Obedient, but not Okay

You spot a jogger heading towards you. She is tall and lean with long blonde hair in a pony tail. She's wearing pink jogging pants and gray t-shirt over a sports bra. She looks to be a few years older than you. As she nears you, you test out if what happened was real or a dream. "Stop and give me twenty!" you say. You do not know if she is going to flip you off or what.

The girl stops. She looks unsure of herself then steps off the jogging path and onto the grass. She lowers herself to her knees then gets in push-up position. She starts doing push ups. "What's going on?" she asks.

"I don't know," you say, lying. "Looks like you're doing push-ups."

"But why, and why can't I stop myself?" she asks.

"Maybe you just love obeying strangers in the park," you say.

"No, it's...what's going on?"

You wait until she finishes. She stands up and is red in the face. You wonder how turned on she is by the sound of your voice.

"Twerk for me, baby," you say.

The girl turns her back to you, bend over and starts shaking her ass. "How are you doing this?!" she says with fear in her voice.

"Just keep twerking until I say 'stop,' and smack your ass while you do it."

The girl reaches back and smacks her twerking butt. "Please, stop!"

"Stop what?" I ask. "I'm not holding a gun to your head."

"Why am I doing...what...you say?" she asks before smacking her ass again.

You notice her voice now is breathier, and you know your voice is getting her aroused.
