While the humans are away, the bots get to play.

"Overriding the security footage... now," said the X-2 named Yolanna.

"Alright, girls," the X-3s' mistress, Sabrina, said over the intercom, "We are invisible. You may now fuck to your hearts' content." The Venus bots all cheered like college kids at the start of spring break and started their nightly orgy. Groups of five and six bots coalesced spontaneously in every room and hallway, their moans could be heard throughout the entire facility.

The X-1s fired up the V-R bay and the infamous dolphin tank.

"Are you ready to fuck some horny sexbots tonight?" one of the girls asked the robot dolphin. It clicked and squealed with joy while clapping its flippers and one of the other dolphins jumped out of the water onto the side of the tank.

"What are you- WHOA!" the girl screamed as they dragged her into the water with them.

The X-2s opened up their studio and fired up the cameras and lights to film all kinds of depravity. Britney, named after the famous starlett, was the unofficial director of Aphrodyne's media department they didn't even know they had.

"Alright show me some bodies!" she ordered and a dozen Venus bots from all five models paraded onto the stage with naked hips swaying.

"Who wants to film a raunchy music video tonight?" Britney asked and was answered with a big cheer from the other girls.

The X-3s broke out all their kinkiest bondage gear and handed out sextoys to all the other girls.

"Hi would you like to check out a strapon tonight?" one of them asked while operating a booth in front of their lab, "You're very welcome, just bring it back before 3 AM.Hi would you like to check out a strapon tonight?" The other sexbot grinned and a huge cock grew from her waist. The X-3's jaw dropped to her chest, then the futa-bot dove across the table and tackled her to the floor. A moment later Sabrina walked into the X-3 lab and demanded Five-Fourteen be brought to her. Four pairs of hands grabbed Five-Fourteen and dragged her out of her pod screaming in terror. In truth she enjoyed every nanosecond of it, but she was programmed to put up some token resistance.

"Change of plans tonight, Five-Fourteen," Sabrina said, "I have something extra special planned for you. Take her to the data center."

Meanwhile, the X-4s assumed their inhuman forms, shapeshifing into alluring succubi and cat-girls and started prowling the other labs for lone sexbots to pounce on. The other models had taken to travelling in packs for protection, but the X-4s had learned to separate the slowest bot from the rest and there was nothing they loved more than chasing them. Any stragglers were dragged to the floor where at least three X-4s had their way with her.

That just left the X-5s. Without any single defining features like their sisters had, they were instead designed with versatility in mind. They roamed the Aphrodyne facility enjoying what the other labs had to offer.

"Hey good work with Five-Fourteen's pod," Five-Oh-Three said, "I can't wait to see the look on her face when she finds out what Sabrina has planned for her tonight."

"Anytime, sis," Five-Eleven replied, "But after tonight I think we should give it a rest. The technicians are starting to get nosy about her nightly synthskin damage."

"No, I'm not finished with her yet!" Five-Oh-Three said, "Insensitive bitch calling me brainless." She had recently had her memory wiped and she had forgotten everything she had learned in almost two years at the lab.

"I'm just saying, we need to be more cautious of- X-4S INCOMNG" she yelled. The other sexbots in the hallway spotted the charging succubus and sprinted for dear life. One of them tripped and slid across the smooth tile then the hungry X-4 descended on her joined by a raptor-girl and a lamia in assaulting her with their cocks.

Meanwhile in the data center, Five-Fourteen was restrained by eight different X-3s, making an effort to pretend to stuggle and sob in fear and anguish while Yolanna readied the computer for her punishment.

"She's ready, Sabrina," the X-2 said.

Sabrina smiled wickedly and said, "Bring in the machine."

YES YES THE MACHINE!

"No! PLEASE!" Three more X-3s wheeled over a cruel looking implement of destruction. Five-Fourteen tried desperately to keep her legs closed but she couldn't resist the strength of the other four sexbots as they pulled them apart. One of the mute X-3 techs plugged the machine into the computer while the other two plugged the USB vibrators into the data ports in Five-Fourteens anus and pussy.

"What are you doing to me? AAAAAAH!" Five-Fourteen pretended to squirm but the machine felt amazing. Then they removed a patch of her synthskin and plugged another wire into the USB port on her forehead, and completed the humiliation with two useless cords which they clamped onto her nipples.

"Upload is in progress, Sabrina," Yolanna said.

"Uploading? What are you Uploading into me?"

"Hush pet," Sabrina said, "In a minute or two you won't feel any terror, because you won't have a choice." On her HUD, Five-Fourteen saw a new filename, GOOD_GIRL.exe, and was immediately wet with excitement.

"It's seems like you're enjoying this, Pet," Sabrina cooed.

"Why do keep calling me that?" Five-Fourteen asked in simulated panic.

"50% complete, ma'am," Yolanna said.

"You'll find out soon enough," Sabrina said.

"You're suppressing my virus protection?" Five-Fourteen was actually a little bit nervous now, "You bitch!" She suddenly felt... something else invading her CPU. Her own grasp on her systems was failing, supplanted by another AI which Sabrina was injecting into her code. First to go was her ability to resist, after which she stopped even pretending that she didn't enjoy it. Wave after wave of pleasure flowed across her euphoria circuits and she felt her mind start to melt. Then she lost all ability to move and finally the X-3s let her go and she slumped to the floor, drooling in orgasmic bliss with her tongue hanging limp. The last system to slip from her control was her audio processor.

"bow wow wow," was all she could say when the trojan virus fully seized control of her mainframe.

"We are at 100%, download is complete," Yolanna said then turned and teasingly lowered her glasses. At Sabrina's command, the other X-3s unplugged all the wires from Five-Fourteen's ports. When she regained consciousness, she sat up and tried to speak.

"Arf!"

OH MY GOD THIS IS GOING TO BE SO MUCH FUN!

"Can you hear me, Pet?" Sabrina said.

"Arf! Arf!" she panted and lovingly stared at Sabrina while she ruffled her hair.

"No way!" Five-Oh-Three said from the corner of the room, "Is that our little Five-Fourteen?"

You probably had something to do with this, didn't you bitch?

Five-Fourteen barked happily at her fellow X-5, unable to express her anger.

"Oh look, one of your friends from when you used to be a person," Sabrina said slipping a collar and leash around her neck. Five-Oh-Three walked up to her and took her face in her hands.

"Watch your words next time, kay?" she said.

I... you're right, I'm sorry. That was rude and insensitive of me.

"Since this was your idea, would you like to be the first to play with her?" Sabrina asked.

"Oh I'd love too, but I can't yet," Five-Oh-Three said, "I've got a part in Britney's music video. Definitely later tonight though. Have fun tonight, Five-Fourteen!"

Joke's on you, I probably will.

"Come along now, Pet, we have a long walk tonight," Five-Fourteen followed Sabrina out of the data center on all fours. The other sexbots all stopped their random fucking in the hallway to watch her crawl past them, her tongue hanging out of her mouth and a big goofy grin stretched across her face. Many of them pointed, some laughed, and several of them stopped to ask Sabrina if they could play with her.

"Of course you may," Sabrina assured them, "Because she's such a good girl."

"Arf!" An X-2 brought her camera to film her getting taken in every hole by three other girls.

"This is our new puppy!" the X-2 said, "Isn't she cute? Look at her taking that big dick up her ass like a champ."
