BDSM with mr. Kingsley

Please sir...

He approached my desk slowly. " Is this a joke" he roared. I jumped slightly Cuz I was caught off guard.
"I'm not sure what you mean Sir" I said quietly. His eyes softened. "I didn't mean to scare u" he said. " It's ok" I lied.
He gave me a odd look. Then he nodded his head and walked back to his desk. Kids started coming in so he introduced himself all over again. And this time instead if world war 2. It was chemistry. I was bored as hell so I started texting when my phone was snatched I looked up to see a angry Mr Kingsley. "Detention" he said.
"Oh hell no.... Its the first day back. " I said.
"Well then you should've waited until someone's else classroom to text your buddies" he told me glaring at me.
"Whatever" i mumbled as i sunk down in my seat. He winked and walked away from my desk. I wonder what it was about. I spent the rest of his class glaring at the back of his head.
