I think only select girls can do it, or have learned to release the squirt hatch.
Cause there is like three videos i can think of where I've seen the girl blow her load. And since pornstars are professional fuckers you think they could all do it.
No, I've never made a girl do it, but after learning it's mostly urine I don't know if i want to.
Edit:
After reading that guys story it seems pretty bad ass, I might have to give it a try,
