Submissive Succubus Slut Sucks Sibling

Tina crawled up to her brother Matt on her hands and knees. He was also barely conscious, stuck in a torment of pleasure, unable to climax but so close to it that it was driving him crazy. Tina had to help him. Maybe a kiss would make his pain go away? "Tina? ...Wha-" she silenced him by locking her lips with his. Tina moans into her brother's mouth and lets her hands explore his body. Everything feels... So much! Tina feels Matt's stubble tickling her skin. His hot breath on her face. And she feels the burning need in her nethers. When her hand wraps around something hard and warm, Matt breaks the kiss and gasps for breath.

"Is this it? Is this what hurts?" Tina asks innocently while massaging his hard cock. Matt is unable to answer and just humps his hips against her. "Just relax big bro... I'll help you feel better." Tina begins to slowly move down on his body, planting kisses as she goes and stopping to look up at him as if asking for confirmation. His dick looks so big. So red. So angry. And his balls are so big and full... Tina jerks him off slowly for a while before bringing her face closer. She looks up and sees Matt staring at her with his eyes wide open in shock. "Maybe this is what I need to kiss to make it better..." She plants a kiss after another on his testicles as her writhes and spasms, before giving his dick one long lick and taking it all in. Matt throws his head back and moans loud. Tina is starting love all the little sounds and spasms her brother makes as she pleasures him. A little voice in her head tries to warn her. Something about this being wrong. But that doesn't really make sense since Matt is clearly loving this and another much stronger voice is encouraging her to do more.

"That's it little slut. Suck him off and drain him for all he has." Lilin has walked up to the siblings and squats down behind Tina. Lilin holds Tina's head with one hand, guiding her mouth up and down faster on the dick, while her other hand starts to play with her newest recruit's ass and pussy. Soon both the brother and sister are whimpering in pleasure. Tina with Lilin's fingers punishing her cunt and Matt with his sister's warm and wet mouth all over his dick. With Lilin encouraging her, Tina's mind and personality were slowly melting and being replaced. Somewhere deep inside her, her soul was screaming in terror, but her mind was on a pink fluffly cloud, feeling only pleasure and thinking only of more pleasure that she could experience by doing whatever Lilin asked her to. "You like your brother's dick don't you?" Tina took her mouth off his cock, just long enough to answer "Yes Ma'am." before getting back to work. "You're going to love what comes next. Make him cum with your mouth swallow it all."

Matt tried to push her away, realizing finally what was about to happen, but Lilin shut him up by moving up to him and sitting on his face. The young man's feeble struggle couldn't get her off no matter how much he kicked and pushed. Lilin was merely amused by the defiant struggle. "Don't worry Matt... I'll make it all better." With that, Tina doubled her effort to "help" her brother. "That's it! Make him cum!" Lilin encouraged her student when she saw that Matt's resistance was over. Tina could feel his balls tensing in her hands and she took him in as deep as she could. Warm cum was flooding her mouth and she moved one hand to rub her own needy clit as she sucked and sucked. She had had guys cum in her mouth before, but not this much. It was filling her up faster than she could swallow. She tried to get back up but Lilin pushed her head down hard and Tina could feel the cum going traight down her throat. And there was more. A rush unlike anything she had felt before was filling her up. She could taste his life. His soul. Tina climaxed again and again as she felt new power coursing through her. Matt's body began to show signs of the drain. His skin tightening around his bones as Tina sucked him dry. Literally. His struggle ended with a final violent spasm when he was completely spent. As Tina lifted her head from her brother's cock she opened her mouth wide to show it full of his cum. And a strand of golden light of his soul almost escaping her mouth before she shut it and swallowed. "All gone! Aaah!" Tina said happily, showing her empty mouth to Lilin.

Lilin studied Tina. The teenager still radiated an aura of innocence even after killing a man. Her own brother. Now she sat next to the body and rubbed her full stomach while giggling. A succubus masquerading as an innocent young woman. This should be fun. "Are you still hungry for more?" Lilin asked her. "Yes Ma'am" Tina replied happily, gazing at the few humans still alive in the bar. "Mommy taught me not to stop eating until all the food is gone..." For a moment Lilin was afraid that Tina still had some conscience left but her worries leave as she sees the teen start to rub her cunt as she thinks of her family. "Mmm... I wanna go see mommy and daddy again. Matt is gonna get lonely in my tummy, better to have everyone together." She may talk and seem innocent at a glance, but there clearly is a devious hunger inside Tina now. Lilin hugs her and Tina happily nuzzles against Lilin's breasts and sucks on them.
