Chapter 50 — A Big Sis With Foot Fetish.

"Yes, we can do that," Ruby said, probing for clarity, "but did you have any special reason for asking, Kael?"

"Of course I did," Kael replied. He paused before continuing, "Half the time I’ve been in this bathroom, you’ve been staring at my feet."

Ruby felt her cover being blown. Her face burned with shame.

"And now that I think back on it, you’ve always seemed very interested in my feet," Kael mused, acting as though he were tallying the many times Ruby had used them to satisfy her desires.

Ruby stared at the floor, her face a deep crimson.

Kael might have been unaware of exactly what was happening between him and his sister back then, Kael thought to himself, but after being exposed to a whole different world, the gap between our knowledge is simply incomparable.

"I’m sorry, Kael," she whispered.

More than the fear of her secrets being exposed to the world, Ruby felt a profound disappointment in herself.

How could I have done those things to Kael? As the thought crossed her mind, tears began to stream down her cheeks.

She was on the verge of breaking down entirely when she felt hands firmly gripping her shoulders.

"Oi, Sis, why are you crying? Did I say something mean?"

Ruby looked up to see Kael standing before her, his expression filled with genuine concern.

She had braced herself for him to blame her for the "bad things" she had done to him when they were children, but his reaction left her bewildered. He wasn’t angry; he was simply worried about her tears.

"Kael... you... you don’t hate me?" she asked, her voice trembling.

"Hah? And why would I do that?" Kael acted as though he were genuinely confused by the question.

Ruby decided to probe a little further. "But... what about the things I used to do in the bath?" she asked, her voice still trembling with residual sobs.

"What things?" He tilted his head, feigning ignorance before his expression shifted, as if he finally comprehended the situation.

"Oh, you’re talking about you licking my feet? Why would I hate you for that? I didn’t feel uncomfortable at all while you did it. In fact..."

Kael continued, lowering his voice to a shy, bashful tone, "...I actually liked the ticklish feeling."

It was the perfect scenario for Kael to construct; he knew this was his best chance to absolve Ruby of her guilt.

To say Ruby was delighted would be a gross understatement. Kael’s explanation dissolved the vast majority of the heavy burden she had been carrying, but she needed to be certain.

"But Kael," she whispered, her voice barely audible, "don’t you feel... I mean... disgusted by your own older sister?"

Kael heard her clearly. He softened his expression and replied, "Why would I feel like that? If you enjoyed what you were doing, why should I be disgusted? Besides, everyone has a secret or two that they don’t tell anyone. Honestly, I should be thankful to you for sharing yours with me."

He offered her a warm, innocent smile that seemed to wash away the last of her shadows.

Ruby was entirely unprepared for this turn of events. It was a complete departure from the nightmarish scenarios she had imagined if her secret were ever exposed.

She couldn’t handle this sudden, overwhelming surge of sweetness from her little brother, and combined with her pregnancy, it left her feeling physically weak. Her knees gave out, and she sank onto the floor.

"Kael, you can leave if you want," she murmured, clutching her stomach. "I just need to rest here for a bit."

Kael sat down beside her, offering a gentle comfort. "Haha, Sis, you’re such a crybaby, even with a little one on the way," he teased, trying to lighten the mood.

"Thank you, Kael. Your words have really helped ease the massive guilt I’ve been carrying," Ruby admitted. She took a breath, resolve hardening in her voice. "I’ll try to control my desires from now on."

"But why would you do that?" Kael asked, acting genuinely befuddled. "Don’t you love doing it?"

Ruby sat in silence for a few long minutes, processing his question, before she finally nodded. "Yes, I love it. But it isn’t something this world would ever accept. People would find my behavior repulsive."

Kael leaned in, his expression shifting to one of conspiratorial warmth.

"I understand that. But don’t you have me? You can always do it with me, and we can just keep it our little secret." He let out a soft, playful giggle, acting as if the suggestion were perfectly natural.

Ruby was overwhelmed with happiness, touched that her brother cared so much for her that he would not only keep her secret but offer his assistance to help her manage her suppressed desires.

"No, Kael, I can’t do that to you," she murmured, struggling against her own heart. "I’ve only just managed to climb out of that quagmire of bad choices; I can’t let myself fall into those patterns all over again."

Kael saw that her guilt was still anchored deep, and he knew she needed a firm push to finally let go.

Moving with newfound authority, he sat on the bathroom stool and firmly placed his bare foot directly against her chest, right between her breasts.

"Come on, Sis. Get started," he commanded softly. "My feet require some cleaning."

Ruby sat on the floor, still sulking and conflicted, staring at the foot resting against her. She knew he was trying to help her, and her instincts urged her to resist, but the sight of his small toes wiggling against her skin caused her resolve to crumble.

Her mouth watered at the sight. Unable to hold back any longer, she reached up, grabbed his foot, and pulled his big toe into her mouth, looking up at Kael with a sudden, seductive intensity.

Kael felt the warmth of Ruby’s tongue against his toe and offered her a supportive smile.

Seeing that expression, a surge of confidence replaced her lingering hesitation. Casting aside her remaining shyness, she began to engage with his feet with newfound purpose.

She reached out, took hold of his other foot, and pressed it firmly against her breast, cradling it there while continuing to focus her attention on the first.

She used her tongue to explore the spaces between his toes, occasionally pausing to suck gently on them.

After a while, she shifted her position, holding his foot steady in front of her face, and began to trace the length of his sole with slow, rhythmic licks.

Kael had initially believed he wouldn’t find this physically pleasurable, thinking it would be purely a matter of mental satisfaction and the dominance he felt watching Ruby worship his feet.

However, as she began tracing the arch of his sole, a pleasant, electric tingle shot up his leg, intensifying into a deep, ticklish sensation that took him by surprise.

Her soft tongue traced every contour of his skin with intoxicating precision.

Wanting to heighten the sensation, Kael began to stroke himself slowly. With his free foot, he reached out, using his toes to gently tug and tease at Ruby’s nipple.

The combination of his touch and her focused attention proved highly effective; a soft, broken moan escaped Ruby’s lips, her rhythm quickening in response to his newfound boldness.
