Holy shit, wall of kanji! Good luck to those who try to translate this big boy. Although, it seems like a tasty drama, with that half-dead komarisa and all.
In short, Winter approaches, the koyukkuri is dying, and the Marisa, who accepts her incoming end ("I have already taken it easy") begs a Femanon to please let the baby take it easy.
Marisa knows that Femanon is lonely. After much begging and poking at the own Femanon's own misery, she accepts.

Non shitty Marisa detected. She has trained her daughter well, she claims (food and where not to empty her guts, etc). Interesting.
Also after looking at the story it seems like summary above is correct, but additionally the yukkuri there was a typical abandoned pet that broke the no refresh rule and apparently even after successfully begging an anon to take its child as a pet the anon discovers that the koyukkuri is already dead.
