Chapter Text
Cersei watches as the younger Lannister daughter damn near drapes herself over Lord Umber. Smalljon Umber, the man her son had picked for his aunt to possibly marry. The Lord was clearly enjoying the attention the beautiful girl was giving him, popping his chest out like the rooster who got the hen. While the scene angered Cersei, she had to admit, (Y/N) Lannister was a fantastic liar. The girl hung on every word Smalljon spoke, staring up at him with doe like eyes, faking an innocence that both Cersei and Jamie knew was not there. Everyone besides the two eldest Lannister siblings would think she was already madly in love with Lord Umber. That is what angered not only Cersei but Jaime the most. They can’t mark their little (Y/N) to ward off potential lovers.
“Bring my lovely aunt over here, Dog.” Cersei looks over to see Joffrey point towards (Y/N) and Lord Umber.
She watches as The Hound walks over to the two and grabs (Y/N)’s arm gently while speaking and leads her to the head table. Cersei glances towards Jaime to see him give Smalljon a nasty look as his eyes drag up and down their little sister’s body. The Queen Mother looks at her sister with a small smile as Sandor lets go of her arm and moves back to his post. (Y/N) smiles and bows slightly to her nephew.
“You needed me, My King?”
Joffrey leans forward to look at his aunt closely. “Are you having fun with Lord Umber?”
“Why of course. I thank you so much for allowing him to potentially be my dear husband.”
“Never say I never did anything for you, Dear Aunt.” Joffrey looks past the woman’s head before standing up, “excuse me, my betrothed is here.”
The two Lannister sisters watch as the young king walks off towards Margaery before looking back at each other. Cersei notices how the eyes that were once full of fake innocence and love were filled with true love and longing. She is sure her eyes hold the same look as she looks into her younger sister’s eyes, the same eyes she has seen roll back as their beloved brother fills her womb with his seed, the same eyes that stare up at her from between her legs. Cersei swallows while looking down before looking back at her sister.
“You seem rather comfortable being all over Smalljon Umber.” Cersei’s words came out far more venomous than she would have liked.
(Y/N) sighs softly and looks back towards Umber, giving him a smile before turning around. “Cersei, you know I have to act like this. Do you think I want to marry this man? Because I can tell you now Sister, I don’t. I want nothing more than to be in my lovers’ arms and to show the rest of Westeros that I love them, but I can’t.”
Cersei closes her eyes as she sees the sadness fill her secret lovers’, only to open them again as she hears the clinking of Jaime’s armour. The two Lannister females look to the side to see their brother stopping beside them, giving the two a charming smile.
“Everything okay over here?”
Cersei looks down as (Y/N) looks at her again, “yes, everything is fine. I was telling our sister that I wish I didn’t have to drape myself over Lord Umber after she had gotten a bit jealous.”
Jaime laughs as Cersei’s head snaps up to give her sister a glare. “I was not jealous. I know you belong to Jaime and I.”
“So you wouldn’t mind if I go back to him and continue rubbing against his side?”
Both Jaime and Cersei’s jaws clench as she smirks at them, showing them that they were clearly jealous.
Jaime reaches over and grabs (Y/N)’s wrist pulling her closer to him growling. “You are not going back over to him. You are going to bed, you have had too much to drink.”
It was a clear lie, Jaime just wanted an excuse to take her to her room and have his hands all over her body. The younger Lannister didn’t protest, letting her older brother lead her away from the crowded room. Once they were away from the eyes of others Jaime allows his hand to come and rest on the small of her back. As the need for each other gets stronger, they speed their movements up wanting to get to her room faster.
“Where are you two going?” They both try to not suspicious as they look over to see Tyrion walking into the hallway.
“Your twin sister had gotten a bit drunk.” Jaime lies easily to his brother.
Tyrion looks over at his twin taking in her flushed face, which he believes is from the alcohol. He laughs before walking away, knowing that he, his twin and their older sister are all huge alcohol lovers. The two secret lovers watch as their brother rounds a corner before making haste towards the girl’s room. As Jaime opens the door and lets (Y/N) in her room, he sees a servant watching the two. He holds a finger to his mouth before entering the room as well and shutting the door.
(Y/N) is undoing the strings of her gown as Jaime turns around, his eyes dragging up and down the back her body. He walks to her, his hands grabbing the shoulders of her dress, slowly dragging them down her arms. His lips fall to press gentle kisses behind her ear, moving lower to press open mouth kisses to her neck. She sighs and leans her head back to rest on his shoulder, her hand coming up to run through his hair. Once her dress is low enough, her dress falls down to the floor. Her bare body clear to the air and the eyes of her older brother, the same eyes she looks into through the mirror in front of them.
Jaime’s hands come up to grab her breasts, “so beautiful. My beautiful,” he gently bites her neck.”Stunning,” he presses his head against hers while staring into her eyes. “Little sister,” his fingers pinch her nipples.
(Y/N) lets a little whine slip through her lips as she pushes back against him, feeling the tent in his trousers against her bum. Jaime’s hand slide down to her waist, pulling her back against him while turning her head to kiss her hard on the mouth. He lets her turn around her arms wrapping around his shoulders, him picking her up easily. As her legs wrap around his waist, he feels the wetness from her center. The idea of her being this wet purely for him and Cersei makes his cock twitch in his trousers. Jaime walks towards her bed, waiting for his knees to hit the bed before letting her go. The moment she is on the bed, he pushes her up towards the pillows while crawling on the bed.
