Chapter 4

Nick was leaning against the arm of his sofa. Greg was curled into him with his head on Nick's chest, snoring softly. A week had passed, since the incident with the acid, and the two men had become nearly inseparable outside of work. During work, Nick had begun to touch the younger man in nonthreatening ways. A pat on the shoulder here, a brush of his hand on Greg's arm there, even the smallest invasion of Greg's personal space.

After work, they would go out to breakfast, sitting in the booth long after they'd both finished eating. They chatted about interests and Nick's past, but Greg still wouldn't open up about his own past. Nick did find out the younger man had a love of video games, comedy movies, and Rocky Road ice cream. They would stay at the diner until one or two of the waitresses would walk by, pointedly glaring at them several times to express their desire for the two men to leave.

For the first time, Nick had invited Greg over to his place, instead of going out to breakfast. Suggesting instead, that he fix them both something, and they could watch a movie. Greg had agreed, and now the movie, Adam Sandler's 50 First Dates was at an end. About half way through, Greg had cuddled into Nick with a sigh at the sappiness of the movie. A few minutes after that, the younger man had fallen asleep.

Loath to move and wake the obviously exhausted man, Nick used the remote to switch over to the satellite DVR and ESPN. He turned the volume down, then set the remote aside again, before settling his arm across Greg's shoulder. Greg shifted marginally, moving his face into the crook of Nick's neck, before settling again.

Nick had been mindlessly watching the football game for several minutes, when Greg let out a whimper of fear. It was quickly followed by, "Nein! Bitte! Nicht wieder!"

Shock settled over Nick, as he realized the words continuing to spill out of Greg's mouth, as a result of his tortured dream, were unmistakably German. The fact that Greg was talking in his sleep, in German, had Nick convinced that the accent the younger man had tried so hard to mask was indeed German, and that Greg was not the native English speaker he had seemed to be.

Pushing this revelation to the side for now, Nick concentrated on waking the younger man up. Touching Greg's cheek gently, Nick murmured, "Greg, wake up." When that didn't work, he tried a little louder, "G, baby! Wake up, you're having a nightmare."

This finally worked, for Greg sat up with a jerk. Nick let him go, not wanting to risk frightening him further, but Greg didn't move away. His hand remained on Nick's chest, where it had been earlier curled between them. Their eyes met, and Greg let out a small sound of relief.

"You okay?" Nick asked, raising his right hand to lightly brush his knuckles across Greg's cheek.

Not trusting himself to speak, Greg nodded. It was the same dream that he'd been having since his escape. There had been a change to it the last few days, though. Each time, Nick had appeared in it, pulling the guard off of him. Nick's absence in this dream had made it seem so much worse.

"I'm sorry I fell asleep," Greg said a bit sheepishly. He wondered if Nick had been awake the whole time, began to wonder if Nick's presence in his dreams was merely coincidence, or coincided with the older man's being asleep, as well.

"It's okay, G," Nick smiled at him reassuringly, running his knuckles across Greg's cheek again. "I enjoyed watching you sleep, least until the nightmare hit you."

Heat rushed up Greg's neck, into his cheeks. "You were watching me sleep?" He felt Nick's hand slide down to his shoulder, felt Nick's thumb brush over the juncture between his neck and shoulder, couldn't help but shiver in delight at the feel of Nick's hand on him. As he succumbed to the sensations Nick was evoking in him, Greg's mouth failed to take direction from his brain. "Have you dreamt of me, Nick?"

The shock on Nick's face was immediate, but he continued to gently stroke his thumb over the skin of Greg's neck. "How'd you know I've been dreaming of you, G?"

Resigning himself to having this discussion, hoping he could avoid revealing too much, if anything, Greg said, "Because I think we've been sharing a dream. Tell me about it, please!" Avoiding the older man's gaze, Greg leaned back into Nick, hiding his face in the crook of the older man's neck before sliding down a bit and resting his head on Nick's chest. He cradled his right hand between them again.

Allowing his hand to slide to Greg's back, Nick voiced what had continued to gnaw at him since the first night he'd had the dream, "What's the significance of the German soldier, G? Is he supposed to symbolize who hurt you?" Without even realizing it, Nick had given Greg the explanation he needed.

Greg didn't speak, just nodded against Nick's chest, his eyes tightly closed.

