Before I spend money on it, I wanted to ask if there is any spanking that happens in this game. Spanking is kind of my number 1 kink. So I wanted to ask about this before I purchase it. Anyway, anyone feel free to chime in or let me know!

Yes, there is! 
I think there are 2 scenes dedicated almost entirely to spanking asses, with options to spank with paddle, bamboo crop or palm of your hand. These are animated. 

There are also several scenes in which you can spank the character as an option. There are also 2 foot-spanking scenes (I think it's 2 at least)
