M/M

Stories in which the erotic encounters and/or focus involves two men together (or wanting to be together).

Note on stories involving multiple sets of characters: Categories apply to the narrative at any given point. If a story involves Andy wanting to be with Bob, and Charlie wanting to be with Dave, it’s M/M, not M/M/M. If Andy and Bob hook up with Evan, then at that point it becomes M/M/M.

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.

His drug came from within. 5 parts 12k words Added Jun 2018 Updated 23 Nov 2019 47k views 4.7 stars (38 votes) No comments yet •Cock Growth•Huge Balls•Hyper Cock•Self-suck•Cum inflation•Cum Milking•Hyper Cum•Addiction•Immobility•Muscle Growth•Muscle/Strength•Belly Growth•Size Increase•First Time/Virgin•Nonconsensual change •M/M
