Work stuff:
-condoms in variety of sizes
- lube (sachets and massage lube)

- 2/3 changes of outfits with stockings/ hold ups to match
-a few additional items if requested including a crop,  nipple clams and ribbon.
-small bin bag to take rubbish away
-small “candy bags” to dispose of condoms into the bin.

Additional items:

I’m probably missing some items here  but this is off the top of my head.
