Damn right they do

"I am a beta." You suddenly announced as your twenty minutes time ran up and John's command kicked in. You hadn't been expecting it. In fact you had completely forgotten about it. John had quite thoroughly kissed every other thought and concern out of your head.

The transformation didn't seem to take as long as the last one did. You could hear your bones crack as they suddenly lengthened, your skin felt tight and stretched as you gained another few inches of height. Then sensation of your generous ass shifting up your body as the fat turned into more muscle on your chest and arms was extremely disturbing. You certainly enjoyed turning into an omega more than turning back into a beta.

"Well that was an interesting experience." You said thoughtfully as you prepared yourself to separate from John and evaluate what had happened to you.

"I bet it was." John said, his voice still heady with desire as he wrapped his hands around your head and pulled back down for another kiss. It was not a chaste kiss. He drove his tongue right back into your mouth, wrestled your tongue into submission and then continued to explore your every nook and cranny.

Your breath caught and your mind almost went blank again. You squirmed in his grasp but made no effort to pull away. In fact your body steadily relaxed back into John's grasp as you once more surrendered to his care and love.

"Wait." You begged, when John finally pulled back to get another lung full of air. "Wait, wait wait! Our twenty minutes are up you don't need to keep kissing me anymore."

"Your twenty minutes of being an omega are up." John declared as he suddenly rolled over and pinned you to the bed as he loomed over you. "I never said I would stop trying to convince you to be an omega after those twenty minutes. In fact I'm pretty sure I can't stop yet. You need context after all. You need to experience this as a beta so you can see how much better it will be as an omega. There's no way I'm done with you yet."

"But I'm a beta." You protested. "I'm straight."

"I fell in love with you when you were a beta." John pointed out. "I would love you what ever you are. Being an omega is what is best for you, since I can make you feel the best while your like that. But I can also make you feel so good as a beta that you'll completely forget about silly things like being straight or not."

With that John pinned your hands above your head with one of hands while his other massaged your neck and held your head in place so he could resume kissing you. There was nothing you could do to resist him. As a beta you were a lot less submissive than you had been as omega, but you still were no where near assertive enough to stop an alpha's advances. And frankly you didn't really want to.

You enjoyed having him in control. When you first picked up the rulebook all the possibilities had overwhelmed you. That was way more power than any one person was meant to have. How could you be responsible for everything that happened in the world? But now you didn't have to be. Someone else was in charge now. You could trust him since you knew he loved you, and he had proved that love by taking care of you, listening to your concerns and always acting in a way to give you greater pleasure. You were happy to surrender to someone like that if it lead to situations like this.

Once John felt you relax under his grip and give yourself over to his control, he stepped things up a notch. His knee came up between your legs, pushing them apart and putting pressure on your crotch. John's shirt was still large enough to cover you, even at your larger beta size, but it had gotten twisted up as you shifted around on the bed so now it had been hiked up a bit exposing your cock and ass to the air. The insides of your legs were still soaked with all the slick that had leaked out of you while you had been an omega preparing your ass for hot alpha sex. In fact quite a lot of that slick was still inside of you, it made your but feel squishy, soft and pliant and the muscle relaxants in that slick continued to ready you for penetration.

"Ah!" You gasped as the very edge of John's knee **** your rose bud to open up just a little bit, as your legs spread apart and your but cheeks were pushed open. Your body twitched upwards as the stimulation made your squirm, which in turn made you grind your dick against his thigh.

"There's a nice pretty noise for me." John growled possessively which made your heart flutter. "Let's see if we can get you to make that again."

He did so embarrassingly easily. Just by pressing his leg forward a bit it was like he had stepped on a gass pedal. You couldn't stop yourself from rutting against his offered limb. Your little dick felt wonderful thrusting and rubbing against him, your ass felt even better as it squelched and spread itself out against that column of muscle. You could feel yourself getting closer and closer to a mighty climax. It was wonderful, it was glorious even. And then it stopped.

John pulled his leg back and put a hand on your pelvis pinning it in place. Just seconds before your released it suddenly all ended. It practically gave you whiplash. You soon whined in protest.

