Lily

Lily (portrayed by Mila Kunis) is the deuteragonist of the film, and Nina's rival and lover. She is a new dancer in the ballet company, and represents the opposite of Nina's personality. She also competes with Nina for the role of the Swan Queen. However, it's very clear that she and Nina share romantic and sexual attraction between each other.

Nina and Lily's relationship
After dancing together in the club under the effects of ecstacy and alcohol, Nina and Lily take a taxi together to Nina's place. In the back of the cab, Lily pokes Nina's leg to call for her attention and their eyes meet, with obvious sexual tension between them. Lily then proceeds to move her hand under Nina's pants and gently rubs her crotch. Nina becomes aroused and enjoys, as Lily continues to caress her crotch. However, before climaxing, she stops Lily and just holds her hand likely not wanting to climax in the car. The two of them stay that way, with Lily giggling over it and Nina calmly looks over the window.

After they arrive to Nina's home, Nina and her mother have a frigid discussion. Nina drags Lily to her bedroom, where she barricades the door to prevent her mom from entering. Lily hugs Nina before Nina completely closes the door. Nina then turns around and looks at Lily, locking their eyes with even more sexual hunger than before. Nina then rushes to Lily and starts passionately french kissing with her. Lily kisses and nibbles on Nina's neck and caresses her curves.

Lily takes off Nina's shirt while they continue to passionately kiss. Nina removes Lily’s pants shoves her on the bed and then removes Lily’s shirt as Lily giggles. Lily pulls of Nina’s pants, throws her prey onto the bed, pulls off Nina’s panties and throws them into the corner of the room. Lily lays on top of Nina and passionately kisses her and slowly moves down Nina’s body while massaging Nina’s tiny breasts. Lily licks Nina’s thigh and forcefully spreads her legs. She extends her long tongue into Nina’s vagina.

Lily raises her head, Nina briefly sees herself and sits up panicking. Lily gently shushes Nina and kisses her on the mouth before licking her stomach on her way back down. Lily’s tongue enters her prey’s vagina again and she places her mouth on it. Nina moans loudly as Lily begins to eat her vagina. Then she starts to scream as Lily devours her. As Nina breaths heavily Lily gets off her prey, stands up, wipes her mouth and calls her a sweet girl. Then Nina sees herself in Lily’s place. The doppelgänger throws a pillow over Nina’s face and she passes out.
