BackBirch’s Vow: Blood and Thorn

Chapter 20 - First True Night

BIRCH

The world outside the Blackthorn estate is silent.

No wind. No birds. No distant howl of wolves on the hunt. Just stillness—thick, unnatural, like the air itself is holding its breath. The moon hangs low, swollen and red above the forest, its light bleeding through the canopy like old blood. Torchlight flickers along the stone walls, casting long, shifting shadows that look like claws reaching for the sky. The scent of pine and iron lingers—Kaelen’s scent—woven through the damp earth and cold stone.

And I’m not afraid.

Not of the silence. Not of the night. Not even of the bite mark still warm on my neck, pulsing like a second heartbeat.

I’m afraid of what I want.

Kaelen stands in the doorway of his chambers, his back to me, his shoulders broad, his spine straight. He hasn’t lit the fire. The room is dark, lit only by the faint glow of the moon through the arched window. He’s stripped off his leather vest, his dagger resting on the table beside him. His boots are kicked aside. His fingers flex at his sides—once, twice—like he’s fighting the urge to turn.

And I know he is.

Because he feels it too.

The bond—no longer a hum, no longer a whisper—is a roar. A fire. A need so deep it scrapes my bones. It’s been building since the ritual chamber. Since I kissed his wrist and felt the mate-mark *fade*. Since I whispered, *“I won’t break us. Not ever.”* Since he looked at me like I was the only thing keeping him from drowning.

And now—

Now, there’s no war. No trap. No Council. No Lysara. No Virellion.

Just us.

And the truth.

“You don’t have to stay,” he says, voice low, rough. “You can go back to your chambers. Lock the door. I’ll keep the bond from tearing you apart.”

“And if I don’t want to be kept?” I ask, stepping forward. “If I want to *burn*?”

He turns.

Slow.

Deliberate.

His eyes are gold—burning, human, *alive*. His jaw is tight. His chest rises and falls in slow, controlled breaths. He looks like a man on the edge of a cliff, one foot already over the edge.

“You don’t know what you’re asking,” he says.

“I do,” I say. “I’m asking for *you*. Not the Alpha. Not the enforcer. Not the king’s dog. *You*. The man who held a blade to his own throat. The man who swallowed truth like poison. The man who loves me.”

His breath hitches.

“Say it,” I whisper. “Say you want me.”

He doesn’t move. Doesn’t speak.

Just watches me.

And then—

He steps forward.

Not fast. Not rough.

Slow. Deliberate. Like he’s savoring every second.

He stops inches from me. His heat sears through the thin fabric of my tunic. His scent—pine, iron, wolf—floods my senses. His hand comes up, slow, like he’s afraid I’ll vanish if he moves too fast. His thumb brushes my cheekbone. Warm. Calloused. *Alive*.

“I want you,” he says, voice raw. “Every damn second. Every breath. Every heartbeat. I want you so fucking much it *kills* me.”

My breath hitches.

“Then take me,” I say. “Not as your mate. Not because of the bond. But because you *choose* to.”

He stills.

Then—

He leans in.

Not to kiss me.

But to *claim* me.

His lips brush my pulse. His fangs graze my skin. I don’t flinch. Don’t pull away. Just arch into him, offering myself, daring him.

And he doesn’t bite.

Not yet.

He pulls back. Looks at me. Gold eyes burning.

“This isn’t just sex,” he says. “This is a vow. A surrender. A *choice*. And if we do this—” His voice breaks. “—there’s no going back.”

“I don’t want to go back,” I say. “I want to *move forward*. With you.”

He exhales. Slow. Shuddering.

And then—

He kisses me.

Not soft. Not slow.

Hard. Desperate. A claiming. A challenge.

His hands fist in my hair, pulling me closer. His tongue sweeps into my mouth, fierce, hungry. The magic *explodes*—bright, hot, *alive*—pouring through me, through *us*, a river of light and heat and need. My knees buckle. He catches me, one arm around my waist, holding me up, holding me *close*.

I break the kiss—panting, my lips swollen, my eyes wild. “I don’t want gentle,” I say. “I don’t want slow. I want *you*. All of you. Now.”

He growls—low, dangerous—and lifts me, carrying me to the bed. He lays me down, his body pressing into mine, his heat searing through the thin fabric of our clothes. His hand slides up my tunic, his palm warm against my skin, his fingers tracing the curve of my hip.

“Say stop,” he murmurs, his breath hot on my neck. “And I’ll stop.”

“I won’t,” I whisper. “I *can’t*.”

He stills.

Then—

He undoes the first button of my tunic.

Slow. Deliberate. Teasing.

Then the next. And the next. Until the fabric falls open, revealing my bare skin, the rise of my breasts, the faint scar across my ribs from the Blood Trial. His breath hitches. His eyes darken.

“You’re so fucking beautiful,” he whispers. “Even broken. Even scarred. Even hating me.”

“I don’t hate you,” I breathe. “I *need* you.”

He leans down.

Not to kiss my lips.

But to kiss the scar.

Soft. Reverent. A promise.

Then he moves lower—across my stomach, down to the waistband of my trousers. His fingers hook into the fabric, slowly pulling it down, revealing the dark triangle of curls, the soft skin of my thighs. My breath hitches. My hips arch.

“You’re killing me,” he growls.

“Then do it,” I whisper. “Take me. Claim me. Make me yours.”

He hesitates.

And then—

He spreads my thighs.

Not rough. Not forceful. Gently. Carefully. Like I’m something precious. Something *his*.

And then—

He leans down.

And *tastes* me.

Not a kiss. Not a tease.

A feast.

His tongue sweeps through my folds, slow, deliberate, savoring every inch. I gasp, my back arching, my fingers clawing at the furs beneath me. He groans—low, dangerous—his hands gripping my hips, holding me still, holding me *open*.

