When my little sister told me she had never had anal sex but wanted to try it, I was in disbelief and turned on that she asked for my help.
While I sat there and told her I would find a guy to help us my panties were getting soaked!
I told her that I was going to fuck her ass with my fingers for a couple nights and get her used to having something in her ass.
The next couple of days after that I would fuck her with a small dildo and then the big day would come.
My friend would come over and I would me right there to hold her hand as the first cock ever invaded her tight brown hole.
True to my word, I sat in front of her fingers in my pussy, getting off as I watched her take her first dick up the ass.
