Dark sisters on the Hunt

Rita admired her handiwork with pride. The girl was a near perfect specimen and the changes had manifested so quickly.

The monstrous fusion beast had disappeared between the folds of the little freshman's hopelessly stretched pussy with a final wicked pump, triggering an explosive orgasm. Rita remembered watching with glee as the light within the girl's eyes faded and her will broke. The poor little thing babbled below her as the worm inside seized control.

The physical changes had come on the girl so violently, making Rita's transformation seemed peaceful by comparison. The girl's perky little bee-stings swelled like filling water balloons, bouncing and jiggling as their weight increased. The girl's loose Spider-Man shirt soon became strained, lifting up to reveal a creamy midriff already rippling with sexy muscle.

Below the waist, the change was just as dramatic. The girl's tiny, pert ass surged into a luscious bubble butt that squeezed out of her athletic shorts.

Within less than a minute, Rita's brand new sister in the joining had grown into one of the hottest women she had ever seen. That's when she lost control. Rita dove down on the girl, caressing her large, wonderful titties and sloppily mashing her lips in a wet kiss.

The girl accepted the intimate request immediately, her body incapable of resisting the exhillaration of physical touch.

They rubbed up against each other, Rita taking off her bulky sweatshirt and the girl lifting her shirt to reveal her massive pair to the cool air. The feeling of their enhanced boobs bouncing against each other brought both former college girls to powerful orgasm.

But that wasn't enough, they needed more. They both furiously explored each other, feeling their supple, perfect womanhood.

Then the tentacles got involved. Rita's was the first to pop out. Her worm-cock slid out of her snatch and grew to a very full, throbbing erection. As she brought it to the girl's open slit, she got a surprised.

From the girl's slit erupted a monstrous slug like appendage glowing with every diseased color of the rainbow. From its surface sprouted dozens of smaller, gelatinous tendrils. The monster-tentacle wrapped itself around Rita's cock, driving tendrils down the hole.

At that moment, the two girls truly became one flesh. Their minds melded and Rita could suddenly feel herself drinking in the girl.

Her name was Eleanor Cabello, or El. She was such a strong girl, especially for the tragedy she had experienced. Rita caught snippets of memories. The wrenching impact of two cars colliding. Black roses falling on a casket as rain poured down from above. A rejection in front of a dozen curious middle school eyes.

Similarly, El drank her fill of Rita, delighting in the girl's power and relentless energy.

An orgasm she struck the two joined women, exploding like a nuclear bomb. In the searing heat and bliss, a permanent psychic connection formed between the two unnatural sisters.

El held tight to Rita, desperately needing to be so close to this woman that had transformed her body and mind so much.

Now Rita prowled the campus once more. Three more critters bulged within her, demanding women to fill, but she was starting to get hungry once more. Turning El had taken so much energy.

It had all been worth it of course. Her adorable little sister of lust had proven to be a neat perfect candidate for the joining.

Now Rita had to choose: continue spreading darkness or take a break to feed?

El skipped into her dormitory, reveling in the way her chest bounced with each step. She was filthy with smeared dirt and slime, but somehow, she managed to smell better than when she walked out of the door over an hour prior. Her whole body smelled of strawberries and honey.

From the RA Office at the center of the building, Jenifer Rogers stared in disbelief at what she was seeing. It Eleanor from her hall, but she was so...different. Since when did she have tits like that?

The regularly subdued girl seemed so perky and buxom.

El gave Jenifer a quick glance. She was a cute redhead with a pixie cut and freckles that dotted her face. Within El's womb, her monstrous appendage squirmed.

Not yet, she thought. El's mind was only on one person. Yuki.

El's womb did not boil with corruption like Rita's. She was different, and as a result could not create "children" quite like her older sister.

However, this was made up for by the fact that corruption oozed in every single facet of the girl's body. Her saliva, her breast milk which now filled each tit, her pussy fluid. Even more of the corrupting mutagen imbued the tissues of her monstrous slug-part. Each piece of that beast could reshape or separate from the whole to serve its purpose.

El was by now desperately hungry. After all, undergoing transformation took even more energy than transforming another. She didn't care. All El could think of was her delicious little roommate.

When El opened her dorm room to find no trace of said delicious little roommate, she was understandably pissed.

Rita stood at the corner of her dorm hallway, torn between two equally enticing options.

From down the hall, Rita heard the booming voice of Billy Feinburg, all star swim captain. She imagined the taste of Billy's big, fat balls sliding into her worm-cock. He could give her energy for days.

Meanwhile, in the study room to her left, she heard soft, feminine voices. The door was closed and the lights were off, but Rita could still sense the two female presences.

Time was ticking for a decision...

Yuki writhed in the bed. From her arm protruded an IV pumping a golden liquid into her bloodstream.

The black veins around her eyes had died away, but her body was still burning and transforming, albeit at a slower pace.

Ms. Nightshade hovered silently over the girl, her unnaturally pale brow furrowed. This was out of her element.

At her hip, she felt the vibration of her cell phone. Her contact had finally responded.
