This chapter happens a couple of minutes after the last chapter, a few more minutes after chapter 28 of IWIHaA, and the day before chapter 31 of IWIHaA.
Warnings for this chapter: Forced heat, sex, Alpha/Omega mating
Law is wrapped in a duvet, trembling and swaying on his feet; eyes wide and wild, pupils dilated. Kid's head is swimming from the amount of pheromones in the air and Law's breathtaking smell, but he manages to hug the Omega without ravishing him. Law has no such qualms and pulls him down into a kiss that quickly morphs to an insistent slide of tongues and breathy sounds, the Alpha pressing the Omega up against the wall. Law's arms are tight around Kid's neck, the duvet barely clinging to him, and Kid explores the bare skin eagerly, lust mounting as Law arches into his touch, moaning and wriggling.
"Kid," he whines against his lips as the Alpha cups his slightly round chest in his hands and Kid grins as he pulls away to kiss down his jaw before moving down his neck. "Ah!"
"You're beautiful," the Alpha whispers. "Beautiful. I love you."
"Love you too," Law groans, unwinding his arms from his neck to tug at his t-shirt. "Off."
Kid chuckles, pleased, as he takes a step back and tugs it over his head, throwing it away as Law steps towards him and pulls him down into a brief kiss. The older teen tries to deepen it, but Law pulls away, gently pushing him away.
"Bed. Trousers off."
"Are you sure?" Kid asks. "You don't have-"
"I want, Kid. I want you."
Kid swallows and nods, not trusting his voice. Law smiles up at him as he slips around him and heads for the bed, dropping the duvet to the floor. The Alpha kicks his boots off and tugs his trousers down, stepping out of them on his way to the bed, where he wraps his arms tightly around the Omega and kisses him deeply. Law kisses back as he pushes him down onto his back and tugs at his boxers, Kid raising his hips so the smaller teen can pull them down.
"Law," the Alpha moans, startled, as his bonded straddles him and his cock gets trapped between the cheeks of his ass.
"This all right?"
"Prepare-"
"Want to feel it. Want to remember. This all right?"
Kid can only nod, and Law raises himself up, wrapping a hand around his cock to guide it inside himself. The Alpha groans, sliding his hands down to grab Law's hips tight, trying not to come as a tight, wet, velvety heat slowly envelopes him.
"Shit, you're big," Law hisses between pants, eyes squeezed shut.
"Law. Fuck."
Law moans in answer, shifting to place his hands on either side of Kid's head for balance as he starts moving. Kid lets him control the pace for a few minutes, before he begins thrusting up to meet him, moving his arm to wrap a hand around the Omega's cock. A few thrusts and strokes is all it takes for Law to come undone with a garbled moan of his name, Kid flipping them over as the smaller teen shakes apart, continuing to thrust as Law's channel tightens sporadically around him and his knot forms. The Omega whimpers, wrapping his legs around his waist and his arms around his neck, clinging to him as Kid works the knot in and out of his body and finally comes with a groan of his name. They lie together in the afterglow, panting in tandem, Law's body locked around the knot, not speaking. When the knot dissipates, Kid initiates a slower, less frenzied lovemaking, and if he kisses tears from his mate's cheeks without saying anything, no one will be the wiser.
