I sat and let the pee run out of me into the motel toilet. It was the early hours in the morning and I was doing a body survey. I had pinch marks and hickeys all over my body. My nipples looked like they had been pulled so many times they might never return to their former shape. My mom's cunt was so sore, the toilet paper gave it a little sting when I wiped. I stood up and flushed, and looked in the mirror.

My God, Jennifer, you are a filthy slut!

It was the happiest I had felt in weeks.

My phone was on the edge of the sink and I saw Steve had texted in the night, wondering how it had gone.

Magical - everything you imagine (smiley face) cannot wait to tell what BBC was like! LOVE you so much.

He texted back several hearts and a thumbs up; followed by a surprising message. Kathryn showed up midnight- enjoyed each other 3X! .

I smiled and let out a soft chuckle and sent back, Can’t resist that Steve heat!

I washed my hands, although I don’t know why, and returned to the room. The early hours of sun were creeping through the dingy window, illuminating three bodies. Blankets and sheets and pillows were tossed about partially covering the trio. Dayton lay at an angle, his sister splayed across his body on her stomach. My gorgeous son Nathan’s head rightly lay on his girlfriend’s gorgeous ass, using it as a pillow.

What an incredible sight. It reminded me of when the Duke and Duchess find the sleeping lovers in the woods at the end of A Midsummer Night’s Dream. “What nymphs are these?”

I was going to climb back in, but realized that since I had left, they had adjusted, and my spot by Dayton’s monster was occupied. I wrapped a hand around his ass cheek and squeezed. I hummed in his ear. He moaned gently and through sleepy eyes, saw his new lover staring back.

“Good morning gorgeous,” I whispered. “The sun has just come up and we should get…” I stopped talking as he had turned his body in order to kiss me softly and lovingly on my lips. I moaned gently, kissing him back with a deep lust that was unexplainable.

“We still have plenty of time before we need to get going, right?” he whispered.

“Hmm, you are bad. Yes, but I’d liked to get back sooner so my mother-in-law can head home at a decent hour.” I was caressing his ass, and he was kissing my stomach. I saw his cock begin to twitch: no surprise there. “Why don’t we take a shower and let the love birds sleep a little longer?”

I gently slipped off and held out my hand and he followed, carefully extricating himself from his sister. The busty, ebony goddess moaned and rolled depositing my son’s face on her thigh.

Once the water had warmed up, I stepped in, and he came in behind me. I leaned back on his hard body, and he wrapped his arms around. I sighed in contentment. One hand held my right breast and kneaded gently while the other caressed my left hip heading in. I grabbed it and squeezed.

“Take it easy, Sarge, Private Jen has been through it.”

He chuckled as he gently kissed my neck and my shoulder. “I have a feeling she can take some on another front.”

To illustrate he pushed his massive erection into my ass crack. Oh fuck, I would not be able to deny him. Sore or not, he was going to have me.

"Not my ass yet. Take my-"

He was inside my pussy, and I slumped in response. He easily pulled me back up against him, his mighty member acting as a hook to hold me. Blissful energy reinvigorated my core.

“Fuck meee!”

A few minutes into the fuck, the bathroom door opened and Bunny stumbled in heading for the toilet.

“Jesus, you two are loud.”

I giggled as Dayton shoved his cock in and out of me from behind. It hurt so good. “Sorry girl, a bro needs his - ohhh fuck- MILF!”

***

We left the motel and headed back to the dorms to retrieve their prepacked luggage. Dayton and I made out in the parking lot. I was stroking him, wanting to suck him off again, but we were too public.

We had decided to get going and stop on the road for some coffee and breakfast. There was a mile of two of silence, and I believe all four of us were ruminating over what had happened.

For me, it was both pleasant and concerning. I now had four lovers in my life when less than six months ago I only had one! Checking the rearview mirror, my right, and my ring finger I sighed. I would just have to make it work.

A diner allowed us to fill up on a few things including bacon...and lots of coffee. Heading to the car, Dayton sweetly asked if I wanted him to drive. I tossed him the key fob and said that would be great. Bunny then surprised me and asked if she could ride shotgun.

I laughed, “No road head! Too dangerous!"

Nathan laughed out loud. “How the hell do you know what road head is?”

“Ha! your generation didn’t invent it. They just gave it a different name.” I climbed into the backseat, and we sped off.

Bunny laughed, “If you behave, Nate, I am guessing you may get some head yourself… which is completely unfair.” The last came out with comic brattiness.

