As I entered my room to grab a change of clothes, the realization that we had the house all to ourselves for two days sank in. Riya and I exchanged a look – it was time to take our affair to new heights. With no parents around, anything seemed possible.

Riya sauntered into my bedroom, an impish grin spreading across her face as she eyed me up and down. "So many rooms, so little time," she teased. "Where do you want to start?"

I smirked back at her, already hard beneath my jeans. "Bed first – we'll work our way through the house."

Riya giggled wickedly before shedding her clothes and climbing onto my bed. She leaned back against the pillows, spreading her legs in invitation as I stripped off my shirt and unzipped my pants to free my throbbing erection.

"Fuck me hard," Riya commanded breathlessly. "Destroy your little sister's pussy."

I obliged without hesitation – plunging into her slick heat with savage intensity. Riya threw back her head, moaning loudly as we fucked in a frenzy of passion and lust. I gripped her hips tight, slamming my cock deep within her eager cunt.

"Fuck... this cunt belongs to big brother now," I grunted, pulling out only to plunge back inside relentlessly.

Riya's face twisted in pleasure-pain, her nails digging into my shoulders. "Yes! Fill me again – I want to be dripping with your cum all day!"

As we fucked, I marveled at how far we'd fallen. From casual flirting and stolen kisses, our affair had spiraled out of control, leaving no room for guilt or remorse. We were utterly addicted – craving each other's bodies like junkies seeking their next fix.

With her pussy still pulsing around my cock, I flipped Riya onto her stomach and spread her legs wide, admiring the sight of my cum-slicked dick disappearing into her greedy cunt once more.

"I want to fuck you in every room," I growled against her ear as I pumped my hips furiously. "The whole house will know you're mine now."

Riya whimpered loudly, her body trembling with each thrust. "Fuck... yes! Make me your slut all day long!"

As the weekend wore on, we worked our way through every room in the house – fucking on the living room sofa, against the kitchen counter, even during showers in the master bath. Each encounter was hotter and more reckless than the last.

After an exhausting round of sex in Mom's bed, I collapsed onto Dad's side of the mattress, panting heavily as Riya sprawled across me. We were both covered in sweat and cum – the remnants of our all-day marathon fucking spree.

"You're going to make me a single mom one day," Riya quipped, her voice husky from all the screaming we'd done over the weekend.

I chuckled darkly, tracing lazy circles on her back with my fingertips. "Fuck... I'm already addicted to your pussy."

As the sun dipped below the horizon outside our bedroom window, marking the end of our private orgy fest, Riya shifted against me once more and whispered something in my ear that chilled me to the bone:

"Let's get married one day – we'll tell everyone you're fucking your little sister because she's pregnant."
