Sister In Law

My sister in law enma is 4'7 long blonde hair slim with a nice butt at first she was a little flirty then after they got married she started to flash me she would sit across from me and spread her legs knowing i would look and one time she called me into her bedroom and i walked in and she was bent over with nothing on I walked back out of the room a little embarrassed and an hour or so later she messaged me because my brother was home a time and hotel for the following day i did go to the hotel room to find her waiting and we ended up fucking that afternoon up against the window in full view she's a filthy bitch and i remembered her saying in front of the family that my brother has been trying to fuck her in her ass and i talked her into letting me and never heard anyone scream like she does when taking a pounding in the backdoor it's twice a week and she gets dressed and goes back to my brother like nothing has happened
