My 2 sisters

I've got 2 sisters..older, early-mid 50s. Half-sibs, we have diff dads. Both attractive brunette, busty, curvy. One is religious (known as "good sis") but was wild in her day and still gives off hints or a semi-lewd joke here n there. Other is in a sexless marriage and cheats. ("Bad sis") (With my help..will expound more on that another day..no I dont fuck her..I just help her set up playdates on the side lol) We talk very openly about sex even swap stories n porn.

I have heard bad sis getting fucked several times now. I love it. Good sis, well. I heard her a lot when I was real young Now she would never, supposedly her and hubby dont even have sex anymore. But she still loves to wear low cut tops and show plenty of cleavage. A former Friend of hers tells me she thinks its a front and she cheats too. I actually fantasize about her getting fucked a lot now
