We know that you can probably consume your own piss at least once but, what about your own cum? You're 2 days lost without water, your semen is wasted in your body, can you fap and swallow your own nut to prolong your existence?

MOOOODDDSSSSSS

I once read an erotic story about a dystopian future where two girls hid from the government, and to survive they needed to eat cum from all the men in the apartment building. Also they had to take it up the ass because they couldn't risk pregnancy or suck that many dicks.
