Summary: Lines began to blur as their bodies moved in tandem. Wrong became right and lust became love just as nothing outside the two of them existed any longer. That was until Nick felt it, that little gold band on Warrick's left hand.

He wasn't sure how it happened. One minute he and Warrick were screaming at each other in his living room. And the next . . . well that found him pinned up against the wall with Warrick's lips crushing against his. All the air was forced out his lungs, but he didn't mind. No he didn't mind at all, especially when Warrick's hands tugged his polo out of his jeans, skimming over the heated skin beneath.

He wasn't sure what had prompt the argument, but knowing his moods lately, it was something trivial. But at the moment he couldn't find it in himself to care, not when his shirt was pulled over his head and Warrick's warm, wet lips were traveling down his neck. It felt so good, like he was on fire, but he didn't have the breath in his lungs to vocalize it. He struggled for a moment, pulling his arms free and giving Warrick a gentle shove. It was just enough to break the connection of Warrick's lips to his skin, enough for him to be able to draw in a breath.

Warrick's body was still flush up against his, but he could feel the tense muscles and the straining erection pushing into his hip. He knew Warrick wanted this as badly as he did, but the look of guilt that flooded into those green eyes was like a knife to his gut. But the regret he heard in Warrick's voice was even worse. "Ah, shit Nick. I'm sorry- I wasn't thinking-"

Nick cut him off, shaking his head. He grabbed a fistful of Warrick's shirt and pulled him closer, until their faces were only inches apart. He opened his lips to speak, but no words came forth. Instead, he brought his eyes up and stared intently at those green eyes watching his every movement. And in those few seconds he tried to convey everything unspoken, his love, his anger, his acceptance, his need, but mostly, his want. His want for this to go further.

Then slowly, he pressed his lips to Warrick's again, this time with his hands free to roam; one dipping underneath the shirt to splay against sizzling flesh, and the other grounding itself on Warrick's neck, keeping the man as close as possible. Their lips moved in harmony to each other, Nick's parting to allow Warrick's questing tongue entrance. Nick slid his left leg up against Warrick's, hooking it around his hips so their groins were aligned, delighting in the moan he tore from both their throats.

Some where in the mix of denim grinding against denim, and tongue against tongue, they made their way to Nick's bedroom. Nick gasped as he was pushed back onto the mattress, Warrick not far behind him. His fingers made quick work to the buttons on Warrick's shirt, relishing in their victory by running up and down the muscular chest and over the rippling abs. But Nick's fingers were far behind in the race as Warrick was now tugging down his jeans, smirking at Nick before he eased the boxers down as well. That was the last thing he was aware of before those lips circled around his cock and sucked him deep.

Nick's hips bucked off the bed, his fingers tightening in Warrick's hair as he tried to go deeper. Warrick smiled and hummed around the cock, enjoying the incoherent moans he was able to pull from Nick's throat. Nick's head was tossed back, the cords of his neck straining out and begging for attention, his eyes closed and his lips parted and swollen, trying to drag in just a little more air. Nick's abs contracted as he moved, trying to increase the delicious friction around his cock, the muscles of his legs pulled taut as he fought for control.

Warrick kept one hand on Nick's hips, his tongue continuing its slow and pleasurable torture, and his other hand freed him of his jeans. Once he was free, he pulled his lips off Nick long enough to move the man farther up the bed. Nick blinked hard and groaned at the loss, but his lips cracked into a smile as he saw Warrick holding a condom and lube. He grabbed the condom out of Warrick's hands and slowly rolled it down over Warrick's cock, adding a little more pressure than need be just to draw out that hiss of pleasure.

Then his legs were wrapped around Warrick's hips drawing him down, inviting him in. When it looked like he was about to protest, Nick shook his head. "No, Rick. Now. Please now." Then he was filled. With one quick thrust Warrick sheathed himself completely until he and Nick were flush together. Nick groaned and tensed for a moment before he started to rock his hips, begging Warrick to move.

