Given the amount of sexy, fuckable women that made up Kronii's coworkers at Hololive, thoughts of threesomes have of course crossed Anon's mind
But given Kronii's clinginess towards him, he wasn't sure if even suggesting it would be a good idea, let alone doing it and having to deal with jealous bitchy Warden of Time afterwards
So it knocked the wind out of him when Kronii brought Roboco to their home and pretty much asked him to fuck the robot for her
"It's simple, Anon. Roboco will satisfy you while I watch and direct you two and all you have to do is enjoy it."
Anon gaze slid from stoic-looking Kronii over to the smaller, smug robogirl next to her
By god, whoever designed her should get award of Ultimate Sex
The combination of lack of skin around the inner parts of her legs on top of her wearing no pants created an illusion of a constant exhibitionist, especially in contrasts to her regular top
She remained quiet, but was clearly very in favor of this arrangement
"Ok, b-but what's the catch? No way are you just gonna let me fuck one of yo-"
Anon was suddenly silenced by Roboco, who stepped closer and pushed her lips against his, her tongue extending forward into his mouth
It was a strange experience, enough so that Anon completely forgot what he was gonna complain about
Both her lips and tongue felt soft, with her muscle having a bit of sliminess to it, probably some sort of stored liquid being released over it
Anon was somewhat brought back into reality when he felt Kronii's tits press into his back
"Don't worry, there is no catch. I will be satisfied as long as you do a good job following my instructions and blowing her fuses out."
Her hands started to caress his chest, while Roboco's started out more daringly, with one hand groping his bulging crotch
Anon could no longer hold back and started to moan into Roboco's mouth, which seemed to get progressively warmer and warmer, together with her lips and tongue
Her taste also grew sweeter the more he tasted her
This was something completely new and alien to him, it was nothing like kissing normal human, like kissing Kronii...
Then they started to undress him, Kronii getting rid of the shirt and Roboco making short work of his pants and underwear
Before he could complain, he was pushed onto the couch, now butt naked
Then he got to watch the girls undress too, Roboco making a quick work of her top and sitting on him, her cold, rubbery-feeling ass
As Anon watched Kronii toss her shirt away, exposing those lovely fat mammaries contained only by a lacy bra and working on her pants, his chin was suddenly grabbed
Roboco turned his head to face her, as smug as ever
"Now now, you should be paying attention here~"
Roboco kisses him again, the warmth of her mouth melting any resistance he might have planned to put forward
Kronii joined them shortly after, laying down next to Anon in only her underwear
Her panties were already soaked and when she slid her hand into them, Kronii couldn't help but wince when she touched her sensitive pussy
This was already firing her up more than she expected and they didn't even get started properly
"Ok, now get down and suck his cock, Roboco..."
"You got it~"
Roboco quickly got up and moved Anon's legs apart, kneeling between them and bringing her head to his fat cock
Only then did Anon's lust-clouded brain process what was awaiting him once Roboco started her blowjob, but it was too late to properly brace himself when the steaming pleasure furnace that was previously dominating his mouth and tongue trapped his cockhead in it's embrace
Her tongue started to swirl around the leaking tip, Anon's mind going blank for a second as the wetness and warmth made him feel like his cock was melting
His hands slid into Roboco's short, brown-n-red hair, gripping for his dear life and trying to move her, but she won't budge, her mechanical body easily resisting the attempts to move her
Kronii meanwhile applies some of her powers to his cock, stopping him from busting in matter of seconds
"K-Kronii, please..."
Kronii places a finger over his lips, silencing his pleas
"Remember, my idea, my rules. You will cum when I want and not a second earlier"
And so his cock was locked in whirlwind of stimulation, pushed to the absolute breaking point just with the Roboco's mouth
She was relentless, always sliding up slowly to his tip, only to plunge down his length, complete lack of gag reflex making it easy to torture him with her custom made throat
Kronii pressed her body to Anon, was now squirming and moaning under Roboco's relentless assault
"Look at her go. If it wasn't for me, she would have drained you to the last drop by now. What a powerful sextoy you are, Roboco."
