Natasha has now been constantly stimulated right to the brink of a mind-blowing orgasm before being tickled all the way down again and again for almost four hours. During this time, she has been edged and denied well over fifty times, and it has all led up to the final round of the tickle game she had subjected herself to playing. Emma, the merciless AI putting her through this torment, has promised that if Nat forfeits the last round, she will give the latter the earth-shattering climax that has been so cruelly kept from her for so long. But of course, this doesn't mean Nat won't be tickled out of her mind for a little longer.
***
Nat was barely listening to a word Emma was saying. While there was nothing touching her skin, she had been suffering the last ticklish torment for so long, that her pussy was still twitching as she could feel phantom sensations of soft brushes and stiff feathers flicking and stroking all over her nipples and clit, causing her to remain in a daze, occasionally giggling and moaning.
"Wow, I've really done a number on you, huh? And look at how wet you've been this whole time."
Emma was right, Nat could have bathed in the amount of fluid that had secreted out of her pussy due to her constant state of arousal for over three hours. There was still more dripping out as Nat continued to imagine her clit being attacked from every angle by feathers of every imaginable type. Slowly, she regained her strength and noticed that the sensations had in fact stopped, and Emma was talking to her about the next round.
"This is the final one now, Natasha. You're almost there. 250 minutes. Remember our deal, I want to see you forfeit this round within the first minute. Otherwise... Well you already know what I'm capable of. Removing restraints now."
Her wrists and ankles were removed from their cuffs as Nat lay there exhausted. Her arms were so tired from pulling on her restraints so much in the last round, that she could barely move them anyway. Nat's blindfold was also finally removed and her eyes took a while to get used to the light. Once she could see properly again, she stared at the countdown on the wall ticking down from 250 minutes while wondering why nothing was happening. As soon as she remembered the deal she had made with Emma, Nat gasped and moved her wrist as quickly as possible, resulting in her arms and legs being pinned to the floor again as the tentacles restraining her waist and thighs also returned. She wasn't going to make the same mistake as last time - she was going to do exactly what Emma said.
"That's a good girl, that was the final round! Now you've just got this 250 minute punishment round to get through and this game will be over. I hope you've enjoyed it!"
Nat didn't have enough energy to care about the sarcastic and teasing tone Emma was speaking to her in, all she knew was her need to be taken over the edge of bliss, and now she had finally completed her part of the deal with the machine. She had forfeited the last round just has Emma had instructed her, and now she was ready to claim the orgasm that she had been denied for so, so long.
"I did my part," Nat finally managed to speak. "Now make me cum."
Emma said nothing as Nat heard the familiar sound of holes opening around her, and more tentacles being sent towards her with tools on their tips. She smiled and began to take deep breaths as she prepared herself for the climax of a lifetime. Her pussy was throbbing in need and ready to submit to whatever tools Emma would use on it to throw Nat over the edge of pleasure. But unknown to her, Emma wasn't going to tend to her sex just yet.
Nat's breathing became quicker as she saw the tentacles approaching both of her armpits. On their tips were a wheel rotating at an insanely fast speed. But it was what was on the wheel that both scared and excited Nat. Each of the roughly twenty spokes of the wheels had a feather on it, ready to stroke all over her skin as they slowly approached her pits. She couldn't make out any details of the feathers because they were just a blur in the air, as the wheels span so fast she could feel her hair being slightly blown. It was only when the wheels finally landed deep inside her pits, and she felt every feather scrape across the sensitive skin of the top of her arms, that she realised that those were no ordinary feathers. Nat could feel each of the soft tendrils individually vibrate and wiggle around in her hollows, causing her to once again burst into laughter as her arms were held in place while the wheels firmly kept in contact with her skin. They moved up and down her pits and the surrounding area, sometimes exploring around the tops of her ribs, and at other times tormenting the sides of both of her breasts in unison.
While Nat was cackling away uncontrollably at the feathers on her arms, more holes opened up and what looked like two long rubber sheets came out from the walls on either side of her and wrapped themselves around her sides. Nat couldn't believe how much they felt like human skin. As they firmly gripped her from both sides, she loved the feeling of being held by the warm and soft sheets, so much so that she was not prepared for the insides of the sheets to suddenly start vibrating and kneading her skin. Nat let out a deafening scream as she was ravaged by what felt like dozens of hands mercilessly wriggling all over the smooth skin of her sides and aggressively digging into every inch of them.
The machine paid no regard to Nat's shrieks as it continued its assault and opened up more holes to unleash even more devices on her over-sensitive body. These new tentacles each split into ten mechanical rods at the end. The rods were a few centimetres in length and had a tiny ball at each of their tips. As the spider-like devices descended towards her belly, Nat wearily watched each of the tiny legs wiggle about individually, teasing her as they got closer and closer to her body. She sucked her stomach in to delay the inevitable attack of the spider ticklers for as long as possible, but it hardly made a difference as they got to work and Nat's laughter reached new levels of intensity. There were six spider tentacles in total, and four of them swarmed all over her stomach, poking her soft skin in random patterns as they scurried all around from right under her breasts all the way to her belly button, exploring every patch of skin in between. The balls on the ends of the spider legs started to powerfully vibrate, taking her to new ticklish heights. The pitch of Nat's cries increased even more when the remaining two spider devices chose to land a bit lower, right on the insanely ticklish patch of skin above her pussy. They scampered around excitedly, poking their vibrating balls all over her lower waist, while Nat continued to scream as she lay trapped in the machine, completely at the mercy of the ticklish contraptions wreaking havoc on her body.
Nat's thighs were next to be targeted by yet more diabolical tickling instruments. This time, the tentacles that slithered towards her inner legs had long cylinders at their ends, and Nat could do nothing except brace herself for the new torture as the tentacles continued their advance. The cylinders were covered with feathery tendrils and began to spin rapidly as they dived between Nat's legs, rolling around all the sides of her thighs as she struggled against the straps holding them in place. When moving from one thigh to the other, the bristly cylinders would roll right over her wet pussy, licking her swollen clit as a brief reminder of her immense need to be touched there. But this feeling only lasted a second, as the instant the touch was over, Nat forgot about her denial and simply succumbed to the ticklish sensations all over her body.
It was only when she saw two cups heading straight towards her perky breasts that Nat remembered the deal she had made with Emma. The cups snuggly fit over her tits, and she let out a soft moan as she thought about the orgasm Emma had promised her. After the last three hours of constantly being taken to the brink before being denied release again and again, Nat couldn't wait to experience the most mind-blowing climax she had ever had. As if the tools around her had sensed Nat's building arousal, they intensified their attacks to torment her, while Nat began to wonder how she would even be able to orgasm while being tickled out of her mind like this. How was Emma going to send her over the edge while her senses were being completely overloaded by this unfathomable tickling?
Nat's thoughts were interrupted by the cups over her tits buzzing to life causing her to squeal and try to shake the sensations away unsuccessfully. The insides of the cups were covered with bullet-sized vibrators that were now buzzing randomly. Nat had no way of predicting the patterns they were vibrating in. She would feel a strong buzzing sensation start at the bases of her breasts and quickly rise to their tips, then after repeating this pattern about fifty times over half a minute, the direction would reverse and the vibrations would travel from near her nipples all the way down her tits. Sometimes she would feel the buzzing in a clockwise motion, going around and around her globes a few times a second, and at other times there would be no uniform pattern as every vibrator turned on and off individually, keeping Nat trapped in her fit of ticklish laughter.
