In the dimly lit dungeon, The Master, an expert in gay fisting, commands his boys to line up. The first, a lithe compression boy, bends over, exposing his tight, hairless hole. The Master, with a confident smirk, applies lube and slowly inserts a finger, then another, stretching the boy's ass. The boy gasps, but the Master's firm grip keeps him in place. He adds a third, then a fourth finger, twisting and turning, exploring every inch. The boy moans, his cock hard and leaking. The Master pulls out, leaving the boy panting, before moving on to his next eager student.
