They do

The Batplane flies across the sky with three passengers carried past Gotham proper to the Wayne Manor. It soon lands and emits a noise to wake up Batman.

Batman's eyes fluttered open as he began to wake. He looked over to the still sleeping body of Wonder Woman and smiled as he remembered the dream he had been woken up from. Batman took a breath as he stood and moved over to the amazon, "Diana, you need to wake up," he said as he shook her shoulder.

She blinked once looking into Batman's face and shook her head slightly, as if trying to shake away a dream, before she reached out to hug the caped crusader. "Master," Diana said, "I thought this may have been a dream."

Batman smiled as he returned the hug and stood the woman up, "Not a dream," he said, "Not yet," Batman moved over to the passenger door of the plane, "We're back, head inside and get some rest, we have more to talk about soon."

Wonder Woman blushed slightly and said, "Yes Master."

She walked toward the open passenger door, kissing Batman as she passed him, "I think I'll enjoy our, "Talk"."

Batman smiled as she walked down the stairs out of the plane, 'I think I will to slave.'

Batman moved into the cockpit of the Plane and saw the scene he had left a few hours ago. Zatanna was tied to one of the chairs with a vibrator in her cunt and a gag in her mouth, after she had passed out for the third time Batman had enough and decided to just torture his new slave with overstimulation. He had left her being teased as he checked on Diana, 'I guess I ended up doing more than check on her.'

Zatanna was teased mostly out of her mind, her eyes couldn't focus, her gag, her panties, were soaked with her drool, 'Completely helpless,' Batman thought, 'Just how she should be.'

So now Batman was face with a question, take advantage of his toy's vulnerable state, or play the gentleman and seduce her more thoroughly later on?
