Hell yeah!

With all demonic knowledge now available to you, you quickly teleported from the room, appearing directly in the center of your Mistress' summoning center in her audience room. There, you saw gigantic throne, carved from single red crystal into various sex scenes with **** detail, and almost infinite imagination. It's only occupant - you mistress - used it's size perfectly, lying across it on her side presenting her perfect body to you.

"My mistress" - you bow slightly, but don't fall to your knees, or avert your eyes. As a Champion, and Consort to Lilith, you can allow yourself levels of intimacy of which no other of her vassals can.

"Ah, my Champion arrived" - she purred softly - "I saw what you did to the twins. Very impressive, indeed. Now, come to me. I want to examine your new body, and in the meantime explain the details of your mission on Earth. I'd love to take few days or weeks to fully test your body and your new skills, but time... Time is master of us all... And time for us to act is shorter than we suspected. Now, take your human form, and come here."

As you approached Lilith, while you slowly dissipated your demonic features to the state you were in, when you awoke in twins room, Lilith slowly changed her position to sit, then stood up. As you came into meter range with her, your lust took over again, and almost instantly you grabbed her head, and stared to kiss her soft lips hungrily. She responded with gusto, and immediately slithered her tongue to dance with yours, while your tits and cocks pressed against each other. After only few seconds, Lilith broke the kiss, then started to lick your body from the earlobes, slowly tracing down your chest, and cock. In the same time, her voice echoed in your head:

"As you know, I brought the plague onto your city, a plague, infused with tiny bit of my power. This virus feeds on corruption of people, and any sexual act performed by infected - the more perverted, the better, and more powerful virus becomes."

Lilith's tongue reached your breasts, and she started to lick your nipples, occasionally sucking them, and delivering little bites, for minute or two, before she returned to exploring your belly with her tongue.

"Unfortunately, due to the Angels intervention, I had too few "patients zero" to spread it all over the Earth. And now with city quarantined, and with Angels secretly helping humans to develop the cure, my plan is on verge of failure. And there is where you come in."

Lilith reaches with her tongue connecting lines of your belly. You almost lose your breath, expecting her perfect lips on your cock. To your surprise, she turns your over, and start to slither her inhumanly long tongue in your ass. Eager to what will come next, you fall on all fours, presenting your ass completely. Your mistress purrs with approval, and soon you feel her cock tip slowly circling around your asshole.

"You are demon born from human, an event unforeseen, and unheard before. You are almost equal to me in power and knowledge, yet, no Angel can sense you, or even recognize your true nature. "

Lilith's cock finally stopped teasing your asshole, and started to penetrate it. Slowly, Lilith drove head of her cock through our sphincter, waited for few seconds, the without any warning, drove her whole manhood into you. Instantly without any hesitance, she started brutally sodomizing you. You squealed with joy, squeezing your metamorphic body around her cock, as strong as you could, while waves of inhuman pleasure washed over you.

"Your mission is simple: I'll send your to the surface, where you'll find as many humans possessing mindset as close to your former self as you as you can. Turn them to our cause, turn them into shemale demons like you. Let them spread the tainted seed, and in the meantime with the strongest... find Angels... and kill them aaaaaaaaaaach!!!

You felt Lilith's body tensing, then her cock exploding in her ass, triggering your own orgasm. For more than minute, both of you basked in glow, then afterglow of orgasm, before untangling yourselves. You waste no time, and summon your clothes, then stand in the center of the circle.

"You won't fail me, my Champion. I know it." With these words, she gestured royally sending you back to the surface of the Earth. you found yourself...