"The rest of the dream?" Nick asked softly, his hand trailed up Greg's back to the younger man's hair, where his fingers ran gently through the soft strands.

Moving his head into the hollow of Nick's throat, Greg huskily said, "A manifestation of what we both want," then began to lightly kiss the older man's neck.

Feeling the blood rush to his cock, as Greg kissed his way up to his chin, Nick carefully took the younger man by the upper arms, pulling him away so their gazes could meet. "Are you sure? I don't want to do anything that might hurt you, G."

Unable to help the blush that spread over his face, Greg said, "I wake up covered in my own cum, but still so hard it hurts. I need this! I need you!" Reaching up, Greg pulled one of Nick's hands from his arm, brought it down to his crotch, pressed it against his rock hard cock. "Bitte! Please!"

Breath hitching in his throat, as he finally had his hands on what he'd been dreaming and fantasizing about for days, Nick gently stroked over the bulge in Greg's jeans. Using his other hand to pull at Greg's arm, Nick managed to maneuver Greg onto his lap. Moving the hand from Greg's arm to the back of his neck, Nick brought the younger man's lips to his own.

Their first kiss was tentative, just the meeting of lips, then Greg sucked Nick's lower lip into his mouth, laving his tongue over it, and their kiss deepened. As their tongues met, Nick stroked Greg's cock, then set his hand over the bulge and squeezed gently.

Groaning, Greg rearranged his position, so he was straddling Nick's thighs. As he continued to kiss Nick, his hands trailed to the hem of Nick's shirt, pulling it up enough that he could run his palms up the older man's stomach and over his sides.

Nick moved his hand from Greg's crotch to his thigh, his other hand moving to Greg's other thigh. Rubbing the palms of his hands up Greg's thighs, Nick moved them to Greg's hips, then to Greg's ass. Kneading denim covered butt cheeks, Nick pulled Greg closer to him, so their cocks brushed together through their jeans.

His head falling back, Greg let out a low, "Oh, Gott!" Belatedly realizing that he'd spoken in German again, Greg tried to cover the slip, but what he said seemed to prove that his mouth had stopped taking direction from his brain, as he murmured, "You must be the reason I'm in this time."

Nick had been nibbling on Greg's neck, but now pulled back, meeting Greg's gaze with a raised eyebrow.

A fingertip trailed lightly over Nick's abs proved distraction enough, as the older man's skin seemed to dance under the touch, an involuntary laugh erupting from his kiss swollen lips.

Completely forgetting about what Greg had said, Nick captured the younger man's hand in his and brought it to his lips. Placing a soft kiss to each of Greg's fingertips, Nick murmured, "My bed would be much more comfortable."

Slipping from the couch to his feet, Greg captured Nick's other hand and pulled Nick to his feet. As Nick steered them in the direction of his room, Greg pulled Nick's arms around his waist, awkwardly pushing himself up against Nick as they moved. He managed to insinuate a hand between their closely pressed bodies, stroking it over the bulge in Nick's jeans.

Steps faltering slightly at the pleasure, Nick buried his face in the crook of Greg's neck. A moment later, a low growl of need escaping his throat, he reached for the hem of Greg's shirt, pulling it up over the younger man's head and tossing it to the floor. As they continued to move, nearly to the bedroom door now, Nick began to place light kisses over the smooth cream colored skin of Greg's shoulders.

Finally through the doorway, Nick brought Greg to a stop by pulling the younger man flush against him once more. His hands moved up from Greg's stomach to his chest, smoothing over lightly toned muscle up to the younger man's nipples. After teasing the tight little buds for a moment, he trailed his hands back down to the fly of Greg's jeans.

As Nick was pushing Greg's pants down his long legs, Greg twisted around to face him. Their lips met in another fiery kiss. And now it was Greg's turn to undress Nick. Starting with his shirt, he pulled it over the older man's head, allowing it to fall to the floor, already reaching for the fly of Nick's jeans.

Once his jeans were pooled at his feet, Nick gently pushed the younger man onto the bed, crawled up himself so that he was kneeling between Greg's thighs. Leaning down, he nuzzled Greg's neck, trailing kisses down to the clavicle, where he nipped the flesh and sucked it, before laving it with his tongue, ensuring there would be a nice mark there by later that night. As he continued to trail kisses on Greg's neck and chest, he fumbled the drawer to his bedside table opened and retrieved a wrapped condom and tube of lube.

