Another idea for the bloatflys... IIRC there's a quest in Diamond City to gather a bloatfly gland for the chemist lady, a 'field trip' science experiment. So a quest where now you return later, after that one when she calls you up on the radio asking for help in her lab. You arrive and she says she has another thing that you'll be paid for this time for a different science experiment, or a different collection for more bloatflies anyway. After you agree, she has you strip down and lay on a table, so that she can apply some bloatfly 'pheromones' to you. Of course, the table straps you down and while you struggle, the somewhat ditzy scientist hums and goes around and then ring gags you because you'll upset the bloatfly she has from the gland you brought her. And then you're stuffed with bloatfly eggs in your mouth, womb and ass, before passing out after the rape. When you come to, you're naked, bloated (heh), are wearing a tracking collar and have an eartag with a number on it. You seem to be in some kind of vault with a lot of bloatflies, which a nearby terminal helpfully tells you are your own children. You've been here for a week, sedated as you were raped, bred, gave brith, and then repeated several times. You have some minor mutations. At this point, you can try to escape and burn out the vault, killing all of your children and probably being raped a couple times along the way, or you can embrace your breeder status and escape and bring back a female with minimal vault damage, and the scientist will find you, call you a dirty slut experiment (she only refers to you as your eartag number, with derogatory comments in an absent minded way), and let you come and go as you please with you capturing new victims for more bloatflies. She never does explain WHY she needs women to be raped by bloatflies, or what the bloatflies are for.
