There's no reason to fight anymore

"I want you to fuck me..." Mary moaned. "There's no point anymore, just make me a hot succubus already..."

Mara grinned, she didn't need any further prompting as she unbuckled her seatbelt and pulled Mary into the backseat. She grinned a bit, remembering her old human life where she had lost her virginity to her first boyfriend in the back of a car. Now she was going to take her first mortal soul in one.

She held her claws out and tore Mary's clothes to shreds, Mary letting out a moan as her breasts bounced out into view. She ran a hand slowly along Mara's horns, smiling a bit as the Succubus onyx horns.

"So sexy... so powerful..." she said softly as she gave her friend a smile.

"Just like you will be soon," Mara said with a fanged smile, her tail swishing behind her as she ran her claw along Mary's panties. "You're not going to need these anymore."

With that she cut the straps off the panties, revealing Mary's perfectly shaven pussy. Mara grinned a little at that a she licked her lips. "Naughty girl... you're going to make a fine succubus."

Mara pushed Mary down onto the seat and squatted over her head, pressing her pussy against the human girl's face. Her tail flicked out as she pressed the cock tip against "Eat my pussy, infect yourself, slut!"

Mary didn't need any more prompting, she pressed her mouth against Mara's pussy and plunged her tongue into it. Mara moaned as she felt the tongue press into her, fuck she was good at this, even Lynn hadn't been this good. She moaned as Mary's expert tongue slid along her pussy lips, brushing against her clit before pushing into her pussy. Mara moaned as she imagined what the girl beneath her was going to look like as a succubus. The two of them were going to make a fine pair.

Mara grinned as she thrust her tail into Mary's pussy, causing the human girl to let out a muffled moan as her tight pussy was penetrated. Mary had completely surrendered to the Succubus, the infection was already running through her veins. Mary no longer cared about her old life, her thoughts filled with images of succubi and incubi fucking. While being fucked by a man would've disgusted her before, her changing body existed only to dominate them, to control them.

Her tongue probed at the inner walls of her succubus lover as she felt the large cock tail filling her. The last of her silly mortal failing slipped away as her mind gave itself over to lust. She extended her tongue out as she pushed her tongue in as deep as it would go, lending moans from her succubus lover.

Mara squeezed her breasts and looked out the window only to see a man watching in shock from across the street. She grinned when she saw that his hand was wrapped around his cock, jerking off. She leaned forward and pressed her tits against the window and let out a cry as she cummed, her black juices covering Mary's lips as her cock tail Mary's pussy.

"Oh... fuck... mistress... I want to cum... I want to cum so badly..." Mary moaned as she pulled back. "Make me a fucking succubus!"

Mara smiled as she thought about it. She could return the favor on Mary, or she could get her to take the young man across the street. Mary's features were already ballooning out, her tits were now a respectable D cup and growing. She wanted to be fucked, but who would do it?
