My dear sister, you know how much I love you. But sometimes, my desires get the better of me. I can't help but fantasize about seeing you with another man. It turns me on so much that I have to touch myself just thinking about it. And when I do, watching your face as you pretend not to notice makes it even hotter. Your moans and pleading eyes drive me wild! Oh, how I wish we could make this happen for real. Just imagine how wet you would get knowing that your big brother was secretly masturbating while he watched you enjoy yourself with someone else. He's such a helpless masochist, always wanting what he can't have. Well, maybe one day we'll find ourselves in that situation together. Until then, let's continue to tease each other like this, shall we? After all, there's nothing quite like the thrill of forbidden pleasure.
