Danni

Danni snarled wantonly as she relinquished her grip from her father's muscular form and began to stride toward her brother. With each step, she made sure to accentuate her lithe figure and prominent DD breasts. Chris's stare was glued to his demonic sister as he felt his cock rapidly harden within his boxer's. Danni grinned as she reveled in the wrongness of it all and knew that soon he would become a mighty incubus.

As Danni gazed into Chris's eyes, she heard the heavy footfalls of her Daddy and looked around in time to see him charge past and grab Jenny by the hair. A terrified scream tumbled from her lips but was ultimately cut short as Max pulled her lips atop his cock and thrust his titanic member down her throat. Danni snarled wantonly as she strode forward and placed a hand on Chris's back before pulling him in for a heated kiss.

Seconds later, Danni eased back and cackled as she watched her brother's lips curl into a dazed smile. Looking down, the assertive succubus noted her elder sister's throat was heavily distended by the monstrous cock that was being roughly pounded between her overstretched lips. Cum sprayed out from between them as her Daddy roughly held Jenny in place by her auburn locks.

Danni purred as she raised a taloned hand before slashing away the denim jeans and cotton boxers her brother had worn that day. A coy grin spread across her sublime lips as Danni eagerly eyed up the cock that stood proudly erect before her. Chris groaned as a bead of pre-cum oozed from the tip of his cockhead.

Knowing time was on their side, Danni eased her brother against the wall and slid a taloned hand around his cock before slowly stroking it whilst leaving gentle kisses on the nape of his neck. Chris groaned in blissful orgasmic delight as he looked over Danni's shoulder and eyed his father roughly facefucking his sister.

As he gazed forward, Max growled softly before pushing his daughter away from his mighty cock and unleashing a torrent of cum atop her face. Jenny threw back her head and cackled maniacally as she greedily lapped the ichor from her carnal features. Chris came again as Jenny looked over her shoulder and eyed her brother up with her new serpentine stare.

Chris noted his sister's newfound predatory stare as Jenny eased herself up and parted her plumping pitch lips to mewl; "That's it, Daddy, take me up the arse, I want to enjoy Chris's transformation into a real beast." Max's timbre laugh echoed around the room as he roughly threw his whorish daughter onto the floor. Jenny purred as she landed on all fours, taloned hands and feet broke her fall as she groaned in debauched pleasure as Max's cock thrust deep up into her tight arsehole.

Danni purred as she turned away from her enraptured brother before sliding down onto all fours and pushing her bare arse against his slick swollen cock. Jenny moaned as she parted her pitch lips to snarl; "Come on Chris, follow Daddy's example and fuck your satanic sister." Chris needed no further encouragement as he felt the heat radiate off of Danni's divine cunt.

Roughly gripping her thighs, he plunged his cock up her arse, the succubus mewling delightedly. Jenny grinned as she roughly grabbed Danni's cheeks and pulled her in for an incestuous kiss. Both of them enjoyed the passionate embrace until Danni pushed her slutty sister aware and admired how her eyes became pools of crimson whilst her pupils expanded into pitch serpentine slits.

Jenny growled in delight as rows of fangs unsheathed themselves from her jawline. Cum oozed into the ruined carpet below as her predatory eyes darted up and saw the flush crimson skin that adorned her brother's muscular body. Chris growled as he slammed his enlargening cock in and out of the mewling succubus below. Her cock-tipped tail squirted another load of her corruptive seed into his bulging form.

Danni mewled in delight as she caught sight of her rapidly transforming brother within the reflection of Jenny's slit predatory eyes. Stream's of cum oozed out from Danni's butt as Chris's roughly clenched her pert bubble butt cheeks for leverage before pistoning in and out. A frenzied moan fell from the demonic harlot's lips as she felt Chris's newly formed tail-cock slither between the folds of her slick cunt lips.

Soon the siblings were nothing more than an orgy of crimson flesh. Chris roared as two leathery bat wings erupted from his back that coincided with his sisters. Jenny mewled in sordid delight as she felt the ram-like horns push out from her forehead as she noticed the same poke out from beneath her brother's newly formed pitched mane.

Jenny watched as Chris's thrust came to a halt as his predatory eyes darted over to the corner of the room at something she was unable to see. After a few moments, the demonic foursome heard a truly tantalizing sultry voice ease into their newly enhanced ears; "I'm so glad that Max and Danni introduced me to Mistress Natalie, she's a great lay. Now, who wants to take mummy for a ride?”

A crescendo of wanton snarls followed as Max roughly grabbed his wife's pitch mane and threw her into the middle of their incestuous orgy. The formerly prudish mother looked overwhelmed with joy as she felt her son's cock in her rear whilst both daughters lovingly lapped at her expanded GG breasts. Mistress Natalie's predatory eyes fell upon the incestuous demon's she had created as their orgy began anew.

Leaving them to catch up, Natalie sauntered over to the window. As she casually eyed up the suburban neighbourhood below. A wild grin spread across her lips as she heard the chorus of animalistic grunts echoed throughout the house. Casting her predatory gaze over the rooftops, Natalie wondered what she and her newly demonized family would set their sights on next…
