The office computer tech.
"Dave, why are you in my locked office?"
"I was running some computer updates after everyone left so as not to interfere with their work. I sent out an email about it earlier this week."
"I guess I missed that email."
Dave surveyed the situation. "Nice pool. So you're a mermaid?"
"At least part time, yes." Cleo swam over to the side of the pool closest to the door, folding her arms on the edge. "What do you intend to do about that discovery?"
"I could, uh, leave and we could pretend none of this ever happened, if that's what you want."
"You're not going to threaten to blackmail me about this?"
"No, ma'am. I work with computers all the time and I've been with this company for a decade. If I was the kind of person to cheat this company I would have done it long ago. I'm not that kind of person."
Cleo thought back. Dave had always been a good employee and never once caused trouble in the office. He was quiet but polite, never complained, never bothered her for a raise. She had no reason to think him anything but trustworthy. Something about the way he'd phrased his response made her curious though.
"You'll pretend this never happened if that's what I want. What if it was up to you?"
"To be completely honest, Cleo?"
"Yes."
"I'd like to have sex with you."
For a moment, Cleo was speechless. "Excuse me?"
Dave shrugged. "You asked me to be honest."
"I'm your boss!"
"Which is why I wouldn't have said anything about it otherwise. But you're only a few years older than me."
It was true. From what she knew of Dave he wasn't the kind of person with the competitiveness and ambition to run a company or even an office. He was good at his job and that was enough for him. Cleo looked him over. The bulge in his pants revealed he wasn't joking. He was decent looking - not someone who got the attention of the ladies, but no slob or pocket-protector-wearing computer nerd either. Cleo had been single since she first became a mermaid, unwilling to risk being exposed, not even with a one night stand.
"Is this just because I'm a mermaid? Some kind of fetish?"
"Cleo, you're a smart, attractive woman. If you weren't my boss I would have asked you on a date years ago. Having sex with a mermaid would certainly be a bonus though. But if you say no then I'll leave and never mention this again."
Cleo thought in silence for a moment then pushed off from the wall with her tail floating across the water, her pert breasts glistening with water droplets and giving Dave quite the view. She resumed her place against the wall of the pool farthest from the door, all the while mulling over what to do next. Dave never took his eyes off her.
Oh what the hell, Cleo thought. "Get in here, but never mention this to anyone, ever."
Dave nodded, made sure the door was locked behind him, and stripped his clothes off as he made his way to the water. Cleo got a brief look at his erect member before he waded into, striding vigorously over to her. They considered each at close range, looking each other in the eyes for signs of doubt and not finding any. Dave straddled Cleo's tail and slowly leaned in to give her a light kiss her on the lips. Then Cleo wrapped her arms around Dave and pulled him in to a deeper kiss. The two slowly explored each other's mouths, tentatively at first but with growing passion.
Dave's hands explored Cleo's body, finally settling on her breasts which he caressed. Cleo moaned involuntarily, so long had it been since someone touched her that way. She reached under the water, sizing Dave up then guiding him into her. Her body shuddered. Cleo had pleasured herself, but never as a mermaid. Given how sensitive she was finding herself it something she now regretted. Dave began to thrust and Cleo curled her tail up behind him, gently pushing him deeper and helping to establish a rhythm. Her back was to the wall of the pool as Dave drove himself into her. She could feel herself building to an orgasm when Dave suddenly erupted into her which finished her off as well. They both kept going until completely spent. Dave slumped into the water next to Cleo.
