A/N : I hope you like this chapter :) R&R? Thanks!

"No no." Calleigh blushed. "No offense Mac. But look, all the victims are indeed single. And like you Mac, they're practically married to their jobs and do not socialize much. The first vic is a lawyer, the second vic, Rodger Williams, is a high school teacher and look, now the third vic, he's an accountant. They practically lived in their offices, just like you."

"So this killer is really targeting guys like me. But there must be a place where she met those guys. Maybe a cafeteria, or a diner." Mac suggested.

"You're right. They must have crossed paths somewhere."

"So, Mac, you really have no idea who might want to do this? Probably a female who was obsessed with you?"

Mac was really thinking hard. He couldn't think of anyone that would do this. The last was Ella Mcbride. But that was long ago and he doesn't think that she would do such things. He was really stuck. He has helped too many people to notice them.

"Mac. Don't think too hard. You're getting old." Mac raised his brows at Jo, giving his annoyed expression. "We'll get this killer, Mac. I'm sure she'll slip and make a mistake or maybe we'll find something soon." Jo reassured him.

After conferencing with the New York Crime Lab, Horatio excused himself to get coffee for all of them while Calleigh had gone back to her lab. Mac and Jo decided to follow Horatio to the pantry to get some rest after the tiring morning, cracking their brains on the case. When Horatio gave them the coffee, he was gone in a split second.

"Wow. He's slick." Jo and Mac laughed and stole a kiss from Mac when suddenly they heard a commotion in the lab. CSI instincts kicked in and they went to see what had happened when they saw Horatio and Calleigh so tensed.

"Well you're slick too." Mac smirked.

"I'm so sorry Cal. I shouldn't have left you." Horatio said, eyes on the floor, hands fiddling with his sunglasses.

"Sorry? That's all you can say?" Calleigh blared, her fists balled up in anger. "You left me Horatio! You left just like that! Without an explanation!" Calleigh continued. Tears was already swelling in her eyes.

"See Mac.. I told you something was going on didn't I?" Jo rolled her eyes this time, and still continued listening to the arguments.

"I didn't mean to Cal. I know I'm at fault. I shouldn't have started this. I know I've crossed the line far too much and I know I can't turn back." Horatio said softly.

"Hell you're damn right! You crossed it too far Horatio Caine! You were the one who initiated it and you left! How could you do that to me! I want an explanation!" Tears was already rolling down her cheeks.

"I was afraid Cal. I'm your boss. I just couldn't cross that. I know Calleigh. That was stupid of me." Horatio still couldn't look into her eyes.

"You only care about other people don't you? I should have known. I've worked with you for so long. I really should have known and not let you in at all." Calleigh said, already sobbing hard.

"I was afraid that once we go there, we would regret it Cal. I won't regret it but I don't want you to regret it. I don't want just one night. I want forever Calleigh. I want forever." Horatio replied and Calleigh looked up at him immediately and was already sobbing.

Horatio tried to calm her down by taking her into her arms but she resisted and kept pushing him away. Horatio didn't back down and kept trying to calm her down which she finally did calm down and sobbing in his chest. They were in their own world, shutting the rest of the world away from them. "I'm not going to regret it Horatio. I want it."

"I'm sorry Cal. I'm sorry. I'm not going to run away again. I promise." Horatio whispered through her hair. Calleigh looked up at him, "You promise?" she asked. "I promise, but we'll take it slow alright?" Horatio assured her and she nodded, knowing that they did went too fast the night before. He took her lips in his, reassuring her once again. They had started to deepen their kiss when reality hit them that they're in the lab. They parted and laughed to themselves.

Horatio walked out of her lab, and it hit him that Mac and Jo was still in the pantry. Jo and Mac quickly went back to the couch when they saw Horatio walking towards the pantry. They pretended as if they didn't see anything or hear anything. They had acted casually in front of Horatio. In fact, they were pretending to have a conversation when Horatio walked in.

"So Mac, I think you might need the rest. Why don't I send you to your hotel? Or if you haven't booked them yet, I have guest rooms available at my place."

Both Jo and Mac turned and smiled. "Oh no it's okay. Adam has helped us book our hotel. So you don't have to trouble yourself. And besides, we can cab there." Mac replied.

"Oh. That's a shame. But at least let me drive you there and we can have dinner together since we didn't have a proper lunch. Taxi won't be necessary." Horatio smiled at that.

"Alright then." They smiled.

In the car, Mac and Jo felt better. The atmosphere was so much lighter. There was no tension like before. They were all smiling. Calleigh was no longer just staring out of the window. She looked more cheery and brighter. Jo elbowed Mac and gave him a smile and mouthed "I-told-you-so". Mac tried to ignore her and look out of the window when he felt a hand crawling up his lap. He quickly turned and smacked Jo's hand away from his lap. "Stop it Jo." He growled which made Jo smirk.

"Wow. This is a nice restaurant. Must be expensive." Jo commented.

"Don't worry about it. Some people owe me a favor." Horatio chuckled.

"Ahhhh...Taking advantage I see." Jo joked, making them laugh.

The four of them went in together and were guided to a table. Mac sat side by side with Jo while Horatio, with Calleigh. As they waited for the food to arrive, they did lots of catching up. Mac had told them about the recent incident regarding the Messers being held hostage and how they had handled it. They even updated Horatio about Stella who had already left the lab. Suddenly Mac felt something up his leg. He realized it was Jo. She was definitely up to something. Mac gave Jo a death stare. Jo seemed to ignore his stare and continued the assault on him. She slid her hand up along his thigh and up to his crotch. Mac gasped and blushed.

"You okay Mac?" Horatio asked when he saw Mac gasp.

"What? Yeah. I'm okay." Mac was totally embarrassed at what just happened.

