Fantastic hentai with plot. You will end up watching the whole thing. In general, most people watch hentai to fap/look for fap scenes and then they're done. How many people actually continue because they want to see the story, and is what you're seeing more than just a stage show for sex? That is probably a good way to define if a hentai has plot. A hentai is definitely good hentai when you want/able to fap to it, but it is the sex scene that hooks you in. When I see a hentai with plot, I desire to hold any fap intentions in just tosee the story play out. I go back and pick a part to fap after I finished watching. This hentai is exactly that hentai with plot. It got an excellent, interesting, and really developed plot. All the girls get to have sex through plot development not because its her turn to have sex. The characters are honest which I like, acting human with great backstories. Right off the bat, I'm going to say this hentai is a hidden gem. It has a lot of elements, ROMANCE, consensual, bondage, stun gun, rape, mild feeling of NTR, teens, oniichan, all incorporated very well. The main character Ryuichi is a much better guy than the average loser. Hiromi got a sexy body, and Wakaba is a cute imouto. The flashbacks Ryuichi gets really presents much buildup and suspense. Don't be intimidated by the synopsis that someone dies. It does happen, but it's not painful to watch and contributes to the suspense/peril of the current situation/story. The ending is really suspenseful, adds a lot of emotions, and is a good end/make sure to watch past credits of episode 3. To describe my experience with this hentai, thumbs up it's my favorite.
