What does Grissom think? What does Grissom feel? What does Grissom want? Not a clue. Not a chance to find it out. Out in the field as a CSI trainee, with Grissom supervising me. But we won´t be alone. We will be surrounded by people and Grissom will never ever give the slightest impression, that there is something more between us than work. In fact, he will act, if there wasn´t a case, he wouldn´t tolerate me at a Crime Scene.

Even worse, he would never do the same, as he did in the dark room. Alas! It seemed happening a long time ago. Since then, my desperate longing for Grissom´s touch had grown. I feel so restless. So unfulfilled. On top of that, Grissom is acting as nothing had ever happened between us. Apparently, he never kissed me, he never touched me. I´m that close, begging him. Take me, please. Do whatever you want with me. I´m going crazy here.

"Greg!"

"Huh?"

"I asked, if you are nervous?"

"Why should I be nervous?"

"It´s your first day out in the field."

"My fourth."

"What?"

"It´s my fourth day."

"Come on. You can´t count the other trips, nor the already famous soda bottle adventure. Today is your genuine first day as a CSI trainee."

"Fine. Whatever. But why should I be nervous?"

"Because of Grissom."

"What? What do you mean? Why should I be nervous, because of him?"

"You want his approval. You need his approval. You live for his......."

"Cut it out! I don´t go out in the field to get Grissom´s approval." Dear God, I DO.

"You don´t?"

"No. Why do you think that?"

Nick shrugged his shoulders. "You adore him and you have great affection for him. During the last weeks it showed more than ever."

Greg blinked. "Sure, it´s true. But, can´t I say the same thing about you?"

This second, they arrived at the scene. A female body was found in a house in the suburbia of Las Vegas. Caucasian, in her thirties, long dark hair, multiple stab wounds all over her torso. The body was already on his way to Dr. Robbins.

Grissom was standing outside, waiting for them. He looked quite impatient, almost like always.

Greg and Nick grinned at each other. They got out of the car.

Grissom frowned. "What are you grinning about?"

"Nothing!" Both shouted.

Grissom didn´t look quite satisfied. Even so, he came right to the point. "Nick, you and Greg will search for evidence around the house. Be especially careful with the collecting. The new sheriff ordered us so." Without waiting for Nick´s answer, he turned his attention to Greg. "Well, Greg...it´s your first day as a CSI trainee. I want you to take it slow. Stay in the back, listen and learn. If Nick or one of the others gives you an order, do it."

"Oh, a dream comes true," Nick joked.

Not at all offended, Greg grinned very friendly at him.

"Understood, Greg?" Obviously, Grissom wasn´t in the mood for jokes.

Immediately, Greg was eager to soothe him. "Sure. Every word."

"Is there something else, you wanna ask me?"

Oh yes. There are so many things, I wanna ask you. It´s a pity, it´s not the time nor the place. "No, I´m ready."

"I think so." A shimmer of amusement was seen in Grissom´s eyes. "You wouldn´t be here, if I don´t."

Greg was smiling confident. "I will do my best. Sir."

Grissom frowned again. Oddly, he didn´t disapprove Greg, for calling him ´Sir´. He just turned and went into the house.

"What did you do to him?" Nick asked surprised.

"What do you mean?" Greg responded, still caught in his confusing feelings.

"Lately, Grissom acts different around you."

"In what way?"

"I don´t know. I can´t put the finger on it."

"You´re just imagining this."

"No, I don´t. You are acting different too."

"Nonsense. I really don´t know, what are you talking about," Greg snapped.

Nick silenced. For a while, they focused on searching the ground for blood or any other evidence. But Nick couldn´t leave the subject alone. "It isn´t just you, acting different around Grissom. Lately, you don´t go out much, anymore."

"So what?"

"Are you seeing someone?"

"Beg your pardon?"

"Are you dating?"

"No."

"Somehow, I don´t believe you. Somehow, I think you do."

"I don´t!" Greg shouted angrily.

Just now, Grissom turned around the corner. "Are you finished out here?"

Greg jumped around, startled. Shit! Did Grissom hear what he just said?

Grissom´s expression was calm. But that didn´t proof anything. He was always unreadable.

"Almost," Nick answered.

