The point is what
@Kiriha said.
This is the
fantasyof being dominated by a handsome assertive male, not that different from the male counterpart of being dominated by a "thicc tiddy oneesan" or such.
This is
not a slice of life realistic depiction of sex, nor is it advertised as such.
Conveniently finding a handsome yakuza injured and in need of help just as she needed a yakuza reference? A cat conveniently leading her to said character?
You cannot be willing to suspend disbelief when it doesn't offend you, then
demand realism when it does. This author's works never were realistic, and depict such fantasies often.
