Mellow Kitty Shorts, part 2 (Mf, inc, mast, no sex, panty fetish?) by this guy (thisguy.1066@gmail.com) Summary: A horny guy serves as a nanny for his very attractive thirteen year old niece. One particular piece of her clothing makes a great cum rag... RAINY DAY NUMBER 1 Sarah walked into the kitchen this morning for breakfast at a few minutes before ten o'clock. I wasn't all that surprised to see that she was wearing one of the sleeveless t-shirts she usually wears to bed: the outlines of her nipples were just barely visible through the shirt's thin cotton fabric. Seeing that made my dick twitch in my pants, but ultimately that wasn't what I cared about. Glancing down her body, ostensibly to see if she was wearing shoes (for some reason her father doesn't like it when she goes bare foot), I spied a small creamy stain about the size of a penny on the crotch of the pink Mellow Kitty shorts which (if my arithmetic was correct) she had been wearing for nearly seventeen consecutive hours. At that very sight, my dick went from a little firmer than its normal flaccid state to about three-quarters hard. My eyes continued down Sarah's bare legs. As I had expected, she wasn't wearing any shoes. "Sarah, go put some shoes on," I told her. "But Uncle Burt, I'm not gonna go outside," she half pouted, half whined. "I know, but if you step on something and hurt your foot your dad will kill me," I reminded her for the umpteenth time. "Since you're already here, eat your breakfast first," I added pointing at the table. As usual Sarah ate, then wandered off. "Put some shoes on," I reminded my thirteen year old niece "Do I have to?" Sarah practically whined. "Yes," I said flatly, going through the same conversation we have two or three mornings every week. "Okay Uncle Burt..." she trailed off. I didn't see Sarah again for a good half hour. When she did re-emerge from her bedroom she was wearing a pair of dress shoes she had outgrown about two years ago. It drove me nuts, but she'd gotten into the habit squeezing her feet into a pair of shoes that were way too small for her about once a month. Then, about two hours later, almost on queue; Sarah whined to me, "My feet hurt, Uncle Burt: can I take off my shoes?" "It always happens when you put on shoes that are too small for you," I reminded her as I went about vacuuming the living room. "But Uncle Burt they really hurt," she whined. I turned off the vacuum and said, "Well, you can change into shoes that fit if you want to." "Fine!" she growled before storming off to her bedroom. *** Several more hours passed before I saw her again, this time for dinner. She was still wearing the same sleeveless t-shirt she had been wearing at breakfast. She still had the same too small shoes on from earlier in the day; although I'm all but certain she took them off when she went into her bedroom and only put them back on before coming to dinner. And yes, she was still wearing the pink Mellow Kitty shorts. As Sarah sat down at the table, out of the corner of my eye, I noticed that the small creamy stain on the crotch of the pink Mellow Kitty shorts was nearly the size of a nickel. The creamy stain had grown nicely over the past several hours... *** After dinner, Sarah went into the living room to watch an old movie that was being broadcast on TV. Like always when she watches TV, Sarah sat down and pulled her knees up to her chest. With her knees against her chest like that the crotch of her pink Mellow Kitty shorts was on full display. When I walked into the living room and saw her sitting like that, with the creamy white stain on the crotch of her pink Mellow Kitty shorts staring right at me, my dick went from almost completely soft to fully erect and hard as rock in a split second. I quickly sat in the chair on the far side of the room. From there I was able to watch the TV and surreptitiously glance at the creamy white stain on the crotch of Sarah's pink Mellow Kitty shorts for the remainder of the evening.
