I'm 45 and my girlfriend Marsha whos 48 moved in with me 4 years ago. She's no knock out but is great in bed and the best blow job I will ever have. I live in a big but beat up old farm house (without the farm) about 20 miles outside Dallas. Its on 4 acres so when I get home from work around 3:30pm everyday I'm always filthy dirty. Theres an open shower out back where I strip down and shower, drop my clothes at the washer and rarely put much more on than boxers or a robe and lots of times just stay naked. Marsha is a barmaid at a saloon close to Dallas and works 5 nights a week and leaves about 5pm or sooner. Now, Marsha has a daughter Lily who is now 27 and has been in and out of rehab for the last 6 years. I met her a few times over the years before Masha moved in with me. Lily and Marsha didn't speak to each other for a couple years but in 2011 she was off the drugs and they became closer again. Thats when Marsha kept asking to let Lily move in with us. I kept refusing but after about 6 months of her begging me to, I finally let Lily move in. She only works at a fast food place a few days a week and can't get a decent job because she was in jail a few times, once for selling drugs. Lily is short a little heavy and not nearly as attractive as her mother. To be honest I didn't like her very much at first and I think for that reason I didn't care if she saw me naked or in my boxers or robe. Marsha was upset with me the first time Lily saw me naked out back showering but I just told her to tell her daughter not to look. As often as I am naked around my house I was never into exhibitionism and if friends come over I'm always dressed. Things changed quickly when I began realizing Lily tried to see me naked most of the time. I wear boxers around Lily sometimes and when in my bathrobe I never have anything else on and seldom ever tie it closed. I'm sure Marsha knew and still knows Lily sees me naked or exposed sometimes but now she never says anything about it to me. What Marsha doesn't realize is when she isn't home thats when Lily is around or near me the most. She talks to me more when Marsha is working and I truly believe she likes seeing me naked or with my robe open. Its not like I would or want to have sex with Lily but I began getting erections when she was obviously looking at me naked or stareing at my genitals while in my robe. At first I tried to turn away but after a month or so I just let her see me hard. Funny thing, she has never talked about me being naked around her. She didn't at first but as time went on she comes out back while I am showering and talks to me but only when Marsha is out shopping or has left for work early. When she started doing that I would dry off and just go in the kitchen naked and make a sandwich or get a drink while she sits at the table still talking to me. Marsha doesn't know this and I never tell her. I also never tell Marsha that Lily has her friend Cindy, who she works with, at the house a day or two a week. Cindy is a little 25 year old, ugly, fat girl, who I'm sure Lily brings over just to see me naked. Even though neither of them are good looking I still get erections and don't bother trying to hide it. Cindy started coming to the house well over a year ago and most of the time only saw me in my open robe at first. I just figured whats the difference if she did see me naked so now I am around her the same way as if its only Lily looking at me. Before Lily moved in I never had a need to jerk off because Marsha would take care of that. Now I can't help but jerk off a few times a week still having the same amount of sex with Marsha. It just gets me aroused that Lily and now Cindy see me naked and it seems like they are the ones who actually seek me out. Lily is almost obnoxious about it and even though my bedroom is on the other side of the house she has no problem walking over and looking in my room. Often she just walks in to talk to me mostly about stupid things. I hardly ever shut the bedroom door even when Marsha is home. I think it was last November the first time Lily saw me jerking off in my bed. Since then I know she has watched a number of times but always just peeks in at me. I'm sure Cindy has also watched me jerk off, not that I ever saw her peeking in but theres a loose floor board about 5 feet from my bedroom and I've heard it squeak twice a few times. Thats when I know Lily is headed towards my room. Most of the time I'm just watching tv but once in a while I start jerking off when I hear the board squeak. Lily is bold about all of this because she always just peeks in first and if I'm not jerking off she walks right in to talk to me not careing if Im laying there naked. I don't say anything about it and neither does she and its only small talk mostly about her stupid job. One thing is I'm sure she doesn't do drugs anymore although she does drink beer and has gotten heavier since she first moved in. As immodest as I am, I have never seen Lily naked. I do see her in night clothes but thats about it. Awhile back I snooped around in her room when both she and Marsha were working. Lily has nothing close to a sexy outfit or bathing suit, her bras are mostly white 34B and her panties are not the sexy kind and mostly cotton. The only thing I did see that I never expected, was a dildo in back of her bottom drawer. I'm sure she masturbates and wonder how often because even though she goes out some weekends I know she don't have a boyfriend. I'm possitive she plans on seeing me naked. She knows when I work overtime and by the time I get home Marsha has already left. Once I pull in the driveway and go back to the shower she is sitting on the back step right where the shower is. I just say hi to her then she begins getting into a conversation with me as I get undress and shower while talking to her. Once or twice a month even Cindy is with her so I guess I have turned into an exhibitionst by now. I almost always get a hard on while they watch me shower and when I go inside they still sit at the kitchen table and I'm still naked. I walk around the kitchen making something to eat and sometimes make a sandwich for them and sometimes Lily has already made one for me. You would think my nudity around them would be offensive but its just the opposite. I know Marsha is aware Lily sees me naked sometimes but I'm sure she doesn't know how brazen Lily is or how she plans on seeing me naked as much as she does. If Marsha is home when I get done work Lily is nowhere to be seen. If Lily is on the back step when I get home I know Marsha isn't. Marsha suggested a long time ago that I build an enclosure around the outside shower but I have no intention of doing so. I do at least wear my boxers when Marsha is home but when shes not the most I have on is my robe. I am naked more often now than anytime in my life. Even when I lived alone I was naked a lot but now even more when Marsha isn't here. The odd thing is we all get along well and Marsha seems much happier now that Lily lives with us. I'm sure thats because she knows Lily isn't on the drugs anymore. I know to that Marsha would not be happy if she knew how frequently Lily sees me naked. Especially if she knew Lily sees me with erections and watches me jerk off sometimes. Marsha knows Cindy visits Lily but also don't know how often or that I am also naked in front of her or that they watch me shower out back. I like them seeing me nude and by now I know they like looking at me that way. When Lily is sitting on the step my showers last longer than usual. I've become so anxious to expose myself I put my foot up on the bench to wash between my legs, bending over with my back to her exposing my anus. I do it even when Cindy is here and as I do they just keep talking nonsense to me. Never thought I would ever do this kind of thing but I look forward to it and find it stimulating. Lily or Cindy never say anything to me about my nudity and I always wonder if it excites them or if it arouses them at all. I guess I'll never know.
