Keith succombs

Moving from her position, Sandra practically threw herself at Keith, mashing her new huge knockers against his muscular chest while jamming her long, skilled tongue into his mouth.
Slightly surprised by the ferocity with which Sandra was kissing him, Keith quickly regained his composure and began kissing back, his hands coming down to fondle the succubus‘s bubble-butt .
The demoness wrapped her tail around Keith's still erect cock, pumping it with the prehensile length, then guided the fat head into her hot cunt. Raising herself above him, she sank down on his member, her pussy lips stretching obscenely around him.

Sandra snarled into Keith’s ear, licking at it with her forked tongue while she gyrated in his grasp. "Fuck me, baby. Fill this slut's body with your dick and cum inside my hot cunt. You’re gonna give me everything, your cock, your spunk and finally your soul”. Keith groaned then pulled her hips down hard while his pelvis thrust upwards. The transformed woman smiled widely at her betrothed, thrusting her massive tits against Keith’s chest, milking his dick with her articulate cunt.

Behind her, Michael grasped the base of Sandra’s tail firmly, exposing her puckered asshole.
She purred and winked at him, staring at his hard cock pointing at her ass. "Yessss... fuck me, fill all my holes. I love it. I LOVE BEING YOUR FUCKING SLUT!"

Michael, mouth curled into a wicked smile as grabbed his cock, before slowly pushing it in her, but not in her asshole.

“Not now, little whore. Right now I will sample your pussy, I’m sure you have room for more”.

The succubus was shocked to feel Michael’s cock being pushed up her pussy along with the cock already there. Double-stuffed, she was howling with a mix of pain and pleasure as the two large dicks were stretching her to beyond proportions she thought she could endure. A normal human would probably suffer from the pain but for the new demoness, it was pure bliss, her preternaturally gifted pussy stretching enough to fit both of them. Their combined girth causing her labia to be pushed wide apart as more and more of their members disappeared into her.
Soon enough, Sandra was being rocked between her lovers as they began to fuck her pussy in earnest, humping against her with enough **** to make her be tossed back and forth between, making her howling in delight, drool trailing from her lolling forked tongue.

Her pussy seemed to explode as her honey poured and sprinkled out of it, thick gobs of it raining onto Keith’s belly. She was flexing her vaginal muscles like crazy all throughout her almost continuous climax.

“And now the coup de grâce” said Michael as he grasped Sandra’s tail. His brutal hand squeezed at its cockhead, squirting jism onto the floor below. Then, he thrust the rod into Sandra’s empty ass. The demoness shrieked and snarled like a beast, whipping herself onto the demon. She grabbed at her titanic boobs, squeezing the perfect globes in her dark blue claws.

"Mmmm... I can feel your soul Keith. I want it, now." The satanic whore whispered, licking Keith’s ear with her long tongue. "It feels so good to get rid of it; like your whole body bursts into a never-ending orgasm. Forever. And all you could screw me forever; I’ll be your fucktoy."

“Ah, fuck, Take it you whore, take everything” Keith said through clenched teeth as his cock started to fire ropes after ropes of spunk in Sandra’s overstuffed pussy.

The rutting trio came at the same time. An endless flow of obscenities streamed from Sandra’s mouth while her belly was swelling with Keith and Michael’s spunk. Keith was cumming so hard his soul shook free. The demoness seized the opportunity, grasping at it with her hellish powers and consuming his energy, sending its remnants to Hell.

Keith convulsed, heat racing through his veins. The hollowness in him burned, spreading throughout his body like wildfire. Sandra licked her plump lips and pulled Keith into a ravenous kiss, his growing fangs cutting into her tongue as it wrapped around his own forked appendage. When Sandra finally pulled back, he noticed the increased length of his own tongue; he realized it must reach a good 8 inches in length.

"Welcome to Hell, stud," she smirked sultrily. He stared at her with slitted eyes, his flesh turning into a dark green hue as large ram's horns curled from the sides of his head. As she dislodged herself from her lovers, his large cock plopped free of the succubus' gaping cunt, it stood tall and hard, his cockhead had engorged to the size of an apple, dark cum still leaking from it.

Finally the two incubus stood up in front of the kneeling whore, swinging their cum-covered fucksticks around to her thirsty mouth. Sandra was busy lapping at their dripping balls with her long tongue while their tails where kneading her sweaty tits.

“Now, you could reproduce what you saw in the movie with your coworkers,” Michael said.

“Mmmhh yess, but right now I think I will enjoy these monstercocks a bit more,” Sandra hissed before engulfing Keith’s dick in her hungry maw.
