Only a matter of time

It started out small, subtle touches that I tried to brush off as nothing more than a typical mother-son dynamic. But deep down, I knew there was something deeper simmering between us - a forbidden desire that could only lead to ruin.

At 42, I still had a rockin' bod thanks to years of yoga and the gym. My tits were full and perky, barely any sag to speak of, and my ass was pert and round. My sandy blonde hair fell in loose waves to my shoulders and my baby blues were sparkling with life. I may have been pushing 40, but I didn't look a day over 30.

My son Liam was a fine specimen of young manhood at 17 - all lanky limbs and surging hormones. We shared the same blue eyes and full lips, along with his dad's dark hair. He had a shock of it that always flopped into his eyes, and a chin dimple that made me weak in the knees. Lately though, my reaction to him had been anything but maternal.

It began with innocent touches - his hand brushing against my ass while we were cooking in the kitchen, or "accidentally" bumping up against me in the hallway. At first, I told myself he was just being affectionate, an overgrown boy needing extra attention. But when I caught him sneaking peeks at my tits and watching me shower through the steamy glass, I couldn't deny the truth any longer.

My son wanted to fuck me. And God help me, but I was starting to want it too.

I tried to put the brakes on, to distance myself and stick to neutral topics when we talked. But Liam wouldn't let it go. He'd find reasons to "happen" upon me - hanging around my room while I changed, traipsing through the bathroom door without knocking while I was washing up. Each instance was more brazen than the last.

And I did nothing to stop it. If anything, I found myself playing along, letting my robe slip to reveal a sliver of tit while bending over, or "forgetting" my towel as I got out of the shower. What kind of twisted whore was I, lusting after my own flesh and blood?

Late one night, after a particularly hot and steamy shower, I thought I was alone until I heard a soft knock at my door. Before I could call out, Liam slipped inside, shutting the door behind him with a soft click. My heart nearly stopped at the hungry look in his eyes as he drank in the sight of me, naked and dripping in my towel.

"Liam, what are you doing?" I stammered, clutching the terrycloth to my chest. "You shouldn't be in here!"

He took a step closer, tongue darting out to lick his lips. "Why not? We both know this is what we've been building towards, Mom. Fuck, look at you - so hot and sexy, I can't control myself."

I opened my mouth to protest, but his hand shot out to wrap around my wrist. With a jerk, he pulled me flush against his body, slamming his mouth down on mine in a bruising kiss. My mind screamed that this was wrong, so wrong...but my body was betraying me. I melted into him, opening my mouth to allow his questing tongue inside.

Liam groaned into the kiss as he palmed my tits roughly, rolling and tugging at my hardened nipples until I was keening into his mouth. My hands fisted in his hair as I attacked his mouth just as savagely, all tongues and teeth and biting lips.

Without warning, he broke the kiss to shove me backwards until I hit the wall, my towel falling to the floor in a forgotten heap. His eyes were wild as he drank in the sight of my naked body, from my heaving tits down to my soaked pussy. "Fucking hell, you're perfect," he growled before latching onto one of my nipples like a starving man.

I cried out at the exquisite pain/pleasure of his teeth grazing my sensitive bud, arching into his hot mouth. He switched to the other one, giving it equal attention as his fingers played with its neglected twin. I was lost in a haze of lust, barely registering when he stepped back and quickly stripped off his clothes.

When I focused back on him, all thoughts of protest fled at the sight of his huge cock springing free of his boxers. It bobbed heavily before him, already shiny with pre-cum and pointing straight at me like an accusation. "Oh God, Liam," I moaned, eyeing it hungrily. "Is that for me? Oh fuck yes..."

He was on me again in an instant, lifting me by the thighs to wrap my legs around his waist as he thrust inside me with one brutal stroke. We both froze for a second, heads thrown back as we savored the feeling of finally joining.

Then he was fucking me, hard and fast and ruthless against the wall as he pounded into me with animalistic grunts. The pain was immediate and intense, tearing through me like a wildfire as he split me open on his huge cock. "Fucking bitch!" Liam snarled. "You're so fucking tight - so fucking good! Take it!"

Tears streamed down my face as he ravaged me, but I met him thrust for thrust, pulling him deeper into me with my legs locked around him. It hurt like a motherfucker, but it felt so good at the same time - this forbidden joining of mother and son, something taboo and wrong and oh so right.

As he fucked me senseless, all thoughts of right or wrong flew out of my head. The only thing that mattered was this searing pleasure-pain as Liam used my body for his own pleasure. His hands dug into my hips hard enough to bruise as he pistoned into me like a man possessed.

"Fucking take it whore!" he panted harshly, sweat dripping down his face. "Milk my fucking cock! You love this don't you - fucking your own son like a dirty slut! Admit it!"

"Yes!" I wailed back at him through gritted teeth. "I love it - I love fucking you! God yes, use me! Fuck me hard and make me scream!"

Liam growled deep in his chest at my words before capturing my mouth again in a brutal kiss. He swallowed my cries as he hammered into me, the wet slap of skin on skin echoing obscenely in the bathroom.

I could feel my climax building already, coiling tight in my core as Liam's cock battered my g-spot relentlessly. His balls were slapping up against my ass with each brutal thrust as he chased his own release. "Fuck bitch, I'm gonna cum!" Liam snarled in my ear. "Gonna fill your cunt with my fucking seed! Fucking TAKE IT!"

With one last powerful thrust, Liam buried himself balls deep inside me and came with a roar. His cock pulsed inside me as jet after jet of his hot cum painted my walls, flooding me with his potent release.

The feel of him coming undone inside me triggered my own orgasm with shocking intensity. I screamed into Liam's shoulder as I came apart in his arms, my pussy clamping down on his cock like a vice as I trembled through the aftershocks.

We collapsed together in a sweaty tangle of limbs, both gasping for breath as we came down from our high. Liam gathered me close, peppering kisses across my face and hair as he praised my body in between heavy pants.

"Fucking hell Mom," he breathed in awe. "You feel amazing - so tight and hot. I knew you'd be good but goddamn...you're perfect."

I blushed at his words, still reeling from what we'd just done - the depravity of fucking my own son like a back-alley whore. But even as a part of me cringed at our actions, another part of me thrilled at the taboo pleasure of it all.

As we cleaned up and got dressed in silence, I could see the question burning in Liam's eyes - would we do this again? Part of me wanted to cling to my last shreds of decency and put a stop to this madness before it went any further.

But deep down, I knew it was only a matter of time before we gave in again - because as wrong as it was, that feeling of being utterly claimed and used by my own son was something I craved with every fiber of my being.

And as Liam pulled me in for one last searing kiss before slipping out of the bathroom, I knew it was only a matter of time before we took this to the next level...and God help me, but I couldn't wait.
