"Good Boy..."

Yawning, you walked through the dark hallway sleepily. You had spent the night in exo's dorm, due to your own family issues. You were very close with all of them, so they had no problem letting you stay.
It was about 2 in the morning, and you had woken up to go to the bathroom, but as you approached the bathroom door, you heard some peculiar noises coming from the other side. You pressed your head against the wood and listened carefully. A deep moan was heard followed by "Ah, y/n. Yeah, just like that baby." A loud gasp escaped your lips as you jumped away from the door. You could tell who it was just by a couple of words, it was Chanyeol. 'What? Why is he MOANING my name?' Curiosity took over you, as you leant your head back towards the door. A sudden urge took over your body, you felt arousal grow inside of you as you heard his inconsistent moans. Something took over your body, you reached your hand out and grasped the door handle. Opening it slightly at first, but then you pushed it open all the way to see a naked Chanyeol, sat on the toilet seat, stroking his member. His eyes opened wide in shock as he tried desperately to cover himself up. The colour red covered his face as he grabbed a towel off of the rack and stood up.
You held a finger to your lips and approached him slowly. A calm expression caked your face, as you caressed his neck with your hand. "Have you been a naughty boy? Have you been calling noona's name as you pleasure yourself?" You cooed sensually.
"N..nnnoo. Noona." He managed to stutter.
You spanked his bare backside before speaking the words "Lying will get you into even more trouble." His face sensed pain, as his backside became red from the impact of your cold hand.
"Now. Answer Noona. Were you, or were you not, just moaning my name?" You asked whilst your hands explored his bare torso. Your hands ran all the way down his back and around to his chiseled abs. He moaned slightly just from your touch.
"Y... Yes Noona." He said as he looked down at the ground, feeling ashamed.
"That's a good boy." You breathed the words out onto his bare neck, reached your hands down, and pulled away his towel, letting it drop to the ground. You felt his member pulsing, against your jeans, he was desperate for your touch.
You slinked your fingers down his abs and circled his v line. His breath became uneven as you got closer and closer until suddenly, he took a deep, jaggered breath in as you lightly swept your hand over his pulsating member. You started off slow, barely even touching it, teasing him which drove him mad.
He let out loud torturous moans, which filled the room with sensuality.
You grabbed his member hard and began to stroke it fast, earning exasperated moans of pleasure from Chanyeol.
"Ah, noonaaaa." He breathed the words in between harsh exhales.
You planted kisses on his neck, and slowly worked your way down his body, leaving hot saliva trials.
Puckering your lips, making yourself look as sexy as possible, you kissed the head of his member which caused his body to shake.
Taking him all in your mouth, his body jolted forward into your mouth, instinctively. Pulling back you spanked him hard on the ass, leaving a mark "Naughty boy... Don't you want noona to do this? Should I go back to bed?"
"Anniya! I'm sorry. I'll be good, just please, noona, I need you."
You gave him a satisfied smirk as you leant back down and starting sucking. His pre cum leaked out and you moved it all around with your hand, as your mouth worked at the head. By this point he was a moaning mess, and was struggling to keep still. You sucked harder and harder as your hand stroked faster and faster on his long length.
"Nnn. Noona. I. I'm gonna cum..." And with these words his sweet juices squirted into your mouth. You swallowed it all up, and rose from your knees. You kissed him gently on the lips and walked out, you uttered the words "Good Boy" before walking past the door and down the dark hallway.
