Cora and Mark were my friends from the good old days, when we were all in our young 20s.

Those had been wild and salacious times, full of frenzied sex and crazy hookups. Everybody had slept with everybody else, sometimes three or four at a time.

I missed those days. I had held on to my taut feminine physique, and at 42, I was single and still a sexy physical specimen. But I didn’t have a social circle of oversexed college-age bucks and bunnies around me anymore. I still enjoyed the occasional relationship or one-night stand with someone my age, but it wasn’t like the sex circus of my youth, when I’d fuck five different people in a week.

Cora got me on my cell as I was coming out of the gym. My body hummed with energy, like it always did after a satisfying workout.

“Dana? Can I ask a favor? Mark’s nephew is supposed to be staying at our house while we’re away, but I can’t get hold of him. Would you mind stopping by there to make sure everything’s okay?”

She and Mark were on vacation. Mark had been a ravenous stud once upon a time, but now he was a doughy middle-aged guy. Cora was still a looker, but she seemed to regard our shared sexual past as a youthful lark, one best forgotten.

“Sure, Cora,” I said, thinking of days gone by when I’d licked and fingered this woman’s pussy, and when I’d sucked and ridden the cock of the man she’d eventually marry.

They were both still good friends, though, a fact for which I was grateful. I drove over to their place, happy to help them out.

I pulled into the empty long driveway. Cora and Mark had a nice house. It sure beat the cheap apartments we all used to live in when we were all just getting by working as wait staff and bartenders.

Sitting there in my car, images suddenly washed over me. I remembered a vivid three-way I’d once had with Cora and Mark, long before they took their wedding vows. Mark’s muscular body thrummed with strength. His cock throbbed in my hand as I worked his thick shaft. Cora was sucking on my tits, nibbling my stiff nips. I reached down to trace her dripping pussy lips with my fingertips.

Later, Mark had pounded Cora from behind, while her face was buried between my sweaty thighs. Her tongue had flashed like an electrified whip. Then I’d been cowgirling on Mark’s dick while Cora stood in front of us and jammed her pussy against my open mouth. I remembered how we’d sucked Mark to his climax, both of us taking his load across our faces, then lapping the sticky spunk off one another’s chins and lips.

A moan escaped me. I realized I had closed my eyes and was starting to rub the crotch of my gym pants, sending nostalgic tingles of pleasure over my flesh. I blinked my way back to the present. The old days were gone, I reminded myself.

I had a key to the house. I entered through the front door, finding the alarm deactivated. The place was quiet. I was about to call out, then realized I couldn’t remember Mark’s nephew’s name. I better announce myself anyway, I thought, but then I hesitated again, freezing this time.

A strange sound had come from upstairs. I had barely caught it. It seemed raw and somehow animal-like to me. Fear held me for a moment. I wondered if a cat or a raccoon had gotten in. I strained to listen.

It was a very familiar noise. I realized it was the same sound I’d made just a moment ago, as I’d indulged in sexual reminiscences in my car in the driveway. Did the nephew have a girl over?

I went up the stairs. The door of the guest bedroom at the end of the hall was wide open. The intermittent moans were coming from there. Cora had said there weren’t supposed to be any other visitors, so I figured I’d startle the hell out of Mark’s nephew and chase off whoever he was with as a favor to Cora.

But I froze once more as I reached the doorway. My jaw dropped, and a hot flush overtook my skin. I recalled then that Mark’s brother was a twin, and that the nephew was named Dalton.

Dalton was the spitting image of Mark in his studly heyday, all trim muscle and sinewy limbs. I got a good long look at him, as he was laid out on the guest bed, naked, eyes squeezed shut, pulling on his cock and groaning with pleasure.

I stood helplessly transfixed, drinking in that gorgeous sight. I liked how his balls bounced as he jerked himself and how his lean young body flexed against the mattress. He couldn’t have been older than 22.

I should have backed quietly away, but I didn’t. His moans turned into an outright cry, and he started raining pearly juice onto himself. As he pumped his last spurt, his eyes opened — then he saw me in the doorway.

“I’m a friend of Cora and Mark’s!” I announced in a panic.

Instead of covering himself, he smiled languidly at me and reached for a tissue to wipe the come off his chest and tight stomach. I was still gazing at him, my pussy aching.

