Agreed! I'm super confused, and the storyline is pretty much nonexistent. The sex scenes are sexy, but the urethra sex is just downright nasty and unrealistic (like I'm pretty sure you can't do that in real life)
Yeah, it's part of an anthology with three stories. This is actually ch. 3 out of 5 chapters of the story, "Ore wa Kawaii Otouto to". I have no idea if the rest has been scanlated.
One-shot "Pero Pero-chan" is also part of this anthology.
It's totally a thing. Look up urethral sounding.
If it is a real thing, then no thanks! That sounds horrifying Σ(っ°Д °;)っ
I think before you read a manga, especially yaoi manga it's advisable to read the tags first. It's a bit misplaced to complain about the lack of plot when the manga is tagged with adult, smut, incest and urethra play. Of course there are smut with plot but usually smut means pwp (porn without plot/plot what plot). It's like complaining about the lack of romance in a action shonen manga.
I don't even know where to begin. It kind of just drops you into the story with little to no back story other than these are brothers who are fucking and who happen to be teachers. It reads like a chapter two instead of a oneshot. Their urethra play is the stuff of emergency room nightmares.
