Q: Do you like to cum in your diapers?
A: Definitely, YES!
Q: How do you masturbate in your diapers?
A: I lay on my stomach in the prone position, with my right wrist wrapped around my left wrist.
I bear down against the lower knuckle of my left thumb, pushing my knuckle against the base of my penis (against the prostate).
I then start humping against the mattress or floor until I ejaculate.
More often than not (when I am by myself), I typically only wear diapers at night.
I usually wear two tranquility ATN diapers and milky white plastic pants over them.
When I first go to bed, I usually have to pee, so I let go and wet my diapers.
Then I roll over onto my stomach and masturbate while I fantasize my older sister's friends watching me poop as a toddler and repeatedly shaming me for being too old for diapers. Its usually quick, and in less than 3 minutes I ejaculate and fall asleep a happy camper.
The real magic is in the morning when I feel the need to poop.
I get up on my hands and knees in bed like a real toddler, and I begin to grunt with a binky in my mouth.
(I only grunt for the effect as my morning poop is usually effortless).
When I am done pooping and adding more pee to my diapers, I push the palm of my hand into the seat of my messy diapers and rub the poop all over my butt.
II then push a large mass of poop between my legs and squeeze my thighs together very hard forcing the poop up and over my testicles and penis.
Then I lay on my stomach and masturbate pushing the mess all over the shaft of my penis. Since my diapers are kind of thick (2 diapers), the poop acts as a lube on my penis and helps to get the job done faster. (ejaculation). Then its off to the shower for clean up, and to get ready for work.
