Chapter 10: R-18 Yara's Teachings / Last Part.
Yara was completely dumbfounded as she looked at the scene in front of her: in Lyon's groin area, his pants had a huge bulge.
"Lyon, are you erect?" Yara asked him.
"I don't know, but my 'little brother' is like this because he thinks about you and how beautiful and attractive you are..." Lyon replies as he blushes with embarrassment.
Hearing Lyon's words, she is even more astonished, but at the same time very happy that her brother is feeling turned on by her.
"Lyon... Do you really think I'm pretty? After all, boys usually like girls with small breasts and buttocks, but look at mine they're huge!" Yara tells him, and at the end of her sentence she sighs sadly as she talks about herself.
"I like them big! You're very beautiful, Yara!" Lyon tells her, and it makes her smile a little to know that her brother was honest in his words.
"Uh... Thank you, Lyon!"
"Would you like your sister to teach you how to masturbate? It'll be my first time with a boy, but I'll try to make sure you like it," Yara asked her.
"Yes! Please, sister... It hurts to be like this!" Lyon tells her.
Without wasting any more time, she runs her trembling hands down Lyon's pants towards the button and zipper; after a few attempts, she manages to get the zipper down and remove the button.
"Lyon, could you stand up so that I can lower your pants and your crotch is at my face level?" Yara asks.
"Yes!" After confirming, he stood up and looked intensely at his beautiful sister, who was now totally focused on his crotch.
After Lyon stands up, Yara takes both hands to the sides of his pants and begins to pull them down. After a few seconds, a huge dragon leaps out and hits Yara on the nose, right in front of Lyon's crotch.
Pow...
"Ouch... That hurts!" says Yara after being beaten by Lyon's penis, which makes him laugh a lot.
"Hahahahahahaahha... That was really cool!" Lyon comments.
"Humph!"
After Yara snorts and pouts, she refocuses on Lyon's huge penis, which is now facing her face.
"Wow, it's so big! In books they don't measure more than 3 inches, but yours must measure more than 8 inches!" Yara comments, and this makes Lyon feel proud of himself.
"Lyon, I'm going to pull down your underwear, okay?" Yara asks him.
Upon hearing Yara's question, Lyon's heart leapt up and started beating even faster in anticipation of what would happen.
"All right." Lyon says.
Yara took her hands to the sides of Lyon's underpants and slowly began to pull them down.
After a few seconds she completes her goal of lowering Lyon's underwear, and looking at the huge penis in front of her, she slowly begins to succumb to desire.
She approaches Lyon's penis and begins to smell it thoroughly.
Sniff... Sniff... Sniff...
Lyon was totally dumbfounded by the expressions her sister was making as she sniffed his penis.
"Do you like the smell of my penis Yara?" Lyon asked her.
On hearing Lyon's question, she came to her senses and moved away a little.
"I'm sorry, I..." But before she could continue, she was interrupted by Lyon.
"It's okay, I like watching you do it, you can continue." Luyon tells her.
"O-ok Lyon."
She moves closer again and starts intensely sniffing Lyon's entire penis, she first goes towards his balls and starts sniffing them while making dirty comments.
"Sniff... Sniff... You smell so stimulating, Lyon!"
"Aaaah... Sniff..."
Then she started sniffing his shaft and moving towards the head of his penis, which was covered by his foreskin. When she finally reached the tip, she put the tip as close to her nose as possible, even touching it, and started sniffing it intensely.
"Sniff... Sniff... aaaah... That's the best smell I've ever had, so that's what a man's penis smells like." Yara comments.
Without wasting any more time, she tells Lyon that she's going to start masturbating him.
"Lyon, I'll start. According to what I've read in books, you should hold the shaft of the penis and move it up and down to stimulate a man, let me know if it hurts." Yara tells him, and Lyon just nods in confirmation.
She takes one of her hands to Lyon's shaft and starts to pull the foreskin down, but is interrupted by Lyon just as she starts.
"Wait, that hurts! It's like the skin is stuck..." Lyon tells her.
"I see... Then I'll do it differently, I'll use my tongue to push the skin down slowly." Yara comments and then begins.
Yara sticks out her little pink tongue and begins to gently lick the small part of Lyon's glans that was exposed. After a few seconds of licking, she notices that the foreskin is a little looser and decides to continue pulling it down, this time instead of using her hand, she pushes it with the tip of her tongue.
Soon the foreskin was completely down, leaving only Lyon's pink glans exposed to Yara's view.
Having succeeded, she decided to ask if he was still in pain, but seeing Lyon's face left her completely enthralled.
Lyon had both hands covering his mouth to stop him moaning while his whole face and ears were red from embarrassment, and when he saw that Yara was looking at his face, he looked away.
"Lyon, did you like it when my tongue was touching your penis?" Yara asked him.
"Yes! I loved the feeling..." Lyon replies in a shaky voice.
"Fufufu... I see, in that case I'll make you feel even better!" Yara comments.
After saying this, she brings her mouth close to the head of Lyon's penis and, opening wide, she takes the head of Lyon's penis inside her.
Suddenly feeling the strong stimulation, Lyon can't help himself and lets out a moan.
"Hnnnnnnnng!"
Hearing her brother's soft moan, she begins to move her head and suck on the head of his penis while using her tongue to savor the sweet taste of her brother.
"Glub...Glub... L-Lyon do you like it?" Yara asked him amid the lustful sounds coming from his mouth.
"Y-Yes!" Lyon replied.
Yara was really enjoying making her brother feel good, so she increased the pace to make him have his first orgasm.
After a few minutes of fellatio, Lyon was finally on the edge and felt something coming from his penis.
"Yara, something's coming!" Lyon says.
But this only made her increase her pace even more, and after a few seconds a huge load of semen gushed into her mouth.
Lyon, feeling the intense pleasure he's never felt before, can't help but moan.
"HNNNNNNNNNNG! THIS IS GREAT!!!! HNNNNNNG"
After a few seconds, his penis finally stops pumping semen into Yara's mouth.
Yara's current state was a bit funny, but very sexy...
She couldn't contain all her load and there was semen dripping out of her mouth and nose, but she was still frantically trying to swallow it as if she were tasting the best candy in the world.
Yara removes the penis from her mouth and brings both hands to her face to collect every drop of her dear brother's semen, after a few seconds she finally collects it all and decides to show her brother how she would taste his sweet semen.
"Look Lyon, it's called semen, it's something that men eject when they have an orgasm." says Yara.
After saying this, she takes the semen from her hand to her mouth and swallows it.
"Lyon, that's all for today, get dressed, it's time for lunch," Yara says to Lyon as she looks away to hide her embarrassment.
Lyon just nods and starts to get dressed again, but even though he had just had an orgasm he was still hard as a rock, but Yara was right, it's time for lunch and their mother will be calling for them.
With no other option, he simply puts his erect penis back into his clothes and decides to go back to his room.

Jhon_Sinners I didn't know how to describe the fellatio sounds of a penis inside a mouth so I described it as 'Glub' if anyone knows how to write it differently let me know.
