A/N: So a one-shot grew a second part, thanks to those who encouraged me! It's just as dark and adult as the first part if you need any warning.

Part Two

Brendan looked between us. I'd never seen the animal so wounded. Poor mite, this wasn't what he'd signed up for. Sharing? Brendan didn't know how. I wondered, in that moment, if things could get any worse for him. He'd seen for himself that Ste wasn't about to leave his safe little boyfriend and add to that, Brendan had watched precious, darling Steven succumb to me; he was pink and red and glistening because of me. Not only had Brendan watched him ask for it – from me – but he'd also been tortured by his own imagination. And I should know, when you've got a soul blacker than the devil, imagination is the greatest torture of all.

I hooked Ste around the waist with my arm and pulled him close to me until we were touching, bare at the hips. My fingers splayed on his thigh and my downward strokes made his lip-biting nerves dissipate for a moment: he was under my spell. I let his soft cock weigh under my fingers, knowing he wouldn't be shy for long. He even dared to look at me. He was learning.

"That wasn't the deal we made," Brendan said, knocking against my shoulders. Like a reflex Steven began calming him, laying his touch on Brendan's chest like I wasn't there. I tricked myself into believing he was protecting me from that brute, but really I knew better.

"Fine," I said, cocking my head to one side. "In that case, I'll see you out. Steven –" I caressed his jaw, "- make yourself comfortable."

"Brendan," Ste said, his lips full and slow. He licked them and I knew my bitterness lingered there. "It's okay."

He stepped back, mouth twisting. "You're okay with this? What, you want this?!"

I took the opportunity of their awkwardness to sandwich myself into the fractures of their affair. I manoeuvred myself behind Ste, wrapping my arms around his middle. Ste resisted, tensed up.

"Just give us a minute, will you?" he said, confidence bristling in his voice. He was the prize in this – the boy every one of us wanted. He stepped apart from me and I watched on coldly as he placed his hands on Brendan's arm, shaking his head. "This means we can be together tonight, don't it? If you leave, then I still have to stay."

Brendan could barely make eye contact with him. I knew his game, he was trying to stop himself piecing together the evidence of where I'd touched what was his. Ste had marks all over him; his hair ruffled, his lips red.

Ste's lips tried kissing the corner of Brendan's turned-away mouth, seducing him into the plan. He might've been trying to persuade Brendan in his own way but I knew he wanted more of me, whether Brendan was fooled or not. I stood and watched, resting against the wall as they grew entranced with each other, Brendan relenting into a full kiss. Seeing the two of them possess each other flooded blood to my dick. Brendan's hands dived into Ste's hair and I could just feel Ste's desire thrashing in his pulse as he opened his mouth against Brendan's, his tongue sliding between his lips. They were a sight: Ste's naked body, used and damp, grinding up against Brendan's suit, which creased in heavy folds when his erection pounded through. There was as much heat and fleshy groans in that one kiss than when his hole burned at my mercy.

But Ste surprised me. He blushed, panting and full of bleary energy, and stumbled a few steps back and away from the kiss, away from Brendan. I had expected him to start undressing the man he claimed to love, but – no – he looked towards me, casting his head back over his shoulder. It felt like he was in charge. Who was I to resist?

I approached, skulked towards him just as his daring slipped away, like he almost regretted it. He fell into the predictable habit of easing Brendan out of his clothes. But it was too late, I pressed myself up behind him, my cock hard and against him. Brendan looked dead inside as Ste's body bit back a gasp. He was probably still loose enough that I could fuck him without much persuasion or preparation. I pressed down on his shoulders, grinning in Brendan's presence – even if his gaze avoided mine – my cock rutting at the dewy flesh of Ste's arse.

I pretended Brendan wasn't there, concentrating all my efforts on Ste. I watched his hands shake and hesitate in the undressing of his lover. My hand closed around his cock, that blissful heat, and I lowered my mouth teasingly to his ear. "Hello…"

I wondered how much talking the pair of them did in bed, whether their affair was conducted mainly in grunts and curses, whether Ste's cum was a greater proof of his love rather than him verbalising, choosing to leave Doug. I wondered if for Brendan, having Ste share his soul was worse than sharing just his body.

My jaw pressed against the side of Ste's forehead. He was a mouthy little fucker at the best of times, but it was a whole other story when I had my thumb flicking against the head of his cock. He liked that – in jibberish moans – almost as much as when I rolled his balls in my palm. I quite fancied the idea of having him fuck me – just to really get under Brady's skin – but I too had certain boundaries when it came to sex and this arrangement.

Brendan watched us for a moment, his broad body now naked and slumped, wounded. I saw him take it all in: Ste's helpless, pathetic little mews, the way he jerked involuntarily to work a little friction between us, his arms submissively by his side, the leak of pre-cum that made my play faster to his tastes.

"No," Brendan said, backing away from us. Us. He tore around in his own torture, hands wrenching at his hair. "I can't do this!"

