Hmmm… “Compulsory High Quality Sperm Implantation!? ~ Once You Start Ovulating You Get Fucked”… That title doesn’t sound like vanilla, does it?
But at least, I’ll give you that, it’s highly original.
Quotation: “Beeeeep! Ovulation confirmed! Please proceed to the nearest privileged genetics holder, according to the laws pertaining the selection of superior genes!“
Allright, to sum it up: we’re in a sort of vaguely fascist Japan, in which the elites are chosen for their genetic superiority, and the lower classes are obligated to accept to have sex with them. It’s not just that, everybody wears a collar monitoring emotional states, issuing recommendations, and checking when a girl starts ovulating. The moment a girl becomes fertile, she *must* accept a superior man’s sperm ¯\_(ツ)_/¯
In class, during sports, at home with the parents commenting their daughter moans loudly, the elite male MC has plenty of sex with the girl.
That could have been pure undiluted garbage, but the mangaka made good of that setup. The girl goes through several stages of acceptation, breaks up with her childhood friend (netorare, to me) as he didn’t find fast enough how to voice his feelings for her and find the words to display sympathy… and in the end, well, “that” was predictable, but “that” was still well delivered.
Graphically, the girl is on the plump side, loves sex, it’s not too censored, for the rest it’s a matter of tastes, see for yourselves! ^^
Thanks to Doujin-Moe for this one!
