They fall silent

The two sisters fell silent then. Lucas waited a little longer, but then silently retreated back to the kitchen. He then retraced his steps, intentionally making his footfalls a little louder than they necessarily needed to be, announcing his return.

When he entered the library, Eldwyn hadn't moved, as instructed. She turned her head to meet his eyes. There was something about the sight of her that got to him. Her patient expression as she waited for what he'd do to her next; her arched back and his cum still glistening as it trickled down her crack; her red asshole, still not fully closed after he used her harshly; her soft little dick and tight sack.

She noticed his hard cock. She licked her lips unconsciously. "Are... are you going to fuck me again, sir?"

Lucas chuckled. "I guess I am. Are you ready?"

"I'm your whore, sir," she replied, confidently, her eyes shining proudly.

He had no answer to that, at least, not a verbal one. Instead, he knelt behind her for the third time that evening. He spat twice on her trembling hole, then put his cock at the entrance. He could feel her sphincter relax and he slipped in easily.

"Nngghh," she groaned, the friction against the raw skin sending tremors of mixed pain and pleasure up her spine.

Still tied, she had little room to resist him, but she didn't even tense, remaining totally passive. He wrapped his hands around her midsection and held her tight as he thrust into her. Her entire body rocked forwards with every thrust, groans and moans escaping from her lips as he used her. The sounds were music to his ears.

She was nearly a rag doll in his arms as he fucked her, his pelvis impacting against her ass so forcefully the fleshy globes were beginning to redden as if spanked, and her pained whimpers were climbing in pitch.

Lucas could feel her body tense and stopped moving, leaning forwards. "Are you all right? I can stop, if you want."

"No!" Eldwyn cried. "I mean... don't stop, sir. I can take it."

Lucas hesitated. She was saying what he wanted to hear, he suspected. He didn't want to actually hurt her... but then again, she did just ask him to continue, and he had to admit there was something very erotic about her accepting some discomfort or even pain to give him pleasure.

"As you wish," he whispered, "but tell me when it's too much, all right?"

"Yes, sir. Use... use me, sir."

With that simple statement of submission, he began thrusting into her, with long, slow strokes, pulling out almost all of the way, then pushing back in until his pelvis was flush against her ass.

Her chute felt just as good on his dick as it did the first two times, better maybe, the heat of the irritated flesh and his cum lubricating them both providing a unique sensation.

"Uhhhnn.... Nnngg... Ergghh... Mmphhnnn...!"

Eldwyn's cries rose in volume as he picked up speed. Her fists were balled behind her back in an attempt to endure his ****. He was embarrassed to admit it turned him on. If he'd had any doubt left, he put those to rest now. She was his, now. His very own Elven fuck toy, to use as he saw fit.

Leaving one hand on her hip, he wrapped her hair in his other and pulled, lifting her chest from the floor and drawing a cry of shock from her lips.

"Aiii!"

"Shut up, whore," he said through gritted teeth. "You wanted me to use you, so now take it like a good little slut."

Lucas lifted his eyes from the writhing body beneath him and found Kythril staring at them, slack-jawed. She was sitting cross-legged, gripping her lower legs with both hands and leaning forwards. She was so enthralled she didn't even seem to realize her body was completely on display.

Lucas grinned. "Do you want a closer look?"

Kythril snapped out of her stupor and looked away, blushing profusely and covering her body. However, try as she might, she could not keep her eyes from the performance in front of her.

"Sit over here," Lucas said.

She shook her head resolutely, but some other part of her **** her body into motion, getting onto hands and knees and crawling towards the spot Lucas had indicated, right next to Eldwyn.

"Talk to her," he continued, never once slowing his thrusts.

Her mouth opened once or twice, but no words would come out. She swallowed nervously.

"Eldwyn?"

Eldwyn looked over at her from beneath heavy lids. Her face was covered in a light sheen of sweat, and strands of hair stuck to her forehead.

"Nnnmmm..." the girl seemed to have lost the power of speech and just whimpered.

"Eldwyn, just... just tell him to stop." Kythril pleaded.

Eldwyn shook her head. "N-no. I... Uhhnnn... I can't."

"He's hurting you!"

"Nnghh... Ahhh, I'm all right. I... I want to do this."

Kythril reached out to wipe the matted hair from Eldwyn's forehead, but whatever she saw in Eldwyn's face made her eyes widen and she froze mid-movement.

After a long moment, she gave a minute nod. "I... I understand."

Lucas' movements had slowed while he followed the exchange, and now Kythril turned to him.
