Yesterday to my surprise I caught my gorgeous wife and my knock-out step-daughter having sex in our guest house. They were all naked, big perky tits out and sharing a double sided dildo. My wife panicked, my daughter just smiled and giggled. My wife in a panic that she had just been busted, with our daughter suggested that my daughter and I have fun too. She ask her if she would be alright with that. My daughter was nervous, shy and hesitant... then told her mom yes I guess so, it would only be fair. So I fucked my daughters brains at with my wife there and cummed inside her and let my wife eat it out of her pussy. Oh my wife felt/feels bad about not telling me etc etc but little does she know I have been having sex with my step daughter for a long time coming.
