[SILFuck]

On Saturday we went drinking me, my wife and my SIL. She was not ready at first but then she got ready.
We all went into our rooms to get ready. I couldn't get time to peek into her room when she was getting ready but when she came out she was super sexy.She was wearing a short skirt which was really tight around her ass and high heels showing off a portion of her things.

So yeah we went to a night club and we drank and we danced.Both my sister and my wife when drinks they drink till they cannot stand.We danced together at floor and when my SIL was unable to move anymore we called a taxi.We had to go down 3 floors as the lift was not working for the taxi.My wife was carrying her sister.But she was also drunk and almost tumbeled at few steps.I told her i will help her sister and she go ahead.She was so thankful to me and started climbing down the stairs in front of us.While i was carrying her sister she was so drunk she almost fall at many places and whenever she will do that i will grab her at some sexy places.That night i grabbed her boobs and her ass,well i enjoyed every bit of her ass.It was damn hot.I had such a hard onn i would have fucked her in the stairways.Every bit of her felt so tight and sexy.I touched almost every part of her body.

So slowly we reached to the car.I put her in back-seat and we drove to home.After reaching home i knew this will be my last chance and i told my wife to go ahead and open the door for us while i carry her sister.She was almost asleep.Then i did some very bold moves.She was in the car not moving.I grabbed her by her thighs and slid her upto me.Because of the friction between her skirt and the seat i could see her yellow thongs she was wearing.Before getting down i slid her skirt back.and then started helping her to the house.On the way whenever my wife will go ahead of us i will touch her at places pretending i am just helping.We finally reached to our house.My wife was very drunk and she went into bathroom and started puking.I took her sister to her room and put her on the bed.She cuddled like a small child but that just made her skirt move up and her bottom was bare naked.I took a huge risk and touched her ass this time her naked ass finally feeling her skin with my hands.I even went ahead and even touched her pussy over the thongs but just slightly.Fearing my wife might come in anytime i just switched off the lights and went out of her room.

I went to my room and saw my wife completely naked.I spread her legs spanked her huge ass to wake her up and then said i want to fuck you.That night i fucked my wife like a wild animal.She was screaming sometimes with lust sometimes with pain but i didn't stop.I fucked her while thinking of her sister and what all has happened.

If anyone can help me.I want to lure my SIL into fucking me.
