you owe me three hundred fucks," I said.

He laughed, "I'll write you an IOU."

"Just understand that I plan to collect on every single one," I winked, just as the bathroom door opened.

After a shower and breakfast, we were back on the highway.

I was back on my son's lap in a sundress and, of course, sans underwear and ready to have his cock back in me. In his hand was the bag he wouldn't let me see the night before.

As soon as we were back on the highway, Cory slyly opened the bag and pulled out what was obviously a butt plug, He handed it to me and then pulled out some lube.

Taking the unspoken cue, I lubed the big butt plug generously before I leaned forward and handed it to my son to put in my ass.

Cory smiled as he took it from me and slowly slid it in my ass. I clenched my teeth and grabbed the back of my husband's seat as it filled me.

Alex looked into the mirror and asked, "Uncomfortable already?"

"A little," I nodded, as the toy completely filled my ass. "Just trying to find the right spot."

"Only a few more hours," he reminded me.

Cory left me in that position, a butt plug in my ass as I said, "Yep, this wild adventure is almost over."

Alex nodded, "Then Cory, you start your next adventure."

I glanced back and saw he had fished out his already hard cock.

Cory replied, "I'm always up for a new adventure."

"That's the spirit," Alex nodded. "Live life to the fullest. If you want something just reach out and grab it."

The irony of his words were obvious, as Cory took that exact advice as he grabbed my hips and slowly lowered me on his thick dick and I was suddenly, surprisingly, being double penetrated as the three of us chatted.

I held my breath as his cock impaled me.

Mixed with the plug in my ass and I was suddenly feeling very full.

Alex added, "You see Sarah. Cory will be fine. I think we need to have an adventure too."

"The last couple of days have been quite the adventure," I replied tersely, both to make it clear I wasn't changing my mind about the trip and also because I was trying to get used to having two cocks in me simultaneously.

"But, I think...." Alex began.

"Alex," I said, my tone implying I wasn't having this conversation at the moment, "I have made up my mind. My son needs me and I will bend over backwards to make him happy."

Alex sighed heavily, as I sat on my son's lap with both his dick and the butt plug now lodged deep in me. I tried to relax, trying to get used to being so completely filled with two cocks while getting annoyed by my husband. I realized I wasn't being fair to him. We had spent a couple of months planning the fall road trip and Alex was super excited about it. Although I didn't love the idea of travelling for so long I went along with it. Yet now I couldn't.

Now I had to figure out who I really was. Yes, I would do anything to please my son, proven by the fact I had his dick in my cunt and a butt plug in my ass at the moment, but I also had to figure out the rest of my life.

Alex turned the radio up, and I figured I now had some time to get load two of four for the day.

Suddenly I felt a slight subtle vibrations in my ass. The butt plug was apparently a vibrating one. Instantly, pleasure began to build inside me as my son found a new way to pleasure me in this tiny confined space.

Although Cory had already shot his first load of the day down my throat, I hadn't yet come and as soon as the vibrations started I wanted to... no, I needed to.

I put my hands on his knees for balance, and began to ride his cock slowly, the sensation of riding his cock, mixed with the vibrations in my ass creating an instant euphoria.

And for a couple of minutes, I rode my son... nice and slow as I literally enjoyed the ride.

Then I felt the vibrations inside my ass get faster and more intense. To my surprise, there was almost no sound, which was impressive, although Alex was now singing to 'Sunglasses at Night' and I doubt he would have heard it even if it was loud.

The new vibrations instantly stimulated my entire body and added fuel to the flames of my slow burn orgasm. I wanted to milk his cum slowly, but I wasn't sure that was still possible.

I began to ride Cory's cock faster, my orgasm building, when the vibrations suddenly stopped. Cory grabbed my hips and held me and slowly lowered me onto his lap.

I sighed. I knew he planned to make me wait for my orgasm.

I knew that this made my orgasm more intense when it came (pun intended).

I also knew I didn't want to wait. I ground my ass on his cock to tell him as much, but as I figured he was going to let my burning flame flicker and fade before he fueled the flames again.

He handed me his phone.

It was a story called 'Mom's Stockings: A Cum Bucket'.

So I read it. Obviously, it turned me on as the mother sounded a lot like me once she accepted she loved her son as more than a son.

As I finished the story, Cory let go of my hips and took his phone back. The vibrations again started and I took that as permission to resume riding his thick shaft.

Again, I rode him for a couple of minutes slowly as I rekindled the flickering flame of lust.

Again, he turned the toy onto a higher, more intense speed.

Again, I began to ride him faster as the flames began to spread wildly.

Again, he grabbed my hips and pulled me down onto his lap... this time keeping the vibrating butt plug on high.

This would not get me off, but man it would tease me like crazy.

He again handed me his phone. This time it was a short article called 'More Moms Going Down to Ensure Grades Go Up'. It was about how some Japanese mothers were sucking their sons so they would be more motivated to study more.

Once done reading it, I handed it back to Cory who whispered, "Why didn't you do that for me?"