Mac pushed her hand aside and gave her a glare. "Stop it Jo. We're in public." Mac growled. Jo didn't care. She still continued the assault on him. Her hand was already at his groin, fondling him. She realized that Mac was getting aroused by it. She could feel him hardening in her hand. She chuckled. Mac's face was already flushed red.

"Mac, you sure you're okay? You're getting 'redder' if that's even a word." Horatio asked again.

"Yeah yeah. I'm fine. Oh here the food comes! God I'm so hungry!" He was never as happy as before. He was so glad the food came fast enough to stop Jo from assaulting him. Once again, he glared at Jo and smirked, teasing and giving her the "hah-you-gotta-stop-it-already" face.

All the food arrived almost at the same time. Horatio winked at Calleigh. They were all so famished. That was apparent by the way they finished the food within minutes. It was excusable though, since they didn't have their lunch. After finishing their food, they stayed for a moment to do a little bit more catching up before heading home to rest for the day. Horatio had sent Mac and Jo to the hotel they've booked. Horatio, being the gentleman, accompanied them to the lobby, helping Jo with her luggage while Mac carried his own.

"Hi. I'm here on a reservation. I think Adam Ross made the reservation earlier today." Mac enquired with the receptionist at the lobby.

"Your name Sir?"

"Mac Taylor"

"Alright. Hold on a moment..." The receptionist looked over his desktop to check for the reservation. "Okay. Here we go. Mac Taylor. Reservation for one." He continued.

All eyes went huge. They were caught by surprise. "Hold on. What did you say? Reservation for one? It's supposed to be for two. I think there was a mistake." Mac said.

"No Sir. The man who made the reservation clearly requested for one bedroom. And unfortunately, there's no more rooms available." Mac had growled at that. He didn't expect Adam to do that. Mac and Jo looked at each other.

"Well...I think we got to just share a room." Jo suggested and smiled at Mac.

"I've got a spare room if you want." Horatio offered Mac. Mac looked at Jo and denied the offer. "It's okay Horatio. We'll be fine. We'll adjust to it. Besides I think it would be 2 single bed. So, no worries." Mac turned down the offer politely.

Horatio sent them up to the room, helping them with the bags. Upon entering the room, they realized that it was a king-sized bed. Not two single beds. Horatio chuckled at that.

"My offer still stands you know." Horatio offered again.

"It's okay. I'll just sleep on the couch."

"Alright if you insist. I'll pick you up tomorrow morning. Let's hope there'll be no more victims tomorrow. You two have a goodnight and a good rest."

"Alright. See you tomorrow." He smiled, knowing that Horatio still didn't know about them.

Mac and Jo went into the room while Horatio and Calleigh made their way home. They've got unsettled business to deal with tonight. Meanwhile, in the room, Mac and Jo had settled down and was already preparing for bed. They were totally exhausted from the whole day of trying to catch the killer.

"Jo, that was too much okay. Too much." Mac said.

"What was?" Jo asked back cheekily.

"Don't you dare pull that on me again. I almost lost it alright."

"I know. I was just teasing you." Jo chuckled and went over to Mac who was watching television on the couch.

Jo started teasing him, sliding her hands up from his thigh to his crotch once again. "Jo, I'm watching the news." Mac growled. Jo went to switch off the television and continued with him. Slowly, Jo got up and sat on his lap, kissing him and rocking on him. Her hands reaching up, unbuttoning his shirt and caressing his bare chest as she leans forward placing a soft kisses to his sculpted neck bone. She could already feel his hardening member between her legs. Mac had lifted her top and began sucking on her breasts hungrily. He couldn't control himself. Jo had already tested him enough earlier during dinner.

Quickly and carefully, Mac lifted her and brought her to the bed. He was never the kind of man who would make love to a woman on a couch. Mac was now in control. He wants to make Jo suffer for what she did to him earlier. Slowly, Mac reached down to her panty, tugging at it a little bit and slides it off her feet. He began teasing her back, inserting his finger slowly into her wet velvety fold. Jo couldn't help it but to part her thighs slightly as she arches towards him. Everytime she is about to lose control, Mac slowly slips his finger out of her, leaving her so frustrated. Gasping softly she feels him parting her legs to torture her again. Jo couldn't take it anymore. She arched her hips towards him again as she moans softly whilst her bright brown eyes silently begging him to take her. Mac couldn't stand her begging.

Mac allowed her to undo his pants, freeing his hardening member and slowly, he slides the large head of his member into the silken depths of her wet velvety folds. As he slowly thrusts into her, she grips the sheets beneath her and her body near shivering with pleasure as yet another orgasm rocks her body and goose bumps rise over her flesh. And as she feels him grip her soft creamy flesh she feels herself join him in climax, his heat filling her as she clenches around him tightly. Panting softly she whispers "wow" as he rolls over to hold her and she starts to relax. Laying her head against the strength of his chest she closes her eyes lost in the moment.

"I see why Adam only booked a room for us." Jo commented and they both laughed at that. "You think Horatio and Calleigh is gonna be busy like us?" Jo continued.

"Jo…That's their personal business. Not ours. Come on. Let's head to sleep alright. We have an early morning tomorrow. I don't want to give a bad impression." Mac said in a serious tone.

"You think they know?" Jo asked as her made circles on Mac's bare chest.

"Who?"

"The team. Who else."

"They're trained CSIs. I wouldn't be surprised if they knew." Mac laughed.

Horatio and Calleigh on the other hand, had gone home separately after strolling on the beach, savoring every moment together. They've reconciled and agreed that they would take it slow and easy. Horatio wanted more than just one night stand. He wanted something special and magical. He wanted forever. So does Calleigh. They both wanted forever. That night, Horatio got a callout.

"Caine." Horatio answered groggily.
