I have little cousins who wear XL Boys Pull-ups. I found some at my 
grandparents' house and tried them on for several nights.

I was 12, just about 13. I was staying at my grandparents' house on 
vacation. While putting away my clothes in the dresser, I found some XL 
Pull-ups in a drawer. Later that night, around 11:00, I got up and 
stripped down to my undershirt and boxers. I grabbed a Pull-up from the 
drawer and opened it up. I smelled it and it smelled great! I pulled on 
the pull-up and it actually fit really well. I put my Pj pants back on. 
The Pull-up bulged through my pants a little bit. I got back in my bed 
and started exploring my pull-ups. They were smooth, form fitting, and 
there was a lot of padding. I loved being in the Pull-ups. I went to 
sleep. I slept like a baby! I had never slept as well in my life. The 
comfort I got from wearing the Pull-up was not comparable to anything 
else! I woke up really early, so nobody else was awake. I decided that I 
should use the Pull-up for what it was meant to be used for. I peed in 
it. I couldn't poop because it was too detectable.

I watched the front of the Pull-up bulge out with the fluid in it! This 
made the Pull-up a lot warmer and thicker! I played in my room for a 
while with baby toys in only my pull-up until people would start waking 
up in the house. The next night I put on 3 pull-ups instead of one! This 
was way more bulky and padded. I preferred the multiple pull-ups. They 
bulged out of my pants more. I played around with the baby toys again. 
Then I went to bed in just my pull-up. I slept even better that night 
because I felt way more secure with multiple pull-ups. The next day, I 
found myself alone at the house because everyone else was at the store. 
I put on 3 Pull-ups again. I then had a huge glass of water. I went out 
side to ride my bike. While riding, I could hear the crinkle of the 
pull-ups and see the huge bulge. I then had to pee because of all that 
water I drank. I just let it fly! The pull-ups held everything in and it 
was really warm and getting thicker from the pee! I went back to my room 
and stripped off all of my clothes so I just had on my Pull-ups. I went 
out and watched TV. I peed 2 more times. The pull-ups got super thick 
from the pee. I then got a call from my parents that they were on their 
way home, so I got rid of the evidence. I still wear pull-ups when I go 
to my grandparents house!
