oh god this is intense i'm trembling and hot lololol i simply love the bara appeal it make...

What exactly is the appeal of a dick that literally no living human could either fuck or have?

well, people have different preferences and i like the emphasis on the masculine muscles, that works for me haha. it's the same as people liking small framed ukes and their cute small penises and big semes with their huge yaoi hands. bara is about hyperbole and this is just what the author went for. if you like realistic style then go for it, the big alien dick is not bothering me at all.
