Oyasumi Sex

There is no bond stronger than the one between siblings. Yui has been the center of her brother's sexual desires ever since they were children. But in recent years, something in their relationship has changed. The divorce of their parents has forced Akira to pay more attention to Yui's well-being, take care of her on a daily basis, and assume the paternal role in their family.

As the two grow older, Akira has taken notice of the physical changes in Yui—she is no longer the precious child he thought he knew. Unable to stop himself, he starts sneaking into her room at night, admiring his sister's body and pleasing himself to her. Akira becomes increasingly frustrated with the distance between them; but when Yui reveals that a friend from school has confessed to her, something snaps inside him.

No longer restricting himself to mere daydreams, he actively has intercourse with his sleeping sister. However, unbeknownst to Akira, Yui remains wide awake during these nightly visits; yet, for some reason, is unwilling to stop him.

Story: It is about siblings. If you are not comfortable with it, you may don't want to watch it.

Art: Art is good. After 2nd episode it will be better. Overall I liked it. Good Character designs, details, voices, sounds. It is more than enough.

Scenes: About scenes. Until the first sex scenes are so so. After first sex scene at the end of 1st episode, scenes start to improve. And one point. It is about having sex while sleeping. I mean the sister pretends she is sleeping until some point in the story.

Non-sense: There are no anal sexes, sick stuff, force sexing which is really good, ... but in my opinion when you love somebody you won't cum on her face(-_-). This parts look non sense to me, but hey! It is super safe to watch.

I liked it so much. First episode is kind of below average, but it keeps improving. I recommend watching it.

NOTE: For more good hentai recommendation take a look at my anime list and tags.

Story :
I very like this anime story. I've watched it many times. When i watch this anime, i feel nostalgic because I've experienced something like that in my life. Not 100% similar, maybe only 70% similar with my personal stiry. .That's why i very like this anime.

Art:
This anime art is great for a hentai anime. the animation movement is also not stiff, the point of view when doing the "nice thing" is also quite good.

Sound:
The anime backsound is really good. The ending song is good too, this is probably the first hentai anime song i've ever heard until end when i watch the ... hentai.

Character:
I really like this anime female character, to the point that my profile uses her name also her photo. I also really like the main character. He is quite representative of me. It makes me really feel this anime. The development of their relationship between the two is also very interesting. At first it was the protagonist who started it and the female protagonist just kept quiet and pretended to be unconscious and ended up becoming a relationship that everyone expected.

Enjoyment:
I very enjoy this anime. While watching this anime I felt I was in the anime. Maybe because I've experienced the same thing. For people who like the incest genre, you will definitely enjoy this anime

Overall:
This is masterpiece and my favorite anime all of time

How is this even fappable material????

When I chose to watch this, I'm already aware that it's hentai. The name of the show is Oyasumi Sex, which literally means Goodnight Sex. I thought I will be watching some regular normal sex every night with MC male joining his girlfriend to bed while doing the Nightly-Tango. But it turns out, its just "Let me Grape my sister every night."

You see the problem here, it was like I was watching something illegal. There's three things which makes me thinks this show is F'd up!

First, they ARE siblings. Not step- Not foster sibling- Not Half- (now that I think ... about it, that's also worse) not even through a far distant blood. They ARE siblings, FLESH AND BLOOD. They both literally came out by the same Vajayjay.

Second, the age gap, imagine how old they were in here. They may not reveal it. But it's obviously CRYSTAL CLEAR, that they're in school.

And the third and final thing, the MC male has admitted in two episodes. That he literally GRAPES his sister every night. (His lucky his sister liked it. But that in itself is still wrong in so many ways).

At the first episode, he narrates how he has to be the father figure to his sister because their father died or whatever. But as they grew older, he notices how his sister is changing (obviously her body). And he (with his devilry mind) admits that something changed in him that day. And that day was the day where he GRAPES his sister every night.

We each get to see the side of the brother and his sister. But base on my perspective, brother GRAPES sister every night which in time sister grows to like it. I don't know about that but that looks to me he was able to make his sister think this is good, and that's because his sister likes him. Look how freak up is that....

The animation is MID too!! It became a chore to watch them freak, I couldn't help but skip every 5s on how boring the SMEXY is...

It's torture I tell you! It's torture!!!
