Take charge

Lucas took charge. When she wasn't looking, he took three quick strides over to Eldwyn and swept her up into his arms. She squeaked as her feet left the ground, then giggled with delight before Lucas smothered her by pressing his lips against hers. Though her eyes were still wide in surprise, she wrapped her arms around his neck and parted her lips, eagerly letting him explore her mouth with his tongue.

When Lucas broke the kiss, she stared at him breathlessly, her cheeks tinted with excitement.

Lucas spoke quietly enough that Kythril couldn't make out the words. "You surprised me back there, pet. Don't you know how nasty it is for you to want to do this with your own sister?"

"I... I'm just curious."

"You might be able to get Kythril to believe that, but I know you better than that," Lucas said, chuckling under his breath. "And even if I didn't... I can feel your cute little dick poking into my hip."

Eldwyn struggled in his grip, but Lucas tightened his arms around her and wouldn't let her squirm free. He dipped his head down to lick and suck on her neck. She let out an excited gasp and squirmed more fervently under his touch.

"Please, don't... I'm not..." she whimpered quietly.

"Just admit it, you nasty little slut."

She shook her head from side to side in a futile effort to deny Lucas' accusation.

He put a disappointed expression on his face and moved to set her down on the ground. "Well, if you can't be honest abou—"

"No! Please, don't..." Eldwyn exclaimed, loudly enough to startle Kythril. Her arms clasped tightly around Lucas' neck, refusing to let go.

Lucas waited patiently.

"F-fine," she whispered. "It turns me on, all right? I... I want to watch you h-hurt my... my sister."

"I'm going to do more than that, pet. Much more," Lucas replied, grinning predatorily. "And as for you, are you going to be a good pet and obey me? Or maybe you both need a spanking today?"

"N-no, sir. I'll be good, I... I promise, sir," Eldwyn moaned, closing her eyes and tilting her head back, silently begging for another kiss.

Lucas obliged, pressing his lips against hers once again. She immediately parted her mouth for him and licked hungrily at his tongue, before deepening the kiss and letting her tongue dart into his mouth.

This time, it was she who broke the kiss first, breathing hard. "Now her, sir?"

"Not quite yet," he replied. "First you're going to strip naked. Consider it your punishment for being such a bad sister."

Eldwyn nodded eagerly as she began to unbutton her vest, still in Lucas' arms, and dropped it carelessly on the ground. Her hands trembled with excitement as she worked on the smaller buttons of her blouse, but soon it joined her vest, exposing her pale, skinny chest. Lucas set her down to allow her to remove her shorts, taking the opportunity to kick both pieces of clothing out of the way. When he turned back, she was naked, save for a pair of cute little black socks.

Kythril hadn't moved a muscle since Lucas had kissed Eldwyn, but now, from the edge of his vision, he noticed her casting furtive glances at her stark naked sister.

As much as he wanted to start working on the older sister, he wasn't quite finished with Eldwyn yet. Patience, he told himself. If he played his cards right, he'd have both sisters at his beck and call before the night was over. Don't blow it now, Lucas.

He glanced meaningfully at the ground in front of him, and after a brief moment, Eldwyn got the hint and sank to her knees. There was something wonderfully submissive about both the position as she stared up at him, waiting obediently for his next command. He reached down and stroked her cheek, and she nuzzled his hand like an affectionate kitten. She almost mewled.

Lucas reached for his belt and unbuckled it hastily, pulling it free. She licked her lips in anticipation, but as much as he'd enjoy a nice blowjob from his eager pet right now, he had another idea.

He circled her and knelt behind her.

"Hands," he said curtly.

Almost instinctively following his orders now, Eldwyn offered him her hands behind her back. With practiced movements, he secured her arms with the belt, pulling the improvised constraints tight.

Then he grabbed her by the scruff of the neck and pulled her back against him, drawing a little grunt of surprise, though she did not make any move to resist. Instead, she arched her back, leaning against him, her head thrown back on his shoulder. Even through his clothes he could feel the heat of her arousal on his skin. Between her legs, her erection bobbed up and down needily, a need which he planned not to address for quite a while.

"I'm going to go to your sister now," he whispered, "and you're going to stay right here, quietly, on your knees, like a good girl."

His order was punctuated by a gentle, chiding slap to her ass. The yelp that escaped from her lips was more due to surprise than pain.

"Yes, sir."

He gave a satisfied nod, got to his feet, and made his way over to Kythril, who met his eyes defiantly and though obviously nervous, stood her ground. He came to a halt right in front of her, clasping his hands behind his back and eyed her sternly.

"What do you want?" He asked.

Her surly stare remained fixed on him, but she said nothing.

"Do you want to leave?"

Silence.

"The rules are the same as before," he continued unperturbed. "If you want to go now, I won't stop you, but if you stay, you're mine until I decide to let you go."
