Fucking my horny stepsister and filling her with semen

My stepsister is a sexy blonde who is so kinky that she loves to fuck her boyfriend and me. She gets turned on when I have a hard-on, and I love the way her pussy feels around my cock. This morning she woke up with a huge hard-on and told me she wanted to have some fun. I took her back to my room, where we fucked all day long. 

"I love you," she said, "and I'm going to make you feel like the king of kings." "I want your cum inside me," she said. "Then cum inside me," I said. And she did.

She came so many times that I filled her up with my hot cum.
