"the reader has no idea what transpired between Natsu and Akio between the school and Natsu's home. Akio could have been abducted or he also could have conspired with Natsu to help Yuki free himself of an imagined rivalry that was obviously detrimental to Yuki"...
Hats off to your imagination levelლ(´ڡ`ლ)
╮(￣▽￣)╭ ┗( T﹏T )┛
My very first memories were of observing people and asking myself, "Why do they do that?" So, it seemed only logical that in high school I began taking AP psychology classes. I continued into college and began focusing on sexual psychology because it fascinated me the most. I have interviewed tens of thousands of people for close to 1000 different essays, clinical experiments and papers in the last 35 years (both my own and those of others). My imagination is drawn from experiences, both personal and second hand from interviewees. You might be surprised at how often fact is much stranger than fiction.
I like your argument, and I think I would have enjoyed the story more if it didn't come across as kinda depressing.
Your could have beens are fine, but as long as the author didn't mention or didn't show it, it'd remain as an assumption. In the first place, if Akio was willing, Natsu wouldn't have to abduct him. Moreover, he wouldn't need to restrain him either. Your idea of bdsm is a bit confusing. Bdsm involves great trust to your partner. In the story, we saw the aniki telling the younger bro to stay away from the good for nothing Natsu. It means he generally knew that the guy was nothing but trouble. No, where's the trust there? This is not being biased but we all know that what happened is rape. Stop justifying rape. For goodness' sake.
Yes, this manga is erotic fiction, but not all work like that contains dubcon. And not accepting ideas doesn't mean readers are not ready or ill-prepared for the concepts as you mentioned. It's just some of us find things such as rape repulsive unlike some people who enjoy it. Oops.
So many comments making assumptions that Akio is an unwilling participant in the situation. Yet, the reader has no idea what transpired between Natsu and Akio between the school and Natsu's home. Akio could have been abducted or he also could have conspired with Natsu to help Yuki free himself of an imagined rivalry that was obviously detrimental to Yuki if it was causing him to steal answers before a test and potentially get himself expelled. The latter scenario seems far more believable since, at no time, did Akio show signs of anger, revulsion or even an attempt to struggle. In fact, he asks Yuki to, "Please put it in." It is the prevailing opinion that if a person is restrained and has pain inflicted upon them while engaged in sex, the act is automatically "rape". This biased view precludes the option of BDSM games. If many readers here witnessed the way in which I, and many of my friends, engage in sex, they would assume that we are being brutally "raped" and abused each and every time we have sex. Nothing, however, could be further from the truth, since we actively and consensually engage in BDSM games regularly. This is how we have sex. Thirty years ago, homosexuality; bisexuality; transgenderism were all viewed with the same distaste and revulsion that is expressed by readers here for situations they only assume are "rape". People "knew" these sexual preferences to be aberrations, disgusting and immoral. Imagine what we will "know" tomorrow.
This manga is erotic fiction. It is not a young adult novel or fairy tale. It is meant to arouse as much as it is meant to entertain. Thus, conflicts will not be resolved through typical, logical means. They will be resolved through sex. Sex is the entire point and purpose to erotic fiction, more so to explicit, or smut, erotic fiction. Why else would readers laugh at the idea of "yaoi logic"? It is a dismissal of the illogical means by which stories in this genre are propelled. The inability to recognize "yaoi logic" or the inability to separate fiction from reality is an indicator that the reader is ill-prepared for the concepts, themes and situations offered in the adult realm of erotic fiction and pornography. More time and thus, life experiences are required to prepare such readers.
