Fucked into a puddle

Poor Cynthia didn't have time to scream before her kids were on her. And soon, screaming was all she could do. The werewolf. Alice. Her daughter. It was on her, suckling on her breasts and grinding against her. The snake-daemon brought both of his dicks out and soon was fucking his mother and sister at the same time. The daemons didn't give her time to rest either. As soon as her cunt was flooded with cum, they simply changed position. Soon Cynthia was **** to drink the cum spilling from Alice's cunt while Jamie began to fuck her ass. And it felt so amazing. Her sensitivity still ramped up, every thrust of the twin dicks inside her, every caress and kiss... She was drowning in pleasure, and eventually she gave up.

Alice and Cynthia together sucked off Jamie, cleaning his double cocks from their own juices and then guided him back in. When the succubus and the hellhound joined the corrupted family, they welcomed them into an orgy of depravity. More and more daemon cum was pumped into Cynthia or spilled over her, covering her fully. It was when she was riding Jamie, both of his cocks in her cunt, the hellhound fucking her ass, that the change finally happened. Her mind had melted from all the pleasure and her body overloaded with corruptive cum. Her brain was all fireworks as she started to cum and she was only vaguely aware of how the ground seemed to rise to meet her. As she fell on the floor, her shape was covered in black cum, and then it melted down. A pool of dark liquid that spread around...

...and then began to gather again as a new form rose. The dark colour faded away into light blue and seethrough as she was transformed into a slime. A glowing core was visible deep inside the being and some humanoid features like her head formed again. As did massive breasts on where her chest would have been. Only then she remembered to add arms as well as Cynthia the Slime began to giggle. "Ooh. Let's see what I can do now!" She tried to stroke the hair on the hellhound that observed her with curiousity, but the arm would lose shape and become gooey again. "Teehee! Let's try that again!" This time she brought her hand to the massive red cock of the creature. It again lost form, but this time it enveloped the cock and she began to masturbate the creature. "Oooh, I'm like your personal fleshlight. Wanna try it son?" Jamie brought a cock to her face and Cynthia began to suck it. Then she had an idea, and grew a second head so that she could suck both of his cocks at the same time. It felt strange being able to do this. But she was quickly growing to love her new abilities. It didn't take long for Jamie to cum inside her. The black cum visible through the slime body before being absorbed by it.

Cynthia saw the succubus and the hellhound leaving. "Enough playtime, go spread Lilith's gift to others" it ordered them.
