'''''My Balls''''' (''Oretama'' in Japanese) by Shigemitsu Harada: The fate of the world rests on one man's shoulders. Or, to put it more precisely, it rests in his right testicle.

Emmaniel, the Queen of Terror, is a demon on her way to destroy the world. Then, in an accident involving an angel, a SoulJar and a stream of urine, she is [[SealedEvilInACan sealed away]] inside the right testicle of perennial loser (and virgin) Satou Kouta. The angel informs him that if she remains sealed for the entire month, the world will avoid destruction. The only way for Kouta to keep her sealed is to not ejaculate for one month, or she'll escape. Thus Kouta must resist temptation for a full month, lest the world be destroyed.

He spends the remainder of the series fighting off dozens of HornyDevils on a mission to free the Queen of Terror, as well as the nigh-unstoppable advances from the hot co-worker he's had a huge crush on. HilarityEnsues.

Although this manga is not technically classified as {{hentai}} (''technically'' in the sense that FAR less explicit content ''has'' been treated as hentai), it deliberately skirts as closely as possible while still being publishable in a mainstream magazine. Be prepared for some ''extremely'' raunchy, explicit and hilarious content if you read it.

* Elyse: A lesser devil who initially tries to free Emmaniel. [[spoiler:[[HeelFaceTurn She eventually gives up that goal after developing feelings for Kouta and betraying the Queen.]] After successfully helping keep the Queen sealed, she goes on the run from the Queen's wrath and soon after, her feelings for Kouta.]]
* Emmaniel: The Queen of Terror. All-powerful (and sexy) demon queen trapped -- sigh -- in Kouta's balls.
* Irene: A succubus who also attempted to free Emmaniel. [[spoiler:She later decided to keep her sealed, as she wants to continue screwing all the hot guys on Earth before it gets destroyed.]]
* Michael: As in "[[ArchangelMichael The Archangel]]." Accidentally sealed Emmaniel into Kouta's junk.
* Minayo Aizawa: Kohta's hot coworker. Returns Kohta's feelings. HardDrinkingPartyGirl [[MyGirlIsASlut Nymphomaniac]]. [[spoiler:Succeeds, then fails.]]
* Satan: [[SheIsTheKing Herself.]]
* Satou Kouta: LoserProtagonist turned KavorkaMan.

%% This wiki has a guideline called NoLewdnessNoProfanity, make sure that you have checked it out before editing this particular series. If you did, have fun.
!!''My Balls'' provides examples of:

