A/N: Good afternoon everybody. It's been a while since I have ventured into fanfiction. This story is YAOI, so, if you are not a fan, please kindly switch windows now :) Yaoi is basically boyslove, with explicit sexual scenes.

This is my first story for Koisuru Boukon, a rather fantastic yaoi manga revolving around two main characters: Tatsumi Souichi, a doctorate student of Nagoya University who is bad- tempered and bad-mouthed but has a kind heart, and Morinaga Tetsuhiro, Souichi's junior (kouhai) who has harboured a 5- year- long one- sided love for Souichi.

This story picks up from where the manga ended (Chap 8, where Souichi finally admits his feelings (not the 3-word kind of confession though, but still). So beware, spoilers ahead!

PS: Throughout the story, the way in which the 2 characters are called will switch between these:

Tatsumi Souichi: Souichi (in his own POV) / Sempai (in Morinaga's POV)

Morinaga Tetsuhiro: Tetsuhiro (in his own POV) / Morinaga (in Souichi's POV)

Disclaimer: Koisuru Boukon and all mentioned characters do not belong to me.

Please enjoy this :)

Chapter 1: Stay by my side, always

"Sempai, hold on…"

Souichi had to stifle a gasp, his breath escaping in tiny pants as Morinaga, already pulsing inside him, lifted him gently into his embrace. The delicious friction increased the heat within him and Souichi could not resist the rotation of his hips, his insides rubbing against Morinaga's cock as Morinaga shifted him into a sitting position on his lap.

"Wai—what are you doin—ahh…" Souichi could not contain his moan this time as the new position allowed him to fully sheath Morinaga, the full length of his shaft stretching and probing Souichi in waves of pleasure-pain. Souichi felt Morinaga's large hands surround his hips and butt as he gently maneuvered their movements, and Souichi saw splashes of bright colours in the midst of passion as they began to find their rhythm.

"Move your hips like this, and try to relax further," Morinaga coaxed gently, although the excitement of feeling Sempai so fully was making his voice taut. "Sempai, you feel so good, so tight…" His hands tightened around Souichi's hips as he began to thrust up, meeting Souichi halfway. "That's it, ride me Sempai. Show me what you want to do. Show me what you want to feel."

"No…way…this kind of…" Panting in exertion, Souichi nonetheless began to slide himself up and down, groans escaping unnoticed as the wicked heat began to build up again. The pain was seeping away as their tempo increased, Souichi's nails scouring Morinaga's back as he rode him. A tingling was starting at his spine, and he felt his balls tighten as his cock rubbed against Morinaga's skin with every bounce and thrust, drips of precome beading rapidly. Beneath him, Souichi could feel Morinaga straining as he thrust deep and sure into him, the sweat rolling down his chiseled chest.

"Sempai, thank you, I'm happy". In between gasps, Souichi heard his kouhai's words and he looked down at Morinaga, those soulful eyes capturing him in their depths. Souichi felt his breath catch, even as another thrust caused him to clench down involuntarily. Steadying his voice, Souichi tried his damnnest to sound unaffected as he looked back into Morinaga's olive eyes, "For what…?"

"You have accepted me…" Another thrust, and Souichi arched his back while Morinaga grazed his nipple greedily, sucking and tugging, his breath warm on Souichi's skin. Souichi shivered as Morinaga sprinkled kisses upward and his pulse jolted as Morinaga placed a kiss directly over his heart. "For the first time, I feel like I have become one with the person I love".

"You…" Words flew from his mind as Morinaga plunged deeply, the tip of his cock pressing into Souichi's prostrate. The scream of pleasure came out strangled, mixing and mingled with his groans as Morinaga began to move faster. Urgency caught, Souichi clenched down on him, coaxing a half- shout from Morinaga as they began to move faster and faster, the throbbing and pulsation deep within them culminating in an explosion of heat and pleasure. Warmth began to spread within Souichi as Morinaga gripped his hips painfully, head tilted back as he rode the waves. Within moments, Souichi felt his own cock tighten and then begin to spurt. Panting and shivering as their orgasms undulated throughout, Souichi pressed Morinaga close, inhaling the pine fragrance of his hair as he tucked him beneath his chin. "You are an idiot. It's nothing to cry over…"

The clock chimed twelve in the living area, quiet as Souichi sat in Morinaga's embrace, the two of them getting used to this new- found intimacy in their own ways. They had never cuddled before after sex and Souichi had to admit that Morinaga's chest felt nice as he surreptitiously leaned backward; the brat had exhausted him. He was saved the act as Morinaga hugged him tightly and Souichi did not even have to turn back to feel the happiness that was radiating from his kouhai. Silly puppy. He tried to ignore the warmth in his own chest as Morinaga placed a soft kiss on his head.

"There is something I have to talk to you about, Sempai," The silence was broken when Morinaga spoke aloud, and Souichi shifted, tilting his head to look at him. The post- coital haze was dulling his senses, making him feel sated and calm. "Something to talk about?"

