Mila Kunis (Lily) and Natalie Portman (Nina) in "Black Swan". Nina is a ballerina in a New York City ballet company whose life, like all those in her profession, is completely consumed with dance. She lives with her obsessive former ballerina mother Erica who exerts a suffocating control over her. When artistic director Thomas Leroy decides to replace prima ballerina Beth MacIntyre for the opening production of their new season, Swan Lake, Nina is his first choice. But Nina has competition: a new dancer, Lily, who impresses Leroy as well. Swan Lake requires a dancer who can play both the White Swan with innocence and grace, and the Black Swan, who represents guile and sensuality. Nina fits the White Swan role perfectly but Lily is the personification of the Black Swan. As the two young dancers expand their rivalry into a twisted friendship, Nina begins to get more in touch with her dark side - a recklessness that threatens to destroy her.
A really amazing movie worth watching, with Mila and Natalie lighting up the screen with their kissing. One of my top 5 movies.

If you haven't explored international/European movies, they are a source of many great movies and genres, often rivaling the best that Hollywood can offer, and certainly usually better than the dreck that comes out from the US. This isn't a blockbuster, but offers great fap... errrr, visual stimulation. 2010's "Room in Rome" stars Elena Anaya (Alba) and Natasha Yarovenko (Natasha). A young Russian woman named Natasha is soon to be married and is on holiday in Rome where she meets Alba. She accompanies Alba to her hotel room as a curious acquaintance and stays as a growing friend. In this room in Rome, the two women come to know one another intimately over the course of the night, and explore and discover themselves along the way. Only the break of day threatens to break their newly forged bond.

Denise Richards (Kelly Van Ryan) and Neve Campbell (Suzie Toller) in 1998's "Wild Things". In south Florida, a high school counselor is accused of rape by a manipulative rich girl and her trailer trash classmate. The cop on the case begins to suspect a conspiracy and dives into an elaborate and devious web of greed and betrayal to find the truth.
I can't say Denise is a great or even good, actress. IMHO, she can be rather wooden in some movies (e.g. as Christmas Jones in "The World Is Not Enough"), miscast in others (e.g. as Carmen Ibanez in "Starship Troopers") or she's just downright annoying in pretty much everything else she's done. But damn, she has a fine body, and she and Neve definitely make this movie light up. The pool kissing scene is classic!
The only downer with the scene is that Neve Campbell, unfortunately, exerted her no nudity clause. So, we were not able to get Denise/Neve booby mashing action. As you can see, only Denise is up to the task of showing us her assets.

Unfortunately, have not yet found a good video source of the clip yet (i.e. a source that doesn't overly spam you while you're watching). So, you get an GIF that I found.

Finally, we present Salma Hayek ("Frida Kahlo") and Ashley Judd ("Tina Modotti") in "Frida" (2002)
"Frida" chronicles the life Frida Kahlo shared unflinchingly and openly with Diego Rivera, as the young couple took the art world by storm. From her complex and enduring relationship with her mentor and husband to her illicit and controversial affair with Leon Trotsky, to her provocative and romantic entanglements with women, Frida Kahlo lived a bold and uncompromising life as a political, artistic, and sexual revolutionary.
Aside from the great kiss, you also get to enjoy a lovely tango scene.