"Good," Grissom replied. "Greg, come with me please. I´ll teach you a particular lesson."

Still being at a loss, Greg stumbled after him.

The master and his grasshopper, Nick thought amused.

In the house, Greg followed Grissom to a small room. The light was dim. Still musing about Nick´s suspicions, Greg didn´t notice Grissom´s moody face.

Accusingly, Grissom uttered: "So, you are flirting with Nick."

Greg was caught off guard. "What?"

"And you aren´t seeing anyone?" Grissom continued.

Oh my God! His hearing had improved rapidly, was rushing through Greg´s mind. He started to defend himself. "I just...." But he didn´t get far.

Grissom grabbed him fiercely and shut him up. With a bruising kiss.

Greg didn´t fight back. Shaking with surprise and longing, he welcomed the kiss. Giving himself up completely. He opened his mouth to deepen the kiss.

Swiftly, Grissom gave him free and said in a totally businesslike tone: "Take the evidence bags and give them to Nick for storing."

"Grissom...."

"That´s an order!" Grissom´s expression and voice were cold. It frightened Greg a little, and intimidated he walked out as he was told.

Grissom took a deep breath. Dear God! I almost lost control. At a Crime Scene. I´m really out of my mind. Everybody could have walked in here any moment. I have to stop this. Now.

"Here, he ordered me to give you that."

Something in the tone of Greg´s voice made Nick prick-eared. "What happened?"

"Nothing. Why do you keep asking me that? Stop bothering me."

The next second, Grissom joined them again. He gave the image, as he already had solved the case.

In contrast, Greg was looking so uncomfortable, Nick´s curiosity changed to concern. What the hell had happened in there?

"Are you finished?" Grissom demanded to know.

"Yes, we´re done out here."

"Good, Nick. Take the evidence back to the lab and give it to......" Grissom hesitated for a second "....Hodges."

Nick noticed Grissom´s disapproval to give anything to Hodges and grinned.

Greg didn´t. He was staring at the ground. Silent. Something, you had to get used to.

"What are you going to do?"

"The sheriff called me on the cell. He wants to see me."

"When will you be back to the lab?"

"I don´t know for sure. Maybe in an hour. Maybe more. Something important comes up, call me on the cell. Greg will come with me."

Now, Nick was really puzzled. Why didn´t Grissom send Greg back to the lab with him? He threw an inquiring glance at Greg.

Seeing it, Grissom´s voice became pushy. "What are you waiting for?"

"Nothing." Nick left, feeling even more curious.

While getting rid of their latex gloves, Grissom could see, Greg´s hands were trembling slightly. "Still trouble with your hands?"

"Yes." Liar, Greg scolded himself. You tremble, because you´re so nervous right now, you could.....

They got into the car. Grissom started it. "Tell me, what´s wrong?"

"Nothing. Why is everybody asking me that today?"

"Well, let me tell you one reason. For weeks, you were so enthusiastic, for going out in the field. Now it happened and you´re acting so ....different."

"Maybe, I grew up."

"Greg..." Intimate, he laid his hand on the younger man´s knee.

Greg jumped. "Don´t touch me!"

At once, Grissom took his hand away. He looked a little hurt, but didn´t say a word.

Awkward silence followed.

Greg stared out of the window. Soon, he noticed, they weren´t driving in the right direction. "That isn´t the way to the sheriff´s office."

"Really? Clever boy."

"Isn´t the sheriff in his office?"

"Actually, I don´t know, where he is."

What! Greg was totally stunned. "We are not going to meet the sheriff?"

"No."

"Didn´t he call you?"

"No."

Baffled, Greg was silent again. Wow, Grissom lied to Nick. He lied on purpose. Why? He threw a very concerned look at his boss. At his ..... Shyly, he managed to ask: "Where are we going?"

"To my place."

That brisk, but clear answer hit Greg so unexpected, his voice was absolutely muted. His mind wasn´t. To his place. Now. Jeez! This must be another dream. Maybe, I just misunderstood the whole situation. We will go there, to pick something up. That´s it. Sure. No way. My boss is taking me to his place! During work time. It´s about one thing and one thing only. He wants to fuck me. So what? I dreamt about this more than once. I wanna fuck him too. Why am I so nervous? It´s Grissom! For God´s sake. Not some guy, I met in a bar. Oh my God! What the hell shall I do?

