A Loli's ENF Adventure/CYOA/Luminia/Civilized Race/Wood Elf
Wood Elves: A race with very close ties to humans both physiologically and socially, wood elves make their homes out in the forests they get their names from, and you'd be hard pressed to find one in a human settlement larger than a village. Indeed, many wood elves tend to be loners, sharing their forest home with only a few other family at most and living far away from heavily developed areas. Wood Elves are fair skinned and most commonly have dark brown hair coupled with green eyes, but blondes and redheads are not uncommon.
Wood Elves are known for having much more lithe and slender builds than humans, with women in particular never having more that a B-cup breast size unless they have some human ancestry. Instead, the most prominent secondary sexual-characteristic are their buttocks, which tend to be round and full and are often emphasized by elven clothing with formfitting trousers and shirts that split at the waist to leave them uncovered.
Because wood elves are long lived, their bodies undergo physical development at slower rates. For example, whereas a human girl would be on the cusp of puberty for less than a year, for a wood elf girl that period will last many years before actually beginning puberty, with instances of this period lasting a whole decade being not unheard of. However, their mental development is not hindered quite as much, resulting in prepubescent wood elf children appearing very clever and intelligent for their age.
One last note of wood elven children is that, thanks to their race having a natural connection to the world around them, they tend to be rather free spirits. Having no fear of wild beasts, getting lost, or starving, wood elf children often go on their own little adventures for days at a time, so long as they inform their parents first, of course.
Now, let's move onto the finer details of this girl next. To keep it simple given the differences in growth compared to humans, is this girl more underdeveloped, developed, or part way?
