Not long at all

To John's credit he gave you plenty of time to adjust to the sheer mass of the dick inside you. Mostly because he was to busy trying to devour your tongue first with another one of his deeply passionate and overwhelming kisses. At the same time he attacked your nipples with his hands, groping your chest while running your little nubs until the stops almost painfully erect, before pulling and pinching them to make you whine against his mouth.

After what felt like hours he started slowly moving his hips. He pulled out only slightly before grinding back into you, often circling his hips around as if trying to widen your colon and stretch you out even more. The pressure he put on your colon was constant, and his every move however small shot sparks up your spine. You whined and moaned like a whore under his attention and that only encouraged him to press you harder.

Ever so gradually he sped up his thrusts, pulling out more before pushing back into you faster and faster. Your whole body was soon shaking from the pressure as your mind melted more and more from the pleasure. Eventually he stopped kissing you in favor of starting to suck hickeys and welts into your neck and shoulders. Without his tongue to block your mouth you got louder as you sang his praises.

"Oh God! Oh Jesus! Oh fuck!" You cried out as he was now pulling almost seven inches of cock out of you time and again before slamming back into you. The thought that he was yet to come anywhere close to pulling out completely filled you with a glorious longing to be taken even harder.

"Please alpha!" You begged without wanting to admit what you were begging for.

"Please what?" John asked all to innocently. "What does my love want? You know I would give you anything. Is it getting to much for you? Do you want me to stop?"

Without any thought needed on your part, your legs immediately closed around his waist as you heard his teasing threat. It was a threat, you thought, if he stopped fucking you now you might very well die. Despite the obvious sign from your body he did slow his pace as if he was going to stop for real.

"Don't make me beg alpha." You whined in-between another sinful moan as he began to suck on one of your nipples.

"You'll never have to beg for anything my love." John declared. "Just ask and I'll give you everything you need. Kids, money, a den, the world, anything you want all you have to do is ask."

"Fuck me harder!" You cried out. "All I need to live is that alpha dick please!"

He slammed into you like a sledgehammer with those words and knocked the breath out of you. While your vision slowly recovered from going completely white again, he slid his hands down to your hips and straightened himself out to get better leverage. Then he went to town on you.

His efforts to destroy your ass started with him almost completely pulling out of you. This gave you the first real glance at his cock you had ever gotten. Even with his head still lodged in your colon there was enough man meat between your thighs and his pelvis to equal your forearm. How he managed to get all of that into you without seriously breaking something you will never know. Concern for his size was quickly driven from your mind though as he suddenly slammed back into you.

Before you even finished crying out from that first thrust he had pulled back again and then railed right back into you. With his hands holding your hips like a vice he was free to pull you out and in at the opposite rhythm of his hips slamming back and forth, essentially doubling the speed at which he could fuck you. His pace was absolutely brutal and you swore he was somehow getting faster. You absolutely loved it.

There were no more words that could escape your lips. No oaths or curses you could utter. Your mind was completely blank, all other thought and sensation driven from it as his dick overwhelmed you. You were gloriously and wondrously broken. You still sang his praises though in a more primal tune. Moaning and gasping as breath was driven from your lungs over and over again.

You didn't even realize that your own penis had grown hard again until your orgasm suddenly crashed down on you. You only managed one or two proper shots of cum through before the rest just dribbled out of you. The mind blowing sensation of all the muscles in your ass spasming seemed to go on and on for much longer though, not at all helped by the fact that John didn't stop fucking you for a second throughout the entire ordeal. Only when you finally started to come down from this inner explosion did he finally pull out.

As you lay collapsed on his bed, John stood up and started to manhandle your body to shift you around. You suddenly found you head lying off the side of the bed with you legs crossed under each other so that you wouldn't press against the wall to the side. John stood in front of you having stripped away the rest of his clothes. In a daze you were left to look up him worshipfully. His toned six pack, his broad shoulders, his thick limbs and his sun kissed skin, he was a perfect figure of masculine power and grace. You had always known he was good looking, now you suddenly realized he was absolutely beautiful.

He was also still very, very erect. Somehow bringing your to orgasm twice hadn't yet gotten him off even once. This seemed a crying shame to you because you were completely spent, if he had another go on your ass you knew it would push well past pleasure into the pain of oversensitivity. Your heart broke at the thought that you couldn't pay back the man who had given you so much pleasure so quickly, but it seemed John knew just how to solve this problem.

