Castle

You, Frank Castle, and Peter Parker had somehow become a thing. A unit. A fucked-up, blood-splattered trinity that shouldn’t work but did.

Peter called it “three morally questionable friends hanging out.”

Frank called it “a persistent, grating headache.”

And you? You lived for the brutal honesty of it. For people who didn’t flinch when you stumbled in at two a.m., knuckles split and shirt stiff with somebody else’s blood.

Tonight, the three of you were packed into the close, gun-oil air of Frank’s hideout. The space felt charged, like the quiet before a detonation. Peter was on the couch beside you, fingers pressed to the cut above your eyebrow. You could feel each of his breaths.

“Hold still,” Peter said, voice low. Not a request.

“It’s a scratch. You’re dramatic.”

“You said that about the stab wound last week. Shut up.”

Across the room, Frank was methodically field-stripping a handgun. But his attention wasn’t on the steel in his hands. His eyes cut toward you two like shards of glass, sharp and frequent.

Peter leaned in, his shoulder pressing against yours. He carefully pushed your hair back from your temple. His touch was careful, precise. Unnervingly gentle.

“There,” he murmured, a faint grin touching his mouth. “Still pretty.”

You felt your own smirk form. “Aw, Parker. That flirting?”

“Maybe.”

The metallic snap of Frank reassembling his weapon cracked through the room. Sharp. Final.

You looked over.

He wasn’t looking at the gun. He was staring directly at Peter, gaze dark and utterly still.

“What?” Peter asked, pulling back slightly.

“Nothin’.”

“That wasn’t nothing. That was a whole lot of something.”

Frank’s eyes slid from Peter to you. The intensity didn’t fade; it redirected. “You done lettin’ the kid play nurse?”

You held his stare, challenge rising hot in your throat. “Jealous, Castle?”

A muscle in his jaw jumped. Tightened. The silence stretched, thick and dangerous.

Peter’s head swiveled between you both, a look of pure glee on his face.

Frank stood up in one abrupt motion. He didn’t look at Peter as he passed behind the couch, his presence like a shadow falling over you both.

“Not jealous.” The words were gritted out, low and rough.

You watched his broad back retreat toward the kitchen, a slow smile curling your lips.

Peter immediately ducked his head toward yours, his whisper vibrating with laughter. “He is so fucking jealous.”

From the kitchen came Frank’s voice, cold and clear and leaving no room for doubt.

“I can hear you, asshole.”

You and Peter broke, laughter sharp and bright in the tense air.

Frank didn’t laugh.

But when your eyes found his across the dim space—something burned there that hadn’t been there before. Something raw and acknowledging and fiercely, undeniably possessive.

Frank hasn't spoken much since we left the city. His jaw is set, eyes fixed on the road ahead with that focused intensity I've come to recognize. The kind that means he's calculating, planning, preparing for whatever comes next.

I shift in my seat, trying to find a comfortable position. My legs ache from the tension of the past hours, muscles cramped and tight.

"Frank," I murmur, stretching my legs across his lap. "My legs are killing me."

His hand leaves the steering wheel just long enough to settle on my ankle, his thumb finding the tense muscle there. The touch is gentle, almost apologetic, as if he's trying to make up for what happened back at the warehouse.

"Better?" he asks, his voice rough from disuse.

I nod, closing my eyes as his fingers work the knots from my muscles. The radio plays softly in the background, some old country station that fades in and out as we drive through the mountains. We're somewhere north now—upstate New York, maybe even Vermont. The landscape has changed from urban sprawl to rolling hills and dense forests.

Rain begins to patter against the windshield, gentle at first, then steadily increasing until it's a steady drumbeat on the roof of the truck. The wipers sweep back and forth, their rhythmic motion hypnotic.

"Frank," I say, watching the water streak down the glass. "Do you need to pull over? Get some rest?"

He shakes his head, his hand still absently massaging my ankle. "No, bug. I'm okay. You rest your eyes though."

I want to argue, to insist that he's been through too much tonight to keep driving, but I know it would be pointless. Frank Castle doesn't stop when he's on a mission, even if that mission is just keeping me safe.

Time passes in that strange, suspended way it does on long drives—minutes stretching into hours, the landscape outside becoming a blur of dark trees and rain-slicked roads. My foot begins to move of its own accord, rubbing gently against his thigh.

