You feel the arm in your hands, thin skin stretched across bulky muscle wrapped around fragile bone. Vessels pulse within, the warm streams of blood living within.
You begin to pull. The bone in the arm fractures, slightly, splinters embedding themselves into the surrounding flesh. Blood leaks, pooling within muscle, flooding the arm’s internal network of homeostasis, taking the system into irreparable imbalance.
And then it snaps, a satisfying crunch muted by the soundproofing qualities of meat. The flesh and skin hangs loose around the separated bone, calcium grinding into calcium, marrow flooded with internal bleeding.
The skin does not quite tear, but the spikes of broken bone pierce the skin, bringing subtle poolings of blood to the surface. Meat is torn out of the skin, horrifying needlework to turn the body inside out.
You release the broken limb, letting it dangle painfully from its still-functional shoulder. Whatever it was you wished to achieve, is now achieved.
