Mother

Mike smiled to himself as he strode down the hallway past his sister's room, he knew that the two of them would soon return for her. As he moved down the familiar staircase and into the hall Mike was excited that his incestual fantasy was finally to become a reality. Of course, the voices had gifted Mike by ridding him of inhibitions and so much more.

Whilst he had a human appearance, Mike knew he was far superior to them now. Stepping forward he moved out of the hall and into the darkened lounge where his mother sat in front of the box. Knowing now was the perfect time to strike, he idly stroked his erect cock and released a stream of the noxious goo. Once Mike had gathered enough he moved into his mother's line of sight.

A wave of terror ran across Susan’s face as she parted her lips to let out a piercing scream but was shocked when nothing came out. Taking his chance Mike stepped forward and thrust his palm into his mother's face. The veracious green goo covered his prey's face and Mike watched with morbid curiosity as the slime oozed between Susan’s stunned lips.

Mike found himself grinning as he watched Susan’s throat convulse as the cum slid down her throat and slowly her body began to shift. It was subtle at first, her tired auburn eyes shone brighter as she eased herself from the chair and gently scooped the cum from her face. A sly grin crossed her plumping lips as she hungrily lapped at the nourishing nectar that lingered in her palms.

No longer wishing to be defined by the clothes she wore Susan grabbed both sides of the dress and tore it in half. Mike grinned as he saw his mother’s voluptuous figure regenerate under his emerald gaze. Sarah purred wantonly as her former B cup breasts ballooned outward into a firm set of DD’s that rode high on her chest and released a stream of infected sludge from her erect nipples.

Mike moved forward with nothing but primal lust in his eyes as he grabbed his mother's head and pulled her lips against his. Both mother and son began to rut like animals in heat, as Susan’s body continued changing. Her formerly flat rear quickly inflated outward into a substantial bubble butt that jiggled with each minor movement.

Susan’s slick lips moved over Mikes's own with such ferocity that the two of them quickly fell to the floor. A low groan slid from the sluts lips as Mike lined his cock up with her slick hairless pussy. He showed no hint of remorse as he plunged into the cock-hungry slut before him. Mike no longer felt any emotion towards her she was merely another hole to fuck and soon she would bring others into the fold.

Waves of green cum erupted around Mike’s cock as he brought the newly transformed Susan to climax again and again. There was an audible pop as he pulled his hard cock from her slutty pussy and grabbed her by the waist before throwing her back onto the ground. Susan landed on all fours with feline grace as she parted her cum slick lips to speak in a husky tone; “Do it, son, stick it in my ass and fuck me like the whore I've become.”

Not needing further encouragement Mike obliged and rammed his cock up Susan’s virgin taint in one swift motion. More cum fountained out from her engorged cunt as it pooled into the carpet below. Grabbing her hips he rapidly slammed his cock into her time and time again as he watched her belly inflate until it touched the cum slick floor below.

With their carnal desires momentarily sated Mike pulled out of the newly transitioned harlot before covering her blemish-free skin in more of his corruptive seed. Susan giggled as she milked a hefty tit with one hand and rubbed her belly with the other. Mike found himself elated at the incestual act he had willingly committed.

Susan sidled up to her son turned lover and released a hearty giggle from her lips. Moments later she parted them to husk; “Well stud, I think it’s time we introduce Sara to her new improved family.” Mike snarls in response before speaking “I’m sure we can do more than mere introductions slut." Susan lapped at her cum slick lips as she and Mike left the desecrated lounge and started their ascent…
