You should probably check out instead our spanking sister site:
www.AnimeOTK.com
It doens't have a vast amount of M/M, its mostly F/F, but if you look through the galleries and the search functions are quite simple under the /M folder there is quite a few of that sort of thing~
Not as many as I'd like >_> this site doesn't really have the interest in spanking outside of BDSM-lite and spanking/CP pics don't get a lot of comments, so I don't think its likely to get a huge following here... but if you had anime related pics of that sort, the sister site would eat 'em up~
