Concept
We actually live in a virtual world that's forgotten it's origins in a solidified fantasy of science, created by the current master (name?). The Ancient Myth's all tell the true story. Periodically, "warriors" are born into the world, with true 'free will' and control, who have a chance to change things, either to become shepherd (rule, control) over the currently world, or ascend to fight the War for control the Holy Sanctum over all worlds.
On their coming-of-age, they are given a holy servant (angel), who will guide and fight with them.
Characters
Devon - 19 y/o teen, about to become a Divine Warrior
Amy / Amara - his Divine Protector, masquerading as his girlfriend
Reference
Ideas
?? maybe she "fights" him to force him to remember his true name
?? maybe they 'broke the truce' and now there are divine warriors revealing themselves all over earth
-> mostly as a motivation for them fighting among humans
?? maybe a different busty divine angel seduces, then restrains him and precipitates the whole thing
-> and he is narrowly saved by his own
Story
A teen and his girlfriend play their favorite MMO, where she has a super sexy, tall, and busty character she gets a kick out of. At the end of their gaming session, he wants to fool around, but she realizes they skipped dinner and has a strong desire for a cheeseburger. / The next day, they graduate from high school, and go out in the city after to celebrate. Someone mentions family, and he gets upset because he lost his family as a kid. He heads outside, gripping a bracelet from his father. Two darkly dressed men approach him, asking 'that bracelet looks expensive, is it worth dying for?" He looks up to see a gun pointed at him. His g/f opens the door to the alley, sees the situation, and cries out to him. He hears the gun pointed at him ring out, and instantly knows it's the end. He sees a blur of light and is knocked off his feet. When he comes to, he hears his girlfriend's voice, though it sounds different. "Are you okay?"
He hurts all over, he can barely pry his eyes open, and when he does, he is not prepared for what he sees. The girl leaning down over him doesn't look like (real g/f name), but someone astonishingly beautiful. (description) She sees the confusion in his eyes, and gives him a moment, during which his eyes draw down and stop, staring at her chest. "It's not the time for that." she lifts his chin. "It's me, (real g/f name) and (avatar name), well, both really. I'm your angel. I have some explaining to do, and this isn't going to make sense at first. You are not a mortal man. You are a Divine Warrior, and it's time for you to fight for your destiny and the destiny of this hyper-plane, and maybe the entire Simulacron."
"What the fuck?!" He blinks, the reality of the girl in front of him still sinking in. Her costume, her tits, the huge axe on her back. "This is fucking crazy. Am I dead? Dying? Hallicunating?"
"No, I'm afraid it's much more complicated than that." She backed away, reaching a hand out to help him up. He took it instinctively, and as he stood up he found himself even more shocked, as she was massively tall, standing more than a full head taller than him. Just like Amara. He could recognize her now. It was Amara, his girlfriend's character from the MMO, only she was standing in front of him in the real world. "Holy shit. I'm dying AND hallicunating."
"Shit, name. Now that they know, you are in massive danger. You need to take your divine form. Your bracelet, hold it, and say it, say your divine name." He fingered the bracelet, then looked back at her, perplexed. "Shit. Shit. Shit. I though I had more time. I need to get you out of here." She aggressively reached for him, and he tried to dodge but failed, as has hand caught his forearm. He yanked, expecting to pull away, but instead hurting his arm and shoulder as her grip didn't flinch, her arm didn't budge. "I'm sorry. I promise I'll explain everything." She pulled him in, roughly forcing him against her body. "In your human form this is going to hurt, but if you hold on tight it might hurt less." Then she looked up towards the sky, and chanted loudly, "caelum potentiae, domum tutam."
He felt the ground start to shake under his feet, and felt warmth on his skin that told him whatever was happening, she wasn't kidding. He grabbed hold of her, buring himself into an impossibly sexy body in a way that under different circumstances might have been quite appealing, but in the moment was just fucking scarry. They were basked in light, her whole body began to vibrate, as did his, then he felt like his entire body was being torn apart, and a moment later everything suddendly stopped and he couldn't hold onto her anymore, falling painfully to the floor as smoke rose and small stones, or maybe crystals, fell to the floor around him.
"We should be safe here for a while," she declared. He looked around. The room was dark but glints of light were filtering in through colored windows. They were in a church, and he had no idea where they were or how they got here. She sat on the wooden pew in front of him, making it look comically small, though it was her that was impossibly large.
"Who are you?" He said, struggling back to his feet. "I mean, you look like Amara, and you sound like (real g/f name), but who are you? What are you?" He stepped towards her, as if it would dispel the confusion. Though it only created more, as her unusual size, and huge tits spilling out of some kind of crazy battle armor were even more distracting up close.
"I am Amara. For three years, I've been by your side as (real g/f name). I've gone by many names over the centuries, Angel, Demon, Protector, Genie, Yogi, Buddha. My form is decided by the Divine Warrior I serve. You see, this world, this dimension we live in, is not the only one. It's just one layer of a deep labyrinth we call the Simulacron. You are, like your mother and father before you, a Divine Warrior. It is your birthright to enter the First and Last War. The only war that matters, the war for control of the Simulacron, including this world and every other.
He violently turned around, shaking his head, "this is fucking crazy." Then he turned back to face her, not totally certain she would still be there, not totally certain she was real. She was still there. "And to claim this birthright, I hold my bracelet and say my divine name. What the hell is that? My divine name?"
