In The Vision of Escaflowne, when Allen Schezar is locked up by his king, Princess Millerna comes down to the dungeons, seemingly trips and Shows Some Leg to the guard, asking him to check her foot. The blushing guard bends down to investigate and gets a Tap on the Head from Allen's lieutenant Gaddess.
Black Widow started off as a villain but did a Face-Heel Turn and started working for SHIELD. She still uses sex to get information out of SHIELD's enemies. It is part of her "specific skillset" after all.

A lot of problems in the first trilogy of the Kushiels Legacy series are solved by having the High-Class Call Girl protagonist, Phedre no Delunay, find the right person to sleep with. This ranges from seducing an on-the-fence admiral to infiltrating the harem of a horrific dictator.
The episode "Mirror, Mirror" from Star Trek: The Original Series shows Lieutenant Uhura get minxy with Mirror-Sulu, so that he doesn't notice a warning light that signals transporter tampering by Chief Engineer Scott. Once the danger is past, Uhura switches off the sexy.
In the series as a whole she is a minor example. Her status as a Companion granted the Serenity crew a level of respectability, allowing them to get around more easily.
In a full-blown moment of the trope, her involvement with the son of the guy who runs Canton gave him the confidence he needed to stick up to his dad, and sooner or later when the responsibility passes to him, he'll rule with a gentler hand.
Lexx. Xev was not above using her libido to get what the crew needed. That she finally got the chance to satisfy said libido was of course an added bonus.
Margery Tyrell. She's sexy and she knows it. And what does she do with her sexiness? Keeps Joffrey from being too cruel.
Shae counts to some extent, being Tyrion's main emotional support.
Ros is likewise skilled at using sex to get information. She feeds said information to Varys, who uses it to keep Sansa away from Littlefinger. This gets her killed.
Of Dany's many achievements, convincing an enemy general to assassinate his two co-generals and grant her control of his army, simply by being the sexiest woman he's ever met, is pretty close to this.
The Walking Dead. A minor example, and possibly a subversion. During the third season, the survivors are being terrorized by a man known as The Governor, whom Andrea just happens to be involved with. Knowing this, Carol suggests she take a page out of Jael's book; sex him to exhaustion, then impale his skull in his sleep. But after he's finally out, she can't bring herself to do it.
The heroine of the TV show Lost Girl is a succubus who uses her magical seduction powers to flirt information out of bad guys regularly, and occasionally knocks them unconscious with a kiss.
Mrs. Tigh may be a woman of questionable morality, but her liaisons with the Cylon Cavil were ostensibly to secure her husband's release from the detention center, where he was likely being tortured, and hadlost an eye.
Baltar's Head-Six bounces like a pendulum between this and The Vamp every few episodes or so.
Jael: Invited a fleeing enemy general of an army who had oppressed her people for decades into her tent, shagged him into submission, then drove a tent peg through his skull while he slept.
For that matter, to a slightly less fatal degree, Esther: Used her charm, wit, beauty and sex appeal to get a king to marry her, so she could get him to countermand an order to kill a bunch of her people.
And to an even more fatal degree, Judith. Similar to Jael, oppressive enemy, uses her sexuality to get close to the guy, then kills him while he's vulnerable. She takes it a step further though... (See: Holofernes).
The Simpsons: Played for Laughs. The episode "Large Marge" has Homer Simpson get masticated by an angry elephant. The Springfield Police are ready to shoot the beast, but Marge realizes that the police are very likely to shoot Homer as well. To allay this, Marge flashes her enhanced breasts to the crowd, and the police stop to ogle and drool. This gives Krusty the chance to comment, "Check out those mogumbos." This key word stops the elephant's rage, and it spits out Homer intact.
Aladdin: Jasmine had her moment, keeping Jafar distracted long enough for Al to get the lamp back. Backfired, since Al was (rightly) too squicked out upon seeing her kiss Jafar to keep moving toward the lamp, losing a few crucial seconds.
Songstress Angel attempts to seduce Mok in Rock and Rule so that Mok will abandon his Evil Plan to summon a demon during a rock concert. Unfortunately, Mok is Ax-Crazy, and laughs off the attempt, ordering his minions to "take her away."

Five hats means that five tropers think it is ready to publish.
You are saying that you think this draft is ready to be published. That means the description is not ambiguous,
it doesn't duplicate an existing trope, there are at least three examples, and the title makes sense.
Is that what you meant to do?
You are saying this draft has a ready-to-publish hat it does not deserve and you are taking it back.
