Hello Chingudeul!

I'm new to this fandom even though I lurked from time to time in the fanfics section. Truth to be told, I was quite reluctant to post my story as I'm not confident in my writing skills... at all! However, my Chingu Taehumama (we're friends, right?) encouraged me to give a try, saying the YoSoo fam needed more fics and so here I am.
So please, if you find grammatical mistakes or vocabulary errors-and I'm sure you will- pretty please let me know it so I can understand and improve my English. All advices are welcomed. Thank you!

Writing this story was quite a challenge as it was difficult, even for me, not to blush profusely. So if you feel uncomfortable about the pairing or sex scenes, please do not read this.

Without further ado, here's the first part of this one-shot.

The twilight's ochre color painted the horizon, from the penthouse's windows one could see Seoul lying at one's feet. The capital was busy as usual however the beautiful view was lost on the woman, standing before one of these windows, as she was deep in thought.

"It's too late to have second thought." Came a voice behind her.

Hae Soo made no move to turn around and thus missed the narrowing eyes of the man behind her. He silently scanned her lithe form, she wore a white blouse paired up with a grey high-waist pencil skirt.

"We cannot go on like this." She whispered.

"What?"

"We need to stop!" She spoke louder.

"What do you want to stop?" He drew near her in three strides, she immediately felt him hovering over her and the butterflies fluttering in her belly. "What do you exactly want to stop?" He sucked onto her earlobe, sending shivers down her spine. She stepped aside, meaning to escape his overpowering presence, only to be flipped around by a smooth move on her wrist. "You want me to stop this?" He seized her slender waist, pulling her closer so that her body mingled with his.

Hae Soo closed her eyes as she felt his growing hardness pressed against her. Hands clenched into fists on his chest, she tried to push him away, the action didn't faze him though as he tangled his fingers up in her long hair instead. He sucked onto her other earlobe, then his mouth went lower along her neck, biting her skin sensually.

"Or this?" He captured her lips, his tongue finding hers and exploring her mouth thoroughly. Minutes later, breathless and giddy she broke the searing kiss. He wasted no time in ripping her blouse apart, freeing her breasts coated in a black bra, he skillfully uncovered it. The view aroused him as she saw the sparkle in his eyes when he looked at her. "Or you want me to stop this?" His mouth avidly went to one of her breast while he was fondling the other, playing with the hard nipple.

Soo could almost melt under his touch, tangling her fingers in his rich black hair, she unconsciously brought up his face so that he took possession of her lips again. He smirked as she tentatively unbuttoned his royal blue shirt, with trembling hands she let the fabric fall on the floor. She breathed out an heavy sigh as her hands shyly reached out to caress his muscular chest and then traced every tab of his abdomen with her index.

"Can you stop?" He taunted while teasing her breasts with skillful hands, with nimble fingers he caressed her side down to her waist. He then unzipped her skirt and let it slide down on the floor, showing black lace panties. Pressing her body against his tightly, he caught her up and carried her onto the nearby sofa. He tore her panties in a wild move and watched as she cowered in stupefaction. He quickly unzipped his black trousers, leaving him in his black boxers only.

Heart beating fast, Hae Soo wanted to flee but he was faster as he grabbed her ankle, pulling her toward him. "Wang Yo-ssi..." she yelped. His dark eyes intently bore into hers, the possessiveness she witnessed, frightened and excited her at the same time. "Do you think you can escape me?" Spreading slowly her legs, he gripped firmly her tights as he went to taste her wetness.

"Oh my..." She breathed in, grabbing a handful of his hair. The man was certainly a good kisser but what he did with his tongue to her lower-body was sinfully marvelous. He intentionally stopped his ministrations before her climax point, "Wang Yo-ssi!" she moaned with desperation. With a wolfish smile he looked up at her eyes, blurred by hot passion.

Yo rose to his full height, got rid of his boxers and allowed her to see his full erection. The young woman's eyes grew wide in expectation. He was hard and ready for her. He stalked over her on the sofa, easing her down against the cushions and melding his needy body onto hers. He licked her throat upward, his hot breath tickled her ear, "tell me to stop... now." He would be merciful only this once.

Soo laced her hands around his neck, forcing him to gaze into her doe-like eyes and she begged, "please..." He tilted his head in feigned ignorance, "please what?" She half-bit half-licked her lips, "please." His feral grin returned, "please who?"

