0pm I booked a table for two under Tim’s name.During the coming week I looked at my wardrobe I could hear my late Mother saying “Girl if you like ...he guy and want to see him again dress the best you can, if you don’t like him a sloppy sweater and jeans” So I went shopping for a new dress. shoes and handbag booked to have my hair done Friday lunchtime ,I felt the excitement building during the week even thought I saw Tim every day.After I brought Tim back from school I took a long hot bath. "Thanks, Bro," Anna said, moving over to hug me tightly, resting her head on my shoulder while I held her toward me.I did feel a spark of attraction as I held on to her though, a feeling that I desperately tried to ignore.I released her, and stood up to leave."Sam?" Anna asked, stopping me."Yeah?" I turned around to face her. She was picking at her nails, an uncertain look on her face."Was I... was it good? T-The kissing, I mean," she quickly added, face turning scarlet.That certainly caught me. I would put on really tight shorts, get hard, and then walk infront of them for them to see it. I didn't really know what I was doing but I knew that when I did it my dick would get even harder and start tingling. My bedroom was right next to the bathroom and anyone walking by could see me in my bed. One night when my sister's friend was there I was in bed and was hard as a rock. I wanted her to see my dick so I got on top of the covers in my underwear and tried my best to get her to look. I. I had to rearrange it and that would mean I would have to reach down in my boxer shirts and straighten my cock right behind my sister. All the time I knew that she could feel me change moods and getting a hardon mehind her because it was hitting her in her lower right back. I made as if I was lowering my hands to massage her back lower down as I made my way into my boxer shorts. I remembered again how totally obscene this was, how many countless awkward moments I had experienced with my sister.
