He has to chose

Tracy began to transform, turning red and sprouting her wings, horns, and tail as Ray looked up in horror at the beast his girlfriend was becoming while his cock was still inside her. She looked down at him, licking her teeth as she gently caressed his face.

"Oh my God, Tracy, what..... what's happened to you?" He asked as he was sure now he would die if he was allowed to cum inside her.

"This is what I am now," she said with a growl slowing down the movement of her hips to tease him.

"No...... please, say it's not true!" He yelled out, heartbroken at the creature Tracy had become. "I love you, Tracy."

"I love you too, and that's why I want you to join me."

"What?" He asked confused.

"Join me, become a child of Ariestia, and we can be together, forever," she said as she bent down and looked deep into his eyes. "Or, you can die, in the loving embrace of the woman you love. There is no better way to die, my Love!"

"Die?" He asked even more confused. "I want you back!"

"I am yours if you can accept what I have become. If not, then I will fuck you, all night long, in every kinky way you have ever imagined, fulfill every sick and perverted fantasy you have ever had, and slowly suck the life out of you. You will be so fulfilled that when the end comes, you will embrace it with a smile on your face. Or, you can join me, be with me forever, and we can share pleasures you can't even imagine. I still want you, I still want to be with you, but the beast inside me wants to feed as well, so make your choice," she said as her pussy gently squeezed his cock making his whole body jerk.
