Stepbrother's voyeuristic behavior leads to sexual encounter with stepsister

Stepbrother was in the house alone with stepsister and as he was walking around, he saw her playing with herself in the mirror. As he was watching her, she noticed him and at first she was very upset about it. But after a short talk with him, she decided to have sex with him. So, they went upstairs to the room of stepbrother and as soon as they were alone, she started sucking his dick. Then he fucked her hard as she was moaning from pleasure. After that, she took off her clothes and spread her legs as wide as it possible to let him fuck her pussy. Then she took out her dildo and put it into her pussy to make it wetter. Then he continued fucking her, but this time in her asshole. After that, he fucked her again in the pussy, but this time much harder than before.
