So even as a NTR fetishist, This and the first one are just bad. Let me state that I will refer to Episodes 1&2 of Boku no Yayoi-san as episodes 1&2. I will refer to Episodes 1&2 of Boku no Yayoi-san 2 as episodes 3&4. Semi-Spoilers ahead, they don't tell much other than to help make a point. Story: I do not know where to start. Episodes 3&4 Boku no Yayoi-san completely contradict each other, for the first set of the OVAs it followed a storyline at least albeit the shittiest storyline ever. In episode 3 Hiro wins. Episode 4 shows that Hebizuka sort of wins.Episodes 3 & 4 could have been a what-if thing showing what would have happened had the story gone either way, but that is something for VNs not Hentai.

Art: It would be good if it was 2000-2005, but not now.

Sound: Only soundtrack existent is the Voices really.

Characters: Yayoi is a complete slut, and not even the good kind. Hebizuka is essentially the cast of Jersy Shore, but more of a douche bag than all them combined. Hiro is an oddity, he isn't exactly a Beta Male, but not exactly an Alpha Male.

Enjoyment: Look somewhere else, I only finished it to not leave it unfinished.

Overall: Possibly the worst Hentai I have ever seen in my entire life, I would probably prefer Yaoi to this, and Yaoi is just cringe disgusting to me.
