Incest between siblings is the most popular taboo topic in hentai anime. Since I know some of you want a guilt-free fap, let’s try a less dangerous version of the sister complex. Who’s up for some step-sibling sex?!
What if your mother marries the father of your crush? What if your father’s new wife arrives with her smoking hot daughter? You’d be doomed either way… Unless, of course, you’re a hentai anime character! I’ll show you some of the best hentai anime about stepsiblings fucking each other with no regrets in this list. And I don’t blame them; sneaking a fuck here and there isn’t strange if you’re not blood related…
Ane Jiru The Animation: Shirakawa Sanshimai ni Omakase · Episode 1+
Let’s start with Ane Jiru, a straightforward hentai anime. Yuu inherits a cursed bottle that he must fill with pussy juice to avoid bad luck. It’s one of the most ridiculous premises I’ve ever heard. It’s also a great opportunity for him to get inside his three stepsisters!
Despite their ignorance of the curse, the girls give little resistance to Yuu’s sexual advances. Under the influence of the bottle, Kyouko is raped in her sleep and Ryouko is fingered on a crowded bus, but neither is bothered. Anzu, like any other tsundere, plays hard to get but eventually succumbs to Yuu’s morning wood.
Overall, Ane Jiru’s plot is secondary, so your attention is drawn solely to the sex scenes. With three stepsisters with very different personalities, I’m sure you’ll like at least one of them. Oh, and before you ask, Ane Jiru concludes with a quartet!
Kyonyuu Kazoku Saimin
Despite its cliché premise—a guy hypnotising women—Kyonyuu Kazoku Saimin is a modern classic packed with kinky sex scenes. Yuuichi is about to realise his dream thanks to a mysterious laser pointer. With his stepmother and two stepsisters, he will finally have a family! But things aren’t as wholesome as they appear…
Yuuichi moves on to Natsuki, the eldest of the Mamiya sisters, after having his way with his stepmother. He makes Natsuki flash her boobs with his laser pointer before licking her sweaty armpits and fingering her through her panties. Later, Yuuichi hypnotises the more gullible Akiha and convinces her to ride his dick.
The scenes with Natsuki and Akiha are shorter than those with their mother, but Kyonyuu Kazoku Saimin is still a fun fap. I highly recommend Yuuichi and the girls’ foursome, with Akiha recording her sister’s first time and Mifuyu masturbating to her stepson ramming her daughter from behind. Finally, a lengthy scene with Yuuichi and one of his stepsisters, as well as a satisfying conclusion to this one-episode OVA!
Jitaku Keibiin · Episode 1+
Tsunetaka, a veteran home security officer with military experience, is suspicious of his new stepmother. Tsunetaka uses hidden cameras and microphones to blackmail the woman and her two daughters into leaving once and for all, accusing her of being a gold digger. Fortunately for him, all three girls have something to conceal…
Tsunetaka’s stepsisters are the focus of the first two episodes of Jitaku Keibiin. Sayaka is caught on camera being raped by her swimming coach in Episode 1, which could easily ruin her reputation. Tsunetaka discovers Yuki is a lesbian in Episode 2 and films her having sex with one of her classmates.
Despite the fact that the setting is similar to Kyonyuu Kazoku Saimin, Jitaku Keibiin gives each girl her own episode. Also, Jitaku Keiibin is rather depressing and focuses on voyeurism and blackmail, with Sayaka as the submissive stepsister and Yuki as the more defiant.
Kutsujoku · Episode 1+
Souichi uses his mind power to persuade the most beautiful girls and teachers at school, including his mean stepsister Aika, to have sex with him. Souichi first trained his stepsister’s body with sex toys before finally using his dick. Aika was soon begging to be his sex slave, always ready to please him, even at school.
It would be incorrect to say Kutsujoku genuinely cares about Aika. To be honest, she appears to be a plot device to provide context for Souichi’s plans. Nonetheless, her scenes are long and varied enough to make you fap. In Episode 2, for example, she is seen sharing Souichi’s dick with the other harem girls. Kutsujoku has a really cute stepsister if you watch hentai anime for the sex rather than the story.
Kazoku: Haha to Shimai no Kyousei · Episode 1+
Itsuki decides to punish his father after discovering he is cheating on his stepmother. How? By allowing himself to finally entice these women to his dick. Sounds familiar: a man, an absent father, a stepmother, and two sexy stepsisters. We can now confirm that is the standard recipe for a harem hentai anime about a guy fucking his new family.
Itsuki’s elder stepsister, Nagisa, is the first to taste—literally—his dick. Unfortunately, Itsuki does not pursue her again until Episode 3, while riding the crowded train to school. Itsuki, being the hero he is, saves his stepsister from a molester…and all heroes deserve a reward. So he starts rubbing his dick against Nagisa’s thighs while touching her boobs and pussy. I know it’s ironic, but that’s Itsuki’s way of claiming his territory.
Fuuka, the youngest, appears only briefly in Episode 3 and for half of Episode 4. But it’s worth the wait. Itsuki fucks Fuuka in the same way he fucked Nagisa in the girls’ changing room. He rapes Fuuka in the locker room this time, right next to her unaware classmates. If girls in swimsuits or doing butt stuff make you uncomfortable, you’ll enjoy this scene!
