A Spanish sister's naughty habits have finally pushed her brother over the edge. He's decided she needs a firm hand, and he's not afraid to give it to her. Her culottes, a thin barrier between his hand and her flesh, do little to protect her as he begins to spank her. She squirms, trying to escape the stinging blows, but he holds her firm. Her moans fill the room, a mix of pain and pleasure, as he continues to redden her ass. Each smack sends a jolt of electricity through her, awakening desires she's long tried to suppress.
