Some party, huh? Or, maybe you wouldn't know. You seem to be distracted tonight. Do you like my satin dress? I've seen you checking me out all night. When we were invited to this event, I went straight to the mall to find the perfect outfit to wear for you.

Oh, yes, my dear br*ther-in-law. I wore this just for you! I know how weak satin makes you. And you know how much of an exhibitionist I am. Positioning myself in your eyesight in the effort to pull you away from my s*ster has been such a thrill!

But the fun is only starting. I can tell you're staring to chub up. The bulge is growing in your pants! I still think about those times at your house, when I surprised you with my satin outfits. Those times when I showed off for you while your wife was out of the room. Those times I made you stroke and c*m!

I don't see anyone around at the moment, so quick! Take it out and stroke it for me! I'll help you out by showing you my pink fancy satin panties. That's it. Just focus on the soft, shiny satin. You're so naughty for j*rking off to your s*ster-in-law!

Better hurry before someone catches us!
