If you're going to go through the effort of writing domination MxF, might as well make the 'man character' some 9'11" baddass ogre of a man with
muscles for days.
Oh Re: Monster already does that? And... *gasps* he
eats people?!
Disclaimer: I swear I do not have a thing for 'vore', but have you seen his teeth? That mighty jaw?! THE NECK MUSCLES!?
Being dominated by some scrawny guy? I can't even see the fun in that. Where's the barely-restrained/unrestrained overwhelming mass and power that could break you? Where's the stability and security and safety all inherent in that massive built up and healthy frame?! What is there even *to* like?
Which is an entirely different story to being dominated by a girl
Most any size'll do, cuz the size isn't the core draw anymore. But that only works if you're also a girl... otherwise you'd usually have to be 'letting it happen', which isn't the same as 'dominating' anymore at all.
