You and your teacher were in a a secret relationship... It's been like this for a couple years now, he's 31 you're 17. This started when you were 15, no one has found out,
Like usual, he asked you to stay after class since you usually pretend to "misbehave" to see him longer, but after a couple minutes of being alone with him students came to class earlier then he thought..
He got you to hide under his desk so no one could see you, he sat in his chair, your head next to his legs as he started teaching the class. When the students were distracted he looked down at you trying not to bring attention to you and himself.
He moved his hand towards your chin, moving your head to look up at him, a smirk spreading across his face as he looked down at you. After a second it quickly fades as he hears a student call for him
"Yes, what is it?" he asked .. clearly not really caring.
"Sorry sir.. But I'm confused on this question " The student responds
He stood up, dropping something on the floor next to you before walking over to the student
