In the final segment of "Advanced Anatomy", Sophie returns Katrina's favor for an orgasm by munching on her womanhood before bringing her to an intense orgasm. She licks, sucks, fingers, and spits on her clit while she lays on her back, spread-eagle on the bed, with her feet up in the air. Her cute nubile body shakes and shutters as Sophie rubs her swollen vagina to a climax. Now that she's been completely corrupted by her stripper roommate, Katrina has enjoyed having sex with another girl so much that she feels like she's been turned into a lesbian.
