5 year BDSM/Engagement anniversary

It's officially been 5 years since I've been with my Master ♡ he bought me a new collar with a tag and I have a new pup outfit to wear for him this week. Any ideas as to what we should do for our anniversary? We have some plans but for kinky stuff, imma need some ideas heheh
