"...We turn you into a cute girl, we could do a sleepover or something!" Carla said, "I could even let you borrow some of my clothes."
Tim sighed and said "Well that's what I get for giving you the choice... John, you made Carla's body can you give me her old measurements for my temporary form?"
John's voice came out and said "That should be simple... First I'll just copy down all your body's data for later retrieval, and potential medical purposes... Now then time to replace your organs with female organs and-" Tim squirmed for a second as his gonads were replaced with ovaries, his heart and other vital organs were replaced with the replicas of another woman.
Tim sighed and said "That felt weird..." and then crossed his chest and then said "Huh, Wha they feel... different..."
John said "Yeah, you look mostly the same however essentially you are a woman in Tim's form. Wait a month and you should get a period out of the tip of your dick... That could be an interesting experiment but not for now we're making you a woman. All that organ shifting means that while your nipples look like your ordinary ones and are at the same size... They are female nipples."
Tim blushed a bit and said "Well can you make me look like a woman now that I'm basically one?" and then his chest surged forward. Time held his now rather size-able chest and said "I don't think Carla had breasts this big when she came here!"
John chuckled and said "Just having a little fun." as he was essentially erasing Tim's dick, widening her hips, etc. Till her body from the neck down was a skin tone shifted version of what Carla currently was... Minus Carla's inflated breasts. John said "Now I just gotta edit your vocal chords and face a bit... By the way do you prefer your hair long or shorter?"
Tim said "May as well go-" then noticed that her voice was now really squeaky.
John said "Alright maybe that was a little too high pitch, try it now."
Tim coughed and said "Do Re Mi... Yeah that sounds... better... While we're trying something different may as well give me a long hair cut..."
A few more edits later and Tim was now a rather cute looking girl, "Ok... That should be good." a hand mirror materialized in Tim's hand as John spoke "Alright, look good to you?"
Tim looked at herself and said "Yeah... I look... good I think?"
A few zaps and clothes changes later Carla and Timantha were in the real world, and got themselves back to Carla's apartment. Carla was in a robe and have given Timantha one of her pajamas.
Timantha sighed and said "So you're going to return a lot of these back and get something sized better for your now larger chest?"
Carla nodded and said "Yeah, We should also get you some clothes for your own work. But first let's enjoy our night together and get you used to the female body. You still gay?" As she started tickling Timantha. Carla had noticed her new body was ticklish, and considering their bodies were based on the same person they were able to have a fun time tickling each other.
