Your step-daughter and her husband move in after he loses his job and you notice they fight more than usual now that they stay with you, her step-dad. Your step-daughter keeps going out at night- sometimes all night, in skimpy outfits, and you know exactly what this means. Your step-daughter isnt being a very faithful wife and you decide you want a turn with her as well. You catch her coming in late and threaten to tell her husband unless she fucks you and reluctantly she agrees. The tone changes as she grinds into you and she finds herself enjoying it. As you slide in her she moans "Oh! My step-fathers inside me. My step-daddy is fucking me!" and you let her ride with her tits out until she cums all over your cock. Then you pump her full of cum while she tells you she loves you and youve never been happier to be so wrong, creampieing your step-daughter.
