The predator

Rita gasped, a powerful orgasm overcoming her as she finished her feeding. Her worm-cock surged out of her slit, proudly presenting its entire foot and a half of bulk. Several powerful jets of shadowy black cum shot out of the cock-hole, showering the grass in front of the girl. Where it landed, an audible sizzle arose, the corrupting fluid digging into the plants and insects, any life in the way. Making it all bigger. Reworking it.

Meanwhile, the body that had been Jimmy Harmon began to dissolve into useless protoplasm that soon evaporated into nothingness, leaving the boy's clothes and belongings.

"Well that's convenient," Rita said, still cheerful.

She felt incredible, the first worm-cock orgasm still rolling over her brain. Power surged in her muscles. Was this what "big dick energy" meant? It certainly felt that way. Deep power radiated off her worm-cock. Rita felt like she could lift a car over head if she wanted to and this feeling wasn't far from the truth.

Inside the co-ed's former womb, demonic mutagen boiled, waiting to be mixed with her new demonic boy-cum.

"Thank you for your life, Jimmy," Rita said with a bright smile. The boy's thoughts and memories flickered through her as she digested his essence. And his balls.

Next, Rita inspected where her cum had landed. Her massive worm-cock bounced and wobbled as she walks. The grass was growing thicker, its leaves darkening. There wasn't quite enough corruption in the cumshot to transform the organisms exposed radically, though Rita imagined it would be far more effective on a girl.

However, this all gave Rita an idea. She desperately wanted to spread this gift. To expose so many beautiful women to that which was disgusting and monstrous.

Rita searched in the grass until she found what she needed. Her hands seized upon an earth worm the length of her pinky finger. Her cum wasn't strong enough to create a true beauty, but what about that pit of wickedness inside. If only she could get the worm inside there.

Rita brought the small creature to her oozing cock-head. It thrashed about, trying to avoid being sucked in until several smaller tendrils emerged from the opening and pulled it deep. Rita felt it go up the length of her cock and into the pouch of mutagen.

The creature thrashed wildly as the mutagen infected its body. Soon, it's size increased dramatically, its form reshaped for a new purpose.

Rita's belly swelled, pregnant with her new little beasty.

More. She needed to find more. Rita found more worms. Slugs. A centipede. All of her "children" grew and transformed in her belly. By the end, Rita looked a few months pregnant, her belly full of unholy life.

She needed cover. Bending over, Rita began to put on the dead boy's clothing.
