Experience Tumblr like never before
We don't know a lot about how Bill's species reproduces so breeding kink could be really confusing for all parties involves. Exhibit A: Bill w/ partner that ids as female and has a uterus. He attempts dirty talk along the lines of "If we keep this up I'm gonna make you a daddy!" and they're like wait what
HAHAHAHA NO STOP, THATS SO FUNNY. Bill drops that line and the reader just stops what they’re doing for a second and is like, “..what?” In all seriousness though, you’re so right, it would be so confusing.
Honestly, I don’t imagine Bill’s geometrical species reproduce even CLOSE to how humans do. That’s one of the reasons I don’t think a breeding kink would be very probable, but I guess if we’re just having fun, maybe that’s what makes him interested in the whole process of like “human procreation.” Which might lead him to get a few facts wrong!
