See full version for a Sneak Peak preview. Part one of MILF1585. Rachel and her twin step-sister Robin are physically identical, but morally opposite. While the former is as chaste and honest as an angel, the latter is as promiscuous and devious as a devil. Despite such vast differences in personality, the two siblings live in the same house. There is constant antagonism between them as Rachel tries to reform Robin, and Robin tries to corrupt Rachel. And now comes an event that is going to strain their relationship even further. For sixteen years Rachel has been the loyal and trusted assistant of a devoutly religious dentist named Dr. McDinton. Dr. McDinton is going abroad for three weeks to do charity work on behalf of his church. Because of his high opinion of Rachel, he has asked her to take care of his step-son and step-daughter, Kyle and Jayden. The pair are old enough to be left by themselves, but Dr. McDinton is reluctant to allow them such liberty. The previous year, unsupervised during his absence, they had done a number of reckless things - including getting tattoos and watching pornography. He does not wish a repeat of that. For her own part, Rachel is flattered at the faith her boss is showing in her. She promises to watch over the pair and be on her guard against any hint of sinful activity. Being a person of equal piety and reserve, she completely understands Dr. McDinton's concerns. However, fearing that her step-sister Robin will have a bad influence on Kyle and Jayden, she gives her a stern lecture in advance. Rachel has been given a big responsibility by her boss. She does not want Robin messing thing up for her - or warping Kyle and Jayden. She wants to see her wear appropriate clothing for once, and she wants her to watch her language. Robin spends more time mocking her step-sister than listening to her. She has no intention of moderating her behavior. Indeed, the more trouble she can cause, the better. It does not take her long to get started. With Dr. McDinton barely having departed on his travels, Robin decides to check out her newly arrived guests while her step-sister is absent. As her luck should have it, she spies Kyle taking a shower. He is a fit, handsome young man with a big cock that greatly excites Robin. Remaining out of his sight, she leans back against the wall, braces her legs apart, and begins to play with her hot, wet pussy. Hers is a wanton image - a busty, curly-tressed, scantily-clad, grinning, lip-licking, horned-up vixen. Having brought herself off, she celebrates by sucking her own tasty juices from her fingers. Meanwhile, Jayden is in her room, lying back on a couch, panties pulled aside, legs spread, blissfully strumming her naked pussy while looking through pornographic pictures on her phone. She thinks she has some privacy, but she has failed to reckon on Robin making the rounds. Passing by the open door, the wicked twin gets an eyeful of what's going on, and decides to hang around and see how it plays out. Soon her pussy is wet and hungry all over again. By the time this second show is over, Robin finds that Kyle has finished his shower, gotten dressed, and retired to his room. What follows is a whirlwind seduction by Robin. The mere sight of her approaching in a tight red dress gets the young man aroused. Before he knows it, she is all over him, urging him to embrace his wild side. Kyle is helplessly carried along. Robin kisses him, runs her hands all over his body, rubs her stocking-clad legs against him, smothers him with her breasts, straddles him, pulls her big breasts out of her bra and urges tells to suck on her nipples while she energetically dry-humps him. Kyle's eyes almost pop out of his head. He has fantasized about sex for a long time, but never come close to having it. Now he gives himself up to The Robin Experience. He accepts her invitation to feast on her breasts, and later winds up licking out her pussy. Suddenly, however, he hears his step-mother calling and gets cold feet and backs off. Everything has happened too fast for him. Robin is disappointed, but she decides to not to pressure Kyle for the time being. She knows she will have him sooner or later.
