A strange contract

"Wider," he said. As he held a sharpie in his hand. "Don't move."

He wrote in sharpie on my hips and inner thighs in scrolling, loopy cursive. I couldn't read it from my vantage point. Immediately above my pussy lips he wrote something I did recognize-his signature-.

"Give me your phone," he ordered.

Shaking, I reached into my backpack and pulled it out. I opened my mouth to protest but he cut me off.

"I'm not calling anyone, my slut. I'm not sending anything. Give me the phone."

He took a picture of me with my legs spread, pussy exposed and covered in his writing. He turned the phone to show me what he'd written.

"I promise to grant extra credit of 20% per day she proves to be an obedient slut. - then signed his name"

I couldn't stifle a moan. The picture didn't show my face but I love seeing his writing on me like he owned me. He returned the phone to me and I tucked it away in my bag.
