Her body, transforming

"Wakey, wakey", you said as the mother opened her fluttering blue eyes. She was stunned as she saw you face to face, with your cock deep within her loins still pumping your dark cum inside her. While she enjoyed her pleasant dream, you had taken the opportunity to open her legs and fuck her raw. It was only now, as you both climaxed, that she finally rose from her slumber.

The woman almost jumped backwards at your sight in shock, but you had her pinned down, grabbing her firmly by her waist. "Is-is this a dream?", she asked, flabbergasted. Yet she knew the answer to her question already.

"You tell me", you chuckled as you saw the effects of your dark cum infecting her body, spreading through her veins. "Does this feel like a dream?", you pulled your hips and then pushed your stiff cock inside her again, making a wet sound as it hit against the rivers of cum accumulated in her. Mary was unable to contain a yelp of pleasure, even after seeing how her skin was now tainted in black. "But then... then..."

"Then what you asked shall become reality. Get ready for your transformation... sister", you laughed out loud and pulled out of her to watch the show.

The middle-aged woman gasped, grasping her already decent breasts as they exploded outwards becoming a full and firm F-cup. Yet her hands were unable to contain their growth, nor the other changes in her body as all her excess fat vanished and her butt raised, leaving her with a perfectly sensual figure on it's own. But more was yet to come, as the age marks on her face and skin began to disappear, leaving her looking ten years younger. It was once she raised a hand to her face and the rest of her body that she stopped fighting it in her mind. Had she forgotten her dream? She had felt better than ever, and now the demoness in front of her was even giving her a body that most women would kill for.

"Nnngh... Yes...", Mary moaned, relaxing her muscles as she took joy and pride in her changes instead of fear and doubt. "Yes, yes...". Her hands reached down to her clit and began rubbing it vigorously, awaiting her orgasm... and something more.

"Yes what, my dear?", you asked, amused. This was your first corruption, and it was already turning out to be quite fun. You couldn't wait to see what the next ones would be like, with her daughters awaiting just next door.

"Yes... Change me! Make me a demon just like you!", she pleaded, with her horns already growing out of her temples and her eyes' sclera turning into pure black. You even saw how she moved her hips upwards to make room for her new tail. "Free me from my boring life!"

"Oh, that's already happening, my sweet Mary." Watching this single mother's full corruption was so sweet that it made your dick throbbing again in no time. And toying with her was almost as enjoyable. "But you need to be more specific. What do want, right now?"

Mary couldn't have imagined ever having these words coming out from her mouth, but now they seemed as natural as a simple hello. "I want a cock! I want a big, hard cock to fuck my daughters! I want to corrupt them into demon sluts like me!", she implored. A rush of energy crashed into her and she screamed out of joy as her clit pushed outwards, with both her hands enveloping it as it developed into a a massive 11 inch penis, as red as her whole skin now was. You didn't let her cum, however, even if she was fully ready for it. Her first time, after all, had to be memorable.

The sincubus mother understood your intentions right away. She only took one moment to stand straight into the bed and let her long, serpetine tongue lick the tip of her own penis and shuddered in pure lust. She needed to cum right away. And there was only one way her corruptor would let her do it.

The images of her two young daughters flashed in Mary Jones's mind. Her evil smile grew longer than her erect cock...
