Ass

"I haven't taken your ass yet," Bruce said taking out his dick, "Now bend over."

Diana bent over Zatanna's desk and wiggled her ass slightly before she, with her most innocent voice, asked, "Like this?"

Bruce growled as he closed the distance between them and lined up with Diana's entrance, "Yeah, something like that."

Bruce pulled Diana's hair as he thrust into her, pulling out a gasp and a moan. He began kissing up and down her neck as he continued thrusting, placing hickey's on her, 'Marking my property,' he thought as he placed more hickeys. Bruce bit lightly on her ear and tugged on it softly as Diana moaned underneath him.

Diana panted as Bruce penetrated her over and over again, she could feel with every thrust she felt a little bit weaker. 'Maybe he'll fuck out my powers completely,' Diana thought feeling her first orgasm approaching, 'That could be nice, then I could just be his nice, domesticated, little, house slut.'

Bruce felt stronger with every thrust and could thrust even harder, eventually though he reached a plateau and could feel that he was not growing any stronger. 'So either I've fucked her to the point that her powers are gone, meaning that they will need to regenerate, or there is a limit of how strong I can get from Diana alone.'

Bruce could feel Diana orgasm around his cock, she tightened the muscle's in her ass and clenched on Bruce's penis, this brought Bruce over the edge. Bruce flooded Diana's ass with cum and could feel her go temporarily limp in his grasp, but Bruce wasn't done yet so she wasn't allowed to rest for long.

He soon woke the woman and fucked her again, and again, and again. By the time the four hours were up Zatanna's changing room had a permanent smell of sex, and Diana couldn't walk straight.

-When Zatanna returned-

'Oh my god,' Zatanna thought as she walked back into the room. She could smell it before she could see what happened, sex and cum, 'Bruce's cum,' Zatanna thought, 'I wonder what it taste's like?' Zatanna shook herself away from that thought and observed the room.

Diana looked like a schoolgirl who was caught doing something naughty, head tilted slightly down face abashed, hair all in a mess, and she refused to meet Zatanna's gaze.

Bruce looked very different, a satisfied smile on his lips, and his eye's slightly glazed over.

"Have fun," Zatanna asked causing Diana to blush and Bruce to let out a short chortle, 'Is that what his laugh sounds like?' Zatanna thought, 'It's nice.'

"I think we're ready to go if you are Zatanna," Bruce said putting a hand around Diana's wast.

"Oh yeah, I had plenty of time," Zatanna said, causing Diana to blush harder.

"Ok then," Bruce said, "Off to the Batplane."
