Indulgent Omega

Ichiya Hirose, an average alpha enrolled at an elite prep school exclusively for top-level alphas, and the transfer student Yuu Hirose, become completely engrossed in each other the moment they lay eyes on each other, their bodies responding as though on their own. One day during swim team practice, Ichiya goes to check in on Yuu who seems to be feeling under the weather. He is struck by an intensely sweet smell and sees Yuu there in the throngs of pleasure. Stunned by the sweet-smelling pheromones excreted by Yuu, who he thought was an alpha, Ichiya's rationality begins to crumble before this aroused, beautiful, slutty omega. Drawn together inexorably by pheromones, what is the fate of these destined mates...?