With one hand he grabbed the bottom of your jaw to open your mouth up and with the other he guided his dick into your other entrance. Without thinking you licked around his cock head and his slit as it came within your reach, but soon your tongue was all but trapped in place as pushed into the back of your throat. You half expected to **** and gag on the mass of meat being fed to you, but your body had all resistance fucked out of it by this point and it seemed even your gag reflex had given up and left your throat pliant and stretchy to accommodate him.

"This is probably the biggest reason you should be an omega." John commented idly as he started to gently fuck your throat. "Omegas don't really have a refractory period. After you fuck the first shot out of them they quite easily settle in to have dry orgasms over and over again as you go to town on them. Just think about that Tom, you could still have me pounding away at you right now, instead you'll have to settle for just blowing me for the next ten minutes before I can fuck you properly again. Not that I'm complaining, your throat is almost as divine as that ass of yours. Maybe I'll take you into to work with me one day and leave you under my desk so I can enjoy it properly. You won't even need to come out for lunch, I'm sure my balls can provide you with all you'll need to get through the day."

You couldn't really focus on what he was saying. Since you were still flipped on your back his balls were now gently slapping into your face over and over again, filling your nose with his powerful alpha musk. As a beta the scent didn't have as powerful an effect on you as it would if you were an omega, but with such a powerful source of it so close it hardly mattered. Besides that your mind still hadn't recovered from all the pleasure you had received earlier so you stayed soft and pliant. Your whole world still only consisted of this mighty dick that had so completely destroyed you.

It was so wonderful and perfect, so massive and masculine, so overwhelming and dominant. You loved this dick that had filled your insides with bliss. Your worshiped this cock that had reduced your brain to so much mush. You lived for this schlong that had made you into a sex toy for a others pleasure. You existed to be ruined and ravaged by this absolute monster.

You sucked and drooled on John's dick as much as you could as it plugged up your throat, doing your damnedest to be as good a slut for him as you could. He moaned contentedly as you did and smiled at you. He called you his good little slut as he pet your hair. You watched in fascination as you swore you could see his balls swell slightly in size as you continued to go at it. You don't know how long he made you suck him off, but you weren't really sure how long the two of you had been having sex either. Eventually you felt yourself starting to get hard again, and he pulled out of your throat.

Again John moved your body around like his own personal sex doll, lying you back on the length of the bed with a pillow under your head. He straddled your chest and dropped his dick on to your face. You instinctively cuddled up to it and started licking it, trying to pay it back for how good it had made you feel. John pressed a part of his dick near the base close to your eyes and it looked to you like it was starting to swell up a bit.

"See this?" John asked wrapping one of your hands around that swollen bit of flesh. "This is where my knot is starting to form. That how much you've turned me on Tom. Your slutty little beta ass is going to make me pop a knot for you, that's how perfect for me you are. Of course I can't actually pop it in you. Not while your a beta anyway, that actually would break something in you. If you were an omega though I could knot you properly."

"You know getting knotted is the best thing that can happen to an omega right?" John continued. "It locks you up so none of my cum can leak out of you, making sure it all flows right up into your cervix so you can get knocked up super easily. Makes an omega feel like they've fulfilled their purpose in life, all the whole stretching them out to their fullest and completely crushing their prostate or g spot. It all leads to a kind of rolling orgasm, so that you just kind of cum continuously for like five minutes straight. Lasts even longer if your in heat. It's literally mind blowing. Once an omegas been knotted, it becomes just about the only thing they can think about. Doesn't that sound amazing?"

It really does. You open your mouth to declare a transformation into an omega so that he can do just that to you. But John silences you with a finger to your mouth.

"Not this time Tom." He forbids you. "This time you take it like a beta. Next time you can be an omega for me and learn what real pleasure is. But this time you'll have to be satisfied with just me fucking your brains out and filling you up with a real alpha's cum. Now let's flip you over and fill you up."

In just a second you found yourself flipped over onto your chest, your legs spread apart and that glorious dick pushing up into you again. This time John didn't take it slow. He didn't give you time to adjust, but you didn't need it. He slammed into you, pulled out to his very tip and then slammed back in again. In seconds he was doing his best to fuck you into the mattress, or perhaps even just fuck you through it.

You bit down on the pillow in front of you to try and hold in your moans, but John pulled your hair to **** your mouth open so he could hear you fall apart all over again. Then he turned your head to the side so he could kiss you and steal your breath even as he pushed it out of your lungs. Your fingers dug into the sheets beneath you as you sought to find something that could ground you. It wasn't enough. You felt your precum leaking freely from your own dick as your insides caught and fire and quickly built to orgasm.

