Page 145 of The Rust in Her Hair

Adrian steps into the space I've left, then he guides his cock and sinks in. The groan that tears out of him is wrecked, hours of tension pouring out on one long exhale.

Lyra arches up off the desk to take him, gasping, her heels hooking behind his back.

And I move in behind Adrian. "Eyes on our omega," I tell him as I pull off my tie and shirt. "You're going to keep fucking her through every second of what I'm about to do to you."

"Yes," Adrian moans as he goes still, waiting for me to enter him.

I toss my clothes away, then put one hand flat between his shoulder blades and press him down, folding him over her, until his chest meets her breasts and the three of us are stacked together.

Adrian goes quiet, holding his breath as I line myself up and push into him. I'm still coated in Lyra’s slick, letting me slide right into him. His hole is a greedy, clenching thing, sucking me in. A tight, hot ring of muscle that resists for a second before yielding, swallowing my cock inch by inch.

Once I’m seated, Adrian moans, long and helpless, his body shuddering. And Lyra, feeling him jerk forward into her, lets out a moan so deep I feel it in the wood of the desk.

Then I start to move.

And god, the power of it. Every thrust drives through Adrian and buries him deeper into our omega. I fuck him, and he fucks her, and I'm the engine of all of it, both of my mates moving to my rhythm, both of them coming apart because of me.

The wet, slapping sound of skin on skin fills the room—my hips pounding into Adrian's ass, his balls slapping against Lyra's soaked cunt. Their moans mix together, a desperate, beautiful chorus. Wet and sharp, over and over, as I pound into both of them, the force of my thrusts making them writhe.

Soon my cock begins to swell and I lean down over Adrian's back, and sink my teeth into the meat of his shoulder. He shudders violently, clenching around me.

"We have to hurry," I growl against his skin. I have no idea how much time has passed, but that fire can only burn so long. "Are you close, baby?"

‘Yes." He's panting, his hips snapping into Lyra on every one of my strokes. "I know, I'm close, I'm so close⁠—"

"Don't knot her." I drive in harder, and he grunts. "There's no time. You hear me? Don't you dare knot her."

"I won't." He's wrecked, barely words. "I won't, I won't. I⁠—"

Lyra comes first.

She goes off with a scream, her body seizing, and I feel her come through both of them, her release wringing a strangled sound out of Adrian. He follows her over on the next stroke, spilling into her, his back bowing under my hands, his shoulder still caught in my teeth.

And the feel of the two of them clenching and shaking and coming apart in front of me finally drags me under with them.

I bury myself as deep as I can, and press the base of my knot against Adrian's tight ring of muscle, but I don't push it in. There's no time to lock us together, and coming without that pressure is its own kind of agony.

My knot swells against him with nowhere to go, the pressure building sharp and unbearable, and I groan through my teeth as I let go, spilling into him. It should feel like release, but without the squeeze my orgasm aches, my whole body straining for something it can't have.

I reach down and wrap a fist around my own knot, gripping hard, giving my body the pressure it's screaming for. Relief cracks through the pain, and I wince, riding it out.

Then I feel Adrian shift beneath me. His arm works down between his body and Lyra's, and I know he’s doing the exact same thing.

"Fuck," Adrian snarls, then he lowers his head into Lyra’s neck.

Her arms come around the alpha, holding him to her, caressing his neck and shoulders.

For a moment nobody moves. The only sound is the three of us breathing, and the far-off chaos of the party, and the faint crackle of something still burning somewhere in this house.

I press my forehead to the back of Adrian's neck and breathe.

Get it together. It’s time to go.

Forcing myself to move, I ease out of Adrian slowly, then reach down to spread him open with my thumbs, taking one quick look at the mess I've made of him. My cum slides out of his used hole, and something possessive rolls through me at the sight. I want nothing more than to drop to my knees and lap it up, but instead I make myself back off and give him room.

Adrian pulls out of Lyra, then stumbles backward, giving me a clear view of our girl.

Her pussy is swollen and gaping, cum and slick smeared everywhere. A thick line of it is already leaking out of her and pooling on the dark wood of the desk. When she shifts to sit up, more of it gushes out, falling over the edge of the desk and trickling toward the floor in a slow drip.