“He slurped on my clit, drawing pleasure out of me that was almost painful.”

He patted the bed. “Come sit with me.” He didn’t act at all embarrassed.

In a daze, I obeyed. Dalton brushed my blonde hair off my forehead and said, “You’re hot. You wanna fuck?”

Some middle-aged reflex almost made me act affronted. But then I grabbed his bare shoulders and jammed my mouth on his, stabbing my tongue past his lips. If he thought he could shock me with blunt talk, he had another thing coming. He seemed the essence of my good old days, a sexually liberal young man, comfortable in his skin and eager to share his youthful body.

Dalton answered my kiss, tangling his tongue with mine. He drew me down next to him. I pressed against his naked form, caressing his smooth, firm flesh. His skin was drum-tight, his muscles nicely defined.

He pulled my shirt off, and I shimmied out of my gym pants. His hands roamed over my body. He squeezed my breasts, pausing to pluck at my excited pink nipples. He reached behind to cup my ass, and I did the same to him, savoring the taut handfuls. Even though he’d just come, his cock was starting to stir again.

With a smooth motion, he moved me onto my back. He kissed my throat, then sucked on my tits, going back and forth between them until he began licking his way farther down. By the time he was flicking his tongue playfully over my navel, I had my thighs spread and my pussy was desperate for his mouth.

He got between my legs. I hugged his shoulders with my thighs. His hot breath teased my pussy lips, then his tongue speared me. He drove it deep into me, and my hips bucked. His tongue worked in and out. Then he slurped on my pulsing clit, drawing an intensity of pleasure out of me that was almost painful as it rose and rose. I clawed the mattress on either side of me.

Dalton licked and delved. I clamped my legs around his strong shoulders as my climax heaved through me. My ass lifted off the bed as I jammed myself against his face. Bliss thundered through my veins.

When he sat up, I saw his cock was fully hard. He grinned. His face was wet with my juice. I said, “Get up here and put that cock in my mouth.”

He scrambled up my body, straddling my chest. I took hold of his vein-lined cock and put my lips around the swollen crown. I swirled my tongue over his cockhead. Then I put my hands on his hips and started pulling him forward.

He leaned over me, bracing his hands on the headboard. He slid his shaft into my mouth, and I swallowed everything he had, taking him all the way. I’d lost none of the proud cock-sucking skills of my youth. Dalton’s dick was deep in my throat, and his balls were against my chin.

I gave him a few encouraging purrs, and he set off fucking my mouth. It was beautiful, the long slow slide of him, his taut shape flexing above me. He grunted with pleasure. His every plunge filled my mouth, distending my lips. I sucked on him, caving in my cheeks around his sweet intruding staff.

He could have come like that if he’d wanted, and I would’ve swallowed his cream. But I was shivering with renewed need, and he must have sensed it. He withdrew his cock from my mouth and moved back down my body.

“Yes!” I cried. “Yeah! Fuck my pussy!”

Grinning, he slammed his cock deep into me. I was jolted with maniacal pleasure. My hips lifted. I wrapped my gym-toned legs around his waist. I pulled him as deep inside myself as was possible, feeling him at my tender depths, where the old joys had all come to new life. The years vanished. I had never regretted any of what I’d done. This was like revisiting those halcyon sexual times. This moment with Dalton was both casual and intimate. We were two frank beings, attracted to one another. It didn’t matter that we’d met moments ago. We were following our natural instincts.

It was just a bonus that he was 20 years younger than me.

Dalton stroked hard into me. My body heaved and rolled under his. The sound of our flesh smacking together was like a series of thunderclaps. I grinned up at his face as it twisted, approaching an orgasmic grimace. Suddenly, my own second climax raced past his, and I was shuddering through a crazed bliss, my whole body on fire.

When I abruptly disengaged, Dalton looked dismayed. I growled, “Fuck me from behind!”

I spun over onto my hands and knees, and he scrambled to slot himself back into my hot pussy. He hammered me mercilessly, nearly knocking me flat.

As he let out a feral cry, fresh rapture consumed me. In the same instant he yanked his cock out of my snatch, and sizzling jets of cream were splattering my ass and showering across my back.

Eventually, we lay side by side, recuperating until our next go-around.

At some point, I knew I’d have to call Cora and tell her everything was fine with their nephew, but I had more pressing matters to address.
