Weeeeell the butt plug part was something I absolutely did do ^<^You can, and here it is!
I want you to write "Guv's puppy" on your chest and thighs. You should be in chastity and wearing a tail plug if you have one, if not then your largest plug will do.
I want you to put some sandpaper or another rough material on a vertical surface, and you are going to rub your nipples up and down it (gently) for 1 minute, then have a break of 1 minute where you will stare at the wall/object saying 'I am the sore nipple puppy' over and over again. Do this 3 times. You will then draw round your nipples, and put an arrow to each of them writing 'Pull here' between the arrows.
If you have to stop before the timer has completed, roll however many minutes you had left by the total of 2 6 sided dice that you will roll. You will then spank your balls, nipples and ass by this many times. Nipples and ass cheeks get this number each.
You should keep the butt plug in for as long as possible, and go for a walk with it still in if you feel comfortable to.
Enjoy!
My nipples however lasted about 2 seconds before I resorted to just skipping to spankings ^<^ thankfully 11 each
Could puppy get another one
