It was 2 AM when the door to their apartment slid open and Rodney snuck in, if you could call it sneaking. He needn't have worried, as both his lovers were still awake, sitting curled up naked together on the bed watching The Two Towers on Radek's laptop.
John looked up and smiled. "Hey, where've you been?"
"I was with Carson," Rodney answered, sounding slightly defensive. "Cadman dumped him and he needed some cheering up."
"That's nice of you," John answered, ignoring Rodney's tone. "Did you make him feel better?"
"Just what are you asking?" Rodney demanded.
John held up his hands. "Hey, calm down. You don't have to share anything you don't want to."
"Open relationship, remember?" Radek added.
"I just happen to like Carson, too, and don't like seeing him look like someone just killed his puppy," John finished.
"Sorry, sorry. It's just... I'm still not used to this and Carson... well, he kind of freaked."
"Mm," Radek said. "Freaked how?"
Rodney waved vaguely. "The, uh, whole sex thing."
"So, a heterosexual freak out or an 'Oh, my God, Rodney's lovers are going to kill me!' freak out?" John asked.
"The second. Carson's about as straight as my piloting, or hadn't you noticed?"
Radek chuckled. "We've noticed."
"Actually, we'd talked about inviting him to join us a few times," John admitted.
"Really? Before or after you talked about inviting me to join you?" Rodney asked.
John shrugged. "About the same time."
"So I lucked out because he started dating Cadman?"
His lovers both gave him puzzled looks, then Radek closed the laptop, set it aside and stood, taking Rodney's hands and pulling him toward the bed. "We chose you, milacku. It had nothing to do with Cadman."
"Really? Why?" Rodney asked as John got up on his knees on the bed behind him and began removing his jacket.
"You're really an idiot sometimes," John answered, voice full of exasperated affection, then kissed his shoulder.
Radek reached for his fly and began divesting him of BDUs and boxers. "But we love you anyway."
John pulled him onto the bed and slipped Rodney's shirt up, hands trailing warmth on his skin as he did so, and Rodney gave up. He'd never entirely understood what had motivated the two to invite him into their bed and their lives.
Radek knelt to pull off Rodney's shoes and kissed his thigh and then hummed appreciatively. "You smell like sex."
"Mm. Yes, he does," John agreed and shifted to kiss the other side of Rodney's neck. "Hm? What's this?" His tongue flicked out and traced the bite mark he found.
"Uhm... It's... uh... God, that feels good!"
Radek pushed Rodney's legs open, trailing kisses up his inner thighs, fingers teasing his balls, touching the smooth skin behind. Rodney's breath caught as Radek's fingers slid further back. "Oh, Rodney! You're so slick..."
"Ung... ah... I..."
"Inside and outside," Radek added when he had verified that fact.
"Lube?" John asked.
"Come," Radek answered.
"Rodney Ingram McKay," John chided, though his voice was low and rough, "I do believe you've been barebacking for Carson."
"I... Yes, but..."
"Do you know how goddamned hot that is?"
"Wh--"
"Now I'm going to have to fuck you, too... Pump your ass full of my come, mix it with Carson's... And then I'm going to watch Radek fuck you till you're so full you'll be dripping... Do you like the sound of that?"
Rodney made a sound halfway between a moan and a gasp.
"Was that a yes?"
Radek and John had discovered within days of taking Rodney as a lover that they could reduce him to a quivering mass of wordless need by simply telling him exactly what they were going to do to him. Rodney could barely breathe, but managed to nod.
"What do you think, Radek? How do we want him?"
Radek slipped onto the bed, sitting at the head. "Hands and knees, with his mouth right here," he answered, fingering his cock, already dark and hard and dripping pre-come.
Rodney needed no encouragement, scrabbling onto his hands and knees at once, ass pointed at John. Radek kissed him once, deep and hot and wet, then sat back and watched with a half-smile on his face as Rodney lowered his head and sucked the full length of Radek's cock into his mouth.
"Oh, yes," Radek hissed, petting Rodney's head. He looked up and smiled at John who was watching the two, his eyes dark with desire.
John positioned himself behind Rodney, watching even as Radek watched him, fingered Rodney, feeling how very slick he was, and then guided his cock in a slow, exquisite slide into his lover, sheathing his whole length. He and Rodney both moaned. Radek gasped at the sensation of it passing through his cock.
