Katie and her step-mom and her step-brother sometimes engage in behavior that is... shall we say, 'unusual' for family members to engage in sex. Katie actually takes her own step-brother's virginity in 'Deflowered By My Step-Sister'. She cock-teased her step-brother mercilessly when her step-mom put her step-brother's cock in a chastity devise, ultimately leading to her being fucked by her step-brother when he got out of it, in 'Cock-Teased In Chastity'. And when her step-brother used foul language in front of step-mom...instead of rinsing his mouth out with soap, step-mom made him lick Katie's asshole in 'Lick Your Step-Sister's Asshole'. They're all her, all Katie's home movies...WOW!
