You'll have to work for it

You let out a long moan as the succubus ate you out, her tongue pushing out against your g-spot while her claw played with your clit. You would have cummed hard by now, but the Demoness seemed to be purposefully stopping it.

"Please, please, let me cum! I need it! I need to become a succubus!" You begged. Your hands were cupping your breasts with an insatiable need to see them develop into the large pair of tits you had drawn.

Yet at that moment, she stopped and pulled out her long snake tongue from your vagina. She laughed as she came to face you, her deep black eyes staring at you in amusement.

"Oh, dear, you really want it, don't you?" Her tongue touched your lips, while you still hopelessly rubbed your nipples.

"Yes! Please! I'll do anything!"

"Indeed, you will. I could make you a succubus right now. But you have the potential to become something better than I could give you. More than you imagined."

You were a quivering mess now, your need for release flooding your mind. But the idea of improving even your own dirty thoughts brought forth some ambition that you didn't know you had in you. Ambition not to serve, but to rule.

"W-What do I need to do?" You asked.

"Let your own desires finish your corruption. Let your inner devil take over and destroy your old self. Take, don't beg"

Those words drill deep into your brain. You had imagined yourself before as a dominant, confident succubus, taking your roommate and your friends with you into your harem. If you intended to be that kind of woman, you needed to start acting like one.

"Take, don't beg" You smiled as you turned the succubus around with surprising strength, leaving you on top, and planted a kiss into her lips, your human tongue thrashing against her own.
