Chapter 1: Tokyo, my love

xxx Souichi xxx

"Sempai!"

Morinaga's excited voice travelled across the crowded platform of Tokyo's shinkansen station and Souichi looked around for his kouhai, a hand gripped securely around his stayover bag. The late November air was cold and crisp and his breath came out in white puffs as people filed neatly if hurriedly towards the escalators. Finally, through a group of businessmen all dressed identically in dark coloured suits, Morinaga's tall and lanky form approached him, all one hundred and eighty- five centimeters of adoration.

"I missed you! I can't wait to show you the apartment!"

Souichi was suddenly caught in a tight embrace. Even through the thick layers of their parkas and sweaters, he felt a heated jolt travel through him as their chests collided. Morinaga's bare collar peeped out from beneath his jacket. Held close to him as Souichi was, the piney scent that was so distinctly Morinaga's pervaded his senses. Ah, Morinaga smelled so good...Before Souichi could control himself, he had leaned in and pressed his lips against the invitingly warm expanse of Morinaga's skin.

"…S-sempai? What are you…doing?" There was surprised pleasure in Morinaga's voice and belatedly, Souichi shrugged off Morinaga's hands, mortified that he had forgotten that they were in public. Some curious glances from that group of businessmen swept their way and Souichi's cheeks now burned for entirely another reason.

"N-nothing! I did nothing! Come on, let's go!" Flustered, Souichi stalked towards the escalators and did not even notice when Morinaga took the bag from him. Ah, what the hell had gotten into him just now? It could not be that he was…craving for Morinaga's touch, could it? He shook his head violently. Of course not! The last few nights of restlessness when Morinaga had been in Tokyo meant nothing! "Woah-!" He jumped when a hand closed over his arm and Souichi flushed when Morinaga looked taken aback.

"Ano, Sempai—we have to catch the subway in this direction to our new house…are you feeling all right?" Concern flooded the other man's voice and Souichi grimaced and nodded. No way was he going to tell Morinaga the truth!

The subway platform was even more crowded and there was a snaking line at every gate as the train slowed to a stop. Souichi felt Morinaga's arms hold him securely as the gates opened and exiting passengers jostled roughly with those eager to board the train. Instinctively, Souichi's hand went to the front of his jacket, shielding his belly from being bumped into as the crowd surged into the train.

Miraculously, they managed to secure seats in the middle carriage and Souichi sighed as he settled into the hard plastic seat, hearing Morinaga do the same beside him. The train lurched slightly as it left the station and began to pick up speed. "I should have thought of the crowd and ordered a taxi for us, Sempai…sorry!"

"Silly, what are you apologizing for? I knew Tokyo was going to be like this. If I were to take a cab wherever I went, it'd be too expensive. We still have the renovations to think about."

"But—"

"Ah, the apartment should be near your company, right? Since the accommodations are provided by them." Souichi deliberately changed the subject and he heard Morinaga sigh again. Silly puppy; he was treating Souichi like spun glass as the pregnancy progressed; prohibiting him from carrying things that were not even heavy and escorting him around whenever he had gone out for exercise or grocery shopping back in Nagoya. A week ago, just before he had left for Tokyo ahead of Souichi, Morinaga had gone as far as forcing Souichi to stay at Matsuda- san's home until he joined him in Tokyo. It aggravated him to no end but Souichi had ultimately acceded to Morinaga's request, not just for his own peace of mind but also for the well- being of their baby. The memory of their near- loss from the lab accident was etched into his skin.

"Yea, it's a ten minute walk to the company. The people there are really nice, Sempai; arranging for the new apartment to be leased and ready for us within two weeks! You should see the bedroom; it's linked to another smaller room that we could use as the nursery! I'll bring you to the shop that I told you about; there was this baby crib that…" Morinaga's voice, subdued at first, gradually rose in excitement as he chattered on about the renovations plan for their apartment.

It was twenty minutes and a short walk later that Souichi had the first glimpse of their new home. In a quiet residential district where cherry blossom trees were planted plentifully on the road median, they walked to the second house of a row of elegant, two- storey apartments. Souichi admired the clean, minimalist exterior of the buildings as Morinaga took out a keycard and deactivated the door lock.

"Sempai, welcome home."

Morinaga's tone betrayed his happiness as Souichi entered the house behind him, his loafers tapping quietly against the beachwood floor. This apartment was much bigger than their current one in Nagoya. The short hallway opened up into an inviting living room where a plump couch and a large LCD television sat beside a wall lined entirely with bookshelves. Souichi's bare feet sank into the cream carpet as he approached the wood- and- glass bookcases, noticing that most of his agriculture textbooks were already placed neatly in alphabetical order. Morinaga's books and manga had also been arranged nicely beside his. The alcove beside the shelves let in natural light with the large window and Morinaga had placed a wooden desk there, the desktop computer that they had bought recently already plugged in and ready for use. From the arrangements, Souichi could tell that Morinaga had put in effort to create a working space that was convenient and spacious for him to work from home. They drifted towards the kitchen next, where he saw that all the appliances had also been cleaned and installed for immediate use. Morinaga had done all the work in the one week that he was here.

"Sempai, sempai; this is the room that I thought would be nice as the nursery! We could place the crib over by this wall and a cupboard for the clothes over here…" They had ascended the stairs to the second floor and entered the last room on the landing. This room, like the rest of the house, had strategically placed windows such that the sunlight could filter in and he immediately felt a calming vibe as he stood in the middle of the square room. Following Morinaga's words, Souichi could visualize what the man meant as he excitedly pointed out to the areas where various furniture could go to.