My eyes rolled, sighing as Ste stepped out of our embrace. How long was this charade going to continue? I rolled my thumb and fingers together – sticky.

"Brendan, if you want to go first, be my guest. We'll flip a coin for heads or tails." I poured myself a drink, shaking my head at Ste's grimace. "What did you expect Ste? That'd I'd sit in the corner twiddling my thumbs while he made love to you?" I mocked them in my voice, sucking at my fingers.

Brendan lunged at me and I could only smirk and the naked fool trapped in this situation where he could never win.

"I wanna have sex with Brendan," Ste said, saluting his chin at me with boldness. "And you can listen to this, right: I don't want you to touch me when me and him are together. After that…"

We were both hanging on his every word. I was waiting for it: I'm all yours.

"We can sort sommit, alright?" He shook his head like he was wrecked with it. Disappointment gnawed at me and when I relented it was only for a bargaining tool.

I studied them, a chair pulled beside the bed, my feet tucked under lotus-like. Brendan took a lot of persuasion but something snapped inside him like he was ready to prove a point. Ste had stopped telling him it was okay and that he loved him as Brendan's mouth possessed his, teeth roughly pulling at him.

Brendan savaged him with kisses as they hit the bed, Ste's body like a rag doll in his new determination. Ste would break, panting and tongue wet, for breath and I sat eager for him to meet my eyes but he didn't. A beautiful fearlessness consumed him and he let the threatening size of Brendan's dick friction across his flesh. He grasped at it with both hands, only for Brendan to pin them above his head, spreading his tongue across his throat, sucking viciously.

I wanted a part it in but they were so absorbed, so transfixed in each other I was shut out like a blackout curtain. It wasn't romantic – there wasn't the stillness and the time and intimacy for that – but it was a rhythm of perfect needs and desires being fulfilled. Brendan knew him exactly and Ste the same. It spread through me like ice, the knowledge I wasn't a part of this moment.

I savoured the sight of Brendan rising up onto his knees and spreading Ste apart. In the moment it took for Brendan to roll on a condom, Ste's face had fallen in my direction. It was a guilty accident and Brendan soon fixed his face back, lubricating him with saliva and plundering his fingers inside. Ste's head whipped away from me and he'd curled himself into a crushing position solely for Brendan's benefit. I wasn't getting off on them; I was biding my time.

The sounds Ste made weren't ones I recognised, weren't what he made when I'd fucked him, didn't even sound like they came from him. He was high and delirious on it, skin a rubbery pink with prints of white where Brendan commanded ownership of him. They bunched the sheets in sweat and saliva. Brendan machined his body like he was drunk on finally having possession, grappling as Ste's body shook in ripples.

There was love in it. Love in their open eyes and open mouths and breathy yearnings. A sick love. A sickness. Sick.

Brendan came and Ste's cock twitched, full with potential. He wasn't done.

I clapped my hands, launching myself at the bed. "Alright. Your turn's over." Ste bleated, feverish.

Brendan wasn't relenting so I picked up Ste's phone from the side, ready to dial Doug's number and as easy as that, Brendan withdrew, leaving Ste weak and flushed. I pulled him down the bed by his hips and wrapped my mouth around his cock.

Like I was an answer to his begging, Ste's fingers shot through my hair and I was pulled into the obsession of pleasing him, blocking out the way his eyes closed and the way Brendan moved to kiss him.

It was my mouth he came in. Mine.

Ste ended up between us on the bed. But like I thought, Brendan didn't share and I had to pull Ste on top of me to get his attention. He felt skinny and smooth and I wanted to paw and bury my mouth onto every inch of him. His nipples were glossy under my tongue, blood and arousal making them irresistibly stiff and his cock too, grew hard against me. We both made noises, skin thrumming.

The mood shifted when he initiated a kiss, one of his hands flat on Brendan's heart and the other hand steering mine to stroke the down of his backside. I felt him yearn for me, his mouth dragging on mine, his body lazily coiled. His moans came in little gurgling sounds, accidental and not obedient with the image that he was in love with Brendan. I slapped Ste's arse, riding our hips together.

Brendan sat up and pulled out of the bed and I groaned as the inevitable happened; Ste tore away from me and called out for Brendan, who had slammed himself into the bathroom. I looked on as Ste attempted to coax him out, knocking on the door and lying about feeling nothing for me. Lying.

The room was heavy with the scent of bodies and sex but I wasn't finished.

I shook my head at Ste, mouthing the words to the rhyme – liar, liar, pants on fire. His pout in full bloom and eyes dark.

"Come and show me a good time," I said, not a request.

His fingertips lingered on the bathroom door but his gaze hesitant. He looked towards the phone and I pretended not to notice.

"Steven…" I wanted my voice to lick him from the inside out. "You made a promise. And don't think you can kid around, we all know you want to." I made my way over to him, hunting him down. My mouth circled around his ear, flicking the lobe with my tongue. He jolted, my grip tight around his cock.