* ACupAngst: Elyse. It's actually something of a plot point.
* ADateWithRosiePalms: Kohta cannot even do that as it might release Emmaniel.
* AnatomicallyImpossibleSex: Despite the lurid amount of detail on the various workings and characteristics of the sexual reproduction organs, the series seems rather insistent on presenting the testicles full of ready-made semen. Emmaniel in particular complains that it's been backing up the longer she's trapped there.
* ArtShift: Frequently shifts to {{Chibi}} / KewpieDollSurprise (complete with [[HumanHummingbird flailing arms]]) when Elyse gets flustered.
* AttackItsWeakPoint: The pentagram marking on a demon.
* BabiesEverAfter: The last page of the series (besides the humorous 4 page epilogue) shows [[spoiler: Kouta and Elyse's children talking about how their mother was a demon, and their father saved the world.]] [[CassandraTruth No one believes them.]]
* BandageBabe: Isabella the Dead.
* BattleInTheCenterOfTheMind: What happens between [[spoiler: Kouta, Elyse, Emmanuel and Satan]] is pretty much like that.
* BenevolentBoss: Kohta's boss not only takes him out for a drink multiple times, but he also pays for a prostitute and for some time in a strip club. In ANY other situation Kohta would be in heaven.
* BlandNameProduct: The beer that Minayo likes to drink is "Badweiser". Kouta and Elyse visit "Mousey Land." Not to mention "Hage Dazee"
* BlessedWithSuck: Kouta's condition means females are throwing themselves at him now, but he can't actually make it with any of them. (He's a masochist so that's a semi-bonus to him.)
* BreakHisHeartToSaveHim: Elyse tries this, and instead of the desired effect HumanityEnsues.
* CannotSpitItOut: [[spoiler:Elyse]] can't admit her true feelings towards Kouta. [[spoiler:Eventually, she does, of course.]]
* CantGetAwayWithNuthin: Elyse is always interrupted while busy with Kouta.
* CantHaveSexEver: Arguably the premise of the manga. "Arguably" because Kouta somehow ends up having sex quite a few times without invoking the "escape clause."
%% * CaughtWithYourPantsDown: Obviously.
* ColdTurkeysAreEverywhere: Everything in the universe has aimed itself at Kouta to make him do the one thing he must not do.
* [[DealWithTheDevil Contract with a Demon]]: Kouta gets [[spoiler:Elyse]] to help him via one; the latter gains control over his soul as a result, which basically amounts to controlling his body while he's unconscious.
* CreepyCoolCrosses: Elyse wears one.
* CuteMonsterGirl: Tons of them.
* DeclarationOfProtection: When Kouta says this to Elyse, it makes her even more crazy because she already won't admit to herself that she has fallen in love with him, a mere mortal human.
* DidYouJustPunchOutCthulhu: Kouta essentially [[MindRape sexually dominates]] '''The Queen of Terror''' while she is trapped inside his testicle so he can relieve the sperm buildup.
* DoctorJekyllAndMisterJackDaniels: Minayo turns into a raging nymphomaniac when drunk.
* DoesThisRemindYouOfAnything: Inverted. Kouta's junk is made to look like the shark from ''Film/{{Jaws}}'' anytime Elyse pulls it out of his pants because it scares her.
* DoubleStandardRapeFemaleOnMale: Somewhat mitigated by the fact that Kohta would happily accept.
* DropDeadGorgeous: Isabella the Dead, [[BodyHorror or maybe]] [[FanDisservice not]].
* DudeShesLikeInAComa: Kouta does this twice, [[spoiler:first to Minayo in a drunken stupor, then to an unconscious Elyse during the full moon.]] With plenty lame rationalizations about it. Elyse can be said to do it pretty much every time Kohta is sleeping.
* DullEyesOfUnhappiness: Satan, most of the time.
* {{Ecchi}}: Consistently skirts the line between this and straight-up hentai.
* ElegantGothicLolita: Ares the Reaper.
* EroticDream: Emmaniel tries raping Kouta in his dream in order to escape; it doesn't work since [[CatapultNightmare he wakes up too fast]].
* ExactlyWhatItSaysOnTheTin: Titles don't get less subtle than this.
* {{Expy}}: Shunsuke's boss from ''Manga/Yuria100Shiki'' has almost the exact same character design and personality of Kohta's Boss from this series.
* {{Fanservice}}: Just about any female.
* FirstGirlWins: [[spoiler:Subverted. At first Kouta is only interested in chasing Minayo, but eventually realizes and admits his feelings for Elyse.]]
* {{Foreshadowing}}: Near the end of Chapter 2, [[spoiler:Kouta starts seeing Elyse naked because he is starting to have feelings for her even though they are enemies at that time. Guess what is the {{OTP}} by the end of the manga.]]
* GenderFlip: Satan.
* GenerationXerox: Kohta's mother apparently once had a demon sealed inside her uterus.
* GodIsGood: Though shackled by the letter of His own laws, He generally ensures that [[OmniscientMoralityLicense things work out for the best]].
