My wife loves to tease me like that. She will get me rock hard and stroke me a little and then tell me "get soft sissy". She does this over and over and all I usually get is a little precum that she loves to put on her finger for me to lick off. I love that precum. It always tastes so good! And every two or more weeks she does let me ejaculate and I get to eat my whole load.
I can imagine her talking while she does this, about how long she might make the sissy wait before that next cum, teasing and taunting, reminding her subject that the cage goes back on as soon as she's done.
