So, what I think is that the female sub might not have 'biologically orgasmed' - as in, the chemical and biological events following a 'proper orgasm' might not have happened, because scientifically speaking, those can truly only occur with contact to the sexual organ.
However, due to conditioning and strong sexual arousal, the sub might associate that feeling in her head with that of a biological orgasm. So, for all intents and purposes, it
is an orgasm to her.
If I ever see a man ejaculating on command, though, I will eat my words through and through.
