One thing that has been getting a bit of an annoyance issue is that there seem to be a bit of a disconnect between various writers as to what constitutes a big or even massive dick in this setting. In COC1 that was for the most part a lot more consistent I felt, that "normal" sizes (4'' to 12'') were basically small as far as that game was concerned and you'd have to go into "improbable body ratio" levels to actually get to huge, but it seems very disjointed in this game between different writers. Some seem to think that Lyla, Eryka, Evelyn and Arona (7'' to 12'' all of them) have "massive" dicks or even "titanic girths" and similar, and other instances seem to more accept that those sizes, while huge for our own mundane world are actually normal to small for this hyper fantasy world and it's Brint (20 inches or so) who has the massive dick. For comparison, the PC in this game can attain an almost 50'' "conjoined twin" schlong potentially through a combination of well hung and centaur pack shenanigans.
Making the situation more silly is that there are a few scenes that don't even bother looking for sizes. Majority of the game, if you show up with a stupid-level dick the NPC will remark on it and then there will be a mention of you not being able to fit it all in, which is great and realistic for anything not magical like a demon or at a minimum Minotaur or Centaur sized. But there's also a portion of scenes that don't care at all, for example I did Lyla's dom cowgirl scene right now, and she never cared that I had x4 times of dick size on her and immediately went mashing hips together, despite realistically speaking that would leave her literally impaled when considering her torso length. Other scenes will do both, and remark that there's no way you can get any further or have the NPC protest, and then knot them anyway at the orgasm. And while Brint or even Kasyrra will remark in scenes if you are getting to stupid levels yourself, others like Meira (24'') will always think she's bigger even if you are very close to twice her size.
It's a bit annoying and disjointed in all, and it's left me most of the time just "settling" for a normal 10-12'' for most characters and then go up to 16-18'' max for "gigantic" characters, but then there's instances like Frost Giants blowjob scene (greys out if you aren't stupid level) or Marefolk Shaman scene (does basically SPH on anything but stupid levels) and a few others that does take into account or even require massive sizes, just further adding to the annoyance. By now I really wish we could have a magic "one size fits all" dick (which going by TF description tentacle dicks should be, but aren't, unless you post-TF pick up size increases they are 12'' and will be treated as such with no regard for that fancy TF description in majority of scenes) that would be "big enough" for all scenes that matter. Fuck, I'd be willing to undertake a massive, grueling and expensive quest for Evergreen if that's what it took.
