Seana and Kelle could have been named for snakes. As they passed into their teens they shed their innocence like a snake does his skin, and they were also lustful and crafty and hyper. Their mother Brithana never neglected a chance to initiate the girls into Celtic rituals. Trevor, the large black Alsatian dog, had raped their cherries from them while she (Brithana) vibrated herself to a shrieking orgasm. Since their vaginas had been opened by the uncaring beast, Brithana kept sticking things up inside her children's cavities. She was gratified to see the first hairs of womanhood now appearing on their fine young pussies. Because Seana and Kelle, due to the sex and non-stop porn on loud display on every large-screen TV, were always feverish to cum, Brithana also bought them two snakes--Gyo, who was very large, and Neito, much smaller, but whose tail or head could be introduced up into the girls' vaginas or rectums. It was fun to see the children's surprised faces change as they felt the animal twisting violently inside them--they knew they would cum hard from this action, and assisted it with their fingers.
One morning Mom dragged a large metal stanchion of welded pipes into the sex area in the living room. She placed a sturdy covered box on the floor, and explained to the naked children that she was to be strapped with her four limbs like a cross--wide apart--and that the children should then introduce the stubby tail of Gyo, the huge snake who was in the box, deep up her shitter, and let him "make sacred" that channel so it could receive any animal cock. Brithana told the children to leave Gyo in "a good long time." Then the kids lashed their mother's wrists in place as she had told them, and lightly lubricated her hole. The children looked at each other and smiled. Then they whispered together, and giggled.
"Ok, put that fucker in my ass!" shouted Brithana.
Her daughters hauled out the hissing snake, collared its long, stubby tail, and gauged the weight. They they put the tip of the snake's tail to their mother's puckered asshole and little Kelle held it ready. Without warning, Seana jammed the snake's tail in deep, deeply fisting her mother who started screaming.
The furious snake began twisting. Seana guided it to the box, where it flipped and coiled, the rest of its length in the pretty sodomized young mother.
"NO, God, Seana, it's too big! Get it out! Get it out! I can't take the thickness! Please, Please....can't you hear me? Ah...Ahh....
Seana pumped the snake in deeper and giggled. She liked screaming. Liked pain.
Kelle stood in front of her mother's terrified face, watching it passively, as she blurted out, "God I can feel the dark God! HIs whole prick is up my ass! Girls, please please.
Then Kelle said, "Eat me out. Maybe we'll take the fucker outta your ass, you cum sucking whore, mama."
Kelle pressed her pussy lips to her mom wo licked them as hard as she could. The snake twisted in the mom. Suddenly Brithana--over-stimulated--began to piss, a long arc of pee. Seana got underneath it and drank some good warm yellow mommy piss, then spat it on her mom' face as she ate her sister out and sobbed for mercy.
"Suck on Trevor's prick, and we'll let you go."
So as Brithana was violated, she accepted the dog's penis. It eventually squirted pre-cum, of course, then it gave a huge load of good white sperm. Brith ate it. Then Brithana dropped her head, totally violated. Kelle scooped up some dog cum and spread it on her mom's face, her hair tangled, full of perspiration and sperm and kid-cunt-juice. Only then did she feel the snake slowly extracted from where it belonged.
