Olivia's POV

Both of my hands were caught in one of his, his strong grip holding me tightly even though I'm squirming at Matt's ministrations. His other hand was trapping the increasingly loud noises from escaping from my mouth; stopping me from alerting the whole station from what we were doing in the showers. I can feel Kelly's hard cock pressed against my back as I squirm. Kelly has a talent with his mouth between my thighs and has a liking of proving he can turn me into a weeping mess begging for release from his mouth only but Matt is just as talented with his fingers. The steady thrusts of 2 fingers in and out of my pussy, the quick clockwise motion of his thumb on my clit and the occasional pinch of pain as he twists my nipple to try to warn me to keep quiet is keeping me on the edge of release. Kelly whispers dirty fantasies into my ear isn't helping me follow their orders of not cumming without permission. I'm trying focus my gaze on Matt yet every time I manage it Matt hits my G-spot with such accuracy that my vision blurs and instead I train my gaze on the shower wall behind him.

"Maybe we should leave this desperate… hmm sweetheart, not let ya cum till we get home. Don't think we would do that… what do you think Matt, should we leave her?"

A pained whine escapes Kelly's hand over my mouth at his suggestion. It's another 4 hours of shift left before we could go home and I'd be sure they wouldn't just let me do them hours in peace either. Suddenly my world is moving and I'm being shoved to my knees. A surge of pain flicks through my knees as they hit the floor of the shower but my hands are free and I'm eye level with Matt and Kelly's rock hard cocks. I feel a hand tangle in my hair stopping me from moving forward and a small whine escapes as I try to move to lick the small bead of precome that is on the tip of Kelly's cock. The hand in my hair stops me and the bead drops to the floor and is washed down the drain. I'm aching for the feel of one of their cocks in my mouth, the heavy weight of it on my tongue, the salty taste of pre-cum, the muffled curse as I deep-throat him. I lick my lips and employ my only tactic that I have at my disposal currently. I look up though my lashes and do my best pleading expression at Kelly. He's more of a soft touch than Casey and he breaks quickly,

"Fuck! Matt… look at her" He runs a thumb over my lips and I put it in and begin to suck at it, running my tongue run over the calluses on the bottom of his thumb.

"Damn, you want cock, sweetheart? Yeah, I bet you do. Look at ya, wishing that was mine, such a little cock slut" I feel Matt gives way to Kelly's dirty talk as the hand in my hair slackens. Kelly's thumb retracts from my lips and he lets his hand fall with a sigh to his cock.

"Go on sweetheart, suck Matt's cock, show him what a good cockslut you are" Kelly keeps talk as I move forward and engulf Matt's cock.

Kelly's POV

Olivia is emitting small whimpers of pleasure in her sleep as she moves slightly under the sheets in the spare room bed. The tear tracks have now been rubbed away, yet her eyes are still red-rimmed from crying. My gut is still wrapped in knots and churning from the scene I walked in on 30 minutes ago. Matt had almost been zombie like, Olivia a sobbing wreck over his knees. I turned away from the bedroom and saw my boots lying haphazardly on the hall floor- I move to tidy them however; my mind isn't really on task as it moves back to Matt. It had been the hysterical sobbing that had alerted me to the disaster ahead of me as I had headed for the main bedroom of the house. It had caused me to break out into a half jog. We didn't start punishment without everyone present- it was one of the rules we had set down. We also usually stopped punishment when Liv started to cry- something wasn't right.

I had pushed the door of the bedroom open to find Liv over Matt's knees, his hand a steady thud on to her butt. Yet, little things unsettled me from this image- Liv and Matt were still in the clothes they had come home from the station in a good hour before. Considering this wasn't out of the ordinary, I kept looking. Then my eyes spotted the belt. It was lying next to Matt's feet on the floor- this may have been normal for some but it was a red flag- Matt was a stickler for being tidy so the belt hadn't been there this morning when we had left for shift this morning. I moved, Matt didn't even stir from his rhythm and I could see the deathlike grip he had on Liv's hips as I skirted around him. It's then that I saw her butt- it was redder than the fire truck of 81 and there was the purple bruising welts from the belt across her butt. Yet Matt seemed unseeing- and clearly unhearing as I tried to talk to him-

"Matt… CASEY!" yet even at the use of his last name he didn't respond, didn't look up. That was when I moved, grabbing Matt's hand and stopping it from falling again- he tried to fight me then, pushing against my hand yet I had the upper hand. I pulled Liv to her feet, her legs buckled and she nearly toppled to the ground. I quickly swing an arm under her collapsing knees and, letting go of Matt's hand, brought the other around her back. I lift her bridal style up into my arms and she buried her head into my neck with a small sob, her arms locking themselves tightly around my neck like she's afraid Matt will tear her away from me. Yet Matt was unmoving still as I moved Liv out of the bedroom and down the hall to the spare room. There I placed her gently on the bed, trying to avoid her butt, yet even as the quilt cover brushes it she yelped in pain. I wrap my arms around her and gently pull her into my arms. She buries her head into my chest and I hold her tightly. It had taken 20 minutes to calm her down from sobbing to hiccups and finally shaking that had eventually given way to sleep 10 minutes ago. It was then that I had retreated to the door of the bedroom.

