Shackled To The Dungeon Wall - Bare Hands On Stretched Armpits And Ribs (Anime Bara, 20 Scenes)

In a torchlit stone dungeon cell, young muscular men are locked into heavy iron wrist and ankle shackles bolted straight into the wall. Arms hauled wide and high, chains pulled taut, buckles in full view - there is nowhere left to hide. Bare hands skitter and drill across stretched armpits and exposed ribs, fingertips visibly denting and squashing the skin, contact never breaking from the first frame to the last.

They twist, haul at the shackles and fight the whole fifteen seconds, laughing out loud open-mouthed the entire time. Sweat-shined skin, wet stone, firelight. 20 different scenes, every one a different man in the shackles - all of them willing participants who set the terms themselves.

2D anime bara animation. Hand-drawn style, no real people. No dialogue.
