Anne & Therese's Sisterly Swap

Anne and Therese Marchais, twins from Montreal, Quebec, love to swap with each other, tricking their boyfriends into sleeping with the "wrong" sister. They really love to share their boyfriends in general, but they have found that some men are too gutless to swing or cheat, so they have found this sexy loophole. Their latest choices are: Orion Tsatskis, a Manhattan businessman, and Harry Llewellyn, a lawyer from Wales. 

Their plan succeeded last night, as Anne led Orion, Therese's guy, into her sister's bedroom, getting him to undress her and give her a bath, loving every sweet moment as he applied the baby oil to her lovely, voluptuous form. After he had massaged her for 30 minutes, she removed his pants to thank him by sucking on his manliness. Then she asked him to take off the rest of his clothes and join her, which he was quite willing to do. She induced him to kiss her whole body from head to toe, then she reciprocated with obvious pleasure. They licked each other in every area of their bodies and did a satisfying 69.

Once the oral delights had been tasted, Anne begged him to fuck her doggy-style like the naughty French (actually French-Canadian) slut-maid that she was indeed. As he pounded her precious pussy, she got him even hotter and harder by suggesting that she wanted him in her awesome arsehole after he finished with her cute cunt. All of this time, Orion never suspected a thing- this was his great girlfriend, whose only flaw (or so he believed) was that she would not share him. 

When she kept her word and spread her cheeks for his hardness, he appreciatively entered her anus, giving it the kind of wonderful, forceful attention it clearly craved. She was so ecstatic about his reaming of her rectum that she blew her cover by screaming her orgasm in a loud-pitched voice, which Therese never did (she grunted during anal sex, but never screamed). Since it was too late to undo his act of "betrayal", and since the girl had given him what he really wanted, he chose to finish the fling instead of withdrawing short of climax. He loosened his load inside her, making her so sweaty she would need to drink bottles of water to rehydrate. 

At this point, he asked Anne the same question that Harry was no doubt asking Therese- "Why?". As for Harry, his experience that night, while different, was no less pleasant, as his "girlfriend" requested that they do a role-playing game. She wanted to be a defendant being sentenced and have him, as the judge, sentence her to do whatever he wanted. He eagerly co-operated with this kinky fantasy, putting on the black robe that she gave him for his role.
Then he ordered her to suffer a "public" flogging with the whip that he liked to bring with him. He hand-cuffed her first, and then he administered the punishment himself (since there was no one else present). She was gagged to keep her from screaming, shouting, or begging for mercy.

After this treatment, he released her to do "public service"- she was to take his cock in all three of her holes in reverse order- ass first, then pussy, and finally mouth. He refused, since this was a penalty, to even lube his dick as he entered her, permitting her only one way to relax herself- masturbation. She gritted her teeth as the painful pleasure took control of her body, shocking her nerve endings into overload. She did not beg him to stop, though, or even talk at all. She wept quietly as the pain part slipped into the absolute relish of a well-filled bottom. 

Soon, she was more than ready for the 2nd phase of her punishment, as he removed his cum-drenched (both his and her cum, of course) cock from her butt and immediately penetrated her pussy. She was so wet, that the penis just eased into her sex automatically, and she felt her whole body shake from the exquisite deliciousness of her cunt being fucked by a cock straight from her butt. She anticipated a grand climax, and she was not disappointed, with his member probing her frontal hole with evident enthusiasm. She soon grunted as she normally did (and would have during the anal part if it had been like the ass-sex to which she was accustomed). That almost gave her away, but Harry was so turned on he failed to notice yet. Then he unloaded, and she quivered from the sheer extent of her excitement as he moved quickly from her pussy to her mouth, making her lick his man-milk, her own cum, and her anal juices from his phallus. He was thoroughly aroused by this last stage, but even so the strange pattern of her grunting caught his ears. Of course, he decided to investigate it after he had dealt with the urgent business of ejaculating into her eager esophagus.

Finally, he determined to know the reason for her grunting, but even as he prepared to ask her, it became plain to him. She was Therese- not Anne; she was the sexy sister, not the luscious lover. He naturally inquired as to the purpose of her deceit, just as his fellow dupe Orion was doing at the very same moment. 

The girls rather happily gave the same answer- "We like men, we love both of you, and there is no greater pleasure for us than to swap and share you, especially if it's without your knowledge. That allows you to swing while thinking you're being monogamous, and it allows each of us to learn what the other knows about her man. It's not cheating if it's mutual, and we all did get some on the side. So. boys, do you want to hold a grudge over a favor we did you, or do you want to hold us as your sex slaves for life, with each of you owning both of us?"

I think that you can guess at their reply to that question!
