This isn't Kitty's first time doing this.

Starfire kisses Raven tenderly.
Raven submits to this.

Even so, she's nervous with Kitty and the men watching.
Especially after...

"Fan Fiction come to life. You just know how much of it involves you two making out."
They've seen a few examples, yes.

'It is hot,' Starfire says.
'I...don't know how I feel about it,' Raven thinks.

"Don't feel too shy. You aren't the first Heroines to perform like this here."
They stop kissing (although Starfire holds Raven close, their tits touching still) and look at Kitty.

"It's true. Hey Creedo, play my favorite clip from last night."

A screen activates on the wall to her right and the duo are shocked by what they see.

Supergirl and Batgirl are naked on a bed.
They are making out happily!

'What the hell,' Raven thinks.
'It's about time those two finally hooked up,' Starfire thinks.

"Did I say to stop kissing, by the way? You can do it and watch."
Starfire pulls Raven back in for a kiss while they watch the duo in action.

They grind on each other and both cum from their pussies rubbing vigorously.
Supergirl ends up on top...

...before she asks the men to come over and fuck them.

"Your turn now. No orgasms though- you two lost that privilege."
Stafire and Raven share a look.
"I have to," Starfire says, simply.
