She simply acts.

Batgirl simply smiles and slinks over in front of you. Without a word, she plants her pussy on Wonder Girl's face!

She points down at your dick and then to her mouth. She licks her lips.

You nod and pull out of Wonder Girl's pussy. Your moist cock pops free and hangs over now-empty pussy.

Batgirl flattens her body out, pressing her boobs into Wonder Girl's stomach and takes your cock in her mouth.

To tell you what to do with her mouth now occupied, the Heroine reaches forward and pulls you forward by way of your ass!

Taking the hint, you start to fuck her face!

As a side effect, your balls slap against Wonder Girl's clitoris, now enlarged due to two orgasms in the last few minutes. Bonus!

The first to cum is actually Batgirl, since she worked herself up so much while watching you two.

Wonder Girl cums next, aided by her raising her own hips to grind against your balls all the more!

Finally, you cum, giving Batgirl a warning by squeezing her shoulder. You shoot your load into her mouth and she manages to hold it all.

When you're done, you step back and watch Batgirl slide off of Wonder Girl and hover her face over her friend's. The two then proceed to share your load between them until they are done.

"Okay, we are DEFINITELY not telling Batman about this," you say, causing the duo to laugh with you.

You see that the Doctor is still **** and contained on the ground. You re-dress as best you can and each borrow some lab coats from a rack before heading back to the Watchtower.

Hopefully an interrogation of the Doctor can lead to some new intel (and fun)...
