Ah, the eternal question of "What is 24/7?"....
As ID and others have alluded to, 24/7 is what you make it to be. Point is this: real lifestylers who live 24/7 have to survive in the real world, just like everyone else. Everyone who lives in the real world and is 24/7 has responsibilitites. Whether it's kids or jobs or school, there's always something. And the bills have to get paid, the home taken care of, the grocery shopping completed. There are very few...scratch that near ZERO... people who have the luxury to live in the fantasy world of a 24/7 sub-stays-home-does-nothing-but-fuck life. And to be honest, that'd be BORRRRINNNNGGG... To stay at home all day and do what?? After the house is clean, there isn't much to do, and staying home in that role would provide what service for yor dominant? For being a submissive is ALL about servitude.
Everyone serves their dominant differently and in their own special ways. Some serve by having a good job outside of the house to help provide additional income. Some serve by staying home and taking care of the kids and making sure to provide for the family in non-financial means. Some go to school and serve thier Dominant by becoming more educated so that they can get a good job down the road. In every case it boils down to the same thing: servitude. People often forget that servitude is at the heart of submission. And I am not talking about the beating, fucking, physical kind of servitude (though mmm... we all do love that part!!!). I am talking about the day in, day out servitude. Keeping the house in order, doing the little things that make your Dom smile-- fetching a towel for them when they get out of the shower, making coffee in the morning, laying their clothes out for them to make it easier in the morning, being at the door with a hug and kiss when possible at night, making a meal...
There are things like spending quality time relaxing together, having dinner together, talking about the kids (if you have them), dealing with relatives, going out with friends--all things that you need in a 24/7 lifestyle relationship just like you need in a 24/7 vanilla relationship.
This is my long way of saying: 24/7 D/s is a dynamic, fluxing experience. You have to ebb and flow with real life, you have to move with the way r/l moves. You can't stay home and be a fantasy love slave all day-- you'd be bored and it wouldn't be realistic... besides which... your Dom WOULD tire of that after a while, no matter what they say lol...
Hope this gives you some help,
