#72963 - I know I shouldn’t be paying too much attention to her because she is technically my sister, but what the hell; she is so hot it would be a crime not to notice. I knew she was telling me how to do the question but I couldn’t take my eyes off of her nipple which was now starting to harden, I knew that she noticed what I was looking at and seemed to be turned on by it. I was still in shock standing there, thoughts racing through my mind, what just happened, how long was she there, why did she not say anything, and why did she look at my cock before she left? I quickly went to the washroom to clean myself off and retreated to my bedroom, closed the door and just laid on my bed for a while thinking about what just happened.