Greg didn´t know, that every feeling, he was going through, could be seen in his face. He was like an open book. Even his bottom lip trembled a bit.

Grissom observed him closely. He smiled slightly about Greg´s understandable bewilderment.

No more than five minutes later, the car stopped. "We are here," Grissom told him in a low voice.

Greg looked, as if someone had hit him with a bat. He stumbled out of the car and followed Grissom without even thinking. They could have gone right to hell, he wouldn´t mind.

With caution, Grissom closed the door of his apartment behind them.

Greg, still half in trance, was looking around curiously. Grissom´s apartment, his living-room. Wow! He never believed, he would be ever allowed to come here. Greg couldn´t finish his thought, because he was grabbed and dragged to a door at the back of the living-room. Apparently, there wasn´t any time to waste.

Grissom pushed the door open and there was the bedroom. Rather playful, Grissom nailed Greg´s hands against the wall. "Let´s see, what we get on your list of delicts. Flirting with Nick. Calling me ´Sir´. Shouting at me. You know, what you´re asking for, don´t you?"

"Yes." Greg´s voice was full of hope.

Grissom delivered. "More punishment."

Talking was over. Kissing started. Nothing else mattered anymore. Only this world of lips and tongues and hands. Flesh on Flesh.

Even so, the kiss was just perfect, Greg broke it impatiently. "Touch me, please. I can´t wait any longer. I´ll be coming right in my pants."

"Oh, now you want me to touch you."

"Back in the car? I didn´t mean that." He nestled his face to Grissom´s neck. "It was your fault. You made me so nervous." Tenderly, he licked his skin. "So horny."

Grissom´s strictness melted away. "Mmh. How insensible of me. Maybe that was my intention."

Greg chuckled. "At a Crime Scene? No way. Not you."

Wordless, Grissom pushed him on the bed. In a hurry, he got rid of his pants and shirt. "You have no idea, what I´m capable of."

Greg gaped amazed at him, almost staring, because Grissom stood in shorts before him. "Ready for some special lessons from your supervisor?"

In silence, Greg nodded, eyes fixed on Grissom´s visible erection.

Smiling, the older man laid down on him.

They started kissing again. Hard. Fiercely. Passionate.

Greg whimpered in Grissom´s relentless grip.

At once, Grissom became softer, putting only feather light kisses on Greg´s quivering lips. "Do you really want me to punish you again?"

"Yes."

"Are you certain?"

"Yes. Oh yes."

Affirmed, Grissom opened slowly Greg´s pants, pulling them down. He continued with unbuttoning the shirt. One button after another. He stripped the shirt off. Thoughtful, he was stroking Greg´s pale skin, then the nipples.

Greg trembled visible, while he was feeling more than ready.

"Are you still nervous?"

"Yes."

"Why? I´m certainly not your first man."

"No, but I never been with my boss before."

"Glad to hear it." Kissing Greg´s nipples, he mumbled: "You know, you can always say stop."

"I know, but I won´t."

"So, you will do whatever I demand." It was no question, so he wasn´t waiting for an answer. Instead, he returned to Greg´s mouth, sucking his bottom lip seductively. The response was unmistakable.

Greg wrapped his arms around him and was grinding his throbbing cock against his body. In addition, he freed his lips, pleading: "No more foreplay, please. I need you now. I´m so ready."

"Don´t you dare, ruining my lesson. I´m your boss and I insist on obedience."

With trouble, Greg tried to stifle his laughter. "Oh, please. Touch me, sir."

Smiling fondly, Grissom placed another heated kiss on his lips. "Well, pleading so nicely is getting you what you want." Apparently giving in, Grissom made a wet trail of kisses down Greg´s chest. But he stopped at the nipples once more. Giving them little, gentle bites.

Greg panted surprised and grabbed Grissom´s hair.

In response, Grissom was biting tighter.

Greg was writhing under him. "Oh God, what are you doing to me?"

"A CSI trainee has to take all the lessons. From the beginning. That´s the rule."

Greg gave a groan. He worried, his heart and his cock would burst any second. "Grissom. I...."

