#it is meant to make *just* enough sense to bypass my brain going BUTT BABIES AAAAAGHHH

[user-needs-new-hyperfixation]

Extremely rudimentary, blurry, and completely without scale concept art for Omega Butthole that does not Bother Me:

A. Vestibule. Becomes elastic like a vagina during heats and labour, and self-lubricates during heats. Generally it operates like a normal butthole (ie lube recommended for recreational activities).

B. Babychute

C. Poopchute

Dotted line 1: some sort of sphincter or flap that remains sealed except during heats, menstruation, and labour

Dotted line 2: some sort of sphincter or flap that remains sealed during heats, menstruation, and labour

In the days leading up to a heat, a period, or a birth the omega's metabolism changes. They largely lose their appetites and what food they do consume is used by the body at almost 100% efficiency, so that Not Pooping for several days is Fine.

Heat cycles are approximately quarterly, so it's not like omegas are caught in a four week cycle where for two of those weeks they don't eat.

These omegas also have a fully functional and fertile dick and balls, making them prized for their ability to provide heirs every which way. While I suppose that makes them some kind of fantasy intersex, I wanted to emphasize the Fantasy Anatomy a bit because sometimes intersex omegas in fic are just like??? Is the A/B/O setup actually contributing anything here? Okay they're intersex! that's cool! but what makes them an omega? And my answer to that question is apparently: railroad switch in the butt.
