The classroom is empty, save for the two students left behind to clean up after a long day of lectures. The girl, a petite blonde with a smattering of freckles across her nose, is bent over, wiping the blackboard. The boy, tall and lanky, watches her, his eyes lingering on her round ass, visible beneath her short skirt. He swallows hard, his cock twitching in his pants. He approaches her, his steps silent on the worn linoleum. She straightens up, feeling his presence, and turns to face him. He doesn't say a word, just reaches out, his hands going straight to her hips, pulling her close. She lets out a soft moan as he grinds against her, his hardness evident through his jeans. She reaches down, cupping him, feeling him throb in her hand. He grins, his hands sliding up her sides, pushing her shirt up, exposing her lacy bra. She gasps as he unhooks it, her breasts spilling out, ready for his touch.