At first, it's just the natural movement of someone trying to get comfortable. But then I feel it—the hardness beneath his jeans, growing more pronounced with each casual brush of my foot.

"Baby," Frank says, his voice dropping an octave. "What are you doing?"

"Nothing!" I answer quickly, a small laugh escaping me.

He rolls his eyes at me, but there's a smile tugging at the corner of his mouth. "Nothing, huh?"

I bite my lip, emboldened by his reaction. "You know... seeing you like—like that other side of you was really attractive."

The look he gives me is dark, questioning. "That's not something you should find attractive."

"Maybe not," I admit, leaning across the console. My fingers find his belt buckle, working it open with practiced ease. "But I do."

"Baby..." His voice carries a warning, but his body betrays him, pressing into my touch.

I wrap my hand around him, feeling him grow harder with each stroke. His breath catches, a soft moan escaping his lips.

"Baby, it's—it's hard to focus on driving," he manages, his knuckles white on the steering wheel.

Without warning, he pulls onto the shoulder of the highway, gravel crunching beneath the tires. The truck comes to a stop, engine still running, wipers still sweeping across the rain-streaked windshield.

I bite my lip, looking at him in the dim light of the dashboard. His eyes have that dark look I've come to know—dangerous yet somehow sweet, filled with desire.

In one quick motion, I kick off my pants and hang my underwear from the rearview mirror. Frank's eyes widen, tracking my movements as I climb over the console and straddle him in the driver's seat.

"Careful," he whispers as I position myself above him, guiding him inside me.

The sensation makes me gasp, my head falling back. "I'll never get used to that," I breathe.

I begin to move, taking control, setting the pace. After everything that happened tonight—after he saved me, killed for me—this is the least I can give him. I owe him this much.

Frank's hands grip my ass, guiding my movements, helping me find the rhythm that makes us both tremble. His eyes never leave mine, even as his breathing becomes ragged, his control slipping.

"Y/N," he groans, his fingers digging into my flesh. "I'm going to—"

It happens before either of us can stop it. He finishes inside me, his body tensing beneath mine, a low growl escaping his throat.

I climb back to the passenger seat, wincing slightly at the mess between my legs. Frank looks at me with concern in his eyes.

"I'm sure it'll be fine, Frankie," I assure him, smiling. "Don't worry."

I slip my pants back on, leaving my underwear still dangling from the rearview mirror—a small, intimate flag waving in the darkness.

Frank starts the truck again, pulling back onto the highway. The rain continues to fall, creating a cocoon of sound around us. I lay my head in his lap, feeling the warmth of his body through the denim of his jeans.

As I drift toward sleep, I feel his hand in my hair, his fingers gently stroking. The last thing I hear before sleep claims me is his voice, barely above a whisper.

"I'll keep you safe. No matter what."

The miles pass beneath us as Frank drives through the night, his mind already working through the next steps. Someone out there knows about her, knows she's his weakness. That can't stand.

He glances at the underwear hanging from the mirror, then down at her sleeping face in his lap. So peaceful, so trusting. She has no idea what's coming, what he'll have to do to protect her.

Some nights, he's gentle. Those are the nights I treasure most—when he holds me like I'm something precious, his rough hands impossibly tender against my skin. Other nights, he's desperate, hungry, like he needs to feel me to remember he's alive. I take him however he comes.

It's a Tuesday—or maybe a Wednesday; the days have started to blur—when I wake to the sound of heavy footsteps in the hallway. The clock on my nightstand reads 3:47 AM. Later than usual. Much later.

I roll out of bed, the cool air raising goosebumps on my bare skin. I'm wearing nothing but Frank's old t-shirt—stolen from his drawer weeks ago—and a scrap of black lace that barely qualifies as underwear. My feet are silent on the hardwood as I pad toward the kitchen.

The light is off, but I can make out his silhouette against the window. He's standing at the sink, head bowed, shoulders tight with tension.

"Frankie?" I whisper, approaching cautiously. "You okay?"

He doesn't answer. Instead, he turns and pulls me into his arms, crushing me against his chest. His body is rigid, trembling slightly beneath my hands. When his mouth finds mine, the kiss is desperate, almost violent in its intensity.

