I've been reading this site for a couple of months now, it always turns me on.
My story takes place about three or four years ago, when I was 11 or 12. I had a niece, the same age as me, she has brown hair and green eyes. We'll call her N. N was always flirty with me, one day when we were playing hide and go seek, with her and her brother, she hid in the shower with her brother, and when I opened the curtain, she had her hand under her pussy, like grabbing it (she was wearing clothes). She looked at me and giggled and quickly took it off.
Then one day at her house she was laying on a couch next to me, and she began to stare at me, like right in my eyes. I tried not to look, but I could see her out of the corner of my eye, intensely staring. I looked at her for a few minutes, she was smiling a very flirty smile at me, looking into my eyes. I have to say after a couple of minutes I was very hard. I smiled back at her and she blushed and put her head into a pillow. We continued to look at each other, me now very horny and blushing intensely, and her blushing too.
Then my sis and her mom told her to pick up stuff off the table, and as she was doing this she was doing this sexy move, moving her butt slowly and sensually on and off the couch, she did it until she was right next to me and then I thought she was going to do it, you know put her ass on my cock, but just as she was about to come on me, she flashed me a very sexy smile. Then as she went into the kitchen to throw something out, she rubbed her butt sexily and blushed and giggled (her mom couldn't see her, no one was in the kitchen).
When I went home I jacked off a lot to this, and I still do to this day. I have had an attraction to this niece for a while, she is very pretty and I wouldn't mind her hand on my dick. but the feelings mutual. Once when we were 12 or 13, she woke me up to ask me to lick her boobs, which I did, and I caressed them and sucked her nipples.
