Plenty

Squatting in front of Oberyn like a back-alley whore, Tommen/Tamara started sucking his cock with an apparent familiarity that saddened but didn't surprise Cersei at this point. Wrapping her ample, girly lips around his cock, she bobbed and slurped up and down just over half the length of it with ease. Grabbing the base of it with one hand, she gradually pushed herself a little further each time down his shaft. Oberyn quietly muttered his approval of the little painted whore gripping his cock between her fat lips.

"Hnggg, yes you little cock-slut. That's it. Remember what I taught you little girl? Slobber on it."

Doe-eyed and eager to please, Tommen pulled the thick cock out of his mouth with a pop. She pushed her finger back in her throat to gag herself and drooled all the resulting spit over the head of his prick. Placing both hands on the back of Oberyn's legs, she looked up at him with an unmistakable hunger, drool dripping down her chin.

"Fuck my face daddy. Use my whore throat like a pussy. I know I'm just a hopeless faggot daddy but I want you to treat me like a real whore" she barked at him. Cersei couldn't believe what she was hearing, but she recognized that voice in herself. It was the kind of voice she used when she wanted Jaime to be merciless with her. To her shock, she felt herself getting wet at the sound of it.

Without hesitation, Oberyn grabbed Tamara by the root of her hair and began cramming his cock into her mercilessly. She had done this so many times to so many different men that it was a challenge to make it too rough for her to handle. As he repeatedly pushed her former son's pretty little face down to the hilt of his cock, Cersei could see the bulge of his cock in her throat with each thrust. Tamara whimpered with unmistakable pleasure as he drooled uncontrollably over the cock sliding in and out of his mouth like a wet pussy. Cersei's hand migrated to her crotch, and she found herself savoring the sound of Tommen getting throatfucked.

Gluck-Glukh-Hlugh-Glugck-Hluckh-glugccccckkkhh----

Oberyn held Tommen/Tamara's head against his crotch, his dick pushing out against the inner passages of her throat. Tommen offered no resistance. Cut off from oxygen, her eyes began to roll back into her head.

"How does it make you feel Cersei, that if I wanted to, I could have your brainless bitch of a son choke on my cock until he suffocated, and he wouldn't lift a hand to stop it?" Oberyn menaced. Cersei tried to muster the will to stand up and fight back, but her body wouldn't let her. After what seemed like a couple minutes, Oberyn abruptly pulled Tommen off his cock. Coughing, gasping for air, her mascara running, and dripping spittle all over her silken hooker dress, Tommen/Tamara smiled. Her pathetic little dick twitched in excitement.

"The truth is the Tommen you knew is dead. In his place, he left this little slut."

Bending over the table where the decanter of wine lay, Tamara made sure her mother got a full view of her perky little bubble butt. It looked as fine as any of the ass that whores down in Flea Bottom were flaunting, save for the dick and balls tucked in between her legs. After taking another swig of wine, Oberyn strode over to his little butt-slut and started rimming her. Tamara's legs squirmed with pleasure as he masterfully stimulated her pert little asshole. She squealed like a giddy handmaiden and bit her lip in excitement for what was to come. Cersei's gave in to her conflicted feelings; she was envious of the greedy little whore who had been her son.

"Daddy, I need you in me. I want you to violate my little asshole. Just fucking tear it apart with that fat cock of yours." Tamara begged. Cersei began masturbating furiously against her better judgment. Oberyn rested his dripping cock at the entrance of Tamara's girly little boy-hole. He grabbed her hair and pulled her in close.

"I'm going to ream your little shitter you worthless cum-dump, and when I'm done breeding your faggot-ass, you're going to walk over there to your whore of a mother, and feed her my seed straight from your gaping fuckhole to her mouth" he grunted.

Tamara licked her lips. Horror and sordid excitement washed over Cersei in equal measure. With that, Oberyn rammed his hard cock past all resistance into Tamara's ass. She screamed in pleasure and undeniable pain. Even with all of her drool as lube, the taut ring of her asshole still gripped and contracted around his thickness. His pace quickened and with every thrust into her bowels she gave out a pitiful yelp. Tears began streaming down her face.

"Tell me" Oberyn said as he relentlessly pounded Tommen's ass, "and tell your mother: what the fuck are you? Just some desperate faggot? A little bitch who gives up his ass because he's worthless as a man? Or are you a girly whore deep down, desperate to be used by men like your whore mother?" Tamara began spurting cum over the tile floor as Oberyn degraded her the way she loved. He gave her ass a swift whack as his rhythm hit a steady, ever-increasing pace.

"You think you can call yourself a king?"

The full implications of Oberyn's revenge were made clear to Cersei now. Not that she could care; she was cumming at the thought of sucking his filthy cock straight out of her son's/daughter's ass. Struggling to utter a word as Oberyn ravaged her little fuckhole, Tamara/Tommen began to speak:

"I ... I'm not a king ... I'm a princess. Daddy's little princess."

Oberyn couldn't hold it any longer. His member buried to the hilt, his hot cum pulsed through her bowels in a torrent. By the time he was finished, he and Tamara were heaped over the table in a sweaty, musky mess. Without hesitation, Tamara stood up off his cock, which slid out with gentle *pop*, clenched her little boy-pussy, and walked over to her mother. Cersei had made herself cum twice now, and in her addled state of ecstasy she gladly slurped Oberyn's steaming load out of her own child's asshole. Cersei knew where Tommen/Tamara got it from - she was always an utterly filthy slut herself. Tywin wouldn't be happy about this, but she could learn to live with it.
