I once had a friend spank me in a diaper for fun.
I also spanked him as well in a diaper.
I sometimes will use a belt or a paddle to spank myself when in a diaper.
I will sometimes bend over and use the paddle or a belt to spank my legs below the diaper and tell myself that I'm diaper punished.
I pretend that I'm my mother or dad and pretend that I must be in the diaper and not to take it off.
I wish I had someone to diaper punish me for real and spank me if I try taking the diaper off.
I also pretend that I hate being in the diaper and act upset and then I get the paddle or belt out and spank myself and then say okay, okay enough I'll stay in the diaper just stop spanking me. lol
It's really fun but would be even more fun to have someone else to actually do it to me.
