Refreshing. As cruel and insensitive as this may sound, because there is little to no yaoi manga with a bystander pov - which is exactly what this manga portraits... The main character is not part of this pair, he is just someone who stumbled in this mess of relationship between his classman and the high school nurse sensei.
I really want to know what happened to sensei to be this cynical person. Also want to know how will develop from here on (will refrain seeing the raws for this one).

Hey, guys! You can see the raws for the whole story her (=・ω・=)e>>>> http://yaoi18.com/oboreru-triangle/

It's disturbing how rape can be treated as something light and pleasurable in a manga.
"Oh, but it was cute!" . IT'S RAPE! RAPE IS NEVER CUTE! THIS IS RIDICULOUS!

"Because is the yaoi world" makes this even more disturbing. I mean, most mangakas are women! If you see rape in hentai made by guys you just say "this is for guys". So guys and girls support rape in the fantasy world!
And then people question the world about all this raping happening everywhere. "Sick people!" Well... what do we read? What do we watch? What we are made to think is pleasurable?
Even if this is "just for fun", we should think why rape is "fun", "adorable", "hot". Even more... why is rape romantized? "The uke starts to feel good mid-way, so is not really rape" or "The uke falls in love with the seme-rapist, so is love".... (?!?!?!?!?!?!?!?!?!?!?!??????????)

I agree. Rape is never acceptable and it shouldn't be portrayed in a positive light, but the thing with yaoi is that it's about fantasies. In all genres of erotic fiction (not just yaoi), rape is used as a romantic plot device. I'm not saying it's ok, but rape is actually a common fantasy; it's about the "I'm so attracted to you that I can't resist" and the "dominance" appeal.
...serves you right, asshole.
