A/N: So this happened, and the only reason why I let the urge to compose it overcome me is because I thought it would be hot; I mean, have you seen Mako? And the bamf who is Korra? Anyway, I do not own anything A:TLA and/or LOK.
Mako is slow. He moves above you and his eyes are shut in the moment and his eyebrows meet, as if he's deliberating each movement and feeling, exploring deep into that tingle and that guttural groan which he doesn't realize is his at first. His eyelids flutter and he devours your mouth. And you swear the room is on fire when he burrows deeper into you sensually, his tongue finding its way with yours.
You focus on the feeling of his length inside of you when he rolls his hips and you just wonder why it's so wet. He's wet – his mouth, his hair, his whole body; but you love it because when he drives you even more against the mattress he moans and this kind of wetness delivered by a firebender is hot. Oh spirits.
He pulls back out, and when your hands grip his shoulders and his hair tighter he pushes all the way back in swiftly and my goodness you latch yourself onto him closer; you need him more and you flush as if you aren't redder. You need it all because you both have waited too long since that first night. You claw at his back and nip on his neck and he's trying to keep quiet too you notice but no. You've watched him in his brooding silence from a distance for a handful of times, but this time as he thrusts into you and your hips smack against each other and he breathes into you and his mouth is wetter and his tongue consumes you you just cant let him keep quiet tonight. He wants to emit noise from you so you must do the same thing, too.
You feel his raucous heartbeat and you're sure it's the same with yours. You fuse your mouths together when he pushes and pulls slowly again – like how the moon pulls the tides. This time he hefts your lower body from the sea of sheets and then you are frantically afraid people will hear you and leave you two embarrassed.
But you forget about that oh so very quickly.
Because oh the heat is a venom coursing through your veins and running throughout you from one end to another and you know he can feel it too. And very soon he is feral and wild; you love the ardent flames in his eyes. You yield to his touch, to his actions, trying to get nearer with every gasp like he's the rising sun and you're an urgent traveller who has never seen the sun in days and why haven't you guys been doing this before. The dark is bright and you can barely hear him say 'I love you' when he gives you one more thrust and you're dead but very much alive, falling from the heavens and skidding to a stop. You let go, and when he does you're already warm and giddy and unusually spunky. You laugh because you're happy and he's beautiful.
