London River is a caring, medical professional with a penchant for helping teenage girls learn about sexual health. She gives Riley Star a check up and discovers that the young lady has been sexually active with boys, but that it did not feel good. London wants to show this impressionable girl that sexual contact should be pleasurable, so she takes matters into her own hands. She has Riley undress and then shows her how to properly fuck. She gets her nice and wet, showing her what a good cunt rubbing should feel like. Then she eats her twat, teaching her about the joys of the female orgasm. Looks like London really knows how to lend a helping hand!
