POV, you're my big brother. I'm tidying up while you're at work and accidentally bump something into your computer. I check to make sure I didn't break it, and discover a video open on your computer... a massive compilation of all my best burps. I react in shock as tons of my burps from a plethora of videos ring out from the laptop. I realize that you must be buying my videos... and jerking to them. After listening and reacting for a couple minutes, I pause the video to ponder what I've just encountered. I comment on the quality of the burps in this video, what this all means, and how I'm feeling about it. After a few minutes, I play a few more minutes of the compilation while I continue tidying up. Afterwards, I call you and tell you I have a surprise for you and that I need you to bring some sparkling water over after work. When you get home, I tell you what I found. I am gentle and reassuring about it. It makes sense that you've always encouraged me to become a great burper, and if that's what you're into, I AM the best after all... I suggest that maybe you can release all that pent up horniness by stroking for my burps just this once. I begin burping for you, and you really enjoy it... after a few minutes, I say that if we're gonna do this, we should do it right and take my top off. I just want to be a good sister and give you your all-time fantasy. You cum one more time and I tell you to clean up, and we won't speak about it again.
