Her Sister

Mallory pushed open the doors to the room and was met with a horrifying sight. Her sister and a bunch of other students lay in a puddle of their own cum, fucking each other. Clothes were scattered across the linoleum floor in random piles.

Mallory couldn’t move. She was paralyzed from the sight. Miles grabbed her arm and said something to her. Probably something about needing to run, but Mallory couldn’t understand what he said. She was trapped staring at her sister as she rode up and down on some guys cock. She was completely nude and her skin had turned pale like she had never seen the sun before in her life. The sight of it terrified Mallory, but also turned her on a bit.

The zombies then looked up at the humans standing still at the door. As soon as the fact that they were in fact humans made it through the zombies lust filled minds, they pounced. The entire orgy worth of zombies jumped at the group at once, falling over themselves to get to them.

Mallory slid out of the way of the first zombie that jumped at her, pressing herself against the wall of the classroom. Valerie wasn’t so lucky. She was grabbed by the first zombie that came at her, falling to the ground underneath him. Miles didn’t fare much better, as he was swarmed by a group of three zombies and fell to the floor under their combined attack. Mallory watched in horror as her friends began to be turned, unable to do anything as her friends succumbed to the same fate as her sister. There was nothing left for her to do. Her friends were gone and soon she would be too. Then to her horror, Mallory felt a hand close around her arm. Turning Mallory was faced with her sister’s blank stare.

“Mallory… I want your pussy, let me turn you.”

“No Jaime you’re sick, I need to get you help.”

“All I need *giggle* Is to fuck you. So why don’t you just give in to me?”

Mallory recoiled from her sisters touch. This wasn’t her sweet kind older sister anymore. This person wanted to fuck her and turn her into a zombie. Mallory pushed away her sisters hand, but then she felt something enter her pants. Her sisters other hand snaked its way under Mallory’s panties and towards her cunt. Mallory instinctively went to stop her sister from doing this. It was wrong to have sex with her sister. But then Mallory felt her sisters hand against her pussys outer folds.

And it felt wonderful. Mallory arched her back and let out a moan. She felt Jaime’s fingers enter into her and begin to stroke at her clit. As this happened Mallory began to feel her resolve weaken. Maybe it wasn’t a horrible idea to let Jaime do something to her. After all she was her older sister and probably knew best. And right now she was making Mallory feel wonderful. Mallory slowly began to give in to Jaime’s fingering. She heard her other friends also moaning out in pleasure as they had sex, each one of them having their minds blown.

Mallory was quite familiar with having her mind blown. Right now her mind was being flooded with pleasure as Jaime’s fingers pushed against her insides. As she did this, Jaime reached down to her own cunt, still dripping with the cum used to zombify her, and shoved her fingers into it. Taking her cum soaked fingers, Jaime shoved them deep into Mallory’s moaning mouth. Mallory licked the delicious cum from her sisters hand and let it drive her even further into her lust.

By now Mallory was close to cumming. She had ripped off both her shirt and bra and was letting her perky breasts bounce around. She could feel herself getting closer and closer to succumbing to Jaime’s finger fucking and couldn’t wait to become a zombie. Mallory was going insane with pleasure as her sister deep throated her with one hand and fingered her with the other.

Then, just as Mallory felt herself get ready to cum, Jaime stopped.

“No…..” Mallory moaned “Finish me.. I want to turn….”

Jaime just giggled and reached down grabbing Mallory’s neck. She pulled Mallory up into a sitting position and pressed her breasts against Mallory’s face. At first Mallory’s lust addled mind was too confused to understand what Jaime wanted, but she quickly realized. Jaime began squeezing her breasts, and a stream of creamy milk shot out. Mallory moaned as the milk splashed over her. The milk was warm and she felt it seep into her body as it covered her. Mallory leaned forward and put her mouth against Jaime’s massive breast. She began sucking on her tit draining her of all of her sweet creamy milk.

Mallory felt her mind exploded with pleasure as she was filled with milk. It poured into her stomach and filled her up to the point that she couldn’t take any more. Her stomach expanded until she looked like she was pregnant from all the milk inside her.

Then when she couldn’t take any more, Mallory fell backwards into the lake of milk on the floor around her. She felt her sister continue to cover her in the liquid and let her mind drift away into lust filled ecstasy.

Jaime had one last thing for her little sister to enjoy. Bending her sister over, she sprayed her milk into Mallory’s wet cunt, filling her womb with her hot liquid. Mallory screamed out as she was filled to the brim. Jaime’s milk quickly filled Mallory and began to spill out of her full womb. Mallory felt herself finally cum and turn, her juices mixing with her sisters milk and squirting out of her.

As this mixture of lust spiked out of Mallory, Jaime wasted no time in shoving her face into her sister’s gushing cunt to lap up the overflowing liquid. Mallory felt Jaime’s tongue lap up her insides as she swallowed load after load of her orgasm. Jaime consumed Mallory’s insides, causing her to black out in pleasure, collapsing in a heap in the sea of milk.

Jaime giggled at this and wrapped her body around Mallory’s, jaming their pussy’s together. Jaime felt liquid from Mallory’s continued orgasm enter her and it felt good. Jaime scissored with Mallory over and over again, each time bringing forth another stream of cum from Mallory’s cunt.

Mallory eventually woke back up and happily joined in with her sisters fucking. The two sisters reached down and began to finger one another on the floor, cumming over and over agin. They shared their wonderful zombie liquids with one another for hours covering each other in a thick layer of cum. They swallowed it, rubbed in on their breasts, and fingered it into their cunts.

The two meshed together into one writhing mass of lust on the floor, rolling around fucking each other in a lake of Jaime’s milk. Eventually the two got tired of enjoying each other’s bodies and went to go find someone else to have sex with and share their wonderful zombie liquids with. The two were the last to emerge from the room, the others had already turned and left. Mallory was weak into the legs and could barely stand up from the combination of Jaime’s fucking and her new over sized breasts. She left a dripping trail of liquid as she walked. She began to finger herself as she walked, cumming agin and again as she walked looking for someone else to share her dripping cunt with.
