Alex wouldn't ever eat me out, he said it was gross. So the idea of getting licked for the first time in a couple of decades, that having been done by my college roommate during a drunken night in our senior year, was very appealing.

"I thought you didn't like fish?" Alex puzzled.

"I do like one kind," my son answered, never taking his eyes off me.

"What kind is that?" Alex asked, oblivious to the naughty innuendo he was accidentally participating in.

I tried to change the topic, "Did you book us a hotel yet?"

Alex, never the planner, shrugged, "Nope."

Feeling a rush of exhilaration at chatting with my husband while simultaneously stroking my son's cock, I asked, "Shouldn't we call ahead?"

"There'll be space," Alex blindly believed.

"Okay," I shrugged, my focus on my son's cock.

"Looking forward to living on your own, Cory?" Alex asked.

"I'll have a roommate," he pointed out.

"Oh, right," Alex nodded, "are you looking forward to meeting him?"

"I guess," Cory responded, distracted by the way my fingers were tracing around his mushroom top.

"Hopefully you'll get along," Alex continued, trying to keep the dying conversation going.

I crooned, "Who couldn't love our sweet Cory?"

"Yes, I'm pretty much irresistible," he quipped.

"Is that a good thing?" my husband questioned.

"Sometimes," Cory answered.

We kept chatting for a few more minutes about trivialities until Alex turned the music back up.

"Need to change positions?" Cory asked.

"I think so," I nodded, never having stopped my stroking of his cock or staring at it.

He patted his lap, as if putting the decision this time completely in my hands (pun intended as I was still stroking his cock).

I paused to steady myself then I shifted around, my back to him, having changed hands to continue grasping his cock as I straddled it. I paused again, and then lowered myself onto my baby boy's big, hard, cunt-stretching cock. Oh my God did it feel good!

"You okay?" Alex asked, this becoming a recurring question.

"Oh, I just keep getting poked," I said, which was true, as Cory slyly moved his ass up and down.

"We'll try and reorganize everything tomorrow morning," Alex promised.

"Good idea," I nodded, as I tried not to moan.

"There must be a way to make this work."

Cory added, "I'm okay, Dad. I've gotten used to having Mom on top of me."

OMG! I thought to myself. His words were so blunt! Yet of course Alex didn't catch on... nor should he. Why would he think his son would be fucking his wife right behind him? His thoughts wouldn't go there even for an instant.

"Oh, I love this song," I said, when Starship's 'We Built This City' came on, wanting the music to be turned up, wanting a distraction from the irrepressible sounds I was about to make.

My husband obliged my request and not only cranked up the volume but began singing as well.

I leaned up close and began singing along with him as I offered my pussy to my son.

Thankfully my son didn't need to be instructed, as he began slowly fucking me.

Alex kept sharing looks with me, enjoying this revisiting of our 1980s duet singing as he sang the Mickey Thomas parts and I the Grace Slick parts, completely unaware that at this very moment his flesh and blood was fucking his wife.

And I just went with it... which made me not only a bad Mom for allowing my son to fuck me, but a bad wife as I got even more turned on, knowing I was cheating on him even though he was close enough we could have shared a kiss. Although I'm sure I couldn't have summoned enough self-control to carry that one off without moaning right into his mouth and giving everything away.

My orgasm was rising as the song was nearing its own climax and I screamed, "Oh fuck," when my son surprised me by sliding a finger in my ass.

"What's wrong?" Alex asked, slowing down the car.

"Leg cramp," I lied, falling back onto Cory's cock completely, and his finger pulled out of me as quickly as it had entered.

"Should I stop?" Alex asked.

"No, no worries," I said, as I began bouncing up and down on Cory's cock, "I'll just stretch it out."

"Poor Cory," Alex said, seeing my torso moving up and down as I allegedly stretched my leg, unaware of what I was really doing.

"I'm okay," Cory said, as his hands went to my hips.

"I'm not hurting you?" I asked, trying to play along.

He laughed, "No, it's all good."

"Definitely ready," I nodded, gazing at my son meaningfully, signaling to him that I was indeed looking forward to resuming what we'd just been doing.

"All right, next stop will be for the night," Alex announced.

"Sounds wonderful," I said, as Cory climbed back into the car.

Once we were all inside and back on the road, I fished out Cory's cock as Alex hoped, "Maybe we can find a hotel with a hot tub."

"That would be great," I agreed, my body sore from the long day of confined space and of course furtive fucking. I got Cory's cock out again, glad to feel it was still hard, and positioned it back at my wanton cunt.

