MARKED BY MY STEPBROTHER

Chapter Sixteen

Sophie's POV

The golden chains around my wrists, ankles, and waist behaved like they were living things, slowly dragging us deeper into the heart of the mountain. The stone floor beneath us sank inch by inch, carrying us downward into darkness lit only by those glowing runes.

I clutched our newborn son tightly to my chest with one arm, his tiny body warm and glowing faintly gold against my skin. He let out a soft, hungry cry, and nuzzled himself toward my breast.

“Damon..” My voice cracked. “What’s happening?”

He groaned, forcing himself upright despite the deep wounds across his back. His silver eyes were filled with something I couldn't quite place as he wrapped his arms around us. His naked body was pressed against mine, still sticky with sweat, blood, and the mess from our last mating.

“The mountain, it probably wants the child,” he said. “It wants us. The True Alpha has been born. And we are the sacrifice.”

Another contraction, a bit milder this time, rippled through me as my body worked to deliver the afterbirth. I whimpered, and Damon immediately shifted closer, his thick c**k, still a bit hard, pressed against my thigh.

“You need me again,” he said, completely sure that was the case. “To heal, to feed the bond. So let me take care of you.”

I should have been exhausted. I had just given birth in the middle of a collapsing mountain while being hunted by monsters. But the heat was still alive inside of me, and it was demanding more. My p***y throbbed, wanting to be filled again.

If someone had told me that I would be f****d senseless in such way during my lifetime, I would have laughed and called that person an asshole. That such a thing was never going to be possible. But it was happening already, and guess what? I wanted it too. It wasn't as if I was feeling bad about it. I felt like I deserved every single mating experience that I was getting.

“Yes,” I whispered desperately.

Damon carefully helped me lean back against a smooth rock as the platform continued descending. He took our son gently and placed him on a soft bed of glowing moss nearby, where the baby went quiet, and watched us with those tiny silver eyes.

Then Damon was on me.

He spread my legs wide, staring down at my freshly f****d, c*m-dripping p***y with heightened hunger. “Look at you, still leaking my seed even after giving birth to our pup. So f*****g perfect.”

He thrust into me in one smooth, deep stroke. I moaned loudly, the sensation intense after everything my body had been through. He f****d me slowly at first, deep and with purpose, grinding his hips so his knot rubbed against the sensitive part of my sensitive p***y walls.

“Damon..” I gasped, my fingernails digging into his shoulders. “Harder. I need your knot.”

He gave it to me. His pace increased, hips snapping powerfully as he drove into my c*m-soaked heat. The golden chains tightened around us, feeding energy back and forth between our bodies. Every thrust made the runes on the walls glow brighter.

“That’s my good girl,” he groaned, biting down on my neck, reopening his claiming mark. “Taking your stepbrother’s c**k so deep right after birthing his son. Such a perfect little breeding Luna.”

I came hard, clenching around him as fresh slick gushed out. Damon growled and forced his swelling knot inside of me, locking us together once more. He came so hard that he roared his pleasure, flooding my womb with another heavy load of c*m.

We stayed knotted, panting, as the platform sank deeper. Our son cooed softly nearby, glowing stronger with every pulse of our mating bond.

But the voice returned, louder now, vibrating through the stone itself.

“The cycle is complete. The True Alpha is born. The Luna and her mate shall remain in the heart, bound for eternity. Their power will feed the mountain.”

Golden chains tightened the more, wrapping around Damon’s neck and my torso. I felt my strength being slowly drained, pulled into the mountain.

“No!” Damon said, and began fighting against the chains even while still knotted deep inside me. “She’s not your prisoner!”

I reached out with my mind, pushing back against the entity. “We won’t be slaves. We choose each other.”

The mountain rumbled in response. The chains loosened slightly, but new visions flooded my mind, flashes of the past.

I saw Seraphina, my true mother, being betrayed by Victor’s father. I saw my own mother sacrificing herself to hide me. I saw centuries of Lunas being used as breeding tools and power sources for this mountain.

And then, a new vision.

This one offered a way out.

But it required a final, permanent claiming.

“Damon,” I gasped as another wave of heat hit me. “There’s a ritual. A true bonding. If we complete it, we might break free. But it means that we can never be separated again. Our souls will be tied forever.”

“Then do it.”

He started thrusting again with his knot still locked, short, powerful strokes that made me see stars. The chains reacted, getting hotter. Our son’s glow brightened in response.

I felt the mating bond deepen, twisting into something eternal. Pleasure came fast. I came again, screaming, and Damon followed, pumping me so full I could feel my belly swelling slightly once more.

The mountain shook and the golden chains shattered.

For one blissful second, I thought we were free.

Then the floor beneath us opened completely.

We fell.

Down, down into a vast underground cavern filled with crystals and a massive, beating heart of pure golden energy at the center, this was the true heart of the mountain.

Damon held me and our baby tightly as we continued to fall.

Just before we hit the heart, I saw something terrifying emerge from it, a huge shadowy wolf figure with eyes like stars.

It opened its jaws wide and swallowed us whole.
