She stays

Kythril hesitated, then slowly and reluctantly moved towards Lucas, slowly laying over his lap. She adjusted herself several times, trying to find the least humiliating position and seeming unable to find it.

Lucas savored the moment. He slowly ran his fingers along the small of her back, marveling at how magnificent her ass was even through the fabric of her modest dress. Her cheeks were full and round, and he couldn't wait to see them turn a burning red under his palms. She shuddered under his touch, but otherwise kept still.

He took a deep breath. Start slow, don't scare her off.

He brought his palm down onto her ass. It was a fairly gentle slap, but she yelped anyway. He suspected it was borne more from surprise than genuine pain.

He kept his hand on the spot he had just hit, waiting for her to unclench, then he brought his hand down once more, a little harder this time.

"Ah!" she cried out.

He gently rubbed the spot he had hit, as though to soothe the pain away, then brought his hand down on her other ass cheek. This time she was more prepared and only reacted with a low moan, her body stiffening on his lap.

He continued to spank her in this manner, harder and faster, but it didn't have nearly the effect he wanted. The impacts were being dampened a lot by the thick fabric, and now that she'd gotten over the shock of being spanked—almost certainly for the first time in her life—she barely reacted any more.

Eldwyn's eyes had been glued to the spectacle in front of her and she reached the same conclusion. "This isn't working. Lift her dress," she said, the statement equal parts command and plea.

Kythril tensed up, but the objection he expected didn't materialize. Lucas figured that was all the consent he needed. He took hold of the long skirt and drew it up her legs. First her calves came into view, then the backs of knees, then her thighs. He could feel her breathing accelerate, her chest moving against his leg. She made no effort to assist him, but to his surprise, she didn't struggle either as she was slowly being exposed by a stranger.

Finally, he looked upon her ass. Lucas swallowed. It was gorgeous, he admitted—but not out loud. They were full, round, and firm, framed by a simple pair of sensible cotton panties that were only slightly lighter than the milky white cheeks that had evidently never seen the sun. White, except for the two lightly pinked spots where his blows had landed.

He placed his hand upon one of them, feeling the heat radiating from it. Again, she tensed at the unfamiliar touch from a strange man, but she continued to remain dead quiet.

He was about to change that. He gave her one last caress, then brought his hand down in a proper slap. The impact of skin on skin created an audible impact that resounded through the room. Kythril howled and reared up, but Lucas had anticipated that and had a firm grip on her with his other hand.

"Again!" said Eldwyn, her eyes wild.

Lucas was happy to comply. Not giving Kythril a chance to recuperate, he smacked the other cheek just as hard. She cried out again, lifting a hand from the floor to protect her ass. A brief struggle ensued, but Lucas had the advantage in strength, plus a far better angle than her. It took only moments for him to incorporate her wrist in his grip on her back.

Her only avenue for escape now firmly closed off to her, she tried another approach. She glanced pleadingly over her shoulder. "Please! Please, stop! It's... It's too much, I'm sorry!"

He had been torn before, and he plea briefly froze his arm, already lifted into the air to deliver the next spank. Unfortunately for her, her slowly coloring ass looked incredibly enticing and he wanted more. No amount of crying would stop him. Her hopes dashed by his dispassionate expression, Kythril's face fell and she sagged on his lap.

Lucas resumed his methodical torment of the thick ass on his lap, slapping first her left cheek, then her right, alternating over and over again. He stepped back from the amount of **** he used from the first two spanks on her bare ass, but only slightly. They were still severe enough to make her cry out with every impact, but not quite hard enough to make her give up.

"Ahh!" Another slap.

"Uhhh!" Another.

"Aiii!" Another, a little lower.

Every time he brought his hand down, her skin color got a tone deeper, first pink, then red. He paused between hits, noticing it took her longer and longer to recover from them. Her exclamations changed character too, turning from cries to wails to shrieks, but Eldwyn had no mercy.

"Keep going," she demanded. "She deserves it!"

He continued, determined to give her what she wanted—or needed. The smacks landed on her ass with a thudding sound, and tears were running down Kythril's face. Her voice changed again, becoming quieter but somehow more ****, as if worried her torment would never stop.

"Uhhhnn..." Another slap.

"Mnnnggh..." And another.

"Ugghhh..." On the other cheek.

"Mppphhh..." And again.

As time went on, Lucas could tell she was starting to buckle under the pressure.

He eyed Eldwyn questioningly, but she didn't even seem to notice him, her awed gaze fixed on the deep red of her sister's ass. Kythril had been reduced to weeping softly on his lap. He could feel her body quaking in agony as she waited helplessly for the next blow to fall.