Now standing in the hallway, I turned my thoughts back to the present and to my other lover. Moving away from the hallway, I move to the kitchen and then towards the main bedroom in search of Matt. The flat's small enough to find him quickly. He doesn't look like he is fairing better with the situation than me or Liv is. He's sitting on the couch in the living room staring unseeingly at his hands. The sounds of footsteps on the floor make him start with a jump. He watches me with wary eyes as I move to sit next to him with a sigh. I run my hands through my hair and over my eyes in despair. I have no idea where to start this conversation- Matt was the one with all the information on the BDSM scene, the one that knew what we were doing. I was following his lead so far, now I have to take the lead on a road I have no idea how to drive on.

Olivia's POV

Matt's cock isn't as thick as Kelly's yet it's longer. Uncut and still thicker than the average, he fills my mouth with practised ease; I let my tongue run over the slit causing his hips to jerk and a muffled curse to be emitted from above me. I trace the vein down the underside of his cock and steadily relax my throat to allow his dick to slip into my throat. I contract my throat muscles and feel his cock jerk inside my throat. His hand tightens on my hair and I let him take over as he begins to thrust in and out of my mouth. All I have to do is kneel, keep my teeth out of the way and relax my throat to prevent from gagging. It would be almost soothing to let Matt take control yet Kelly makes his presence known by bringing the ache of my arousal forward to the front of my mind. Kelly is stroking himself, I can hear it in his voice, it's slightly lower, deeper pitched as he continues his talking.

"Look at you. Kneeling like a good girl at his feet… God, I can see the outline of his cock in your throat… such a good cock slut sweetheart… bet she's tight… warm around you Matt… That's it, he's close… you gonna swallow him sweetheart… look at ya, bet ya need to cum… bet ya aching real bad for it. That pussy is dripping wet, can see that from here… ain't gonna fuck ya though. Gonna leave that for tonight… fuck… let ya wait all day for it…"

I feel Matt's thrusts become more erratic, faster, less controlled as Kelly's words and my throat begin to affect him. He's close now, and as I double my efforts to make him cum, he suddenly buries himself deep in my throat. A rush of salty cum that is so far down my throat that I don't really have a chance to taste it. His hand releases my hair and he moves backwards to slump against the shower wall. His chest is heaving, his eyes still open and watching though. I look up and find Kelly's eyes, he's held off cumming and is stroking himself at such a slow pace it must be painful. He's shuddering slightly and leaning on the wall beside Matt for support. I move to him, bat his hand out of the way, and gently move to bring one of his swollen balls in to my mouth. His hand moves to my hair and he tugs hard-

"Don't tease sweetheart!" His voice sounds wrecked, on the edge of desperation.

"OLIVIA!" Matt's stern tone sends a shiver down my spine and I move my mouth away from Kelly's balls and , taking his cock in my hand, cover the tip of his cock with my mouth. I twirl my tongue around the tip, dipping in to the slit. I then move my mouth further down to deep throat Kelly. I begin to move slowly and I feel let out a guttural sigh. His cock makes my jaw ache at the sheer circumference of it and I feel Kelly suddenly start cumming in sudden spurts down my throat. Just as Kelly's hand distangles itself from my hair, I feel a hand on my back and a warm body cover my back. Matt's hand moves around me and with a flick of his thumb against my clit, he whispers

"Cum for us… now!"

The slight sensation and his dominating tone is enough to chuck my idling arousal over and as I feel the ripples of pleasure heighten, I awake.

Kelly's POV

"What the hell happened? I was gone for half an hour. We were fine when we left the station, how did this get so bad, so quickly Matt?" My voice seemed to echo in the quiet flat even though I'm speaking quietly. Unable to stand still, I began to pace. It takes Matt a while to answer, his voice is cracking with emotion and barely audible.

"I just kept remembering Darden. God, watching Andy consumed in flames. Jesus, Kelly that could have been her! If that house had had vents, she wouldn't have lived. I just, kept thinking she could have got killed…"

It's then Matt breaks off with a small sob, I move to him and pull him into a hug. I got it. I shouldn't but we both remember Andy. The instinct to try and protect Liv had been hard for both of us to overcome at the best of times, to remember that Olivia can protect herself. Yet today, going into that townhouse before I had cleared it to be safe had been more than stupid- it had been life-threatening. Matt had overreacted. He had crossed a line and trust had been broken yet I kind of understood. She hadn't deserved the intensity of the spanking by a long shot but I got Casey's mindset. I just didn't know how to we were going to proceed from here.

"God, Kelly, what have I done?" Casey is staring at his hands with a pained look on his face. I go to take Casey's hands to try to let him know I understand but he yanks his hands away.

" Don't. You don't have to pretend to still want to be with me…"

I try to derail this thought immediately going to cut him off-

" STOP! You made a mistake we can work past that Matt…"

"Liv won't want to be with me anymore, I won't break this relationship apart…"

"MATT. Your part of this relationship. We both want you…."

"You don't know that! You both can't trust me anymore. I can't trust me anymore…"

Matt has risen in the argument and is now moving out in to the hallway ,grabbing his hoodie and boots. He won't look at me and is avoiding my desperate touches to try to make him stay.

"Casey… Please, we need you. Don't leave… Don't leave me," I'm desperately imploring him to stay yet he turns and grabs his keys.

"I need some air. To think this through…" is the last words from Casey's mouth as he walks out the front door and the door slams shut.
