Elpeo Ple and Ple Two were even some of the most iconic early characters in this regard. Ha. Ha. Anyways, she's ten, so fair warning that this is default with her.

Ple Two is put to use, possibly by all the soldiers she's serving alongside relieving their sexual frustration on an obedient girl. Could be solo or gangbang, and could involve restraints, either scheduled times or just casually pulling her into a closet.

Ple Two somehow survives her role as a soldier, but ends up with only one avenue to survive as a dangerous child soldier with no war to fight - selling her body.

Or she's outlived her usefulness; or her very life is sold, with or without her knowledge. Long and drawn out, or smashed onto the end of a scene, any method and level of detail should be fine.

Sex in orbit! She spends a lot of time aboard space craft without any kind of artificial gravity so that's pretty normal.

...well, she's pretty developed for her age, so it could happen, right?

A lot of this is more suited to older partners, but other too-young, precocious partners are very welcome too.
