Most likely refers to a service provider PERFORMING DUTIES EVEN IF IT KILLS HER, becoming a MARTYR:「rotting infectious meat wrapped in tonguing mouth」「array of meat head with tense gasps of tonguing mouth」that may refer to fellating diseased penis regardless of personal risk, or suffocating while deep-throating, or both.
　「Season to die, death is ripe」or「death while rutting, death in estrus」refers to DYING WHILE PERFORMING ONE'S DUTY, or in other words, DYING ON THE JOB. The job in this case is every male's duty to copulate with a willing female while ovulating (or in the heat of estrus), and the strain or excitement literally kills the male animal, or kills the schwantz (left element of「meat hanging from bone[r]」) dying for a good cause, it may seem at the time:

　May refer to the genital 'vulva eye that winks' when the female of some species is in estrus, horses especially, signaling the desire and readiness to immediately copulate unabashedly by winking her vulva, complete with juicy puckering sounds (believe it, or not). It is the duty of any nearby male of the same or similar species to accommodate her desire, even unto martyrdom.
　「Winking the vulva is one of the signs a mare is in heat. Frequent urination, tail raising, squatting, and fence or wall pushing are also signs the mare is in heat. I have had mares that seemed uncomfortable being [ridden] and even acted colicky when in heat. You can have your vet [verify] to be sure this is what is going on. Mares vary a great deal in their behavior when in estrus (heat) from no signs at all to very pronounced signs. I hope this answers your question satisfactorily. Please let me know if I can be of further assistance.」

　Public displays of「meat arrayed in estrus with ovulation and willingness to copulate unabashedly」as HERALDING AN ANNOUNCEMENT (see the variant 徇) to all with ears to hear, among other appendages. Prancing about and loitering with one's vulva swollen, reddened, and exuding pheromone-laden fluids in order to entice males to battle one another for the chance to copulate with that meat:「one that gives a sign or indication of something to come. An official who formerly made proclamations and conveyed challenges at a tournament. To proclaim, especially with enthusiasm, announce or acclaim」　[　https://www.thefreedictionary.com/herald 2018-02-28　]
