Daughter

Your mother's grin grows wider. "I think it is time to teach that slutty daughter of mine a lesson. How to really be a bad girl. Mmmmm... And then, she can show her father what she learned. After all, you taught me the joys of ****, it is only fair that we give your sister a chance to indulge in it by corrupting her daddy..." Your cock presses hard against your mother's hips and she reaches between your bodies to jerk it. "Mmm... She is a fuckable little slut but I am thankful that you came for your mother first. Teehee..." You lift the teasing succubus slut up and lower her down onto your cock, fucking her against the kitchen sink. For a while, the two of you enjoy more of this unholy bonding between mother and son but you can't risk your father or sister hearing the sounds from the kitchen, so you pull out from her.

"Awww... Mommy wants more." You chuckle. "There is time for that later. Now, it is your turn to spread the blessings of our mistress Lilith." She nods and a new hunger is clear in her eyes. "No rest for the wicked." You follow behind your mother as she sneaks through the house to your sister's room. Luckily, as your powers seem to grow over time, you find a way to create a bubble from which no sounds can escape and you place it around your sister's room. This power is sure to be useful later, you think. Your mother puts on a glamour and you grab her from behind. "Remember, you belong to Mistress Lilith..." "Yes..." She replies and nods. You pull your bodies tighter against each other. "You serve Lilith, and you serve me." She moans and grinds her ass against your hard cock. "Serve well and you will be rewarded. No regrets. No weakness. No mercy." She leans back to kiss you and her tongue wrestles yours. "Just sit back and watch me. Master." She winks and leaves you.

For a while you simply wait outside. Though muffled for the mortals, you can hear your mother and sister chatting inside. Your sister Rhonda has had trouble with some boys and mommy is there to help and guide her. Soon they go from just talking about boys to choosing clothes for Rhonda to wear. You hear Rhonda moan as her mother teacher her to kiss. Finally unable to just wait outside, you turn invisible and sneak in. Rhonda has her back to the wall and your mother making out with her with such enthusiasm, that you wonder if the invisibility was even needed. She wouldn't notice if the house was on fire. "Ah! Ah! Mom!" Rhonda writhe's in her grasp as your mother begins to kiss her neck and trail kisses and licks lower and lower. "Stop... No... This is wrong!" The corrupted mother brings Rhonda onto her lap and spreads her legs, a show for your pleasure as well. "Are you sure you want -smack- me to stop?" Caressing hands make the teenager squirm and moan. "I- Stop-" A hand slides between her thigs even as Rhonda tries to close her legs again. "Don't!" A kiss on the neck. Rhonda shuts her eyes, clearly too shocked by the treatment to know what to do. The hand goes under her panties and the fingers find her G-spot. "AH!" Rhonda's eyes are wide open and her body tenses up. "Don't stop!"

You watch as Rhonda's own body betrays her. Her hips moving in rhythm with the fingers. She finally looks at her mother and rather than fighting back, she leans in to kiss her again. Soon clothes are discarded and Rhonda buries her face in her pillow as her mother is eating her out. She can't see her mother discarding her glamour and with the unimaginable pleasure she is experiencing, it takes a while for her to register that the tongue that is fucking her is longer than humanly possible. "Mommy! Mommy! FUCK ME!" She cries out again and again into her pillow. When she finally shudders and looks down, the sight of the crimson demoness going down on her, simply makes her cum again. Rhonda hangs onto her mother's horns and rides out her orgasm. The corruption spreading inside her begins to manifest. Her breasts growing into same massive mammaries her mother is now sporting. Her hips widening. Hellish red colour taking over her once so pale skin. Mother and daughter embrace and kiss. This time the mother hungrily devours Rhonda's soul and sends it screaming to Lilith.

The succubi finally notice you standing next to the bed and Rhonda bites her lip, staring at you up and down. "Bro... Gimme that cock." You happily oblige her and your two sluts take turns deepthroating it and sucking on your balls. For a moment you wonder if you should take your sister's virgin cunt or to spare it for your father, the thought of that taboo being broken is -almost- hot enough to be worth waiting for your turn.
