can you explain more? what exactly is fiber pills?
They're pills you take regularly so that your pooping is more regular and your digestive tract is cleaner. For instance, Pure For Men is popular with gay men. (amazon link below). Basically, bottoms have two ways to deal with the realities of bottoming. Not eating a few hours before the sex and douching for good measure (that's a whole other process), or taking fiber pills. So when I saw Aki eating, I started rolling my eyes. But they had sex within an hour of eating, so it probably would have been ok.

Those are things ya just don’t think about ya know?
wait, having anal sex affects your pooping schedule???
... shit I just knew that there were stuffs like these and I've been bottoming for my bf for 3 years now (but I doubt my country even sells these, I usually only find condoms in stores but not lubes). I usually only clean it right before getting it on. Thanks for the info, guess I can start using this as well.
learn somethin new again thanks
As a gay man, I immediately eye rolled when I saw Aki and Ueta eating. I could tell they'd be having sex later on, so I was like, "They better do it quick." I think they did it quick enough to not make it a total immersion breaker, and I'm now building the headcanon that Aki takes fiber pills, but this is just one of the little realities of gay love/life that non-gay mangaka miss when creating these stories.
