Demonic mating

Becky knew she had to take action. She kissed her lover once more, taking his lips and throwing her hips towards him. Her legs wrapped around his dick, forcing the giant staff inside her pussy. It was amazing, unbelievable. She could tell her inner parts had becoming far more sensitive, ready to host her master's meat. She moved her hips furiously as the penetration continued and her tongue found its way inside the demons throat. Her breasts were strongly pressed against his hard chest, squeezed by his muscles. She then felt the demon's tail twisting around her legs, ready to reach her ass and simultaneously fuck her from behind.

Her body was stuck in a continuous series of spasms and convulsions, rocking every muscle from her legs to her head. The transformation was finally entering its final stage, as Becky prepared to become something more than human. The tentacle thrusted inside her was, while the demon's cock continued to push inside her pussy. God, it felt good. Her breasts were still growing, pushed by an unnatural **** coming from inside her body.

-Master... I cannot resist anymore!-

The demon shouted in an inhumane howl. His mouth wide opened as a scream of pleasure came from the depths of his lungs and maybe even the depths of hell itself. Becky knew something unbelievable was going to happen, but she was no longer scared. Her body was ready, and her soul too could no longer wait for the final corruption, the transformation which would turn her into the demon's bride with no coming back.

They came together, the demon releasing his load of sperm inside her at the same time Becky begun to scream. She felt the hot cum fill her, reaching her womb and still trying to push even further. Her body exploded with pleasure, as her nipples burst open, revealing a mass of thin moving tentacles which covered her tits forming some sort of a living bra. Becky cried, hot tears falling along her cheeks as her last vestiges of humanity died with a last scream of pleasure.

-Aaaah!-

As she screamed her voice changed, becoming somewhat louder and a bit lower; under the tentacle mess, her boobs continued to swell, and her nipples begun to drip black milk which soon begun to come through her living bra and fall on her body. The tentacles squeezed her breasts more and more, continuosly moving and revealing glimpses of skin under them. It was amazing, Becky had never felt more alive. On some other parts of her body hard scales had begun to form, covering her elbows and knees with a black layer of hardened skin. Her feets too had grown scales and claws, with her fingers instead becoming slender and thin.

-Master...-

-Don't call me master, as I have made you my bride. I am Shanazhot. Your lover. And you are now Lilith, mother of a thousand demons. -

Becky smiled. Yes, what was that old, dull, human name? She had been given a tremendous gift, the power of hell itself. She had slept her whole life, and now her lover, her master, the future father of her children had awaken her from her slumber. He was Shazanot, and she was Lilith. Two halves of the same thing. The king and queen of hell.

-My love, thanks. But I want more, I want you again inside me...-

The demon smiled, caressing Becky with his hand. Becky loved that touch, the same touch which had managed to reforge her old self into a new identity, an old rusty piece of iron thrown into the forge of hell only to emerge once more as a mighty sword.

-I know what you want. I can smell it. Your body clearly tells me. -

Becky kissed her lover once more, feeling safe in the demon's strong embrace.

-But you have a mission. A duty. I made you anew for a reason. Rise Lilith, rise Queen of Hell!-
