I'm watching some hot step-porn on my phone thinking I might head to y room when my stepsister Destiny comes up wearing tiny panties and a thin top. She's mad that I don't apy attention to her and instead watch porn about what we could REALLY be doing. She's confident she's sexier than the girls I am jacking off too. I had no idea she wanted to actually fuck. I always thought she was just kind of a cock tease that liked attention but she proves she is serious
