For anyone who missed it, review of the first 50 chapters: https://chyoa.com/chapter/My-Roommate-Is-Possessed-By-A-Brain-Slug,-by-Zeebop.1868223 With a reply that reveals some of the secret What Might Have Beens behind MRIPBABS.
Sorry for the delay on today's chapter, I swore I posted it this morning before work, but apparently I did not.
It's really weird to consider that aside from the brief dream-sequences, this is probably my most aggressively straightforward and restrained story in terms of focusing on plot, relationships, and normal sex.
The weirdness is here very much tied to the plot. You have certainly done well keeping the plot moving, not too fast but constantly forward.
