A fox anthro, Arlo, loves nothing more than delving underground to see what secrets he may uncover there. Of course, he can only do so much as an anthro - but he's discovered a secret no one else knows of in an old slate mine.
Down and down and down... Oh, Arlo knows the way and is not worried at all, not all alone in the darkness. For he has a very close friend down there who takes care of him, even if the tentacle monster lives most of the time in a flooded cavern.
Together, they've learned to explore each other's bodies, lusting and enjoying a close presence, need swelling through to join them forevermore. There are few limits they will not explore, but the passion of a tentacle monster is not to be denied when it thrums through a willing body so very easily...
Author's note: this story contains consensual sex between anthropomorphic characters (fox anthro and tentacle monster). As in all my work, all characters are aged eighteen or older and clearly written as such.
