Kick her out

You wait until you can feel she’s finished swallowing before you pull your softening cock from her mouth. She falls to the floor, gagging and gasping for breath. You drag her out from beneath the desk and watch her try to catch her breath. “That was C, C-plus cocksucking at best, Miss Derrick. I would’ve expected better from a dedicated student like you,” you say. ‘Now get out. You’ll be late for your next class.”

As she pulls herself to her feet she looks at you, dazed, with either nothing to say or no breath to say it. After a moment, she turns and staggers toward the door.

“Oh, and Miss Derrick,” you say before she leaves. “If you start thinking about teacher’s long, hard cock again, come see me. I’ll show you what teacher’s cock can really do to a little slut like you.”
