Madeline threatens to post it

"What an adorable picture," says Madeline, tapping a button on her phone to save the image of your humiliation forever. There's an impish grin on her face. You stand before her, hands folded over your dick in a pathetic attempt to conceal the obvious evidence of your arousal. "What do you think we should do with it?"

"Don't do anything with it!"

"Oops. Accidentally shared it in the group chat."

"No!"

"Kidding! Maybe." Madeline sticks her tongue out at you, clearly loving every second of your discomfort. "But all I have to do is click this button, and the whole world gets to see you playing with yourself like a dirty little pervert..."

"Please don't!"

"It's your own fault, you know. Walking around naked in broad daylight, touching yourself in front of an innocent girl like me. What did you expect?"

"You said you wouldn't look!"

"I was joking, obviously." Madeline shrugs, her finger still hovering over the button. There's a wicked glint in her eyes as she ogles you. One of your hands cups your balls, the other tries to shield your cock, but you're big enough and hard enough that it's difficult to shield yourself from her intimate inspection. "I guess I'd better save this to the cloud, so you don't get any funny ideas about trying to take my phone away."

"I won't do it again! I promise!"

"Too late now," says Madeline. She looks thoughtful. "I probably should post it. Women need to know there's a naked pervert running around town. Unless..."

"Unless what?"

"That's a good question. I guess I could pretty much make you do anything I want..."
