My Ex Sister In Law
 

I did my Ex-Sister In Law many years ago. The first time she was visiting me and my wife and we got stoned and started fooling around before I knew it we were all naked on the bed both of them sucking my cock till I grabbed her and started fucking her while my wife watched. When I saw her several months later I ask her to go for a drive with me as my brother and my wife were gone somewhere. We started driving and I started felling her up so she moved next to me and when I reached for her pussy she told me that she was on her period but she would suck me if I wanted? Yes I wanted her to so she started sucking on me till I pulled the truck over and she kept sucking my cock till I told her I was going to cum. She shocked me by sucking me deeper till I filled her mouth then I watched he swallow my cum. I never knew if she told anyone and this is the first time I have!

That's HOT
 

Hot story. Thanks for sharing. The thought of sisters giving a blowjob together is a big turn on for me. Maybe one day...
