I knew all about my sister's dirty little secret, and I know exactly how to use it to my advantage. I pull down her shirt after she gets off the phone with dad. "What are you doing!?" She tries to act angry, but Demi is a huge slut for a good cock! Watch as my younger sister gives me the sloppiest blowjob. She goes down on me, throat fucking my throbbing cock. She turns around and rides me, with her ass bouncing up and down, it was hard not to cum too quck. I take control and give her pussy the best pounding she's ever had! I pull my cock out of her tight cunt and blow my load into her pretty mouth.
