"Cum all over her."

"She's happy to be used like this," Raven explains, "She's happy that it makes you happy...and that it makes me happy.
So would you please cum all over her?"

You nod.

You pull out her mouth and give your cock two quick jerks.

You cum on Starfire's face.
You cum on Starfire's neck.
You cum on Starfire's breasts.

At the end of that, you notice some odd body motions from the Tamaranian too.

"Thank you. Now let me show you why we really like this," Raven says.

She unhooks Starfire's arms with her legs and gets on the ground next to her.

The pair begin to make out, with Raven making sure to lick up your cum.

Starfire shoves Raven's face into her tits to lick them clean as well.
Of course, she does more than that- naturally.

The pair finish and look up at you.

"One question- did she just, you know, cum from me cumming on her?"
"I did, yes," Starfire says with a smile.
"I told you that she liked making us happy. It's also a thing her people can do."
"They can...cum on command."
"It's not quite that simple," Raven replies, "But, mostly, yes."
"Good to know. So that means that one of us here hasn't cum yet."
"That's true- any suggestions?"
