"I'm setup differently? You make me sound like a computer program." As you spoke with your male body, your naked female body struggled onto her (your) feet.
"Sorry. I didn't mean it that way. Uh... When I was setting up the cloning for you earlier, I set it so the cloned body would be temporary. It said that it would generate with a brain but the brain would be dormant and wouldn't be capable of independent thought." Your girlfriend sitting across the table explained. Her pantsless body that had just woken up reached out for your female body. She pulled you down onto her lap, put her arms around your waist and held you close.
"Okay, so that's why I don't have 2 brains. Also, temporary? For how long?" your female body asked across the table. Your male body stared at your naked body sitting in the lap of your pantsless girlfriend. 2 identical girls sitting casually next to you... and you controlled one of them. The temptation was strong, but the desire to know what had been done to you was stronger.
"I set it for 24 hours. You get to have your own personal copy of me until around this time tomorrow. I'm sure that's been a fantasy of yours."
A smile crossed both of your mouths briefly. One that your girlfriend definitely saw. In an attempt to distract your girlfriend from her successful discovery of one of your fantasies, you spoke again with your female body, "But what happens when the time is up? Do I have to come back to the tube? Or like... melt or something?"
Your girlfriend shrugged. "Dunno. Haven't tried it before. I hope it's -" she was interrupted mid-sentence by a sequence of loud beeps coming from all around the room. The girl sitting across the table from you reached into her pants and pulled out her phone. A swipe of the finger later and the beeping subsided slightly in volume. "Oh dammit, it must have duplicated my phone. Help me find all of them."
You and she both stood up and searched around the room. This time, moving with 2 perspectives at once didn't give you any trouble, and you were able to find 1 phone in the pants she had stripped off during sex earlier. A second phone turned up in one of the tubes, along with a spare set of the clothes she had worn to school today. She managed to find the other 2 phones, and soon the room was quiet again.
"That was my alarm. I really need to go." She frowned and her naked bodies started to get dressed, leaving the extra set of clothing in the tube. Her two dressed bodies approached your bodies and kissed both of you at the same time, preventing you from speaking. As she kissed you, her other bodies spoke, "This was amazing. I love you. My phone number's on the table. Text me tonight."
She broke off the kisses and all 4 of her started to leave.
"Wait! Why don't you stay? At least 1 of you..." You called out to her.
Her last body paused and looked back. "I wish I could, but... I can't. Not yet."
"But! You have 4-" "-It doesn't work like that! Read the terminal. I gotta go!" She looked genuinely sorry and saddened for having to leave, but turned and jogged out.
"What about me?" You called after her with your female body.
"She's yours! Do whatever you want. Maybe... go fuck yourself?" Her last words left you standing alone with yourself in the chamber. That was the second time she had brought up having sex between your male and female bodies. It was an appealing thought, but perhaps one best explored in a private location. But this chamber also had the devices that had changed both you and her, including a terminal that might have some answers about why she had to run.
