Get it Here

I'm trying to find a fic:
-Brian begins working in Justin's company.
-He seems interested in Justin.
-Justin has lots of sweets in his desk (Brian says something like "Jesus, you really like sweet!".
-In the end Justin discovers Brian was trying to bed him because of a bet with a coworker.
-Daphne is Justin's sister (he was adopted by her parents).
-I think there is a second part with Justin in a mental hospital.

Thank you for the help.
