JOI Femdom Tease with Cotton Panties

I tease you tremendously while I'm wearing a flirty black dress. I know you're crazy about my fullback cotton panties, and I give you tiny glimpses here and there. Here are the rules, when you see my panties, you can stroke. When you see them close up in your face, you can stroke fast, but when they are at a distance, you have to go slow. See if you can last until the very end, when I give you the magic words you should need to cum as a well trained slave boy!
