As Michelle awoke, head groggy from sleep and heart drunk on lust, vaguely she wondered what had happened to her. The tentacles had been so shocking, then erotic, that she had barely even had time to register what had caused all this. The lake, she realised. That feeling of something invading her body, the flushed panic she'd been put into as her body changed. There had to be something in the water that caused all of this.
She bit her lip as she idly dipped one of her tentacles into her sex again, while she stroked another. Two more wrapped around her hips and navel, slowly squeezing the supple flesh in undulating pleasure. Now that she'd had enough time to experience them, Michelle wasn't so displeased with her mutations. In fact, she was willing to go further. More changes. More freakish mutations. More pleasure. If that's what the water could give her, she'd take it all.
Picking up the limp pieces of tentacle she'd cut off, she took them with her as she trekked down the water's edge.
Michelle tossed the pieces of severed tentacle out into the lake and sat down on its shore. The water gently lapped at the entrance to her pussy as she spread her legs wide. Her four tentacles snaked out, seeking the virus-laced waters and diving eagerly into them. Suck, Michelle ordered them. And they did.
The tentacles began to pump water down their lengths. Michelle watched as they pulsed, 'swallowing' litres of water like it was nothing. And as she did so, she could already feel the virus getting to work.
Having already been altered by the virus, it was easy for it to take hold, and her transformation would be much faster. With each gulp, the tentacles began to thicken, swelling with muscle. Michelle could feel their power, now, as they grew stronger and stronger, stretching her pussy as they did so. Her hips cracked as they widened, her whole body growing thicker and larger in time with her tentacles. She surpassed 6 feet, then 7, then 8, stopping at a huge 10 feet of beefy woman. Muscles swelled to life on her legs and huge cinderblock abs adorned her chest as it heaved in and out. Her feet grew clawed as they too touched the water, and her legs took on the digitigrade appearance of a beast. Her eyes flashed red, even as the scarlet of the tentacles faded away to a dark ebony black. It was mirrored on her legs as her skin grew leathery and dark up to her waist, and two black horns grew from her temples. Michelle retracted her tentacles, each as big and thicker than her entire body had been beforehand.
She looked at herself - a huge, muscular beast that loomed over humans. Her claws dug into the earth as as snarled at her reflection, her bestial lower half and her sexy, yet indomitable human torso. Four thick, black tentacles lashed around her ankles, agitated by her sudden switch in personality, from a confused, shy girl to a sexy, dominant monster. Yeah, she would be the one in control now.
But she couldn't help but flinch as something thundered, shuddering the ground and spilling ripples across the surface of the lake. Something began to rise from its depths. Suddenly, Michelle was not so sure about her disposal method for those severed tentacles...
