Valarr Targaryen was your husband in name, in oath, in every careful arrangement the court had signed and blessed and dressed up in silk to make it look like peace after the Blackfyre rebellion. Peace, if one chose to believe in such fragile things.
The realm had not healed so much as it had learned how to limp forward without drawing attention to its wounds. Even in the Westerlands, where House Lannister stood unbroken and gleaming in name, there were fractures no amount of gold could fully polish away. House Reyne and House Lefford, once sworn bannermen and trusted shields at the edge of Lannister pride, had bent their banners for the Blackfyre cause when it mattered most.. and everyone remembered. The crown remembered. The Westerlands remembered.
After all… what did Lannisters always pay? Their debts. You were that debt, you had been folded into that tradition as neatly as coin pressed into a palm.
Your sweet lord husband… he never looked at you like a cage. At some point he truly began to feel love for you, he may not have bedded you often because of duties and schedules, but he’d wake you late in the night. Placing soft kisses along your neck, when he felt you smile he’d whisper sweet praises in your ear. How well you preformed for the court, what a great queen you’d make, and oh gods what a great wife you were to him. Even the word wife began to feel insufficient to him, he’d quietly worship you in private.
What did he do to deserve the gods blessings to get a wife like you?
There was just… one problem, it had been a year and you were not with child yet. Your goodfather Baelor brung it up several times during private family dinners with his family and Maekars brood present. It would earn a dismissive wave from Valarr, a sigh from Maekar, Daeron drowning further in his cup, and… Aerion. Oh Aerion loved the subject, he’d go on and on about how his seed would take root in such a supple bird from the West.
At first, you would blush and ignore the comments, finding Valarrs hand beneath the table and squeezing it. He would return the small intimate gesture for a fleeting second before masking his princely attitude back and continuing the dinner.
One night.. you had enough of Aerions rants and Valarrs dismissiveness…
“An heir would do you good, son.” Baelor slipped in after Maekar excused himself from the table to tend to his youngest daughters.
Valarr stabbed the meat on his plate harsher than needed, “I do not wish to discuss this at the table. My duties for the court and realm come—“ but he was quickly cut off by Aerions boasting.
“True dragons seed would root quickly if she were my wife,” Aerion grinned into his goblet, his eyes watching you over the rim as your gaze met his, “I think the Kingsguard would have to pry me off—“
Valarr slammed his fist down on the table, that was the only crack in his posture before he quickly reset it, “That is enough Aerion. You will find your own wife soon enough and start your own family.”
“Or i could take yours, seems you cannot bed her enough. I have a hearty amount of time on my hands, cousin. Just send her to my quarters and you’d have a heir in a matter of weeks. Perhaps days.” Aerion tilted his head setting his goblet down with an amused smirk.
Aerion was always full of glee when he could provoke Valarr, you were the only soft spot he had after all. Your head spun with anger, before you knew it you were speaking out loud.
“I believe my lord husband will bed me so many times tonight that my belly will practically swell with his seed.” You chimed in, Valarr froze, a blush spread from ears to his cheeks in the matter of seconds.
Daeron choked on his whine and beat at his chest as he hunched over in his chair. Aerions head was still tilted, but he didn’t look too amused anymore. You never spoke out of turn, and for you to say something so vulgar, at the private family dinner. The two of you fell into a quiet staring match neither seemed willing to lose, until Valarr firmly grabbed your arm, pulling you up.
“Excuse me father, I believe my wife is feeling unwell.” He said matter of factly, Baelor gave a quick simple nod without looking up.
“Off to make an heir, cousins?” Aerions voice sounded deeper than usual, his eyes were still locked onto you, even as you looked away and followed Valarr out. You could feel the heat of his attention on you until the door shut behind you.
The walk to your shared chambers was awkwardly quiet and tense. You had never seen Valarr quite this upset before… or perhaps embarrassed?
When you reached your chambers he more or less shoved you in, when you had the guts to look up at his face, it was still beet red.
“Im sorry—“ the words fell short as Valarr raised his hand up to cut you off.
“Do not,” he sighed, “what in the seven hells possessed you to say something so improper in front of all of them? I’ve told you time and time again to ignore his comments, Birdie.”
“Truly, I am sorry Valarr.” You pleaded, but all of your desperate begging did no good.
He quickly left the chambers and you felt how his absence was heavier than his presence in this moment. It shouldn’t have hurt so much but it did.
That night you lied alone in the canopied bed, listening to every footstep outside the door, sleep came fitfully but it finally grew on you in the late hours of the night.. only to be woken again, but it wasn’t the soft whispers or kisses Valarr usually woke you up with. It was a persistent hungry kiss, on your thigh, on your hip, on your abdomen, then something wet trailing up to your collarbone.
