Fxxking Teaching

Summary

Soo Sunghyun has a crush on his best friend, Jeong Junyeon. While training Junyeon's younger brother, Jaeyeon, Sunghyun occasionally noticed faint pheromones coming from Jaeyeon, who he believed to be a beta. One day, after getting caught in a torrential downpour, Sunghyun discovered that the clothes he had received as a gift were drenched with pheromones. In response, Sunghyun was sent into rut and found himself jerking off to the sound of Junyeon's voice..."What sort of crazy omega would spread their pheromones like this...?!"
