He began to fuck in and out of her, with long, practiced strokes, sinking his driving prick to the hilt in her willing cavern, withdrawing it almost entirely out of her now warmly contracting pussy, matching thrust for thrust as they bucked and slapped against each other, their dark curling pubic hairs brushing together and entwining. Sandra's hair flung out around her face as she tossed her head from side to side, and tiny mewls of ecstatic pleasure forced themselves from between her grinding teeth. McLean was arousing new sensations in her and her body was responding with a hedonistic answer of its own. It was heavenly, writhing about in pagan delight under the passion-demented body of a man – a man who was depraved with desire for her! The idea that she had aroused him to such a fever pitch thrilled her. Her body had incensed him like this, enflamed him with uncontrollable lust. Her flesh tingled with the wanton abandon of it all, being fucked, and fucking back, for all she was worth. Gone were any lingering thoughts of husband, of Sam… her body was the master now, its desire her only duty to satisfy.
Outside the window, Sam felt that he was going to explode, so intense was the crackling ache in his balls and the urgent call in his cock. His anger had faded to excitement as he continued to watch his mistress going crazy from the fucking the veterinarian, McLean, was giving her. The lewd sight excited him unnaturally; his fury with McLean for tricking him giving way to jealousy as he observed the other man's pumping body, his ecstatic look of pleasure that coated his face, the willing, responsive body of Sandra beneath him. It was all too much for him… he couldn't take it any more…
Sandra was riding the waves of an indescribable joy. Her body was completely in tune with McLean's; they were as one, sliding and twisting and rocking together on the star-studded way to the acme of their desires. Her body was reaching, striving to achieve the unrebukable climax which was building up in her, and which wouldn't be long in coming.
From the back of her mind, Sandra heard a sound which turned her blood to ice. The door was opening, and someone was coming into the room!
Terror flooded through her, paralyzing her responses momentarily, and the icy fingers of fear clutched grotesquely at her heart. Turning her head slightly, she could just see through a chink in the tangle of her and Jeff's bodies, the lower torso of a naked man!
Her eyes widened at the sight of the huge, obese penis which jutted out obscenely from its base, and there was something slightly familiar about it. The stranger was standing stock still, and Sandra blinked her eyes, wondering for a moment, if it wasn't all just a lewd mirage.
When she focused again, she had to bite back a blood-curdling scream. The torso was coming, coming, towards her, the elongated shaft bobbing obscenely. Nightmarish terror threatened to send her hurling into unconsciousness.
Then she felt herself being turned over, to the side, McLean's arms still grasping her tightly, his tireless cock still slicing ceaselessly in and out. Oh, God, she sobbed silently, what is happening. Who is it?
The pounding of bare feet came nearer, and then a coarse, lust-crazed voice rang out: "For Christ's sake, McLean, wait for me!"
It was Sam! Her throat was arid and she wanted to jump up and flee from this ultimate degradation but she was a prisoner of her own body, still responding heedlessly to McLean's insistent hammering. Agonized, she felt the trim smooth ovals of her buttocks being spread apart, heard Sam's excited gasp as the dark little ring of her anus came into view, and then she sobbed aloud as she felt the hard, stubby head of his dancing prick come into direct contact with the tight little hole. What was he going to do to her? her mind pleaded in silence, suddenly terrified by the confrontation with her lover.
The sight of Sandra's round firm buttocks jerking backward enticingly under McLean's frontal thrusts egged Sam on to a new plateau of desire, and with an excited grunt, he pressed his thick forefinger against the crinkled little sphincter, worming it into the tightly resisting little passage until he had intruded as far as the first knuckle.
"… nnnnggghhhhhh…" Sandra groaned as she felt the maddening pain begin in her back passage, and she began to struggle wildly, twisting her ass around in wild staccato attempts to dislodge his firmly imbedded finger. Her feverish flailing seemed to incite McLean to boiling point, as he continued to fuck heedlessly into her ravished vagina.
"That's it… move that ass…" he groaned, seemingly oblivious to the farm hand's entrance.
Sam rotated his finger around inside the tight little rectum, sinking it deeper inside her, until he suddenly pulled it out abruptly with a loud plop! which gave Sandra a momentary feeling of relief.
But it was shortlived, as she felt again the hard, excruciating pressure of Sam's rock-hard prick head against the cringing little anal mouth, and as he continued to jab and pressure the tiny hole, paralyzing realization of what was going to happen washed over her with tumultuous force.
"Oh God, please don't, Sam…" she shrieked at the same time as he lunged forward in a snarling, brutal surge, and forced the vainly resisting muscle to yield under his greater strength.
"aaaaarrrgghhhhhhhhh… No! No! Please stop!" she sobbed as she felt the splitting pain of his brutal anal entry.
"Please stop, Sam… pleeasssseeeee…" she continued to wail as he began to inch forward, forcing open the tender internal membrane with his merciless onslaught.
"Oh God, it hurts! It hurts too much!" the demented woman implored her lover, but to no avail. By dint of pure strength, Sam managed to slide forward until the full length of his lust-driven cock was imbedded in her back passage. Her whole backside was a sheet of raw fiery pain which pushed unmercifully up the length of her spinal column, culminating in a shattering pain in her brain, which was actually the force of the knowledge of the utter degradation the two men were subjecting her to. She was like helpless chattel between the two of them, a mindless being existing only for their pleasure, as they double fucked her, one in front and one in back and filled the air with their animalistic groans of pleasure.
Sam began to screw slowly in and out of her throbbing rectum, and she shamefully remembered the similar assault by her husband, which had been fading into a bitter memory, and was now recalled with new venom. Then, slowly but surely, the soft rubbery walls of her back passage were beginning to widen, thus mercifully lessening the incredible pain. When the agonizing pain had finally cleared, Sandra was sorry it did, because it revealed something which added more shame and humiliation to her debased ego. She was beginning to enjoy it, enjoy the lewd anal screwing her lover was giving her while McLean continued to fuck her in front. No! No! her mind screamed as she lay sandwiched between the two sweating male bodies, trying to will the rising tide of pleasure to ebb. But she failed.
"Oooohhhhhhhhh…" a low pitched wail of animal-like pleasure rang out… she couldn't resist the primordial call of her body any longer. She liked it. She liked being buffeted like a scrap of paper in the wind, mercilessly battered between the two heaving bodies. Masochistic ripples of pleasure eddied along her spine as she began to revel in her complete subjugation to the two men. She began to glory in the power they had over her, not only physical power but their potency which invoked such responsive delight in her. They were like wild stallions, luring her, the domestic mare, out to the bitter-sweet freedom of the plains, and she had responded, throwing aside the security of suppressed sensual excitement for the excrutiating sweet agony of a completely freed libido.
