An act of generosity...with a catch

You hear whispering and giggling from the two as you continue licking their boots. You can feel something about to happen, but you dare not even speak your concerns. You catch in the corner of your eye a side table from down the hall move into the room, its legs bending and contorting like an animal's to allow for locomotion and settling next to Aby, allowing her to place her drink upon it.

"I've decided to give a little worm a little relief," Natasha hissed. "Lie on your back. Your wife and I are going to the kitchen to fix her another drink, if you can last that long without bursting we'll consider more pleasures for you."

You do as you are told, releasing your tongue from their boots and taking a prone position on your back. To your surprise, instead of getting up they wrap their booted feet around your cock and start stroking. Nothing makes sense to you, Natasha didn't have to lift a finger to get Aby a drink before and now despite talking about leaving the room, they start this up seemingly with no intention to do so. But inexplicably, they do. You notice the outlines of their feet slide up the shaft of the boots as they step away to walk to the kitchen. However, their boots did not seem to register that they had even left. They continue to pass your cock back and forth between each other without Natasha or Aby's assistance. The boots continue to hold Natasha and Aby's shape all the way up the shaft, but beyond that there was nothing but empty space.

"I see you're enjoying yourself," Natasha chuckles as she stands over you, inexplicably growing taller as black leather knee-high boots began to appear on her feet to replace the ones working you over. "It took so little to awaken these desires in lovely little Aby. She was so **** to let it out for you, Denis. All you had to do was let her in. But instead you came to me, and now here I am doing your work for you." You feel a pressure on her chest as Natasha places the weight of a booted foot on your chest, holding just firm enough to keep you in place but not enough to cause pain beyond your tolerance level. "I think she wants to see how far I can take my powers with the two of you, and I am going to oblige her, because she's worth it. And I might just stick around to teach her, poor thing obviously needs help keeping you in line. Shouldn't be too hard either if boots we're not even wearing get you this hard. We'll be back in a moment, there's plenty more of this where it came from when we return."

Once again Natasha effortlessly steps away, leaving her boots behind as she rejoins Aby in the foyer. You didn't even feel it, but when you try to change position you feel the boot grow heavier to keep you in place.

You seize the opportunity to try and parse some information on the situation playing out in front of you. Your hand slowly climbs the shaft of the boot on your chest, resting at the lip. Despite the leather being filled out as far as it seems naturally possible on the outside, and despite the boot clearly moving itself around your chest in a deliberate effort to avoid becoming too painful, there is absolutely nothing inside to give it motion. Your fingers slip into the inner lining with zero resistance, you palm registers a slightly soft but muscularly firm calf that isn't there at all. Your fingers wrap around the zipper and pull down, no resistance. It's only when you attempt to place your hand into the toe box of the boot that the pairs at your cock respond. A heel drives itself into the junction between your ass and thigh, not hard enough to injure, but enough to tell you that what you just tried to do was forbidden. You pull your hand from the boot, watching as the zipper defies gravity and pull itself back up the shaft with no assistance. Springing back to life, the boot at your chest lifts and uses its toe to nudge your hand away. Instead of returning to its original position, it chooses to rub its pointed toe against your nipple, once again giving you full view of the show at your torso. The boots once worn by Aby were now almost mechanically rubbing your cock between them while Natasha's were underneath kneading the underside of your balls.

You overhear a conversation between Aby and Natasha all the way in the kitchen, cementing their lack of presence in the room. The scene playing out in front of you is no doubt kinda hot in a surreal way but the realization still dawns on you. Your supermodel date is doting on your wife while you're getting a bootjob from empty boots. You got played for a sucker, dude.

A thought dawns on you. How long do you think they'll be staying in the kitchen? And more importantly, what other pleasures does Natasha have in store for you if you can make it through this?
