Sara heard the door to the women's restroom creak open. Silently, she hoped whoever it was would take care of business quickly and move on. 'Dammit' she thought as she could hear Catherine talking on her cell phone to Lindsey. Why couldn't she just go outside, or into one of the labs, or hell the broom closet would have even worked for a little privacy. She should know.

Sara had to bite her lip to not make a sound as a pair of hands grazed her hips. She leaned her forehead into Nick's well muscled chest and silently begged him to stop. Catherine just kept talking. Sara stood there in the oversized stall at the far side of the bathroom trying to keep her erratic breathing silent. Her blouse was completely unbuttoned and her pants were unzipped and barely clinging to her hips. Catherine finally ended her call. Nick's hands continued their search for bare flesh and Sara couldn't help but gasp for a moment as Nick fingers slipped under the back of her panties. She bit her lip and clung to Nick as his hands cupped her buttocks.

Sara heard Catherine's voice, "Who's in here?"

Sara knew she'd better answer. In a voice that was more of a croak she replied, "It's me, Catherine."

Concern was etched in Catherine's voice, "Are you ok, Sara? You sound kind of funny."

Sara didn't dare look up at Nick, who was surely grinning, "I don't feel very good, I just have cramps. I'll be fine. I may be a while though."

"Ok. Let me know if you need anything." Catherine offered, sounding motherly.

"I will. Thanks." Sara replied, hoping that Catherine would just leave.

Fortunately, Catherine left the restroom. She had only gone in there for a little privacy for her phone call.

Nick let out a chuckle and whispered in her ear, "You feel good to me, Sara."

Sara finally looked up at him, "That was close and you know it." She was right, he was grinning. She couldn't help but smile back at him.

"Yeah, but it was fun." Nick leaned down and kissed her neck. His hands gripped her butt more tightly as he picked her up and pushed her against the wall of the bathroom.

"Do you know what you do to me?" Sara breathed in a husky whisper, wrapping her legs around him.

"Do you know what you do to me?" Nick whispered in reply, his lips making an assault on her neck.

Sara murmured as she pressed herself against him, "I have an idea." His arousal was evident.

Nick let out a groan. He pushed her harder into the wall and captured her lips with his. Their tongues made a frenzied assault on each other. Finally, the need for air drove them apart.

Panting, Sara, breathed in Nick's ear, "We need to get back to work before Catherine comes in to check on me." Her legs loosened their hold on him.

Reluctantly, they stepped away from each other. Sara button up her blouse and pulled her pants back up to their proper level before zipping them up. Nick pulled his shirt back on over his head. It had ended up on the toilet paper dispenser in their frenzy earlier. Sara reached up and helped smooth his hair out. He grinned as he reached over and combed his fingers through hers. Sara grinned as she noticed lipstick on the edge of his mouth. She reached up and rubbed it off. Nick kissed her hand as she did. She grabbed his hand and exited the stall. As they made their way to the door, Sara motioned for Nick to stay put until she could make sure the coast was clear. Silently, they both exited the restroom and walked off in different directions.
