Think it depends on how long since they shot the last load of spunkI was taught by a former Master that a Black Man's sperm is extremely fertile and plentiful due to genetics through generations, because of the African heat He will produce copious amounts of strong fertile swimmers to ensure they reach the womb.
They are also well endowed to help deliver the sperm directly into the cervix.
Now this may or may not be true but I personally can feel a Black Man's cumblast deep inside and they do tend to get women pregnant rather easy so there may be something in it . . . .
