It happened again
I woke up this morning in the middle of pooping in my diaper. My diaper was already wet and I had already dropped a sizeable load in the seat of it by the time I woke up. So I continued pooping until I was empty then I flooded it and at this point it started leaking (thankfully I have a mattress protector on my bed for just such an occasion) so I simply relaxed and enjoyed the sensation of my completely full and soaked diaper.
