I've been insatiably horny with no one to fuck me and I've been venting about it so much to my housemate by marriage, Sophie, that she's grown annoyed by it. This time though, I start whining about how horny I am and she actually offers to help me out! At first we question it, we ARE step-sisters after all, it's a little weird! But then I am pleasantly surprised to learn she has a cock! I get fucked by my step-sister in various positions, enjoying her cock and the scent of her hairy armpits.
