He's just being a good brother, right? This is what any good alpha brother would do.
What else was he supposed to do? Let his poor baby brother deal with his first heat alone?
Of course, neither had expected the heat to be nearly two years early, the boy only being 11 yet his heat so much stronger than it should've been. It had started suddenly with Hop having a fever one day and being a moaning, drooling, dripping mess the next.
Leon was in the room when the heat really kicked in. He was just there to check on his fever when the smell of slick made his mind go blank. He was sitting beside Hop's bed when the preteen abruptly kicked off his blanket, whining and grabbing at Leon. Tears were already welling in his eyes while he rubbed his thighs together desperately.
"L-Lee, what's- ah- what's happening?" His voice was shaky and sent his brother's thoughts to a mile a minute. On one hand his alpha instincts told him to comfort this distressed omega, do whatever he needed and pleasure him through his first heat- but on the other hand he was still just a child, let alone his brother and he knew they'd both regret it afterwards. But while he was consumed with his thoughts he hadn't realized Hop already tugged off his clothes, on the verge of sobbing but still holding on to Leon's arm like his life depended on it.
"Hot. Why is it so hot? G-god it hurts- Lee please-"
Fuck, no no no, Leon shouldn't be doing this- he shouldn't be pulling off his clothes like he is- knows he shouldn't be climbing into Hop's bed with a mind clouded by rut- but it was hard to stop with this untouched omega whining so sweetly. Hop was just his innocent little brother, he shouldn't be as hard as he is for him. By now the boy was truly crying, nosing desperately at Leon's neck, scenting for any kind of comfort.
Their movements became frantic, nipping at each other's necks, hands wandering with little thought. The alpha pulled away for a moment, any rational thought clouded by his rut, and slid down, pushing Hop's knees up to his shoulders with no resistance. Deep down he knew he should at least prepare Hop, he was far too young to just be taken like Leon wanted to do but he couldn't wait any longer. The position let even more of Hop's amazing untouched scent reach him, leaving the only thought in his head to be claiming the omega before anyone else could take him.
Leon started thrusting wildly, distracted by Hop's shockingly sexy crying that only got louder as Leon's dick traced over his own and spread precum on his inner thighs. It was only a few seconds before Hop got impatient at being empty and started squirming more, grabbing at Leon to pull him closer, using the little leverage he had to finally get his brother inside of him.
Hop's moan sounded more like a scream when Leon finally entered him. The pain of having no preparation besides the slick leaking out of him was completely forgotten and left only the waves of pleasure. Leon was much bigger than he'd thought. The man in question was fully hunched over his brother, jack hammering as fast as he could while lapping at the scent glands in Hop's neck.
Leon was by no means a virgin, being champion gave him his pick of omegas, betas, and sometimes even alphas, but he'd never had an omega in heat. He was completely ruined for anything else. Hop clenched him so tight every time he pulled out yet took him back in with no problem. His small omegan structure very much helped, the curve of his hips giving Leon a handhold to push him down onto his cock while still being perfectly tight.
Neither of them would make it long but Hop would be the first to cover their bellies with cum. He was keyed up from his first heat paired with the fact that this had been the first time he'd done anything really sexual other than some embarrassed humping of Leon's pillow that didn't lead to anything.
The sounds his little boy made pushed Leon into finally knotting him, Hop squirming and whining as he was filled to the brim. The alpha leaned back, slightly tugging his knot, the movement allowed some of his cum to dribble back out and he could almost feel himself cum even harder.
The bliss disappeared the moment his orgasm was done. The waves of their shared heat and rut calmed and left them only with the realization of what they'd done. Leon faltered and opened his mouth to say something but was immediately cut off by Hop wrapping his arms around his neck and tugging him down for a hug.
"Talk later. Cuddle now?"
Leon could never say no to that face.
