The trouble with Angels

"You know, I really should..." Catherine attempted to stand up but Lorna pulled her back down onto the bed.

"Lindsey's with your mom, you don't need to go to work, your cell phone is off." She listed, crawling up the strawberry blonde's body. "You don't need to do anything." She kissed her lips, a grin spreading across her face. "Except this." Cath responded with a nervous smile of her own. Lorna continued to grind against her, letting her fingers toy with the buttons on Cath's blouse. She peppered kisses down her chest, popping the buttons open slowly – teasingly – one by one. When her shirt finally fell open Catherine jumped, roughly pushing Lorna off of her.

"Sorry, I just ..."

"Cath." Lorna sighed, sitting up on her knees. "What's going on? Do you not want this?"

"Of course I do." Catherine defended, holding her shirt closed with one hand and running the other through her hair. "I do. I just...this is all new for me. I just need more time." She realised too late what she had just revealed. Lorna's eyes widened.

"You've ... you've never..?"

"No." Cath mumbled, sitting more upright. "I'm sorry, I probably should have told you sooner. I just didn't know how to bring it up."

"No, no it's alright." Lorna said softly, a soft frown etched onto her face. "I just wasn't expecting it that's all."

"I'm sorry." Catherine mumbled, suddenly feeling very exposed. "I just need a bit more time to get my head around all of this. I hope you don't mind?"

"Alright." Lorna conceded softly. "Just don't make me wait forever." She added with a cheeky smile, stealing a quick kiss.

"Hey Cath," Nick greeted with a warm grin.

"Hey Nicky." She responded, planting a false smile on her face. "Did you enjoy your day off?"

She didn't hear his answer, too distracted by the arrival of Sara. The brunette had slipped in quietly, nodding in greeting to them. Nick was still talking, animatedly chatting about his weekend, oblivious to the fact that no one was listening.

"That's great." Catherine agreed, having not heard a word. She sidled around the bench to lean casually beside the younger woman. "Hey Sara, something you want to tell us?"

"What?" She asked, puzzled. Catherine smirked, tracing a mark on her neck.

"Had a good night have we?" Nick chuckled, joining in when he caught on. Sara slammed her hand over the hickey, her cheeks tinting bright pink. She pursed her lips, trying to hide a smile.

"No comment." She mumbled. Catherine and Nick exchanged amused giggles.

"Oh come on, spill. Who's the lucky guy?" Cath poked her playfully in the ribs.

"Uh huh." Sara shook her head. "Last time I told you guys about my love life you left a severed finger on my table." She joked, sliding out from between them. Cath laughed, shaking her head.

"Nice try." She called out after the departing brunette. "I'll find out somehow." Once she was out of sight, Catherine and Nick's gazes met as a shared idea planted itself in their minds and they both chimed:

"Greg."

"Hey Greggo." Nick greeted sweetly, ambling into the DNA lab.

"Hey." Greg replied, sending him a suspicious look. "What do you want?"

"Nothing." Nick tried and failed to look innocent. "I just wanted to say hi, you know, before shift."

"And…?" Greg pressed, going back to his computer. Nick glided over, leaning beside him.

"And…I was wondering what you knew about Sara's date last night." Greg stopped what he was doing, casting a sly glance at the Texan.

"What do you know about Sara's date?" He queried, narrowing his dark eyes. Nick shrugged.

"Nothing. That's why I came to you." To his surprise the usually impish lab rat turned sober.

"In that case it's none of your business." He snapped his attention back to his work, doing his best to ignore the confused looks he was receiving from his friend.

"You do know something don't you?" He asked.

"Sara likes to keep her private life private. I think we should respect that." Greg answered enigmatically, effectively ending the conversation. Nick shook his head in bemusement.

"Well?" Cath asked, not looking up as she poured two cups of coffee.

"He wouldn't crack. But he definitely knows something." Nick frowned, reaching for one of the mugs. He scowled when Cath moved it out of reach.

"Ah. It's not for you." As she spoke Sara wandered in and Cath immediately materialised at her side, offering her the steaming mug with a bright smile. Sara stared at it for a moment before tentatively accepting.

"Thank you." She said. "I'm still not telling you."

"So … this mystery guy. Anyone we know?" Catherine smoothly slipped into conversation as they photographed the scene.

"Greg wouldn't give in, huh?" Sara guessed correctly. Cath sent her a bashful smile.

"You know we're only teasing." She offered light-heartedly. "Although, it wouldn't hurt you to be a little more open you know." She added with a sly sideways glance. Sara shrugged.

"I have my reasons." She mumbled softly. Cath stopped what she was doing, fixing her young colleague with a curious gaze. "I trust you guys, but there are some things that you just don't need your colleagues knowing about you. You know?" Catherine's features softened.

"Yeah. I know." She whispered.

"Oh God." Cath groaned as Lorna's hands crept underneath her shirt, teasingly stroking the skin beneath her bra. She could feel hot breath on her skin.

Lorna's soft hands moved around her back, her fingertips barely brushing the clasp of the bra before Catherine stilled her movements.

"No." She whispered.

"Come on Catherine," Lorna whispered, changing their positions slightly on the couch. "Just relax."

"Lorna..." Cath began but the other woman cut her off with a soft kiss.

"We can take it slowly, just relax." She moved her lips to her neck. "Trust me Catherine." The way she spoke her name, husky and low, sent a tingle down the blonde's spine.

"Lorna, please." She begged, attempting to wriggle out from underneath her.

"What?" Lorna asked, still not stopping her ministrations.

"Please, I want you to stop." Cath said as forcefully as she could, her hands gripping the redhead's waist. Lorna finally stopped what she was doing and looked into Catherine's watery blue eyes.

"What's wrong?" She asked.

"I don't know." Catherine admitted sadly. "I just can't do this."

"How do you know if you haven't tried?" Lorna contradicted. Cath met her gaze, deathly serious.

"Please." She begged again. "Just give me some more time." She could feel emerald green eyes reading her face for a long minute before she heard a soft sigh.

"Alright." Lorna agreed, climbing off her. "Look, I've got to go."

"You don't have to." Cath interjected, leaping to her feet after the other woman.

"It's okay. I get it." Lorna held up her hands. She offered what she hoped was a understanding smile, but the disappointment in her voice was hard to disguise. "I'll call you in the morning." She kissed Catherine's cheek and slipped out, leaving the blonde alone. As the door clicked closed, she dropped despondently onto the couch.
