You arrive home and realize your stepson is supposed to be sketching a live model for his big projects final grade. You can hear the disappointment in his voice as he tells you she never showed and it was too late to get a replacement. Being the loving Stepmom you are you can't let him get cheated on this grade and offer to pose for him yourself, nude. He is hesitant at first but it's really the only way he can save this semester's grade. Later you come out in your robe, still feeling a bit shy about opening it, but you know it has to be done, so you lay back and expose your breasts, with no panties, but keeping your legs together so as not to expose your motherly parts too much to him. As you watch him paint you feel slightly aroused, as he makes each stroke, detailing your body, you feel a warmth towards him that you have never felt before. He comes closer to re position your arm to support your breast more and lightly touches it, somewhat startling you, but not near as startling as when you notice the giant bulge in his shorts! You can't help but stare and when he realizes you have seen it he tries to cover himself in embarrassment. But you are a good stepmom, and you tell him that a model needs to help the artist no matter what it takes to help him fully realize his artistry. You slowly kneel before him and pull his shorts down. You pull his cock into your mouth as quickly as it comes out and lustfully lick and suck it. He is overwhelmed with lust and asks for you to bend over and take his cock in your pussy, you quickly agree, and feel unimaginable t**** sensation from him entering you, cumming in mere seconds! He continues to pound away at your pussy bringing you to another orgasm until he can take no more. You want his cum in your mouth so bad, wanting every drop to cover your tongue. He has an incredible orgasm in your mouth and you swallow every last drop, making sure to wipe your mouth to recover any that you may have missed, it is so wonderful tasting to you in this heightened sexual state. He asks you to never tell his father, even if you divorce him and you swear not to. Maybe you will do this again he asks, and of course you will you tell him....Mandy Flores
