A few things I don't understand in the story:
1) Why the MC's father really need the MC for that job, if he already has Jackson, who seems to be gay and very... experienced?)
2) Why would Jackson and the MC stop sleeping with each other after finding out that MC is the son of the boss?
Imho, it would add a nice tension, if the MC were more shy in the beginning, and Jackson would seduce him into all sort of kinky stuff slowly)
