Teaching My Slutty Stepsister a Lesson with a Vibrator

My 18-year-old stepsister, Serena Sterling, loves to dress like a slut, showing off her perky tits and round ass. I decided to teach her a lesson by inviting my friend Jay Rock over, who's known for his bedroom skills. I handed him a small vibrator and told him to use it to teach her respect. She sat on the couch, her skirt riding up, as Jay leaned in, whispering in her ear, and turned on the toy, making her shiver with anticipation.
