Summary
Shame rears its ugly head, grounding his thoughts. He doesn't want to be seen like this, caught in such a pitiful, unmanly state. Tremors wreck his frame as he gnaws on the inside of his cheek. The scent grows warmer as it encroaches closer. Kirishima instinctively strengthens his own scent to match, but not in challenge like other alphas would. Instead, his scent carries a confession he's not ready to face, something that even catches the doctor's attention as she sniffs the air and studies him in her peripheral. He needs to suppress it quick, but the charred aroma continues to crowd him, turning his breath ragged and siphoning his control. He groans in frustration, heat burning hotter beneath his flesh. Before he can even try its already too late.
Or: a mission gone wrong puts Kirishima in the hospital at the mercy of a villain's quirk, triggering the rut of his life. Fortunately or Unfortunately, Bakugo decides to bring him home. Will Kirishima be able ride out his rut and endure his greatest kept secret, or will he crack under the weight of his own need?