Finally, Grissom put his hands on the waiting cock. Rubbing him through the shorts. He felt it was time to pace it up. Easily, he got rid of Greg´s shorts. "I see, testing is over." He tightened the grip around the thick shaft.

"Yes. Touch me. There. Right there. I want...."

"What do you want? Tell me."

Greg´s brown eyes were meeting his blue ones. "Suck me, please."

Grissom could see Greg was near to climax. Playing around was over.

He slid the pulsating cock in his warm and controlling mouth.

Finally! Pure pleasure washed over Greg and he lost himself in it.

Grissom sucked and licked him with much experience. Taking the time to make it good. First, he encircled the sensitive tip, teasing it with his tongue. Again and again.

"More," Greg whispered huskily.

Grissom moved his attention to Greg´s balls, lingering with them. Eating them up.

Greg moaned with more and more pleasure.

Now, Grissom took care of the shaft, licking it slowly up and down.

Meanwhile, Greg´s breath was coming in ragged gasps. He buried his hands tighter in Grissom´s hair, pulling him down on him. Pushing his cock in deeper. "Yes. Faster. Much more."

Fulfilling his desire, Grissom swallowed him all the way down to the root. Up and down. Up and down. Reaching a pure steady rhythm.

Bucking up his hips, Greg thrust wildly in Grissom´s mouth. He couldn´t enjoy his unbearable excitement much longer. Uttering his overwhelming lust in one final cry of pleasure, he exploded in his lovers welcoming mouth.

Greedily drinking all the creamy fluid, Grissom lifted his head and smiled at him. "Sweeter than sugar."

Still breathing deeply, Greg felt his heart filling up with burning joy.

Soaked by the smell and taste of desire, Grissom stripped off his shorts. Aware of Greg´s look at his erected cock, he teased: "Like what you see." Passionate lust burnt in his eyes.

Greg had never believed he would ever see him like this. Still horny, he just nodded.

Now fully naked, Grissom hugged him dearly, kissing him hard. At the same time, he started to caress Greg´s ass. "Mmh, what smooth skin."

Greg shuddered. Quickly, the heat in his body was rising again.

"Do you know where Grissom is?" Catherine was asking Nick at the lab at the same time.

"He got a call from the sheriff´s office and went there, half an hour ago."

Looking puzzled, Catherine wanted to know: "Well, and where is our new enthusiastic CSI trainee?"

"Along with Grissom."

"Is he? I´m a little surprised. Not long ago, Grissom avoided his presence completely. Now, he even took him with to the sheriff´s office. What for?"

"Why do you ask me? Lately, Greg doesn´t tell me anything, anymore. I even suspect he hides some secret."

"Really? What did you ask him?"

"What´s on his mind? What´s going on? Is he seeing anyone? Why do Grissom lately act so different around him?"

"And what did he say?"

"Not much. So out of his usual character. I even think something happened at the Crime Scene today. They had an argument or something else."

"Mmh?" Catherine was thinking. She remembered the time, when Greg had almost lost it. She had asked Grissom to talk to him. He had done it. Afterwards, Greg was his old self again. Until now, she never wanted to know, what Grissom had told Greg. Now, she wondered. It must have been something.

Same time, another place.

Grissom whispered: "I want to fuck you."

"Please, do it. I want it. Badly. For such a long time." Startled, he bit on his lips, because of what had escaped him.

But Grissom left the subject alone. He kept stroking Greg´s ass. Taking it further, by sliding one finger in its tight opening. Greg tensed a little and Grissom stopped, waiting for his lover to relax. Feeling Greg´s muscles to ease, he went in deeper.

Greg complaint impatiently: "Don´t. Take me. Now."

Grissom felt his last drop of doubt melting away. "What a naughty boy you are. No patience at all." He removed his finger and spun Greg on his belly.

Without a word, Greg got on his hands and knees, waiting for him to take him.

At this sight, Grissom found his heart filled with so much affection, it scared him. He hesitated, but Greg´s yearning "Please" let him finally forget all his concerns. Quickly now, he moved Greg´s legs a little apart and slid into him.

A shiver run through the young man´s body, he whimpered softly.

"Am I hurting you?"

"No."

Grissom began to move. First at a slow pace, he didn´t want to hurt his young lover.

"Oh, this is good."

