Chapter 66: — The First Sex.

Kael took hold of his cock and stroked it a few times. Ruby looked doubtful when she got a clear look at his size.

She had known for a long time that Kael had an abnormally large penis, but she was his older sister, and she couldn’t let him develop a complex about it. She smiled and let him explore her.

Kael began to do exactly that. He rubbed her labia together, pinched them lightly, and slid a finger inside her wet, pulsing slit.

Ruby laughed as she watched Kael; he looked like a child who had just received an expensive toy and was terrified he might break it if he wasn’t careful.

“Why are you laughing, sis?” Kael asked, his face full of genuine confusion.

“Ahem… brother, I’m just laughing because I remembered something funny, so you can continue,” she said, quickly salvaging the situation.

Kael kept playing the part, acting naive as he explored her body. He couldn’t just dive in and start using his dick with expert precision; he had to make it look like this was the first time he had ever seen a woman’s cunt up this close.

While teasing her opening, he suddenly pinched her clitoris.

“Ahhh! Ahhh… mmmm!” Ruby cried out.

Her clitoris was incredibly sensitive due to the pregnancy, making her whole body jolt.

“Kael, you really need to be careful with that part,” she panted, looking at him with flushed, glossy eyes. “I’m sorry, but right now I am just extra sensitive there.”

“Okay, sis,” Kael replied. Even though he said it, he didn’t let go. He kept his fingers firm on her bud, showing no intention of releasing it.

Ruby could only offer a wry, knowing smile at her brother’s persistence.

Kael continued his charade, putting on an elaborate performance of a naive, fumbling youth encountering a woman’s body for the first time.

He moved his hands with deliberate hesitation, masking his true experience behind an act of clumsy curiosity.

However, there was one person in the room who saw right through his facade. From her own intimate experiences, Mira knew for a fact that this was not Kael’s first time exploring a vagina.

She vividly remembered how he had tasted and licked her until the sensations were so overwhelming that she had lost control and wet his face. The memory still made her blood boil with a mix of lingering frustration and resentment.

Furthermore, Mira was well aware of his secret history with their mother. She had seen him with her own eyes—licking their mother’s pussy with a level of skill that completely betrayed the innocence he was currently feigning.

At first, she had been baffled as to why Kael would bother putting on such a show in front of Ruby.

She watched him carefully, observing the way his fingers actually moved versus the awkward expressions he made. Then, it clicked. She deduced the reason all on her own.

Mira reached a conclusion: Kael was just being a sweet, kind brother, wanting to make Ruby feel special by pretending she was his first. If Kael ever heard her thought process, he would have laughed his head off.

The truth was far simpler and messier: Kael had just completely forgotten that Mira was in the room and that she knew exactly what he was capable of. He wasn’t really acting to protect Ruby’s feelings; he had just had a lapse in judgment.

He probably wouldn’t have worried about it even if he realized it. Mira, however, felt a strange, happy flutter in her chest.

She took pride in the fact that Kael had tasted her cunt long before he had ever touched her older sister. “Hehe,” she giggled to herself, a sound so quiet that it went unnoticed.

Kael and Ruby were far too busy—he was deep into his act of playing with her slit and pussy, and she was too lost in the sensation—to pay any attention to the younger girl watching them from the corner.

“Kael, you don’t need to be afraid. Just put your penis against my lips and slowly push it in,” Ruby whispered, her voice encouraging and gentle.

Kael found it incredibly cute that she was trying to teach him how to have sex.

He suppressed a dark laugh, thinking, She would probably faint if she knew how I really fuck.

He remembered how their mother, Amelia, had complained that her ass was sore for a whole week after he had finished with her.

“I have a better idea, sis,” Kael said. He climbed onto the bed and stood directly in front of her, positioning his stiff, throbbing cock right at her face.

He idly wished he could capture the moment, but he pushed the thought aside. “I’ll put it in your mouth first. Once it’s good and wet, I’ll slide it into your pussy.”

Ruby smiled, looking up at him with adoration. She thought his suggestion was brilliant, never suspecting the darker, more experienced intent behind his words.

Ruby had never needed to lubricate anyone before; usually, she was wet enough on her own, or her husband didn’t require such measures.

But Kael was different. With him, she felt an intense, almost needy anticipation that made her glad for his suggestion.

Her thoughts were interrupted when Kael pried her jaws open and thrust his cock inside.

With Ruby’s head pressed firmly against the wall, Kael didn’t need to hold her still. He gripped her head and began to piston, driving his length in and out of her throat.

Even with his best effort, he could only get about half of his thick shaft inside her mouth.

As he worked, his mind drifted.

I knew Aunt Suna was a special case, he thought.

He couldn’t help but compare the two women. His aunt possessed a natural, innate talent for deepthroating, taking his entire length with a practiced ease that made every session feel like a masterclass.

Ruby, while eager and willing, was a different experience—less skilled, but far more precious to him in the moment. He continued to fuck her mouth, enjoying the tight, warm suction of her lips as she struggled to keep up with his rhythm.
