Beg for release

You meekly speak up "I..I was hoping you would...let me.." you look down at your twitching cock.

She understands "You want me to touch that thing? Don't be absurd" she replies, still a little red in the face.

"Please...can I..I need to" you continue pathetically.

She sighs and stops to think. "Fine...just...do it yourself. But we will never speak of this again? Am I clear?"

You nod and eagerly start to stroke your cock. On your knees and wanking over your teacher. This is not how you thought detention would go. You look up at her in awe, and she looks down at you, hands on her hips, with disgust and embarrassment. That just gets you off more. You barely last 30 seconds before bending forwards, one hand on the floor to support yourself as you cum. Miss Locke chuckles softly as you moan.

"Ok, now get out of here you horny brat" she commands.

You gladly obey, putting your clothes back on while your cock recovers. Smiling to yourself, you leave the class and head home.