Greg´s encouraging words made him increase the rhythm, pushing in deeper. Lustful groaning was his reward. Soon the hotness and tightness of Greg´s hole took all his control. Like in a fever, he was plunging madly into Greg. Not being aware of anything else, anymore. Not even the man, whom he was claiming. The lust in his groin became almost painful.

Greg didn´t bother. "Yes. Yes. Fuck me. Fuck me more."

His demanding and covetous begging made Grissom even hornier. A loud groan escaped his mouth. Enforcing his brisk, harsh strokes to the limit, he was now nearly ravishing Greg. His young lover was shaking and whimpering in pure delight, Grissom could feel he was close to come again. That feeling of power, dominating him, making him come, was giving him such a stroke of pure pleasure, it made him come so fast and hard, he feared he would have a blackout. Uttering one wounded cry, he exploded in Greg´s devoted body, spilling all his liquid into him, collapsing on his back.

Being buried under him, hit by his own climax, Greg stifled his lustful screams, by crying into the mattress. For a minute, Grissom lay still, snuggling to Greg´s back, who enjoyed this peaceful closeness silently. It made him almost happier, as the wild sex before. Sadly, it didn´t last long.

Quickly, Grissom got to his feet. In a conventional, almost insulting tone he said: "Take a shower and get dressed. We have to go back to the lab."

"What´s wrong?"

"Nothing. But we are almost gone for an hour. They'll ask questions."

With mixed feelings, but not complaining, Greg went to the bathroom. Devoted, as always.

Ten minutes later, they were sitting in the car, driving back to the lab. Absolute silence ruled. There was nothing to say. At the lab, Greg opened quickly the door of the car, but Grissom hold him back by grabbing his wrist. "Listen. We had a good time."

Greg blinked.

"A great time," Grissom corrected himself. "But we are not together from now on or something like that. Do you understand?"

Even so, Greg felt tears stung behind his eyes, he stayed calm. "Sure, Grissom. You´re the boss." Before Grissom could respond, Greg left the car and was almost running into the lab.

Grissom wasn´t feeling as relieved about Greg´s surprisingly chilly reply, as he thought he would be. For a moment, he felt the urge to follow Greg, to take his words back. But in the end, the moment passed, and he didn´t.

Greg, still running, bumped into Nick.

"Hey, watch it. Who you are running away from? Grissom or the sheriff?"

Greg didn´t smile a bit about his joke. "Very funny."

"Well, what did the sheriff say to you?"

"Say?"

"He said something, didn´t he?"

"Just the usual. I need a suspect. I need the case solved. As fast as possible."

Greg is using Grissom´s exact words, Nick thought amused. The teacher´s pet.

Michael came by, stopped and observed him intently. He started smiling. "Well, well, well, my dear Greggo, how is my favorite buddy feeling today?"

Greg opened his mouth to give him a proper response, matching Michael´s in his bold tone. He closed it immediately, when Grissom joined the little group.

"Well Nick, what´s new?"

"Not much. Hodges is still analyzing the cigarette butts and the unknown substance. Brass and I will question the suspect in ten minutes."

While Grissom was talking to Nick, Michael was switching his interest to Grissom, watching him closely. His amused grin widened.

Seeing this, Greg became nervous. What´s he grinning about?

Nick´s next question for Grissom made him even more nervous. "And? What did the sheriff say to you?"

"Just the usual. I need a suspect. I need the case solved. As fast as possible."

Nick repressed a laugh. "Really?"

Greg´s face was burning with embarrassment.

Luckily, Grissom didn´t notice Nick´s amusement. Maybe, he only played, he didn´t. "Yes. Let´s go to my office, Nick. I need to know all, you found out about the suspect."

After they had left, Greg addressed the still present Michael. "What are you smiling about?"

"Did you take a shower?"

Greg winced. "Sure. Before I went to work."

"I meant, quite recently."

"No. Of course not."

"I think, you did. I think, our big boss did too."

"You're crazy."

"Am I? We were having a little fun, weren't we?"

"I really don´t know, what you're talking about."

"Alright. It´s none of my business. All I have to say is this. Be careful." He started to turn away, but couldn´t refuse to ask one more question. "Was it worth it?"

"Michael!"