"I will throughout college," I replied, so horny I was willing to agree to almost anything, semantics and logistics irrelevant.

"That is something we need to make happen," Cory said.

"I agree," I nodded, as I ground my pussy on his cock, trying to hint it was time to fuck.

"You really need?" he asked.

I nodded.

He let go of my hips and I took that as permission to ride. I again put my hands on his knees and began to fuck myself on my son's big dick.

As soon as I started riding, I once again rekindled the flame down below.

The double stimulations made the pleasure escalate quickly and after a couple of minutes, as the flame burned like hell's kitchen I let out a much too loud moan.

Alex looked up, as I realized I moaned close to his head based on the angle I was in right then.

"Sorry, honey," I apologized quickly. "Three days back here and there just isn't a perfect position anymore."

"We're almost there," he said, as I thought to myself, 'So am I'.

"Thank God!" I said, the double meaning again used in my words.

I bit my lip so I wouldn't let out any more sounds that might give away the reality of what was happening right behind him.

"I hate to stop so early," he said. "But I have to pee."

"Okay," I nodded. "I could use a stretch too."

"I'll be pulling over in 4 miles," he said.

"Okay," I again responded, as I didn't want to say any more than I had to as I focused on the pleasure and the fact I had very limited time to get that second load milked from Cory's cock and my first, much needed, orgasm.

He resumed driving and I resumed riding.

Thankfully, I didn't need four miles, I needed one. The intense vibrations in my ass, mixed with the riding of my son's cock, and the fire finally became wildfire as my orgasm erupted through me.

When I started coming, Cory held my ass up, and kept fucking my pussy, even as I trembled with intense convulsions.

Another mile, my orgasm refusing to dissipate completely, I felt my pussy walls coated with my son's cum.

I just allowed the pleasure to continue its intense journey through me as Cory finished filling my pussy with his cum.

I felt the vibrator in my ass stop vibrating; I felt his cock slide out of me and instantly felt cum leak out of me; I felt his hand on my ass pull out the wide plug and even heard a slight pop sound as it exited me. Thankfully the music was too loud to hear it.

Cory handed me a wet nap and I wiped the extra cum that was leaking down my leg, as we reached the one mile turn off.

I sat on the edge of Cory's leg for the last mile, my orgasm finally coming to a reluctant end as I looked at Cory who was on his phone.

We made a pit stop. Alex went pee. I went pee and cleaned up.

Back in the car, we drove two hours in relative silence. Cory actually fell asleep and I read on my kindle.

We stopped for lunch and as we ate our food, I rubbed my son's crotch with my nylon-clad foot.

Alex said, as we were wrapping up, "Two more hours."

Cory nodded, looking at me slyly, "Two more."

I smiled, knowing he meant two more loads to shoot... my ass and the facial still to come... literally.

"Are you ready?" Alex asked.

"Definitely," Cory nodded, again saying two different things at once, as he rubbed my stocking-clad foot under the table.

"I wish I could go back to being in college again," Alex said.

"Me too," I nodded, thinking I actually planned to do just that.

Cory asked, "Were you two wild back then?"

Alex shrugged, but I joked, "Mostly wild orgies every night."

Alex was surprised but laughed, "Yes, that's the real way I met your mom."

I continued, "I'm sure you'll meet the perfect woman at college."

Cory asked, "What if I already have?"

Alex said, "I didn't know you even had a girlfriend."

"Oh, I've known her forever," Cory said. "I have just hidden my true feelings for years."

Alex gave the most ironic advice ever, as my heart skipped a beat, "Well, always tell the woman you love that you love her. Don't keep it a secret."

"At all costs?" Cory asked.

"Yes, at all costs," Alex said, looking at me with sweetness.

I agreed, "It's important to always go with what makes you happy."

"Okay," Cory nodded.

"Well enough love advice from old people," I said. "Let's get back on the road."

"This will be your last time backseat riding," Alex said.

God, he just kept saying such innocent things that meant something completely different to Cory and me. I nodded, "Yep, one last backseat ride. Think you can handle two more hours of me on your lap, Cory?"

"I think I'll be able to handle it," Cory smiled, as I moved my foot away and back into my heel.

"I'm sorry you've been stuck back there with your Mom sitting on your lap for three days," Alex said.

"It could be worse," Cory said.

I laughed, "Yes, I could weigh 300 pounds."

"Yes, that would be worse," Cory laughed.

Alex shook his head as he paid and we returned to the car.

Cory said, once we were alone, "You know I was talking about you."

"I thought so," I nodded.

"And that I want you in my life every day," he continued.

"I have to deal with some other things first, Cory," I said sincerely. "But I do plan to find a way to be closer to you."

"Mom, I love you," he said.

"I love you too, honey," I replied.

"No," he shook his head. "I mean I love love you."

"Oh," I said, realizing this had just crossed to a whole new level of complicated.

Alex came out and asked, "What you two talking about?"

Cory answered, "What is real love?"

