Rae can't resist trying out her new pet

Rae grinned wickedly as Lola picked up right where she left off, jacking her new clit-cock furiously. She had done it, conquered her whelp of a sister. She wasn't quite sure how, or what it truly meant, but the changes she saw filled her with the most euphoric, perverse pleasure she had ever experienced.

The beast she watched below still had her gorgeous twin sister's face, but it was now contorted in an unholy snarl of out-of-control animal lust. Her body was also the same, minus, of course, the massive, smooth cock that she was violently stroking. Rae had always been aware that her and her sister were beautiful girls, but since this attraction to women was new to her, she was only just realizing how sexy her sister was. She had a whole new admiration for the exotic look that such mixed ancestry gave her and her sister. Rae could tell that her new Master had plans for this lovely creature she had helped create, but watching the debased act playing out beneath her clouded her thoughts with seething desire and wanton lust. She felt her Master begin to exert its influence, but then concede, seemingly content to let Rae indulge her new self for a time.

Without any hesitation, Rae flipped over her sister on to her back, and plunged her cunt onto Lola's towering shaft, sinking all the way down smoothly. Rae squealed with glee as her body lit up, the thrill of corrupting her sister coming back again in a different but just as wonderful form. Lola roared grabbing Rae by the hips and roughly shaking her body, trying to use her tainted sister as a means to jack off her new member. Rae giggled and moaned as she bounced frantically on the demon cock.

"How does it feel now, my goody-two-shoes sister? Where did all that planning get you, hm? All that playing by the rules. Now you're jamming your fucking hell-cock into your twin sister! You were so afraid of breaking rules, failing, falling behind. Such a little perfectionist. I freed you! You're not afraid of anything any more, are you?"

Lola didn't answer, grunting as she thrust up into her sister, her face still set in her animal snarl. Then she groaned long and loud, and Rae felt a massive gush of hot cum spray into her pussy. Her Master reacted with elation, devouring the rich seed that spewed into her. Even though she couldn't see it, Rae could tell immediately that this was not normal cum. She could feel her Master growing, gaining power from the corrupted ooze that was entering her in torrents. The sensation was incredible.

No sooner than she had finished cumming, Lola grabbed her dominating sister and threw her down to the bed, simultaneously jumping up and grabbing Rae's ass. She plunged her cock into Rae's slit, black jizz oozing out around her dick as she did so. Rae was fascinated by Lola's sudden increase in strength, finding that it really turned her on to see the kind of sex-fueled animal that Lola had become. Rae continued to egg on and talk dirty to her sister-turned-fucktoy, laughing and moaning as blissful corruption doused her insides time and time again.

After some time, both girls finally started to wear out, their demonically-enhanced bodies eventually needing rest. Rae's Master had consumed an ungodly amount of Lola's black corruption, and its power had grown magnitudes. Rae could feel its presence dwarf her own mind, sweeping her away in whichever direction its desires went. She was a **** to it now, like Lola was a **** to her new brutal, demonic nature.

"Are you quite finished?" Her Master's voice boomed sarcastically in her mind.

Lola had seemingly finished, emptying uncountable loads of sickly ooze into her sister, and Rae had been satisfied as well. At least, as satisfied as a corrupted worm **** could be.

Rae giggled. "Yes Master. For now..."
