Kingdom Hearts, Cloud/Leon, without having to explain
Cloud tends to stare out over the city walls, looking off towards the dark castle, the old forest, the mountains. The direction isn't always the same; it's wherever Sephiroth has fetched up this time, always just close enough to be within sensing distance. By the time Cloud reaches the place where Sephiroth was, the man will already be gone, so Cloud doesn't bother. Not until he can't stand it anymore.
It's Leon who usually patches him up afterwards, lips pressed in a hard line as Cloud refuses to flinch. Cloud doesn't like to waste potions on Sephiroth's messes, doesn't like to bother Aeris for her spells, but Leon has a way with old-fashioned bandages and antiseptic, doesn't listen when Cloud growls that he's fine.
Leon doesn't ask for explanations on the days Cloud turns away from the walls and goes looking for something else, finds Leon in the computer room or at some construction site, meets hazel eyes briefly and vanishes just as quickly. If Leon can get away, he's going to find himself in an alley with Cloud's hand down his pants, Cloud on his knees with Leon's hands buried in his hair, pulling his head into each thrust. He's going to come hard and fast and quiet, and Cloud is going to be gone before Leon gets his belts settled again.
If he can't get away, Cloud is going to fuck him through the mattress, and sometimes he makes more work for himself on purpose.
In the morning Leon gets up and makes coffee while Cloud is still sleeping, stretched out across the bed like he owns the place, belongs there. Leon almost never wakes him up, but he watches the man sometimes, leaning in the doorway with a steaming mug in hand, appreciating that boneless sprawl.
When he does wake Cloud up, Cloud hums unintelligible things and stretches out lazy and comfortable beneath him, not rushing, content to let Leon do all the work. Mornings are Cloud's favorite time, and Leon doesn't ask why, doesn't ask about any of the names that might spill from the man before Cloud wakes up enough to censor himself, ignores the fact that he's quietly pleased at least one of those names is his.