John withdrew with agonising slowness, then thrust back in suddenly. Rodney let out a gasp of surprise, releasing Radek's cock. Radek leaned down and kissed him as John set up a fierce rhythm.
"God! You're so hot and so slick..." John moaned.
He'd fucked a semen-slicked Rodney many times before, loved watching Radek fill him and then take him as well. But somehow the knowledge that it was Carson's fluids that coated his cock inside his lover drove him mad with need. He wondered what it had been like, imagining Carson fucking Rodney against a wall, bent over his bed, or perhaps Rodney had ridden Carson's cock, fucking himself on Carson's meaty erection. It only took a few thrusts before he found the heat building in his balls and then filling his cock with pulsing pleasure. He continued to pump, churning his semen and Carson's together inside Rodney's body until the sensation became agony and he pulled out.
As he collapsed next to Rodney, Radek crawled down the bed and took his place, holding Rodney's trembling hips steady as he thrust into him. Radek slipped a hand around Rodney's waist and grasped Rodney's erection.
"Rodney, did you fuck Carson's ass?" John asked.
Rodney shook his head. "He... uh... sucked... ah... me off... God!"
"Good," John said, and wormed his way under Rodney's belly. He slipped his hand around Radek's, steadying the other man's rhythm, allowing his lover to concentrate on his own pleasure more. It was an awkward angle, but he leaned up and took the leaking head into his mouth, sucking and his hand slid forward and back with Radek's.
Rodney's breath was growing ragged and he was letting out little moans with each of Radek's thrusts. Radek excelled at finding just the right angle to tag his lover's prostate and John knew from Rodney's vocalisations just how much pleasure Radek's cock was giving him.
It wasn't long before he felt Rodney's balls drawing up. He pulled his and Radek's hands away and leaned up, sucking Rodney's cock deeper into his mouth. It pulsed and the bitter, salty flavour of Rodney exploded into his mouth. He drank it down, each swallow eliciting a gasp from Rodney.
Radek let loose a string of Czech and surged forward, driving Rodney's cock deeper into his mouth. Both his lovers moaned and he couldn't help but smile around Rodney cock. He loved to listen to their voices raised in pleasure, the music of delight. He released Rodney's cock and relaxed back on the bed, closing his eyes.
"John," Rodney's voice startled him and he realised he had been drifting off. "You need to move, please."
He quickly slid out from under Rodney, who immediately collapsed as soon as he was clear. He laid out against Rodney's back, head resting on the broad shoulder as Radek mirrored him on the other side. He leaned forward and kissed Radek, sharing Rodney's taste with the other man, then settled again.
He was drifting off again when Rodney said, "So... you really don't care that I, uh, had sex with Carson?"
"Oh, we care," John answered. "We just don't mind."
Radek leaned down and kissed Rodney's back, then smiled across at John. "Perhaps we should reconsider asking Carson to join us."
"Four of us?" John asked.
"It can't be much more complicated than three, can it?" Radek asked. "Besides, Rodney cares for him a great deal, I think."
"You two are crazy," Rodney said. "Four is a lot more complicated than three. You don't need to do that for me."
Radek shook his head, smiling down at Rodney affectionately. "Oh, milacku, we know we don't need to. We want to. For you."
"Yeah," John agreed.
Rodney turned over, spilling them both off his back, and sat up, looking between the two. "But, why?"
John rolled his eyes. "Because, Rodney... just... because."
"And you call me an idiot," Rodney said.
"It is very simple thing," Radek said. "You care for him, he cares for you and, very obviously, not just platonically. Over the time we have known you, we have seen he makes you happy. We like you happy. So, it's logical."
"Also, he's almost as hot and sexy as you are. Honestly, we'd seriously consider anyone you wanted to bring into the relationship."
"As long as it wasn't Kavanagh," Radek said, grinning.
"Oh, please! Like that would ever happen."
"Oh, hey, I don't know." John smirked. "Have you seen how flexible he is? I'll bet he could even suck his own--"
"John!" Rodney yelped, slapping hands over his ears. "I don't need that image or to know you've actually given this thought. Please!"
John chuckled. "So, Carson then?"
Rodney smiled down at his two lovers, shaking his head. "Yes, I'd like that." He lay back down between them and closed his eyes.
They settled together, drifting off to sleep.
Rodney's voice drifted into John's dreams. "But you two are still crazy." But John could hear he was smiling.
