Styles may differ. I believe she is doing it nicely and strict enough. Also not only skinny guys are suitable for videos. he is an ordinary mature man, and he still needs strict punishment
She's attractive, her clothes are perfect for the occasion. But the acting is bad. First of all she talks too much. And he's an old fat guy he's not suitable for these kind of videos.

Too much bs in this video is a huge turn off.