“My love?” You whisper, your eyes still not fully opened.
“No, but I will make love to you.” A deep rumbling voice whispered against your neck. Your stomach churned and twisted as you slowly realized whose voice that was.
Before you could put up a fight, Aerion had grabbed both wrists and pinned them above your head as he came face to face with you. His tunic unbuttoned and hanging open loosely, no smallclothes underneath. Just the bare, hard plains of his chest. His mouth twitched as he stared down at you.
“This is wrong! This- this is- against LAWS!” You shouted in a trembling whisper.
“Careful, little bird. You’ll tire yourself trying to think like a man.” Finally his mouth twitched into a sadistic smile at his condescending praise, “You look prettier when your mouth is shut, but perhaps I’ll let you open it while I spill my seed in you so I can hear the sweet noises I’ll draw out of you..” just as he finished speaking, he let go of your wrists and flipped you over, that’s when you noticed your nightshift was already bunched up to your chest, you tried to push it down but your resistance was met with a sickening rip of fabric. He was tearing the nightshift off of you, and just as you began to yell out for him to stop, he shoved your face into the pillows and held your wrists in a new possessive position on your back.
The sound of his belt being loosened and the rustle of his trousers could be heard clearly. Your muffled sobs and pleas only fueled him more as he spit in his hand and lubed up his cock. A wet a squelching sound rang out in the chamber as he roughly jerked himself off, knees on either side of your hips.
“No need to pout. You know I will indulge you more than anyone else ever would.. especially your lord husband. Does he not satisfy you, cousin?” He asks but pushed your face further in the pillows so you could not respond. The throbbing tip of his cock nudged at your thighs, parting them as he deliberately took his time slowly working himself inside of you. Once he was almost halfway, he spit in his hand and lubed up further so he could sheathe himself fully.
“Seven- hells…” he groaned out trying to push any inch of him deeper. He ignored your struggles, only gripping your wrists tighter in his fist as he began his painfully deep thrusts making you scream into the pillow. The sound of skin hitting skin echoed in the chamber, it felt as if your stomach was coiling, tighter, and tighter. This odd sensation began to build in your lower abdomen, your cries and screams soon turned into desperate moans for something you could not grasp yet. A wave of sickening shame fell over you like a blanket, you loved your sweet husband, how could you be enjoying this? Why was Aerion making you feel so good? And what was this feeling?
“You poor little thing…” he sang as he tirelessly pounded into you, his body slick with sweat, his skin stuck to yours as he leaned further down. His lips so close to your ear that it gave you goosebumps.
“Does he make you feel this good?” He questioned you as he let your wrists go, a part of him wondered if you’d push him away and fight back… but you didn’t. Your hands curled into the sheets, your nails screaming against the fabric as you screamed into the pillow.
“Your belly will practically swell with my seed, sweet songbird..” he teased into your ear as he fucked you, “Did he… fuck-“ he panted, nipping at your ear, his pace never faltered yet his words did. A sharp stinging pain bloomed on your ass when he slapped it. Perhaps to make you forget how he couldn’t finish his words because your cunt felt so good wrapped around him.
Make you forget, it did. Because a sudden warmth flooded you, that’s when you snapped, climaxing without even knowing what it was. For one terrible moment, the shame left your body entirely, replaced by a dizzying ecstasy that scorched your mind blank. Aerion found it fascinating, you could feel his grin as he fucked you harder, a half groan, half laugh escaped his lips as his pace stuttered while he came inside of you. His hand curled in your hair, shoving your head down so hard you almost couldn’t breathe.
He laid on top of you for what felt like hours after, bodies slick and warm. Pants coming from both of you, the humiliation brought you back to reality as he pulled away from you.
“The unfortunate thing is that I enjoy your attention in every form, I desperately hope you’ll think of that for weeks to come. until you come to my chambers begging for me to please you again.” His back faced you as he dressed himself, finally you took your head out of the pillow.
The sight of him dressing in your shared chambers like he was meant to be there left you dizzy. Yet you could not look away, he gave you something Valarr hadn’t… a release you now longed for… a release only Aerion could give you…
His words replayed in your head after he left, almost as if he branded you personally.
Oh how you were a poor little thing, desperate and needy for him to fuck you again. Until you could not form a coherent thought other than his cock pulsing inside you. His hot seed spilling out of you and him fucking it back inside so it takes root. So you give him an heir. With white hair and lilac eyes, a vision of Old Valyria…
