What, you mean "ole 3 balls". Well you have to take in to account the extra ball, and the power of "that" money shot. Your now dealing with a very powerful weapon, of possibly mass destruction, so keep it away from your face and especially your eyes, you may try to catch said explosion in your mouth but beware, it could knock out many of your teeth (As Obie say's, hopefully she got some teeth).
Best bet is take it internally, the crotch can take an amazing amount of force (believe me I have tried and tested the forces exurted during a very physically sexual experiance on a crotch, and it's pretty hard to break one)
so you should be ok, but still, be very careful. So if it does become to much, lube up some more, slow your rhythm and remember that you'll never be able to handle the power of the sherman...
