It was finally time. Everything was ready, the only thing left to do was perform the summoning ritual. And yet, Adam couldn't help but be a little wary. Sure, he had spent his whole life (reluctantly) training for this moment. This was to be one hundredth Holy Grail War after all, and it was something his family had been involved in for generations, even if they hadn't been there at the start.

That didn't mean Adam was all that happy about it though. As useful as magic could be, technology was just so much better most of the time. It wasn't magic that had allowed humans to spread out across the stars and inhabit so many damn planets, after all! Needless to say, Adam would much rather be spending his time with his friends in a VR sim of some sort then doing this, especially given that it was somewhat perilous.

Sure, the rules around the Holy Grail War were pretty strict about killing Masters, but that didn't mean he was TOTALLY safe. No, there was always the possibility of some crazy fucker getting involved in the war and going off the rails, or even the possibility of a bloodthirsty Servant being summoned who couldn't be controlled.

... Ugh, and now he'd worried himself a bit more, because he couldn't be sure that he wasn't going to be the one to summon a bloodthirsty Servant who couldn't be controlled. Still, at the end of the day, it wasn't like Adam had much of a choice. It was what the family expected of him, and while he COULD have technically said no, he had no desire to be disowned and lose out on access to the numerous privileges that being part of a rich techno-mage family got him.

So yes, he was doing this, even if he had no desire to do it. He was doing this, even if he would have preferred to be enjoying his time in VR with some big-breasted babe instead. With a sigh, Adam shakes his head and steps forward towards the ritual circle he's painstakingly made. Having double and triple checked it by this point, both to make sure everything was in order and to stall for a little while longer, the young mage knows for a fact that it's ready for him. Everything is in order, everything is perfect... which means it's time to begin.

Back in the old days, Adam had read records of summoners using chants to bring forth their desired Servants. These days, doing a chant was only something the most obnoxiously haughty mage would do. It was commonly thought better to just... let the magic work with one's blood to summon the Servant most compatible with the summoner. After all, a chant was what you thought you wanted. Magic would give you what you ACTUALLY wanted, if you just went with the flow.

All things considered; Adam liked going with the flow. And so, kneeling before the circle, he cuts his hand with a knife, wincing slightly as he slices his flesh, and bleeds into the receptacle at the edge of the ritual circle purposefully made for his blood. As it pools, his blood begins to travel through the lines of the carefully constructed circle, and Adam watches on as the sigils and runes he'd spent time perfecting begin to glow with power.

His breath hitches as the light grows too bright for him to see in no time at all, and he raises a hand to cover his eyes and spare them from a blinding. Eventually, the light fades away and Adam slowly lowers his hand, almost reluctantly, somewhat wary of what he's going to see on the other side. The ritual summoning failing would be both the best and worst possible outcome.

For it to fail, after he was sure he'd done everything right, would mean that he'd actually spent too long waiting and the maximum number of Servants had already been summoned for this Holy Grail War. Of course, the family wouldn't accept that, and he would be tasked with repeating the entire ritual process a number of times until they were satisfied. At which point there would be considerable censure for his failure to take part in the family tradition that he'd been trained his whole life for.

At the same time, at least he wouldn't be involved in the Holy Grail War, making it a possibility that Adam found himself longing for all the same. But alas, when he finally lowers his hand and blinks the light out of his eyes, it's to find that he has not failed... indeed, he has summoned someone... and as he stumbles to his feet and looks upon his Servant, Adam can't help but gape.

Before him, a blonde vision of beauty smiles and leans forward, her hands coming together to clasp in front of her, which in turn has the added effect of causing her arms to squish her incredibly impressive mammaries together, providing him with both a look down her top and a great view of her absolutely MASSIVE tits. In this seductive pose, the blonde bats her eyelashes suggestively, licking her lips as she speaks in a coy, lilting tone.

"I ask of you... are you my Master?"

The glowing feel of the Command Seals on the back of his hand, etching themselves into his flesh and providing a mild discomfort, jolt Adam out of his stupor and he quickly answers.

"Y-Yes! A thousand times- I m-mean, yep! I'm your Master."

Raising a hand and giggling behind it, a movement that causes her fat milk jugs to jiggle just a bit with her laughter, his new Servant's eyes flash knowingly.

"That is good, Master. I hope that we can work well together!"

"You have the biggest tits I've ever seen, lady! And that includes in VR!"

And there it is. Adam regrets putting his foot in his mouth a moment after he's done it, but by that point it's too late, he's said what he's said. Luckily, the Servant doesn't take umbrage with his words. Instead, she beams and hefts up her gorgeous milk jugs as she rises from her kneeling position, giving them both an appreciative squeeze and grinning at him all the while.

"Indeed I do. Allow me to introduce myself, Master. I have been summoned before you as Saber... but in life, I was Arturia Pendragon, and commonly known as the King of Cleavage."

