Most AVN MC's have large penises, but the one in this game is 50% bigger again. It is anatomically impossible to give deep throat, or anal, for example. If it's too big as to be ridiculous, it makes the game funny and unimmersive!
I dont know about that it seems fine. Their reactions are hilarious and the art style makes it work. Im very immersered in this one. Have you seen being a diks guy? The community calls it the footlong lol.
