Sister-in-Law = Little Nymph

As i’ve mentioned before, my girlfriend’s little sister is quite the looker. she’s a typical highschooler, 5’3”, 110lbs, jet black hair over a pretty face, with a tight little body and long lean legs with bcup breasts. other than spying on her changing, she comes across as innocent and naive. im sure many guys have encountered this type of girl, shy, demure….and kinda stupid. i found out that she does stupid things, how stupid, i wasn’t totally sure at first, but when the whole mystery unravelled, i was shocked, but used it to my advantage.

at my gf house there’s 3 computers and my gf and her little sister share the older one mainly for homework and netsurfing. one day when no one was home, i was using that computer to do my online courses when i came across a folder named “personal stuff”. i thought it was my gf’s so i opened it up and found out that it was full of pictures, video clips and journal entries….of her little sister.

curiousity killed the cat so i decided to preview the pics quickly to see what was on them. HOLY SHIT! i could see that they were all pictures of her and her friends at parties doing naughty things like drugs and sexual situations. i immediately started to open the files to take a closer look. drinking, smoking, drugs, topless, makeouts, groupsex…it was all there, this little girl was going wild when she was at parties! there she was with her girlfriends and guys going buckwild; in one picture she was leaning naked over one guy but nothing more, although her friend had a guys cock in her mouth and smiling! i needed more, so i opened up the video files. i found what i was looking for. it looked like 3 different occasions, but in each video she was having sex with different guys. i think her and her friends go to these parties and get fucked up while getting fucked up. on one of the nastier tapes, i found her getting gangbanged by 3 guys; they were running a train on her, filling her with cock and she just smiled for the camera…dirty slut!!! i could hardly contain myself, i watched the video on loop and started jerking off. typical highschool guys, they were banging like jackhammers. they could barely hold their load and each one started spewing jizz all over her chest and stomach.
