I couldn't breathe. Rage and something far more dangerous surged through me as I watched my brother and my supposed mate writhing on the ground together. Ronan's hands were all over her naked body. Seraphina's back arched, her lips parted in pleasure. The sight hit me like a physical blow.
"What the actual fuck?" The words tore from my throat before I could stop them.
Seraphina's eyes flew open, panic replacing the desire that had darkened them seconds ago. She shoved against Ronan's chest, scrambling for her clothes.
My brother rolled onto his back, breathing hard, making no attempt to hide his arousal or his frustration at my interruption.
"It's not—we were just—" Seraphina stammered, clutching her tank top against her chest like a shield.
"Just what?" I demanded, my eyes raking over her naked form against my will. My body reacted instantly, and I hated myself for it. "Sparring? Is that what you call it?"
Ronan sat up with infuriating casualness. "You should knock."
