She made me wonder: if there’s such a thing as a “small penis humiliation”, is there a “big penis humiliation”, too?

In any event, there’s certainly a “small cage humiliation.”

Of course there is!
‘Oh darling, you know I love your big cock but it’s just too big for my tight little pussy, and there’s no way I’m letting you near my ass again. So I have got this cage to help you stay, controlled. Your tongue feels better anyway.’
