A few months ago, I decided to lock my naughty step daughter, Ella, in a chastity belt because she is a chronic masturbator. One day after school, I found her frustratingly humping her covered cunt on anything she could find. I knew it was time to use humiliation to deter her from her sinful ways- like any good Mommy would! Ella humped every pillow on her bed before I allowed her to remove the belt. Upon removing the chastity belt, I inspected my step daughter's cunt- boy, was it red! Despite her princess parts being swollen, Ella's desire to cum for Mommy doesn't subside. Ella finishes by roughly humping her fluffy pillows into an orgasm before I lock her back in chastity and take away the keys. No daughter of mine will touch herself without loving parental supervision
