My only explanation is this.
Sperms are ravenous by nature, they can actually eat one another to survive, so this might be why they nibble on the egg.
Thing is though, how the hell does she feel it?
Well, you see, the existence of either god or this image excludes the other, because a benevolent omnipotent being would not, COULD not, allow this atrocity to thrive in his creation. Seeing as this image does in fact exist, we can conclude that we live in a godless world, and that we all deserve to die, for a species that brought into existence the sheer horror of what we have just witnessed should not be granted permission to coexist with any form of life or sentience.