Roboco winks at her, before turning on the suction module in her throat and sending Anon into another thrashing fit
His toes curled as far as they could go, with his fingers sunk into the soft surface of the sofa
Seeing him like this, Kronii couldn't help but get even hornier, sound of her wetness as she fingered herself added to the mechanical humming from Roboco and desperate moans and cries for release from Anon
Kronii only barely managed to stop herself from orgasming just from that
"Ok, stop. Now, darling, facefuck that little robobitch..."
Roboco paused, obediently waiting as Anon processed the new order
Took him a moment to get a grip of himself, body weakened by the nerve-melting blowjob
Once Anon calmed down a little, he started to move his hips forward, the feeling of Roboco's perfect, tight throat sending shivers down his spine even if he was the one in control now
As he started to pick up the pace, Roboco's stared right back at him, artificial drool running down her chin as it was fucked out of her orifice
Kronii let Anon hump Roboco's face like crazy for a while, until her own lust started to get unbearable
Cleaning off her hand with her tongue, Kronii decided to advance it closer to the finale
"Roboco, get on the couch, legs apart."
"Roger roger~"
Roboco assumed the position and thinking ahead, already made the plate covering her crotch slide inside of her, revealing her robotic toypussy, already leaking a lot of lube as she grabbed her robotic legs and held them as wide apart as possible
"Come on big boy, let's give Kronii a good show"
Anon didn't even wait for an order, moving over Roboco and guiding his cock to her wet entrance
Kronii was too horny to care about it, standing up and again assuming position behind him, tits pressed into his back, but not before discarding her underwear
Anon could feel her rock hard nipples and hot, wet pussy against his skin as he slid inside of Roboco's pussy
Both of them arched their backs, Anon's mind blanking against as Roboco's cunt was even deadlier than her throat
Roboco went with "Sensitive" mode, putting on a perfect show as the pleasure was translated from sensors into her processor
Kronii was humping against Anon, enjoying the show in front of her as the two melted into each other, Anon's unrestrained thrusting forcing his cock all the way to the back of Roboco's pussy module
Only noises of loud slapping and moaning could be heard, no one spoke a words as they drowned in ecstasy together
Kronii's powers started slipping, letting Anon get closer and closer to his orgasm, each slip up followed by a loud grunt and increase in tempo of his already wild thrusts
Roboco meanwhile just laid there, folded on half and screaming, her voice modulator sometime struggling keeping up with the desired volume Roboco tried to produce
Being sandwiched between two incredibly sexy Vtubers while being in relationship with in one of them and being balls deep the other, Anon didn't last a second longer than Kronii did, her orgasm immediately resulting in his own hitting as well
As the couple came on top of her, Roboco's systems started to go haywire as well, sending her AI processor brain into orgasmic bliss, almost causing her to shut down
Once the last scream of bliss died out, the room became completely silent, aside from two pairs of heavy panting
Anon pulled out of Roboco, causing a large amount of his cum to leak out, and collapsed onto the sofa again
Kronii, while also suffering from post-orgasmic weakness in her muscles, threw herself at him and started to clean up his cock, causing him to yelp and almost cry as her throat hugged his sensitive, partially flaccid shaft
"Just so that you don't forget who you belong to..."
Kronii whispered into his ear as she pulled herself up, grabbing his head and letting it rest on her fat tits
Upon rebooting, Roboco snuggled to him as well, with not protests from the either, soft and warm skin contrasting with the cold metal and synth-skin on the other side of his body
All three rested, until the thirst got too much and they had to get up for some refreshment
It was clear to all three that this was not gonna be a one of thing, but what Anon didn't know was that Kronii already had plans to get as many girls on Hololive as possible to jump his bones for her personal pleasure.
