As Alyvia stepped out onto the 3rd floor balcony of her house and felt the night air breeze blow her long hair, she shifted excitedly as she spread her large black feathered wing. And in a flash of movement, took off with blinding speed, homing in on the bottle's signature. Weaving through the nearly deserted streets, gone before anyone knew she'd flown by. As she reached her destination, a 4th floor apartment, she muttered a few quick spells. Greater invisibility to keep from being seen or heard, phase shift to pass through walls and doors like a ghost. Checking that all the items she needed were in her bag one last time, Alyvia passed through the window and into the hallway outside the bedroom. Inside, she heard a man and woman speaking to each other. She passed through the wall and into the bedroom, seeing the young couple sitting on the bed, the human man trying to get his, whatever she was to him, to try the potion with him.
"The lady at the market said this would give us a night we would never forget, and even offered a full coin back if we didn't like it," the man, about late 20s and rather skinny and unassuming, said as he held the open bottle in one hand and caressed the woman's shoulder with the other.
"It's safe isn't it," the woman, about the same age, asked. Her mousey voice squeaked when she spoke, a very timid woman, and similarly unassuming with non existent breasts or any real figure for that matter.
"They wouldn't sell it in the market if it wasn't safe would they, the regulators would shut down any harmful substance sells." It was true, Alyvia had to use some powerful spells to charm the officials to ignore her stall. "We've been talking about spicing up our life and this might be it. So let's try it." The man pulled out a pair of empty wine glasses and poured half of the potion in each and offered on to the girl. She hesitated, but then accepted the glass and the 2 gulped down the contents.
Alyvia reached into her bag and had a quill, full inkwell and cloth hover around her while she opened a leather bound journal to the first blank page she found and began to write. (Potion number 194: subjects, both human, man and woman, took half each.) She heard a gasp and looked up to see the 2 begin to kiss and rub each other over, lust in their voices. Alyvia had the pen and book hover and had the pen write down the observations while she took care of herself, reaching under the dress and began to play with her clit. She loved this feeling Maximillian gave her, opened her eyes to. As an angel, you were supposed to shunt such behavior, but to her, 'fallen angel's should mean enlightened. These mortals would be their playthings as they should be, not watched from afar like the ascended wanted.
The couple's moans got louder as the first changes began, making Alyvia's heartbeat become rapid with anticipation. The two pulled away from each other as they felt their clothing become tighter in areas. The man's pants were being tented by a growing erection, a wet spot of precum was seeping out of the tip. The woman was feeling up her flat chest as it pushed out slowly, beginning to put strain on her button up shirt. She brushed her hair out behind her ear and Alyvia could see the tips growing into points, the man's was as well. The man couldn't take it and began pulling off his clothes as quickly as he could, tearing come in the process. The woman still felt her chest as it pushed out, now to B cups, buttons were slowly popping off. The man pulled her further into the bed and straddled her, a button hitting his chest as it popped off. He began to reach under her skirt and rub her through her soaked panties. As he did, her hips and butt grew to match her breasts which were now near C cups. Alyvia continued to pleasure herself, letting her other hand grope her large soft breasts.
The couple's bodies began to thicken with a light layer of muscle, when something changed. The woman began to get more aggressive and pushed the man off of her and then rolled over so she was on top. Her nails lengthening into claws, she then grabbed any clothing she could and ripped it to shreds, leaving her naked and grinding on the man's lengthening cock. She raised herself up and guided the man meat into her with elated moans. As she rocked back and forth on him, she bared her teeth in ecstacy along with the man giving Alyvia a good view of their teeth growing into long fangs. As her pumping increased in speed, their skin tone shifted slowly from their fair complexion to deep almost purple black and their hair changed to white like a dark elf. Then the bed began to creak slightly as the woman began to slowly get bigger and bigger than the man, both gasping at their furious mating. Alyvia began to loose sight of the man's lower half as the woman grew until she was nearly twice his size. And she bent down to whisper into his ear. "This was a great idea my little fuck toy," the man seemed so surprised at her voice that it temporarily snapped him back to reality. "Terra what's happening to us? OH GODS, I feel like I'm loosing myself." 'Because you are silly mortal,' Alyvia thought as she fingered herself faster. Maximillian's potions changed the body but also diminished their minds to either mindless beasts or so they only though of themselves as they were now, loyal to the organization. He groaned again, the humping woman joined in as her rear grew faster than ever along with her thickening legs. The skin stretched and then tore away, revealing a massive black spider's abdomen complete with spinnerets. Her thick legs had gave way to 8 large and powerful spider's legs. From the waist down, the 2 of them had become large spiders, driders. Alyvia could see the man's much smaller body beneath the woman's, her own legs able to lift her off and over the bed if needed. The transformation had caused them both to climax, the man pouring everything into her womanhood. As he finished he looked lovingly at his larger mate and her at him. Then in a flash, she opened her mouth and began to quickly devour him. 'As if such things with some spiders, didn't even know Male driders were possible,' Alyvia thought. Then, as she finished her meal, the woman groaned and clutched her midsection. "Uugh, Robert where did you go?" 'Is it not done transforming her?'
The woman belched and groaned and she used one hand to hold her belly, and the other to her head. "I feel foggy, can't think straight. Gotta....gotta..." her eyes, once blue, were consumed by red. "Gotta make my army." She growled, and 2 bulges began to push out from below her arms and below her swollen DD Cups, forming a second set of arms and breasts. Then her head pushed upward slightly and 4 slits formed on her longer forehead, becoming 2 new sets of red eyes. As she stumbled on her legs and moaned again, her abdomen swelled even larger, growing to twice its original size.
She seemed to look around for a bit and then set the end of the abdomen near the ground. She grunted with an exertion and a large egg pushed out, followed by another and another and another. "You will serve me well my children. This gift will be used well." Alyvia finally came, and after composing herself, she dismissed the invisibility spell and strode forward.
"Intruder! Die insolent welp!" The monstrous drider swiped with one large claw, but was stopped by the thumb and ring finger if Alyvia. "You are mine and by extension, belong to Lord Valentine," Alyvia said calmly. As she spoke a rune appeared in the chest if the drider and her fight diminished. "I serve the one that gave me this gift. As do my children," she rumbled through her venomous fangs. Alyvia held out a box and tapped the circle on top, opening a portal and pulling in the drider and her unmatched young.
"Thank you, that was nice to watch. And you'll fit in well with us," Alyvia giggled sadistically at what the creature could do.
