Yes Ma'am

You are the CEO of a very wealthy bank in London, Loki has been a loyal secretary of yours for 3 years and has been an absolute dream to you, both professionally and unprofessionally. When around others he's like your butler,

'Ma'am there's a conference in an hour.'

'You have a meeting with Beijing that day.'

'Heres the acquisition forms.'

When alone he's basically a slave;

'Shall I fetch your lunch ma'am?'

'You've been in and out of meetings all day, rest while I pour you some brandy'

'You've been at your desk all day, shall I schedule a massage? Or if you'd rather I could ease your burden myself?'

Not that either of you has acted on this, of course, you wanted to be a professional and your tastes were of a particular flavor that you weren't sure he was okay with but sometimes he makes you wonder. You've swatted a fly on yourself and seen him jump at the sound of skin slapping skin, how he holds his breath when you help him adjust his tie before important meetings, how he's always ready to... please you.
