If someone would ask me: What would be a perfect Master evening for you?
My short answer would be: Evenings where my slave serves me on a high level and with the deepest devotion. Of course there is also a long version of how a perfect Master evening could take place and there are a lot of ways how it could happen. But here one idea how a perfect evening could be.
It would start while being at work sending my slave the order to take a clean sweep over the flat and to prepare everything for a wonderful evening! In the same time I would perhaps ask another trusted Master-slave couple who would also live the BDSM lifestyle if they would like to join for dinner.
Before heading home I would inform my slave that I will be home soon and he should get prepared like trained! - "Yes Sir. Sir? Would you like a welcome drink or shall I prepare a bath?" - That would be an appropriate response for the start of an perfect evening. My slave taking care of my needs.
