Muscle Growth

When your muscles are growing bigger. Especially relevant if the character doesn’t have much musculature to start with. This can involve muscles being grown conventionally (i.e., hard work at the gym), but usually there’s something more going on that gives the growth a push.

Compare Muscle, which can be just about having big muscles, and Size Growth, which involves getting bigger overall.

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. 17 parts 125k words (#14) Added Feb 2020 Updated 16 May 2020 28k views 4.9 stars (71 votes) •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•Pagan gods•Supernatural •M/M•M/M/M
