Nope, she got fucked by genetics
>The sexual tension between them was intense
The act of sex its self doesn't increase your CC but sex(especially between coworkers) usually leads to drama which in the end will lead to 1 or both partners with their guts and blood on the walls and ceiling.
Probably not in a normal situation. Things like adulterly obviously won't improve your colour; but consentual sex will -- or rather the lack of sex will taint it. Feeling unwanted is one of the things that will slowly taint your colour.