"Heavy topic," Alex said, "and not a simple answer to what seems a simple question."

"Yes, love is different to every person," I said, as I tried to wrap my head around my son's words. Yes, I wanted to find a way to keep fucking him. Yes, I wanted to be his three hole cum slut. And yes, I couldn't imagine not living with or near him.

Yet... I didn't want to prevent him from finding true love, getting married and having kids.

Shit, this had gotten very, very messy... both figuratively and literally.

"Well, we are not getting any closer standing out here," Alex said.

"It's time for one final ride," I said, trying to push out the complicated and keep it simplistic. I had two hours left with his cock in the car and I planned to enjoy the entire two hours. The harsh reality and consequences of our actions would have to wait for another day.

Now, I was going to take it in the ass.

Once back in the car and back on the highway, I fished out his cock and stroked it to stiffness.

Once stiff, I pointed to the lube in a bag with my anal toy.

He handed it to me and I generously coated his once again hard cock.

I then positioned myself over his thick dick and lowered myself on it.

I took his entire cock slowly in my ass until I was sitting on his lap.

Then I just sat there, enjoying the feeling of being completely full.

Alex asked, about fifteen minutes later, "So, who is this girl you love?"

My eyes went big.

Cory answered, "Just someone I've known for a long time."

"Have I met her?" Alex asked.

"I think so," Cory answered.

"What's she look like?" Alex asked.

He described me. "Blonde hair, blue eyes, amazing legs and...."

Alex asked, as he looked into the rear-view mirror, "And what?"

"Big tits," Cory answered.

Alex shook his head, "I guess I shouldn't have asked."

I quipped, pretending to act offended, "Men."

Alex shrugged, "What are you complaining about, he pretty much described a younger version of you."

I barely could contain myself.

"So I should be flattered that you two are objectifying women?" I questioned, even as I wiggled my ass on my son.

Alex sighed, "That is not what we were doing."

"Blonde hair and blue eyes are the most stereotypical guy fantasy there is," I said.

"Yes, but...." Alex began.

"Throw in huge tits and you have the stereotypical blonde bimbo," I continued, ranting even though I didn't mean it at all.

Cory added, "Don't forget the great legs."

"Oh, how could I forget that? Your father is a leg man, thus why I'm always in nylons and heels. Are you a leg man too?" I asked, even though I knew the answer.

"That is probably your fault," Cory accused, playing along.

"My fault? My fault?" I questioned and repeated. "How is that possibly my fault?"

"Well, you've always walked around the house in short skirts and nylons," he said.

"In that case, I guess I should be flattered," I said, although still sounding angry. I then added, deciding to push the line even more, really getting into the fake feminist character I had just created, "And does your dream girl shave her vagina too?"

"Sarah!" Alex gasped.

I ignored him, as I looked at Cory. "Well, does she?"

"Hopefully," Cory nodded.

"And do you shave your balls for her?" I questioned, this time hinting at something he should do.

"For Christ's sake, Sarah," Alex said.

"What?" I questioned. "He's eighteen. He's an adult. You said he was ready to live on his own. At least he should know what a woman wants."

"So I should shave down there?" Cory asked sincerely.

"Of course," I nodded, "especially if you expect her to. Isn't that right, Alex?"

Alex answered, shaking his head, "I feel like I'm on a twisted version of Candid Camera."

"Any other advice you would like to receive?" I asked.

Alex interjected, "Don't say a word, Cory, it's a trap."

I laughed, "That is probably very good advice."

Alex turned the radio up, obviously done with our awkward conversation which meant Cory and I had some alone time, well as much alone time as you can have in a backseat on someone's lap.

I began to slowly grind my ass in a circular motion on my son's cock. This was going to be the last backseat fucking and I was going to enjoy the ride.

And for 50 miles I just slowly ground on his cock, enjoying the feeling of just being full, just enjoying the strange feeling of an unconditional secret love between me and my son.

"50 miles," Alex announced.

Oddly, this made me sad.

50 miles and this was over.

50 miles and I had to deal with the consequences of my actions.

50 miles and the only life I've known for a couple of decades is over.

50 miles and I had to have the conversation that had to take place, yet I feared completely.


50 miles to finish milking my son's third load of the day, this one in my ass.

I said, as I began to slowly ride my son's cock, "Thank God. I don't think I can last much longer."

Alex nodded, "I can only imagine how sore your ass must be. Mine is numb and I have my own seat."

"Oh, my ass feels great," I said back, as the lingering pleasure increased as soon as I began riding my son's cock.

Alex asked, "Really?"

"My legs are sore though," I answered, realizing what I said didn't make much sense to him.

"I imagine," he nodded, "being all cramped up back there. And Cory you'll probably need a week to recover."

Cory replied, "Hopefully not that long. I recover pretty quickly."

"Are you saying I'm fat?" I teased.

"What?" Alex asked, his eyes going big. "God, no."

"I'm just kidding," I laughed.

"Don't do that to me," Alex said, laughing back.
