A soft rustling sound yanks me from the depths of dreamless sleep. My eyelids feel like they're weighed down with lead as I force them open, the world slowly coming into focus around me.

Dawn light filters through my bedroom curtains, casting everything in a pale blue glow. I blink, disoriented, trying to place the source of the noise that woke me. That's when I see her, Lilly, perched at the edge of my twin bed, her auburn hair pulled back in a perfect ponytail as she leans down to tie her running shoes.

My breath catches in my throat. The early morning light plays across her skin, highlighting the defined muscles of her abdomen where her sports bra leaves them exposed. The sight sends blood rushing south so fast I'm dizzy with it.

"Hey," I manage to croak out, my voice rough with sleep.

Lilly glances over her shoulder, a small smile playing at the corners of her lips when she catches me watching her. "Oh, hey. Good morning," she says softly, finishing the double knot on her shoe. "I'm just going for a quick run."

I try to nod, but it's hard to move with Rose's weight pinning down half my body. She's still fast asleep, her head nestled against my chest, one leg thrown possessively over mine. Her red hair, identical to her sister's but wild with bedhead, spills across my shoulder like a curtain.

The slight movement seems to disturb her anyway. Rose stirs against me, her face scrunching up adorably as she fights to stay asleep. Eventually, she loses the battle and pushes herself up on one elbow, eyes barely open, hair a tangled mess framing her face.

"You're going out?" she mumbles to her sister, her voice thick with sleep and confusion.

"Yeah," Lilly confirms, straightening up. "Just for thirty minutes or so. I'll be back before anyone else wakes up." She leans over to press a quick kiss on my lips before heading toward the door. “Bye, Seth.”

As soon as the door clicks shut, I let my eyes drift closed again. The bed is warm, and Rose's weight against me is comforting. Perfectly calling for me to go back to sleep.

My thoughts screech to a halt as I feel Rose shifting beside me. The blanket rustles as she moves, and then I feel her hands at the waistband of my sweatpants, tugging them down with surprising determination for someone who looked barely conscious moments ago.

"Rose?" I whisper, my eyes flying open.

She doesn't answer, just continues her mission with single-minded focus. My sweatpants slide down my thighs, and before I can fully process what's happening, Rose is straddling me. I feel the heat of her bare skin against mine, she's not wearing anything below her t-shirt, and then she's sinking down onto me in one fluid motion.

A moan escapes me as I'm enveloped in her loving heat. My hands automatically find her hips, steadying her as she settles fully onto me.

"Isn't it too early?" I gasp, even as my body betrays my words by hardening completely inside her.

Rose looks down at me through half-lidded eyes, her hair a magnificent disaster around her face. She rolls her hips, drawing another involuntary sound from deep in my chest.

"It's our first time alone, though," she murmurs, her voice still husky with sleep. She moves again, a lazy undulation that sends sparks shooting up my spine. "Just you and me."

She begins a slow, almost dreamlike rhythm. Her eyes are barely open, her movements languid like she's still half-asleep, but there's something incredibly erotic about the way we’re fucking. It’s unhurried and intimate.

"God, Rose," I whisper, my voice thick with emotion. "I can't believe I get to be with you like this."

As she rocks against me, she looks down at me through heavy-lidded eyes, a lazy smile spreading across her face.

"Yeah, baby," she whispers, her voice soft and intimate in the quiet dawn. "Whenever you want. I love you."

Her words flood my chest with warmth that spreads outward until I feel it in my fingertips. I've spent so many years watching her from a distance, fantasizing about moments like this, and now she's here, real and warm and mine.

"I love you too," I tell her, my hands digging deeper into her hips as I begin to push myself harder.

She lets out a soft, appreciative moan as I thrust upward, meeting her halfway. Her head falls back, exposing the elegant line of her throat, and I'm struck by how beautiful she is like this, unguarded, undone, completely present with me.

The rhythmic dance of our bodies reaches a perfect crescendo when the bedroom door suddenly swings open with a sharp click.

"Seth, are you awake? I just… Oh."

My mother stands in the doorway, her power suit wrinkled from what must have been an all-nighter at the firm. Dark circles shadow her eyes as she takes in the scene before her with clinical detachment.

Rose doesn't register the interruption immediately. Her messy auburn hair has fallen forward, shielding her face as she continues to ride me, her hips still rocking away. One, two, three more thrusts before the reality of my mother's presence penetrates her lust-fogged brain.

When it hits her, Rose freezes mid-motion, her entire body going rigid above me.

"Mom?" I choke out, hands instinctively moving to cover Rose's exposed thighs. "You need to knock!"

My mother just blinks slowly, like she's processing a mildly interesting legal brief rather than walking in on her son having sex. She doesn't even have the decency to look embarrassed.

