Knot of the Cuckold King by Reyna Royal

Length: 32,400 words

In the shadowed realms of shifter lore, Queen Bellamy Strauss reigns with a curse that demands savage submission under every full moon—a feral beast craving an alpha's knot to quell her madness. To maintain her iron grip, she weds the unassuming Duke Adrian Cortez, binding him as her consort and forcing him into nights of exquisite torment: chained in thorn-laced gardens, he must watch her captain, Magnus Raveneaux, claim her body with brutal intensity, his knot stretching her wide while she mocks Adrian's impotence.

Bellamy revels in the cruelty, making Adrian taste the salty evidence of her ecstasy, whispering degradations that leave him trembling and leaking, his scholarly mind fracturing under the weight of shame and forbidden arousal. But as the moons cycle, the humiliation ignites something primal in Adrian—a dormant alpha bloodline stirring with furious hunger. He learns from the shadows, studying every growl, every thrust, until the degradation becomes his forge.

When the reversal strikes, it's cataclysmic: Adrian seizes control, ripping Magnus from her mid-knot and claiming the queen himself in a raw, soul-binding mating that shatters the court. The once-mighty bull is collared, reduced to licking the remnants of his replacement's dominance. A dark exploration of consensual cuckoldry's psychological depths, where torment twists into triumphant reclamation, filled with primal breeding, knotting desires, and the erotic thrill of power eternally reversed.
