A Skilled Pussy Trainer's Demonstration - Fellatio Edition
Oppa lay comfortably on the bed, eyes closed in pleasure with his cock standing tall toward the sky. Roberta and Hyeonju then lay face down on either side of it, chatting.
"Watch closely. You need to memorize it so you can recreate it perfectly even when I'm not around. Pay attention to every single detail of what I do. Got it?"
"Yes! Of course!"
Roberta replied briskly, her eyes sparkling with excitement. There was nothing better than getting to watch a senior's demonstration up close like this.
Hyeonju began her advice as a senior, gazing at Roberta, who was staring at the cock with eyes shining almost too intensely.
"First off, one thing you gotta know for sure: biting down hard and sucking isn't the way to go. A cock has its own rhythm. You need to control the intensity, and the spots to stimulate change depending on the moment. It's fundamentally different from our pussies that get soaking wet and drip just from Oppa touching them. If you don't get this, you can't give proper service. Got it?"
"Yes! I've got it memorized."
Roberta nodded solemnly. She'd had no idea it was so profound and had just been thinking of shoving it in recklessly. She wanted to scold her past self.
"Explaining the details in words is tough... So I'll service Oppa's cock directly, and you watch closely then try it yourself. Got it? Watch good."
Hyeonju's lips touched Oppa's glans with a cute smack♡. It wasn't so much drawing out pleasure as signaling to Oppa that service was beginning—a little ritual of hers. But even that ritualized gesture was enough to flip the cock's switch once it became routine. The already impressive shaft swelled like it was about to burst, veins throbbing.
Hyeonju extended her thick, saliva-filled tongue languidly. She licked slowly, softly, meticulously from the balls up the shaft to the glans, planting another kiss at the tip. She sucked the precum right out with a smack, then enveloped the entire cock in her mouth, inserting it into her mouth-pussy. A lewd sluuuurp played like BGM in the ears.
"Whoaaa..."
Roberta moaned, entranced by the obscene sight. She didn't know the details, but it felt totally different from what she'd done earlier. Thinking deeply about Oppa's pleasure spots, not too aggressive but not boring either. Her sultry lips and tongue stimulating it fully—it was the ideal cocksucking personified.
And what surprised Roberta even more was that Hyeonju showed no sign of losing her mind while sucking that delicious cock. 'Amazing... She can stay so calm while sucking that tasty cock... If it were me, I'd be glued to it like an idiot, mouth-pussying away again.'
Roberta hadn't even touched it with her mouth yet, but the scent alone had her pussy in heat, juices flowing. If just the smell did this to her, what must Hyeonju feel actually servicing with her mouth-pussy? That self-control was incredible.
Sluuuurp! Slurp! Shluuurb! Chuuuurp, huuung...♥ Jup, chuup!
"Ooooh... Feels good. As expected from my little sis."
Like a gentle wave building strength, Oppa let out a satisfied groan as Hyeonju ramped up her mouth-pussy service. Her delicate fingers poked at his balls to heighten the sensation, her tireless mouth-pussy coquettishly pleasing him. Roberta burned every detail into her eyes, but deep down, she doubted if she could ever match it. It felt like she'd just taken her first step, only to face a max-level pro right in front of her.
As Oppa received his little sister's mouth-pussy service, it seemed time for him to cum. Without a word, he unleashed his load, and Hyeonju pursed her lips expertly, skillfully catching the flood from the glans. After about a minute of ejaculation, Oppa slowly sat up.
Hyeonju opened her mouth wide to show him the semen she'd received.
"Okay, checked. You can swallow."
"Mm..."
Only after his permission did Hyeonju gulp down the sticky, gooey semen with a sweet haa♡. There was an intense eroticism in her demeanor. Swallowing semen alone turned a woman into a full bitch. Seeing the clear ecstasy in Hyeonju's eyes, Roberta swallowed dryly and asked,
"H-how is it? Is semen that delicious?"
"...Huh?"
Hyeonju looked down at her like what kinda obvious question is that?, then realized Roberta hadn't tasted it yet. The cleanup fellatio earlier had just been cleaning up remnants—no blessing of receiving a full load.
Some things were better experienced than told. But Roberta was still too inexperienced to properly milk Oppa's semen. No choice—Hyeonju would have to teach her.
"Of course it's the absolute best taste, no question. Semen is basically all the delicious parts of a cock condensed. Just sucking cock without receiving semen is like building a high-end PC and only playing pinball—total waste."
"I-it's like that?!"
Roberta's eyes went wide at Hyeonju's testimony. Just sucking cock felt that blissful—how much better must receiving semen be? She couldn't even imagine.
"Anyway... You saw how I did it, right? Might be tough for beginners, but for Cock-sama's pleasure, this is basic stuff you gotta do."
"Mm... I-I'll do my best. But honestly, I don't know if I can pull it off properly."
"Don't worry, a pretty pussy-bitch like you just showing effort gets him hard anyway. If it's no good, I'll adjust it myself."
Oppa encouraged the uncertain Roberta. How could someone be so kind? Grateful for his consideration, Roberta steeled her resolve to become a better pussy-bitch.
"When mouth-pussying, the most important thing—sure, technique and timing matter, but above all, it's the mindset of thinking about the cock. Got it? If you truly care about the cock and want to make it feel good, your senses open up to its movements and reactions. Follow that, and your service naturally perfects. That's what you need to become. Got it?"
Hyeonju instilled her cock-service philosophy into Roberta. To Oppa, it sounded like ridiculous nonsense, but to Roberta, it rang like words from a sage. Her eager, wide-eyed reliance was perfect motivation for the teacher.
"And one more thing to nail down: when mouth-pussying and the cock cums, unless the guy says otherwise, the basic etiquette is to catch it all in your mouth. Show it to him properly for inspection, then swallow after approval. I see pussy-bitches skipping this a lot. Oppa's generous and lets it slide, but don't you do that. You're here to learn proper etiquette, right?"
"Yes! I'll memorize it."
Roberta neatly organized these new etiquettes in her mind. Each one made perfect sense on reflection. Wasting a load he'd graciously given by spilling it was disrespectful. And since semen came from the man, it was obvious you'd need his permission to swallow. It seemed so natural, yet hard to practice without guidance. That's why you needed a teacher.
"Mm... Seeing you properly mentor like this makes even me as her bro feel proud. Since we're at it, why not demo proper pussy-work too, not just fellatio?"
"Yeah? Well, a good example would help Roberta anyway. Got it."
Hyeonju used Roberta as an excuse, but her upturned lips betrayed she just wanted Oppa's cock. Roberta memorized that too. That's the proper pussy-bitch attitude. Remember.
Hyeonju placed her hands on Oppa's chest, lifting her hips to align her pussy with his cock tip. Dripping honey from her pussy wet the shaft before full insertion.
"Watch closely now? Earlier was doggy, so Oppa just had to thrust. But cowgirl means the pussy side does the service. Technique and knack matter here too, so burn it into your eyes for later. Got it?"
"Y-yes!"
Roberta's eyes widened, determined not to miss a second of their coupling. And as if showing off to her, the siblings' mating began.
