(Your OC was running incredibly late for class for some reason. Their teacher was a bitch, but she was a fucking sexy bitch. She often wore her shoulder length mane in a bun, a black pencil mini skirt, a white button up shirt, and black high heels.)

Eruption *She was writing an assignment on the board.*

Hapling *scampered towards the door to his classroom, tripping over his long tail. His mane, tail, and neck-tuft are light gray, and his coat is pale blue, almost white, as do his antenna, which have purple tips. His eyes stand out, being bright pink. His moth wings have a white membrane, with red hollow triangles interlocking into a circle, with cyan dots in the center.* "Let's hope she doesn't kill me..." *He said as he opened the door as one normally would.* "I'm sorry Miss Eruption for being late. I have a legitimate excuse this time."

Eruption Let's have it. *She finished writing the assignment.*

Hapling *nods, sitting in his chair* "There was a gas leak from the stove at my house yesterday night, so my mother woke up everyone and quickly got us out before we suffocated. We had to wait in our car for the authorities arrived to repair it." *He said, looking directly at her eyes, to avoid looking 'elsewhere'.*

Eruption Alright. I'm surprised you came to school in such situations. You are excused.

Hapling *nodded* "Thank you Miss Eruption."

Eruption *She sits down at her desk and began grading papers.*

Hapling *looks at the assignment, wanting to get started.*

Eruption *She grades papers and helps a few students until the bell rings, she dismisses the class.*

Hapling *stands quickly, and helps one of his friends.* "We still on for movie night at my house? My mom's new electric stove she installed two days ago should pop the popcorn in record speed." *he said aloud to his friend, unaware of the fact Eruption heard him blatantly take apart the gas leak-excuse.*

Eruption I doubt you'll enjoy popcorn with a "gas leak" and a call to your mother. *She pins him with her crimson gaze, crossing her arms*

Hapling *sighs, realizing his mistake.* "Whoops..."

Eruption *She drums her fingers on her arm as the other students file out of the classroom, a student shutting the door.* I don't appreciate being lied to, Hapling...I think that my lectures aren't really doing anything, so I think you need a punishment.. What that punishment is...I guess we can both decide what it'll be and each time you're late, you'll receive that punishment.

Hapling *gulped, his antenna drooping a little.* "What is it? Detention?"

Eruption While Detention was one of my ideas, you showing up late has caused more stressful work for me because I need to get the work you missed as well as work for anyone that's absent.. You could possibly make less work for me and get your grade up by getting on your knees under my desk and showing that your clever tongue can do more than make excuses~~ But you can easily opt for more work and still benefit, I'll simply be left to go find someone else to relieve me of my stress.

Hapling *His eyes widened and his antenna quivered visibly. His bran definitely liked the sound of that, but his mind wasn't so sure* "A-A-Are you s-sure?"

Eruption I am, I've thought about this for a while. No stallion my age can really do anything for me, so I thought I'd try one of you students. But as I said, I hold you to nothing, You can still improve your grade with extra credit work.

Hapling *thinks for a second, and then nods, approaching her desk.* "A-Alright, I'll do it."

Eruption *She smiles* Great~ Lock the door and we can start~ *She pulls off her panties*

Hapling *he does so, closing it quietly. He then returned to her desk, crouching under it and looking between her legs, smelling her scent with his nose and antenna.* "Mmm~ that smells delicious~"

Eruption *She blushes faintly and watches him with a lustful gaze.*

Hapling *extends his normal tongue out, slowly drawing it up her slit to her clit, which he flicked with the tip of his tongue before licking back down and repeating the process.* "Mm~"

Eruption *She gives a low moan and rests her hand on his head.*

Hapling *He murrs a little, taking a deep sniff,pressing his snout against it as he did.* "Mm~! So good~!"

Eruption *She gives a lustful shiver, spreading her legs further as she threads her fingers through his mane.*

Hapling *purred, enjoying the touch. He slid his tongue into her folds, licking around inside, relishing the taste.*

Eruption A-Ah!~ Hapling~ *She moans his name as her hips jerk at the pleasure he caused.* Your tongue is f-fucking amazing~~

Hapling *gets an idea, and benign to slide his proboscis into her folds, sucking up her secretions and wiggling around against her walls.*
