When their strict mother, Lily, is out shopping, her daughter Nicolette misbehaves. She tries to persuade good-two-shoes sister Ana to join her, but Ana is a good girl and refuses. Lily returns unexpectedly and catches Nicolette, and there is only one possible punishment for such bad behaviour, a good over the knee (otk) spanking. Lily severely scolds Nicolette and pulls up a chair before sitting down, and pulling Nicolette over her knee. She starts the spanking using a slipper and uses that and her hand to give Nicolette a good hard punishment she won't forget. Nicolette thinks her punishment will end soon but Lily has other ideas and after a while she raises Nicolette's skirt to spank her over her white knickers. Ana watches from a secret spot and takes great delight in viewing her sister's punishment Nicolette is shocked when Lily decides to pull her knickers down and spank her on the bare. When the knickers come down we see Nicolette has a beautiful bubble butt that is perfect for spanking. "If you're going to act like a naughty girl, I will treat you like one" Lily asserts and the painful spanking continues until Nicolette's bottom is bright red..a very well smacked bottom. Includes pre and post shoot interviews with Lily and Nicolette..discussing their expectations of the shoot, and how they found it etc. Please note that the dialogue is in Spanish..but the language of spanking is universal
