A classic scene and I almost have worn out my video tape of it. I remember catching it on cable one night and searching to find out when it would be on again so I could tape it.
I like the fact that it's several swats and they actually show the paddle making contact. I wonder if they used the actresses' real bottoms or stunt butts LOL. I also remember sister doing the paddling was practically licking her lips at the chance. For a vanilla movie not bad at all.
Funny though, I really don't remember the rest of the movie
