A trip to your girlfriend's apartament

With your freshly corrupted roommate Lisa at your side, you picked the keys to your girlfriend's apartment and left your own building. You ordered the other succubus to have her way with your neighbor, a young psychologist called Anne, who you knew always had patients in her home at this time of day. Hopefully, you would have another two demonically beautiful women at your command.

But it was an afterthought compared to your true purpose. The hall looked deserted as you took the elevator upwards, tapping the floor impaciently as it took longer than usual. You had made this same trip countless times, after meeting your girlfriend months ago in a bar and discovering, shocked, that both of you lived in the same building but had never once crossed paths. You two had been almost inseparable since then.

The elevator door opened excruciatingly slow, your pussy already wet thinking of what Jess would look like as a sexy succubus. Right now, she was a petite, thin girl. She had her hair dyed of different colors since long before you met her, now going through her "silver" phase. This was only one of many ways she expressed herself, and you were constantly amazed by how confident and passionate she was, often letting her feelings make the decisions for her, never vacillating. While of course that had it's drawbacks, it was undeniable that it also had a bearing at how great she was in bed, often taking the lead and encouraging you to try out new things.

Well, it was you who had something new to show her this time. Although for the time being, you remained changed into the body you had before your transformation, to soften the blow for her.

You opened the lock to her apartment door, and were able to hear instantly the sound of the news coming from her bedroom TV. And, with your enhanced senses, her beating heart as well.

You told Lisa to stay behind and walked into her bedroom. Jess was in her bed, wearing only a baggy shirt and black panties, watching intently as you came in. She blew a sigh of relief when she saw you, then immediately tensed again.

"Erin. You are one of them", she said matter-of-factly, surprisingly secure in her words. Right next to you, the TV showed a reporter and her crew being ambushed by a group of Succubi and Incubi before cutting off to the studio.

"How did you...?", you began, looking at your body, which you believed to be identical, before she cut you off.

"The little mole in your neck. It's gone", she explained, calmly. Of course. You had hated that thing so much for years that you had unconsciously forgotten to put it back in, after it vanished during your beautification. "So stop this charade. Show me what you really are."

This had definitely not been going the way you had expected. You were still perplexed, and also a little proud, of how composed she was right now, specially after seeing on TV what your brothers and sisters could do.

You took off the clothes you had picked up before leaving, knowing well they would burst out if you changed while wearing them. You transformed back slowly, giving her the time to visualize every improvement of your supermodel-like body. Even though she had been more than content with your old shape, it was undeniable that you were orders of magnitude more beautiful now. You stopped just short of your demonic modifications, looking perfectly human except for one key difference.

She looked at you awestruck, taking a few moments to process what she had just seen. "I know that's not all. Show me everything", she repeated, this time less certain of herself, unsure of how she would react at what would come next.

You complied, losing all illusions that masked you as a human. While she had expected the reddish skin, horns and tail, she gasped when she saw the thick penis-head at its end.

"Don't let it scare you, Jess. It's still me, underneath, just under a much sexier package. Just as you will be" You paused, hoping she would be receptive to your message. You didn't care much for how your roommate had felt during her Corruption, but this was different. Even as a succubus, you still cared for her.

Your girlfriend was going through a deep internal conflict, but as it always had been, her emotions made the decisions. Two emotions ruled in her now. First, her trust. After all, she trusted you implicitly, despite everything she had seen and heard on TV.

The other emotion was more primal. She wanted to fuck your obscenely hot body until you passed out. She stood up and looked straight into your black eyes, uneavering. You had seen that look in her before. You smiled, knowing what would come next.

She closed the distance and tentatively touched your horns, curiously feeling their texture, before her hands went down to your soft cheeks.

"Come on, love. I want to see what my succubus girlfriend has in store for me"
