Flexibility

The buff but hot newly female guards close in distracted by their new female forms as they become more and more horny and have more and more airhead moments.

“Like what did you whores do to us”

“Like if that green one had a nice juicy cock I’d be so horny right now no like wait I’m a guy what am I saying”

Using the distraction Elastigirl stretches her arm out opening the door to the pool hoping for some big swimmers to distract the women and be distracted by the new women.

The sorceress casts a horny spell which ordinarily wouldn’t do much but in conjunction with everything else it might be enough to get the swimmers and gym rat fit chick female bodybuilders to start flirting with the men.

Then the three women can slip through with a nice vantage of the flirting and presumably sex the orc can get another boy toy and if anyone gets in the way they can flirt their way through.
