My sister in law...

Often when my partner invites her sister around the house, I never kick up a fuss.... always give it a good smile. She turned up wearing some tight leggings which were a bit see through revealing a nice black thong, I eyed her up and down, and I think she noticed, but couldnt look for to long, she came in, and we all started to have a few drinks.

My partner went to bed as up early the next day, and me and her sister stayed up, we carried on drinking and both getting worse for wear, she spilt a bit of her drink down her top, and I got a towel and dabbed it down for her, she then made a move on me, at first I resisted..... but then I couldnt hold back, we snogged passionately on the sofa as my hand slipped up her top and carressed her boobs, and removed her shirt and bra, and sucked her hard nipples.... we had to be quiet and careful incase her sister heard. My hand slipped down her leggings and I felt how tight and wet she was, I slid a finger in, and she was getting wetter and wetter, I sat back and got my now really hard cock out, she said she had never sucked something that big. She spat all over it, and licked it up and down, it was just getting harder and harder!

She then jumped off me, and bent over on the sofa, and I pulled her leggings down, and just had to lick her out a bit, I slid my tongue down her lips and delved straight in her tight hole.... getting every last drop out, I knew she was ready for a really good hard fuck then, I forced it deep inside her, and pounded her pussy hard.... she was screaming into the cushion, I slid a finger in her ass and she was enjoying it more and more, we both wanted to cum together.... I got her on a front, and cummed all over her face, making her lick it up.... it was the best!

She then went to bed, and the next morning, we both smiled at eachother, and went out seperate ways....
