My wife's sister spanked me hard like that but for ages and Infront of my wife. When it was unbearable, my wife was laughing at me while her sister spanked my bare bum hard and fast for a long time, they said I deserved it.
My mother-in-law walked in on us, when my wife had me naked over her knee on our living room couch on my 50th b'day. Then she said, she too wanted to wish me a happy b'day, & over her knee I went. Now, I get spanked & peddled by both, whenever they think I need it, or are just in that mood.
