Heat hurts, Hanzo learns that quickly. The first time was the worst, his father had locked him in his room with only himself and his fingers to try and sate that biological, unquenchable thirst. He’d sobbed and cried into the sheets, twisting desperately and wishing for something, anything to ease the deep throbbing between his thighs. That had been a nightmare which haunted him to this day. He’d been young then, and Genji younger still. Hanzo had known, for all that he was –the first born, the shimada heir– that his presenting as omega had displeased his father enough to punish him in such a cruel manner.
Sojiro still tries to shut him away in his room, like he’s the family embarrassment for being this way, for not being able to control the way his scent flares up and slick drips between his legs the moment his heat strikes. Hanzo doesn’t even try to talk about it with him anymore, at least, not since Genji presented.
They’re family, Hanzo remembers Sojiro telling them, so they shouldn’t be affected by each other. The thought makes Hanzo want to laugh, remembering all of Genji’s furtive glances at him in the days after his heats, when he knows he still smells like sex and omega pheromones. Eventually they stop skirting around it, one night when Hanzo is tossing on his futon, four fingers buried deep in his cunt, face shoved into one of Genji’s t-shirts. It’s something that fills him with so much shame, but Genji smells like alpha, like home, and it makes the worst of his heat sickness easier to deal with.
