I have watched a lot of porn featuring Superheroes being sexually humiliated and or dominated by villains. I have a tiny penis and an sph fetish so I love the ones where the hero has a small penis and is humiliated and dominated by a larger dicked foe. I also love lesbian versions as well (faves feature Lara Croft being fucked by Harley Quin or Batgirl being tied down and humiliatingly molested by two female villains) I came across one where Robin is captured by a couple of female villains and they give him some super sph by humiliating him because he has a tiny cock. There is one where superman is subdued and wanked for his semen by a villain ( who happens to have a much bigger cock as well) There is one where Batman and Robin are forced to have gay sex. There are numerous ones where various female villains capture male or female superheroes and play with them or male villains do the same.
Things have become a lot more complex since Lynda Carter put on those sexy red boots with her golden lasso as Wonder Woman.
You have to say a lot of comic book, film and tv superheroes and heroines and villains are quite pornographic.
