So last night I played with a boy who's kind of stubborn. Early in a session, I usually humiliate the boy by making him say "I'm a pussyboy", but this boy was refusing to say it. So I said, "Ok, boy. Your safeword is 'I'm a pussyboy'. You want me to stop, you need to say that." As the scene developed, I was torturing him--working his tits, slapping his cock, paddling his ass and thighs, working them with a toothbrush--and I took him up to his limits, forcing him to use the safeword. By the end of the night, as his endurance was wearing it down, he was using it faster and faster, which of course increased the humiliation of saying a phrase he was reluctant to say. But it got me thinking. I was intentionally taking to his limits with pain and forcing him to use his safeword. He certainly understood what I was doing, so I suspect he wasn't going to his absolute limit, but I was repeatedly being rough enough that he used the safeword, because making him use the safeword was part of the game. And I was of course being careful to not do anything unsafe. Normally a safeword is an escape hatch, not a piece of the game. What do people think? Is it safe and reasonable to use a safeword this way?
