Chapter 4: Your Bitch

Theo lay shattered on the damp sheets, his mind a blank static hum. Every nerve ending had been scorched raw, his body a foreign, exhausted thing. The phantom sensation of being filled and then violently emptied still pulsed through him. He stared at the water-stained ceiling tiles, trying to remember the person he was just a few hours ago, the boy who worried about textbook editions and quiz schedules.

That boy felt like a myth.

A warm weight settled on his chest, followed by the tickle of crimson and black hair. Lily’s face hovered over his, her cold blue eyes gleaming with undimmed hunger. She nuzzled his cheek, a mockery of affection. “Don’t you dare pass out on me, nerd. The night is young and your new equipment has a hell of a recharge rate.”

“I… I can’t,” he slurred, his voice hoarse. “I’m empty. That was… it’s biologically impossible to…”

“Tch. Mortal biology is a suggestion, not a rule.” She propped herself on an elbow, her breasts squashing against his side. “You’re running on demonic energy now. My energy. And I say you’re ready.”

He wasn’t. His body felt like overcooked spaghetti. But as he looked into her eyes, a treacherous spark flickered in his gut. She saw it. Her smirk was a predatory slash of red.

“Let me give you a little jumpstart,” she purred.

She leaned in, but instead of the possessive lick he expected, she opened her mouth. A thick, shimmering strand of saliva descended from her lips, glistening like liquid silver in the dim light. It stretched, unbreaking, until it tapped against his own slack mouth.

“Open.”

The command was soft, absolute. His jaw loosened obediently.

The drop hit his tongue. It was not like any spit he’d ever known. It was warm honey and electric current, a flavor that was somehow both metallic and sweet. It coiled down his throat and detonated in his stomach. Fire raced through his veins, a sudden, furious reboot of his system. The exhaustion vanished, burned away in an instant, replaced by a clawing, insatiable need. His heart hammered against his ribs like a trapped bird. His cock, which moments ago had been a spent and sorry thing, stiffened to an almost painful rigidity, the monstrous size she’d gifted him returning with a vengeful throb.

“See?” Lily said, licking her lips clean. “Succubus spit. Better than any of your little blue pills.”

Before he could process this new violation, she was moving. She straddled his hips, her back to him, and leaned forward, planting her hands on his knees. The world vanished, replaced by the immense, pale expanse of her back and the obscene shelf of her ass. Then she reached beneath herself, taking his thickened length in one hand.

“Now for the main attraction,” she grunted, and guided him between the crushing softness of her breasts.

They enveloped him completely, a hot, silken prison of flesh. The sheer mass of them was staggering, swallowing his cock in a valley of overwhelming pressure and heat. She began to move, rocking her upper body, and the friction was maddening. He could see nothing but the pale skin of her back, the shift of muscle, the jiggle of flesh transmitting through her entire form with each motion. The scent of her, musky and alive, filled his head.

It was over too fast. The aphrodisiac in his blood and the visceral stimulus short-circuited any semblance of control. A guttural cry was torn from his throat as he came, his release hot and shocking between her collarbones.

Lily didn’t stop. She sat up, turning to look at him over her shoulder, her expression one of casual ownership. His spend dripped down her sternum. She scooped up a glob with two fingers and sucked them clean with a loud, appreciative smack. “Mmm. Tastes like potential. But we’re just warming up.”

She shifted again, this time rising to her knees. She planted her hands on the mattress in front of her, presenting her ass to him like an offering to a god he never knew existed. The cheeks were impossibly large, a perfect, jiggling sphere of flesh. She began to move them in a slow, hypnotic circle, a twerk that was less a dance and more a geological event. Each clap of skin against skin was a miniature thunderclap in the quiet room.

She reached back and spread her cheeks, and he saw his cock, trapped in the deep, dark groove between them. The sight, the feeling of being smothered by that immense softness, the sound—it was too much. The fire she’d lit in him blazed anew, the need building to a devastating peak. He was seconds away.

“That’s it,” she coaxed, her voice a rough whisper. “Give it to me. All of it.”

As his hips began to buck involuntarily, she shifted her weight with practiced precision. One hand guided him, and with a slight, slick pop, the head of his cock was no longer nestled between her cheeks, but buried inside a tighter, hotter, unbelievable warmth.

His brain flatlined. She had taken him into her ass.

She groaned, a deep, satisfied sound, and began to ride him in earnest, her movements becoming shorter, more demanding. “Yeah, fill it up,” she grunted, slamming back against him. “Pump your fucking soul into my ass, Theo. Mark your property.”

The command, crude and possessive, shattered the last of his restraint. He came again, a second, seemingly impossible eruption that left him seeing stars, his body convulsing as he emptied himself deep inside her.

She collapsed forward the moment he was spent, her body draping over his like a warm, heavy blanket. She was breathing heavily, a contented sigh ruffling his hair. She nuzzled into his neck, then delivered a long, sloppy lick from his collarbone to his jawline.

“Listen up, dummy,” she mumbled into his skin, her voice thick with satisfaction. “That binding ring isn’t just a leash on me. It’s a claim. On you.” She lifted her head, her eyes holding his, their blue depths no longer just mischievous, but fiercely possessive. “I’m your new bitch, little man. Your new thicc ass succubus fuck slut. Got it?”

To emphasize her point, she waved a hand. A shimmer of dark energy coalesced around her neck, solidifying into a band of sleek, black leather. A simple silver O-ring hung from the front, glinting in the low light.

She smiled, a dangerous, beautiful thing. “Now you just need to hold the leash.”
