Daddy's Girl Has Bad Grades

This is a short story about my 17 year old Amy who is in high school, but is not doing well in her classes. She came home after school one day... 

"Darling, I am very unhappy with the report card you are showing me. I am very disappointed. I told you if you fool around and cannot get your grades up, there will be more punishment."

Amy apoligized: "I am sorry daddy, I will try harder next time, I don't like to disappoint you."

"Sorry is not enough honey," I say, "do you remember what happened last time?"

"Yes daddy", says Amy, "you pulled down my skirt and undies and you spanked me. It hurt."

"That's right darling, I am going to punish you harder this time to teach you a good lesson."

I take Amy by the wrist and bring her to the table. I ask her to turn around and put her hands on the table. I grab both sides of her hips and pull down her skirt then I slap her bum cheeks with my hand and hit her again.

"Ouch! Daddy it hurts", she cries out.

I stop. Without saying a word, I look at Amy's undies. They are so cute! They look so innocent!

I carress her slightly reddened bum. Amy looks at me curiously. I gently pull down her undies.

"Daddy what are you doing", asked Amy suspiciously.

"Shhh darling. The punishment is not over yet." As I say that, I start taking off my belt.

"No daddy, please not with the belt! Please daddy!"

I take off my belt completely and throw it away on the floor. Amy breathes out in relief. Moving closer to her bum I press my hips against it. Amy's eyes widen! She cannot believe it! She feels my hard cock pressing against the crack of her bum and gasps!

"Now I am going to punish you like you have never been punished before!"

As I say that, I pull down my pants and take out my cock. I come close to Amy, grab her hands inside mine, and press my body firmly against hers. I hold her very, very tighly as I insert my cock into the crack and press it against her anus. I press more and more firmly... until her asshole gives in to the pressure, opens up, and lets my hard cock in.

Amy gasps: "Aaaaaaah daddy!"

"I am going to punish you in a hurtful but caring way darling. It's for your own good honey." I start moving my cock back and forth slowly, holding Amy's hands in mine and pressing my body tightly against hers.

"You've disappointed me many times. You've been naughty too many times, and these are the consequences of your misbehaviour. Aaaaah!! Aaaaah!!"

Amy cries out: "Aaaaah dadddy! Awwwaaaaaaahhh! Aaaaaaaaaaaaaahhh!!"

I pump slowly but more powerfully in and out of your asshole....until.... Aaaaaaaaaaaaaaaahhhhh... spurt...spurt... spurt... my pulsating cock cums heavily and fills Amy's asshole with thick hot semen. 

Despite the pain, Amy looks strangely excited. She and I feel unusually close and connected. She seems to have somehow enjoyed my punishment in a perverse sort of way. I look at her bum and see some of my hot white semen leaking out of her crack, down her leg. I look at her eyes and notice the spark of desire.

"Now darling... tell me the truth, how exactly have you been naughty? What did you do instead of studying? And don't lie! I will know if you try to lie. I am waiting honey."
