And cum... and cum... and cum...

The two of your spend hours, with your bodies pinned to one another, grunting, gasping, and orgasming together. And every time you think you're done, another few loads are already racing down the pipe. You've been cumming for so long, that you've forgotten, remembered, and forgotten again, a time when you weren't cumming. But throughout all that, there is one thing you know you need to do. And that is to keep pumping your thick, fertile seed into her ravenous, life bearing, bottomless womb.

So it is no surprise, that it is a total surprise to you, when you realize that you've stopped cumming about ten minutes ago, and the sheer pressure of Selas' pussy walls clamping down around your cock is what was keeping it erect. Pulling out of her is almost as good as going in, but you are completely drained. Flopping onto the divan, you take long deep breaths while Selas curls up next to you. She looks down at her groin, and if you could move, you would see that not a drop of your cum has spilled out. "Do you think we did it?" she whispers, batting her eyelashes at you. You let out an exhausted chuckle and put your arm around her shoulders, telling her that you hope so, because there is no way you are capable of doing that again.

A faint, shimmering glow starts to envelop her. Her horns, wings and tail, grow and shrink as her body begins to mature. You barely react as the brick and nebula walls crumble to reveal the drab walls of your spare room. A window returns to view and you see that night has fallen, but you're not sure if it's the same day anymore.

Selas, back in her usual body, looks just as exhausted as you do. Snuggling up even closer, she gently kisses your cheek before dragging a wing over the two of you. Taking your hand and placing it on her stomach, she whispers into your ear, "Our first baby," before falling into a deep sleep.

But, despite how exhausted you are, you can't sleep. Those three words keep you up all night.

"Our first baby".

You look down at her peaceful face to her flat stomach. You have just filled her up with an ocean's worth of cum, and in her womb, will be your first child. Your half-demon child. Tucking your hand behind your head, you sigh loudly. This is your life now. A breeding stud for demonesses.

From your contract, you know that you're going have at least eleven kids, and that five of them will be allowed into the human world. You've damned the world. And as the sun's light peeks in through a window, you pray. Pray that whatever influence you have over your children, will be enough to give humanity a chance. You pray.
