Mary wants a Handmaiden

As Tanya stripped, Mary took in all her delicious curves. "Bend over the bed, present that perfect ass to me."

Tanya didn't know what it was, but Mary's authoritative tone turned her on even more. She didn't hesitate to do as she asked., bending over the bed.

Mary moved over to her, then promptly gave Tanya's butt a strong swat to her right ass-cheek. She smiled broadly. The flesh made a pleasing jiggle motion, but it was still very firm.

"Harder!" Tanya said, her voice strained from pleasure.

Mary was certain her grin couldn't be wider by that point. "You like to be spanked, T?"

"Yes. Please. Harder."

"I'll do you one better than that." Mary moved to her knees and started licking Tanya's sex. She heard the other girl moan before Mary suddenly gave her another spank.

"Shit!" Tanya cried out. Before she could say anything, Mary's tongue was worming it's way inside her. Suddenly another spank, this time on the left cheek. "Fucking shit!"

Mary giggled into Tanya's sex. She buried her face even deeper into Tanya's ass, her nose sandwiched between the other girl's ample cheeks. Suddenly both hands came down, spanking both cheeks at the same time.

"Damn it, Mary! You're going to ruin me for other girls!"

Mary smirked, pulling away for a moment. "I think I'd like that." Two of her fingers start thrusting into Tanya's sex. "I can do a lot more for you, Tanya. I can give you pleasure beyond what any woman could."

"Really?" Tanya looked back at Mary. She didn't know how, but she knew the other girl wasn't lying.

"Yes. I'm going to show you something, Tanya." Then Mary starts to transform, slowly taking on her silver demonic-goddess form.

Tanya stared transfixed as Mary transformed into a model of demonic, feminine perfection before her eyes.

"I am a princess of lust demons, Tanya. Second only to my mother. I want you to by my side as my personal handmaiden. The only pussy you will service is mine, or my mother's should she desire it." Mary smiled. "However, you can have all the cock you want. Any male, or males, you desire will be yours to do with as you please. The only authority you'd need worry about is mine, and Queen Lydia herself." She stood closer to Tanya, hovering over the bed. "Join me, Tanya. Be my Handmaiden, and I promise for the rest of eternity I will show you pleasure beyond all human ability to give."

Tanya stared in awe at the silver-skinned demoness, unable to do anything but admire Mary's immaculate body. Perfect breasts, wide hips, the most kissable lips Tanya had ever seen, and the lips of her vulva, probably the most desirable sight Tanya had seen. If she had to limit herself to just one woman for the rest of eternity, could she really ask for a better choice?
