Domina Liza's femsub 'brat' is in trouble - she is meant to lose weight and has gained instead! So Liza decides the single tail whip is the only way to deal with this. First she lightly flicks the whip against brat's back, lulling her into a false sense of security...but then the whip cracks and brat cries out realising that this is no longer a game. The whip cracks against her skin over and over again whilst Liza relishes the pain she is inflicting on her disobedient female slave...