Lines began to blur as their bodies moved in tandem. Wrong became right and lust became love just as nothing outside the two of them existed any longer. That was until Nick felt it, that little gold band on Warrick's left hand. It felt cold and accusing as it pressed into Nick's skin where Warrick was holding his hips tightly. He froze completely, his body going rigid, but it wasn't with pleasure. It only took a moment for Warrick to notice.

"Nicky?" his voice was raspy and the words were little more than panted out, but the look in his eyes said it all. Did I hurt you? But Nick couldn't move, couldn't think for a moment until Warrick brought his hand up to his cheek, the light from the hallway glinting off the gold ring for only a moment as the hand moved. Then there it was again, pressing against his cheek, mocking him, hissing words at him in the still silent room. ‘Adulterer'.

He slammed his eyes shut, praying that when he opened them that it would all just be a dream, that the man laying on top of him, inside of him, wouldn't be there, or that that damn little band of gold would just disappear. But when he opened them again, all he saw was pure concern and love dripping from the emeralds above him. And when he pressed his eyes closed again, it was to hold back the sudden tears. Tonight he was going to be selfish. Married or not, he wanted Warrick, and he wanted him just like he had him. He couldn't dwell on right or wrong, wouldn't think of the consequences sure to come, didn't want to think of how long he'd desired to have Rick look at him the way he was right now. No. Tonight he wasn't gonna give a damn about anyone but himself.

With a stronger force than he thought, Nick rolled over, taking Warrick with him until he was on top of the other man, straddling his hips, bodies still connected. He opened his eyes and grinned down at Warrick, though he knew the tears were still visible. He leaned down and gently brushed his lips over Warrick's, barely any pressure but enough to let him know everything was all right.

Gathering his legs underneath him, Nick rose up and dropped back down, groaning as Warrick's cock filled him again, hitting that sweet spot buried deep. He rose again, but when Warrick's hands came up to grasp his hips, he caught them in mid-air. He shook his head before pinning them above Warrick's head, burying them beneath the pillows. He wasn't going to let it guilt-trip him again. Out of sight, out of mind.

Warrick's hips came up to meet him then, and he let go, moaning loudly, his face upturned towards the ceiling. He got lost in the rhythm, in the pleasure, in the throaty moans and gasps, in Warrick's eyes gazing up at him with that look. And he held that gaze as he rode Warrick, feeling the tension building, ever growing because neither wanted to let go just yet. But in the end it was Nick who would let go first, loosening his grip on Warrick's right hand to gain the needed friction on his cock. All it took was two pulls of Warrick's hand across his flesh and he was done, tumbling over the edge blindly, with Warrick not far behind him.

When he opened his eyes again, he was lying on Warrick's chest, Warrick's arms wrapped around his waist, fingers drumming to the rhythm of the heartbeat pounding in his ear. He picked his head up and smirked at the dazed and sated look on Warrick's face, then slowly pulled the man out of him and slid off to the side. He sat there for a moment before he felt the bed shift. His heart sunk. Looking over his shoulder, he watched as Warrick stood up and pulled on his jeans, using a discarded towel to clean himself.

He didn't turn back around until he was buttoning his shirt. Nick just sat there in shock, eyes full of hurt and disappointment that was quickly masked. He quickly pulled the sheet around his waist, no longer comfortable being quite so exposed in front of the man. He leaned back against the headboard and feigned relaxation as Warrick sauntered over.

"I should go. Tina will be wondering where I am." Warrick stood there awkwardly for a moment, torn between staying and leaving when it was obvious what needed to be done.

Nick swallowed, trying to form words but in the end just nodded. He opened his eyes briefly when he heard the rustle of clothing growing fainter and watched as Warrick walked out of his room. And he sat there listening as the door was closed and locked. Listened as Warrick's truck was started and took off down the road. Sat there for twenty more minutes to assure himself that Warrick was really gone before he collapsed sideways onto his pillow, burying his face in it and letting those forbidden tears fall.
