When Kitayama receives a text message from Nikaido asking him to come over and hang out together with Fujigaya, he wonders if Nikaido is aware why Fujigaya wants to hang out with him. It’s barely been a few days since Fujigaya had him over and surprised him with his new, temporary body parts – surely if Nikaido knew, he wouldn’t have invited him?
In the end he makes his way to Nikaido’s apartment not sure what to expect, the only additional information being that they’ve already arrived before Kitayama even left his own apartment. Plenty of time for sex before he gets there, he supposes. Maybe they are just hanging out.
Except when he arrives at an unlocked door and lets himself in, it looks like they might’ve been chatting first and just moved on to other activities.
Fujigaya is perched on Nikaido’s lap, pants off, both of them ignoring his arrival as they’re making out. Kitayama leans against the doorframe in silence, letting the small hums between kisses fill the air along with the wet sound of lips coming together over and over. Except there’s one additional sound, stickier, wetter, and that’s when he notices the underwear that have been tossed onto the floor. And very well, Nikaido has a hand between Fujigaya’s legs, his wrist rolling in movements that Kitayama knows well. From the look on Fujigaya’s face, it looks like he’s doing a good job too.
Slowly he takes one step after another in their direction, stops when he’s right behind Fujigaya and brings his hand up to stroke the back of his neck. The touch startles him, but it only takes a second for him to go back to kissing Nikaido. Kitayama takes that as a sign to go on and he strokes his hand down Fujigaya’s spine, to the hem of his long shirt and then under it. Once there he wastes no time, moves down to where Nikaido’s fingers are inside him, where his pussy is dripping wet. He hesitates for a moment and decides to go with his impulse. When Nikaido’s two fingers pull back he gets ready, and when they push inside again Kitayama adds one of his own. A long moan follows, accompanied by the shift of Fujigaya’s hips as he’s stretched further open.
“Fuck,” he hears from the other side of Fujigaya’s shoulders, and when he takes a peek he sees Nikaido, eyes glued to the face in front of him, eyelids heavy and his pants ready to burst. Kitayama lets his hand slip away and moves the half a step it takes to be able to reach Nikaido, and he’s undoing his pants while paying no mind to possibly getting stains on them. For once Nikaido doesn’t seem to care, much more focused on the man on his lap and the hand that soon wraps around his cock.
“Please,” he hears then, the weakest voice he’s ever heard from Fujigaya, and although he had intended to stroke Nikaido’s cock for a bit, get him even more impatient, he just holds it in position as Nikaido’s hands guide Fujigaya closer. They all moan when he sinks down on his cock, pussy swallowing it in one go and Kitayama feels his own erection aching at the sight of Nikaido’s covered in sticky wet when Fujigaya lifts just a little up.
It’s not like he’s out of options though, he figures, one of them obviously to wait. Not what he wants though, and he leaves the room to retrieve a couple necessary items. Once back he returns behind Fujigaya, this time popping the cap of a see-through bottle. He only startles Fujigaya momentarily when two of his fingers meet the opening to his ass, spreading lubrication over it as he rubs in small circles. He knows Fujigaya isn’t new to this type of sex, and judging by the way he continues to slowly roll onto Nikaido’s cock he isn’t opposed to it now either. That, or he’s too turned on to care as long as it feels good, and to be fair Kitayama doesn’t really care what the reason might be.
The first finger slips inside surprisingly easily, perhaps helped by how Fujigaya’s legs are spread over Nikaido’s lap (and his pussy spread around his cock). There’s a little sound from Fujigaya at the initial intrusion, but the rocking of his hips doesn’t stop and Kitayama isn’t sure Nikaido has even noticed. Once he adds a second finger there’s a little bit of resistance, he needs to push past the tight muscle and it makes Fujigaya stop momentarily, in turn making Nikaido tilt his head to figure out what’s going on.
Until he feels it, or so Kitayama assumes, because Nikaido’s lips part to moan while his eyes widen slightly in understanding just as Kitayama’s fingers slip inside all the way up to his knuckles.
“Nika, lay down on your back?” Kitayama suggests, moving along as Nikaido turns them around on the couch until he’s laying down and Fujigaya is leaning forward above him, one cock and fingers still inside him.
“You’re gonna feel so full,” Kitayama promises in a mumble, pressing his lips to Fujigaya’s lower back and pulling his fingers away.