* GoodAngelBadAngel: To be more precise, [[LoveFreak Dere-dere Angel]] and [[JerkAss Tsun-tsun Angel]].
* GoodWithNumbers: Subverted. [[CrowningMomentOfFunny He's not very good at the 7 row.]]
* HardDrinkingPartyGirl: Minayo goes from [[DoctorJekyllAndMisterJackDaniels demure coworker and would-be girlfriend into unstoppable nymphomaniac after only a drink or two]]. Of course she usually has a drink or two before meeting Kohta.
* HeelFaceTurn; [[spoiler:Elyse and Irene.]] In the final issue, [[spoiler: Satan decides to shack up with Michael. Yep.]]
* HornyDevils: All of them so far.
* HotAsHell: Satan is a woman. What's more, Satan is very sexy.
* HumanityIsAdvanced: In a non-alien twist. [[spoiler:Upon Hell deciding to just ignore Kouta and attack Earth instead of trying to release Emmaniel, The Archangel declares that war between the humans and devils would destroy humanity... But because of science and reproduction, humanity would take down the magical Devils with them in mutually assured destruction.]]
* TheImmodestOrgasm: [[spoiler:Near the end, young!Michael and Satan have sex with the purpose of purifying her; this trope happens, including a PillarOfLight.]]
* ImprovisedWeapon: Condensed milk and lotion. Breast milk.
* InconsistentDub: In the final chapter Irene appears in, she's referred to as Alice.
* {{Invisibility}}: Ash the Invisible.
* IWantMyBelovedToBeHappy: Subverted; because Elyse won't admit her feelings for Kouta, she tries to make him miserable. Of course he ''likes'' the abuse...
* IWasQuiteALooker: [[spoiler:Michael]].
* KavorkaMan: Kohta, whether by magical influence or not.
* LargeHam: Emmaniel, during the pregnancy chapter.
* LawyerFriendlyCameo: Angel*** Jolie in Chapter 28.
* LevelUpAtIntimacy5 would explain the "process" better.
* MagicalGirlfriend - Once Kohta stops pining after Minayo and goes for Elyse.
* MistakenForPregnant: Emmaniel claims that she is in an attempt to get out. After some... up-close inspection on Kouta's part and confession by the Queen, her ruse is found out.
* OhCrap: Kouta escapes a pair of rather smitten women while being chased by a devil with arrows much like Cupid's. He manages to flee and make his way on to a train. Right in the car for use by women only.
* OjouRinglets: What Elyse's horns become when she is in a human form.
* OneGenderRace: All the devils shown are female, even {{Satan}}! Averted in the case of the angels, as of the two angels we've seen, there was one of each gender.
* PaintingTheMedium: In chapter 26 Elyse speaks in random icons that Kouta calls demonese, it's "[[TakeOurWordForIt so scary]]".
* PillarOfLight: A few times, most notably when Emmaniel manifests or when [[spoiler: Michael sexes up Satan in the penultimate chapter.]]
* {{Pixellation}}: To prevent the target demographic from being exposed to Kouta's... thing.
* PowerPerversionPotential: Most of the devil's powers are actually based on this.
* ReallySevenHundredYearsOld: Elyse and a few other demons.
* {{Satan}}
* SealedEvilInACan: More accurately, sealed evil in a ball.
* SexFaceTurn: [[spoiler: Satan becomes an angel again after being "purified" by Michael]], complete with ImmodestOrgasm and a PillarOfLight.
* ShareTheMalePain: When Emmaniel's arm comes out of Kohta's penis.
* ShownTheirWork: Sometimes, it can seem as if this manga is a shameless plug for a health textbook.
* {{Squee}}: Irene's reaction to Kohta confessing to Elyse.
* {{Stripperific}}: Elyse.
* TemptingFate: Kouta wandered on to holy ground to find a place to take a leak. He may as well have been holding up a metal rod and begging for lightning to come down while he was doing it.
* TimedMission: Kouta has to make it without ejaculating until August 1st.
* TookALevelInBadass: [[spoiler:Kouta]] in the hours leading up to the deadline.
* TooKinkyToTorture: In this case however, it plays into the hands of the baddies.
* TooManyBelts: Lady Emmaniels costume is made of this... and some strategically placed shadows.
* {{Tsundere}}: Few protagonists can push the "tsun" as hard as Elyse does. Parodied in chapter 38, where [[spoiler:the tsun- and -dere sides of her personalities start arguing and Elyse shoos them away. She then remarks that "it's not like she enjoys being tsundere".]]
* WeaksauceWeakness: Touching a demon's pentagram.
* WhatMeasureIsANonHuman: The epilogue.
* WidgetSeries
* YourPrincessIsInAnotherCastle: Humanity is finally safe... except that Elyse is a demon and Kouta has realized he loves her. Now he only has a week to make her admit she loves him too (and thus cause her to become human to invoke the "safety clause" that keeps humanity safe for the week).
* ZettaiRyouiki: Baphomet; Elyse during her "date".