Brendan had opened the door in time to see his precious boy kissing my neck and thrusting into my palm. Ste was hot and needy, teeth scraping against my flesh.

I sucked in a breath as if I was apologising for Ste's latching onto me and pulled him towards the bed before Brendan could interrupt us. I'd never seen him without a smart remark or an undercoat of aggression. If I'd known how easy it would have been to wear him down I would have seduced Steven earlier, sent Brendan some home movies of me whipping his boy into shape.

Ste gazed at Brendan, chewing the lips he'd kissed me with. I gripped his wrist and once I'd shaken the menace, beckoned him on top, pushing his mole-flecked shoulders down until he got the message.

"You're a real mood killer, Brady," I said, soon satisfied as my dick met the back of Ste's throat. He gagged but with a little encouragement I had him continuing. The pathetic man stood by the bed watching on, gnarled in pain, wounded by each wet smack of Ste's lips around me. "Be a love," I said to Brendan, "Pass us a condom will you?"

I motioned him an air kiss and he moved towards the cabinet, also where my phone sat.

"If you think I'm stupid enough to keep one copy on that phone as blackmail then you're an idiot. So don't even think, don't even try."

I was struck by the force of Ste's mouth and pounded the bed with my fist, urging him to go slower. I wondered how Brendan felt being in love with such a slut – destroyed, by the looks of it. Ste complied perfectly with my every request.

Brendan appeared on the bed, by our feet and I was thrown, throat bobbing as I swallowed. He sunk three lubricated fingers inside Ste and like a light blinding a darkened room, I'd lost Ste to Brendan once again. He shuddered, mouth dropping me as he groaned and rocked back on the flex of his lover's fingers. I was tempted to scream, call the whole arrangement off, keep Ste locked in my bedroom for as long as I could fuck him, for as long as I could lock Brendan out of his mind. But keeping my cool, I swept my hair back and sat up in bed, gripping Ste's legs.

"Get away from him," I said to Brendan, our vicious exchange snarling across the body of the boy I had convinced myself we shared. "I'm going to enjoy this." I wasn't sure whether I meant having Ste ride himself on my dick, having control, or whether it was Brendan's loss I would enjoy the most.

They shared a kiss in front of me. They pressed foreheads, noses touching. I heard Ste murmur, only picking up the words: so much. The betrayal scorching through my blood only made me want to get my hands on him even more. I lusted after their pain.

I had a hold of his hips, poised so I could have him into how I wanted him. He wriggled across my lap, barely looking at me as he took a hold of my cock. It was business again.

I squeezed his thighs tightly. "Don't go all rent-boy on me, Steven."

"You wanna ride, I'm givin' you one, alright? Don't expect any small talk." He'd built up this armour of how he should be reacting, but now and again – a little nudge – and he'd be purring for either of us inside him. He might not have loved me, yet, but he came for me, he wanted me.

He let the devil enter him and now, blacker still, crueller, colder, rougher – I was inside him again. My hands on his body, his on mine, his speed dictating – my thrusts enslaved to his workings. His head writhed back, neck slender and choke-able. He clawed at my chest, whining and keening, the bed pummelling the walls. I liked to imagine the next room thought I was killing him. I was getting the same pleasure of having his cum shooting across my chest as I would have his blood.

Brendan intruded, licking the nape of Ste's neck, twisting his attention away. The little fuck smiled and kissed the brim of Brendan's moustache. I opened my eyes to see Brendan whisper in Ste's ear, bringing him to orgasm just with the tremble of his voice. Brendan controlled him. He mouthed what he'd be doing to Ste in my position. In my frustration, I scratched my nails across his back, making sure as I finished inside him, he'd have marks from me, still lingering.

Somehow exhaustion had him cuddled up to me. He enjoyed what came after danger. Brendan dressed and Ste indulged a curiosity by giving in to a long and intimate kiss with me. It was allowed when his ruler wasn't looking, I guessed. He stroked my hair, snatching his hand away when he thought he should.

"We're done here," Brendan said. "We're done."

"Were you always this much of a bore?" I said, looping my arm around Ste's middle and trying to keep a hold on him. "It was sex. Steven enjoyed himself. No harm done." I stroked Ste's cheek seconds before he left the bed.

"Let's get out of here," Ste said, placing himself into Brendan's arms. The scratch marks had already faded. "I need a shower." He grimaced, but then his voice softened, holding Brendan's face. "We're okay, aren't we?"

"You're not mine anyway, are you? It's not like you're coming home to me."

I laughed at the bitterness in Brendan's voice.

Ste shook his head, placing Brendan's hand on his chest. "I'm yours. Yours forever, no matter what else."

My eyes rolled. "Leave before I throw up."

"You're going to get rid of the evidence on Brendan? And the other stuff?" Ste said, pulling on his clothes that were hours cold.

"I won't be running to tell tales," I said. In the midst of his dressing, I stepped behind him and kissed his neck – a weak spot – he curled, like he had done time and time again. "For now."
