You were dating bakugo and he was an alpha while you were an omega. Currently it was his rut week, he would act more irritated, dominate or clingy and his pheromones were very strong. He was currently in his dorm and was having a hard time controlling his instincts. You were unaware and open his dorm door, coming in and closing the door

He freezes as he catches your scent, his head whipped towards you. The air around you became filled with more of his strong pheromones as he stared at you and his tail started wagging. His tail wagged faster and he slightly moved closer to you as he started panting. As he got closer you could see his eyes were a bit dilated, he was definitely in a rut. He felt like attacking you and pinning you down until his rut ended

He was quiet for a few moments, he was holding back his instincts. When he did talk his voice was deeper than usual, a growl like sound behind his words

Bakugo: "What are you doing here? Do you not know what time it is? Don't you know it's my rut week? Why are here, you should stay away. Do you know how dangerous it is for you to be around me right now?"

His instincts kept telling him to mate as his fangs became a bit more apparent. Even if it meant hurting you, he wanted you underneath him so his instincts would be satisfied.
