When I was married and my wife began pinning me in diapers...the caution being that I was never allowed to unpin or take my own diapers off, I did just that.
I was sitting in my pee soaked diaper, the smell of pee filling my nostrils and making me very horny...She walked in and caught me...I was very soundly spanked and put back in my diapers and plastic panties. My throbbing little boner poking it's little tent in front.
When she tried to calm me and soothe my whimpering she gave me her nipple to nurse on...then pushed my head down between her legs.
I actually got to see it for a few seconds before she pushed my face against her hairy pussy...my hairless little boner was a perfect contrast...I humped when my tongue found her wet hole and that was when if came squirting inside my diapers.
She informed me that diapers were going to be my main attire while at home and there would be no more bed wetting. and no more jerking off without her permission or supervision.
I wet myself just as I was falling asleep. The warmth spreading across my stomach and crotch was somehow soothing and calming.
I learned that the only time I was allowed to cum was in my diapers and with her oversight....rarely did she let me jerk it but when I did oh wow....
I got used to hands free squirts and cumming sometimes even when all that caused it was seeing her naked bottom or fancy panties.
If I was really good, she would unpin my diaper and have me sit on that sopping wet material and jerk of to her supervision. Then back into clean dry diapers until I needed changed again.
