Custom clip! You've walked into a special satin lingerie store. I am the sales girl helping you find the perfect pair of panties for your girlfriend. Wait, it's not for your girlfriend? Who is it for then? Oh my gosh the panties are for you! I have you try on many satin panty styles and comment on how your cock looks in them. I assure you it's only us in the store, but surprise! All of the other sales girls are here and watching you too. Having all of these eyes on you makes you so hard in the satin. Why don't you stroke with the satin panties? Here, I'll show you. I'll even strip out of my satin panties and have you stroke with those. Doesn't it feel amazing having the super soft satin on your cock?
