Her Sister, The Bride

“HEATHER!” Katie gasped in sexual frustration, her mind raising alarm bells about how exciting it was to have her sister eating her ass. Katie couldn’t believe her sister had done something so shameless, and she wanted more!

Heather barely paused for a moment, starting to bounce up and down on Luke’s mammoth shaft looking at her sister with mischief before painting a trail up Katie’s chest and neck of precum with her tail.

“Here I thought you were the slutiest of us.” Heather remarked nodding in one direction where their brother Barnie was pinned between two succubi, rejoicing in the perversion of having a threesome with two sisters.

Katie felt offended by that statement, how dare her sister think that of all things.

How could she not be though?

“There’s more to being a slut than just fucking.” Katie remarked, she felt a twinge of panic and her heart skip as some part of her was mortified by the alluring tone with which those words were uttered, and just who to. “Its about being willing and easy.”

Katie grabbed Heather by the neck, firmly holding her sister as she bounced atop Luke’s cock. With one hand locking Heather’s gaze to Katie, Katie’s other hand set to work. It explored her sister’s smooth pink skin, cupping and fondling the bouncing succubus’s seemingly flawless features.

Her hands seemed to hesitate when darker more perverse thoughts tried to slip into actions. Like running a finger across Heather’s clit, or pinching her nipple. As if sensing this Heather’s body seemed to respond, Katie unable to help but stop her tactile exploration and look as she felt warm breast milk seep into her hand.

Not missing her chance Heather pulled Katie to a breast, smearing the lactating corruption in her sister’s face barely a moment before Katie’s lips took eager hold and drew long and hard.

Glaring up at her sister Katie wondered if suckling from her sister was truly perverse enough, her body growing in desire to resume its more active sexual role that had been interrupted when Luke had toppled over.

Shuffling into place over Luke’s face Katie was relieved to feel his tongue resume its acts upon her ever more depraved body as her mind raced with the notion of not just her first threesome, but one with her own sister.

Her mind started the think of what next she could do to push the taboo bar of perversion further, an idea floating in her head like a fluffy snowflake, winds of resistance fighting its slow gradual drift of touching down upon her mind from its ethereal source.

Katie’s chest still buzzed with electric pleasure and desire from the brush of Heather’s phallus tipped tail. As she switched from one breast to another she debated sucking it first. Wondering if her sister sharing the perverse object orally might encourage others to join their debauched threesome.

Her mind raced with ideas of facing her sister as they were double penetrated and used by a crowd circled around them.

Moving her lips up Heather’s body with urgent passionate kisses, Katie soon made out deeply with her sibling. Relishing the perversion of it, what few thoughts of morality emerging in objection icing the taboo with arousal as Heather’s hands danced across Katie’s naked body.

Breaking from the kissing to gasps and curse in a climax as Luke’s tongue pushed Katie over the point of another climax Heather took her turn. Tugging Katie’s head back by her raven locks, she unleashed added gasps and moans as her fangs nibbled on the unconverted flesh.

Heather delighted in having had the timing she did, she had originally planned to get to their brother first.

Pulling Katie’s ear close Heather whispered to her, husky tones of sultry promise carrying the succubus’s words into her sister’s lust and pleasure clouded mind. “I want you to do me a favour.”

Katie just moaned in response to the words, the nibbling on her neck adding to the arousal of any kind of want beckoning for her.

“I need you to give me your soul.” Pulling back from the passionate kissing Heather relished the perplexed look on her sisters face as she brought her tail around between them. Lapping at its tip with her long tongue in graphic phallic fashion Heather slowly drifted the cock tip toward her sister’s face, two entranced eyes following it despite a glint of fear and terror struggling to break free of its pleasure bounded host.

Feeling the cock tipped tail brush across her cheeks, under her chin, and up the other cheek Katie puzzled with the reaction trying to break free of her desire to just lick at and suck the perverse object.

“Why?” The simple word slipped out, Katie felt embarrassed and contrastedly resolute in the question. The small victory of her soul and what little resistant thoughts rewarded with the sudden ability to eagerly mouth, taste, and attempt to swallow the limb.
