Oh, no, DamDudes, there is such a thing as senior citezen porn. I think. I meant the book itself is just messed up. As are the reviews and the others in the "also by the same other", particularly Taken By The T-Rex.
Then again, as this dinopornus has shown us, there is a porn for everything. One is reminded of a name I recall on here years ago, IBetTheresFlumpPorn. There probably is.
