headcanon is that Souji's cock is average in length, but thicker than average. he's very unlikely to be circumcised. like most teenaged boys he normally wouldn't shave much in that region, but once he realizes other people are going to see him naked, he'll trim a bit for neatness sake. And of course. The grey hair is natural, not dye.
that said she's actually pretty indistinguishable from a normal human but probably seriously don't fist, there still be steel under there. no hair down below because her appearance is entirely based on her self-image and why would a robot need hair downstairs
Megumi is well-groomed and surprisingly has no scars or abrasions despite having gotten into very brutal fights and combat. She's also very fit and toned, her tail and ears are where she's got most fur and she's heavier in the chest, moreso after having a baby- but does massage herself into shape as well there.
She also has small sharp canines and claws she can extend- so some partners might end up scratched But she's a healer too so that's always taken care of.
Makoto (Kino) doesn't tire out. It's not really a sexy headcanon, but since her powers are mostly physical and seem to carry over into her human form, it'd take a whole lot to sexually exhaust her.
couple of nightsnight she was here? lmaowhy would a robot need hair downstairs
