My little sister called me in to "show me something", she opens the door and she's wearing lingerie with a little bunny tail, asking me if it's cute enough for the booty call she lined up while we're back at home. Fuck yeah it is, and I had to shoot my shot so I asked her if she wanted to play more truth or dare before her date. I think that's what she was hoping for showing me her body like that. First dare "get naked". Next dare "let me see your dick" she says. Then my own sister with very little prodding is stroking my cock. Dude it was crazy but it felt so good, and she was clearly into it. And then she wanted me to cum for her so she stroked me to completion and I think I came the biggest load of my life. She was astonished. I hope she washes her hands before her date. Slut.