"Only you know it. You don't remember?" He shook his head, and she looked up, "Heavens! He's supposed to know! What am I to do now?" He wondered if something was supposed to happen. Nothing did. "Well, I guess I'll protect you until you remember, and then we'll begin your destiny. I just hope it happens soon, as your mortal body is frail, and if you die before transforming, well... let's not let that happen. Are you hungry? Our divine forms don't need food, but I still have a nasty craving for a cheeseburger."
Something about her intonation, and the way she moved as her hand touched her stomach, was more real, more believable than anything he'd experienced since the gunshot."Amy? This is really you?" He stepped closer, touching his hand to her face. She smiled and suddenly feelings rushed in, how much they cared for each other, how he trusted her. "It's all true. This is really happening." A small tear formed at the corner of her eye, as she smiled and nodded. He touched her hair, then ran his hand down her neck, settling on her shoulder, which felt the same but different. Then he looked down at the crazy amount of cleavage and skin showing straight down the middle of her armor. "Wow. You're even hotter than you were in the game."
"Ohh (name), you are my Divine Warrior, and you could have been killed!" He felt her hands under his armpits as she stood, lifting him into a firm hug, his belly bent around and stabbed by the uncomfortably rigid armor wrapped around her massive tits. "I will protect you until you remember your True Name, and together we will be strong enough to enter the FIrst and Last War."
"Uhh, Amy? Amara?" he said with the great discomfort. "You're hurting me. That armor, it's kind of..." Before he could finish his sentence, she had reacted, dropping him to the floor just a little too abruptly.
"Ohh, I'm sorry my Master. I will be more careful. I should return to the form of Amy, as it's more comfortable for you, and less conspicuous on this plane of existence." She crossed her arms, and looked to be preparing for something. He quickly held out his hands to stop her.
"No, no, wait. Did you just call me 'Master'? What did you mean by that? Exactly what are your obligations to me?"
"Right. Master. Yes. There is so much to explain. We are a Divine Union, and you are my Master, but in the ancient meaning of the word, which is a bit more like... Leader? I'm not you're slave, if that's what you're thinking. I am an immortal and non-corporeal part of the Simulacron, here to answer any question, and guide you in your destiny. I will also protect you, and fight for you, and provide companionship in any way you need or request. Since I have no natural form, you may give me any form you wish.
"And now you don't sound like Amy at all. She and I cared for each other, loved each other. Is that gone? Is it ice warrior Amara from here on out?"
"As I said, there is so much to explain. Amy is a part of me, but not all of me. Her personality matrix is bound her form. May I take that form now, so you can see her, and we can get something to eat?"
"This is all making you sound like some kind of artificial intelligence. Are you human? No, you're not. That's a dumb question. Are you real? Like me? Or something else? Can you be Amy and Amara at the same time, or is it either or?"
"These questions are difficult for even me to answer, and I fear every moment you don't remember your Divine Name is putting you in danger. If it would allow you to focus better on your destiny, I can integrate elements of Amy into Amara, so I don't seem so much like an 'ice warrior'." He nodded, and she closed her eyes.
The moment she opened them, he could see something was different. "Hey honey," she said, sitting on the bench. Every bit of her movement was casual, different, and markedly Amy. "I told her you would respond better to me, but she's trying to fulfill her duty for you to transform, and she takes it very seriously." She patted next to her. "Once you do, we'll work out the kinks." She looked down at herself and smirked, "this form was my idea, and from the fact that I'm still in it, I can see you approve?"
"Amy? This is so confusing. Are you real? Are 'we' real?" He was trying to be polite, but what he selfishly wanted to know was whether he'd be having sex with this unbelievably hot creation sitting before him.
"Ohh (name)," she reached out, cupping the side of his face in her large hand affectionately, and leaning down for a brief gentle kiss that was unmistakably Amy. "Of course we are. We are more than real, we are Divine. Here people live out normal human lives. We can spend thousands of years, even millennia, navigating the labyrinth, trying to reach the One Core. I don't even know how many worlds there are to travel through, and in every one of them, we can be whatever we choose. We can rest anytime you like, and live out dozens of 'real, normal lives', and then resume, until we reach the Core or we are bested by another. I tried to tell you this, that we were destined to be together forever, but there really wasn't any way to say it without you understanding all of this, and if I had just told you, you never would have believed me.
"So during this Divine Destiny, you're still my girlfriend?" She showed him a caring smile, reached for his hand, and held it against her leg affectionately.
"Uhm, I'm a bit more than your girlfriend now, my love. We're immortally bound and inseparable, so I hope you like being with me for a long time. Though my personality is quite pliable, if necessary. You still look like you have a question."
"Are we still going to do stuff we used to do? You know, like sleep together?" She immediately smirked.
"Ohh I see. Aware of your destiny for less than an hour, can't remember your Divine Name, and the question burning a hole in your brain is if you get to have sex with this sex pot body I made for you?" She took on a serious scowl, and lifted his hand off her thigh. "Ohh honey, you have no idea."
He watched the formerly rigid armor on her left breast peel open, as if alive, as she pressed his hand into the biggest, firmest, most attractive breast he'd ever seen. "I've been giving pleasure for hundreds of thousands of years. When you have your divine form, you're going to feel things you've never felt before."
He was only half listening, thoroughly distracted by the contact with her impossibly sexy nakedness. He ran his hand towards her side, and marveled at the armor peeling itself out of his way. "So I have to get my divine form first, then?"
"Oh no, my love," She rose, taking a dramatic step as her armor peeled off her body and fell to the floor. She was left in only thigh high black boots, as she turned to face him in glorious nakedness. "You really do trust me, don't you? To let me take you with this divine warrior body before you've transformed." She slinked closer, kneeling over him, her tits conspicuously descending towards him, before landing firmly in his face. "
