My Girlfriends Younger s****r by loyalsock

It has been awhile since I have had a really great sexual experience. I do have a steady girlfriend but she is the type of girl who will have sex but does not like it that much. It is not my fault, she just has some motional problems and is not a very sexual person. Don't get me wrong, she is an extremely beautiful girl with golden blonde hair and an amazingly fit body. She is also great to be with but sexually, she is very frustrating. I have been with her for almost two years and have got to know her mother and 18 year old s****r very well. In fact her s****r, Jaime, says she is totally comfortable with me, like a b*****r. I know this is true because of the way she walks around the house in her swimsuit without caring that I am there. (Most girls are very self conscious of their body at that age.) It is hard for me to be just as comfortable when she does this because her thong bikini is very revealing. This wouldn't matter much if she didn't have a gorgeous body. But she does. She is about 5'8" and 115 pounds. She has the most perfect long blonde hair and amazing tanned legs. They are so long that I can imagine the way the would wrap around me. Of course she doesn't help my sexual frustration when she wears the tiniest shorts that just barely show her lower butt cheeks. This girl has got to be perfect. Over the last year I have spied on her while she watches T.V. on the couch with her legs spread open and her panties showing through the sides of her shorts. I knew that she ...

... was a very sexual 18 year old when she casually asked me one day why she had some very erotic dreams about a guy from her school. Once when I was sick, I fell asl**p at my girlfriends house. The door was open in my girlfriends room and Jaime had just finished taking a shower. She knew I was in the next room but thought that I was still asl**p. She walked past the room topless and I caught a glimpse of her perfectly rounded firm breasts. I had always imagined that they would be great to grab a hold of and cum all over. Although I was sick, I still managed to grab a hold of my bulging cock as I came all over my girlfriends bed. On another day I sat with my girlfriend on the couch and her s****r was laying on the floor. I peeked out of the corner of my eye at Jaime's perfect ass that always gets me hard. It is the type of ass that is not big but not so small that is doesn't show through her short jean shorts. I always dream of fucking her from behind. She then got up to go to the bathroom. From where I was sitting, I could barely see the door of the bathroom around the hallway corner. Jaime must not have noticed this because she left the bathroom door open as she sat down on the toilet. She must have thought that I was not going to get up and that I could not see her. I didn't want her to think that I was watching so I kept my head pointed towards the T.V. but stared with all my might out of the corner of my eye as she finished up. I thought this was great but my dick stiffened ...
