Let them Turn Each Other.

Mara grabbed Mary and pulled her away from the two mortals. She looked like she was about to say something when Mara gave her a smile and shook her head. "We've infected them... let them bring each other over... it'll be so much more satisfying to watch," she said with a laugh.

"Oooh... I like how you think," Mary said as she kissed Mara. "Let them fuck each other to Hell."

Kara and Amber moaned as the Succubi pulled away. Neither of them had even thought about having sex with another woman, let alone each other. But the pheromones that had surrounded them and the infection from their two soon to be sisters in sin drove them. They were so far gone, their minds and bodies were begging for sex, and the only beings close enough to do it was each other.

"Fuck me... eat my pussy you slut!" Kara cried out, spreading her legs as she thrust her tongue deeper into Amber's hot pussy, the taste of her juices were driving her wild. "Make me cum! Make me a Succubus!"

Amber laid over her friend and rubbed her clit before thrusting in her tongue and two fingers, causing Kara to moan. The two women fucked each other eagerly as the Succubi watched, fucking each other with their tails. Kara and Amber worked each other over, their minds and bodies surrendering to the virus now running through their veins. Kara's fingers dug into Amber's ass as she stretched her tongue out as far as she could, eating her out expertly despite the lack of experience.

"Fuck..." Amber moaned as she lapped at Kara's pussy. She didn't even notice that Kara's tongue was growing longer, more serpentine, but shuddered when it brushed against her g-spot, then at another spot... it felt like her pussy was one big g-spot now as it became more and more sensitive. "FUCK!"

Amber's skin was turning golden as her hair turned a fiery red. Even in the 69 position, it was obvious to tell that her breasts were expanding outwards, forming perfect orbs as she ate out her friend. Meanwhile, Kara's skin was turning a deep red as her hair turned black. The two sluts no longer cared about what was happening to them, all they were focused on was pleasuring each other.

Kara screamed as she came hard, her back arching as two massive wings burst out of it. Amber's horns formed first, curling around her head as she moaned louder. Tails burst from their asses and snaked around, thrusting into each other's asses. They screamed in pleasure as their last demonic features emerged, where two sweet young women once were, now stood a pair of Succubi who pulled away long enough to french kiss each other.

"Thank you sisters," Amber said when she finally could pull away from Kara.

"We are perfect," Kara said.

"Good... good..." Mara said and smiled at Mary. "You two will bring so many new demons into the fold."

"We should go and find the others," Mary said. "We can hunt together."
