Ashley is Skeptical

"You don't actually believe that that works, do you?" Ashley asks Casey. "I mean, I've tried to seduce straight girls before, a lot of times, but it never works. They just act like they're either not interested or totally disgusted."

"Well, maybe you're doing it wrong," Casey says, crossing her arms, her apparent do-no-wrong attitude still fully intact.

Maybe it is time that you put this bitch in her place.

"Whatever," Ashley says. She turns towards you again, then back to Casey. "All that stuff you said won't do anything to him anyway," she says, gesturing in your direction. "He's a guy. He... will even get off on it." Her face clearly betrays what she thinks of the idea of you fapping while she and Casey are having a good time.

You then whisper "I wish Ashley and Casey will want me to join them in sex."

You don't really put much thought into that wish, just want to have sex with these two beautiful girls.

Only when the magic begins to tingle, you realize that maybe it might not be granted the way you expect. After all, the wish could turn Ashley and Casey into bisexuals, the way you intended. Or it could change YOU into a lesbian girl instead, the type of girl these two are interested in.
