My owner challenged me and I failed so I had to post my apology

I was being teased by my owner and I kept getting closer to edging every time I had to circle my clit 80 circles per minute with the help of a metronome so he tasked me with lasting 5 minutes while circling without having to stop because I'm not allowed to edge. He said I had to post my apology here if I failed so you already know the outcome. I kept wanting more pleasure and I foolishly accepted. I ended up having to stop because I can't edge and ended up being 15 seconds short of the challenge ;-;. I don't deserve to orgasm and I'm too pathetic to get to edge. I don't deserve the pleasure and I'm sorry I thought I could handle that amount of pressure on my clit. I don't deserve it until I can control my owned cunt better ><. I have been denied for twelve days and I need more training from Sir before I'm allowed or even deserve anything better.
