In Dunk's defense, Aerion did look and act like a very experienced omega. He was the one that had seduced Dunk in the first place; otherwise Dunk, as a lowly alpha hedge knight, wouldn't have been able to pursue a highborn omega that fierce and beautiful. It all had started with a kiss. When Dunk was on his way back after discussing the joust with Prince Baelor, Aerion had stolen a kiss from him in the hallway and simply left, leaving Dunk dirtying his own hands fantasising about those pretty lips the same night. And now, he was in the princeling's plush bedchambers, about to realise those fever dreams.
“Come here.”
Aerion was sitting on his bed, wearing a long velvet robe, the colour a red as deep as blood, and nothing inside. His silver hair shining in the moonlight, a pink nipple peeking through - what a sight, Dunk thought. There was a reason even the Kingsguards were calling the princeling a pretty little thing; he was very pretty indeed.
As Dunk carefully sat his giant self on the bed, following the order, Aerion pushed him on his back and straddled him. Dunk just let those small hands move him as he liked, feeling his cock stiffen already.
“Now disrobe me,” the prince whispered in a surprisingly sweet, sultry voice, making him get even harder. Dunk obeyed again with trembling hands, thinking how pathetic he would look in Aerion's eyes. Then he asked, swallowing hard, “What would you have me do now, my prince?”
There was a devilish smile on Aerion's soft, pink lips. “Fuck me.”
Dunk growled, grabbing the prince's thin waist and rolling him over to get on top of him. He spat on his palm, rubbed it against Aerion's cunt and found it soaked. He knew that his own manhood was, well… extraordinary, but surely an omega this experienced and wet could take it without any problem.
Dunk took his cock in his hand, lining himself up and nudging at the entrance before he pushed in with restrained force. It was then that he realized something was wrong, the omega was just too tight, he almost heard a sound of skin breaking.
“It hurts, it fucking hurts, slow down-” Aerion cried, clawing at Dunk's forearm. Seeing his pretty eyes well up, Dunk pulled out immediately and saw a red stain on his cock. He quickly checked Aerion only to find more blood between his thighs. Shit. He froze in fear, not really because he had hurt a royal and was about to be accused for treason, but because he wouldn't forgive himself for hurting such a lovely omega.
“You didn't have to stop. Just slow down and it would have been fine,” Aerion said, surprisingly not mad at all, his voice still teary but clearly trying to act all tough.
“But you are bleeding, my prince.” Dunk replied, afraid that he might have torn Aerion up. The prince looked so slight beneath him, with his soft, pale skin and narrow hips.
“That's quite normal for the first time. You didn't even know that?” Aerion replied, sounding almost irritated.
Dunk lost his words. The first time? Of course he knew that omegas usually bleed during their first times, but that meant he had just tried to stick his giant cock inside this virgin omega with a small build without any proper preparation. He felt like a monster.
Dunk's brows furrowed. “My apologies. I just never thought that you would be…”
"Be what, a virgin?" Aerion huffed. “What do you think I am, a common whore? An omega of royal blood should never be sullied before marriage.”
Dunk couldn't help himself asking, “But… you're okay with me sullying you?”
Being sullied by, and taking a risk of carrying a seed of, a lowly hedge knight. Aerion was the only omega princeling in the royal family, and a very pretty one at that. Despite his notorious temper, his hand was one of the most valuable things House Targaryen had to offer.
Aerion's face dropped in a second. “Shut up,” clearly upset, he tried to kick off Dunk's bulk of a body with his coltish leg. “I'm not in the mood anymore. Clean me up and go ready my horse.”
“No, please, let me make it up to you, my prince.” Dunk said, desperately, while holding both aerion's legs in place with one hand. He tried not to put too much pressure on them, lest those delicate bones break.
“What, how would you-” Aerion's words were cut short as Dunk spread his legs wide open and started to lick the blood smeared on his inner thigh. His breath soon hitched with anticipation; Dunk knew that the prince liked it. As Dunk's tougue swept the wet, delicate folds of his cunt, Aerion grabbed and tugged hard at Dunk's dishevelled hair, which didn't feel painful at all since his hands were so dainty and small. The omega could do no harm to Dunk with just his bare hands.
“Oh fuck, seven hells,” Aerion was practically crying by the time Dunk pushed his tongue inside him. The prince's voice was not all high and soft like other highborn omegas', but it sounded quite innocent and boyish, which spurred Dunk on. He doubled his effort, accidentally making the tip of his nose rub against Aerion's swollen clit. Aerion cried out, his lean thighs stiff on either side of Dunk's head, trembling from shocks of his orgasm. It tasted so divine, Dunk couldn't help but wonder if any exotic fruit from Dorne would taste this good.