"I'm coming!" You cried after what felt like no time at all. You released what little semen was left in your balls as again you muscles spasmed around John's member. Once again John fucked you through your orgasm, but this time you felt his pace begin to stutter as you also felt something very large begin to knock against your asshole every time he pressed into you.

With a gutteral cry, John bit down hard on your shoulder, hard enough to draw blood. Sharp pain filled your mind, but only for a split second as the area where he had bitten suddenly turned numb, and then icy hot as an odd sense of relaxation began to spread through. But you could hardly think about that as John pressed as deep into you as he could without shoving his knot in as well and began to unload his sperm into your ass.

His semen felt blazing hot inside you as you felt his dick twitch as it fired round and round into you. Between that feeling and the bite you were pushed over into one last orgasm and your first ever dry orgasm at that to, since your dick was well and truly spent by this point. With his knot grinding against your entrance only some of his cum could leak out of you. The rest was pushed deeper and deeper into your bowls. You could feel it filling you up, trace its hot path through your intestines. You felt yourself begin to bloat up as his sperm poured into you. It was wonderful.

As your last orgasm faded you relaxed into the bed while John suckled and licked at where he had bitten you on your shoulder. He was still pumping spunk into your bowels. His orgasm just went on and on as he did his best to fill up every nook and cranny in your guts. Eventually it stopped, but his dick still felt massive inside you, you guessed his erection wouldn't go down until his knot faded. John pulled you over on to your side as he clutched you closer and cuddled up to you.

"So how straight are you feeling right now?" The smug bastard asked.

"Maybe, twenty percent straight." You teased back as your hands ran over your swollen guts. You looked about five months pregnant and could feel all that sperm sloshing back and forth inside you. You wondered if this is what it would be like if you got pregnant. The thought excited you.

"After all that you still think you have some straightness hidden away in you? Maybe I should've fucked you harder then." John declared.

"Maybe if you had let me become an omega for that last bit I would be completely sold on this whole, letting an alpha fuck me, thing." You said with a wide smile on your face while John nipped at your ear.

"That would've made you straighter though." John stated.

"Letting another man try and knock me up would make me straighter?" You asked incredulously.

"Of course." John answered. "Everyone knows that straight sex for an omega is getting topped, whether it's by a man or woman doesn't matter. Just like how straight sex for an alpha is topping someone else."

"I'm sorry are you implying-" You started to ask in disbelief.

"That after all this I'm still straight as an arrow," John confirmed. "But you're gay as hell."

You broke down in laughter after that statement while John just smiled and started pressing kisses into the back of your neck. It was good to know that despite having confessed his feelings for you John could still joke with you like the asshole he was deep down. Maybe having your best friend as a lover wouldn't be so bad.

You weren't certain how you actually felt about him. He was sexy and gorgeous, fun and protective, he was great at sex and you really did want to find out if he was telling the truth about that five minutes long omega orgasm thing. He certainly had his life together more than you did so being his mate wouldn't be a poor life choice, in fact it was probably the smarter thing to do all things considered. But did you love John the way it seemed that he loved you? You weren't sure.

"How long are you going to keep your dick up my ass?" You asked to distract yourself from these introspective questions.

"Until my knot goes down." John explained. "Do you not want my dick in you anymore?"

"After tonight your dick is welcomed in me whenever it wants to be there." You told him and you swear that John pulled you tighter to his chest after those words. You continued, "It would be nice to get cleaned up though."

"But I like you when you're covered in slick and semen." John whined. "Makes you smell almost as good as you did when you were an omega."

"How did I smell then?" You asked curiously.

"Like pure temptation and sin, with a minty undertone." John said as he pulled the covers over the two of you and started running at your bloated tummy. "It took all my strength of will not just throw you on the bed and take you as soon as you finished transforming. If you changed right now I would have my teeth in your mating gland in seconds to make you mine forever."

You shifted your ass back and forth while grinding down on his knot at those words. John moaned sinfully in response and then turned your head to face him so he could give you another kiss. It didn't last as long as the others had, but it was still deep and loving.

You felt really good right here. Wrapped up protectively in your alpha's arms. A load of cum in your previously virgin ass, proof of how deeply you were loved and cared for. Warm, content and happy about the future. Life was good right now.

When you first made this ABO world your plan had been to make yourself an alpha and then see how many omega girls you could get hooked on your junk. Maybe settle some old scores by turning your old bullies into omegas and leaving them on the bottom of the totem pole. Now you were in the verge of getting hooked on another man's junk and were wondering how good it would be to spend the rest of your life as a precious and cared for omega. And this seemed way better to you than any of your brief fantasies had been.

Hopeful for the future with John you let yourself drift off to sleep in his arms.
