Chapter 4

Tatsumi was working in the lab one afternoon when there was a knock on the door and Professor Fukushima came in. He was running behind on some tests and had been trying to catch up.

Morinaga was in Hamamatsu again and Souichi was finding it difficult to keep on top of things in the lab.

"Tatsumi-kun, how are you doing today?"

"Hello Professor," he answered distractedly. "The tests are going as well as can be expected. I'll be able to get the findings to you by the end of the week."

"That's fine, just fine," he smiled. "Have you been able to find a new lab assistant?"

"Not yet," Souichi grimaced. "My reputation has preceded me and no one wants the job." He scowled, "I reap what I sow, I suppose."

"Well, I don't know about that," the professor said smiling gently, "but I have a third year student who needs some extra lab credits and she would be willing to help you out."

"Really? What's the catch?"

"No catch," the professor laughed. "I think you two might get along and your fields of study are compatible. I know how hard it's been without Morinaga-kun and I believe you two could make a pretty good team."

"Ok, send her over and we'll see."

"Actually she'll be here in about ten minutes. Why don't you take her to dinner and talk it over. You will both be better able to decide after that."

"Professor! Don't you think that's a bit sudden? I'm not done here yet."

"Just go take a break. Knowing you, it'll be the first meal you've had all day." A knock sounded on the door, "Come in Sawanoi-chan! Let me introduce you."

A young woman walked into the lab. Souichi noticed that she barely came up to his chin. She was petite with very wavy chestnut hair and very blue eyes. 'I wonder if she's wearing tinted contacts,' Souichi thought. 'She's too cute to be serious about the work,' was his second (very unfair) assessment.

"Tatsumi Souichi, this is Sawanoi Nagomi," the professor introduced them. "She's one of my top third years, so behave," he winked and smiled at both of them and was gone.

"So, senpai, does he always do that? Blow in and then out again?" she laughed.

"He's a very persistent man," he replied with a scowl. "He wants us to grab a meal and talk this lab thing over, are you interested?"

"Of course Senpai," she answered with a bright smile. "Shall we go?"

Souichi was walking home after work was finished that night and he had to admit that the professor had been right. Sawanoi had a brilliant mind and quickly grasped what Souichi was trying to prove in the lab. 'She's no Morinaga, but she'll do,' he thought, pleased. 'If only she acted just a bit more serious, she's so flirty and playful. That could become annoying.' He felt slightly uneasy but he chose to ignore it. 'I wish Morinaga was back, I'd like to discuss her with him,' he sighed. During their enforced absences, Souichi missed seeing the younger man. Of course he would never admit it to Morinaga; his pride wouldn't let him.

He thought back. It wasn't like this was his first relationship; it certainly wasn't his first sexual one (although it was his first with a man!) Back in high school there had been girlfriends – they were few and far between because he'd never been a player. He dated the girls he really liked, not just the ones he was attracted to.

His forays into dating always started out well but the girls got possessive and jealous, demanding more and more of his time. Time he didn't always have. He had his studies – he had to go to uni! And his little brother and sister took his time, too. The girls always came second to his siblings.

After a while he decided that it was easier and just as effective to take care of his sexual needs himself. Jerking off was cheaper: he didn't have to take himself out to dinner, shopping, or a movie in order to get some! By the time he started college he was so self-sufficient, he seemed totally uninterested. It wasn't entirely true, he was a guy after all, but his natural reserve and short temper kept the girls at a distance.

He was actually seeing someone when Morinaga bulldozed his way into his life. After a while it ended; he still had his obligations; that hadn't changed once he entered university. Although this time around it wasn't jealously over his siblings, she was jealous of Morinaga!

At the time Souichi had laughed and shrugged it off. How anyone could be jealous of his kouhai was laughable. Sure he was a great guy and a good friend, but the older man put the younger one through hell at the lab! It was nothing to be envious of.

Since then there had been no one. Outside of his family, Morinaga had been the only other person in his life. Souichi just couldn't see his life without the other man, now even more than ever.

