Since their encounter in his office a few months ago, Greg had made it his mission to get his revenge on her. His job being what it was, it was easy for him for find out when the pathology lab was distinctly quieter than usual and gave him his moment of opportunity.

It was only a 10 minute drive from The Yard to St Barts and Greg had never been so grateful for it, any longer and he either would have lost his nerve or potentially exploded. He pulled up in the staff car park, adjusted himself and put his best proper D.I. face on. He made his way through the corridors of the hospital and straight to the lab where Molly worked. As he reached the door to the lab, he took a deep breath before pushing the door open.
"Greg! Hi! I didn't expect to see you here today!" she said smiling and making her way towards him
"Dr Hooper, may I speak to you in your office please?" he asked her formally, walking towards the small office in the corner of the lab.
"Greg? What is it? What's wrong?" she sounded nervous as she followed him to her office. He said nothing as he faced her "Greg, what's happened? Please tell me".
"Dr Hooper, I'm here to place you under arrest"
"What?! Under arrest? On what charge? What's going on?"
"You have the right to remain silent…" he started to reel off the statement that he'd said thousands of times before, but never in this kind of situation. He put his hand on her shoulder and turned her to face her desk.
"This is enough Greg! I demand to know what is going on!"
"You are in no place to make demands" he growled back at her, "and as for the charges, well, you are being charged with indecent exposure and public indecency"
"What?!" Molly exclaimed
"We have hard evidence against you, and I plan to see that you are punished for it" Greg replied, moving closer to her, pushing himself against her back, allowing her to feel his already straining erection.
"Oh! I see!" All of a sudden it clicked what was happening, he was getting his revenge after her little trip to his office. "I'm sorry detective, I just couldn't help myself" she said meekly.
"You will be sorry Dr" he walked forward, pushing her against her desk while running his fingertips down her spine.
"Is there anything I can do to get off of this charge detective? I'm sure we can come to some sort of arrangement."
"And what do you propose?"
"Well, I'm under arrest for indecent exposure, maybe a repeat offence may convince you to show some leniency"
"Tut tut, trying to bribe a police officer, seems you really are a naughty girl that needs to be punished."
She shivered at his words while his hand came to rest on her ass before giving it a quick slap. She exhaled sharply as his hand met her skirt covered rear but held her position against the table.
"I think it's time you learned how to behave in public Dr Hooper" he stepped back from her as he continued to speak "place your hands on the desk Dr Hooper."
She did as asked and placed her hands on the desk in front of her
"Now, bend over."
She followed his instructions, bending at the waist and pushing her ass back towards where he stood.
"Good girl" he growled, stepping towards her to run his hand down her curved back and once again slapping her ass. She couldn't help but let a small moan escape her lips, encouraging him to repeat his previous action. He walked towards her and placed one of his feet between hers, "spread them" he ordered.
Molly slid her feet apart, allowing him to stand between them pushing his erection against her.
"Oh my detective! What a large weapon you have there! Are you licensed to carry a concealed weapon, or do we need to get it out in the open?"
"None of your cheek Dr, I'm the one in charge here."
As he pushed himself against her once again, he brought his hands onto her hips before running them up her sides and round on to her breasts, filling his hands with them and squeezing.
"Mmmmm, Inspector Lestrade!"
While one hand continued to play with her tits, the other moved back to her hip before running down her leg and back up to undo the buttons on the front of her shirt and pulling it open. He pulled the shirt from her shoulders before sliding his hand down her uncovered back to the zip of her skirt, pulling it down and letting her skirt pool around her feet.
"Lift your feet" he ordered. She obeyed, lifting one foot then the other while he moved her skirt out of the way with his own foot.
"Turn around."
She turned to face him for the first time since he started their little game, and smiled at him.
"Is this what you want detective? Me at your mercy being punished for being such a naughty girl?"
He said nothing put took her face in his hands, pulling her in for a hard kiss, moaning into her mouth. As they broke apart he lifted her up and carried her across the room, sitting her on the edge of her desk in just her underwear before kissing her again. As he pulled away he ran his eyes over her in a manner that could only be described as predatory.
