"How dare you?", she exclaimed.
"Well, my parents were killed twenty-four years ago and I was looking for the most worthy prey deserving my wrath. Guess what: that's you!" I replied.
"I will..." she started.
"...not do anything." I completed her sentence, "You have none of your powers here and you won't remember anything after returning to your domain."
"Anyway. I've used the best part of my life until now to get you here, now I have to make sure, that I can get you back here on easier terms anytime I want."
"What?", she asked irritated.
"Enough chit-chat," I said, stepping towards her, and removing some leather utensils from my belt. Throwing her to the ground and pulling her hands on her back, I whipped the wrist straps above her hands and connected the two. Then I did the same with the ankle straps and her feet.
"I will rip the soul from your body, you worthless piece of shit!" she screamed, wriggling in her bonds.
"Yeah sure," I replied playing unimpressed, pulling a large ball gag out of the box behind me. She was in no position to prevent me from gagging her.
"Two rings to enslave her," I said pulling out two golden rings covered in runes. "These are the pinnacle of my work. Kept near to your body, they will allow me to call you here upon my will."
Annoyed she squinted at the runes.
It took me a while to find a solution for the near-to-your-body-part, but I've come up with a perfect idea: I'll be piercing them to your nipples.
Her eyes widened in terror. She managed a muffled "Noooooo" through the gag.
"No worries. I have devised a plan, for how we can manage professional handiwork despite the rings being nearly twice as thick as the usual nipple-piercing.", I explained.
Grabbing her red mane, I pulled her over to the gyn chair in the corner of the room.
"Let's lose the unneeded clothes." I pulled down her g-string, then went the bra. I let her keep the thigh-high boots and the elbow gloves because nothing is more appealing than an otherwise completely naked woman with these still on.
Seating her on the chair, I opened the wrist straps pulling her arms to the lower sides of the chair's back and reconnecting the behind it again. Then I opened the ankle straps and put her feet on the leg-rests, using velcros to pin them in place.
Then, I tipped the chair to the back, putting her in a near-lying position with her feet in the air and her legs wide apart. I finished by taking her arms and arcing them under her to put them at a nearly 90-degree angle to her back. I fixed them with a rope and appraised my handiwork: her breasts were pointing upwards in a most beautiful way.
"Now to the bad news," I said. "As the rings are thicker than usual, the piercing needle needs to be a lot thicker, too. This might sting a bit." --- "Just kidding, to be honest: this will hurt like hell."
"Because of that, I had to think of a way to divert your attention from my piercing, as it's essential that you don't wriggle too much. We will be making quite large holes and there's not so much flesh to push through."
"This should help a bit", I noted, putting two ropes above and below her breasts and tying them together behind her backrest to pin her upper body to the point.
"To provide enough distraction, I needed this special chair. You might have wondered, why your legs are spread wide apart, though I'm going to pierce your nipples..."
Mentioning, "Did you know, that electricity is conducted best by liquids?" I presented a metal wand, consisting of ten intersecting metal balls with roughly an inch and a half of diameter. In total, it was 10 inches long. An electric cable was hanging from the end of the piece.
Lubing the ball-dildo heavily, I grinned at her irritated expression taking my thumb and pointing finger to spread her already exposed butt-cheeks even more and putting the first ball of the dildo softly against her sphincter.
