Step-sis avoids chores and seduces step-brother for sexual pleasure, resulting in internal ejaculation

My stepsis was supposed to fold the laundry, but she got bored and wanted to have some fun instead. She came up to my room and started dancing on the bed, and then we had sex. At first, I wasn\'t into it because she\'s my stepsis, but then I got really horny and I fucked her hard.