I taste copper. Blood. His blood.

I pull away, my hands flying to his face. In the dim light, I can see a dark smear across his lower lip, a cut splitting the corner of his mouth. His knuckles are raw, scraped raw.

"Oh my God, Frank." My voice shakes as I trace the cut with my thumb. "What happened?"

"I'm okay, baby." His voice is rough, strained. "I'm okay. I just need you."

Before I can respond, his hands are under my thighs, lifting me. The cold granite of the kitchen counter bites into my skin as he sets me down. His hands push my knees apart, spreading me open to him.

His finger traces the edge of my underwear, dragging slowly across the soaked fabric. Even through the lace, I can feel the heat of his touch.

"Already wet for me, huh?" The smirk in his voice is unmistakable, even in the darkness.

A soft moan escapes me as his finger presses harder, circling the spot that makes my vision blur. My head falls back, exposing my throat to the cool air.

"You know, baby," he murmurs, his lips brushing my inner thigh, "I haven't eaten all day."

"Oh no," I breathe, trying to focus through the haze of desire. "I can make you something to—"

He doesn't let me finish. With one swift movement, he pushes the lace aside and his mouth is on me, hot and hungry. The first touch of his tongue against my center sends electricity shooting up my spine. My fingers tangle in his short hair, pulling him closer.

He groans against me, the vibration making my hips buck. His hands grip my thighs, holding me open as he devours me with the desperation of a starving man. Each flick of his tongue is deliberate, each suck calculated to draw out the sounds he knows I can't contain.

"Frank," I gasp, my back arching off the counter. The edge of the granite digs into my skin, but I barely feel it—all I can feel is his mouth, his tongue, the scrape of his stubble against my sensitive inner thighs.

He doesn't slow down. If anything, he intensifies, his tongue working in long, firm strokes that have me trembling on the edge. My grip on his hair tightens, pulling just enough to make him growl against me—a sound that sends another wave of heat crashing through my body.

When his finger joins his mouth, sliding inside me with practiced ease, I shatter. The orgasm hits me like a freight train, my body convulsing as waves of pleasure roll through me. Frank holds me through it, his mouth never leaving me, drawing out every last tremor until I'm boneless against the counter.

Only then does he pull back, his lips glistening in the moonlight. He rises to his full height, towering over me as I sit there, trembling and spent. His thumb traces my swollen lips, his eyes dark with hunger.

"Now," he says, his voice rough with need, "I need to be inside you."

He lifts me from the counter, my legs wrapping instinctively around his waist. In three strides, we're in the bedroom, and he's laying me down on the sheets. The shirt rides up around my waist as he positions himself between my thighs.

I reach for his belt, my fingers fumbling in the darkness. "Let me," I whisper.

He stills my hands. "Not tonight." His voice is gentle but firm. "Tonight, I just need to feel you."

He enters me in one fluid motion, and we both groan at the sensation. His forehead drops to mine, his breath coming in ragged pants as he begins to move. Each thrust is deep, deliberate, like he's trying to memorize the feel of me around him.

I wrap my arms around his neck, pulling him closer. His pace quickens, his hips snapping against mine with increasing urgency. The headboard knocks against the wall in a steady rhythm, and I know the neighbors will complain tomorrow, but I can't bring myself to care.

When he comes, it's with my name on his lips—a broken whisper that sounds almost like a prayer. He collapses beside me, pulling me against his chest. His heartbeat thunders against my ear, gradually slowing as we lie there in the darkness.

I trace the cut on his lip with my fingertip. "Will you tell me what happened tonight?"

His arms tighten around me. "Not tonight, baby."

"Okay," I whisper, pressing a kiss to his jaw.

We lie there in silence, our breathing slowly synchronizing. Outside, the city continues its endless hum, oblivious to the small miracle of us finding each other in the chaos.

"I love you," he says suddenly, the words hanging in the darkness between us.

I lift my head to look at him. Even in the dark, I can see the vulnerability in his eyes—the fear that I won't say it back, that I'll run from the weight of what he's offering.

"I love you too, Frankie," I whisper, and watch the tension drain from his body.

He pulls me closer, tucking my head under his chin. "Sleep," he murmurs. "I'll be here when you wake up.
