Suggest to spank her.

"Hey," Simon came up with a brilliant idea, eyeing her tennis racket. "Are you using that?"

Pausing her chest shaking, the tennis woman looked to her racket curiously. "Not at the moment."

"Oh great." Simon clapped his hands together. "Does that mean I can spank your ass with it? As hard as I want to, too?"

A look of positive delight took her face. "Oh my god. Yes!!" She quickly got up and passed Simon the tennis racket. "This is such a great idea." She bent forward. "Especially out here in public for everyone to see!"

Simon agreed, and lifting her racket, swung it down hard against her presented bottom. She grunted out in pain, but followed with a word of approval. "Yes, there you go! Keep it going, mister! As hard as you want, okay?"

Couldn't argue with that!

smack!

"Ooh!"

smack!

"Ow!"

smack!

"Oooh god," she laughed through her ragged breaths, looking back playfully at Simon. "I can't believe I never thought of asking anybody to do this before. This is such a great, alternative use for tennis rackets -- spanking asses like mine!"

Simon gave her butt another smack and cried, "Damn right!"
