Get the suspicious armmug. When one of your limbs is ripped painfully from your body and a group of 12 men, one by one, stick their dicks into the bleeding muscles of your torn off limb and fill it with cum. Eventually the limb will lose blood and discolour but will still be rock solid from the dried cum.
