It all becomes clear

Mary sat up, sitting on his legs as his cock was throbbing again. She began to touch her pussy, fingering herself as she teased him, letting him just lay there and watch for a moment as his cock twitched, waiting to be touched again.

"You make so fucking horny Tommy. You wanna fuck me, don't you?" She said as she moaned, touching her body.

"More than anything," he said watching her squirm.

"You want to feel my pussy, sucking your cock while I moan your name."

"Fuck..... I want it... I want all of it!" He said watching his cock twitch with excitement.

"This cabin will become a shrine to our new life together. That new life starts tonight. A life of pure, fucking, pleasure," she said as she got down on all fours and kissed him passionately as she lowered her pussy down on his waiting member.

"Oh, Mary....... FUCK!" He screamed, feeling his cock slide inside his stepmom with ease as his hands gripped her waist like he was holding on for his life.

Mary grabbed his shirt and pulled it off of him before leaning forward again. She kissed his lips and ran her hands along his chest before starting to slowly move her hips, milking his cock before she grabbed his hands and placed them on her ass.

"Touch me wherever you want Tommy. Nothing is off-limits. My body is yours to do what you want."

Tommy moved his hands up her back, feeling the softness and warmth of her skin. He moved them towards her breasts, gently touching them before Mary grabbed his hands and pressed them hard against her tits. Her nipples perked up against the palms of his hands as he squeezed them harder, making her tilt her head back and moan, which only aroused him further to watch.

"Your cock feels so fucking good Tommy. So much bigger than your father's. I've never been fucked like this before. I want to cum all over it, I want to soak it and make it mine!"

"Oh God!" Tommy was overwhelmed by everything that was going on.

"It's you and me Tommy. You can have me whenever you want. Any time, any hole, as many times as you want. My body is yours, and your cock is mine!"

"Mary...... I....... this is...... the best......" he tried to say as she bounced on his cock non-stop while it began to tighten around him, squeezing his member.

"There's no better pussy than mine, and It's all yours, Baby," she said as her eyes began to turn black.

"Mary..... what's happening to your eyes?" He asked feeling concerned.

"It's okay Baby, this is all part of the plan," she said with a smile that revealed sharpened fangs.

"Wait.... oh my God... what's happening to you?"

"Don't worry, everything is going to be okay," she said as horns began to sprout from her head and a tail began to curl around from the base of her spine. "Ornara, my Queen, I am taking his virginity," Mary said as the room began to have a dark aura about it, and a storm began to brew outside.

"Good Mary, very good. The process will begin soon, once he has cum," Ornara's voice said filling the room.

"What's happening..... oh God, what is this?"

"Do not worry," Ornara's voice said. "You will help us create a new world."

"A new world? But what about Mary? What about......."

"Mary will be your other half, your lover, your mate, and together we will begin a new era of this world!"

"What? But I......."

"Shhhh," Mary said pressing her finger to his lips. "Don't worry Baby, I'll be with you every step of the way," she said with a growl in her voice as her tail started to tickle his asshole.

"Shit...... what are.... this feels so...... fucking........... yes...... I want it.... whatever this is..... I want it, I want you..... I want all of it!"
