Sister

Mike smiled to himself as he strode down the hallway before coming to a stop outside his sister’s room. His eyes darted across the faded wooden sign that read Sara, Mike felt nothing for the girl within not anymore. With a feral grin plastered on his lips, he grabbed the handle wrenched it to one side, and slowly stepped into the room.

Once inside he turned towards the thrumming music and could see Sara with headphones. Sara's eyes were fixated on the glowing screen before her and Mike knew Sara had no idea she was no longer alone. With newly acquired grace he moved silently across the floor behind her and gazed at the video she was watching. Mike’s eyes widened in desire at the sight of a horny degenerate thrusting into a girl on the screen.

Lustful predatory thoughts ran through Mike’s fevered mind as he grabbed Sara’s headset and threw it onto the ground. As the sound of amorous grans flooded the room, Sara turned around only to be greeted by her brother’s manic stare. A cold chill ran down her spine as he grabbed a fistful of her bright blonde locks and yanked her onto the ground.

Sara looked horrified as she tried to pull herself from Mikes's grip but found him too strong. With one swift movement, he pulled Sara’s lips closer to the tip of his oozing cock. A crazed look glinted in Mike’s bright emerald eyes as he thrust his slick cock forward. Sara moved swiftly to one side and narrowly avoided being speared by her brother's cock.

Not wishing to be messed out with his prey any longer Mike firmly wrapped his sister's hair tightly around his fist. Unable to move Sara looked up into her brother's eyes and saw nothing, in that moment she realised his intentions and gasped in horror. Seeing an opportunity Mike thrust his cock forward and down into his sister's throat.

A loud groan slid from his lips as he watched Sara’s throat distend around his mighty cock. Cum oozed out from every amiable hole as he savagely rutted in and out of the girl's lips. As the cum flowed down into her welcoming stomach, Sara’s eyes snapped open her pupils shone a luminous emerald. Both of them were now in-tune with one another as the newly transitioning Sara brought her plumping lips up to the hilt of her brother's cock.

Cum oozed out from between her whorish lips as Sarah eagerly deep throated her incestuous lover's cock. Neither of them spoke as they reveled in their primal lusts. Mike could feel Sara's tongue lap at his slit for more of his seed. Wanting to push the slut to her limits he pushed her away from his cock before parting his lips to snarl; “Strip and spread them, sister.”

Sara giggled light-heartedly as she grabbed her t-shirt and pulled it apart to reveal her bronzed flesh. Drops of greenish pre-cum oozed out from Sara’s sickening folds as she stood up and pushed Mike down onto the carpeted floor before pouncing onto his erect shaft. Copious groans slid from her lips as she caressed her breasts and purred as they inflated before her eyes.

Streams of infected milk leaked from the erect nubs of her EE cup breasts as they jostled enticingly on her voluptuous body. Mike coated the whore cunt lips with his seed as it tightened around his member like a vice and milked it for more of its corruptive nectar. Another groan slid from her lover's lips as she felt his hands wrapped around her plump cheeks.

Her mind ran rampant with thoughts of his cock sandwiched between her pert cheeks as another orgasm gripped her body. Cum splurged out between them as it coated the floor below. As they finished their primal rut Sara ran a hand across her newly engorged belly as she felt the parasites moving within her.

Neither sibling spoke as they eased themselves from the floor and began to walk towards the door. Cum slid down their enhanced forms as they moved down the stairs and headed to the lounge where their mother lay. Sara giggled before speaking in a husky tone; “I can’t wait to taste mummy’s cunny whilst you take her from behind stud.” Mike dropped his newly transitioned slut a dazzling smile before roughly grabbing her rear and pulling her in for a swift kiss.

Mike savoured the taste of his cum on Sara’s lips as he readied himself for what was to come…
