Super story
This article discusses famous characters under copyright, but is commentary on how particular large corporations are harming the public good through their biased presentations (and they have every right to express their biases) and how I think they could dramatically improve their storytelling.
Others have pointed out that as depicted in canon, Superman cant safely have sex with ordinary humans, because his super sperm would fly all over the globe and attempt to impregnate all human women (and possibly all species), with a result of impregnating all women, destroying the fertility of all women, or possibly even kill all women.
It has also been pointed out that Supergirl couldnt safely have sex with ordinary men, as the involuntary contractions during orgasm would crush an ordinary mans penis and maybe kill him.
It is possible that Wonder Woman might have the same problem as Supergirl.
Further, some suspect that Wonder Woman might be lesbian or bi.
So, a sissy maid would be a pleasant solution for both Supergirl and Wonder Woman, although not helping Superman.
In comic book canon, Supergirl was trained by Wonder Woman.
So, imagine Supergirl and Wonder Woman are a couple and a sissy maid is chosen to spice up their sex life. The sissy maid would become a target for super villains whenever the super heroine couple is elsewhere from their headquarters. And maybe even while they were home.
So, I suggest throwing in a super powered inflatable sex doll that provides the sissy maid with pleasure and has the power to save the sissy maid from even the strongest super villain.
My claim is that is a much more interesting story.
