Two-for-one seduction

Robin knows that he should stop.
He should run and call for help.

For some reason, however, he stays there and lets the villains control him.

It might be due to the gas being emitted throughout the place.
Then again, it might be due to him having two handfuls of tits for the first time in his life.

He softly fondles Harley's globes, while she moans.

Ivy is slowly undressing Batgirl, sliding her pants off and pulling her top up.
Catwoman helps her out by pulling her away from the others.

Robin's night gets better as Harley undoes his pants and they fall down.
Simple black briefs cover his manhood...for now.

Speaking of stripping, Batgirl has lost her cape, allowing her top to be removed.
They leave her mask on, since, for one, it won't trigger her fight or flight response.

Plus, it is kinkier to take her with it on.

She's soon down to just her underwear, her boots and pants lost for now.
Catwoman kisses her all over.

Robin is now naked from the waist down, thanks to Harley.
Ivy kept him busy by letting him touch her tits for a bit.

Soon, however, she's raised his hands over his head and holds them there.
Below, Harley wraps his cock in her tits and fucks him that way.

He soon cums.

His legs go weak, but Ivy holds him up.
Harley licks his seed up from her tits and smiles.

She gets up and they guide him to a nearby bed.
