"Well, we have these friends, a couple, that we,,, sometimes,,, well,, we share evenings with each other. We are very close, if you know what I mean?" Sandy manages to get this out with out mentioning anything specific.
"Oh." Candy says, shooting a sideways glance at Derek, who was just as uncomfortable as Candy was at that moment.
Sandy continued, "We just thought that we could all just get acquainted first, you know before we get too serious."
"I see," Candy says demurely, visibly disappointed.
The rest of the trip was quiet and subdued.
When Ben came home Candy and Derek were refreshed and just coming in from the beach with Sandy. Their mood was distinctly reserved and Ben could sense something was amiss. Ben got Sandy alone and she explained that she had spilled the beans about Al and Carla. Ben was much more circumspect about it, "Why don't we let Al and Carla decide if they want to take a rain check or include our guests in the activities?"
"You're brilliant, Ben. Why didn't I think of that?" Sandy admits, laughing.

Al and Carla arrived and were greeted by Sandy, ushered into the living room and introduced to Derek and Candy. Ben was excited about all the possibilities that presented themselves. Al and Carla were initially concerned about the last minute change of plans, but warmed to the occasion as Ben explained their new friend's proclivities. "We'll play it by ear," they had agreed, "no promises, no demands."
Everyone became comfortable with one another and the couples were enjoying the atmosphere when Candy made a comment to Sandy that she had desperately wanted to get back in bed with Ben. Every one had heard the comment and a hush fell upon the room. A tense quiet hovered ominously around the group, finally, Candy looked around the room and asked, "What did I say?"
Carla laughed first, and then everyone erupted into a boisterous cacophony of laughter and giggling. Releasing the tension which had built up over the expectation of what everyone hoped might happen if all went well.
Candy had been watching Ben all night. Derek had watched both Candy and Sandy, his emotions swirled in his mind like a cauldron of festering rage. Al was smitten with Candy, and a change of partners was due and she represented a very positive development indeed. Carla was wondering if she was going to be with Ben or maybe Derek, he didn't seem very interested in her, she thought. Sandy was conflicted, she was happy with any of the men, but she felt herself wanting Ben more, and now she was thinking of ways to be with him while the others were occupied with each other.
Al made the first move; winking at Carla, he moved to Candy's side and began charming her as he carefully touched her in a sensuous manner. Candy responded and was eating up the attention he lavished on her.
Carla realized that as Ben's sister, Sandy, had to go with Derek that left Ben for her. She slunk over to his lap and began acting sluttish, hoping it would further break down the group's reluctance.
Derek smiled as Sandy plopped down next to him and nuzzled his neck as he watched the others in the room making out.
The lights were dim and the couples were in their own worlds, consumed by the sexual electricity in the air. No one moved from the living room, it seemed as though all had agreed to be communal tonight, while they had not agreed in actuality, they did seem to feel it was the thing to do without really thinking. As the petting turned to foreplay, Carla peeled Ben's penis from his pants, which were now open and pulled to his thighs, and pumped it as she kneaded his ball sack. Carla seemed to be in the lead tonight, and relished her opportunity to show off her prize prick to the other girls. "Yumm," she said heavily, "I love this big meat."
Sandy managed a sideways glance as she was prying Derek's pants down, thinking as she did so that it should be her with Ben, later maybe, later. Candy too had been compelled to look, she desperately wanted Ben again, she meant to have him, and maybe she could manage to be with him later she thought.

Derek had almost forgotten his enmity while Sandy administered to him sexually, then, watching the girls all look to Ben's impressive tool with lust filled eyes, he remembered the hurt and rage, and his fire was rekindled. Then suddenly, Derek, very agitated, stripped Sandy of her remaining clothing, manhandling her back onto the couch and he then moved down beside her, and began caressing her breasts, and then stroking her abdomen and her thighs, finally stroking between her legs, Sandy was at first scared at this rough treatment, and then resisting, her body began responding to his caresses.
He continued roughly stroking her, now her inner thighs to her cunt, her body jerking when she felt his touch there, whimpering now as his fingers took possession of her cunt, invading the moist lips. She turned her head away when he tried to kiss her, refusing to surrender her lips. However, he continued his expert stroking of her breasts and the now moist red lips of her cunt, Sandy, gasping as he found her clitoris, caressing her until she was groaning. He was steadily overcoming her resistance and her obvious intention of not responding to him.
The others were unaware of Derek's strange behavior, and Sandy remained quiet, except to resist his rough treatment. He continued his caresses, his stroking of her body, gradually pushing her legs and thighs open more, her cunt pulling open, Sandy was trembling, whimpering now, her body flushed as against her will she was responding to him. Soon it was clear that she was helpless, her legs spreading fully to his pressure against her thighs. She finally surrendered, her arms falling to her sides. The picture that she was presenting was incredibly erotic, her firm breasts, her legs and thighs spread, her wet cunt opening, compliant now, moaning as he stroked her.
Derek felt her surrender, relishing her helplessness now, as he prepared to mount her. He lifted her legs and thighs, so that the others had a clear view as he rose up, mounting her and directing his cock against the wet swollen lips of her cunt. They could see as he moved his cock up and down the lips of her cunt, moistening the large purple head of his cock. Then he positioned his cock at her entrance and began to push with a steady pressure as Sandy's whimpers changing to groaning as she felt herself beginning to stretch to accommodate his entrance into her defenseless cunt.
He continued the relentless pressure, stretching her more till finally, with a hoarse cry from Sandy, the head of his cock entered her. Slowly he began to push further into her, and the others could now see her cunt stretched tightly around his cock, Derek moving in and out with short strokes, wetting his cock as he continued to penetrate her deeper with each stroke, Sandy, wide eyed and moaning with this invasion. Then finally, with one last thrust, he impaled her on his cock. Then Sandy cried out and her body began jerking, and her lovely legs clamped over his thighs as her trembling body erupted in a powerful orgasm, which took her completely by surprise, she had never been treated so rough, and worried that she had come during the violent treatment.
Candy watched her boyfriend as he responded to Sandy in this manner. She was instantly moved to show Al that she too was capable of passionate love making.
Gradually Sandy relaxed, and at that point Derek began a slow deep thrusting into her, his cock shiny with her juices, pulling back each time till the head of his cock was at the entrance of her cunt. He took a long time with her, but finally he began to increase the speed of his thrusts, Sandy jerking with each thrust as now her body began to respond. She was flushed, trembling and groaning, as Derek moved her closer and closer to another climax. Finally, with a shrill cry, her orgasm was upon her-crying out again and again as her legs clamped over his thighs, her body jerking, her arms gripping his back. At that moment, Derek's own climax began, groaning, he erupted into her, gripping her ass as he fully impaled her, spurting into Sandy's belly, draining his cock into her.
Carla gripped Ben's arm, her eyes wide with excitement. Well, she said, "How did you like seeing your sister get thoroughly fucked? She really seemed to enjoy it."
Finally it was over, and Sandy could not believe the way she had responded to his brutal fucking. She was tearful, now lying spread-eagled, her cunt gaping open, their mutual juices visible to all.
