This weekend my sister was in town so we could visit our mom together. We have the same mom but different dads, and she stays out of town closer to school most of the time. Anyway afterward she was going to drive back but I offered for her to stay at my place so she didnt have to drive so far. She said yes and we both headed over.
We each showered in seperate bathrooms. I forgot to grab clothes from my room but I figured I would be far enough ahead of her to go grab some before she got out. Right as I dropped my towel to start putting my boxers on, I looked up and she was standing there with her head out of the bathroom door. I tried to slip my boxers on quick but she had already clearly seen and seemed like she was looking before I saw her. I just did an awkward laugh and said oops sorry. She just gave me and mmmhhhm and smirked. She was asking me for an extra towel and when I handed it to her she let the door open more and I got a peak of her whole body in the mirror, she looked amazing, such a sexy figure and one of the most perfect asses I have ever seen.
