Humiliating the Homewrecking SIL

Anna is desperate for the sale to go through, she drops by your office with the paper. You are surprised she has the nerve to show her face after what she has just done to her step-sister. She explains if she doesn't get this sale through in the next few days, she is ruined. Watching her desperate and vulnerable makes your cock stir. She also looks incredible her curves popping in all the right place. You grab her by the hair and push her to the ground. She resists by saying she loves her step-sister and it was a mistake before, you take your cock out and she just cant resist. She loves how big you are. You ruin her pretty face with your pre cum and fuck her throat hard. She fingers herself whilst gagging on you. You finish all over her face. She goes to wipe it clean and you wont let her, you like her like this, slutty. She has alot less attitude whilst her face is covered in your seed. She hands you the papers but realises she has forgotten one, you tell her you will sign now, but she needs to go get it dripping in cum. She is desperate and stands up to leave. She comes back and your assistant has arrived for work. You are briefing her and Anna walks in, completely unaware. She is startled and clearly embarrassed. She knows your assistant since collage. Anna awkwardly tries to explain, but your assistant is cruel and tells her she is going to tell. You and your assistant taunt her, telling her she is a slut for cock and she can't love her step-sister that much if she has done this. Your assistant, always secretly wanting to see your cock,asks you to fuck her. Anna is horrified and tries to resist, but with the threat of her whole family being ruined, she lies back and takes you bare. She starts to enjoy it and you tell her to beg your assistant to let her cum. She explodes all over your cock, ashamed. She gets up to leave but you are not done, She begs you not to cum inside her she's not on birth control, it would hurt her step-sister but even has she is saying it, you know she can't give up this cock. She loves it so much.
