My sister discovered my diapers and rubber pants when I was in my mid 30's and staying with her a few nights while traveling on business. As kids we both wet our beds and mom diapered us. I'm 3 years older than her, and wore diapers until I was 17 while she stopped around the time she started having her periods. So for several years, she saw me in diapers and rubber pants every night and sometime saw mom change me out of my wet diapers in the mornings. But since we were both bedwetters for so long no one in the family thought wearing diapers was a big deal. I finally stopped when I knew I would be leaving home for college. Mom kept encouraging me to stop an=d even promised that I could wear diapers when I came home holidays. Reluctantly, I finally stopped, even though by then I knew I like wearing diapers because diapers hade become my first and only sexual experiences. I used to play with myself under me wet diapers every night. The first time I came home for the holidays, mom asked me if I wanted diapers and I told her I did. She told me all my diapers and rubber pants were still in my dresser and I was welcome to wear if I wanted, but would have to do it myself. For next few years I diapered myself when I was home, but that became less and less often. Of course my sister knew I diapered myself when I was home, since she liked to hear all about college and we would chat well into the night in my room. By then I had diapered myself and we just talk like the old days with me in my diapers and rubber pants. Sometimes I even went potty while we were talking. She did ask me a few times why I still wore them and I confessed that I felt happier and more secure in diapers. As the years flew by I came home less and less often, wore diapers less and less and they assumed I had finally grown out of it. Secretly,. however, I knew I still wanted diapers but felt I needed to keep it secret.
Fast track 15 years or so and my career is flourishing, I'm quite successful and considered a leader in my profession, my family is very proud of me and look up to me for advice and support. But the more successful I am, the more I want to wear diapers and rubber pants and wet and mess in them and the more fearful I am that someone might discover my infantile behavior and embarrass or humiliate me and make me a subject of public ridicule. So it remained my deep, dark secret even though I was wearing as often as I could. My family of course had no idea and I was sure I would be deeply ashamed if they found out.
I called my sister, told her I was traveling on business, had a client who lived in her town and would love to stay with her for a few nights. She was so excited since it had been as few years since last saw each other. I stopped by her home to drop my bags off and to hug and kiss each other before meeting with my clients. I returned later to have dinner with my sister and catch up with each others lives. As I came inside, my sister was standing a few feet away, holding my thick diapers and rubber pants I had packed in my bags, something I always did when traveling. My mood quickly changed from excited to fear and shame. She looked at me and said “I thought I could be helpful and unpack your bags for you and I found these. I thought you had long ago stop wearing these, but doesn't look like you did. What happened sweety." I stammered for awhile, so embarrassed knowing my little sister knew. She could see how nervous and ashamed I was so she gently tried to reassure me it was alright, and encouraged me to open up about this. She offered a glass of wine and sit down and talk. I felt somewhat better, sat on her couch, and took a glass of wine to settle my nerves. “Sweety, you know you can be honest with me about your diapers. After all, we used stay up all night when you came home for the holidays and you'd have your diapers and rubber pants on. I even had to change you a few times before we went to bed, you had gone potty while we were talking, remember?” I nodded my head yes and started to tell her all about my life long desire to wear diapers but kept it a secret from everyone including mom and her. I wanted everyone to believe I had finally outgrown diapers and wetting and was just a normal guy. My sister told me neither she or mom would think any less of me because I still liked diapers and that I should open up with her and tell her all about it so she could understand. My sister had been a psych major in college so she asked the inevitable question “Do you get off wearing diapers? Is it a sexual thing for you? Is that why you never date girls? Please sweety, help me understand.” I nodded my head yes and told her all about how I used to play with myself all the time after mom had pinned my diapers on for the night and good it felt to make myself cum in the morning when my diapers were so wet, racing to cum before mom unpinned my diapers and dressed me for school. I went to tell I never really stopped wearing diapers and still play with myself whenever I can wear diapers. And how afraid I am about dating girls who might find out about my fetish. I just felt I couldn't risk anyone knowing. My sister told me “You're right that most girls would shy away from that, but many wouldn't and you need to start opening up with girls you might be attracted to. You're missing an important part of living by not having loving sexual relationships. I hope we continue talking about this tonight. Dinner should be ready soon. Now be honest, would you like to pin your diapers on now? I think you would be so much more comfortable if you did." I look at her somewhat shamefaced, so she takes my hand, helps me up and takes me to the bedroom, with my diapers and rubber pants in her hand. “Where are your diaper pins honey? Did you bring any baby powder? Oh here they are. Do you mind if I help diaper you? I'd love to and must be 15 years since I last pinned diapers on you. Take your trousers off, lay down on the bed and let me take care of you.” I take my trousers and dress shirt off and lay down on the bed. She looks at me and “off with undies." I do as she commands while she folds my diapers just like mom did, sprinkles powder on my pee-pee and bottom and starts to pin my diapers on but tells me “I can see how aroused you are. Are you always like this when you pin your diapers on. Mom told me a long time ago that you would get a hard on when she diapered you. I think she thought it was cute. Plus your manhood is nothing to be ashamed of. Most girls would love to play with it.” Finally she pins my diapers on, pulls my rubber pant over my diapers and tells me dinner is almost ready and to throw a shirt on, but otherwise she's fine with wearing just my diapers and rubber pants like both of us when we were kids. I have to admit how good I felt wearing my diapers so freely and openly. We walked to the kitchen together and as I finished he glass off wine, I felt myself trickling potty in my diapers. I felt so secure and happy.
