I moved in with my stepdaughter from my second marriage. My cool eldest daughter teases me with her panties and grabs my dick, saying, "You sure you don't have your dick hard, do you?" She pretends to be cool, but she gets excited eavesdropping on my nightlife with my wife. She peeks at me having sex with my sister and gets her pussy hot. She gets excited when she sees my erect dick while cleaning the bath. I suddenly come into her room while she's masturbating with a vibrator and push her down, and she pretends to hate it, but gets really excited. She's never seen such a big dick before, but she sucks it, making a dirty noise. And she cums over and over again during sex, making her the ultimate tsundere little devil.