The nursery was the only room that had not been furnished. Morinaga had aired out the room to dispel the remaining fumes from the fresh paint but they had agreed to go shopping for the baby together. The room was thus empty, save for the bags of clothes and toys that Morinaga had bought sporadically the past few weeks. Even so, there were already a significant number of purchases. They still did not know the gender of their baby but the silly man had gone ahead to buy clothes for both genders anyway, much to Souichi's exasperation. Nonetheless, he could also feel the bubble of anxious anticipation as the days passed. He was almost twenty- four weeks along and not even his parka could totally hide his condition now.

Three more months to go, huh. Through the woolen material of his sweater, Souichi felt a kick against his palm as he rested a hand on his firm belly. The memory of Morinaga's awestruck expression when he had first experienced their baby's movement in Souichi's womb made him smile inwardly. They had really come a long way since the beginning. He could still hardly believe that he was here, standing in the nursery of their new apartment with his kouhai, a baby due in a few months and his postgraduate programme halted in Nagoya University in favour of moving to Tokyo for Morinaga's work. Everything that Souichi had planned for his life since he was a teenager had been uprooted and utterly changed and it was due mostly to the insufferable man standing not three feet away from him.

But was he unhappy? His own answer was wiped from his mind as he felt Morinaga's arms wrap around him and pull him in for a kiss. Souichi opened his mouth to receive him, his body immediately reacting to the sudden close proximity of his partner. Morinaga's tongue swept through his mouth and Souichi shivered as jolts traveled through his entire body. The front of his trousers tightened as his member came alive all at once. Oh shit, he had an erection just from a kiss! Pushing the other man away in mortification, Souichi's efforts only caused him to rub against Morinaga accidentally and a moan escaped from his lips. "Morinaga, let go!" Turning his head away to hide his embarrassment, Souichi renewed his struggles and tried to ignore the heated throbs that were becoming painful.

"Sempai…"

"I-idiot! What are you doing; put me down!" Could this get any more embarrassing? Souichi was held prisoner in Morinaga's arms as the man swiftly opened the door to the linked bedroom beside the nursery. Souichi did not even have time to look around as he was pressed against the wall, his maternity trousers easily pulled down and Morinaga's hands palming him against his wet briefs. "Hah—hh! Morinag—a! Stop! Hn—nn!" His hand rose and grabbed hold of his kouhai's hair as Morinaga swallowed him, his hips rocking and jerking into the damp heat curled around his shaft. "Ahh!" Souichi jerked violently, sweating and panting as he quickly found his release, Morinaga's hands caressing his pelvis as he sucked him dry. Souichi pushed his head away, his legs weak from the exertion.

He had come almost the moment Morinaga had put him into his mouth! Souichi could not remember the last time he had become aroused so easily. The bastard was definitely going to take advantage of the situati—"Morinaga—wait, what are you doi—ahhhh!" Sharp pleasure rammed through him as Morinaga drove into him in one thrust. "Nnn, nnn…ahh! Morina—ga!" Souichi's elbows pressed against the wall, his swollen belly heaving as Morinaga took him from behind. Errant hands slipped beneath his sweater and began to knead at his chest and nipples. Souichi quivered from the delicious friction as Morinaga gripped the sides of his belly, the rough pads of his fingers chaffing against the sensitive skin of his womb. "Wah—ahh!' He was pulled roughly backwards as Morinaga thrust forwards, his cock buried deeply in Souichi. The sensation of being invaded so fully was Souichi's undoing. His sweat- slicked arms slithered against the wall as Morinaga plunged faster and harder into him, his aroused cock bouncing upwards with every thrust. "Morinaga…I'm coming—I'm coming! Ahh—ahh—ahhh!"

The couch was extremely comfortable but Souichi's hips were complaining so badly that he could not relax fully into the downy goodness of the sofa. He turned and scowled at Morinaga as the man, freshly showered and in apparent high spirits, brought a tray of raspberry leaf tea to him.

"Sempai, drink the tea while it's hot!"

The man was all smiles as he settled down beside Souichi and the long- haired man had the overwhelming urge to smack that shit- eating grin off the younger man's face. He knew exactly what was running through Morinaga's gutter-filled mind. They had done it two more times afterwards, moving to the bed when the weight of the baby had proven too taxing on Souichi's hips. Morinaga had had to wipe the bedroom wall afterwards and Souichi's cheeks burned at the heated memory. This was not the way that he had imagined christening the new house!

Morinaga's lips were suddenly pressing insistently against his and his mouth opened out of reflex. It had to be the hormones, Souichi thought hazily as he leaned into the kiss. There was no way that he could be so addicted to Morinaga's touch...

"I've missed you, Sempai. I'm so happy that you are here, now!"

Even though Souichi had participated enthusiastically himself, there was no way he was going to admit that! "B-baka! That was no excuse to jump me in broad daylight!"

"Ehh-? That's unfair, Sempai! You were the one who got me excited! That face of yours when you—"

"Morinaga!" His hand shot out to cover his kouhai's dirty mouth. The man had the cheek to kiss his palm and Souichi immediately retracted his hand, face flushed. It was definitely the hormones' fault! He had read the medical journals; knew that increased sex drive was one of the possible phenomena during the later months of pregnancy but he had never known that as a man, he would be affected by the changing state of his body due to the baby. This was dangerous, considering how Morinaga always seemed up for it...Souichi's hips gave a twinge, as though in agreement.

"I'll give you a backrub tonight before sleeping, Sempai. That would help to alleviate the pain, ne?"

Morinaga's hands glided over his hard belly and Souichi sighed. There was no use getting angry over what had already been done and frankly, enjoyed. So long as he kept himself and Morinaga in check, there should not be any problems, right?

That night, they did it again on the couch to the muted sounds of the television.

To be continued.
