Pissy diaper worship
Bed is covered deep with a couple week's worth of pissy diapers. I rub my face into them and inhale the stink. Then, I put the ripest diaper I have over my head, and strap it tight over my face, blinding me and enveloping my head in a pissy diaper hood. I lay down on the bed, and enjoy the feeling of cool stale piss soaking through my t-shirt, and I finish by playing with myself in & out of the thick pissy diaper that I'm wearing.
