Input: Text: this happened last friday. i'm an 8th grader and i'm going to a private school. my teacher has always hated me. she always failed me, criticized me, and given me more detentions than i can count. it's partly my fault because i don't study or do homework. one time, i paid attention in class and got the highest test grade in class. i've even outsmarted the nerd in our class! he got 90 and i got a 94! my teacher thought i cheated, and ended up giving me detention. after school she would make me do homework and clean up the classroom. one time, she even made me organize her drawers, which i think she made a mess of on purpose. last friday, i was bored and made a paper airplane and i threw it from the back of the classroom, while my teacher was explaining something and drawing something on the board. it flew high and took a sharp left dive right into her right ass cheek while she was explaining something. everyone was laughing and i couldn't help but laugh too. she was furious. i thought i was going to be sent to the principal for sure, but luckily she only gave me detention. in detention, she made me clean up the floor for a little bit and wash the white board. finally, i was done and i'm happy that i get to leave now. she told me to tape the thanksgiving decoration strips to the rectangular window crack on her door. i did and as i was putting the tape back, she said "sit down, we have to talk. so, i see a chair next to her desk that she put up and she just went up to lock the door from the outside. oh boy, this is going to be bad. she came close to me and said "keep your mouth shut, or else you won't be graduating. now don't say anything, just apologize" i tried saying something and she quickly walked over to me and sealed my mouth with her hand. she said "shut up" and pulls her pants off, brings her right butt cheeck to where i hit her with the plane and said "that hurt and now you're going to have to kiss it." so i kissed her butt cheek and then she lets go of my head. she says "you're not done yet, keep your mouth shut or i'll fail you." she goes on top of her desk and completely takes off her pants. she tells me "come here" so i came closer. she grabbed my right shoulder and pulled my shirt. now, i'm betweeh her legs and pointed to her panties and said "take them off." so i did and then she grabbed my head and pushed it on her vagina and said "lick it" so i licked her and she told me where to lick her and even made me put fingers inside there. she said that she'll fail me if anyone finds out and that she's keeping an extra eye on me at all times. this isn't the worst punishment she's ever given me, but the most humiliating. i'm sharing this with you because i don't want you to go through what i'm going through. please study and listen to your teacher so so this wouldn't happen to you. i so not look forward to going back to school tomorrow.

 
don't be a bad student or else the teacher will hate you and give you lots of detentions and fail you and make you do stuff you don't want.