Damn straight he was! Adam drinks and drinks, absolutely losing himself in the taste and sensation of gorging himself on his summoned Servant's breast milk. She's absolutely beautiful, this King of Cleavage, and there's nothing he wants more than to play with her titties for the rest of his life. Of course, he knows that won't be possible, eventually they're going to have to fight a Holy Grail War. But before then, Adam is going to do his best to get personally and intimately acquainted with his new Servant and her big fat milk jugs.

And so he does, until finally he's drank as much milk as he can, leaving her breasts red and puffy in that way that a woman's breasts get when they've had an inordinate amount of attention paid to them. But if Saber is upset by that, she doesn't show it. Instead, she graces him with an affectionate smile, even as she sinks to her knees.

"You've done so much for me, Master. It seems only fair that I return the favor now. And I can only assume you have an idea of what you want me to use to pleasure you."

... Oh fuck yes. Adam hurriedly unbuttons and unzips his pants and yanks his cock out of his boxers perhaps a little more roughly than necessary. But how can he do anything less? His dick is soon in the open air and pointed unerringly at the King of Cleavage's... well, cleavage. Licking his lips, he steps forward a little uncertainly, unsure how to go about things.

Pressing her hands into her massive tits on either side, Saber leans in close, and lets him slowly ease the head of his throbbing cock in between her tits. He finds himself fucking her breasts horizontally, not something he thought he'd ever get to experience. But that's just how big Saber's titties are. They're so massive that his cock is easily lost in the soft, warm space between them, and Adam begins thrusting forward with all his might, groaning loudly as his hands come down atop her mammaries for support, gripping onto them for dear life.

In return, Saber moans as well, the King of Cleavage shuddering as he fucks her big ole titties. Her fat milk jugs jut forward on either side of his cock, pressing into his shaft with the help of her hands, and providing a love tunnel that's honestly better than any VR pussy he's ever experienced. There's no denying it, Saber's breasts are S-tier in quality, and the Servant herself is obviously S-tier for being such a thirsty breast slut and letting him do whatever he wants with her!

In and out Adam thrusts, again and again as he marvels at the maddening pleasure he's experiencing. This was... honestly, it was beyond any of his expectations for this War. And now... now he had every reason to win it too. After all, losing might not mean his life these days, but it would still mean the defeat and dissolution of his Servant.

If he lost a fight against another Master, Saber would 'die' and return to the Throne of Heroes, while Adam would be left all alone without these massive breasts to keep him company. In that moment, the somewhat lazy young man finds the motivation that he's been lacking his entire life. Put frankly, he'd never put much effort into anything at all unless he was forced to.

But now? Now it was like his mind was going a mile a minute. Even as he fucked Saber's massive rack to his heart's content, he was already having ideas, drawing up battle plans. He was going to win this Holy Grail War... just for the sake of keeping Saber at his side. The King of Cleavage was not going to leave him, not if Adam and his libido had anything to say about it!

His pace was growing faster and more sporadic by the moment, and Saber's cleavage was holding him tightly as she moaned and rubbed her tits along either side of his pistoning prick. Adam was getting closer now, and there was no more holding back, not with heaven itself embracing his cock. With a loud groan, he shouts out a warning to his beautiful buxom blonde bombshell of a Servant.

"S-Saber! I'm getting close!"

"Do it, Master! Creampie my titties! Cum for me!"

He doesn't need to be told twice. With a loud groan, Adam throws his head back and... creampies Saber's titties. Plowing in between her fat jugs, spurts of his hot cum land along her inner cleavage, that strip of flesh that hides so deeply in the recesses of the King of Cleavage's tits. He cums what feels like gallons, and he keeps on thrusting forward as he does so.

Only, as he's thrusting into the cleavage-creampie that he's giving Saber, Adam's cock slips and slides... and ends up vertical, pushed up until his balls are in his initial creampie and his cock itself is suddenly prodding out of the top of Saber's immense cleavage. With a loud groan at the sudden change in sensation and pressure, Adam finishes the latter half of his load ALLLLL over his new Servant's face, covering her royal visage in his jizz, with some dripping off and landing atop her massive mammaries as well.

By the time he's done, he's really made a mess of Saber, and in a moment of post-nut clarity, Adam blanches, worried that he may have upset her. After all, she'd told him to creampie her tits, not give her a facial.

... But he needn't have worried. In the end, Saber has an exultant expression of pure ecstasy on her face as she moans lustfully, rubbing his seed into her tits and licking his cum off of her lips and cheeks with her tongue. She looks absolutely fantastic in that moment, and Adam... Adam knows without a shadow of a doubt that he would be willing to die for her.

Perhaps that's a little extreme, but it's true. He's going to do whatever it takes to win this Holy Grail War and keep the King of Cleavage with him. And he's confident he's going to win too. After all, what do the other competitors have that's pushing them forward? Archaic concepts like honor and duty?

Little do they know... but he has the power of titties on HIS side! And that will make all the difference.
