Upon hearing Lyon's comment about the smell on his hands and his curiosity about what masturbation was, Yara froze completely.
"haha... What are you talking about? I don't know anything about it..." Yara says, trying to cover it up.
"Sniff... Sniff... You promised to be nice to me, but now you're trying to hide it from me?" Lyon pretends to be starting to cry and brings both hands up to cover his eyes.
Seeing the look of Lyon about to cry, she despairs and tries to calm him down.
"It's all right! I'll tell you... Just don't cry," says Yara.
Hearing the answer he wanted from his sister, he immediately drops all pretense and looks at her with expectant eyes. Yara, realizing she's been tricked, is stunned.
"You're very naughty, Lyon!" Yara says.
"Hehehe... Sorry, I'm really curious..." Lyon replies.
"Aaahhh... Whatever..." Taking a deep breath to find the courage to tell him, she finally begins to explain as her face begins to heat up from the rather embarrassing subject.
"I was masturbating, women usually do it to satisfy themselves..."
"You boys don't usually do it because you don't feel as much sexual stimulation as we women do." Yara says.
"Hmm... Could you show me how you do it?" Lyon asks while wearing an innocent expression.
Yara feels her heart leap wildly as she hears Lyon's request. Feeling her heart beat faster and faster and feeling more and more elated, she decides to accept his request.
"All right... But you have to promise me that you won't tell anyone about this!" Yara says to Lyon.
"Uh-huh. Yes, I promise to keep it a secret." Lyon replies, as he becomes increasingly curious as to what his sister is going to do.
Yara then stands up on the bed and starts to breathe deeply, thinking about what she was about to do, so she decides to confirm it again with Lyon.
"Lyon, do you promise not to hate me for this in the future? If you find what I'm about to do disgusting, please tell me and I'll stop at any time." Yara asks.
"Don't worry Yara, I would never find you disgusting, I'm looking forward to finding out more about you!" Lyon replies.
Listening to Lyon's innocent encouragement, she took courage and began to pull down her jeans in front of her younger brother. After a few seconds, Lyon saw her beautiful legs and thighs exposed, and a little higher up he saw her pretty pink lace panties.
In her crotch area there was a large wet spot on her panties, which he decided to question her about.
"Sister, your panties are wet... Also, where's your little brother?" Lyon asks her as he feels embarrassed to ask such personal questions.
Listening to her brother's questioning, Yara realizes that he didn't know much about a woman's body, so she decides in her mind that she should be the first to show him all about it, which makes her delighted.
"Cough... Cough... You don't seem to know much about a woman's body so I'm going to teach you so that in the future no woman steals you from us!" Yara said confidently, but her confidence didn't last long as she soon began to think of the embarrassing things she would have to do and say to him.
"Wow! Thank you sister, I'm glad that my first time discovering something like this will be with my beautiful sister!" Lyon told her, and his comment seemed very effective as it helped her regain her confidence.
'Yes, who but your big sister could teach you something like that? Of course I won't let any unknown girl touch my dear brother!' Yara thought to herself.
