Jeff saw a pre-made character described as the "OK" Maid. Victorian, wore glasses, short dark brown hair, very to the point, and was enabled with chronivac powers to do anything asked of her... with a few issues if you ask them to do something "Too complicated" Which was fine all things considered. Jeff summoned the "Ok" Maid and there she was. A bit stiff but a beauty in a sense.
"Hello?" Jeff asked
"Greetings master Jeff, I'm your servant how can I help you?" The "OK" Maid asked
"Ummm... could you make your boobs bigger?" Jeff was looking the Maid over and while her breasts weren't small...
"Of course" The maid responded as her chest started to swell till her clothes were having a hard time constraining them.
"Wow those are large..." Jeff said staring at them "Bigger?" he asked and got closer as the Maid's buttons broke revealing massive mammaries being just held behind a lacy black bra. "Can I touch them?" Jeff asked
"I exist for your pleasure, do what you wish." It was something simple for Jeff to do as he reached his hands out and grasped the maid's breasts. His hands did envelop and play around with her soft flesh, but... The maid wasn't really emoting much and... Jeff could ask for her to emote more but at this point that felt awkward. Jeff lost track of time and was surprised when the maid said "I hope I've been of use, goodbye" and then 10 minutes had passed and she just vanished. No clothes, no slightly judgmental seeming look, no boobs, just nothing. Jeff could always increase the time limit, put on a different condition for the "Chatbot" to disappear... Still...
Jeff summoned three maids under the time limit. Jeff pointed to one and said "regress to 15 and rub my feet" and he sat down as he saw the maid do the order, then "You massage my shoulders... and you get a much curvier figure and start cleaning my room." Jeff smiled even though the massage maids needed a bit more guidance on how hard they should massage. "Cleanup maid, bigger boobs please~"
