You walk down the aisle of various magic artifacts. So many catch you eye, but none so more than what appears to be a pair of female feet on the shelf. "What the hell?" you say to yourself as you approach the pair. As you get closer, the toes start to wiggle, almost like the feet could see you and react to your presence. You reach out and touch the top of the left foot. It is smooth, absolutely no hair on either foot, and they feel warm, as if they are actually alive. You pick both up and examine them better in the light. You can see they are tan and a light pink on the soles. Just for the heck of it, you smell them all over. Despite being a pair of feet, sitting on the shelf for who knows how long, they actually don't have a scent. They don't smell good or bad, they are scentless.
You look them over for a minute and smile. "Hell, these are perfect for me." you say. You've had a foot fetish for a long time, and these eager, wiggling pair of feet would be perfect for you. You take them to the front desk to purchase them. The elderly man behind the counter turns and sees what you have in your hands. "Ah, finally I can sell those things." he says with a sigh. "Pardon?" you inquire. "Let me tell you about those." he begins to explain. "Those feet were once attached to my mortal nemesis, a young witch named Black Rose. She was highly powerful with the dark arts and was able to stop men in their tracks using just her looks alone. In my younger years, I went to vanquish her after my friend was nearly killed. Along my quest, I learned that she is able to use magic, because of her feet; so using my less refined magic skills, I magically severed her feet from her body. She was no longer able to use magic and I killed her, but her feet still live. I could never find a way to kill them, they're completely invincible. So I figured since even though they are full of magic they are just a pair of feet and are harmless. Hence why I put them up for sale." he told.
Usually a story of that length would bore you, but his just made you want to buy the feet even more. "I'll take em!" you proudly proclaim. The old man smiles and rings up the till, which you proudly pay. "Oh, and here." the man hands you a large bag full of stuff. "All of Black Rose's footwear is in this bag. I don't know why I kept em, but they're yours now." You thank the man and go home with the bag of footwear and the witch feet. "I can't wait to go home and do some stuff." you perversely chuckle. "Especially since these feet are invincible, they must be eternally youthful and maybe even immortal too." So, you head home, maybe even faster than before. Once there, you walk in your home and....
