That's not cumming, that's extreme discomfort and pain, to the point that she's hitting the niggger to get him to back off, followed by a muscle spasm in the thighs because of the tension of the previous position vs after he's moved away, when she's still holding her legs up.
You can do the second half right now if you just hold your legs at an extreme angle for a while. It doesn't feel like anything, it's involuntary.
Why you stupid incels don't know this (no aerobic exercise for the kissless shutin) and keep pretending this means an orgasm is occurring (in the legs? lol), like you do the same when a girl intentionally pees and twitches (real orgasms are a thick and rather disgusting cream, not ejaculatory piss), it's all just shameful, a shameful display.
