Update My Sister-in-Laws Story - Enhanced Edition

Description: Recently I met My GF's sister, who is very young and cute as hell. We were at a barbecue and she was sitting next to me, making me nervous because she kept staring at my crotch. Afterward, I brought her home with me for some drinks (and more). It turned into an all-night affair; we drank beer, talked about the stars, and watched My GF's old movies. The night ended with a 3P session in the bedroom, where her tiny little body was perfect for my size. Her pussy felt like velvet, it was so smooth and tight that when she climaxed, her orgasms were so powerful they could knock you off your feet.
