You are almost done grading the papers when there is a knock at the door. You look up and see Danna standing there. She's a tall girl with black hair, and is old for the class. Nearly 19. She has a December birthday and was held back a year because of it. Her black hair is tied back in a ponytail and she wears a golden sundress You've seen her a lot lately with Maddy. They are both about as bad as one another grade wise. You graded Danna's test earlier. 32%. She's gotten only a 51% in your class and will have to retake it.
"Hi Mr. D" she says as she comes into your office, sitting in the guest char and putting one foot up on your desk. You sigh inwardly. "How'd I do?"
"Unfortunately Danna you didn't do well enough on the final exam to pass the class. You're going to have to retake it next year."
"Oh" she says "well how did Maddy do?" she asks.
"I'm afraid I can't discuss the grades of other students with you" you say as you move the stack of exams into your folder. "Is there something else I can do for you?"
Danna has an odd look on her face "Maddy seems pretty confident she is going to pass. She... told me about her studying technique."
You freeze for a moment then continue packing your bag "oh?" you say.
"Yeah. She says you are actually a really good... teacher... if you are given a chance. I hear she is planning on taking that College Prep course with you over the summer. I think she's probably right, and I think I've decided I want to take it with her as well."
"Unfortunately you won't need College Prep just yet. Maybe you weren't listening, but you aren't passing this class, and if you don't pass, you don't graduate."
She stands up. "Are you sure I didn't pass?" She pulls up her golden sundress revealing her bare shaved pussy lips beneath. "Maddy said you were a good... tutor. Maybe if you look over my... exam... again, you'll find I did better than you expected. And maybe this summer you can tutor both of us... together?" she says.
This is starting to get out of hand... "Danna, I-"
"Here," she interrupts "let me show you." She walks around to your side of the desk and sits on your right leg, straddling it as she leans over your desk. You can feel the soft flesh of her round ass and supple pussy, sliding over your leg as she scoots back. "Maddy said you might need to show you were that grade is, so, take a look, it's right..." she grabs your hand and pulls it up to her face. She slides your index finger into her mouth, making a sucking motion against it. "...here..." she pushes your hand down, under her dress and up.
You take over from there. You slide your hand up between her calves, lightly sliding your spit covered finger between the folds of her pussy lips. You sink it in, parting her pussy lips and plunging your finger into her tight and warm teenage pussy.
You thrust in with the finger, exploring her insides. Her hips rock lightly back and forth with your touch, rubbing her naked ass against your leg. You lean forwards, wrapping your other arm around her and grabbing a small breast in your hand, massaging it. You put your chin on her shoulder and turn your face towards her ear. You whisper "let's take a look then." You kiss into her neck as you roughly massage her breast, pulling her into you so her ass slides against your stomach and driving your finger deeper into her hole.
You start panting as your desire for her young body flares. You let go of her breast and jerk your hand forward onto the table. You grab the neat stacks of exams and give it a shove, spreading them out across the desk. You fumble through the scattered stack until you find Danna's exam, a big 32% scrawled across the top. You place it in the center of the table.
You reluctantly pull your hand away from her crotch, immediately missing the tight suction of her hole as your finger comes out. You grab hold of her ponytail, wrapping it into your hand and roughly pushing her head down so she bends over the desk. You stand up behind her and forcefully push her head the rest of the way down, so her face slams into her exam, her eyes pointing right at the 32%.
