Annoying stepsister while online shopping

He found her as usual, on the bed without taking the screen off her screen, he didn't even know how many times he had asked her to stop playing and pay attention to him. But she didn't respond, all her attention was focused on online shopping and she barely noticed. So he decided to teach her a lesson. She was wearing a small pair of shorts so he took the opportunity to start caressing her legs, going up little by little until he reached her slit and touched her shamelessly. The girl barely moved, but showed neither discomfort nor pleasure. He pulled down his pants and pushed his penis deep inside her.
