Apart from all the genital talk between Nayuta and Miyako, episode 2 is where our main characters start to show us their work process and we get to dive into the genius novelist, Nayuta. Well, apparently Nayuta cannot write without being completely nude! So in episode 2, we join Nayuta completely naked as she works. Of course, we can’t just talk nudity, can we? This is also the same episode that Miyako joins Nayuta to find out more about how she works. Except, Nayuta has one little request.

To get the right image in her mind, Nayuta requests to grope Miyako’s boobs because it’s for research, right? Miyako hesitantly agrees and then, with an “itadakimasu,” Nayuta dives in and reaches for Miyako’s breasts. While the scene cuts off after that, this episode really serves as a glimpse of the time of fan service that is to come in Imouto Sae Ireba Ii.

Oh, it just gets better and better with each episode. Episode 3 is where Nayuta, Miyako, and Itsuki go on a trip to Okinawa. While at dinner, Nayuta and Itsuki have an interesting exchange where she tries to ask Itsuki for alcohol and he denies her request because she is underaged (18). As such, they have this back and forth where Nayuta vehemently requests to have sex with Itsuki, and he, pretending to be as deaf as an old man, keeps mishearing the words she says and misdirecting the conversation. This ultimately ends in Itsuki giving Nayuta a hardboiled egg to eat when she requests to drink alcohol again.

Are we boring you? Well, sit tight. This is the moment when we get to see Nayuta eating an egg and she doesn’t just eat that egg, she really goes at it. In this scene, Nayuta sucks off the egg in an attempt to mimic fellatio with all the saliva and noises necessary to catch the interest of any man. Watch as she sucks this egg off and exclaims about having Itsuki’s balls in her face right at the beginning of this episode!

Nayuta knows no bounds and episode 3 shows this when, uninhibited, Nayuta undresses and jumps into the ocean when the gang are at the beach. Of course, Itsuki’s there but lucky bastard just averts his gaze and cannot look at the glory that is Nayuta. Oh Itsuki, how you disappoint us so. At first, Nayuta just floats in the wonder in all her glory but then she decides to jump and splash about like the carefree maiden she is.

Well, let’s not stop there. Despite some trepidation, Miyako strips down and jumps right in! Oh yes, a lovely and naked Miyako alongside the glorious Nayuta, splashing water at each other and throwing caution to the wind. Nayuta even stops to make a comment about Miyako’s body which allows the camera time to pan Miyako in her nakedness. How does Itsuki just sit back and look away, we wonder. The rest of the scene is rather censored by the splashing of the water, but we leave that to your imagination to enjoy.

If any episode could win in Imouto Sae Ireba Ii. for being the most ecchi, it’d be episode 7. This is the episode in which Itsuki and the gang decide to play a story telling RPG where they make up the story as they go. Here, we have Itsuki with many sisters and he’s also playing as a woman, so the ecchiness isn’t muddled by any men, you know?

Starting from the public acts of indency that helps power Nayuta’s power in the town square to fighting the tentacle monster completely nude, there is no end to the ecchi scenes in this episode. Heck, with Itsuki playing as a a woman, it makes it just that much greater. Watch Nayuta power up by straight up molesting Nayuta on the streets of the kingdom or watch the entire gang play in the lake completely naked before being nabbed by a tentacle monster. If you want fan service, episode 7 is the episode where it gets down.

Ending off our list of the top 5 Imouto Sae Ireba Ii. ecchi scenes is episode 9, where we have Kaiko arguing in favor of the beauty of panties. She argues with Itsuki to show him how powerful panties can be over straight nudity. Kaiko just refuses to back down from this belief as the panties can have their own allure that some people may not think about. However, the person who requires extensive convincing is Nayuta.

As Nayuta is about to rip off Kaiko’s rose panties (symbolism at its finest) to shower Kaiko how great being nude is, Kaiko decides to fight back and this fight becomes a full on grope fest. Kaiko is groping at full force and Nayuta is making all sorts of indecent noises that would get your blood boiling. The scenes are a bit censored at this point and you get to enjoy seeing the shadows making their move, but there’s more than enough left to fuel your imagination. Not to mention that Kaiko decides to bring Miyako into the mix right before the scene cuts off. I think nudity won the battle?
