After My Mate Chose My Sister Over Me

The antiseptic smell of the infirmary couldn't mask his scent. That intoxicating blend of pine and winter frost that made my fingers tremble as I prepared the therapy room. Alpha Alec Harrison's aura filled the space before he even entered—dark, commanding, and laced with something feral that called to the emptiness inside me.

"Keira." His voice was rough when he finally appeared in the doorway, his broad shoulders blocking most of the light. "I need you."

Those three words sent heat spiraling through me. I kept my expression professional, though my heart hammered against my ribs. "Alpha Harrison, please lie down. We'll begin the aura therapy shortly."

He complied, his movements fluid and predatory even in his weakened state. The obsidian claw mark on his forearm—a battle wound from last week's territory dispute—had healed poorly. His wolf was fighting him from within, making him dangerous to everyone except me.

"Your wolf is restless tonight," I murmured, placing my hands on either side of his temples. "Let me help you calm him."

My fingers traced the tense lines of his face, feeling the slight tremor beneath his skin. His eyes—those storm-gray eyes that had haunted my dreams for months—fixed on mine with an intensity that stole my breath.

"Keira," he said again, but this time my name was a prayer on his lips.

I shouldn't have leaned closer. I shouldn't have let my lips brush against his jaw. But the pull between us was magnetic, inevitable. His hands tangled in my hair as he pulled me down to him, and suddenly we were drowning in each other.

Hours later, I lay beside him, my fingers tracing patterns on his chest. The silence felt heavy with possibility.

"Alec," I whispered into the darkness. "What are we doing?"

His body tensed beneath my touch. I felt him withdraw before he even spoke.

"This is therapy," he said flatly, his voice suddenly clinical. "Nothing more."

I sat up, pulling the sheet around me. "Therapy doesn't involve—"

"Don't." The word cut through the room like a whip. I flinched as he stood, his naked body silhouetted against the dim light. "We don't need to discuss this."

"But I thought—"

"I said don't." His Alpha tone slammed into me, forcing submission into my bones. I watched him dress with mechanical precision, his jaw clenched so tightly I could see the muscle ticking beneath his skin.
