I once asked a priest if it was okay to kiss a nun. He said yes, just so long as I didn't get into the habit....
Dunno about sin, but there are several states where it's illegal to even own
But it's an interesting point. If the husband cared enough to provide his wife with several "toys" to use while he was away, then I suppose whenever he left, he would say, "Good-bye, my dear; I'll leave you to your own devices."
You are so silly and I love it!
