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 forced to 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 sisters 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, stroked it hard, and commenced to suck upon it ravenously. Neither of the lust-crazed pair felt any hesitance or shame about what they were doing. They were committing a taboo act, and perfectly okay with it. In due time, after her long oral-pleasing of Brian, Stacie knelt near to him so that he could finger her exposed pussy while she jerked him off. Her nightie had fallen loose by now, and she used her free hand to play hornily with her big breasts. After all this foreplay, Stacie got down on her hands and knees and begged her young nephew to fuck her deep and hard from behind. Brian gladly went at it. He pounded his big cock into Stacie's pussy until she cried out at the top of her voice. Such was the force of his thrusting that Stacie's whole body shook from the impact. There was equal passion when Stacie later got on top of her nephew and rode him long and hard in the cowgirl and reverse-cowgirl positions. This was her first night of fucking in far too long, and she made up for it by working herself up and down the young man's cock with a tireless frenzy. Come the end of it, she was a panting, thoroughly satisfied MILF. Meanwhile, Rachel and Ricky were having a private aunt-nephew meeting of their own. Rachel had originally come to his room to say goodnight. But events took a different, hotter course to their shared lust for each other. When Rachel drew close to the young man, he turned around, grabbed her, pushed her to the wall, and started kissing her hotly. Rachel acted shocked for propriety’s sake. Then she gave up herself to pleasure. She had been wearing a short skirt and a tight lace top. These came off very quickly under her finished eager hands. With her big breasts uncovered and her panties disposed of, she lay back on the bed, parted her legs, and welcomed her nephew moving down to kiss inside her thighs and then tongue her wet, needful pussy. The young man enjoyed a long feast, and then moved up to fondle her breasts and suckle upon her nipples. Afterwards, Rachel took over. Having sucked her nephew cock big and hard, she climbed on top of it and happily fucked herself up and down on it. This went on for some time - until Rachel switched things to the missionary position. Here Rachel moaned and cooed under a deep, hard pounding. She and Ricky were so horny that they continued to go at it spoon-style. Indeed, Ricky got so carried away that she ended up blowing all his young seed deep into his aunt hot, tight and fertile pussy. Rachel gasped as she took it all. She was not on the pill or any other protection. There was a real chance she might have been knocked up by her nephew. Yet she was not all that concerned. She saw something amusingly wicked and kinky in such a possibility. As with her step-sister and her step-son, she and Ricky felt a distinct lack of guilt about what they had done. Three weeks later, on another lovely morning, Rachel and Stacie were sitting out in the fresh air, enjoying a heart to heart talk. Each of them acknowledged how healthy and happy the other had come to look of late. During the course of the conversation, Rachel even told Stacie about her nights of passion with Ricky. Many more had taken place since the first one. The same was true for Stacie and Brian. And so confession was met with confession. Each step-sister had striven to hide their forbidden conduct from the other in the belief that it wouldn't be understood. But such concern had been unfounded. The siblings actually understood and sympathized with the other's actions completely. They both felt that something great had come from their time with their nephews. What troubled them was that they would be leaving the island in a couple of days. It did not seem possible that their taboo relationship could continue in the outside world - with the likes of Frank around to catch them. Therefore, sadly and reluctantly, Rachel and Stacie agreed to tell young men that all the recent forbidden sexual fun would have to come to an end. Brian and Ricky were surprised to find out that they had each been with the other's step-mom. But there were no hard feelings between them. They felt only regret that their wonderful sexy adventure was coming to a close. However, Rachel and Stacie had something up their sleeve to soften the blow. They were determined that the four of them should finish things off with a bang. It would be one last tremendous fuck involving them all on the hotel's king-size bed that night. Everybody loved the idea and could not wait for the time to come. When it did, there was no holding back. Things began with Rachel and Stacie busily stroking and sucking their nephew's cocks as at the same time. The young men leaned back groaning and smiling from the incredibly skilful pleasuring that they received. The older women were dressed in just their nighties - looking as sexy and comely as ever. On the heels of the long and intense warm-up activity, there came a torrid spell of fucking. Both aunt-nephew couples went at it hard and wild in the cowgirl, then doggy-, then missionary positions. Rachel and Stacie moaned and cried in delight as they welcomed thrust after thrust of their nephew’s big cocks into their hungry pussies. Then, after Rachel had finished a sixty-nine with Ricky, she and her step-sister did the most taboo thing of all. In their crazed horniness, they each started jerking and sucking off their own sons. They could not help themselves. Deeply and lovingly they licked and worked their lips back and forth along their young men’s hard shafts. Brian came first. He blew all his hot load over his step-mother’s hands and his own stomach. Nearby, Stacie pumped her step-son’s cock for all she worth. Rachel came and urged the couple on - straddling Ricky’s face so that he could lick her pussy out in the process. Finally, the young man unleashed all his pent up man-juice. Stacie kept her lips sealed around his cock the whole time. His every drop shot down her throat, and she ended up swallowing it all. Afterwards, she knelt in a daze, hardly able to believe what she had just done. Then Rachel came over and put and around her, smiling. She said there was nothing to feel guilty about. The sex had been worth it. The greatest thing they had ever experienced. Stacie nodded, smiled, and licked a last bit of her step-son’s cum that hung on her lips. Rachel leaned in and French-kissed her step-sister to share to share the taste of it express her own sibling-love. Never would any of the taboo-breaking foursome forget their wonderful time in paradise.
