Travis's fate

"Amy....... I don't.......... I don't feel......... something's wrong," he pleaded as the pleasure he was feeling was so intense he didn't want it to end but he knew something wasn't right as the demonic-looking version of his girlfriend continued to ride his cock.

"I want more!" She growled at him as she milked his cock.

A tail suddenly sprouted from the base of her spine curling around. Her hands had turned red and her fingernails had grown longer and turned black as she leaned down and licked his face.

"Amy...... what's happening to you....... I feel......" he began to say as he felt that strange warm sensation inside him begin to glow down towards his cock and he was suddenly afraid to cum. "No....... please....... I can't........ I'm gonna......... I'M GONNA!"

Travis bucked his hips feeling his very essence being pulled down towards his genitals as Amy suddenly stopped for a moment, hearing a voice in her mind that said: "he would make an excellent **** my child."

Amy stopped leaving him right on the edge as a smile came across her face. "Yes Felysha," she said as her tail curled in front of her and she carved a strange symbol into Travis's chest that began to glow and burn as he screamed in pain. "Now, you're mine!"

"I...... yes master Amy," he said as his eyes turned yellow for a moment and he was suddenly under her control laying there.

"No be a good boy and cum for your master," she said gently moving her hips. "Cum for me. I command you.......... CUM!"

"Oh GOD!" He screamed as he began to cum even harder than he had before feeling that warm sensation flow out of him.

The pleasure was **** and he began to feel his muscle mass start to shrink. The athletic man he was before was gone as he was becoming weak and small but it didn't matter anymore. Travis was now nothing more than a mindless **** to the succubus Amy had been transformed into by Felysha who was fucking her brother in the other room.