Greg wasn't exactly sure what Nick had retrieved from the bedside table, but now Nick was working his way down Greg's chest, and Greg found he couldn't bring himself to care. Whatever it was, as long as Nick continued to make him feel this good, he would allow the older man to do just about anything to him. As Nick's warm tongue laved over his nipples, Greg arched off the bed, letting out a low keening whine. Nick's tongue dipping into his navel caused Greg to burst out in giggles.

Nick didn't stop, but looked up at him with an arched brow, chocolate colored eyes nearly black with lust.

Between giggles, Greg managed to get out, "No one's- no one's ever done that to me before." Of course, the truth was no one had ever done any of this to him before, as in his own time, it was inappropriate to have sex outside of wedlock, and he certainly wouldn't have been doing this with another man, during his own time. He had firmly decided that the times he'd been raped by the guard didn't count.

Greg was brought abruptly back from his thoughts by first a hand wrapping around his leaking cock, then a tentative tongue darting into the slit. He couldn't help the way his hips bucked, as his body insisted on more. Looking down, he encountered Nick's eyes, gazing intently at him, as the older man continued to lick and lav over his aching length.

A hesitant finger brushing across his opening had Greg bucking his hips again, a gasp of mingled shock and pleasure escaping him in a rush. This was so different from what had been done to him by the guard, that he nearly cried in relief.

"You okay?" Nick asked quietly, pulling off of Greg's cock just enough to murmur the words and wait for Greg's answer.

"Bitte stoppen Sie nicht!"

Greg didn't realize he'd slipped into German again until Nick said, "Fuck, G! I don't understand a word of German, but it sounds sexy as hell on your lips!"

And just like that, the fear of discovery was back. Pulling abruptly away from Nick, Greg tried to get off the bed, but Nick captured his wrist, stopping him. "Please, let me in. I want so badly to help you, take care of you, but I can't do that unless I know what happened."

Sinking back to the bed, Greg allowed his head to fall forward, eyes closing. He felt Nick release his hand, but didn't move to leave. He knew he could trust the older man, but could he take the chance that he'd be putting him in danger, or that Nick wouldn't believe him? "It's a long story," he hoped that alone might dissuade Nick, but it wasn't meant to be.

"I'll make time."

Twisting his head to look over at Nick, as the older man crossed his legs underneath himself, completely comfortable in his own skin, Greg said, "Either you won't believe me, or I'll be putting you into possible danger, or both."

Nick wanted to laugh, but sensed that the younger man wouldn't tell him anything if he did. "Greg, I carry a gun at work everyday. I think I can protect myself. As for the other, I've always considered myself to be open minded."

Breathing forcefully out, Greg then took a long deep breath, working out in his mind what he wanted to say. "I was born in nineteen twenty to David and Judith Sandler, in Germany." Sensing Nick was about to protest that there was no way this was possible, Greg said, "Please, let me tell you everything, Nick. I promise, it'll make more sense once you've heard everything. Then you can protest, or ask all the questions you want."

Greg's right hand settled over the tattoo on his left arm, his fingertip tracing over each number. "I graduated with a dual doctorate in chemistry and physics in nineteen thirty-nine, the year the war broke out. I was nineteen, and naive. I didn't think my family would be in danger. We were German citizens, after all. But then the soldiers began to round up German Jews who were citizens, too."

Thrusting his left arm out at Nick, tattooed side up, Greg said, "I was branded with this in Neuengamme, in 1940. I probably would have died there making bricks, but they found out about my dual doctorates. I was so naive at the time, I believed them when they told me that if I worked on their project, they'd let me go."

Scooting back some on the bed, Greg pulled his knees up to his chest and wrapped his arms around them before continuing, his eyes locked resolutely on his feet. "They already had their best and brightest working on it, but it was with my help that they finally made the breakthrough they'd been looking for."

Nick found himself transfixed by the younger man's story. He wasn't sure yet what to believe, but Greg was so sincere. When Greg didn't seem able to continue, Nick couldn't help asking, "What was it? What was the project?"

Finally looking up at Nick, brown eyes bright with desperation, but no madness, he said, "Time travel, Nicky."
