She doesn't

"Well, maybe I can solve it later. If you are a good boy and deserve such a thing. Maybe you just deserve to suck my cock and let me use your holes as I please." She grinned and took her foot off of your chair standing up fixing her hair. She slipped her shrinking cock back under her shorts and walked toward the door turning the lights on and unlocking the door.

"Wait, please im so fucking hard" you gasp as she unlocked the door.

Her only response is a giggle as she turned her head back and flashed you a bright smile. "Good, don't you dare make yourself cum. I'll be around after school for a ride home."

With that she walked out the door and shut it behind you as you gasped leaning on the desk trying to think of anything but of what just happened. You can't believe you just sucked the cock of one of your students. Your brain could barely comprehend what just happened. Just a couple of hours ago you were a purely straight guy who had never really thought about sucking a cock and now...thats all your mind could think of. You wanted to suck her cock again, you wanted to please her any way that you could.

But she would be back before the end of the day and its ten minutes before lunch is over and the students begin to wander in. Do you fix this hard problem in your pants yourself or are you a good boy?
