Ethan flipped the white-haired succubus over and whispered in her ear, "Didn't you reject me so coldly before? Why are you begging for it now? Are you just a little slut who needs to be fucked? Huh?"
He punctuated each word with a heavy slam of his hips.
"Ohhh... I love... I love Master Ethan's cock..."
Ethan looked down at the debauched Lucia and thought of her mother, Chisato. "Call me Daddy!"
"Nngh... Daddy! Daddy! Your slutty daughter... loves Daddy's cock! Only Daddy's cock can make me feel this good!"
Lucia offered no resistance. The taboo words fueled Ethan's fire. In his mind, Lucia was becoming Chisato.
"Since I'm your Daddy, it's only right that I fuck your Mom too, right?!" He hammered her cervix, making Maria roll her eyes. Ethan's intentions were as clear as day.
Lucia hesitated for a second, fearing her mother's anger, but the succubus instinct won. "Yes... it's... only right..."
"Yes what?" Ethan pulled her leg further to the side to drive even deeper into her womb.
"Yes... you are my Daddy... so fucking my Mom... is right!" Lucia moaned, completely broken. "Good Daddy... fuck Lucia more... my pussy feels so good..."
Ethan wasn't done. He grabbed her chin and forced her to look at the mocking Maria. "Look, even your little sister looks down on you. The 'cold' Lucia is actually a perverted nympho."
Lucia tried to speak, but the pride of an elder sister was gone. Ethan pulled out until only the head remained at her entrance. The sudden emptiness was agonizing.
"Tell me, are you a perverted nympho?"
"Please... the cock... give me the cock..." Lucia begged, grinding her ass against him. "Yes... I'm just a lowly, perverted nympho succubus... oh god... it's back in... so good!"
"Good daughter. Let Daddy give you what you want."
Ethan thrust with renewed vigor, his massive head battering her cervix. Lucia was in paradise. "Daddy... fuck me... kill your slutty daughter with your cock!"
Ethan grabbed her waist and forced her into a kneeling position, hammering her from behind. Lucia's white body shook like falling snow, her breasts and butt swinging wildly. The dark dragon invading her white flesh was a masterpiece of desecration.
"I'm coming! Daddy! Your cock is too good!"
Lucia gave up all dignity, screaming as her body tightened and a massive wave of juices sprayed out. She climaxed right in front of Maria.
"Lucia, Daddy's going to cum now. I'll fill your womb and make you give me two succubus cauldrons just like your mom did, okay?"
"Yes... Daddy... cum inside me... I'll give you whatever you want..."
Ethan drove deep, his burning dragon hitting her cervix as he pumped gallon after gallon of thick, white essence into her. He stayed inside for a moment, his hips bumping against her snowy cheeks.
"That was amazing..."
He pulled out, a long white string connecting his shaft to her leaking flower hole. He pulled the exhausted Lucia into his arms, their naked bodies pressed tight. His dragon was already starting to stir again.
Ethan squeezed her breasts. "Lucia-nee's body is incredible, just as good as Maria's."
Maria looked at her respected sister lying helpless in Ethan's arms and felt a twinge of envy. "Hmph, I can transform! Two forms are better than one!"
Ethan laughed, kneading Lucia's breasts harder as his dragon pressed against her rear, making her moan like a kitten.
