Mirrors.

"You catch the game the other night?"

"Yes! That last play was amazing wasn't it? My wife was screaming in my ear during the last five minutes."

"Oh god, mine too. We had Diane and Matt over and-"

Something shattered in the hallway when the two engineers ran to investigate, they found one of the sexbots lying in a pile of broken glass. Jagged pieces were sticking out of her arms but she seemed more annoyed than in pain as she pulled one of the bigger pieces out.

"Watch your step," one engineer told the other who weaved through the maze of glass shards then looked at the gynoid's arm band to get her serial number.

"514, what are you doing?"

"Hi, Cameron," she said as he pulled her to her feet.

"I didn't know there was a wall there," she said sheepishly.

"You didn't know there was a wall there?" Cameron said, "How did you not see a wall?"

"Well I saw a woman heading towards me," the gynoid, "She was hot, so we ran towards each other hoping to get nasty, and, well, this happened."

"There is nobody else here, 514," the other engineer, Daniel, said.

"Another woman..." Cameron said, "Oh. OH!" The realization came to him and he carefully picked up one of the panes of glass.

"This is a mirror," he said, "That is your reflection. You cannot have sex with it." The sexbot leaned in closer to see.

"Oh, sorry," she said, "I just didn't recognize myself." More people came running after hearing the crash.

"What happened?" one woman asked.

"514 ran into a mirror," Cameron said, "Careful there's glass everywhere, we need to clean this hallway." When someone had taken the damaged sexbot to repair ward, Daniel and Cameron returned to their office.

"Stupid bimbos," Daniel said.

"There not stupid," Cameron said, "It's just, how do you teach something that can shapeshift to recognize its reflection?" They heard another crash, looked at each other, then ducked their heads out of the office to see another robot at the far end of the hallway lying in yet another pile of broken glass.

"We have work to do," Daniel said. Cameron nodded and they ducked back inside the office.

"'Request for requisition of a Venus unit for experimental testing of visual recognition and self awareness,'" Linda, the director of Quality Assurance read, "I hope the two of you aren't just asking for an office sex-****."

"Uh, no," Cameron explained, "We are concerned with the Venus line's inability to recognize themselves in a mirror."

"But we're not sure how long this will take," Daniel said, "Or how in depth it might get. We think it would be easier to focus on one of them at a time until we know it works."

"So it would be easier to have one in our own lab so we don't lose progress." Cameron explained.

"Uh huh," Linda said, "so then you have absolutely zero plans to have threesomes with it in your office."

"..."

"..."

"Maybe just a little bit," Daniel said.

"Well, at least you're being honest," Linda said, "Don't think I don't know how everyone uses the robots around here. I expect regular updates though, so don't think you can slack off just because you working with a programmed nymphomaniac."

"Yes ma'am," the engineers said.

"I've actually been trying to get approval to tackle this for months now," Linda said, "Corporate seems to think it's not that important, but we'll see if they still think that when they start breaking mirrors in their owners' homes. I'm sure they would just love the flood of warranty requests."

She signed their requisition form and said, "There you're approved. Let's see... there's an X-4 unit that's unassigned. I'll direct it to your lab this afternoon."

"Thank you ma'am," Daniel and Cameron said, "We'll make good progress... in spite of... well you know."

When they had left Linda scooted her chair back and looked under the desk.

"Did I say you could stop just because I had visitors?" she asked.

The sexbot poked its head out and said, "No, mistress."

"Then keep licking," Linda ordered and pushed the robot's head between her legs.

"So what do you think the main problem is?" Daniel asked, "Is it that they don't remember what they look like or what a mirror looks like?"

"I'd rather not have any preconceived notions going into this," Cameron said, "But if I had to guess, I'd say it's the former."

"So then how do they know what kind of woman they are morphing into, but then they can't recognize that same woman's reflection?" Daniel asked.

"We won't know until we take a look at their code," Cameron said.

"Excuse me," the engineers turned to see one of the sexbots in a blonde pony-tail walk into the lab and she was clearly going for the whole college intern look with a dark skirt and a crisp, white blouse that fit her like a glove. "Hi, I'm X-427. I was ordered to report to Cameron and Daniel for experimental testing."

"I'm Cameron and that's Daniel, so you've come to the right place," he said. Daniel waved and sync'd the robot with his tablet.

"What will I be working on?" the robot asked as she looked around.

"We're trying to figure out why you robots don't recognize your reflections," Cameron said, "It's too late to start tests today, so we'll start that tomorrow morning and work on moving your charging pod in here. So for tonight you may stay in the X-4 lab."

Daniel pulled up the sexbot's body options and liked what he saw. She was an X-4 which meant she had other body parts that didn't come standard for humans, and he saw that she could morph into a succubus, a cat girl, an angel, and an alien with three boobs among others. This was actually a very large selection for an X-4, but that was only because they were still in development. The final production model wouldn't have so many options.

"Well if we're not starting today," 427 said, "Then how do you want me?"