“Kaelen—” I gasp.

He doesn’t answer.

Just keeps going—faster now, harder, his tongue circling my clit, his fingers teasing the entrance. My breath comes in short, sharp bursts. My body tenses. My magic flares—bright, hot, *alive*—pouring through me, through *us*, a river of light and heat and need.

And then—

I come.

Hard. Desperate. A scream trapped in my throat, a wave of pleasure so intense it feels like I’m breaking apart. My body convulses. My fingers dig into the furs. My magic *explodes*—a burst of light that floods the room, pulsing with the rhythm of my heartbeat.

He doesn’t stop.

Just keeps going—gentle now, coaxing, until the waves subside, until I’m trembling, breathless, *ruined*.

And then—

He climbs onto the bed.

Straddles me.

His cock—hard, thick, *alive*—presses against my thigh. I reach for him, my fingers wrapping around the shaft, stroking slowly, feeling the heat, the pulse, the *need*.

He growls. His hips buck.

“You’re going to kill me,” he says, voice rough.

“Then let me,” I whisper. “Make me yours.”

He looks at me. Gold eyes burning. “Are you sure?”

“I’ve never been more sure of anything in my life,” I say. “Take me. *Now*.”

He doesn’t answer.

Just positions himself at my entrance.

And pushes in.

Slow. Deep. *Full*.

I gasp. My body stretches. My magic flares. The bond *screams*—not in pain, not in fear, but in *triumph*. In *ownership*.

He stills.

“Birch,” he breathes. “Look at me.”

I do.

His eyes are gold. Burning. Human.

“You’re mine,” he says, voice rough. “Even if you don’t remember. Even if you don’t want to. You’re *mine*.”

“And you’re mine,” I whisper. “Not because of the bond. Not because of fate. But because I *choose* you.”

He doesn’t move.

Just holds me. Filled. Connected. *Whole*.

And then—

He starts to move.

Slow. Deep. A rhythm that’s not just pleasure, but *challenge*. A claiming. A promise.

I meet him—hips rising, fingers digging into his shoulders, breath coming in gasps. My magic flares—bright, hot, *alive*—pouring through me, through *us*, a river of light and heat and need. The bond *explodes*—not pain. Not fire. *Pleasure*. White-hot. All-consuming.

He groans. His hands tighten. His pace quickens. His fangs graze my neck. I arch into him, offering myself, daring him.

And he bites.

Not deep. Not to mark.

But to *claim*.

A sharp, sweet pain that sends another wave of pleasure crashing through me. I scream—his name, his title, a word I don’t know. My body convulses. My magic *explodes*—a burst of light that floods the room, pulsing with the rhythm of my heartbeat.

And then—

He comes.

Hard. Desperate. A roar trapped in his chest, a pulse of heat that floods me, fills me, *brands* me. His body tenses. His fangs sink deeper. My magic flares—bright, hot, *alive*—pouring through me, through *us*, a river of light and heat and need.

And then—

He collapses.

On top of me. Into me. *Around* me.

His breath is ragged. His heart thunders against my chest. His cock still pulses inside me.

And I know—

This isn’t just sex.

This isn’t just desire.

This is a vow.

A surrender.

A beginning.

He rolls to the side, pulling me with him, his body still pressed into mine, his arm a heavy weight across my waist. His breath is warm on my neck. His heartbeat steady against my back. The bond hums—low, insistent, *alive*.

I press my fingers to the bite mark on my neck.

Still warm. Still *his*.

“You didn’t have to bite me,” I say, voice soft.

“I didn’t,” he says. “I *needed* to.”

“And if I’d said stop?”

“I’d have stopped,” he says. “Even if it killed me.”

My chest tightens.

“And if I’d told you to leave?”

“I’d have stayed,” he says. “Even if you hated me.”

“I don’t hate you,” I whisper.

“Then why do you fight it?”

“Because I’m afraid,” I say. “Of needing you. Of wanting you. Of *loving* you.”

He stills.

Then—

He turns me.

Not rough. Not forceful. Gently. Carefully. Until I’m facing him, my legs tangled with his, my hands braced on his chest. His eyes search mine—gold, burning, *human*.

“Then stop fighting,” he says, voice rough. “Let me in. Let me love you. Let me *keep* you.”

My breath hitches.

And then—

I kiss him.

Not hard. Not desperate.

Soft. Slow. A surrender. A promise.

His lips move over mine, gentle, coaxing. His hands slide up my back, under my tunic, his palms warm against my skin. My magic flares—bright, hot, *alive*—and for the first time, I don’t push it down. I let it rise. Let it meet his. Let it *merge*.

The bond *explodes*.

Not pain.

Not fire.

Pleasure.

White-hot. All-consuming. It pours through me, through *us*, a river of light and heat and need. I gasp into his mouth. My fingers dig into his shoulders. My hips grind against his, seeking friction, seeking *more*.

He groans. His hands tighten. His cock presses against me—hard, thick, *alive*—and I arch into him, desperate.

“Birch,” he breathes. “We can’t—”

“I don’t care,” I whisper. “I don’t care if we die. I don’t care if the world burns. I just want *you*.”

He looks at me. Eyes wide. Chest heaving.

And then—

He flips me.

Not rough. Not forceful. Gently. Carefully. Until I’m beneath him, my legs straddling his hips, my hands braced on the furs. His eyes search mine—gold, burning, *human*.

“Say it again,” he says. “Say you want me.”

“I want you,” I say, voice rough. “Every damn second. Every breath. Every heartbeat. I want you so fucking much it *kills* me.”

He smirks. Low. Dangerous.

And then—

He pushes in.

Slow. Deep. *Full*.

And I know—

This isn’t just survival.

This isn’t just desire.

This is the beginning.

Of everything.
