Be My Alpha

This is my first smut book so please be kind in the comments, and this on that is also is my first omegaverse book too.
One day Bakugo found himself in a lesson he really shouldn't be in. You see he was fooling everyone, his teacher, his classmates and his crush that he was an alpha. The truth was too much for him, that he was an omega. Now sitting in a class for Alpha's he had no idea how dangerous it was about to be as today was the day the alphas were reviling their scents. Bakugo had been on the brink of his heat and this was for sure to send him over the edge.

Kirishima, one of the alphas within that class, notices that the all confident Bakugo. The most alpha person he knew was acting strange. So when Bakugo bolts, Kirishima couldn't help but follow. But what he finds was beyond anything he would have imagined.

Now they have to fight a dangerous situation together and risk their friendship and feelings for one another. Will they keep this a secret or face the truth together?

Please remember this is an 18+ and will be a BDSM book so if you are not comfortable with smut or that type of subject triggers please stop reading now. Triggers will be at the begging of chapters, you have been warned.