As I stroked my son's erection through his jeans I teased her, "You wanted shotgun!" I then proceeded to take Nathan out and engulf him as deeply as I could in one go. Bunny was shocked and turned to her brother. "That is not okay! Like, I'm hornier now!"

Dayton laughed, "Her car, her rules. Don't worry, there is a rest stop in twenty minutes." Aghast she sat back, arms folded under her great boobs, and we all had a laugh at her pout. Nathan was probably going to be slow to release this time as he was fucking Bunny doggy when we came out of the shower less than ninety minutes earlier. Then again, he was eighteen.

I decided to wait myself, and popped off noisily. As I tucked him back in, he let out an exasperated grunt.

"You sound just like your girlfriend. Kids nowadays, no patience."

"Bunny's right," he comically pouted, "Unfair!"

At precisely twenty minutes we were pulling off. The rest area was not very busy, considering the holiday. Dayton pulled behind some semis on the far end and we all unbuckled quickly. Bunny nearly leaped to take her brother in a hot hug and kiss.

Nathan had me in a similar hold and was roughly yanking off my jacket. I had a mom moment when I told him to wait as it was a fave and I didn't want anything to happen to it. I was soon topless with my son on my breast, again. That will never get old. He was undoing his pants, and I was pulling mine down over my hips. I left them at my ankles so as to redress quickly. In a flash, he was on top of me and in me, all of his majestic firmness filling my tender hole in one deep thrust. I lost my breath and then yelped as my voice returned.

I glanced up front and Dayton had his seat back and his sister was riding him hard and wild.

"Fuck me, bro! Fuck your sister's nasty used cunt! God! I love big cocks!"

In a disturbingly sweet gesture, she reached for Nathan’s hand and the two squeezed with love and affection. I was moved to speak but couldn't. My son's torpedo was heading through my stomach and up my throat like he had something to prove. I loved being reclaimed.

"Ummph! god! Nathan - OOF! so deep - Oh gawwwwd!" I was close to cumming and I think he was too. I would find out later this was his first car fuck and he was determined to make it memorable. He was pounding me and sucking a tit again and I had the back of his shirt balled up in my fists. "Yes, baby yes, fuck Mommy hard. Oh yesss!"

I heard the bouncing of seats and the suspension of the car and smiled wickedly!

It must be obvious to any observers what was happening.

Thankful for steamy windows, I remained unconcerned.

Bunny was getting her own boob sucked hard, and from what she was screaming, was cumming hard.

Nathan looked up and smiled as he fucked me. "Look at her - umph- fuck her brother's BBC, Mom. Isn't that - ugngh- the sexiest - ungh- Ohhh fuck!"

I recognized that tone and grabbed his ass and pulled him in hard and locked down. His expulsion had the usual force but a bit less volume due to it probably being his sixth or seventh in twelve hours. I was still lost in the ecstasy of feeling the warmth of it flowing into me. The two in the front followed suit and were soon shouting their own joyful rapture.

It all screeched to a halt when there was a tap on the driver's window.

"Oh! fuck no!" Bunny scrambled off of Dayton and quickly redressed. I held onto Nathan and whispered for him to stop moving. "We can't be seen down here. Let him handle it!" My heart was racing as Dayton sent up the seat, sat up, and hit the button for the window.

"Howdy." It was an older woman's voice, a trucker apparently. "You lovebirds were really goin' after it."

She paused as Bunny softly mumbled, "Oh god oh god oh god..."

"So...me 'n' the boys over there were takin' bets as to how fast you and sis might get off," Dayton told us later she was referring to two other male truckers who nodded and winked at Dayton. Bunny was in a fetal position now hiding her face. "Seems I won by thirty seconds. So, just wanted to say 'thanks' and have a good trip."

Dayton was nonplussed. "Um, thanks, and, uh, you too, I guess..."

"Next time, I suggest you get a room or use the family toilet; that door locks." She said the last as if it was spoken from experience.

I was relieved she was leaving, and that it wasn't me behind the wheel.

Dayton started closing the window when she added, "Oh, and Mom, just so you know, you and Junior were even louder. Have a good'n'."

Without waiting for us to reassemble, Dayton had the car in reverse, then forward, and was speeding away. We were all trying to redress quickly. As I hooked my bra, I could not hold it in any longer. My laughter exploded and I lost my breath from its intensity. Nathan and Bunny followed and soon the four of us were racing down the highway, cum sated, teary-eyed, and laughing our way home!
