Reminds me of when I came home early one day and heard some noises in the master bedroom. I crept down the hall and looked in a saw my wife and sister going at each other. My wife was 40 and my sister was 27 at the time. I immediately got a full hard when they were kissing and sucking tongue together. My wife pulled down sister's panties and I was shocked to see a thick luxurious dark hair covered pussy. My wife pushed her down on the bed and slithered her wet tongue into that hair to find sister's clit. She licked and sucked her clit and pubic hairs till they were drenched with my wife's saliva. After a few minutes, sister grabbed my wife's head and came multiple times into her mouth. I slowly backed away and went to the garage and jacked off shooting a huge wad of cum. Opened the garage door to make noise and give them a chance to get dressed. I never said a thing to either of them.