Fault!! · Episode 1+
Fault!! perfectly depicts a stepsibling relationship, and we soon discover how much of a pervert Mio is. The best thing about this hentai anime is that there is little to no hesitation between the two, and there is no hidden agenda as to why they choose to fight.
Despite the fact that the protagonist fucks other girls as well, Fault!! Shuuichi, his tennis club partner Ai, and his naughty stepsister Mio, who is also a member of the tennis club, form a love triangle. There are plenty of steamy scenes starring Mio to go around in its three episodes, including a
Mio rides her stepbrother while Ai masturbates to them in Episode 2. There’s even a double blowjob!
Unlike some of the other hentai anime on this list, Fault!! is both indecent and entertaining. You won’t feel bad about Shuuichi ripping off his stepsister!
My Imouto: Koakuma na A-Cup · Episode 1+
Miyu is so self-conscious about her small tits that she orders various items online in order to conceal her flat chest or make her pair appear larger. However, for some reason, she uses his brother’s information, and the package is delivered to Mitsuru. Mitsuru, surprised, says that small tits are cuter and that his sister shouldn’t worry, not realising what those words would awaken in Miyu. It’s time for her to rub her nipples and masturbate to her brother, the only guy who compliments her petite chest!
Although the animation isn’t perfect, the banter and teasing between Miyu and Mitsuru is relatable to anyone who isn’t an only child. That is both the best and worst aspect of My Imouto: Koakuma na A-Cup, a perfect combination of things escalating for no reason and a believable relationship between stepsiblings. Things are sweet and even romantic in Episode 1, with a long scene of Miyu fingering herself and the climax of Mitsuru penetrating his stepsister. Episode 2 takes a darker turn, with Miyu and Mitsuru fighting in the schoolyard or the boy tying his sister to the bed and forcing her into anal while crossdressing. If that’s too much for you, just Episode 1 will suffice to enjoy a lovely story about stepsiblings comforting themselves and having their first sex.
Kakushi Dere · Episode 2
Misaki comes home early one day, frustrated that her stepbrother only has eyes for other girls at school, and comforts herself by smelling his sweater. One thing leads to another, and she finds herself masturbating at the prospect of Makoto fucking her in class, but things get strange when he discovers her half-naked in his own bed. Makoto confronts her stepsister about the situation, not expecting her to quickly confess that she was masturbating because she loves him. Enough to make Makoto go crazy and fuck her like there’s no tomorrow!
If you like girls with big boobs and long ponytails, Misaki is the girl for you. It’s so cute how she licks and kisses Makoto’s glans before giving him a blowjob! Makoto and Misaki’s attempts to explain why they were constantly clashing add some realism to their relationship, which I like because it makes me feel like I’m watching two stepsiblings who couldn’t handle their inappropriate feelings, rather than a generic hentai anime couple. For what it’s worth, Kakushi Dere’s second episode is entertaining, especially if you like lighthearted romance hentai anime.
Shoujo × Shoujo × Shoujo The Animation
Are you not interested in one-on-one sex? Are you sick of positive hentai anime? Okay, then here’s something a little darker for you. What about a guy who despises his father and is on a mission to save his stepsisters from this sadistic monster before he turns them into his new fuck toys?
If we disregard Kengo’s conflict with his father, Shoujo Shoujo Shoujo is the story of a guy fucking his twenty loli stepsisters in a big orgy in a grotto. And, yes, all the girls are in love with him, which makes sense given that Kengo is the only guy in their lives. Still, Kengo’s father is crucial to the plot because he is the one who brings the most sinister fetishes to the table, such as rape, bondage, and exhibitionism, to name a few.
Although it was released in 2012 and the art is now dated, Shoujo Shoujo Shoujo is the best in terms of quantity. Can you imagine how much fun it must be to take regular baths with a dozen lolis and fuck them until they’re exhausted, oblivious to the fact that they’re your stepsisters?!
Ane wa Yanmama Junyuu-chuu
The majority of the hentai anime on this list are about teenagers, but Ane wa Yanmama Junyuu-chuu is not one of them. Maybe that’s why it’s so enjoyable to watch?
Aika, the female protagonist of this anime, is a married woman with two children who temporarily moved back into her parents’ house. Takuya, her stepbrother, is sick of Aika taunting him and walking around half-naked, despite the fact that her mature body turns him on. After a few beers, Aika laughs at the idea of treating Takuya like a man and jokes about breastfeeding him like she does her sons. Who would have guessed Takuya would take it literally and accept the challenge of sucking those delectable tits?!
Despite the fact that her husband and sons are in another room, Aika has no qualms about cheating on the man by sucking Takuya’s dick, and this isn’t even their first encounter! Yanmama, Ane wa Junyuu-chuu is a fantastic hentai anime about stepsiblings, as well as one of the best netorare starring a true MILF. In Episode 1, Takuya and Aika are fucking in the bathroom, and Aika’s eldest son knocks on the door to inquire what’s going on. Is that too much to ask?
I understand why NTR might turn some people off, but if you’re okay with it, please go watch Ane wa Yanmama Junyuu-chuu right now. You’ll be able to thank me later!
Conclusion
We’re all fans of the “help me, stepbro.” The “I’m stuck” meme is popular, but hentai anime are more inventive in depicting how a sexual relationship between stepsiblings can flourish. These recommendations demonstrate it!
Remember that there are no taboos in hentai anime, and there is no incest if people are not blood relatives. It all comes down to morality and how you perceive family.
