Dang she was a virgin and took that monster like it was nothing... Im so disappointed. B...

I feel like it must be female especially after that vasectomy comment most male authors wouldn't care about it quite opposite

I'm so happy that I found a kindred soul who guesses the author too. This time, I think its a female too. Because if the author was a guy, the FML would be screaming oppa, whereas its the 2 guys who keeps on saying oppa will do this, oppa will do that.

Strongly agreeing

vaginas are miracle workers

At the start i though male because she's a "blushing virgin" then as you said the vasectomy, the last scene where he carried her to the bathroom intuitively felt like a woman wrote it. But i'm not 100% sure, could be a guy that has actually studied Josei. I need more chapters to know.

Also the oraeboni/oppa kink feels like it comes from male fantasy smut so idk

I feel like the ratio would’ve been different if a male wrote it? Two girls to one guy?

This is josei(made for women) and plenty of male authors write josei these days. It's just that you can usually tell.

You forgot the most important part
If the author was male her boobs would be Z cup and she'll be asking them if they think it's too big instead.

uh... did no one see how during the oral sex, the girl had no teeth? That is a man's fantasy for sure. ><

dentures ig

.

I feel like the author is a woman. Not because of the vasectomy comment (although that and the other guy wearing a comdom does make it less likely a guy worte this) but because the way both guys are dominant but caring. In my experience male authors rarely take the female perspective into consideration. The girl usually feels like a fuck doll when men write smut and im not getting that feeling here

but male authors can attempt to clumsily take into account the female perspective when they write josei

True but I've only ever seen a small handful that have gone past clumsy and actually get it right.
