* In ThePenguinsOfMadagascar Hans the Puffin tries to do this to Skipper in "Huffin And Puffin". It kind of fails...

* Ryujin of MobTies informs Sidney Burns that if he marries Mika, Ryujin's sister, he will kill Sid, in the very first issue. This puts Sid in a bind, as Papa-san, Mika's father, will kill Sid if he doesn't marry Mika.

* Inverted in [[{{hayate the combat butler}} Hayate no Gotoku]]. Kaoru takes Yukiji on a vacation during Golden Week and attempts to confess his feelings for her. He doesn't have the courage, so instead he asks if Hinagiku has a boyfriend. Yukiji's eventual response is asking what he likes about Hina.

--->'''McKay''': She's my sister, and she's married.

--->'''McKay''': Sure you were. I've seen that look on your face before, [[BoldlyComing Kirk]].

* In most societies, [[YourMom insulting someone's mother]] is one of the nastiest insults around. In Kuwait, however, you can insult Mom all you like. Insult a Kuwaiti man's ''sister'', on the other hand, and you will find yourself on the receiving end of some ''very'' nasty fury.

* HarryPotter gives us an interesting inversion: Ron doesn't seem to want Ginny to date anyone ''but'' Harry. Harry is blind to this, however, and spends a lot of time worrying that he shouldn't act on his feelings for her.
** Ron's just plain uncomfortable with his sister dating ''anyone'', a bit hypocritical once he hooks up with "Lav-Lav". Apparently, he eventually decided that if she ''had'' to date someone, he would rather it be his friend instead of some stranger.
** The whole ordeal led to a {{Ho Yay}} laden part of the book: "The argument raged in Harry's head: Ginny or Ron?"
** Maybe you can see things in that order: Ron doesn't want anyone to date his sister. His best friend kisses her. Now it's up to him: tolerate it, or putting their friendship at risk? While weighting it, Ron suddenly realizes that he is the best guy in any way for Ginny.
* A lot of the WillTheyOrWontThey tension in the ''ThePrincessDiaries'' books has to do with the main character's crush being her best friend's brother. [[spoiler:When they get together, everything's fine. But when they break ''up''...]]
* In William Faulkner's ''The Sound and the Fury'', Quentin Compson massively fails to "protect" his sister from the many, many men she's having sex with, despite the fact that he is so desperate to keep her off limits. He loved [[GratuitousEnglish "some concept of Compson honor precariously and (he knew well) only temporarily supported by the minute fragile membrane of her maidenhead as a miniature replica of all the whole vast globy earth may be poised on the nose of a trained seal. Who loved not the idea of the incest which he would not commit, but some presbyterian concept of its eternal punishment: he, not God, could by that means cast himself and his sister both into hell, where he could guard her forever and keep her forevermore intact amid the eternal fires."]]

