Chapter 7: Climax

Her fingers were a relentless, slick circle on Seph's swollen clit, the pressure perfectly in time with Alistair's deep, pounding thrusts into her ravaged butthole. A shiver, electric and final, racked Seph's body from her toes to her scalp, her internal muscles clenching in a vicious, involuntary spasm around Alistair's invading length. Seph turned her head, a slow, agonized pivot of her neck, and looked at Demi—really looked, her dark-lined eyes wide and shockingly vulnerable, stripped of all sarcasm.