He rolls a condom on, adds some lube to it, and then positions himself right behind Fujigaya, between Nikaido’s stretched out legs, aided by Nikaido making more space by putting one foot down on the floor. Fujigaya’s pussy is soaked, Nikaido’s cock glistening with the juices from it, and as he moves in they both still. He presses the head of his own cock against the opening right above it.
It goes in fairly easily, little by little as he doesn’t push hard, and once he’s halfway inside Kitayama pauses and strokes a hand up Fujigaya’s spine, palm flat against his skin. He can feel him breathing slowly in a controlled manner, likely forcing his body to calmly get used to the pressure in both holes, and when he hears Nikaido ask if he’s okay, he nods and hums in approval.
Nikaido moves first, maybe subconsciously because it’s a shift of his hips rather than a thrust, but it gets them all started. Kitayama has more leeway seeing as he’s on top, and from the first time he pulls back to push back in, there’s no stopping. Fujigaya’s ass is tight around him, and right next to it Nikaido’s cock is pushing into his cunt, Kitayama can feel it through the wall that separates them. The moans that come as a result to it are deep from Nikaido, but Fujigaya’s are almost whimpers, except he’s not in pain. He’s moving just the slightest towards the intrusion, hands fisted against the couch next to Nikaido’s head, and when Kitayama peeks over his shoulder he catches Nikaido’s hands at the height of Fujigaya’s nipples.
Soon Fujigaya’s legs are shaking, muscles contracting all over his body but especially around their cocks, and Kitayama pauses to wait for what sounds like an amazing orgasm to take its course through Fujigaya’s body. His head is resting against Nikaido’s chest by the time his limbs are getting steadier, and he’s panting, not helped by Kitayama starting to move again.
“We’re not gonna stop. Okay?”
To anybody else it might sound forceful, but they all know Fujigaya would tell them it’s too much if it was, and the fact that he nods and lifts himself back up on his arms means not only is it okay, he wants it. And so they go on, finding a rhythm where Kitayama pushes inside when Nikaido pulls back, Fujigaya in the middle just taking it, both holes stretched and clenching each time they’re filled. Unsurprisingly it doesn’t take long until Nikaido can’t hold back anymore, and when Fujigaya is hit with a second orgasm that has everything tightening again, Nikaido comes right where he is inside Fujigaya. It’s even less of a surprise when Fujigaya tsks at the realization that he’s again been filled with come, but he doesn’t seem to mind all too much once Kitayama starts fucking him faster now that Nikaido is out of the way.
Kitayama watches Nikaido slide out from under Fujigaya to sit in front of him, wasting no time to guide his head towards his cock, and Kitayama takes the opportunity to hike Fujigaya’s hips up so that he’s properly on all fours. Slowly he pulls out, listens to the sounds as Nikaido is getting his cock sucked clean while he discards the condom before he pushes inside his cunt. It’s incredibly wet, and Nikaido’s come spreads over his cock as he chases his own climax. The way the walls around him tighten is easily traced back to one of Nikaido’s hands between Fujigaya’s legs, playing with his clit if Kitayama were to guess, and ultimately it’s his third orgasm that really pushes Kitayama over the edge as well. His hips are pressed flush against Fujigaya’s body, spilling his come as deep inside as he can, feeling that tingle of satisfaction in his unprotected release.
“Disgusting,” Fujigaya mumbles as he lowers his head to the top of Nikaido’s thigh. “Freaks, both of you.”
“You say that like you didn’t like it,” Nikaido replies, clearly mocking him. “Plus, the doctor said you can’t get pregnant anyway, right?”
“And yet you’re trying so hard.” Fujigaya sends them a glare, first one and then the other, but then his expression softens. “I deserve a bath.”
“On it,” Nikaido says, already on his way to the bathroom to get the tub started, and Fujigaya turns onto his side on the couch. Kitayama tries to ignore his urge to look, but it’s difficult when it’s right there; thick white liquid is leaking from his cunt.
“If you don’t stop staring I’m gonna sit on your face,” Fujigaya threatens, only to immediately take it back when he sees that Kitayama isn’t the slightest discouraged by it. “Pervert. Go be useful like Nika, get me a glass of water or something.”
“Pervert, says the one who came multiple times with a cock in each hole,” Kitayama mocks him as he stands up to get a cup from the kitchen. “You loved it.”
