You share your gift with your roommate

You stretched your arms, feeling full of demonic energy and magic ready to burst out. You needed an outlet to let it free into the world. And that outlet was a mere couple of feet away.

You had sensed your roommate's presence in her bedroom, clear as day. But now that you concentrated on it, you noticed something else.

Her lust.

You imagined the other succubus' pheromones and your passionate noises had unintentionally had something to do with it, because you heard the distinctive heavy breathing you had heard before when you accidentally walked in on her masturbating. She seemed to be making an effort to conceal it, a futile attempt. And the sound of anyone engaging in a sexual activity was like music to your ears.

You walked out to her door, still in your nude succubus form, and attempted to open it. It was locked, unsurprisingly.

"Lisa, open the door", you asked, attempting the diplomatic route first. "I can help you. I can help you... in so many ways"

"Go away!", she cried out, the flickering noise of the ring in her index finger rubbing against her clit not clearly audible. "Just go away, Erin!"

You had no intention of doing so. You would liberate her from her mortality, just as you would with the rest of humanity.

"Lisa, I'm giving you a choice. You can open it, or I can do it myself", your voice came out more assertive now, yet you didn't raise your volume in the slightest.

There was no response other than the faster, harder moaning coming from inside the room.

"Suit yourself", you said, using your new powers to give you enough strength for a second to **** the knob open. Inside, you immediately saw your roommate with her back against the opposite wall, completely naked save for her small white bra, half removed.

Lisa was a cute half-Korean girl, with a friendly and respectful personality that people, you included, always found attractive in her. While not too stuck in the old ways like her parents, she always seemed to talk and act with a certain aura of decorum, so it was doubly surprising to see her in such a position.

"I... cannot...", she muttered under her breath, fingering herself as fast as she could. "I cannot..."

"You cannot cum", you finished for her, and she raised her head to look at you. She made no effort to conceal the way her eyes were glued to your enhanced breasts, but she didn't spare any attention for the rest of your body either. "I could make that happen for you"

"I... I am not a lesbian...", she professed, shyly. But the way her pupils had dilated upon your entrance left no room for doubt.

"Yes, you are. You always were. Deep inside, you always wanted to fuck women. To fuck me." You knew it wasn't true, Lisa was as straight as an arrow. But it didn't matter now. In this **** state, she didn't have the strength to deny it. She would believe anything coming for you.

"That's... That's...", your pheromones were flooding her nostrils, making her unable to think of anything but sex. Unable to resist. "That's true! It must be true! You're so fucking hot!". Her muscles released some of their stress, relieved as she fought her new reality no longer. "Now please let me cum!"

She was completely under your thumb now. If a straight girl like Lisa had fallen like that, you wondered what it would be like what it would be like with your girlfriend. Your tail-cock twitched at the thought, releasing a dip of precum.

"I will. As soon as you eat me out, pet." She immediately moved to her knees and crawled to you, eager to reach her long awaited orgasm. She didn't even seem to mind the submissive nickname you had given her.

Reaching with one of hands against your toned ass for support, and the other one still working her clit, her tongue jumped to your pussy. She flailed it around with little to no technique, a poor excuse for a lesbian. But you didn't fully care, your demonic nature allowing you to take pleasure even in such a sloppy oral.

Still, it wouldn't hurt to bring a little more to the table. Lisa was caught completely off-guard when your cock-tipped tail reached her pussy with precision and penetrated her with a **** and expertise she had never experienced from a male before. The moment it came in, you felt as if your eyes had just opened for the first time, welcoming to a new world of pleasure ready to be discovered.

She blurted out something incomprehensible, unwilling to leave your pussy alone for one second. You noticed the first signs of her corruption as her tongue thinned and reached farther inside you. Even from your point of view, you could see her bra straining to keep her inflating breasts, unprepared for such a drastic expansion. The rest of her body was improving in smaller ways, as her skin cleared, taking a reddish color. You could also feel the roots of her two horns pressing against your thighs, lengthening more with each second.

You could have held longer, but your desire to see your fully corrupted roommate overruled it. A wave of pleasure was unleashed as you came from both pussy and tail, allowing Lisa to finally get her wishes realized. Your cum completely changed her from the inside, both physically and mentally. It truly didn't matter who she was before. Now, she was a lesbian succubus under your control, and little more.

You removed your tail after the very last drop had been absorbed by her. Her long tongue rolled back into her mouth, and she raised her head to see you from below, with a look of pure love.

"Thank you, mistress", she said, sincerely grateful at the new life you had given her.

"I told you I would help you, dear". It was amazing to believe, but you were still horny after two sessions of wild sex, maybe even hornier than before. It wasn't just your succubus' nature. There was also something else, the anticipation of yet another conversion...

"Change back to your human form, Lisa. We're walking out." You assumed your own form, improved in so many places that it was almost unrecognizable. Lisa stood up, and followed your lead, leaving all but one feature left.
