If Cy's the trans one, I think his parents would be mostly OK with it because they both wanted a son, so in a way it's like they're getting their wish. For Lynn/Eden, transfem or transmasc, I think their parents would chalk it up to a trauma response from The Incident and let it slide because they love their only child so much, even if they're not necessarily comfortable with transness.

No nullification planned, although it does look pretty bare. While her new clit isn't prominent at all (it blends in with her minimal labia) it's enough for her to cum!

Probably just as long as with canon Lynn, if not a bit faster!
