In a dimly lit classroom, the young student is cornered by his mature teacher, her eyes smoldering with lust. "You've been a naughty boy, haven't you?" she teases, running a finger along his collarbone. "But I think I can help... with a little extra credit." She unzips her dress, letting it fall to the floor, revealing a black lace bodysuit. The student hesitates, then tentatively touches her breasts. She moans, "That's it, my little student. Show me how you can make the grade."