He opened the door to an empty apartment and turned on the living room lights. The place was too big with Morinaga gone. 'Well I guess I'll shower and hit the sack.' The shower was great; he felt relaxed and at peace. He got into bed and turned out the light. Thirty minutes later he threw the covers off as he sat up. He couldn't sleep; forget sleep he couldn't relax. More importantly he couldn't get those damn green eyes out of his head!

Souichi was determined not to miss the idiot; however his body had no intention of letting his mind get away with it. Every time he closed his eyes he saw Morinaga, or felt his hands on his body…or smelled the musky scent that surrounded the younger man like some sort of pheromone-rich aura. Souichi could pretend to be immune when Morinaga was there, it was easy to ignore. However, now that he'd been left alone he couldn't deny the pull the younger man had on him. It was like an addiction and Souichi was having withdrawals.

He lit a cigarette as he got out of bed. He started pacing in the hallway. 'Damn you! Even when you're not around you cause me trouble.' It was easy to blame Morinaga. He was the one who'd turned him into a walking erogenous zone! How dare that idiot make him crave his touch and then go out of town for training? How dare he not come home more often, either! "How dare he not be here when I'm so damn horny!?"

Souichi stopped dead, 'What the hell did I just say?' He looked at Morinaga's bedroom door and sighed as he entered. As he turned on the light he looked around the room. It was so familiar yet alien without its owner. He sat on the bed and grabbed the pillow. As he buried his face in it he thought, 'It's just four more days, I can do this, get through this.' He sighed again as he lay down. He closed his eyes and once again there was Morinaga.

Souichi threw the pillow across the room. He then brushed his hand across his nipples through his pajamas. "Mmmm," it felt good as his hand caressed his chest. Souichi took his shirt off and gently rubbed and pinched them; then he tried doing it a little rougher and it felt wonderful! He tried not to think too much, "Tetsuhiro, touch me, touch me lower," he whispered as his other hand trailed down inside his pants and he firmly took hold of himself. "Ahh, yes, that's it," he imagined his lover stroking him and he imitated what the younger man always did to him. "That's good, mmm…" he groaned. His eyes suddenly popped open; he just remembered what else Morinaga always did to him and Souichi just couldn't go there! 'He did say that to do both the front and back at the same time was more arousing,' he thought as he blushed. "I can't do that!" he whispered. "But…I…ugh!" Before he could chicken out, he quickly went to the bathroom for some cream, made sure all the lights were turned off, finished stripping, and got back on the bed.

"Ok, let's see," as he smeared the cream on his hand, he picked up where he'd left off. He began imagining Morinaga playing with him again, stroking his erection and then he slid his creamed hand to the back. After a little trial and error, Souichi rolled onto his side (it seemed easier that way), and started rubbing up and down the crack to his entrance. He was a bit shocked when he found it! He circled it with one finger and experimented by pressing here and there. When his finger actually went in he gasped in surprise. He started moving it in and out as well as around inside. When it felt easy to him he inserted the second one and continued to apply friction. His muscles started twitching and contracting as he started moving his fingers back and forth, 'I bet this would feel so good to do to Morinaga!' A picture of him doing just that rose up before him and he got even harder. He started panting and thought, 'Next I need to find…ahhh! Ok…found it.' He concentrated on moving both hands in sync and hitting his prostate as often as he could. As the heat and pressure built up, "Ummm almost….Ahhh!" he cried out as he came. He lay there in Morinaga's bed twitching from his orgasm, completely stunned that he'd done it there and like that!

'Shit! Why is it that every single time he's gone, I turn into a giant pervert? When he gets back he is so gonna get it!' Souichi smiled grimly. After he cleaned himself and the bed he lay back down and fantasized about what he'd do to the idiot once he came home until he fell asleep.

A/N: Hiya! I decided it was time to put out a little info for anyone who is interested. This story was my very first fanfic ever and I began writing it last year and posted it on livejournal. It's taken me this long to make up my mind to also post here. :)

I'd like to thank those who are reading as well as those who have favorited and followed, it makes me very happy. I'm not a writer who begs for reviews but I will say here that they are read, replied to, and tremendously appreciated. The main reason for my posting, is to try and help these "children" of mine find an audience. If you enjoy my efforts, I'm satisfied!
