Whom ever the artist is (as you, Doom701 neglected to include a tag of the artist), there has to be something mentally wrong with them to sit down & create and then render such images.
Do not worry. Its another kind of art. It is not something to do in reality, but a fantasy. And it is historically correct, because most of impalment executions in history were anal. If someone do not want to see it, there is a warning and perhaps it is better to avoid it, if somone feels bad about it.
Dear cyberfish78, I hope you weren't born in 1978 because you are apparently completely new to the internet; and nothing in that image gallery is as barbarian as your use of emojis. I seriously presume you're a boomer wine aunt. What has led you to a hardcore porn site is beyond me.
