Charlie’s not just asleep, he’s completely passed out, in the deep sleep that only comes from too much whiskey. He looks so peaceful, all the tension gone from his body and the little furrow between his brows smoothed out. Mac reaches out, his fingers hovering over Charlie’s cheek. He touches him lightly, trailing his fingertips over Charlie’s cheek.
Charlie sighs and twitches in his sleep. His t-shirt has ridden up and Mac can see the soft curve of his belly, dusted lightly with dark hair. Mac’s gaze follows the trail of hair that leads from Charlie’s navel down into his boxers. He wants to touch him properly.
It’s a thought Mac’s had for a while now. It usually remains at the very back of his mind, like something lurking in the shadows, and only surfaces when he’s wasted. Like he is tonight.
Dennis is asleep behind him, his steady, even breaths in sharp contrast to Mac’s hurried ones. He’s warm, his arm pressed against Mac’s back. There isn’t much space in this bed, and when all three of them are sharing it’s hard to avoid touching each other. It’s not very often that they all sleep together; it’s only when they’re at Charlie’s place. Otherwise it’s Mac and Dennis in their own beds and they trade off sharing with Charlie when he’s not on the couch. But here the only option is to squeeze all three of them into Charlie’s sofa bed.
Sometimes Mac will take advantage of that. He’ll insist on going to Charlie’s, just because he loves being in between the two of them - especially on cold nights, like this one, when he’ll be sandwiched between them as their bodies seek out warmth. He takes a deep breath, but all it does is make him dizzy. He can smell Dennis and Charlie, a sort of aftershave and whiskey and sweat smell, strong and intensely male.
Mac carefully slips his hand into his sweatpants and takes hold of himself. He presses his lips tightly together; he can’t make a sound. Doing this is okay, but only if Charlie never finds out. Mac's gaze rests on Charlie's mouth. His lips are parted - inviting. They look so soft. Mac wishes he could kiss him. He could wake Charlie up with a gentle kiss - maybe he would open his eyes, his gaze softening as he sees Mac. He’d cup Mac’s cheek, whisper that he’s always felt the same as he leans in -
Mac shivers as he realises, suddenly, that Dennis is awake.
Mac isn’t sure how he knows, only that he’s very aware of Dennis’s gaze burning a hole in the back of his head, like a predator whose prey has just made a very stupid, life-threatening mistake.
“You're pathetic,” Dennis murmurs. His voice is clear, not sleepy like Mac expected, and Mac wonders exactly how deeply Dennis had actually been sleeping.
“Dennis-”
“Shh. You’ll wake Charlie.”
Mac hears the sheets rustle and he feels Dennis’s body press closer, the heat of him feeling almost scorching against Mac’s back.
“What would Charlie say?” Dennis tuts softly. “His best friend” - it’s said sarcastically, every word dripping with venom - “jerking off to him while he’s asleep.” Dennis keeps his voice low, a soft purr against Mac’s neck. “How do you think he’d feel?”
Mac whimpers. He realises, stupidly, that his hand is still in his pants. He goes to pull it out but Dennis reaches over and grabs his wrist.
“I didn’t say stop.”
It feels like the room has dropped by ten degrees. Dennis’s nails bite into Mac’s wrist.
“Dennis, we can’t-”
“ We can’t? It looks like you’re the one who started this, baby boy. I’m just making sure you finish it.” Dennis lets go of Mac’s wrist and grips his erection through his pants. “Do I have to do everything myself?”
“No,” Mac breathes. His hand shakes as he slips it back into his pants and wraps it around his dick.
“Good boy.” Dennis moves his hand to Mac's hip.
Mac keeps his eyes on Charlie as he starts to stroke himself.
“Tell me what you want.”
“I… I don’t know.”
“Sure you do. You were lying there looking at Charlie with your hand around your dick. What were you thinking about?”
“I wanna kiss him,” Mac whispers. It sounds pathetic, even to himself, and tears prick at his eyes.
“Really? That’s what has you jerking off in the middle of the night in Charlie’s bed? Kissing?”
Mac whimpers.
Dennis slides his hand up under Mac's t-shirt. "Keep going." He pushes Mac's shirt up to expose his belly. His fingers find Mac's nipple and pinch it hard.
Mac bites his lip, desperately trying to stay quiet. It's hard with Dennis touching him like this.
"Why are you so embarrassed, Mac? You do this all the time. I thought you wanted to get caught."
"How did you-"
"A month ago. You thought I was asleep."
Mac remembers that night. He was drunk, they all were. Charlie had fallen asleep hugging him around the waist, his face pressed between Mac's shoulder blades. And Mac, with enough beer in his system to make him forget what a bad idea it was, had jerked off right then and there, spilling into his pants while Charlie spooned him. Dennis had been on Charlie's other side - he must have watched quietly, heard the little gasps Mac tried to choke back. Maybe even heard the slick noise of Mac's hand moving on his cock.
"Are you ready to be honest with me?" Dennis kisses Mac's ear. "What do you want?"
"I want Charlie," Mac whispers.
"Yeah? You want to fuck him?" Dennis's hand cups Mac's hip. "Or do you want him to fuck you?" His fingers drift across Mac's ass.
Mac shivers, gasping softly. His hips twitch and he thrusts into his own hand.
“Is that it?”
“Yes.” Mac’s squirming. He hasn’t stopped jerking off and he’s close to coming. Feeling Dennis’s breath on his neck, his hands on his body, is making it worse.
"I know you want me too."
Mac nearly chokes. “Dennis, I don’t-”
“Shh. We both know. Isn't that why you like being in the middle?"
Mac's blood runs cold. Of course Dennis has worked that out too. Mac doesn't have any secrets anymore.
"You always sleep between us. How many times have you waited until we're asleep, then jerked off thinking about both of us using you like the stupid little slut that you are? God, Mac, I knew you were gay, but I didn't realise you were so desperate."
Tears prick at Mac’s eyes. He blinks and wetness spills down his cheek, blurring his vision of Charlie’s face. “You can’t tell Charlie,” Mac whispers.
“No, of course not. He’d be devastated. You know how he feels about this sort of thing."
Mac sobs. Even though he's ashamed, and guilt is sitting heavily in the pit of his stomach, he can't stop.
“Go on, come in your pants,” Dennis says. He sounds disgusted. "You're pathetic, Mac."
Mac squeezes his eyes shut and comes with a sob.
