He couldn't say no

Esau tried to open his mouth to speak, but couldn't. He couldn't say no. It was as if her mere presence defeated his will. He felt her high heel press harder against his head, and he knew what he had to say.

"I want to be by your side! Please, I need to! I beg you!" He didn't know what came over him as he begged desperately and pathetically. Naamah shook her head oh so slightly in disappointment. Belial moaned orgasmically as her master gave up.

"Good. You please me Esau. You were always such a subservient person," King Excelcia took her heel off his head, and sat back down on her throne, her legs spread wide, showing off her royal demonic cunt for all to see, "now come here and accept your gift."

He was compelled towards her, his arms and legs not moving on his volition. He fell to his knees in front of her, looking up at his mothers face. Her gargantuan breasts mostly blocked his view, but she was grinning.

"Lick, my ****, show your King what you can do."

He lowered his face to her snatch, kissing it just on the cusp. He kissed again with a note of sucking on the end. The thing smelled divine, so bitter-sweet, so rich and heady like expensive red wine. He pressed both of his thumbs on both sides, spreading the labias apart. It was a mix of human pink and black corruption. He gave her insides a lick. This was the last moment he held back. A moment later he was licking and sucking and kissing like a mad man, plunging his tongue deep inside, twisting it and lapping up her dripping sludgy femcum. Oily blackness dripped down his chin, her extremely potent secretions changing him immediately into her vision. He groaned as growths pushed against the back of his shirt, tearing through it and folding out into a pair of draconic wings. A thick tail sprouted out of the base of his spine, ripping his trousers off of him as it grew. Talons sprouted from both his fingernails and toenails, sharp enough to tear through flesh. His ass grew just a tad cushier, and he could feel his anus begin to self lubricate. His cock expanded visibly by the second, becoming longer and thicker, lined with bumps and spikes for brutal texture. His mouth started to fill with fangs, and his eyes rolled back, returning as pitch black. Lastly, a pair of coal black horns sprouted from his forehead, bursting through his skin. They grew in curves until they were longer than a forearm, ending with sharp nubs on the ends. Esau was a powerful demon now, just like his mother. His pleasuring became better as a result of his transformation, succeeding in even making the powerful King moan. It was only once, and after that she showed no sign of enjoying herself other than a smirk on her face. She pressed her taloned hand on his hair, pushing him down but not much. She coo'd, satisfied with how he turned out, tracing her finger over his face.

"Ah, I think you've had enough."

"Yes my king."

Esau stood up, his cock erect and swinging in front of him. He could feel his balls churning. They were full, almost painfully bursting. He looked back at his two servants, who still bowed on their hands and knees.

"May I?" He asked.

"Of course. Teach them who they serve now."

He walked towards them, his hard talons clicking against the stony floor. "Sit up," he commanded them. They both sat up. Belial's face was eager to serve, but Naamah's was struggling to stay defiant. He smirked and stood in front of the succubus, his cock just an inch away from her face. His powerful musk made her blush, and her features softened though she resisted.

"Beg for it."

"Please master, I want your cock. I want to taste it."

"I like that. Master. It's a good word when you say it. Always call me master, both of you."

"Yes master," they both said in unison.

Esau grabbed Naamah by the horns, like a pair of handlebars, and rammed the full length of his cock into her mouth in one go. She gurgled and gagged, the cock visible as a bump on her throat. She was a succubus, and therefore used to such rough handling, but she she still looked up with pleading eyes. He began to throatfuck her, thrusting his cock with **** and speed like he would if he were fucking her cunt. He grunted as her succubi throat conformed to the shape of his cock and lubricated itself.

"Ah, such a good little succubus. You'll be taking my demonic virginity you know, heh-heh-heh!"

"Mphh mmph mmmmph mphmm!"

"Heh, don't talk with your mouth full slut."

He picked up the pace, thrusting in and out of her lips as fast as he could. He could feel her struggle with keeping up, and her sensations became overwhelming. She couldn't stop moaning, her pleading noises goading him to cum. And cum he did. He thrust hard a couple times, pumping his demonic seed down into her stomach. He egressesed his cock just before the last spurt, splattering jizz all across her face. Cum dripped down her hairline, down the side of her nose and around her panting lips, all down to her chin which dribbled onto her heaving breasts. She licked her lips, satisfied but not happy.

"What do you say after I gift you my cum, slut?"

"Thank you master for your gift." She bowed her head down slightly, her hands clasped together on her knees. He smirked, pleased with his ****. The sound of moist masturbating caught his attention. Belial had her hands buried in her snatch, furiously fingering herself.

"Imp, what do you think you're doing? Who told you you could touch yourself?"

"I'm sorry master, I just couldn't help myself..."

"From now on, you only purpose as my **** is to watch me fuck. You may never touch yourself unless I say so, and you will never cum, ever. Is that clear?"

She looked mortified, but she withdrew her hand reluctantly, obediant yet frustrated. "Y-yes... yes master."

King Excelcia laughed from her throne, pleased with the show. She herself has been touching herself. "How deliciously cruel of you! That ought to teach the little whores a lesson." She spread her cunt apart with her fingers, showing off how wet she is. "Now come here and show me what your cock can do to a real demon, ****."

It was thus that Esau lost himself to demonic pleasure, serving as his mother's most loyal advisor and personal fuck toy for the rest of eternity.
