here I am, browsing tvtropes, and I found necktie leash trope. There is only one yaoi in the examples, Under Grand hotel, and I've read that. (although I don't remember the actual scene). Any ideas?

PS: sorry for the tvtropes link. or not. muhahahahaha

if there is an option between "to do" and "not to do", I will always choose the latter.
