As the teacher, you enter the classroom after hours, anticipation thick in the air. The rebellious student who'd been causing trouble is waiting for you, kneeling demurely on the desk with her skirt hiked up. She looks small and vulnerable, yet there's a hint of defiance in her eyes. You walk up to her, feeling the heat radiating off her body.
Slowly, methodically, you pull down her panties, revealing her bare, quivering ass. You can't help but admire the way it curves enticingly around the edge of the desk. Without further ado, you pull out your throbbing cock and position the head at her tight, puckered entrance. She flinches slightly but remains still as you push inside, feeling her delicate walls grasp at your length.
You begin to thrust, slow and deliberate at first, savoring the sensation of being so deeply connected to her. Your hips rock against hers in a rhythmic motion, and she gasps softly, arching her back to meet your movements. As you pick up speed, her nails dig into your shoulders, urging you on, and you can feel her climax building.
