I just wonder if we're going to be top, bottom, or will be able to choose?
as much as I'd like asterion to top, I doubt a human could take him, if the MC is chest height to asterion, I'd only assume his dick would be as thick as a person's forearm. that being said, much like height of people had increased over history same is probably the same with penis sizes (even if he's a Minotaur, he's still thousands of years old, it might effect some stuff)
