.. well ... well ... Oh, damn! I can't say it!" She flushed and looked down again.I said, "Did you come to apologize?"Her head came up sharply, an ang...y look on her face. Her intention was clearly to rebuke me, but she stopped short when she saw my expression. She became uncertain, and paused before beginning, "Well, no. I mean, I didn't think I did anything to apologize for." You said I was crazy, and that you were sorry that you had even thought of having sex with me." Oh, that. Well, umm, I. “Oh sweetheart, that was so good” she murmured. “Just like a dog?” I asked. “Don’t be disgusting” she said and gave me a huge grin. Yes, she was thinking it too.I asked her to show me the sites she had been looking at. She knew them off by heart. She seemed to get excited at the rough sex sites, which shocked me. But when she went on a bestiality site she began to breath deeper and it was obviously turning her on. I asked what the attraction was and she said the fact that the dog was in control. "Um, Mo, I really hate to tell you, but you are naked," I said."I know, I figured why bother with getting dressed just to strip when I get to school. Going naked is so much easier," Mo said."Whatever; just make sure you take clothes. We might want to go somewhere after school. That is unless you're going to just stay naked all the time," I said, thinking that my sister may have a pretty good idea.We ate breakfast, cleaned up the kitchen, and left for school. Mo slouched in her seat while JR. I grabbed my stuff and jumped into the shower. I was running my head under the showerhead when I caught a glimpse of Shelly in the mirror. I didn't jump or even make a sign that I had seen her, surly she was just passing the door that’s why I saw her. I lifted my head and had another sneaky look; sure enough she was definitely peeking into the bathroom where I was completely naked. I have never seen my self as an exhibitionist but I found my cock getting hard the fact someone was watching me,.
