The story takes place in Seiran Island, where an unique law not only allows free perverted sex, but makes it compulsory. Junnosuke Tachibana and his sister Asane return to the island as transfer students. However, he is a proud virgin that believes there shouldn't be sex without love. Together with his newfound friends Nanase Katagiri, Hinami Watarai and Misaki Hotori, he forms the anti-copulation front, also known as No Love No Sex (NLNS), with the mission of destroying the perverted laws, all while escaping the SHO and keeping their virginities intact.
A sequel titled NUKITASHI 2 was released in July 2019. A manga adaptation illustrated by Mameojitan began serialization in the Ultra Jump magazine in November 2021. It only covers Misaki's route. An anime adaptation
was announced on 28th January 2024.
NUKITASHI contains examples of the following tropes:
- Absurdly Powerful Student Council: The SS (SHO students) commitee is a group of students that receive special grants from Seiran Health Organization in exchange for protecting and enforcing the pervert laws at Minotsuki Academy. It includes the school council and the disciplinary comittee and they organize large-scale promiscuous events and competitons, often with the intention of catching the anti-copulation front. Some SS members lead military battalions to supress rebels or rioters.
- And Now for Someone Completely Different: Just after the opening movie plays, Hinami is introduced in a few scenes from her point of view. They show her daily life and insecurities about her appearance. The POV switches back to Junnosuke by the time of her Attempted Rape.
- Alternate Character Reading: The word watashi (I) in the long Japanese title is written like 貧乳. This is normally read as hin'nyuu and means "small-breasted", making a reference to Hinami.
- Arc Words: "Experience repeated hardships, overcome numerous difficulties and finally attain the fulfillment of your goals through your trials and tribulations." This is the life philosophy shared by Fumino and all of her family.
- Ass Shove:
- In Nanase's Route, Junnosuke infiltrates the SHO headquarters to retrieve personal data of island residents from the servers. He brings a buttplug-shaped USB drive hidden in his rectum. Later on, he does the same with his solid anal vibrator in order to bypass the limit of only one adult toy at school.
- Misaki had an accident when she got a magical girl figure stuck up her ass. In her route she likes to penetrate her enemies with an anal vibe at max power.
- Attempted Rape: Suffered by Nanase, Hinami and Misaki in the common route. Nanase gets pressured by an impatient classmate who's tired of getting his encounter delayed, Hinami is assaulted in the middle of the forest and Misaki is forced in an illegal porn shooting. In all of these incidents, Junnosuke and his growing group of friends arrive just in time to fight off the aggressors.
- Auto Erotica: One of Junnosuke and Misaki's H-scenes takes place in the mirror van. It's a warmup to the strategy consisting of picking up girls around the island and having him cure their brainwashing.
- Big Damn Heroes: In the true route, the NLNS travel all the way from Seiran Island to Sakimori's state in order to rescue Fumino, who had been brutally tortured in the basement.
- Bigger Is Better in Bed:
- Junnosuke is the most well-endowed man on the island and he shocks Kouki Senba, Ikuko and other SS girls, who all had their fair share of sexual experience. But still, he can't get over his trauma and still feels miserable about his member, something which the SHO can't understand.
- Touka, Hitoura and Teshima suggest an exaggeration of this, that Jun could use his hidden power to make any female submit to him through sex and thus conquer the island or even the entirery of Japan.
- In Misaki's route, the reason Jun can bang the islanders and cure their sex-induced brainwashing is that his equipment is bigger than Teshima's artificially enlarged one.
- Bland-Name Product: Some real-life adult goods appear this way: Papaa (Pepee) lube fountains and TENMA (TENGA) Eggs.
- Chekhov's Gunman: In Nanase's route, Touka tells about her apprenticeship at Sakimori's house. Sakimori is the name of the elder man that sponsors the NLNS and he is the Big Bad of the True Route.
- Deus Sex Machina:
- Junnosuke, Nanase, Hinami and Misaki find a gel wall for ass wall play in the forest. They activate it and it solidifies, trapping the girls. The only way to turn it off is to bring the participants to orgasm. At this point, the player can decide which heroine will Junnosuke help out first, and it sets the story towards her respective route.
- In Misaki's route Teshima brainwashes almost the entire population of the island into accepting a new perverted law where all sex will be paid. The catch is that he achieved this with his dick, and brainwashed people can get back to normal if they get even more satisfying sex.
- Double Standard Rape: Female on Male: The rape attempts on the heroines are portrayed dramatically while Junnosuke getting violated by SS girls is shown to only hurt his pride at most. It doesn't help that in these scenes he manages to overpower his aggressors and knock them out.
- Elaborate Underground Base: When Junnosuke and Nanase escape from the SS, they find an underground base inside a cave. It connects to the school and it's equipped with computers, 3D-printers, and the necessary facilities to stay the night. When Junnosuke founds the anti-copulation front, he establishes the hidden base as the headquarters.
- Everybody Has Lots of Sex: The main selling point of Seiran Island, owing to the perverted laws. Residents and tourists alike are expected to do it in public regardless of the place or time. They are also forbidden to stick to a single partner. Infractors who don't indulge in promiscuity get punished with even more sex. Moreover, all tourist attractions and businesses are sex-themed.
- False Utopia: Seiran Island is advertized as a paradise where you can get it on any way you want and Ran Hanamaru claims that the crime rate is near zero-percent. However, the SHO and SS heavily regulate sexual behavior, not recognizing homosexual acts and punishing those who prefer to stay with only one partner. The perverted law can also be used as an excuse to force one's fetish into others. There are serious security threats such as sexual violence in the unattended mountains and the Yakuza who are taking revenge on the island for the decline of the underground sex trade.
- Forgotten First Meeting: Junnosuke recalls having a childhood friend who didn't bully him like the rest of the school but that he had to part ways with after hurting her in a certain incident. He doesn't remember that she was Nanase, but she remembers him.
- Goroawase Number: Misaki tries inputting the following combinations in a locked door: 1919 (iku iku, meaning "cum, cum"), 4545 (shiko shiko, "fap, fap"), and 8585 (paco paco, "plap, plap").
- Hot Springs Episode: In Misaki's route, after a long day of training for the Nut Games, the NLNS members go to relax in an outdoor hot spring near the base. At first, they bathe together but then Junnosuke and Misaki get left in the pool due to Asane's Nosebleed. He fails to hide his Raging Stiffie and in the end he tells Misaki about his past and body complex.
- Improbable Weapon User: NLNS members specialize in combat using adult toys so they don't raise suspicions in the personal belogings check at school. Junnosuke wields a solidified anal vibrator and Nanase throws egg masturbators acting as flashbangs or smokebombs. Apart from toys, Hinami hits with a folding chair and Touka flings coins at opponents.
- Itasha:
- In Misaki's route, the NLNS have her trusty mirror van "Aikaze" remodelled to "Aikaze Mk. II". It comes equipped with armoring, dildo cannons and a Misaki-themed paintjob.

