A humiliating spanking

I'm ready to go out with some of my girl friends but my boyfriend doesn't like my outift. He thinks my shorts are way too short, he refuses to let me go out in them and he makes me change into another outfit. Even after I have on something he thinks is more appropriate, he won't let me go out until he's spanked me. I'm made to lie across his lap and have my bum spanked. After several swats, he makes me stand up, pull down my trousers below my bum, and then lie across his lap for more. You can see my skin turn pink as he slaps his bare hand against the curve of my bottom and see me grimace as he does it. Several minutes later he has me stand up again and pull down my pretty lace panties so he can spank my completely bare arse. I think I've learned my lesson!
