You've wound up moving in with your stepsister temporarily and something starts happening between you that you didn't see coming. Well, having to share a bed was inevitably going to bring you both much closer together and you have to admit, you've always struggled to take your eyes off her. But this passionate taboo affair was not on your bingo card for the year. Meanwhile, your stepmom keeps pestering you both to go and visit your stepaunt. You live locally now so there's no excuse! Except your stepsister wants you to make an excuse for her. She refuses to go, reminding you how manipulative your stepaunt can be and that seeing how the two of you act around eachother now could rouse her suspicions. You cannot risk letting this secret slip. Against your stepsister's warning, you visit your stepaunt and true to character she opens the door in a see through robe, leaving none of her voloptuous curves to the imagination. She immediately begins prying into your lovelife before bluntly asking how long you've been fucking your stepsister. You almost spit out your beverage and go to leave, only for her to turn up the charm and begin seducing you. She puts your hands on her tits and before you know it, your cock in her mouth. You're already in one familial affair, what harm is another? She promises: both your secrets are safe with her.
