Re: Giant tentacled, furry bukkake in the ass.
Mind control, change, corruption, invasion, and strange behaviour altering things. Tentas, slimes and "exotic" plant life make my favourite monster type things.
Along with most of the above. Variety is good. Then considering how each works combined. Futa works best when in a "yuri surprise" package. No yaoi for me thanks, more for the rest. Can't say I'm fond of furry in general. Ocaassionaly it works, but to often theres something about the typical style that puts me off.
