'Hayley' lets in her boyfriend.

Lilith opened the door and welcomed her host’s boyfriend in. “Took you long enough!” She said in Hayley’s high-pitched voice. The succubus was usually attracted to just about every man (being a creature that fed on their souls), but Alex wasn’t bad as far as those went. The short-cropped dark hair, slight stubble, and fairly muscular physique would be the envy of any woman. She would say that he was out of Hayley’s league, but then again the many hours of volleyball had given her an equally toned body.

Alex looked to his girlfriend with excited expression, then a quizzical one. “Are you bleeding?” He asked, pointing to the corner of his mouth. Lilith realized he was seeing a trickle of her blood-red slime, still running from her lips.

“Oh, no, I was just… drinking something.” She collected the small dribble with her finger, preparing to lick up the last evidence of her body’s possession. Then she got an even better idea, and extended the finger to Alex. “Taste it.” She suggested.

Alex, a little bit confused at his girlfriend’s behavior, reluctantly gave Hayley’s finger a slight lick. “Holy shit!” He exclaimed, the taste of the unholy substance filling him with arousal. He took in more of her finger eagerly. “What is this stuff?” He asked in surprise.

“Something you want more of?” Lilith answered his question with a question, laying a manicured hand on his chest. “Because as it happens, there’s something from you I want too…” She slid it down to his pants, which began to tent the moment he laid eyes on the new Hayley.

Like any man, Alex was putty in the hands of the succubus. By the time she’d finished her sentence, his hands were all over her. Little did he know that the girl he embraced in a deep kiss, the girl he pushed against the wall and made out with him, the girl whose tan skin he gripped with ****, was a predator, and he was the prey.

‘Hayley’ eagerly clasped her boyfriend’s belt, freeing his already painfully hard member out into the open. Lilith smiled as she felt the warm, solid length of a human dick in her hand, for the first time in a long time. The thought of being filled by the life **** inside of it made her stolen pussy wet. The two continued to make out, even as Alex slid Hayley’s shorts down her smooth thighs. Soon his fingers found her cunt slick with arousal.

“You’re being such a slut.” Alex said between kisses.

“I need you so fucking bad right now.” Lilith admitted, quivering slightly at the touch of his digits to her labia. She could feel more than just a simple need to feed; Hayley’s feelings for the man began to mingle in her mind. She had all of her host’s memories, not just those of hours of sweaty fucking, but also those of sharing meals, going on dates and watching movies curled up together. Hayley didn’t just have sexual desire for him, there was genuine romance as well. She took him by the hand and led him back to her bedroom, his dick still swinging around in the air.

While still making out, the two peeled off their clothes. Hayley’s shorts fell to the floor, and she tugged Alex’s pants the rest of the way off. The moment his shirt was off his chest, she’d pushed him down onto the bed, climbing between his legs.

“What the hell’s gotten into you?” He asked. His girlfriend had no small sex drive, but the woman now throwing off her tank top seemed someone else entirely.

Lilith chuckled at the hidden reality of his comment. This was the first time she’d seen Hayley naked too. She took a brief moment to grab her own breasts, feeling her host’s decent size before her gaze naturally wandered back to the cock before her. Licking her lips, Lilith prepared to mount the waiting Alex. She teased his cock at the entrance of her pussy for only a brief moment before slowly sinking down.

Alex let out a grunt as his girlfriend impaled herself on his meat. “Fucking hell, it’s really warm inside you!” He groaned. Unnaturally warm.

‘Hayley’ only replied with a moan she began to grind on his dick. Lilith pressed her hands down on his chest, savoring every inch of him inside her stolen body. The unaware boy grabbed his possessed girlfriend’s own chest, teasing her nipples with his thumbs as she rode him.

“Aaaah, this feels fucking amazing!” He exclaimed again. “Shit, we should’ve closed the door, shouldn’t we?”

“It’s ok.” Lilith breathed, not slowing down for one minute. “Emily isn’t here.” She gave a perverse grin, knowing the empty shell of the girl lay inches under the bed. She rode him even harder, slamming herself down on his dick with every bounce. Every inch was heaven to her. Already she could feel the precum seeping into Hayley’s slick canal, giving her a boost of unholy energy and bringing her closer to a human orgasm.

Soon enough Alex told her what she already knew. “Shit baby, I’m close!” He tightened his grip on her boobs, as if trying to concentrate on something other than his dick.

“Me too!” She moaned. “Give me your cum, baby! Give Hayley your cum!”

“Aaaaaah fuck!” He grunted, and Lilith moaned louder than she had in years as she felt the cock deep inside her erupt furiously. Her eyes rolled back in her head, her tongue lolling out of her mouth as she felt the simultaneous sensations of the Asian girl’s orgasm and cum being pumped inside her. The false Hayley relished the feeling of rope after rope of hot semen blasting into her, and she fed on it eagerly. Alex was in the throes of his own extended orgasm, not knowing that his own life **** was being milked by the hellish demon infesting his girlfriend. He became weaker and weaker by the second, until soon his vision became dark. The last thing he saw before passing out was the satisfied face of his girlfriend, scarlet goo dripping from her stuck-out tongue.

Having sufficiently fed on the man below her, and with Hayley’s orgasm subsiding, Lilith willed the dick inside her to stop cumming. She could have continued to feed on Alex until he was emaciated—or dead—but the succubus stopped herself. Maybe Hayley’s feelings for him had affected her judgement, or maybe she was growing a conscience. Either way, she licked up the drops of red slime on her breasts and stomach that had escaped her in the heat of the moment, and climbed off the passed-out Alex.