"I see you're up," she says dryly, stifling a yawn with the back of her hand. "Both of you."

Rose makes a strangled sound, somewhere between a gasp and a whimper. She's completely frozen on top of me, not even breathing, her fingers digging painfully into my chest.

"Did you need something?" I ask, trying to sound normal while my girlfriend is literally impaled on my cock in front of my mother.

Mom rubs her temples, looking more exhausted than I've ever seen her. "Just wanted to let you know I'm home. Big case wrapped up." Her eyes drift to Rose. "You must be one of the twins Seth mentioned."

Rose makes a small squeaking noise but doesn't turn around. Her face remains hidden behind that wild curtain of hair, but I can feel her trembling.

"Mom, please," I hiss, mortification burning through every cell in my body. "Can we talk later?"

She sighs heavily, like I'm the one inconveniencing her. "Yeah. Just make sure to use protection."

With a soft click, Mom pulls the door shut behind her, leaving Rose and me frozen in our compromising position. For a moment, neither of us moves, the only sound in the room our shallow breathing.

Then, to my utter shock, Rose starts moving again.

"What are you doing?" I hoot, desperate to halt her movements. "We have to stop!"

Rose flips her messy hair back, revealing flushed cheeks and eyes dark with renewed hunger. Her lips curve into that dangerous smile I know so well.

"Why?" she whispers, grinding down harder. "She saw us and didn't even care. She practically gave us her blessing."

"That's not…" My protest dies in my throat as she lifts herself almost completely off me before sinking back down with agonizing slowness. My body betrays me, hardening impossibly further inside her.

I glance nervously at the door, but Rose grabs my chin, forcing me to look at her. "Eyes on me, Seth," she commands, her voice husky with need.

My mind races through the logic. Mom clearly doesn't care. And Rose, beautiful, wild Rose, is moving with growing urgency above me.

With a defeated groan, I let my head fall back against the pillow, surrendering to the inevitable. "Fine. But we have to be quiet."

Something snaps in Rose then, like she's been jolted awake by an electric current. The sleepy, dreamy quality of our earlier lovemaking vanishes, replaced by something feral and desperate.

Rose lunges forward, pinning my wrists above my head with surprising strength. Her fingers wrap around my forearms like steel bands, immobilizing me completely as she looms over me. The playful morning haze is gone from her eyes, replaced by something primal and possessive.

"Don't move," she growls, her voice dropping to a register I've never heard before.

I test her grip, but she only tightens her hold, her nails digging into my skin just enough to send shivers racing down my spine. The pressure of her fingers makes my heart hammer even faster.

Her hips rise and fall with desperate intensity, her body claiming mine with each powerful thrust. The bed frame creaks beneath us, protesting the force of her movements.

"Fuck," I groan, overwhelmed by the sensation of being completely at her mercy. My back arches involuntarily, trying to meet her halfway, but she uses her weight to pin me down more firmly.

"I said don't move," she hisses, her eyes flashing with something dangerous and thrilling.

A deep groan escapes me as she works herself on my length with relentless determination. There's something intoxicating about watching her take her pleasure like this, using my body exactly how she wants while I lie helpless beneath her. Her breasts bounce hypnotically under her thin t-shirt with each powerful thrust, her face a mask of concentrated pleasure.

The pressure builds inside me like a dam about to burst. Every nerve ending is on fire as Rose claims me completely, her wild movements growing more frantic with each passing second. I'm trapped beneath her, powerless to do anything but feel as she rides me toward oblivion.

"Oh god, Rose," I gasp, my voice breaking as I feel myself approaching the edge. "I'm close... I'm so close..."

Her eyes lock with mine, pupils blown wide with lust. "Me too," she pants, her rhythm faltering as her own climax approaches. "Together, Seth. Cum with me."

My entire body tenses as the first wave hits. I erupt inside her, hot pulses of pleasure shooting through me like lightning. Rose feels it happening and lets out a shriek that probably echoes through the entire house, her body convulsing around mine as she reaches her own peak.

"Seth! Yes! FUCK!" she cries, collapsing forward to capture my mouth in a desperate, messy kiss.

I moan against her lips as she continues to milk every last drop from me, her inner walls clenching and unclenching around my throbbing length. Our tongues tangle together as we ride out the aftershocks, swallowing each other's sounds of pleasure.

When she finally breaks the kiss, we're both panting like we've run a marathon. Rose releases my wrists at last, allowing me to wrap my arms around her trembling body. She collapses against my chest, her heart pounding against mine.

"Holy shit," I whisper, running my fingers through her tangled hair. "That was..."

"Incredible," she finishes, pressing lazy kisses along my collarbone. "I love fucking you when you're pinned down like that."

“I can tell.”
