Part three of MILF1514. Rodney had come back early from work, heard sounds from his step-mother's room and cautiously gone to investigate. He had seen most of what had taken place - without their ever knowing he was there. Now, some time after Jake had gone out, he went to confront his step-mother about what had taken place. She was tidying her room, covering up the evidence of her recent torrid fuck. She had donned a silky robe, beneath which she wore the sexy lingerie from earlier. All of sudden, Rodney was before - pouring his heart out. He told his step-mother how much her lover - how bothered he had been at seeing her and Jake together - how he wanted himself to be her lover and the true Man of the House. Neither he nor Rachel knew quite how it began, but in instant they had crossed the line of taboo and entered into a long, loving, open-mouthed kiss. They felt no need to question what they were doing. It seemed as if it had been a long time coming, and was somehow right. Presently, they were on the bed together. Rodney opened his step-mother's robe, revealing her naked breasts. He squeezed and fondled and nursed upon them. Then he lowered his face between her spread legs and gave her pussy an expert licking. Rachel moaned appreciatively. She uttered taboo comments to her step-son, and urged him on in his pleasuring. In due time she climbed on top of him and leaned over - smthering him with her dangling breasts and inviting him to suckle on their nipples. Erotically she ground her naked pussy against his cock. Next she treated him to a long cock-sucking that was every bit as wonderful as the one she had given Jake. Then the forbidden step-mother-step-son fucking was underway in earnest. The first position saw Rachel back on top, writhing in delight as she eased her pussy up and down Rodney's hard cock. Much kissing, breast fondling and slamming together of hips accompanied the action. The ensuing doggy-style fuck was even hotter. Rodney pumped his step-mother’s pussy with the special love-passion that only a step-son can possess for a step-mother. He made her gasp and cry out in delight and beg for her cum. This he gave her, thick, copious and creamy - right in her eager mouth. After the amazing of experience of fucking her own step-son, she realized that she did not need Jake as her lover after all. In addition, she thought it best not to have anything to do with him once his stay was over. She felt it would be too awkward. Besides, she had learned of Jake’s cynical side - his wager that he could seduce her. Rachel did not want anyone like as a lover. One evening, about six months later, she and Rodney were sat snuggled together, happily idling the hour away when Jake suddenly called in. Neither she nor her step-son felt particularly pleased to see him. But Jake had not come to inconvenience them. He only wished to collect a DVD he had left behind during his stay. Rachel, remembering where it was, duly made as to get up. Her movement was strained, and Rodney had to assist her. Here Jake saw that she was sporting a big pregnancy bump. He looked very nervous. Rachel saw this and put his mind at ease. Do not worry, she said. It is not yours. With a sly smile she looked at her step-son and rested her head affectionately against his chest.
