Not just yet.

Raven makes no objections as you start to fondle her ass while you lick her out.
So far so good.

In front of you, 'Starfire' is nearly at orgasm.
You wonder if Raven will stop at just one.
Hell, will 'her friend' let her?

She moans more.

The pair are really enjoying themselves.

"...well, that helps your case quite a bit," Raven says, still panting, "Tell you what- let me see you fuck her and we'll see what happens."
You nod.
"In that case," Starfire says, "I want him to..."
