Nevermind that, what about the lasso?

John looked back and forth between Starfire and Diana, or more specifically, Diana's lasso. It's not as if he hadn't noticed the change that had come the orange tinted alien while Diana had it wrapped around her.

"Diana." He said. "Just how powerful is this new... ability you discovered with your lasso?"

"I'm unsure, master. Though from what I've seen, the effects can be..." Diana thought back to the woman getting **** in the park, now no doubt a proper obedient cum dumpster. "drastic."

"Hmmmmm, have you experimented with it at all?"

"No master, I have not."

John looked down at Starfire and smirked. "Why not start then?"

Starfire looked up at him quizzically. "Start what, daddy?"

"Oh nothing Star, I just need you to let Diana tie you up again." He put his hands gently on her shoulders and eased her away.

"Why do you require her to do this?" The Tamaranean tilted her head and blinked at her new master.

"Just humor me star, I do own you after all." John said with a smirk. Just saying it caused his cock to twitch a little. His newly discovered sexist streak was doing wonders for his libido.

"Very well... I suppose I do not have a choice." Starfire said, clearly uncomfortable with the idea.

She tied it perhaps just a bit tighter than she needed to, and she was perhaps rougher than she needed to be tying it off. The barest twinge of jealousy gnawed at her. Not that it was her place to be jealous, her master was well within his rights to take multiple slaves after all.

She double checked that Starfire's bindings were secure, then took her rightful place by her master's side.

"Well done, Diana." John said. He rubbed his hands together at the hint of fear on Starfire's face. "Now, let's get started..."
