Fucking her stepbrother instead of cleaning!

It was a great weekend day – the sun was shining and I was getting ready to go out and do my thing. I noticed my stepsister, crawling around in the kitchen, cleaning the floor. “What’s up, stepsis? Aren’t you supposed to be at a party?”, I asked. “Exactly!”, she responded angrily, “the parents f***d me to clean the house instead and now I have to stay in instead of having fun! I hate you all so much!” “Well, there’s no need to be rude. I also clean the house from time to time! Alright, I gotta go, you have fun with your mop!” The sister stopped me – “Listen, honey… I want you to help me and I’m willing to pay for it!” “Pay? I’ve got a better idea, my sweet stepsis! I wanna fuck you…”
