Switching it up (m/f, anal, pegging, oral)

So thought of make a post about what I’d love to have happen when I’m next home from working shifts.
Now normally I(M37) am the dominant one in the relationship as my username implies and we actually have a D/s lifestyle most of the time. I’ll write this story style, mostly because work is boring and itll help pass the time.

However, I’d love to switch with her(F27) for a day/night. I’d love to have bath only to find that when I get out that my clothes are missing and instead is a bag with a note cellotaped to it.

The note just reads “These are the clothes you’ll be wearing tonight and the items you’ll need”
I tear open the bag to find a buttplug, some lube, a cock cage and some scraps of material.

I take out and put on the cage, then quickly lube up and slowly insert the plug. Looking at the scraps of material I realise that the scraps are actually holdups and some small panties and a bra.
“Dammit, alright fine I’ll wear them” I mutter to myself. Pull the holdups on and then the panties, covering the cage and then fight with the bra before it finally fits in place.
