Watching the detective Part 1

Maura Isles birthday had come very early this year. That was the thought that went through her mind, one of the very few coherent thoughts that her mind could form, as a very dextrous tongue worked her clit in tiny circles, occasionally interspersed with being sucked into a warm mouth, while two long, strong fingers worked their way in and out of her sopping pussy.

Maura's hands clenched hard in another spasm, one in the sheets of her bed, the other in the dark, curly hair of the woman driving her towards an absolutely shattering orgasm. Somewhat sadly she mourned the fact that she would be so wrecked that she would be unable to return the favour, at least not for a little while.

They had been working towards this moment for a while. Maura's friendship with Jane had become the one constant in her life, the rock she clung to as the shifting currents of her life battered away at her and with Jane it was safe, comfortable.

The trouble was, Maura didn't want safe and the comfort she sought was not what she had built up with Jane, it was the comfort of a lover not a friend she craved. Tentative steps had been taken, discussions had deepened, flirting had grown stronger until the pressure had become almost too much to bear.

The result had led to where they both wanted, a night of passionate, wondering exploration, as they both found out how much pleasure they could give each other, how much each could take.

Maura had found, much to her surprise, that once Jane's initial shyness had been overcome, which had taken about an hour once Maura set her mind to it, the detective was willing to do just about anything Maura suggested.

Jane on the other hand had been surprised at just how uninhibited and frankly kinky the prim and proper Medical Examiner became when it came to sex. Maura was just about up for anything, which meant both of them had stretched their boundaries a lot since they became lovers.

All of which had led them here, to Maura's bedroom, the air filled with softy groaning, panting, the slapping sounds of skin on skin, low moans and snatches of words.

Maura's voice grew louder as she was driven closer and closer to ecstasy, groans turning to moans, turning to cries and finally a scream as the fingers inside her curled into the one spot she craved to be touched, while a warm mouth sucked her clit inside where sharp white teeth nipped and teased.

"Oh god yes, YES, YES!"

Maura's scream filled the room, her climax driving coherent thoughts out of her head as she thrashed on the bed, held in place by strong arms on her hips and thighs. Finally, she went limp, as she felt fingers slide out of her, her pussy walls clutching at them in a futile attempt to keep them there for just a little longer. Groaning at the loss, she looked up into dark eyes that were staring at her, taking in her post-orgasmic pleasure, taking pride in a job well done.

She locked eyes with the detective, letting her know how much she appreciated her work, when the eyes suddenly squeezed shut in ecstasy and a low, moaning sound was forced from Riley's mouth.

Raising her eyes up, Maura looked into Jane's eyes, almost black with lust, as she drove her strap-on into Riley from behind, a lustful smirk on her face as she pistoned the toy's nine inches into Riley harder and faster than ever.

As Maura watched, Jane slid her index finger into her mouth, moistening it with saliva, before moving it out of sight behind Riley. A second later a surprised shriek filled the room, Maura smirking as she knew exactly where Jane had put it; both Jane and Maura had come to enjoy ass play, something Detective Cooper was just learning.

Now it was Riley hanging on to Maura and filling the room with screams and moans as Jane drover her higher and higher, before leaning forward, reaching around with her other hand to toy with Riley's clit, dragging a screaming climax from her victim, before the pair of them collapsed as Riley's limbs gave out.

A few minutes passed as the three of them lay there panting, slowly recovering, before Riley spoke.

"Give me a minute, and I'll return the favour Jane" Jane just chuckled softly.

"No way, it's Maura's turn next; she's been looking forward to fucking your ass ever since you started flirting with her"

"Hey, I didn't know there was anything more than a close friendship between you two, otherwise I wouldn't have even gone there" Maura looked over at where Riley and Jane lay, long lean limbs still tangled together.

"Oh, there's no need to apologise, look where you ended up" There were soft smiles all round at that.

"Yeah, well, when you invited me over for dinner, I didn't realise I was on the menu"

"The pleasure was all ours Riley" Riley smirked knowingly.

"Oh no it wasn't, not all yours I can assure you" Jane slowly moved her hips, drawing the toy out of Riley, causing Riley to squeeze her eyes shut in combined pleasure and loss. Finally it was out and she was able to form coherent sentences again.

"So what next?" Jane chuckled.

"You mean right now, or next weekend" Maura smiled, she knew what Jane was referring to. Riley looked confused

"Next weekend?"

"We were thinking of inviting Suzie Chang over for dinner next weekend, perhaps you'd like to join us. I think you'll enjoy what's on the menu?" A slow smile crossed Riley's face, she'd had her eye on Suzie since she'd joined Homicide and Jane had introduced them.

"Count me in"