Cory held my hips to keep me balanced as I lowered myself back onto his cock.

Once he was fully inside me, again I just sat on it, enjoying how full it made me feel. Then after a short while I began slowly grinding on him again, getting eager to get revved up again.

I just closed my eyes and enjoyed the slow build as, ironically, Billy Joel's 'We Didn't Start the Fire' rang through the car. The pulsing drums felt particularly helpful.

As my orgasm began building and I needed more, I decided to try a new position, so I leaned to my right as far as I could go, lifting my ass up, which made his cock slide out of me as I gestured at him.

Cory realized what I wanted. For him to roll onto his side and fuck me that way.

He repositioned himself, my head now leaning on the boxes and in plain view of my husband if he turned to his right and looked over his shoulder... which he did.

I smiled, "New position."

"I see," he nodded, thinking I was in search of comfort, not in search of getting off.

"Oh," I moaned ever so softly, as Cory's cock slid back into me. And then to explain myself I pointed out the window and announced, "Horses."

"Yep," Alex nodded, as he tried to sing along with Billy Joel.

Meanwhile my fire was now flaming as Cody slowly slid his cock in and out of me.

I needed to reach another orgasm and I needed it soon. The starts and stops had driven me crazy and I was more desperate than ever for liftoff.

I wiggled my ass, signaling I wanted him to ream me faster.

Thankfully Cory understood and began pumping in and out of me with renewed vigour as a new song began, again an ironic one, Duran Duran's 'Hungry like the Wolf'.

And I was indeed hungry.

Alex turned back to us and said, "Ten minutes,"

"Thank God," I replied, both because even when he turned he could only see my head, but also because now we all needed to get out of here before the scent of my sin, which would very soon be permeating the car, wafted into my husband's nose.

"Your cheeks are really red, Sarah," Alex said, looking at me worriedly.

"It's really hot in here I guess," I replied, a viable excuse on this hot summer evening.

Once Cory was done cleaning up his Mommy, I shifted back onto his lap and slumped back against him, utterly exhausted.

He whispered in my ear, "I love you, Mommy."

I wiggled my ass in response, too tired to speak, but I did reach back to caress his cheek for a few affectionate moments.

Eventually we arrived in the town, and we found a hotel pretty easily. It even had a pool with a hot tub! Alex booked two rooms, and after dinner we all went for a dip.

While Alex went to hit the sauna Cory and I slipped into the hot tub where he said, "So Mommy, once Dad is asleep I want you to come to my room."

"Really?" I asked, acting coy. "I can't imagine why."

"And I expect you to be wearing thigh highs," he added, addressing me strongly and firmly, which I found fucking sexy.

"How do you even know I own thigh highs?" I teased.

"You wear them all the time," he pointed out before adding, "and often your skirts are short enough to give me glimpses of your lace tops."

"You like my stockings?" I asked, something his father also loved.

"How couldn't I?" he asked, "you wear them every day... I've been perving on them for years."

"Really?" I asked, surprised by this information.

"I even made Karen wear them for me," he added.

"Then you're just like your father."

"He likes them too?"

"He especially enjoys foot jobs when I'm wearing them," I revealed.

"That I've never had done to me," Cory said wistfully.

"Mmmmmmm," I purred promisingly, my foot going to his cock.

"I can't wait to fuck you in a bed," he said bluntly.

"Me too," I nodded, "but I'm not sure I should sneak out of our room."

"Once he gets to snoring nothing will wake him up," Cory pointed out, which was true.

"But still..." I said.

"I'm not asking, Mom," he said, "I'm telling you what you're going to do for me."

"You are, are you?" I questioned coyly.

"I am, Mother," he nodded, "tonight you're mine."

"I'm your what?" I pressed, as my foot continued pressing against his stiff cock.

"You're my Mommy-slut," he answered firmly.

"Fuck is that hot," I moaned, totally turned on.

Alex came out of the sauna and told us, "I'm going upstairs."

"I'll join you soon," I nodded, thinking that first maybe my new lover and I could have some fun in the empty pool.

"Okay," Alex nodded, leaving us alone.

As soon as he was gone, I asked, "So: you ever fucked in a pool?"

"Actually, I have," he answered.

"Slut," I joked.

He shrugged, "Never did it on a waterslide though."

"Hmmmmmmmm," I purred. "We would be pretty isolated up there. It's enclosed."

"Let's go," he nodded, climbing out of the hot tub.

I followed him up the stairs.

Once we were at the top of the waterslide he ordered me, "On your knees, Mommy."
