He helps her demonstrate

"I don't think your demonstration was very clear. Perhaps if we do it for real, it will benefit young actress's more." John said, climbing over the velvet rope.

"That's a great idea, how kind of you to offer." Keira said, getting back onto her hands and knees. John realized he wouldn't be able to pull the tight dress all the way up, so he grabbed the end of it and ripped it upwards enough to expose her ass. He looked at Keira, bent over in with her red lacy thong on display to the world and smiled. He grabbed the thong and pulled it as hard as he could, tearing it off her, which she didn't mind at all. She reached back and pulled her butt cheek with her hand. John did the rest, helping her to spread her cheeks before slipping his dick into her anus. It was clear she hadn't really done this very often by how tight it was, but she was still acting like she did it all the time.

"Oh yes!" She shouted, "Spank me!"

John didn't hesitate, and spanked the side of her ass as he thrust into her, on the red carpet.

"Pull my hair!" She shouted, which John did, hard. He thrust in and out of the tight asshole while Keira moaned in pleasure and the cameras caught all the action.

Then John remembered what Keira said about cumming anywhere he wanted.
