Lustful Demon King: Summoned by the Demon Goddesses!-Chapter 64: Claiming Natasha - Part 4 ( R18 )

The lesson was brutal, a baptism by fire and flesh. Jax was a relentless, demanding instructor, and Natasha’s throat was his unwilling, yet pliable, student.

He showed no mercy, his grip on her hair an iron shackle, his hips a piston driving his massive cock deeper with every thrust. He ignored her choked sobs and the tears that tracked clean paths through the mess on her face.

Her struggles were pathetic, the weak fluttering of a captured bird, and only seemed to excite him further, his thrusts growing harder, more insistent.

"Breathe, you stupid slut," he’d growl, pulling back just enough for her to snatch a desperate, ragged breath through her nose before plunging back into the tight, convulsing heat of her throat. "Or do you want to pass out and miss the best part?"

The threat was real, and it was effective. Natasha, fighting for every gasp of air, tried to obey. She forced her muscles to relax, to accept the invasion, to accommodate the impossible girth that was reshaping her esophagus.

The gagging reflex, once a violent, convulsive rejection, slowly began to dull, transforming into a dull, aching throb of submission. The initial pain and panic gave way to a strange, numbing acceptance, and in that acceptance, the embers of her conditioning began to glow brighter.

The sheer, primal act of being so completely and utterly used, of being reduced to a hole for his pleasure, was a potent aphrodisiac. Her body, already rewired by his magical torture, responded with a traitorous, desperate eagerness.

The heat in her loins, which had been a low simmer, began to boil once again. Her neglected pussy, still swollen and sensitive from the toys, clenched rhythmically, aching to be filled.

A soft, wanton moan escaped her lips, muffled by the thick cock pistoning between them. It was the sound of a woman finding her purpose, not in saving the world, but in pleasing the man who owned her.

Jax felt the change. He heard the shift in her sounds from choked protest to guttural pleasure. He felt the subtle relaxation of her throat muscles, the way she began to push forward, greedily taking more of him.

A dark, triumphant smile touched his lips. The Hero was gone. In her place was a slut, and she was finally learning her trade.

"That’s it," he grunted, his voice thick with lust. "Take it. Take all of it. Show me how much you want it."

He increased his pace, the rhythm becoming frantic, his balls slapping against her chin with every deep thrust. He was close.

Natasha could feel it in the tensing of his muscles, in the way his cock seemed to swell even larger, becoming an impossibly hard, hot bar of steel invading her.

The thought of what was to come, of him cumming, of tasting his seed, sent a fresh jolt of lust through her. She wanted it. She needed it. It would be her reward, her final initiation.

With a guttural roar that echoed off the stone walls, Jax slammed his hips forward one last time, burying himself to the hilt in her throat. His cock pulsed, and then it erupted.

The first spurt of his cum was a shock. It was scalding hot, thick, and impossibly potent, blasting directly down her throat. It wasn’t just fluid; it was power, a virile, magical essence that seemed to seep into her very cells.

Natasha’s eyes rolled back in her head as a new, more intense wave of pleasure washed over her. This was different from the toys. This was real. This was him.

He came again and again, a seemingly endless flood of his hot, virile seed filling her stomach, her mouth, overflowing from her lips and dripping down her chin.

The taste was intoxicating, salty and musky and undeniably *him*. It sent her into a new, dizzying high of pleasure. Her body convulsed, not from a lack of air, but from a powerful, shattering orgasm that ripped through her without a single touch to her pussy.

She was cumming just from swallowing his seed, from the sheer, overwhelming pleasure of being used and filled by him. She gagged and choked on the sheer volume of it, but she didn’t pull away.

She swallowed desperately, greedily, determined not to waste a single drop of her master’s gift.

Finally, his convulsions subsided. Jax held himself deep inside her for a moment longer, his grip on her hair loosening slightly as he caught his breath. He slowly pulled back, his cock sliding out of her throat with a wet, slurping sound. It was still hard and throbbing.

Natasha stared, her mind reeling. It was glistening with a mixture of her saliva and his cum, but it was as erect and imposing as it had been before he came. It was impossible.

She knew, from whispered conversations and stolen texts, that men needed time to recover, that they went soft after orgasm.

But Jax was not a man. He was something else. Something more. A god. A demon. A being of impossible power and endless stamina.

The realization hit her with the force of a physical blow. He wasn’t done. The throat-fucking had just been the prelude. The appetizer. Now, she was going to get fucked. Truly fucked.

A fresh wave of terror and anticipation washed over her, her already overstimulated body trembling with a mixture of fear and a desperate, primal need.

Jax saw the shock and dawning comprehension in her eyes. He chuckled, a low, predatory sound. "Did you think we were done, little Hero? Did you think that would satisfy me?" He gave his still-hard cock a few lazy strokes. "I’m just getting started."

He grabbed her by the arm and yanked her up from the bed. Her legs were weak, trembling, and she nearly collapsed, but he held her up effortlessly. 𝗳𝚛𝗲𝕖𝕨𝕖𝗯𝚗𝚘𝕧𝕖𝗹.𝗰𝗼𝕞

He spun her around and bent her over the edge of the plush black bed, her face pressed into the silk sheets that still smelled of her own sweat and arousal.

Her ass, still glowing faintly pink from the magic paddle, was raised high in the air, a perfect, vulnerable offering.

"Please..." she whimpered, the word a muffled plea against the sheets. She didn’t know if she was begging him to stop or begging him to continue.

"Please what?" Jax taunted, moving to stand behind her. He ran the head of his cock, still slick with her saliva and his cum, along the slick, swollen folds of her pussy.

He teased her, parting her lips with the tip but not entering, letting her feel the heat and size of him. He pressed it against her clit, rubbing it in slow, agonizing circles.

Natasha gasped, her hips bucking involuntarily. The sensation was electric. "Please... I need... I need..." she babbled, her mind a fog of lust.

"You need what?" Jax demanded, his voice hard. "Beg for it. Beg me to fuck you. Tell me what you are. Tell me what you want."

He continued to tease her, rubbing his thick head against her dripping entrance, letting her feel the promise of the pleasure and pain to come.

Natasha was losing her mind. The teasing was more torturous than any of the toys.

She needed him inside her, needed to feel him stretching her, filling her, claiming her. Her pride, her identity, everything had been burned away, leaving only this one, all-consuming need.

"Please!" she cried out, her voice thick with desperation. "Please, fuck me! I need you to fuck me! Please, Master, I’ll do anything! Just fuck me! I’m your slut, your whore, just please... fuck me!"

She pushed her hips back, rubbing her aching pussy against his rock-hard tip, trying to impale herself on him, but he held back, making her beg, making her degrade herself further.

It was the final act of her submission, the moment she willingly abandoned her old self and embraced the new one he had created for her.

"Good girl," Jax purred, his voice thick with satisfaction. He had her. Completely. He positioned himself at her entrance, the broad head poised to breach her. "Now, take it."

With a single, powerful thrust, he slammed his entire length into her.
