My stepsister is a carefree slut! And she has insatiable sex drive! She doesn't care where I am or what I'm doing. For sex, she'll come anytime, anywhere, with her unstoppable lust, and just insert herself and cum over and over! Once she's satisfied, she goes somewhere else, then comes back when she wants to fuck again, repeating the insertion! The continuous selfish insertions are too much! It's exhausting! But it feels incredibly good, so I can't refuse. I have some responsibility in this too.
