It also depends on the girl. I will usually only cum in their pussies if they are on the pill. Then, there are others who beg you to cum in their mouth, so for them I will usually pull out of their pussies at the last moment and then shoot in their mouths. And for the ass, well I would say only 10% of mine actually take it up the ass, so with them it usually BJ, pussy, and then finishing off with doing their asses, and even for those girls, I don't always do them up the ass each time.
