Chapter Five

Mac had gone undercover in the Wiccan to discover if their prime suspect in a rape charge was indeed the sexual predator that the complainant had claimed he was. CPO Merker was also the High Priest of a Wiccan, practitioners of the art of witchcraft. That term no longer held the same image of evil that it used to. Wiccans were becoming more and more a recognized religion in the United States.

While her partner, Commander Harmon Rabb, conducted an overt investigation of the charges. Mac assumed the identity of a Navy Petty Officer and infiltrate the Wiccan.

She had gone through a number of initiation ceremonies in which she had been exposed to a drugged ash that defied detection. During those ceremonies, she had stripped along with the other members of the Wiccan and danced joyfully around blazing bonfires.

But on this, her final night of her initiation, she was offered to the Wiccan's Lord's shell. The shell was in the body of a large snow white Ram. The large, virile animal had a huge ebony phallus that Mac soon learned was meant for her.

Because of the mind controlling effect of the ash, Mac subjugated herself to inter- species sexual contact with the beast. She had sucked the Ram dry to start off with. Then she was offered to it for intercourse. A marriage Merker called it.

During this whole ceremony, CPO Merker was finding it nearly impossible to resist his own sexual urges. Mac had him mesmerized at her sexual prowess. But he knew that he had to maintain his vow of celibacy so that he could keep his hold over the members of the Wiccan congregation.

When we last left her, Mac had accomplished the apparently impossible feat of taking in all fourteen inches of Ram cock into her womb. But still she wanted more from it. She wanted to feel the animal fuck her. Fuck her like only an animal could.

She bucked her ass against the Ram's groin to urge him to keep humping her. It didn't take much urging to convince to do just that.

"Oh yessss," Mac moaned. "Fuck me. Lord, fuck me good."

The congregation cheered on each time she used the word 'Lord' in her vocal outburst, mistakenly believing that she was in fact praising their religious Lord.

Mac could feel the Ram's cock pull almost completely out of her pussy, then just ram it back into her with such force that her knees bounced off the ground with each thrust. In and out the mighty cock pistoned into her pussy, driving her mad with excitement.

Merker just stared dumbfounded as he watched Mac fuck his virile Ram into submission. No woman had ever done that before. Sure, many of the female initiates had gone through this ceremony. But none with such rapture that this dark- haired beauty was demonstrating.

With the others, he could see their reluctance in their eyes. He knew that their initiation with the Ram would be their last with any beast. But not with Mac. With her he felt that he had found himself a soul-mate. That as soon as she found the opportunity, she would be seeking a beast to satisfy her own sexual urges.

Mac had lost count on how many times she had had an orgasm under the beast's sexual attack. But by now she didn't care any more. Time and time again the Ram would fuck his full fourteen inches into the dark tunnel of her cunt. And each time Mac would grunt from the strain it placed on her innards.

Merker was hypnotized at the sight of her actually mastering his Ram. It had taken him almost a full year to find the virile beast, convinced that no woman could ever conquer him. But here, before him, he was witnessing the impossible and it was driving him nuts.

Mac's tits would be jostled with each fuck thrust of the powerful beast. They were bouncing fore and aft like balloons full of Jell-O.

"Oh Lord, yessss!" Mac yelled in orgasm once again. "I... I don't know how... how much longer I... I can take this."

"The Lord is our Master," the congregation droned on. "The Lord is good."

Mac could feel the hot breath of the large Ram against her bare neck. She could tell that it was getting shallower with each passing second.

'He... he must be getting near,' Mac guessed.

As if willed by her own thought, the Ram's cock exploded with a powerful ejaculation that nearly blew Mac's clenching pussy off of its cockhead.

Merker lost all self control at that point. Seeing his Ram's jet black cock blow its load deep into this initiate's cunt was too much for him to bear. He stripped off his cloak and knelt before the gasping Mac.

When she looked up she was met with his raging hard cock. Mac knew what the man wanted, and at this point she was too horny to deny herself his cock either. So, she leaned forward slightly and slipped Merker's eight inch cock in her mouth and began sucking him off as the Ram continued emptying his balls in her cunt.

