My Stepmom is a Suckslut for all of my Friends

It started with one, but now they're all using her mouth! My four best friends are treating my step-mom's mouth like their personal jerkoff hole. Every day I come home to find someone feeding her cock. They act like it's the most natural thing in the world, casually commenting on how great her mouth is, what fun it is to push their dicks in her throat, how hot she looks coated in jizz. When I'm not around to witness this debauchery myself, they're sending me photos like it's just what buddies do. I've tried to plead with her, but she tells me to stop whining. Men with hard cocks need a good throat to cum into. I know she's never going to stop.
