Where can i find the story ?
in the inflatality group ?
To stay in the subject , i think before nanobots and genetic manipulations will be available , we will see more "mecanic" system like implants , ok nanobot will do their job in some day or hour , but in case of genetic manipulation you will have to wait years , hopping you still have to grow ..
I hope for implants with micropump in , or with an external valve , who , with progress will be invisible , so women will have the remote control in the pocket , and sometime let their boyfriend play with it

and why not implants for more part of the body , lips (the other too ), legs , nipples etc etc still bith remote control (imagine the remote , this will be a "body control center " )
The wheel of your car is too high ? hmmm, press the "inflate butt" button , and yeah !!, you see the road
