Some of you may find amusement in the Random Punishment Selector web form. You check a lot of boxes and it spits out a “Punishment Certificate” that’s essentially a road map for a spanking punishment session.
I’m not sure it offers more functionality at the end of the day than just picking up your toy bag and saying “Hey, take down your panties and bend over” — but some people like a bit more ceremony and predictability so they can dread things properly. Also, the numbers fetishists are out there; they want a number of swats and a good count or it’s not as much fun.
I found the link via this Tumblr post, which also links to a couple of other “online spanking programs”.
