Wearing Wifey’s panties

I love wearing my wifes panties when she is not around..
I dont know how to tell her, but would love to wear them when we are having her BF over for the night..
Any suggestions ??
When her BF comes over, you offer to pull her panties off, after you have them off ask the BF what would he like you to do with them, give him options, like masturbate with them or wear them or use them in your face,,
