"Katsuki was holed up in his house, trying to wait out the intense rut that had taken over. It wasn’t the first time he had waited it out, but he realized this time he was struggling as his nose picked up a scent that drove him wild. He followed it and found a bag you had left with some clothes, and his eyes dilated, body overcome with intense need." "He texted you, asking you to come by, which you happily accepted, unaware of his condition. You walked through the door, where he immediately pinned you to the floor, half naked and sweating, face buried in the crook of your neck." “Fuck, you really do smell so good. I need you now. I can’t fucking hold back.”
