All night

Tommy slid his cock out, noticing that it had grown larger among the other changes happening to his body. He felt different, but not just physically. All of the worries he had before about Mafy being his stepmom, stress from school, none of it mattered anymore as he flipped Mary over on her back.

"Are you gonna fuck me again?" She said with the sexiest look in her eyes as Tommy crawled up towards her and kissed her lips.

"Like you said, all night," he said again as they wrapped their arms around each other.

There was no longer any stress or concern. There was no shame or shyness. There was no worrying about what people would think, nor did Tommy care what really happened to his dad as he had this exotic, beautiful demonic woman in bed with him, and these new powers that made him powerful enough to please her as much as he wanted.

"I want you, Mary, I want you so fucking bad," he said as they continued to taste one another. "I've always wanted you since you met my Dad. I've wanted you since I came back from college."

"Well, I'm all yours now," she said as she threw her legs up around his waist. "Now give me that big fucking cock of yours."

Tommy obliged and slammed his demonic cock back inside her, making her tilt her head back and moan, which only turned him on more as he began licking the sweat off her skin.

The wings were a little hard to manage, but neither of them cared as they fucked for hours, rolling all over the place. At one point, one of the legs of the bed frame snapped, and they both rolled on the floor. Tommy wrapped his wings around them both to protect her, but at no point did his cock leave her insides.

The cabin was remote, but people who lived on the other side of the lake could hear strange noises in the distance. It awoke many people who wondered what sort of animal could make that kind of noise while the wildlife all ran from the cabin, sensing a predator. Even the bears distanced themselves from the lake at the moment as Tommy and Mary continued to fuck each other.

"Oh God...... don't stop...... don't ever stop...... FUCKING ME!" Mary screeched as his cock burst inside her again, his cum sending waves of pleasure through her that she didn't know existed.

Eventually, Tommy collapsed on top of her, finally feeling exhaustion set in after hours of non-stop sex. Mary just held him in her arms, stroking his hair with his cock still inside her.

"I got you, Baby, I got you, and I'm never letting go," she whispered in his ear as these two creatures accepted their new life, and looked forward to their future together.
