Especially guys like this who come back-to-back-to-back with no more than a few seconds in between...how the fucking hell do they manage that? Is it a true multiple orgasm, or have they somehow separated the spurting of cum from the actual orgasm so they can keep going? Is it some freakish talent or a trained skill?
Inquiring (and dirty) minds wanna know.
In the case of that video, it's probably a trained skill. No, he's not doing a true multiple-orgasm, he's brought himself to the point of barely needing to cum and then letting it leak out a little at a time, rather than stroking himself intensely to try and shoot the whole load all at once. The key is not to stroke off (or otherwise be stimulated) immediately prior to, during, and in the seconds after the cumshot.
It's a great trick because you can cum over and over and still stay hard. I keep waiting for a real pro to do it in a series and make it his trademark -- he could really fuck the daylights out of a girl and give her several facials and still pound her some more and have the whole "I am a fucking god who cannot die" swagger thing going for him.
There's also a weaker variant of it you sometimes see, which I'll call the "misfire", which often happens when the girl does a bad job of jerking him off at the end, and he's left with the feeling he's not done, so he jerks himself off to a second pop. But again, it's not a multiple-orgasm thing... it's just that she fucked up getting him off and he had to finish it himself.
What I love is when the guy has the presence of mind to shoot on her face or tits, and then manages start fucking her again almost immediately after, with the cum still on her as she's being pounded again.
