HIGH DEFINITION VERSION. See full version for a Sneak Peak preview. Part one of MILF1548. Rachel and Stacie were MILF sisters. Each had a grown step-son - Brian and Ricky. One summer the four of them went for a month long vacation on a remote tropic island where they had the run of a luxury condo. Also in attendance was Rachel's husband, Frank. Sadly, however, Frank had to go back to the US almost as soon as he arrived. As the head of large corporation he was often called away on important business. Such was the case now. Rachel was none too pleased to see him go. It was a reminder of Frank's workaholic nature and the fact that he so often put his job before her. Their marriage had been void of romance for a long time, and Rachel had been hoping to restore some of it while they were on the island. She wanted to find a place so remote that he would be focus on family and forget work for awhile. There was something unnatural about this distant island. There were myths of a long forgotten race of people who once inhabited this island. It was said that they practiced strange sexual rituals and that on certain nights you could hear the cries of passion on the wind. So much for that. Yet things were not much better for her step-sister. Stacie was a divorcee who had not been with a man in several years. Since both siblings were immensely horny, their sex-starved status was almost impossible to endure. But, as it happened, there was relief at near hand - in a highly forbidden form. It began one hot morning when Rachel and Stacie were bathing beside the pool and their step-son's were playing around close by. On glancing the young men's bodies - bared, toned, and glistening in the light - the two step-sister's become aware for the first time of what hunky specimens they were. They shared excited comments about them under their breath, and each secretly experienced a taboo moistening in their pussies - for step-son and nephew alike. A seed of lust was sown in that moment. It was a only a matter of time before it grew and overwhelmed them. By midday, the quartet had already started flirting with one another. Numerous beers and wines helped things speedily in that direction. Sat as they were in the downstairs the living-room, there was much hugging and mischievous teasing between them. That night, dressed in only her nightie and robe, Stacie lost her sense of direction while looking for her room. When she walked in on her nephew Brian getting ready for bed, she apologized and made as to leave. But then she saw that he was rubbing his leg. Apparently he had pulled a muscle in his thigh. Stacie remembered how he had given her a sensual shoulder-massage earlier in the day. Now she felt she should return the favor to him. Soon Brian was led face down on the bed and Stacie was running her hands down his back and legs. Both she and her nephew grew increasingly excited by this intimate contact. In time Stacie's robe fell open to reveal her low-cut nightie and her huge, swelling cleavage. Growing hotter, unable to keep the robe tied together, Stacie eventually took the whole thing off. As Brian turned on to his back and got an eyeful of his voluptuous, sexy aunt, he instinctively reached up and began stroking her shoulders. It was enough to push both of them over the edge. In an instant aunt and nephew were openly touching each other in a sexual way. Then Stacie pulled Brian's cock from his shorts and stroked it hard.
