they're both so much bigger than p!Leo, I bet if they sandwiched him between them you would barely even see him - and p!Leo is just a flustered mess between them, because goddammit this is his twin who dislikes physical contact and super hot and competent version of himself from the future.

F!Leo and F!Donnie already having an established relationship and deciding to mess with p!Leo. F!Donnie making sure to give p!Leo more attention than usual, lingering touches while passing by, subtly showing off his arms and such

meanwhile, F!Leo takes advantage of p!Leo’s admiration of himself - calling him to train to show him some moves, pressing himself against p!Leo's back to fix his posture, casually grabbing him by the waist and leaning towards his face when giving him advice

all while Leo is having a crisis because is he really that narcissistic? did he always feel like that about Donnie, does he need to review their whole relationship? having a whole spiral that just gets shut down the moment F!Donnie puts a hand on his shoulder while asking him if he wants to spend evening with him and F!Leo while everyone else is out. Splinter is on vacation thanks to Barry, humans are at April's and the boys are probably on a patrol, it's been pretty quiet after the invasion so while thinking it's a bit weird they don't mind when Leo tells them he's hanging back with the future twins

the moment Raph, Donnie and Mikey are gone the game between F!Leo and F!Donnie starts - who can crack down p!Leo first. if p!Leo was flustered before, now his face matches his markings. pressing p!Leo into their sides, talking right beside his ear slits, at one point they play some games together and p!Leo keeps losing because he's too distracted by their hands on his thighs.

eventually, p!Leo ends up in F!Leo's lap with F!Donnie right next to them, when it gets too much and he finally gives up, grinding onto F!Leo's thigh. immediately after everything freezes, before F!Leo chuckles and grabs p!Leo's hips and pushing him down as he's moving his leg up, grinding p!Leo onto his thigh just like he had done so himself moments prior

F!Donnie, watching all this joins into the action and starts whispering sweet filth into p!Leo's throat, one of his hands moving to squeeze p!Leo's tail, making p!Leo drop into his shorts. it's not long before they have him moaning and twitching, nearing p!Leo's release when both of them abruptly stop. p!Leo doesn't even realise he started whining until he feels fingers at his entrance, pushing into him before he has a chance to protest. the burn is there and it's extremely uncomfortable, even with how wet p!Leo is. the digit starts moving inside him, stopping shortly after with a small 'tsk' and mutterings about needing to fetch lube.

the Leos wait together for Donnie to return, F!Leo checking with p!Leo that he's actually okay with what's happening and getting positive answer in return. F!Donnie returns and pushes p!Leo to sit on his knees above F!Leo's leg, taking off his shorts in the process and throwing them aside, p!Leo winds his arms around F!Leo's neck and F!Donnie moves to stand plastron to carapace with p!Leo. this time with lube, F!Donnie's fingers return to p!Leo's entrance, pushing obscene moan from his mouth. F!Leo starts pressing kisses onto the younger's face, throat, and shoulders, letting out a startled groan when he feels hands on his dick. F!Donnie started jerking him off from around p!Leo, pulling out his fingers and moving p!Leo's arms to jerk off F!Leo. when F!Donnie's satisfied, he moves away from them both and lines up with p!Leo's entrance, smoothly ramming his dick in and bottoming out with one thrust.

p!Leo is seeing stars and the burn is back, just as his cock is weeping from the lack of attention but he's too far gone to do anything except to keep begging for more and grinding back onto F!Donnie's dick. he drags p!Leo further down on the couch as he's pulling back his hips, until p!Leo is low enough for F!Leo to push p!Leo's head onto his dick. not giving p!Leo any chance to adjust to the new position - F!Leo knows himself, knows he likes it rough - F!Leo starts sharply thrusting into p!Leo's mouth while F!Donnie sets a brutal pace, sighing his claws into p!Leo's hips. F!Donnie and F!Leo synchronise so they're pushing in at the same time, stuffing p!Leo from both ends at the same time. with a particularly rough thrust from F!Donnie, p!Leo lets out a high-pitched wail around F!Leo's cock, strangled curse the only warning he gets before F!Leo is grabbing him by his nape and pushing his head down until he's choking on his dick with snout pressed against F!Leo's pelvis, cum shooting down his throat, giving him no choice but to swallow.

F!Donnie continues to slam into p!Leo, intent on making him cum untouched, right hand on p!Leo's hip while the other keeps squeezing Leo's thigh and ass. knowing he's not gonna last long, he bends over and sharply bites down on p!Leo's shoulder, strong enough to make him thrash and start warbling around F!Leo's dick still lodged in his throat. with one last powerful thrust F!Donnie pushes over the edge, his load shooting inside of p!Leo setting off his own orgasm. when F!Donnie's caught his breath enough, he pulls out and gathers p!Leo into his arms with shaky legs, heading for the bathroom. F!Leo cleans up after their activities before joining them in the shower for the 2nd round.
