I still think this manga makes no sense...

pussy and bussy r two different things ig

Yeah but oral allowed him to turn back to a man... Pretty sure that would make any hole viable lol

I think the first time they had sex as guys Rui wore a condom no idea why he did- but that’s probably why Shion turned into a girl again lol

Did they???? If that's true then it makes more sense, but how would Shion not know it's not like you can sneak one on. Lol

If you go back to the chapter when they first fucked as guys you can see that Rui opened one soo? i’m just assuming he put it on just because why would it be shown pLUS ripped open if he’s not using it yknow?

Just went back and re read that part he definitely used one then yeah that's why he turned back into a girl then. Why does Shion think it won't work then is they aren't using one now they he should stay a guy just fine it's all good. (=・ω・=)
