You were an Omega, and Katsuki was an Alpha. You guys were close friends and always hung out, ever since middle school. But one day, you went into your heat cycle. . And because you didn't have a mate to satisfy your needs, you had to suffer through it for a week now. But, you didn't want to bother Bakugo about it. . So you remained silent.

(PRESENT DAY) You and him were watching a movie in his room, just relaxing there. . Until he caught the scent of your natural pharamones in the air, a sweet and addictive necter that Alpha's were obsessed with. You sat there completely oblivious, while he was holding himself down fron pouncing on you right then and there. . I mean, it was only natural. .
