Emily had been watching JJ all day. From the seat at her desk she could see the blonde making her way to and from her office, flitting between her co-workers desks and the coffee machine in the break room. As subtly as she could Emily had been watching the blonde's ass, being sure never to stare to long or allow her friends to catch the looks. By the time the clock struck 3 pm Emily could no longer contain herself. She approached the blonde who was currently pouring herself yet another coffee. Keeping her voice low she leaned in, as if to grab herself a mug, and growled "Meet me in our bathroom. Right. NOW."
JJ smirked to herself as the brunette swivelled on her feet and quickly left the bullpen, she had been waiting all day for Emily to snap, she had made sure to bend over slightly more than was necessary knowing dark eyes were on her all day. She followed Emily after leaving an appropriate amount of time, so as to not raise any questions, after several twists and turns in the hallway she finally arrived at the small isolated bathroom in a rarely used section of the building. She and Emily had found it nearly a year ago and used it when they need privacy or a break from the perpetual profiling of the team, who were persistent despite their claims of 'respecting personal boundaries'. She knocked three times on the door to let Emily know it was her, and she was promptly let in.
Emily quickly and firmly re-locked the door after JJ had entered, only then did she turn her attention back to the other woman. Without a word she grabbed the blonde and pushed her roughly into the counter beside the sink. JJ gasped at the harsh movement and looked back at Emily through the mirror. Emily wasted no time, running her hands over the blondes ass, "Just what I thought." She said sensually, "You seem to be missing proper underwear Jennifer." She the took the top of the blondes skirt and pulled it down far enough to reveal the top of a white lacy G-string. Moaning at the stark contrast of the scant panties and her proper work attire, Emily pushed a finger under one string before letting it snap back down onto JJ's hip. "Why are you wearing this?" she asked, meeting the other woman's eyes in the mirror for the first time.
"I was out of clean underwear after our last couple of cases." JJ replied evenly. In fact she had been out of underwear, however, she had realised this conundrum yesterday and had plenty of time to do a load of laundry, she had simply wanted to push the brunette into enforcing one of her 'rules'.
"Ah, you can't lie to me you brat. I saw you check your drawers last night, you made the choice to tease me by wearing those. That's why I decided to wear this." She then pushed herself firmly into JJ's backside, allowing the blonde to feel what she had concealed underneath her dress pants.
"Oh my god! You're packing!" JJ practically squealed as she felt the hard length against her ass and thighs. The thought of Emily wearing a strap-on in the office all day sent a gush of wet and heat right to her core.
"Now you know the rule about these flimsy little things Jennifer." Emily said trying to control the amount of desire in her voice. "If I catch you wearing them I get to fuck you immediately, no matter what. Only I am adding another rule today, because you insisted on wearing this to work, you are not allowed to make a single noise while I fuck you. If you do I will stop immediately and I will not let you orgasm for a week." She said all of this with absolute authority whilst playing with the small amount of panty visible from the top of the askew skirt. "Do I make myself clear?" She again raised her eyes to meet the blue ones in the mirror. JJ nodded her assent, absolutely desperate to be railed and not willing to risk compromising that possibility by being any more of a brat today.
"Good girl." Emily said as she undid her thin leather work belt and pulled her pants open enough to free the dildo from the confines of the boyshorts that were holding it tight to her body. Once it was free she turned her attention to the clothing keeping her from her target, she grasped JJ's skirt from the hem and pulled it up around the blondes hips until the bottom of her ass was hanging out and Emily could access her core. She bent the blonde down further over the counter and ran one hand through her folds. "Already so wet for me." She purred at the feeling "Were you thinking of me all day? Thinking how I would own you in these little white panties, hmm?" The sight of JJ bent over and blushing at her words was getting to be too much for Emily. She quickly aligned herself with the blondes center, pulled the scrap of fabric aside and carefully rubbed the tip of her dick through the wet folds, gathering slick before pushing in just enough to stretch her tight entrance. Even the small movements made the dildo push back against Emily's clit and her growing arousal made each movement feel even better.
JJ tried to keep from making noise at the initial intrusion, the sudden stretching of her opening was always one of her favorite sensations, but she bit her lip firmly and dropped her chin to her chest in an effort to discourage any noise from escaping her throat. After a moment she felt Emily begin sliding slowly into her, pausing every inch or so to allow her to adjust for a moment. Even in her rough dominate mindset Emily always made sure to make JJ comfortable and not cause her any unintentional pain, a fact which made JJ love her even more. After the brunette had bottomed out and her hips sat flush with JJ's ass, she paused for a long stretch. Growing impatient the blonde pushed her ass back and rocked against the other woman's hips encouraging her to move.
"Oh impatient little thing aren't you?" Emily smirked. She quickly drew the dildo back before slamming it into the blonde, impressed that the other woman managed to not make a sound. She continued this rough and fast ministration, enjoying the feelings radiating up into her core and stimulating her deliciously. She could hear JJ's breathing picking up and watched as her knuckles whitened where she gripped the counter firmly for support. "Open your shirt. I want to see your tits bounce while I fuck you." The brunette demanded.
JJ began unbuttoning her blouse as Emily continued to pound into her, the change in angle as she straightened caused the dildo to hit her G-spot perfectly. As she was finishing the last button and opening the shirt fully, Emily let go of her hips to reach forward and rip down the cups of her bra, exposing her nipples. JJ drew in a sharp breath at the possessive and desperate act, thrilled with the sight of Emily's eyes fixed on her chest as it bounced in time to her movements. With the new visual stimuli Emily picked up her pace and used the blondes hips as leverage to pound into her forcefully.
Emily was nearing climax from both the movements of the base of the dick against her clit and the sight of JJ flushed and desperately trying to hold in the numerous noises she usually made during sex, especially rough sex. She knew by the pink tint of the blondes chest and the way her breath was getting ragged that she was close too. "Look me in the eyes Jennifer. I want you to watch me while I destroy you." Once she saw the blue eyes through the mirror she reached forward and found the blondes clit and began massaging it vigorously. Emily watched completely entranced as the blondes face began to contort with pleasure and her muscles clamped onto her dick making it harder to move in and out. JJ let out a strangled cry as she came, Emily couldn't even bring herself to care as she too climaxed. She continued to thrust into the blonde as they both rode out their orgasms together.
After she began to come down from her pleasure she stilled her movements before pulling out of the blonde slowly. She quickly turned and used paper towels to wipe down the length of the dildo, she would not be able to clean it properly until she returned home. After securing it back in her underwear and fastening her pants she turned back to the other woman.
JJ was just finishing buttoning her shirt after returning her now slightly wrinkled skirt to its correct position. She turned to face Emily once her appearance was more in order. Emily quickly captured the blondes lips in a passionate and dominate kiss, "When we get home I'm going to have to punish you for making noise." She promised with a teasing whisper. Then she turned on her heel and left the bathroom, leaving JJ to collect herself before returning to her desk as if nothing had happened.
