Teasing My Shy Stepsister Into a Sensitive Nymphomaniac

Synopsis

After my parents remarry, I gain an adorable and extremely shy stepsister who goes braless around the house. I start repeatedly sexually harassing her by touching her exposed nipples every day, and she accepts it. Despite initially resisting, my stepsister becomes increasingly sensitive through continued nipple stimulation—both over and under her clothes. She’s completely trained into a hypersensitive, premature girl who drools from pleasure! The once-innocent stepsister transforms into a lewd woman who climaxes shamelessly and eventually begs me to touch her. We engage in endless sexual encounters with my stepsister climaxing vulgarly over and over.
