Chapter 6: The Long Knot
Vance
I was still buried to the absolute hilt inside Logan when my knot began to swell.
The physical transition was fucking exquisite—a slow, burning ignition that started deep at the base of my pelvis. My thick, heavily veined cock was locked inside the tightest, hottest, most welcoming heat I’d ever encountered in my life, and now the biological mechanism of the mating process was taking over completely.
The wrist-thick bulb at the base of my shaft began to inflate, expanding outwards with a heavy, unstoppable force that stretched my own stepbrother twice as wide as he’d been during our initial coupling.
Logan let out a loud, piercing scream beneath me, the sound raw, jagged, and completely broken. His inner walls panicked, fluttering and convulsing violently around the ballooning mass of my knot as it grew thicker, heavier, and completely unyielding. It was an absolute seal, locking the two of us together in the most permanent, biologically extreme way possible.
I growled low against the back of his neck, my elongated fangs grazing the sensitive skin right above his scent gland, my hips twitching in short, instinctive thrusts as the knot reached its full, obscene size.
“Fuck… that’s it,” I rasped, my voice completely wrecked from the adrenaline and the thickness of the pheromones. “Take my knot, little brother. Feel how deep your alpha is stuck inside you. You’re not pulling away from me now.”