- New Game Plus: After clearing the routes of Nanase, Hinami and Misaki, the title screen changes and when starting a new game a short prologue from the point of view of Fumino is shown. Reading it is required to unlock the true route.

- The pervert law is an inversion of this. So-called procreative activities are mandatory for everyone in the island, and those who don't participate get arrested and punished with even more sex.
- Played straight in the true route when Sakimori takes over the island. He turns the perverted law in its head, banning any and all sexual activity, even at home.
- Omega Ending: Completing the routes of Nanase, Hinami and Misaki unlocks the true route, which has Fumino as the heroine.
- Out with a Bang: Downplayed. SS and SHO girls sometimes pass out from having sex with Junnosuke and later don't remember well what happened.

- Running Gag:
- Background mob characters are frequently heard getting it on in the streets, at the beach or at school. They moan corny lines and the males always scream "Get pregnant, bitch!".
- Asane worrying about not taking enough "nanasenium", a molecule allegedly present in food or sweat produced by Nanase.
- Misaki arriving at the base and failing to get noticed for a while. She tries flashy methods like announcing her presence with a flashbang.
- Self-Censored Release: The Steam version takes this to a extreme. It only contains the first scenes of the common route with all sexual references censored and it ends abruptly. Downloading the +18 patch from Johren is mandatory to experience the full story.
- Sex Tourism: The main source of income for the island are visitors who come to get laid. The pervert law, the nudist beach, the Lewd Land amusement park and other facilities are designed to attract them.
- Sleazy Photoshoot: Played for laughs in Nanase's route. When Junnosuke and Nanase go to a photo booth, it was programmed to ask for nipple and crotch pics in order to retouch them. She reluctantly flashes her privates for the camera.
- Snowball Lie: In Misaki's route, the NLNS carry out a plan in which they calmly exit the school while pretending to have had a fivesome. They have just managed to convince Rei when Misaki blurts out that Junnosuke penetrated the four girls at the same time with both hands and feet. It goes downhill from there , with miscalculations on the number of appendages and genitals, and the next morning Junnosuke turns into the subject of outright fantastical sex gossip and earns the nickname "Six Million Glory Hole Man".

- STD Immunity: Justified. The SHO regularly carry out medical checkups on everyone in the island and punish those who skip them. No one has to worry about diseases no matter how much sex they have.
- Stripperiffic: Female SS uniforms consist of a miniskirt, thigh-high stockings and an open vest that exposes the underwear and the midriff. They dress like that even when training or fighting.
- Super-Toughness: In the final fight, Junnosuke uses the "Homo Erectus" technique so that his whole body gets as hard as an erect penis. In this state he walks in front of the rest of the team blocking all bullets and RPG warheads without flinching.
- Suppository Gag: As Junnosuke finds out when taking care of Ikuko, common medicine sold in the island is actually in suppository form.
- Ventriloquism: In Misaki's route, Junnosuke is violently humping a sex doll trying to decieve Ikuko, when suddenly the doll appears to moan by itself. Ikuko is convinced that it was asphyxia play and leaves, and then Misaki reveals to have acted out the voice of the toy.
- Vitriolic Best Buds: Junnosuke frecuently slut-shames Nanase despite being his first comrade of the NLNS. She fights back mocking his erectile dysfunction.
- You Need to Get Laid: Junnosuke's antagonists strongly recommend him to solve his frustrations by boning all the women in the island into submission.
