Tim sighed and signed the paperwork "So I just go in that thing and you do the rest?"
John said "You go in that thing, strip naked and put your clothes in the compartment. Then I'll do the rest." Tim resigned himself to going into the chamber. One short sequence later Tim found himself in the same green test room as Carla.
Carla said "Hi, Tim. Nice birthday suit."
Tim covered himself up, but before he could he was put in a hospital gown like Carla's. Tim glared and said "Ok was that on purpose?"
John's voice reverberated inside "I mean we didn't have your clothes information to import inside. Now then while we are doing everything I have a copy of your current selves. Is there anything you two would like to test out? Keep in mind I have more testing coming up in about two days. You'd be free to change back if you so wish."
Carla said "Ooo! Can you make my boobs bigger!?!" John made a few keystrokes and the two virtual people looked at Carla's breasts enlarge to E-cups.
John asked "big enough?"
Carla nodded and said "These are more than enough. Do they make you wish your were straight Tim?"
Tim sighed and said "No, not particularly..."
John thought and said "You know we can actually change that."
Carla asked "Wait, can you actually pray the gay away or something?"
John said "No, but that was one thing I wanted to test around a bit. Something about the sexuality being determined by all sorts of variables... Had someone who knew more about this than me come in and make a program which he believes can change someone's sexuality from straight to gay. Nothing much about bisexuality though... Or I could give you a woman's body to make it easier to attract men. Again this can all be restored to normal if stuff doesn't work out."
Tim said "I suppose this is a unique opportunity, but what would everyone at work say? Could you send a note to my employer?"
John said "Yeah, sure. This isn't some secret experiment or whatever."
Tim thought about what he wanted and said "I'm not sure what I would even want. How about you choose for my Carla. You've got a better idea what you can do here than I can."
Carla grinned and said "Yep, I got an idea what could be fun to do with you. How about..."
