Bat Trap

Robin was 19, had an updated costume and really wanted to stand out on his own.
Batgirl was 20, wanted to stand out as well and was worried about just becoming 'one of the family.'

They worked together to track down a recently escaped Harley Quinn and Poison Ivy.

Batgirl stays on a nearby roof outside of the Penthouse, while Robin sneaks in.

He's ready for Harley's hammer and Ivy's toxins.

He's not ready, however, for what he sees.

Robin sees Harley doing a strip tease for Ivy, dancing around to strange music.
When she spins around (with her eyes closed), he sees her big tits.

Those pants are tighter than ever!

Nearby, Batgirl gets a different view, seeing the equally undressed Ivy.
She's getting wet.

She doesn't hear Catwoman sneak up on her...

Inside, Robin watches the end of the show, with Harley teasing pulling down her panties.

"Should I finish up, Boy Wonder?"
"More like Man Wonder," Ivy says, looking at his bulge via a reflection.
"I don't...I mean..."

Ivy and Harley invite him in with matching gestures.
He awkwardly enters.

Right on cue, Catwoman leads Batgirl in through a side door.

She sees the others and unzips her, well, catsuit.

The trio lead the young Heroes together.
Ivy plays with Batgirl, lost in lust via an unknown (to Robin) injection of a chemical.

Harley takes off the nervous hero's glove and presses it to her breast.

The night is young.
