My precious underwear

What type of underwear?

I was at someone's house not quite sure who's but they had a 6 year old kid. I remember we slept in the same bed she wore pull-ups to sleep. I think I asked her why and I just remember I upset her.
I didn't mean too, I remember my mom bring me in the other room to tell me to not to tease her for wearing diapers.
I wasn't going to tease her at all because I was curious why she had to wear diapers to sleep. But it was late like 10ish maybe so we were supposed to be asleep already so we went to bed.
I remember wake up hearing crying and heard something about I didn't take it off when I looked down. I was wet I peed the bed. I know I did because It was wet all around my crotch.
I yelled for my mom I told her I peed in the bed. She said no honey y... I lifted the blankets I said I didn't mean too.
I got up and my mom got my bath ready, helped me a little bit then left me in the bath, while my mom helped get the sheets cleaned. The girls mom cleaned her up in the upstairs bathroom. I got cleaned up etc.
I was like washing my self and I looked over at the sink. Her pull-ups were right their on the sink counter at that age curiosity is a thing you can't resist. I felt like even though like 6 or something years ago I was in pull-ups I feel like I've never seen them before. I got out the tub quietly ran over to the door locked it. I was about to take one out of the bag until I hear steps and ran jumped back in the bath. I forgot to unlock the door and she was banging on the door telling me it's jammed. I told her its locked you must've hit it over by accident.

The lock was a hook lock so it's chancable if that's even a word. Because at my old house I did it twice. we had to take the door knob off and get a hanger and push it up then we changed the lock thing.

But anyway I got out unlocked it. My mom told me to get dressed she gave me some clothes. and I put them on my mom came back 1 minute later. She closed the door behind her and told me can you do something for mommy, she told me to take my pants off. I think I knew why but for a different reason. I thought since I wet the bed she was going to put a pull up on me. but no it was because she wanted me to do it so it would make the little girl feel better. so I said yeah. Holding back my smile.
