Teasing Little Slut

Was at my sisters yesterday, my niece is taking her exams so wasn't there at the time, however her washing was, all clean, never realised how tits are measured, my niece has a pair of whoppers, I thought they must be 36, 38 maybe. My sis was making me a cuppa, I had a look at the labels 34E, amazing, lots of sexy lacy thongs and panties too.

I nipped to the garden centre for my sister, and that took longer than i expected, when I got back, my Sister was in the kitchen preparing lunch, and my niece was in the living room, pants and bra trying on a prom dress, she saw me but didn't bat an eyelid, pulled the dress over he head, pushed her tits out, put her hand down her back removed her bra, pushed her tits out, ran her hands through her hair, and pouted her lips, "What's think Uncle Dave, Gorgeous or what?!"

she done a twirl stuck her fabulous ass out, and then said "I bet you would? " and then laughed sexily "that's if you haven't already?" then slinked off to see her mum. she was nearly right, I was about to cum in my pants.

Then the little slut teased me all through dinner,
