Yes, this is about two girls, even though you see a man in all three pictures, because you see, the male is very important in what is going to happen to the two females, in fact he's crucial to it! See, the male is going to anally fuck the one female up the ass, which by itself is interesting to watch, for sure. But, what happens next is the neat part. The cum that the man has deposited in the girl's ass will then be transferred to the other girl's waiting mouth. Now, that's a cool sperm swap if ever I saw one!
