Semen Demon Cumflation

A portal opens on your bed one night and a busty demon emerges. What is going on, you ask yourself as she sniffs the air, smelling your sperm. Demoness Sydney Screams is hungry for cum and ready to make a deal with you. Accepting her deal, the demoness slides herself down between your legs and starts sucking your cock (implied) and moaning around it. You're harder than you've ever been before, and when you shoot your first load straight down her throat, she starts moaning in pleasure. Before she can climb on top of you to slide your hardness into her wet pussy, her moaning grows louder as her hands slide to her belly. Something is happening, she's changing!
