PeeMan
Your girlfriend is my slut. I have a nickname for her: MLC. I'd make sure I called her that around her girlfriends. If they asked what it meant, our shared g/f would have to tell her friends, "It means 'My Little Cunt'. I'm here for his pleasure." If she messed up 1 word, she'd have to bend over in the little skirt she'd be wearing w/ no panties, and I'd spank her right in public in front of all of her friends. We'd be quick about, then pretend like nothing happened. Every once in a while I'd pinch her nipples through her shirt hard enough that she yelps. I'd also stick a finger in her pussy and in her ass, which she would keep lubed & clean for me at all times. When I was done, I'd bring my finger to her mouth for her to clean. Whenever I get horny, I'd just interrupt what she's doing to get a blowjob from her. I see that you already have her well trained in wearing skirts with no panties, and in being tied up for our pleasure. Well done, PeeMan. She will indeed lay on a beach completely nude for complete strangers to see. We will talk to her and tell her what a slut she is an how hot she should be. She will do this because we ask her to.
