My sister was watching me for two weeks and well as my baby sister. She is twenty one and I am seventeen. So I was joking around and said that I would love to be a baby because she slept all day. Well I got in trouble in school that day for something stupid and had to come pick me up. She told me I was childish and pathetic. So the next day she took all my underwear out of my room. There was only a diaper on the shelf. I didn't want to go get her and ask her where it went, considering how angry she was. I was about to go without undies until I rethought the possible consequences. I thought for the heck of it I tried on the diaper, even though I could have gone without underwear, I went to school with the diaper. I know, bad idea. Especially since I forgot I had gym that day. I forgot I was wearing the diaper, although it was really tight. I pulled down my pants and my friends had already since the Princess Nappy. Then I was wet the rest of the day, and of course got into trouble again was sent home. Now my sister, Jenn was pissed. Jenn yelled at me. She asked why I wet myself and I said I didn't, but it didn't help. The next day there was only a diaper in my underwear drawer and I told Jenn I was sick. She was a medical student, which in the spur of the moment I forgot. Since she was still mad she said if I was serious and I of course said yes. She mad e me lie on my back which I didn't get until she brought in my little sisters baby thermometer, the most accurate thermometer. She shoved it up my butt, annoyingly as it was. And dam it hurt. She actually said I was feverish and let me stay home. She said she was glad I wanted to be a baby, considering I was one. I didn't know what she meant, until she showed me. She stripped me down and I being the feeble lady I was she did it easily. Then she forced me into a warm bath. She yelled at me that I was disgusting. I told her I could shower if she left, but she told me I might drown. Then she pinched my cheek. She washed me up next. When i got out my thing was so small. She commented that it was smaller than the dummy in her pre- med class. I told her to knock it off and she gasped and took me to the doctor. In her red convertable. In my baby sister's spare carseat. The doctor said I was overdue for a certain shot and Jenn told them I should get it in the butt so it would hurt less. The nurse did comment on her knowlegde of medicine from her class. After the shot that hurt like hell she dragged me home and shoved me into the baby's crib. She told me it was bedtime and that the baby, Lily would sleep with Jen. She stripped me down to a diaper and tied me to it. I figured I would just do it. Little did I know that she invited my friends about half of them girls over and they show me in the crib. They woke me up and laughed. My sister until this day says she will post the pictures on the internet if I tell.