She settles against the pillows looking into his eyes as he take off his shirt. Jaime places his hands on her knees before forcing her legs open, letting him look at her wet pussy. He gets to his stomach, having his face right in front of her pussy. The two Lannister’s stare into each other’s eyes as the eldest one leans forward to press a kiss to her clit. (Y/N) bites her lip as he opens his mouth and wraps his lips around her clit, sucking gently. She leans her head back moaning quietly as he continues to suck on her clit, his hand coming up to tease her opening. Jaime lets go of her clit giving it a lick before moving his mouth lower, bringing his hand up to gently rub her clit.
(Y/N)’s hand grabs his hair as she feels his tongue push into her cunt. She pulls him as close as she can, her eyes rolling back as she feels his tongue massaging her walls. His fingers pinch her clit as she grinds against his mouth. He continues fucking his tongue in her cunt as he feels her start to tighten around his tongue. Jaime rubs her clit faster as her moans get louder, letting him know she was close. As she cums on his tongue, he can’t help but moan against her pussy. Jaime continues thrusting his tongue in her twitching cunt until her hand goes slack in his hair.
“You two looks so good like this,” the voice of their sister fills the room.
The two look over at her, smiling as they see her already nude, her hand between her legs and her fingers slowly rubbing her clit. As Jaime stands up to take off his trousers, Cersei comes to the bed to lie beside her sister. The moment Cersei is on the bed, her lips find (Y/N)’s. Jaime stands there watching the two, his hand slowly moving around his cock. The two girls continue to kiss and run their hands up and down the other’s body. The throbbing of his cock becomes too much for Jaime as he walks back over to the bed. He grabs (Y/N)’s foot and pulls her down the bed making her squeal.
“I need inside our little sister’s sweet cunt.”
This makes both the Lannister girls moan. Jaime flips the youngest girl on to her stomach, lifting her hips up. As he teases her pussy with his cock, Cersei moves to have her cunt in front of (Y/N)’s face. Seeing her sister’s pussy, the youngest of the three latches her mouth to her clit. Cersei moans as she feels her little sister suck and lick at her clit, her hand coming to run through the girl’s long hair. The eldest girl lays back, her other hand coming to grab her breasts, only to shoot back up as the girl between her legs moans loudly against her cunt. Jaime is smirking as Cersei looks up, his cock buried deep in (Y/N)’s cunt. He stays deep in her grinding slowly, making her moan quietly around Cersei’s clit.
(Y/N) pulls away from her sister’s pussy whining,”Jaime please.”
“Please what, Sister?”
She pushes back,”please fuck me, Big Brother. I need to feel you fill my womb with your seed. Please give it to me.”
Jaime moans loudly at his sister’s words before slowly pulling out and thrusting back in. Her eyes roll back as she feels him fill her cunt with his cock, only to have Cersei pull her hair dragging her back to her own pussy. (Y/N)’s tongue runs up and down the lips of her older sister’s cunt, only to slide in to fuck her. Cersei moans and arches her back as she feels her sister’s tongue enter her pussy, fucking her in time with Jaime’s pace. The only noises filling the room are those of Jaime’s skin hitting (Y/N)’s, Cersei’s loud moans mixed with (Y/N)’s muffled ones and Jaime’s groans, and the quiet sound of (Y/N) eating Cersei’s cunt.
The grip Jaime has on (Y/N)’s waist is bruising, his nails digging into her hips. All the girl can focus on is the sweet taste of her sister’s cunt and the feeling of her brother fucking her pussy hard, his balls slapping against her throbbing clit. As Jaime feels his balls tighten, he pushes (Y/N)’s head down into Cersei’s cunt, letting him fuck her faster and deeper. The muffled squeals and moans of the youngest Lannister is drowned out by Cersei’s loud moans as she squeezes the tongue that is fucking her. (Y/N)’s body shakes as she tastes her sister’s juices, her own cunt tightening around Jaime’s cock as she cums. She continues eating Cersei out till she is pushed away, her moans now filling the room freely.
Jaime keeps pounding his cock into his little sister’s sensitive cunt, his eyes rolling back as he feels her squeeze his cock tightly. His balls draw up as he slams himself deep into her, grinding against her as he starts to cum. Cersei is whispering sweet words to her sister, who is whimpering at the sensitivity of her pussy. (Y/N)’s body shakes as she feels Jaime fill her womb with his seed, silently hoping she will be with child soon. Jaime stays inside her with his head against her back as he comes down from the heavens. He slowly pulls his softened cock out of her twitching cunt. Watching as his cum follows his cock out, dripping out of her used pussy.
(Y/N)’s body falls to the side once she was able to, her chest rising and falling with her harsh breathing. The eldest Lannisters curl around the younger one, encasing her between them. They both give her a gentle kiss before kissing each other, letting the youngest girl get comfortable and slip into a deep sleep.
“See I told you, I know you are Jaime and I’s.
