Yes!

As you tongue kiss the bound and naked Raven's pussy, the power your body copied from Raven activates.

The knowledge of Raven's magical language and spells floods into your brain! Dark stuff.

Using what bit of will you have- drained by being fucked by both ladies in the last several minutes- you quietly whisper Raven's magic words and focus on a small thing- the gag around Raven's mouth.

Starfire is engaged in riding your cock and fondling Raven's tits that she doesn't notice the energy being exerted on the cloth. Slowly, but surely- using more energy than you would normally like- you undo the back of the gag (which is facing you)...

It finally comes undone, allowing Raven to spit out the panties in her mouth!

As Starfire realizes what happened, she quickly goes to block Raven's mouth. Too late!

"Azarath Metrion Zinthos!"

Magical bonds quickly encompass Starfire's wrists and they are pulled together behind her back. She also makes a magic ballgag appear in her mouth- not that it is actually necessary. She just wanted to!

"Quick- undo my wrists now," you exclaim, "We can properly punish her together."

Raven uses her magic again, undoing the ropes on both of your wrists. She makes it look easy!

"And now for mine," Raven says, "Azarath Metri-MMPH!"

You suddenly grab her mouth, shoving the panties back in with one smooth motion. You hold it closed with the other hand.

"Actually, I'd rather you both be bound for a while," you explain, "Now get back to fucking yourself on my dick, Starfire. As for you..."

You focus more directly on pleasuring Raven this time, with no ulterior motive or distraction. You quickly drive a small orgasm out of her, but don't let up.

Moments later, the pair both cum again! Using your extra body control from the Nanites inside of you, the orgasm you were facing is held back- for now. No sense losing control just yet.

Now for some real fun...