* In the second episode of ''KimagureOrangeRoad'', Kyosuke and his pals (ThoseTwoGuys) are ogling a leotard-clad aerobics class from a nearby restaurant. They soon see that Kyosuke's younger sisters are in the class, and sure enough, Kyosuke almost immediately covers the other boys' leering eyes.
* When [[DeathNote Touta Matsuda]] shows interest in Light's sister Sayu, who has grown into quite the cutie, no one is thrilled. [[PapaWolf Specially, Matsuda's boss Soichirou... her]] OverprotectiveDad.
** In the manga, L once wonders if Sayu could be Kira. Light ''screams'' at that.
*** But that's not the BigBrotherInstinct, that's good old-fashioned {{Pride}}. Light is outraged that L would overlook ''him'' as a suspect and give Sayu credit for his work instead. For his own part, L is provoking Light to test his response - Sayu is never seriously considered as a suspect.
**** YourMileageMayVary on this one since, [[AllThereInTheManual according to the the Guide Volume (The thirteenth volume)]], The person he cares about most [[AGodAmI besides himself]] is his sister Sayu.
* Frey in ''MythicalDetectiveLokiRagnarok'' is like this when Freya is around Loki. What he doesn't realize is Freya is doing all the flirting.
* Komui Lee in ''[=~D.Gray-Man~=]'' has this ''bad'' regarding his little sister, exorcist ActionGirl Lenalee Lee. At one point Inspector Link actually ''blackmails'' Allen by threatening to tell Komui that he is alone in a locked room with Lenalee. Allen immediately apologizes and opens the door. And when someone was ogling Lenalee, Komui's coworkers gave us this wonderful quote:
-->"Section Chief Beck, I would advise you [[MaleGaze not to look at Lenalee that way]]."\\
"Why? Does she have a lover?"\\
"She has a ''[[KnightTemplarBigBrother brother]]''."
* Inverted in [[{{hayate the combat butler}} Hayate no Gotoku]]. Kaoru takes Yukiji on a vacation during Golden Week and attempts to confess his feelings for her. He doesn't have the courage, so instead he asks if Hinagiku has a boyfriend. Yukiji's eventual response is asking what he likes about Hina.
** Yukiji is shown to be rather caring about Hina, so it's not quite clear how the rest of that conversation goes.
* [[CodeGeass Lelouch and Nunnally.]]
** Unless you're Suzaku, in which case Lelouch did at one point consider the idea rather valid, and [[spoiler: it still may be, despite Lelouch being dead]].
* In RaveMaster, Haru invokes this trope when he learns of the [[IfYouKnowWhatIMean relationship]] between his sister Cattleya and [[spoiler: Shuda]].
** He did this earlier when, another guy was dating Cattleya and broke up her heart. So naturally, when he saw said guy again, he made every effort to punch him out again. Not to mention [[spoiler: Shuda]] himself when finding out about that guy, he wanted to chop him up to pieces also.
* The ''{{Yu-Gi-Oh}}!'' anime has type four, or maybe type five with Joey and his sister, Serenity. This mostly affects Joey's best friend, Tristan, who is nuts about Serenity (while Serenity herself sees Tristan as a friend).

* As the third page quote indicates, Stephen Lynch's "Best Friend's Song" subverts this. Mark Teich is fine with Lynch sleeping with his sister... he just has to pay first.
** Note that [[spoiler: She's in junior high]] It's that kind of song...
* In the music video for the BlackEyedPeas song "Tagalog" Apl.de.Ap does this for his sister Jasmine.
* EltonJohn's "Your Sister Can't Twist (But She Can Rock 'n' Roll)," in which he brags about having had sex with a friend's sixteen-year-old sister.

* In Chaucer's ''Troilus and Cressida'', Pandarus, trying to find out who Troilus is in love with, promises to help him win her even if she were his sister.
* ''WestSideStory'', of course. "Get your hands OFF my sister, American scum!"
** Except that the above line is directed at an enemy, not a friend, and said sister is actually ''supposed'' to be with her brother's best friend, a coupling of which said brother implicitly approves.
* The song "Don't Tamper With My Sister" from ''On A Clear Day You Can See Forever'', though the complaint here is just that it's in public (and the character is only [[BoyfriendBluff pretending to be her brother]]).

* ''FreshPrinceofBelAir''. Carlton with Ashley. With Will its more of a case of 'My Cousin is Off Limits'. Strangely neither of them care about who their older sister/cousin Hilary dates or sleeps with. In fact Carlton tried to get into university by advising the university rep how to get Hilary into bed and advised her to get out of problems with the IRS by wearing sexually provacative clothing.

[[IThoughtItMeant Not to be confused]] with BrotherSisterIncest.

* Maxim Magazine codified the 24-hour rule as a "Man Law."
** What 24-hour rule? Do you have to wait a full day after someone stops seeing their own sister before you can?
*** It's up there, on the trope description.

**** [[YourMileageMayVary]] on this one since, [[AllThereInTheManual according to the the Guide Volume (The thirteenth volume)]], The person he cares about most [[AGodAmI besides himself]] is his sister Sayu.
