Slow and steady

As you enter the toilet, you remember that the best succubi are the most willing. So to ensure that you aren't misreading her, you release some pheromones as you shift back to demon form. "W-what are you?" she asks, half aroused-half terrified, "I am an incubus, a pleasure demon. I am here to give you pleasure like you have never felt before." Before you can speak any more she throws herself at you, smothering you with kisses "Take me, make me a demon slut!" she screams as you lift her off her feet and start to rip off her clothes. She reaches down and feels your hard cock as you finish ripping off her thong "Take me!!!!!!" she pleads.

You move away from her and lay down, she quickly gets the message and starts to lower herself down onto your demon cock. As she bounces she starts to shake "Why can't I cum?" she asks "Oh you will" and just as you say that, you unleash your sperm into her willing body as her climax hits her. You lay there and watch as all the imperfections in her body remove themselves and she turns red. Her wings unfurl as her horns appear.