Mac had never felt so filled in her life. The Ram's fourteen inch cock was at the deepest recesses of her vagina and Merker was filling her mouth with his own thick cock.

Merker kept up his humping Mac's face for a good three minutes before one of the congregation members noticed what was going on in their midst.

"DEFAMATION!" The man cried out, alarming all of the others to Merker's actions.

caught by his 'followers' triggered a panic response from Merker, as he felt his jism shoot into Mac's sucking mouth.

Mac had no trouble accommodating the man's cum. Compared to what she had swallowed from the Ram, Merker's was a feeble second.

"DEFAMATION!" A chorus rang out from them all.

"You attempt to steal our Lord's bride," the first man cried out.

"DEFAMER!" The congregation shouted.

Suddenly five of the men of the Wiccan grabbed hold of Merker and pulled him away from Mac's head, causing his cock to slip from her sucking lips.

Mac was dismayed at the turn of events. She had always assumed that they must of all been under Merker's control during all of this time. But it was now obvious to her that they did take this Wiccan religion very seriously, and that the Ram fucking her was indeed the shell of their 'Lord'. So Mac decided then and there not to cause any damage to their congregation in the courts.

The Ram remained oblivious to the trouble surrounding he and his mate. All that he cared about was to fulfill his duty in fucking the pussy under him. So, he began to hump anew into Mac's still clenching cunt. Though he had already emptied a huge load of cum into her, he was a very virile beast used to multiple couplings per session.

Mac immediately felt the renewed vigor of the Ram's thrusting. It didn't take her long to realize that she was about to get another master fucking from the beast. And truth be known, she was in no hurry to have him stop at this point.

"Go for it you brute," Mac cried out to the Ram. "Fuck me again. I want your seed in me. All of it. Don't stop until your balls are empty and drained."

Mac was getting enamored by the beast's virile fourteen inch cock. So much so, that she couldn't get enough of him. Regardless of the outcome of this JAG investigation, she felt sure that she would be spoiled, sexually, by this fucking.

As the congregation members kept holding Merker down in their anger, Mac was humping her ass back at the animal's thrusting shaft. She wanted to feel every inch of him inside of her when he unloaded.

Most of the congregation members resumed their worshipping position around the bestial coupling and resumed their chanting, ignoring the rutting twosome on the ground before them.

"The Lord is our Master," they chanted. "The Lord is good."

Mac found it unbelievable that they could do anything at all while she was trapped performing such an obscene and exciting sexual performance. She had to accept the fact that this act was indeed very seriously thought of by this congregation.

The Ram kept thrusting his rock hard shaft deep into Mac's willing pussy, raising her knees off the ground with each powerful forward thrust.

Never in her life had Mac ever had such a powerful lover. Most men that she had slept with in the past would be contented with a nice slow fuck, thinking that this is what she wanted. But after experiencing the brutal animal fuck of the Ram, Mac was considering looking for more bestial guys to sleep with in the future.

"Oh Lord!" She cried out as she came yet again, and still the Ram wasn't ready to unload. "I... I've never been... been loved this... this good before. You... you're fantastic," she moaned to the Ram.

Merker was trapped on his back, struggling to at least see the brunette get fucked by the Ram. But the two powerful men holding him down wouldn't allow him to desecrate their religion any further than he already had. So the CPO had to remain helplessly on his back with his raging hardon pointing in the air in frustration.

For the next ten, long minutes, Mac was subjugated to the fiercest fucking she had ever received. The Ram was fucking her as only a lustful beast could, savagely. With each thrust Mac felt her womb being shoved inside out by the powerful animal.

Already in the throws of orgasm, Mac kept averaging an orgasm every fifteen seconds or so. Which meant that during this beast's fucking her, she would have experienced no less than forty orgasm of her own. And despite her fitness, physically, she would have passed out from the sheer exhaustion of it all well before the halfway mark.
