Punishment from my master

[JustAnotherSlave:p]

My master was highly disappointed with my performance last night.
This was my punishment:

He ordered me to strip down to my panties as soon as I got home from school.
I did as I was told, and got on my knees, stripped down to my panties. I then presented my ass and my cock as he ordered me to. Then the punishment began:

It started with a couple spanks on my butt. It wasn't too intense, but it left my butt kinda sore and slightly red. I then penetrated myself with my dildo. While I was riding my dildo, I was ordered to edge myself until he was satisfied. I edged four times, before I was allowed to cum. Then I had to cum again.
It took multiple orgasms, and my cock was extremely sore. I finally came after orgasming four times. My master was merciful and let me take out the dildo and rest.

How I feel after it:
My cock is still extremely sore from edging so much and my ass is sore and loose. I wish I was spanked a bit more, but I'm glad I satisfied my master and was punished for being a bad slut.

I will tell any future punishment ideas you guys come up with to my master.
