It’s not clear but I think you’re asking is it possible to ejaculate without direct stimulation while locked in your cage and performing cunnilingus? Yes it’s possible if you’re excited enough and, dare I say it, young enough. I’ve never experienced it myself though. It’s a generalisation but, for the most part, locked men find the act of being locked sexually exciting and sexually excited men ejaculate eventually. Whether it happens to an individual will depend on many factors but age, how recently you’ve ejaculated, how easily you ejaculate normally (i.e. with direct stimulation), how excited you are, what situation you’re in, how long you’ve been locked, will likely be some of the factors in play.
It is most certainly possible, and my lady loves it immensely! I must confess though, that I have cum just by pushing and rubbing myself against things while I'm kissing the loins of an appreciative lady. I was about seventeen when I learned how much of a turn on that can be, although the first time this happened it came on quickly and unexpectedly, leading to my embarrassment, to her delight, and to the great amusement of her friends. When I'm locked up I sometimes need some penile stimulation to ejaculate normally, so a free hand or a strong vibe held against my cage has me tipping over the edge. In the same situation and without any physical stimulation I have cum a couple of times, but mostly I just drip, and drip, and get more and more aroused until I can't "spurt" like normal and semen just flows freely. This is possibly a "ruined orgasm", a term I have recently come to learn. This leaves me incredibly aroused, incredibly sensitive, and obsessed with pleasuring my partner who is quite receptive to such attention. But to answer your question, yes it's definitely possible.

Your brain is your biggest sexual organ, absolutely possible (and happened to me many moons ago with a girlfriend of the time)
