Non-yaoi friendly people often deride and sneer at the genre as being nothing more than porn. Those idiots don't know what they're talking about and there's no point in educating them.
But this? This is definitely just porn. This is probably what those types of people think yaoi is.
I know in Japan gay men do not like the word "bara" but Western fandom has come to use it for stories in which men with big, muscular bodies are interested in other big, beefy men.
This is, well, "bara". I don't like excessively muscular men. It looks bizarre when the man's tits are not just bigger than his head but projects well past what a woman's breasts looks like.
So, yes, this is also very fetish-filled. There's no plot, no deeper meaning. Just that the Main Character wants to get pregnant. He's an intersex individual who has male and female sexual organs. His male organs are incomplete; he does not have testicals. So he can't impregnate someone but he has a fully functioning, if VERY picky uterus. Thus, he can get pregnant.
MC is, for lack of a better term, a slut. He loves sex and will force other men who aren't interested in him into having sex with him. He's insatiable in bed.
I love big, beefy bottoms, too. But not mutant, deformed ones like this MC. If the porportions were more normal this would be so sexy but because of how grotesquely huge the MC is it's just...weird. It's not attractive to see.
Worse, the sex is drawn repetitively and weirdly. The genital positioning is just plain bizarre. It looks like his dick is growing out of his lower stomach, not the pubic region.
I know this art style is stylized but it shouldn't be THIS off-putting.
Anyway, I give it a 2 so far.
(Intersex people exist naturally in real life. Look up "intersex". It's what the "i" in lgbtqia stands for.)
