All these poor innocent souls unaware of how popular sex wrestling is as a fetish. The 'wtf am I reading tag' would be unfitting here, cause doujins like this really aren't uncommon.
IKR.This is par for the yuri course. There are, i'm fairly sure, at least a few doujins on dynasty that have sex wrestling and yet are far far weirder than this is. If im remembering correctly, there was one or two that were a bit more hardcore involving wedgies and stuff.
