Please read the above story. If you are interested, we are looking for a female superheroine that could make up a second lover for my Superman character. As noted, this story is extreme. Check ClaireT's O-O's thoroughly to understand the sexual things that might happen in this story and which not.
Ideally, this character would be... Supergirl, Starfire, Huntress, Zatanna or any of the younger or less prominent superheroines. Wonder Woman for example, wouldn't work really in this story's context. Villains are also a possibility. No limits on who, from Maxima to Catwoman.
The character we are looking for will also be submissive to Superman, but is allowed to be dominant over the forced Batgirl. We can work it in that either your character is a willing participant, or forced like Barbara.
Pm me if interested.