"Such a naughty young thing, I'm going have to teach you how we behave in proper company"
He kissed her harshly again before running his tongue from the hollow of her throat and up the side of her neck, enticing a sultry moan from her lips. He continued his ministrations with his tongue, working back down her neck and throat and across her shoulder before coming to rest at the top of her tits. Without looking up, his mouth still covering her in hot kisses, he reached round to unhook her bra before sliding the straps down her arms and pulling it off her body. He took only a moment to take in the picture of her in just her knickers reclining on her desk before taking one of her already taught nipples in his mouth, teasing it with his tongue and sucking it hard. While his mouth alternated between her aching nipples, his hand was stroking down her side and across her hip bone and thigh, tantalisingly close to the edge of her underwear. He placed one hand on her shoulder, gently but forcefully pushing her back against her desk leaving her with her legs dangling over the edge. He gave her nipple one last suck before starting to kiss his way down her stomach and over the tops of her thighs. He could hear the gasps and moans coming from her, but ignored them and continued with his plan. He ran one hand up from her ankle to her thigh before teasingly running one finger across her knickers.
"Mmmmm, such a naughty girl getting so wet while under arrest, it's just not proper. I'm going to have to take these away from you" he teased while running his fingers up and down her increasingly wet knickers. He lifted her hips before slowly pulling her knickers down her legs. He brought them up to his face to inhale her scent before dropping them on the floor and standing back to admire her naked body. He wanted to make her wait, tease her but he just couldn't hold himself back and went straight for her wet pussy, running a finger up and down her slit before slipping 2 inside of her. He started slowly, gently pushing his fingers into her before pulling them out just as slowly, stretching her. As he moved his fingers quicker, pumping them in and out of her while ghosting kisses up and down the inside of her thigh. He could feel her tense under him, trying to hold back the inevitable but he wanted her to let go and he knew exactly what would work. He pulled his fingers out of her and set about sliding his tongue across her, slipping the end of it inside of her before flicking it over her clit. He felt her hands gripping onto his shoulders through his shirt, he was pretty sure she'd leave marks but it was definitely worth it, seeing her completely at his mercy. It only took a few more long licks and teasing flicks before he felt her fall over the edge moaning his name.
"Oh god! Greg! That was amazing"
"Thats Detective Inspector to you Dr Hooper, and I'm not through with you yet"
"Is that so Detective? Are you going to hold me for further questioning? Pump me for information?"
"None of your lip girl"
He pulled her from her position on the edge of the desk and spun her round so she was facing it
"Come on detective, time to get that truncheon of yours out"
He growled into the back of her neck before bending her over the desk and unzipping his fly, releasing his hard cock that had been dying to get out since he arrived at her office.
"Time to teach you that lesson I think girl" and before she could reply his cock was buried deep inside of her. He knew they both liked it when he took her from behind, but this was something new. He couldn't control himself, having her like this, and neither did he want to.
Molly groaned as he slid into her, feeling his hard cock deep inside of her, stretching her open. She knew he would't be gentle, but that wasn't what she wanted. She wanted, and needed him, to take her and fuck her. He pulled nearly his full length out of her before slamming back in. He knew what they both wanted and went about it, pounding in and out of her, groaning into her neck while his hands gripped onto her hips. Molly wanted to speak, wanted to scream, but nothing would come out apart from heated moans. She felt his hands grip tighter on her hips and she knew he was close. She took one of his hands and slid it round her body, down over her stomach and to her clit, guiding his fingers to where she needed them. Two more thrusts from Greg and she was falling apart and dragging him with her, her walls contracting around him and bringing him to the edge before he exploded inside of her. He continued to pump into her and play with her clit as they both came together bent over her desk.
"Christ Greg, that was.."
"I know babe"
"I'm not actually sure my brain's working anymore, I think you may have short circuited me"
"So you enjoyed my little bit of revenge then?"
"God, so much, I've always imagined what it would be like for you to bend me over at work"
All Greg could do was give her a crooked smile before leaning in for a tender kiss.
She let out a gentle moan as he pulled away from her "mmm, love you."
"Love you too."
"Oh, and Greg, next time you feel like playing the dirty copper, bring your handcuffs."
