She was very upset.
Not only was she unable to drink his cum to improve her vocals, what had her most upset was she failed to deliver; she failed to do what was expected of her. Kind Joon Oppa was trying to train and help her, and she did not do her best to improve. She could not make him cum and bring him pleasure. Joon had helped her so much and she could not satisfy him and make him a happy fan. She has failed as an Idol and as a trainee.
She felt as if she just messed up a performance and was booed off a stage. It was a most terrible feeling for her. She felt even worse than when her vocal coach was upset with her singing.

Joon of course, could almost read her mind, her innocent and predictable thinking was easy to understand. Her innocence and desire to please and improve is actually pushing her, making it easier for her to become their slut. She now wants to please him, she now wants to drink cum just for his satisfaction. To make him happy.
And this pleased him to no end.
And now, this part of his plan has succeeded. It is time to proceed to the next part.

"Don't be upset, you worked hard, I can see it. Don't cry now. I can't bear to see you cry."
"Sorry Oppa.. " She sniffed as she fought back her tears.
Seeing she really was about to cry, he said, "Tell you what, I will let it go today as well, Okay? Forget about the time. You can continue to do fellatio until I cum and you can drink it. Just consider it as you owe me another favour, okay?"
"Really Oppa?" Her eyes now were shining with hope and joy through the tears.
"You better get started before I change my mind." He teased.
"Thank you Oppa!" she almost shouted her thanks as she quickly wiped her tears off with the back of her hand.

Right away, Seohyun put her hands and mouth to work, stroking his cock earnestly and eagerly licking the tip with her tongue. It has only been less than a minute since she stopped her blow-job, so his 'monster' is still very erect and hard. And still wet and covered with her saliva.
Within minutes, she was sucking his cock hard and putting it deep inside her mouth.
Joon did not endure or control his feelings this time, he just went with the flow and enjoyed the awesomeness of having a SNSD member suck his cock.
She took his cock as deep as she could, hoping to suppress her gag-reflex more, and let her mouth and upper throat get used to his size and thickness. She would then slid his 'Monster' in and out, feeling her tongue and mouth rubbing against his shaft and swollen glans. His bulging veins were even more prominent than his brother, and Seohyun could feel them brushing against her lips as she brought the scalding hot meat-rod in and out of her mouth.
Each time she pushed it deep, she could feel the big glans slid past her uvula, then press onto her tonsils and then deep into the back of her mouth, before ramming into her upper throat. She could then feel her muscles gripping it tightly as her throat narrowed from the distended muscles. And when it pulled out, her muscles would feel the stretch and tightness and then relief from the release in pressure.
Before long, his 'monster' could go in almost 5 inches without her gagging. It felt absolutely fantastic for Joon.
Seohyun then did the same thing she did yesterday with Jongin; she sucked and squeezed his cock hard, then while doing this, she let it slid out a bit, then she breathed quick and then slammed her mouth and upper throat on his 'monster' tip. Just like with Jongin, this gave Joon little time to rest from the glorious sensations of her squeezing, and she repeatedly did this, pushing him closer and closer to the edge. She now also combined this with her tickling tongue, curling it to press on his frenulum as his cock slid in and out of her mouth.

Soon, less than 10 minutes later, he was all swollen and hard and ready to blow.
"Get..... ready, Seohyun-ah." He mumbled, barely heard through the loud, wet and slick sounds filling the studio.
"Uhhh!! Get ready to receive my hot cum. Lean back and open your mouth wide!" He spoke between grunts of pleasure. His right hand grabbed the base of his cock and he sat up straight.
Seohyun was bobbing her head up and down when she heard him, and immediately, let his cock out of her mouth and leaned backwards with her mouth wide open, as he took over his own cock. She sucked in air quickly, in anticipation of her new favourite morning drink .
"Uhhh!!............... AHHH!!!" Barely 3 seconds later, he shouted out and stroked his cock furiously before a massive spurt of his milky cum shot out in a huge burst of whitish fluid. She reflexively blinked her eyes as a long ropey trail landed right on her face, but she quickly adjusted her position in time to capture the remaining bursts of his precious cum in her wide mouth.
Joon was able to help by directing his cock, aiming into her open mouth and shooting several more thick shots of his cum onto her tongue. "Remember, don't swallow it first!" He was quick to remind her, still able to think clearly despite having his orgasmic cock shooting cum into her mouth at that very moment.

Hot cum entered her mouth and a thick, heavy smell entered her nose. Despite this being only her fourth time tasting cum, she is already beginning to get familiar and used to its small and taste. All this delighted her, as she is slowly coming to associate his cum as something helpful and good for her throat and vocals.
Soon, he is spent and he sat back, gasping and catching his breath, while she is panting also from her efforts at sucking him off non-stop for 10 minutes. But she somehow remembered to keep her mouth open and did not swallow. Her open mouth is now filled with cum, and she tried to catch small drops of cum with her fingers as they drip off her face.
"Don't move, and lean backwards. That will stop the cum from dripping off. Let me handle this." He advised her.
And she obeyed, leaning backwards to stop the cum dripping. Joon used his finger to wipe off the cum droplets off her face and cheeks and deposit them on her outstretched tongue. It took him another minute before almost all the cum on her face was collected into her mouth.
"Good girl. Now slowly swirl and coat your mouth and tongue, and then let it flow down slowly to coat your throat as well. You got more vocal lessons today, so don't miss the opportunity to lubricate your throat."
Again, she was very obedient and did exactly what he said, slowly swirling the cum inside her mouth, making sure it coated her tongue and teeth even, before she leaned back to let the sticky jizz flow backwards down into her throat. Until it passed a point and she swallowed slowly. Joon could see her throat muscles gulping to push the cum down her oesophagus.
It was sexy and slutty beyond his imagination.
"My personal cum-deposit slut Idol!"
