Ngentot untuk diam-diam, saudara tiri mendapat tawaran yang nggak bisa dia menolak

Cindy, my stupid step-sister, was in my room without my permission, I kicked her out but she forgot her phone, so I took it and found she's such a slutty teen! So I told her that she didn't want me to show the pics to our parents, she'll have to fuck me really good periodically! She did and I think she will do it again gladly because she kinda liked getting fucked hard by her stepbrother
