Now or never!

Xandra valiantly fought of her urges.

"Now" she said. Without further ado, she teleported all three of them just outside the church. It was obvious, the night events woke up everyone - the obscene sounds of all-out orgy from houses, cars and even bushes, were so loud, Xandra doubted, the sisters could sleep anyway. Especially, when she recognized moans of the priest from one of the sound sources. This was good, she thought. Without priest, and his holy power, the whole thin would go far more smoother. Without hesitation, the trio entered holy grounds, then the church itself. Their hybrid nature made them immune to all protections of this place, and soon, they were inside, their prey in sight. The nuns spun around, when the doors creaked, then screamed in terror, when saw naked, inhuman beauty of the hybrids. Not wanting to lose element of surprise Xandra quickly chose, and with one jump simply killed with her claws two oldest nuns, their blood splattering both the remaining trio, and her. She licked her lips, then chin, then her neck, and breasts with her inhuman tongue, savoring the most glorious of all forms of life, terrifying remaining nuns into almost catatonic state. Since ritual required of them to be awake and aware through all of it, she simply stood menacingly, over them, stroking her cock, and scooping bits of blood from her body, and tasting it with pleasure, while her thralls prepared ritual. While they did that, Xandra assessed soon-to-be sacrifices, and found all of the extremely unremarkable - plain girls, without anything to stand from crowd, but at least, all of them in perfect physical shape, and - more importantly - virgins, as their auras betrayed.

Xandra smiled wickedly, as her thralls finished their tasks - using blood of the dead nuns, they drew ritual circle with triangle written into it, with altar which they defiled with their cum in the center. At each peak of triangle was smaller circle surrounded by runes of the most dark and forbidden nature. Deciding it was the time, Xandra linked her mind with her thralls, the working as one body, followed Willow's instructions.

With ease, each of the hybrid picked one of the nuns, ripped her clothes, till she was naked, then placed in one of the smaller circles. With grin of pure evil, Xandra observed nun's body squirming under her grasp. Even if physically unattractive, the very idea of **** the nun, made her looking like most desirable object in existence. Then, instructed by Willow, Xandra lowered her body to penetrate her victim, but to the nun's surprise, it wasn't her pussy, Xandra's cock pressed against. Her eyes bulged in terror, as she realized, what was about to happen. With all her demonic strength, Xandra **** her swollen cock into young woman's ass. With all it's girth, pointy nodules, and complete dryness of the hole it seemed impossible task, but bit after bit Xandra's swollen cockhead defeated muscle resistance of the nun, then popped through her sphincter. The nun screamed as much of pain as defeat, as she felt sudden warmth, of Xandra's precum entering her asshole, lubricating it a bit, and invoking feelings, she never experienced before. Grinning wickedly, Xandra **** more, and more of her cock into her unwilling victim, as she felt her thralls doing the same. As she went deeper, she felt her cock excreting more, and more of the precum making the penetration easier with each second. But when she was buried half way, Xandra lost her patience - with one, powerful thrust, **** her whole cock into the nun. The woman screamed savagely with unison with her sisters, as Willow and Bufffy did the same. For second, Xandra savored exquisite tightness of nun's rectum, then withdrew almost completely, to slam her cock inside again, making nun scream even louder, then started to fuck her with all her might. As her thralls did the same, she felt resonance from the circle, as their forbidden act drew powers of her closer to them to make their evil act part of it. Feeling enormous wave of power nearing, Xandra increased her pace, and in few strokes, she felt her cum entering nun's bowels, as hermaphroditic hybrid screamed final words of ritual in unison with her thralls.

Then it happened. Without sound, or warning, the barrier of Hellmouth ripped apart, and all power of hell poured through the hole, right into the circle. Xandra felt, as through the nun, like living conductor, magic streamed right into her, instantly offering it's limitless capabilities, and demanding it's price. With joy, Xandra offered her victim whole, body mind, and soul, and saw nun's body simply disappearing into nothingness, as she was sucked into the hell, then willingly sacrificed part of herself to finalize her contract: her womanhood. Instantly, she felt her pussy, womb, and ovaries disappear into nothingness, as her body Instantly changed accordingly to her wishes, to be able to handle her new power.

In one flash it was over. As hybrid trio absorbed all the magic that broke through, the barrier mended itself, when amount of power on both sides become at least partially equal. But still the amount absorbed by Xandra and her thralls was immense, and their bodies responded accordingly, by changing to accommodate new power. As she summoned her image in front of herself, Xandra saw breathtaking sight. She no longer stood on her feet - instead her thighs ended with double knee, and her shins in jet-black hooves, contrasting strongly with her blood-red skin. Her waist shrunk to almost impossible proportions, with greatly accentuated abs on it. From her back grew thick, four feet long tail, with ending unnervingly reminding of cock head. Her chest grew in width, and her tits grew into perfectly round, gravity defying EE-cup size, juggling seductively with every move. On her back grew great bat-like wings. Her face was triangular in shape, with perfect proportions and symmetry, and long black, hair around it. From her forehead, grew small, black horns. Her eyes glowed in red and orange, like flames of hell, her elfin ears pointed outward her head, her seductive lips hid long fangs, and inhumanly long, forked tongue. Strangely enough, her cock didn't change at all, with exception of heavy ball sack underneath it, and lack of any female genitals. She smiled, wickedly, as she turned her attention to her thralls, and found them with almost identically changed into their perfect selves with small exceptions: Willow's frame was slimmer and more petite, while Buffy grew to impressive seven feet, with grealty accentuated muscles.

"Well" Xandra spoke, noting with joy her voice changed into most seductive sound she ever heard "What could three godlike-powerful shemale demons could do at night like this?" she asked with grin of pure evil.