"Sorry I had to stop you." John answered your wordless complaint. "I promised you we wouldn't have sex, so I can't let you climax right now. Don't worry I'll make you feel really good again in just a second."

You were struck dumb by the incredibly evil man who suddenly stood before you. A small sense of dread crept through your mind as you realized what was about to happen. He was going to edge you. He had gotten you so worked up and made you so helpless in his gasp that was nothing you could do to stop this. There nothing you could to stop him from dragging you up to edge again and again just to deny you the release you needed. You tried to protest, but were caught short as John's hand suddenly wrapped itself around your cock and started jerking you off.

"I wonder if your transformation powers work properly." John pondered aloud as you fell apart beneath him. "It seems like you still have an omega dick right now. Not that I'm complaining mind, I think it looks so cute wrapped up in my hand like this."

He released just before you started twitching for release. As you cried in frustration, John pulled his shirt over your head and wrapped your hands up in it before tying them to your head board. With both of his hand free, John resumed jerking you off while his other hand began to trace fingers around your entrance.

"You have such a greedy hole down here." John commented. "It's practically winking at me, trying to open up so my fingers could slip in side. This definitely isn't a straight man's ass. This is a slut's ass waiting to awaken to a whole new world of pleasure. I think if I slipped anything into it you wouldn't be able to live with it being empty ever again."

Another almost orgasm. Another sudden break. Then your ass was being lifted up into the air so that John's tongue could have a go at your rose bud. He only rimmed you though, he didn't push his tongue into now matter how you tried to thrust your hips back into him. The growing frustration and desperation in your mind almost blinded you to the fact that this time you came closer and closer to orgasm without any actual direct stimulation on your dick. He set you back down again just when you practically felt the sperm starting to amass in your urethra.

"Good God in heaven you taste wonderful." John said reverently. "A man might not be able to live by bread alone, but I could starve happily if all I had to eat was you."

"Alpha! Please!" You whined desperately in your best impression of your omega voice, just as John began to press you dick flat against your stomach and grind it back and forth between his palm. "Please let me come! Please give me some release."

"But you made me promise." John teased.

"I was wrong!" You gave up and released him from his word. "I should never had tried to hold you back. I should've trusted you from the beginning. Please take care of me alpha. Please do what ever you have to to make me come."

"You want me to do anything?" John said as he leaned in close and filled your vision. Which meant you failed to notice when he finally undid his own pants and pulled himself free of his underwear.

"Anything!" You begged in whined. "Just make me come, that's all I ask."

"And whatever my love asks for I will always give." John promised, as one hand easily stroked back up to the edge as the other lined himself up. "Omega, beta or even alpha, I will always take care of my precious, beautiful, perfect Tom."

With one fluid thrust of his hips, John sunk himself into you. The sudden intrusion made you tense up, but the slick and spit that had collected with in you allowed him to slide into your depths. At first it hurt of course, you had never had something go up that way, and John's dick felt absolutely massive. It left you shocked and gasping for breath. But once he was in deep enough he all but crushed your prostate beneath his unrelenting thrust. Lightning shot up your spine, your vision all but whited out, your gasps of pain turned into screams of ecstacy, and you weren't just pushed over the edge, you were shot over from a cannon.

Your dick exploded with enough **** you swear you felt cum hitting the bottom of your own chin. Four, five, six shots of spunk came out of you at the very least as your chest and belly were left a sticky mess. And your ass clamped down so hard around John's dick that the alpha actually had to stop driving into you to ride out the spasming muscles. It all went on for what felt like minutes and you were soon left a panting **** mess. As your vision finally straightened out you focussed on John's face which looked both extremely satisfied and also worshipfully in love with you. The sheer hunger in his eyes was almost concerning, but mostly it made you feel wanted and loved. It was a perfect moment. It ended when John next spoke.

"For a straight guy you sure do come really quickly once there's a real dick in you." John noted.

"Shut up." You protested. "You edged me so hard I probably would've come if you glared at me hard enough."

"Why do you have to be so stubborn about this?" John complained. "I think I've had enough of these, 'I'm straight' protests. I've always known there was a real cock slut living secretly deep inside you, I think it's high time I woke him up by dicking you until you can't think straight."
