While the raw sexual potential of your newly modified body did indeed fill you with great lust, it was tainted by a growing irritation. Despite having nine heads on your new body on top of countless extra parts, it was immensely frustrating to be unable to operate them individually without extreme concentration. How could you enjoy yourself (yourselves?) if it didn't feel more natural? As odd as the sentiment was for someone with a triple-conjoined body, the memory of how well your girlfriend could handle four bodies independently was a reminder of what the machine was capable of.

It felt closer to you somehow in an ethereal sense. As the doors opened, you stepped out of both pods at once. While the movements were still in sync, you felt like you didn't have to concentrate nearly as hard to move the foreign configuration of your transformed female body.
This was an improvement, but you still felt like it could be better. Recalling that the terminal stated restrictions for copy upgrades could be lifted sooner by having sex, you looked over at your newest body with both your original body and the unaltered girlfriend body, and decided...
