I hope you guys are ready for this (not really) XD
Jooheon's fingers and tongue continue their assault on your most sensitive areas, making breathy moans spill from your lips. Your chest rises and falls with each beautiful sound, and as your excitement builds, you dig your nails into his flesh and your thighs begin to twitch around him. His lips pull up into a smirk at your body's betrayal of how close you are.
With a final flick to your nipple, his mouth releases it and kisses up your neck to your lips. He holds you against his body, making sure you can't escape from the pleasure, and greedily swallows every moan. As your high nears, you tighten your grip on him and rock your hips back and forth against his fingers, needing to have him get you off. At last, with a loud moan, you reach your climax and clench your thighs tightly around him.
As you come down, Jooheon gradually slows the pace at which he rubs you. His left hand slides up to the nape of your neck and pulls you in for a kiss. After he breaks the kiss, he rests his forehead on yours and looks as deeply into your eyes as the darkness allows. His fingers still slowly toying with your over-sensitized bud send spasms throughout your thighs and torso.
You release your hold on him and run your fingertips along his chest down to his throbbing dick. At first contact, it twitches against you. You search with your thumb in the darkness between your bodies for the slit and smile when you feel his precum already oozing out. With your thumb you spread it all over the head, then you spit on it and work your saliva down his member, gradually jacking him off as you do. Contented vocalizations escape him.
You know now is the time. Your hands abandon their positions and push him back slightly. You jump down off the desk and kneel in front of him, becoming eye-level with his hardness, swiftly slipping him into your mouth. First, you swirl your tongue around the head, then around the shaft, earning you a quiet yet satisfying moan.
After about a minute of slowly sucking him, you slip him out and lick up the shaft with just the tip of your tongue, starting at the base, and ending at the tip. You rapidly, yet delicately, flick your tongue along his slit, then twirl your tongue around the head again. His eyes had been closed, head tilted back, but now he eyes were focused on you, watching every motion.
This attention excites you and you take advantage of it. You lower your head and run the tip of your tongue slowly across his balls. You do this a couple of times, and then you suck the left one into your mouth and suck on it for a few seconds before releasing it with a loud, wet pop. Then you turn your attention to the right one and do the same.
As he's watching you, his face is riddled with disbelief at what he's seeing you do, but also with pleasure and a desire for you and whatever else you may do to him. Before he knows it, you're sucking both of them into your mouth at once and running your tongue over them. More quiet moans leave his lips. He continues watching you as you release his balls from your mouth.
The way you're both facing, the desk is now at your side, and the light from the open door now shines on both of your bodies. In this position and lighting, you can finally take in the entirety of just what Jooheon is blessed with. You once again lick up his shaft and swirl your tongue around the head. He inhales sharply and sighs at the sensation of being inside your warm, wet mouth.
"Mm, I didn't think your lips could look any better than they usually do, but they look insanely hotter when you wrap them around my dick like that."
You smile and blush at his words, trying to focus your attention instead to bobbing your head up and down on his dick, slowly at first, making sure to coat him with your saliva. Each time you go down, you go a little bit further down on him until you reach your comfortable limit. After you've thoroughly coated him and massaged him with your tongue a few times, you close your eyes, relax your jaw and become more focused on pleasing him.
Out of nowhere, you hear a hand practically slam onto the desk. You look over and find his left hand fumbling around trying to get a grip on something, anything, to help him keep his balance. His right hand comes up to rest your shoulder, then to the back of your head and you continue your work. Up and down, up and down. He's caught off guard when you suddenly decide to slide him in as far as you can, controlling your gag reflexes as much as much as possible. A loud moan escapes him in such a way that you can tell for that split second he had no control over himself, making your body ache with need for him.
Feeling satisfied with yourself, you slide him back out just to your comfortable limit and suck some more. You surprise him once more, hoping for the same reaction as before.
"Fuck," he hisses. "Stop! Stop, I'm gonna cum," he pants. "While I would love to cum all up in that amazing mouth of yours, but what's fair is fair and you've been having too much fun."
He helps you stand up and crashes his lips into yours. His lips, his hands, everything is basically on fire, which was crazy because of how cool your office tends to be. You melt under his kiss and his touch as his lips make their way down you neck.
When he's done toying with you, he lifts you up onto the desk where you both carelessly push everything on it to the floor. He kisses your lips, down your neck, stopping only briefly at your chest to suck on and tease your nipples, then continues down your stomach. His trail stops as soon as he reaches his target, your swollen, needy clit.
