It's only three days until I get to babysit--if that's what you want to call it--for Katie, my 17 year-old niece.  Katie's doing her best to get me in the mood for seeing her, and to make sure I'm already under her control before I even arrive.  She just sent me some pictures of her: one set has her in a schoolgirl outift, showing her white panties, and the other set has her completely naked but concealed (mostly) beneath "uncle's blanket".  The e-mail sent with the pictures didn't mince words: "I hope these make your cock hard, Uncle Jack," she wrote.  "And I hope you're ready for a weekend-long stroking session.  DO NOT CUM until you're here and kneeling at my feet...and only if I give you permission."  Katie also mentioned that she could probably invite her friend Samantha over while I'm there; she told me that Samantha has already seduced her own father, and loves dominating older men.  "Bring lots of cash, Uncle Jack," Katie concluded her e-mail; "you know it's so hard for girls our age to cash checks."

What a greedy little cocktease slut Katie is!  I can't wait to see her and to have her force me to beg, crawl, and worship her...for now, I have her pictures to look at, and my cock is harder than it's ever been...
