Make it a Demonic Den

Heather continues to fondle and play with herself as you think over your next move. You could very easily enthrall the club's employees if you put your mind to it but the act of transforming Heather from a frail mortal to a lusty demon has given you a thrill that you weren't quite expecting. The thought of doing it more excites you and your smile widens as you imagine the club staffed by nothing but your loyal hellspawn. You see a pair of boots and toss them onto Heather's desk.

"Put those on and I'll show you how to hide your appearance, we have more personnel changes to make." Heather stops pleasuring herself as the boots land.

"Of course mistress, whatever you command!" She dutifully pulls her boots over her hooves and you begin to show her how to glamour herself to appear human. She has a harder time of it than you but that is hardly surprising given the difference between the both of you. Soon she is able to project her former appearance, albeit younger and sexier which is a somewhat vain decision but far be it from you to deny your minions sin.

"Now bring your girls to me and soon this club will be a far grander den of sin than you could have imagined." Heather does so dutifully, pulling her girls to her office one a time. With every one that arrives you repeat the process of corruption, some last longer than others but eventually all of them submit to you. As the number of succubi in the club grows so does your power as well as that of the sinstone's. As the last girl opens her now demonic eyes you look to the stone and smile. It is larger now, it can barely fit in your palm, and the dull purple crystals have grown in rough patches off of it and practically shine. Once the club is closed you know the time is perfect to plant it.

You continue to watch throughout the night as your new converts pleasure the clients in new and fair less tame ways, you wish you could join in but this moment is too critical for you to risk anything going wrong now. Eventually the club closes and you walk to the middle of the building, calling your minions around to watch, and embed the stone in the floor. After a few seconds the stone is seemingly swallowed up by the ground and followed by a seeming nothing.

And then the building begins to change. A mortal would never see anything different but your demonic eyes can see the truth. Everything in the interior of the building begins to warp to the appearance of the stone, dominated by blacks and purples. An altar of polished black stone and glowing purple crystals forms where you first embedded the stone, a direct link to your Mother's power. You rub your hands against a large pentagram carved into it's face and it glows violet.

You know exactly what you're going to do with this.
