I was 7 years old; my nephew was 3 years old. Every morning it was the 
same routine. Both Justin (my nephew) and I used to get up early and 
watch TV until my sister woke up.

I was usually first to get up, then Justin would follow me shortly.

I would go downstairs in our playroom to watch TV while sitting in this 
big recliner.

Justin still in his very soggy, wet night diapers, (his night diapers 
consisted of 1 disposable diaper which was the older flat style 
Pampers, they had just come out with the tapes, then 2 cloth diapers, 
and another Pampers disposable diaper, and finally plastic pants.

He had just started potty training, he was totally aware of what he was 
doing and didn't like to poop in the potty. He preferred to hold in his 
poop until he had his night diapers on.

He would follow me down the stairs waddling in his thick bulky diapers. 
I would walk over to the recliner, but Justin always hesitated as was 
his routine. He would stop at the bottom of the stairs, squat a little 
bit, grunt, push and his face would turn really red as he pooped and 
peed in his diapers.

I used to love watching him do this and I would always get a hard on. 
He never saw me watching him so there was no pressure on him. I would 
rub my penis while I watched him grunt and fill his diapers. I could 
actually hear the poopy pushing its way into his diapers with a series 
of little farts. Then he would straighten up and grab the front of his 
diapers while he finished peeing.

Then he would waddle over to the recliner and sit in between my legs.

We would watch TV for a couple of minutes, the whole time my penis was 
throbbing. I could smell the stink of his dirty diapers and this 
aroused me. After a little while I would reach between his legs really 
deep into his crotch and squish the poopy in his diapers. I would 
squish the poopy in between his legs, (he usually had a big mushy 
load), and rub it all over his privates. I could feel the poopy 
squishing between his legs. I would push and squeeze and rub his poopy 
all over his penis and testicles. He would just sit still with a hard 
on enjoying every second. His face would be all red. He liked when I 
called him stinky pants. He would get even harder when I would say 
"shame on you doing poopy and pee pee in diapers". He loved having wet, 
stinky diapers.

Justin was a diaper squisher on his own as well. I caught him a couple 
of times after he pooped in his diapers. He would squish and squeeze 
the poop all over his butt cheeks and push it between his legs and rub 
it all over his privates.

He would usually look for me after he pooped in his diapers because he 
liked it better when I squished his dirty diapers.

Sometimes I would sleep with him in his room. I would wait for my 
sister to go to bed. Then I would take some of his diapers and diaper 
myself. I would put on 3 of disposable diapers and a pair of his 
plastic pants and get in bed with him. I loved the feel of the thick 
diapers between my legs. Sometimes when I was brave enough I would poop 
and pee in them, also. I used to talk Justin into pooping and peeing in 
his diapers by pooping and peeing in mine. I would get up on my knees 
in bed and start grunting and pushing and soon felt the poopy pushing 
it's way into my snug diapers, I would get so aroused and stiff. Then I 
would say to Justin "your turn", Then he would get on his hands and 
knees, grunt a little, push and as usual a couple of little farts 
followed by the sound of the poop pushing it's way into his diapers. We 
would rub and squeeze each others wet poopy diapers. Eventually he 
would fall asleep and all night long all I did was put my face in his 
stinky crotch while lying on my stomach masturbating in my diapers. I 
would have to get up early to clean myself up and throw away my dirty 
diapers. Justin ended up not being potty trained until he was 5 years 
old! He absolutely loved wet, stinky diapers. I always wondered if it 
was because of what we did with each other. Did I delay his potty 
training?

He remembers those times and we still from time to time sleep with each 
other wearing wet poopy diapers. We still squish and squeeze each 
others dirty diapers. He is 40 now and I am 44.
