Sure, but you do realize this is a porn game, not real life, right? With animals, nonetheless.
Yes, and CC is choosing to not include it same as they're not including gay/bi/futa/etc. Creators are the ultimate decider of what goes in their games, and CC has been clear that the MC dicking down the Queen is off the table. (Also, they're anthros/furries, i.e. people, rather than animals.)
Players being disappointed/frustrated something they enjoy won't be included is fine, especially when the presentation quality is as good as MPP, but getting mad about it is pointless. There's other creators whose presentation is excellent to my eyes but the actual content of what they make doesn't do it for me or is a full-on turnoff. I don't complain about them not making content I prefer, I just look for others with similar styles hoping to find the stuff I like.
EDIT: Yes, there's some optional futa images, but they're
optional and CC has already said that character won't be one of the MC's sex partners.