“Easy, my prince,” he lifted his head and cooed, inserting two fingers in while kissing the tender skin of Aerion's lower belly. He was still so tight, barely accomodating the two fingers but to be fair, Dunk's hand was almost twice as big as his. Dunk worked his fingers in slow, steady rhythm, careful not to tear the fragile skin again. Soon he found the spot that made the omega gasp and whine helplessly, and then he pressed down hard. Aerion came for the second time that night, and Dunk enjoyed the feeling of his slick folds clenching around his fingers, but he had not expected Aerion to kick him in the face as soon as he regained his strength.
“Why… why are you so good at this?” Aerion sounded embarrassed at first, then his voice turned to bear more malice. “Which whore from the Flea Bottom has taught you-”
Dunk sighed. The prince was a very jealous type, that he had known from the start. It was quite lovely, flattering even, unless it got too much.
“I just wanted to make you feel good.” He said, pressing a kiss on Aerion's lips in an attempt to calm his fierce little omega. Aerion seemed like he wanted to snap some more, but as Dunk's thick flingers slipped back out of him, the only thing he could do was trembling as the head of Dunk's impossibly huge cock pressed against his wet entrance. “Relax, it'll feel much better this time,” Dunk whispered in Aerion's ear, repressing his own eagerness, concentrating on just how to make it fit. There was a loud, desperate gasp when his cock finally breached him. Fuck, Aerion was so painfully tight even with all the preparation.
“Is it okay to continue?” Halfway in, Dunk asked in a worried voice. He wasn't sure; he knew all the basics but still wasn't a master in this field like Ser Arlan.
“Well, yes, it still hurts… but bearable.” While panting, Aerion still had a few tear stains on his face and Dunk kissed along them, pushing all the way in. He let out a guttural groan as Aerion whimpered. It felt wonderful, the prince's cunt completely wrapped around his cock, all warm and soft unlike his temper.
“Can l- can I move now?” He asked for the permisson again, which clearly annoyed Aerion, who clawed at his shoulders. “Gods, just shut up and take me as you want, idiot.”
And so, Dunk did as he was told. He fucked into Aerion's lithe body, tentative at first, but then setting a more brutal pace to take his own pleasure. And at some point- “Oh,” Aerion let out a shaky moan, clenching down hard. Dunk's enormous cock was hitting the back of his channel, practically trying to get into his womb, making him cry out and beg. His soft arms were wrapped around Dunk's neck, pulling him in closer and for Dunk, it felt like a slice of heaven.
“You're taking me so well, my prince. Yes, be good for me, just like that…” He murmured, knowing that Aerion was weak at compliments. Those words made him, if only for a moment, nearly sweet and docile. Gods, Aerion's flushed face looked so innocent and pretty, Dunk would never let anyone else see it. He had never been a religious man but he thanked the seven gods for this gift that he felt he didn't deserve. He was the first to take this arrogant, perfect omega and would be the last, too.
“Do it inside me,” Aerion plead, his wet amethyst eyes staring up at him, as Dunk sped up his thrusts, getting close to the release. He looked so vulnerable like this, it made Dunk's chest ache. “What?”
“I want to feel it, fuck, I'm ordering you-” The prince sounded delirious with pleasure, his hot folds tightening around Dunk's girth. “Please.” And it was that single pathetic word that finally made Dunk lose his mind. He nearly folded Aerion's small body in half, while still being careful not to grab his thighs too hard, then fucked into his cunt mercilessly. It took only a minute or so for Aerion to come with a shriek, and Dunk followed him right after. As he spilled inside him, he kept whispering in the prince's heated ear; you are so beautiful, you feel like heavens, fuck, I don't deserve this.

After Dunk finished cleaning both their bodies with a wet cloth, there was an awkward silence. Aerion was slumped like a rag doll on the bed, clearly not in a mood to talk. But Dunk had to talk to him about it- he might have just planted his seeds in a fucking Targaryen womb.
“Are you intending to drink the… tea in the morning?” Flea Bottom didn't really have a safe way to avoid pregnancy, omegas there would just chew on some herbs that were used in whorehouses and risk their lives. But highborns had the maesters' tea, that he knew.
Aerion snorted. “That is none of your concern. Even if I bear a child, you will not be responsible for it.” His words stung a little. Dunk's hand caressed the soft skin of his belly. “But I want to, if you would let me.”
“Nonsense. You are not my husband.”
“I would ask for your hand after I gain the status suitable to be your alpha.”
Aerion looked offended, his pretty silver brow furrowed. “Wait, if it is about protecting my honour-” Dunk quickly placed a kiss on his nape. “No, it is not just that,” then he mustered up all the courage he had to say, “I want you to be my omega. Mine.”
“How insolent. I am your royal prince,” Aerion snapped, but there was no real malice in it this time. “Now shut up, I do need some rest after enduring your brutality.” He rolled onto his side, turning his back to Dunk, but Dunk could swear that he saw the pale skin of Aerion's neck all flushed red.
It made him smile.
