- Abyssus Abbey by Pen Darke [ ] Welcome to Abyssus Abbey… a place where monks study and summon demons in an attempt to prevent the Apocalypse. The demons are in the walls, listening to your words, your thoughts, your desires, and if you fall prey to any of the Twelve Temptations, you may find yourself changed in ways you may not have expected. The Abbey has always drawn and doomed those who seek power and knowledge, and if you’re lucky, you might find something else there: a change in your outlook, a surprising ability, a friend where no friend was expected, and even romance. But all pleasures come with a price, and sooner or later the devil will have his due. Come in. Join the damned. •Self-suck •Multicock •Straight to Gay •Muscle Growth •Muscle/Strength •Belly Growth •Transformation •Size Increase •Anthro/Scaly •Demons •Incubus/Succubus •Ogres •Satyrs •Witch/Warlock/Wizard •Fantasy Realm •Horror •Supernatural •Series Added Feb 2020 Updated May 2020 17 parts 124,798 words 22,303 views 4.9 stars (64 votes)
