Iris Wildthyme in the Doctor Who Expanded Universe, although whether she physically matches the description depends on the incarnation. The Beryl Reid incarnation certainly fits the bill, the Barbarella and Shirley Bassey ones not so much, and the Katy Manning Iris is more of a Mrs. Robinson. In JoJo's Bizarre Adventure: Stardust Crusaders, Joseph accidentally peeps into a bathroom stall on a woman like this, who instantly becomes obsessed with him and tries to seduce him. Hilarity Ensues.

We (still) like to keep our understanding of masculinity connected to our understanding of maturity. We’d never had a female anchorwoman deliver our news until recently, we don’t often let female columnists explain the news, and we’ve never had a female president to make the news. For many Americans, being a real grown-up requires a penis. And if you’ve got that, even if you’re only 15, you must have the maturity and the manliness to know what you want to do with it—even if that involves intercourse with a 42-year-old. Who among us would say the same thing about a 15-year-old girl? In the Delta episode of Pokémon Omega Ruby and Alpha Sapphire, Zinnia's grandmother tells the player that she sees Steven as a "silver haired dreamboat" despite Steven being in his mid 20s. This was not an isolated incident. For the next three and a half months, Jason estimates, the two continued having sex at the house and in her car. “Nobody suspected anything,” he says. “And I didn’t want nobody to know because I was messing around with her daughter. I found it funny that Diane was letting me stay at her house when she knew about that, but I never asked her why: I figured she was doing it because she wanted something.” “Sometimes, the woman is not much older psychologically than the boy is in her developmental stage,” says one psychologist. “So she’s having sex with a 14-year-old, and in her head, she’s 14, too. She’s getting the attention she never got.” From left: Diane Demartini-Scully, Age: 34, Age of Boy: 16; Debra LaFave, Age: 24, Age of Boy: 14.

When they show up in a Darker and Edgier show, which is rare, they're often used to show the unfortunate fate of women who let their sex drives lead their lives or, inversely, the result of too much prudishness. Doctor Who: The bus full of old people in "The End of Time". Minnie "The Menace" Hooper in particular; she even gropes the Doctor. Granny from Squidbillies. She built a monster out of human corpses to keep as a friend with benefits, and forged an ancient love letter and faked a coma to try and sleep with the ghost of Robert E. Lee.

At the end of the episode "Bravo Dooby Doo", a crossover with Scooby-Doo, Johnny's elderly Aunt Jebidisa hits on Shaggy. You could clearly hear Letourneau imbuing her student with power; trying to convince the public as she’d convinced herself that Fualaau—her lover, her hero—was on more than equal footing with her: “He dominated me in the most masculine way that any man, any leader, could do.” If you conceive of teenage boys as walking heaps of lust, you probably conceive of attractive adult teachers who hit on them as public servants in more ways than one.

Examples:

It seems that three old ladies were standing at a bus stop when along came a flasher and opened his raincoat. Well, the first old lady had a stroke. The second old lady had a stroke. The third old lady tried to have a stroke but her arms were too short. Dirty old(er) women do not reside exclusively in states with alligator problems; we have our fair share in the New York area. In August, Sandra Beth Geisel, a former Catholic-school teacher and the wife of a prominent banker in Albany, was sentenced to six months in jail for having sex with a 16-year-old, and she has admitted to sleeping with two of her 17-year-old pupils. (The presiding judge in the case infuriated the youngest boy’s parents when he told Geisel her actions were illegal but that her youngest sexual partner “was certainly not victimized by you in any other sense of the word.”) In October, Lina Sinha, an administrator and a former teacher at Manhattan Montessori on East 55th Street, was charged with second- and third-degree sodomy and third-degree rape for allegedly having sex with a former student—who is now a cop—for four years starting when he was 13 and she was 29 (she denies the charges). And last May, Christina Gallagher, a 25-year-old Spanish teacher from Jersey City, pleaded guilty to second-degree sexual assault of a 17-year-old male student. Lady Cassandra counts, considering she enjoys feeling herself when she possesses The Doctor and Rose. In Love & Pies, Amelia's great-aunt Esme is too "interested" in her and Joe's first date and assumes that the birds and the bees happened between them. Amelia reprimands her for wanting the dirty details right in front of her kid daughter Kate, when the date itself was actually innocent. When Joe tells Esme that he wore nothing to the date, she immediately assumes that he and Amelia had "the birds and bees" going on when Joe meant that he wore "nothing important", meaning that he didn't dress fancy for the date.
