After being tortured by a group of hunters, Derek goes into heat. Stiles helps him through it. Written for the 24-hour porn challenge community, Stop, Drop, and Howl.

"I need to—" you can't, you can't say it with Mituna there. "It's my mutation," you say instead. "There are complications." "Okay, dude, open the door," Latula says. The knob rattles, and you miss whatever Mituna says next. "Yeah, I know, but he's still one of us. We can't just let him suffer, you know?" (Kankri misses a social outing. Some of his friends come to check up on him.)

Keith stood under the hot spray of the shower head, his eyes closed as he focused inward, trying desperately to regain some sense of composure. He wasn’t quite certain what was wrong with him today; he was the one moving out of sync in their training exercises, he’d run himself into an invisible maze-wall so hard he was dizzy for a quarter hour after it, and he swore he could still feel the static jolt under his skin. When Shiro had touched his shoulder, eyes concerned, his touch was like a fresh electric current and Keith had yanked himself away.

In a world where Omegas far outnumber Alphas, a dowry system is in place. The Omega’s family offers a dowry in order to secure a respectable Alpha match, with the highest dowries netting the “best” Alphas. Aunt May struggles to secure an Alpha for her Omega nephew’s first heat. All her meager savings can afford is a butt-ugly (by his own admission) Alpha without much experience to speak of. Peter would rather go unmated than lose his virginity to a guy that can’t go five seconds without making a Monty Python reference. However, it seems Peter has no choice…

Just because an alpha can go through rut alone doesn't mean he should. "Okay." Lance's palms were sweaty with what he was about to say. He was about to break so many rules. "Cards on the table, guys. We got any omegas sitting here?"

"We did go looking for omegas," Izuna pointed out under his breath, staring down at his personal enemy. "Look me in the eyes and tell me you want Senju Tobirama for a wife," Madara replied just as quietly, a brief spark of amusement blooming at the shocked horror on his baby brother's face. -- Before he was forced to accompany a pack of rut-muddled idiots on a half-baked plan to kidnap omega brides for the good of the Uchiha clan, Madara hadn't given Hashirama's younger brother much thought. Tobirama was a Senju, and therefore the enemy; he, like Madara and Izuna, was sole survivor of his litter, and so to avoid being alone and therefore unmarriageable had ended up paired up with his older omega brother by default; he was a vicious opponent; he was a beta. He had to be a beta. Hashirama wasn't, and nobody would be brazen or stupid enough to bundle up two reproductive siblings in the same litter, right? ... Right?

Obi-Wan went over thirty years without a heat. It was hardly unusual or unexpected. Everyone knew omega reproductive systems were finicky. Omegas were incredibly fertile while in heat. Nature had, perhaps, compensated for the situation by ensuring they only went into heat when...conditions were correct. OR, the Dark Side AU where the Empire is already in power, the Jedi are long gone, and Obi-Wan Kenobi ends up leading an army to wipe out the Emperor's enemies. Things get more complicated when he goes into heat.

One of the most closely guarded secrets of Wen Kexing's life, more so than his hoarded memories, almost more so than his old name, is the fact that the Ghost Valley Master is an omega. When his heat suppressants run out on the way to Longyuan Cabinet, Wen Kexing is plunged into the worst heat of his life. He's desperate for some kind of relief, but Zhou Zishu's encroaching illness means he's no longer able to perform in that regard — and anyway, he's not an alpha. But Ye Baiyi is.

Beau has a good feeling about this season.

Not long after his confrontation with Bruce and the Joker, Jason crosses paths with an angry Poison Ivy. She accidentally triggers his heat before leaving him for Robin to find. Still scared and angry about the incident at Titans Tower, Tim has no choice but to help Jason work through his heat when it turns out that he's been abusing suppressants and could very well die without an alpha to help.
