A/N: Slade and Robin live together in a penthouse overlooking Jump City. Basically just smut.

If anyone didn't know, to "christen" a place in this incident is to have sex in every one of the rooms.

Slade and Robin opened the door to their brand new penthouse, keys jingling in the lock. They'd signed the lease on the place a week ago but waited until now for movers to finish arranging the furniture. Robin took a deep breath and coughed.

"Wow, this place reeks!"

"It's musty." Slade explained. "This complex hasn't been occupied in years."

"I don't see why not! Look out the window." Robin had pulled back the dull gray curtain, revealing a huge expanse of glass panes and the gorgeous view of downtown Jump City, as bright and as busy as always, people coming and going in the streets.

"It's all ours to look at," Slade said, coming up behind the small boy and wrapping his arms around him. Robin blushed and tipped his head back, accepting the kiss Slade planted on his neck underneath his jawbone. Robin turned in his arms, kissing him back fiercely.

"Want to christen our new place?" Slade asked Robin, and the boy raised an eyebrow.

"What would that entail?"

Slade pushed Robin against the window, a devilish grin on his face as he moved his hands down to the boy's waist. With one deft movement, Robin's pants were off and thrown to one side, his shirt soon following.

"Slade!" Robin protested as the man pressed him back up against the glass. "There are people down there!"

"So?" the man dismissed, unbuttoning his pants. "Give them a show."

Robin blushed, spreading his legs as Slade coated his fingers in lube. The man worked one finger inside Robin quickly, the hero making a small keening noise until another finger was added. Slade took his time stretching the boy, enjoying the gasping noises he made and the way his ass squeaked against the window.

"Slade," Robin moaned, wrapping his legs around Slade's waist. Slade removed his fingers and buried himself inside the boy.

"Pity they can't hear you," Slade whispered into his ear. "But I guess your ass getting fucked is enough of a display for the entire city."

Robin couldn't help a needy moan as Slade's words washed over him. If anyone on the street down below happened to look up, they would be able to see the boy clearly. They would know exactly what he was doing.

Slade pulled out and, before Robin had time to complain, Slade had flipped him over, pressing his front against the cold glass, thrusting into him once again. Robin made a strangled noise as he tried desperately not to come, the chill emanating from the glass combined with the pressure on his prostate almost too much.

"Don't hold back," Slade purred in his ear, knowing what Robin was trying to do. "Come for me. Come in front of the entire city. Give them a little show. But remember that you're mine. And I. Don't. Share."

Crying out, Robin came hard, splattering the window with opaque fluid, Slade coming one beat behind him.

"So," Robin panted, trying to catch his breath. "Next room?"

Slade chuckled, carrying the boy to the bedroom and shutting the door.
