My sister and I have been sharing our house since my wife died 9 years ago. Somehow last year my sisters best friend Laurie talked my sister into allowing Emily to move in with us. Emily is Laurie's youngest daughter who caused her many problems over the years. She is 23, has been off drugs for a few years, and although she tries has a hard time getting a good job because of her police records. I'm 65 and retired while my sister still works 5 days a week. I do golf a couple times a week but I am also home during the day more often then not. Emily works at a supermarket usually two to four days or nights a week so I am at home with her frequently. I quess I should say something to my sister about this but I have yet to tell anyone. Emily is a very pretty girl and I'm not sure why but she has no sense of modesty. It never happens when my sister is home but I estimate that I see Emily naked at least several times a week. Aside from that she sunbathes in a bikini often and the clothes or lack of clothes she wears around the house are skimpy to say the least. I do have a girlfriend my age and I am still able to have s** but I also m********* often during the week. Some of the pajamas or night clothes Emily wears are close to transparrent not to mention how she often goes about with only a towel around her. Her bedroom door is open most of the day and when she exits the bathroom before and after a shower she is naked most of the time. Back when she first moved in it didn't happen as often but the longer she is here the more I see her in different stages of dress. Naturally I suspect she does this intentionally but don't know why she would parade around like that in front of an old man like me. If we have company or if her friends or boyfriend are here she is dressed properly. When its only me and her in the house she always wears something incredibly revealing or just showers and goes around with only the towel. I never say anything to her about it and intentionally sit in my bedroom when I know she is going to shower. The door I leave open a few inches and she normally goes into the bathroom naked and comes out the same way going back to her room. When she goes into her bedroom she never closes the door and I sit watching her dry herself and put on whatever she wears that day. I often stand at my door and m********* as I watch her and a number of times I am sure she knew I was watching her. I even try to pretend her nudity around me doesn't bother me but am sure by now she knows it does. When she is in a towel I think she comes into the kitchen or livingroom to expose herself to me. Just by the way she leans over or sits down her rear and v***** are exposed. She arouses me almost every week day and I must admit I like her living here now which I was apposed to when she first moved in.
