Cute little virgin making a deal with a Demon to get out of her arranged marriage. Demon agrees but he doesn't want her soul, he wants her first born. She doesn't know when it'll happen, she isn't sure she'll ever get married. Demon just laughs and throws her to the ground, raping away her virginity with his long, inhuman cock. She screams at first, begging him to stop, this isn't what she wants but the deal is already struck, she's forced to follow through on it. He fucks her deep and hard, relishing her screams as he breeds her repeatedly, fucking her harder and deeper when she starts coming on his cock and begging for more.
Cute little bred slut becomes addicted to Demon cock, summoning them over and over to fuck her full of cum as the first Demon's baby grows in her belly.
Cute little slut for Demon cock ending up nothing more than a cock addicted breeding slut for a group of Demons who love fucking human sluts.
When the whore finally dies she ends up spending eternity strapped down and fucked by any Demon and Hellhound that wants to use her cunt. If a few of those fucking her moan "mommy" in her ear as she comes on their cocks well, this is what she wanted, even if she didn't know it.