"You." she confessed and his gaze darkened dangerously. He kissed her hungrily while sliding two fingers in her, she was still wet and willing. "Don't ever forget." She moaned louder.

"You're mine." He spread her tights, positioning himself at her wet entrance, his dick tightened in anticipation and then he thrust her in one swift motion.

Yo covered Hae Soo's muffled cry with his own mouth, easing her senses as he stilled, allowing her to adjust to the feel of him. She was tight, so tight that he almost spilled his seed right the moment he entered her. After a few minutes he started to move, sending electric waves down her toes. "Oooh", she whispered in delice. Propping on his elbows, he caressed her hair and mindlessly kissed her, the tension in his cock gripped him hard.

"Faster." Soo begged between kisses, she felt the growing feeling in the pit of her stomach. His manliness filled her and he thrust her harder. Faster. "So close." Feeling the familiar warmth in her belly, she clenched her inner walls, almost making Yo release then he growled and with both hands he gripped her waist hard, "Who's your man?"

"Aaah" Her body was on fire, the torture was killing her softly. "Who do you belong to?" she heard him demand again while he trusted her deeper. "You. Wang Yo." She cried in ecstasy as she felt her climax wash over her body. His smirk went wide as he pounced at her twice before reaching his own pleasure and spilling his hot seed on her flat stomach. His body comfortably blended onto hers afterward. Soo closed her eyes in bliss, he then pressed a gentle kiss on her swollen lips. "Mine, in this lifetime."

Yo fondly looked at the woman before him. Soo only wore his blue shirt and her panties, knees against her chest, she was sitting on the sofa immersed in her thoughts. Fully dressed, he came closer to her with a mug of coffee in each hand, he placed one cup into her hands and took a sip from the other.

"I will tell him." Yo informed, he watched as she raised her head in worry.

"Wang Yo-ssi!"

"After all this, you're still using honorifics?" He said raising one of his eyebrows. She had the gall to blush prettily. "I cannot do this to him."

"Why? Because it's my brother?"

Embarrassed, Soo could almost bury herself in a hole. "Wang So-ssi is a nice man."

"And I'm the bad guy, I suppose... too bad, your body doesn't lie even if your mind still rile up against it."

"I'm almost engaged, for Heaven's sake!" she snorted, making the coffee wave in the mug.

Wang Yo sat leisurely on the sofa next to her, "One more reason to tell So and make a clean cut."

"Are you kidding me? How can you expect the matter to drop off while you are brothers?" Soo asked him in disbelief, she had to drink her coffee in order to calm her trembling hands.

The man gave her his sexy stare, the one she couldn't resist, "it's not like I have a fondness for So. I rarely meet him so you wouldn't meet him either after that."

"But still-"

"I will just be the bastard that stole his brother's girlfriend... that's all." He handsomely smirked.

She didn't want to put him in this situation. She was also at fault. "I will tell Wang So-ssi myself."

Yo narrowed his eyes in suspicion but stayed silent, observing Soo as she picked her clothes up on the floor and strode off.

-Months ago-

When her best friend Jung invited her to his 25th birthday's party, she would've never expected to meet the whole Wang family. That evening, she was introduced to Jung's parents, Wang Geon and Soo Yeon -nice people and clearly happily married. Then she met his calm and timid brother So. The sparks had flied immediately, they had discussed all evening, finding similar taste in common things. Everything was perfect so far.

Jung's older brother came in late but was still introduced to her. "Soo-ah, here's my older brother, Wang Yo."

She looked at the man standing next to her best friend, he wore an expensive black tuxedo, was taller than Wang So and truth to be told, he was far from being ugly despite his cold eyes. Soo bowed, "Nice to meet you."

"Hyung-nim this is my best friend, Hae Soo." Jung added with enthusiasm.

Wang Yo's eyes scanned the petite woman in front of him, doe-like eyes in which one could lose himself, she wore a pale rose lace dress. She seemed already infatuated with his younger brother. Critical eyes darted from So to her, he then lifted an eyebrow, "thanks for taking care of Jung-ie."

"Not at all, it's rather the other way around." She answered, noticing that Wang Yo's gaze still rested on her. It was the case throughout the evening, even when she talked to Jung, So or his parents, Wang Yo always surveyed her from afar. His stare had rattled her during the whole party and yet she couldn't help but feel conscious of him.

Later that night, when she went back to her car, Wang Yo was leaning against it. "You're not meant to be with So." he said coolly.