"Umm, it's about the job offer." Morinaga hesitated and Souichi sighed, starting to shift out of the younger man's arms. He was still sore that Morinaga had not told him first about the job offer from S Pharmaceuticals. The younger man's arms tightened, preventing him from escaping. Souichi turned away from Morinaga.

"You are finally spitting it out, huh. I know about it, you are going for an interview right?" Souichi tugged his hand free from Morinaga's grasp, the irritation brought up by this topic fuelled by the fact that he did not know why he was bothered in the first place. Not like he had the right to demand that he be first in every decision that Morinaga made…

As usual, Morinaga hit too close to home. Souichi yelped as Morinaga grabbed his middle and basically tackled- hugged him. "Sempai! Please don't misunderstand ok! That time, when Prof. Fukushima told me about the offer, things were still awkward between us… I was desperate… and then you told me to stay by your side…I started to become undecided again… I did not mean to hide it…I was just thinking…I am sorry."

Souichi sighed and stopped resisting the hug, his hands coming to rest atop Morinaga's. He had told himself that whatever Morinaga did was none of his business but the explanation had soothed his irritation nonetheless. "So, what do you plan to do?"

"I… think I'll try the job."

Which was the rational choice, and Souichi approved of Morinaga's decision even as he knew that this meant that Morinaga would not continue his Master's program at the university. But with S Pharmaceuticals, Morinaga's future was set and that was definitely more important than the minor issue of losing Morinaga as his lab assistant. Besides, that did not mean that he would not see Morinaga anymore, they were living toge—sharing a residence together, after all.

"I see. When's the interview?"

"Ehh, next week! But Prof said that it's just a formality. They have already sent me a training schedule. But training takes place in Tokyo. I'll be away from Sempai for too long!" Morinaga huffed and snuggled closer to Souichi. Souichi imagined a puppy with his tail between his legs.

"Idiot! Tokyo is just a train's ride away. You can always come home. I'll be here, I'm not going anywhere…" Souichi fervently wished that his face did not feel as red as it seemed. He made to stand up, legs wobbling as his hips gave a sharp twinge. "I'm going to bed. Goodnight!"

"Sempai!" Souichi was turned around and his lips captured for a long kiss before Morinaga hugged him tightly. "Sempai, I'm going my own way but I'll never leave you. Please, let me stay by your side, ok?"

Of their own volition, Souichi's arms encircled the younger man's waist and pressed him gently to himself. "Idiot. Do whatever you want!"

Later in the night, with Morinaga somehow managing to weasel his way into Souichi's room and was now deep in slumber beside him, Souichi glanced at his wayward kouhai who had caused him so much trouble. He did not want to admit it but he could see what the many girls in the lab always cooed over whenever Morinaga appeared. His kouhai, despite being a strapping twenty- four year-old, had the round, innocent eyes and pouty lips of a cherub. Add to that his soft, brown locks and his eager-to-please personality and there was a puppy in human form. A tenacious puppy, and Souichi could vouch for that.

Really, when had this entanglement with his kouhai started? Souichi could not recall when and where he had first met Morinaga but he did remember that horrible night five years ago when a trusted professor had cornered and damn near raped him in the lab. Morinaga had come to his rescue when Souichi had been too shocked to push the professor away. It was lucky that Morinaga had come; Souichi might have poked the eyes out of the professor once he regained his senses. Souichi had been convinced since then that homosexuals were evil beings that always harboured such dirty thoughts.

That was the start and since then, Morinaga had signed up as his lab assistant, a valuable one who proved his mettle in the sciences. He had followed Souichi around, going for lunch and often dinner together, asking for Souichi's tutoring for an agriculture module and staying with Souichi until as and when the experiments on hand ended. Souichi had to admit, he had had a soft spot for this persistent kouhai of his. Souichi found himself stroking the younger man's hair as he lay deep in thought. The brat always worked himself to the bone for tasks that Souichi had assigned him, and had even fallen ill when Souichi had taken off to Tokyo to rescue his younger brother, Tomoe, from the hands of his evil, gay landlord. Souichi had visited his kouhai, the first time he had shown concern for another person other than his family. Without a doubt, Morinaga had become a steady presence in his life.

Morinaga's confession a year ago had shocked him but, when he thought deeper now, it had not disgusted him. Hell, Souichi had even hopped onto the first train to Tokyo and asked his brother for advice. Advice on how to have a gay relationship! His cheeks still burned at the memory of the conversation outside of Tomoe's university. The advice on using Vaseline had been useful… Clearing his throat even though he was the only one awake in the bedroom, Souichi closed his eyes, lulled by the steady breathing of Morinaga. Since when did Souichi stop thinking that all gays were evil? It was certainly not because of his brother's husband (Souichi would still gladly throttle the man to death). Since when did Morinaga worm his way through his defences, to the point that he would have sex with another man? Since when did the mere thought of losing Morinaga become unbearable? Souichi was still adamant that he was not a homosexual. However, as he began to slip into sleep beside the younger man, fingers still resting on Morinaga's head, such labels did not seem to matter so much anymore.

To be continued.
