My mom always had me wear diapers and rubber pants when she took us to the movies, both drive ins and theaters. I was a bedwetter until my late teens, my sister had similiar problems although not as long, so she diapered both of us before we went out. In those days, they often had double features and along with previews of coming attractions and maybe a cartoon or two, we'd be there for several hours. Mom didn't want to mess with taking us to the restroom multiple times, so she diapered us instead. We'd end up with pretty soaked diapers by the time we left for home. Later I developed an attraction to wearing diapers and rubber pants even though I didn't wet my bed anymore. When I left home for good, I wore diapers off and on, mostly weekends for fun, pleasure and all and when I went to a movies I always wore diapers and rubber pants and left soaked. That was also when I first saw adult movies, something I hadn't experienced before. The first time I went to one of those theaters, I wore my usual diapers, and at one point during the movies I got pretty horny watching pretty girls and not only went potty, but also played with myself under my wet diapers and ejaculated. I felt safe doing this since there weren't many guys in the theater, and I was able to sit far from others. At this point I had virtually no experience with girls other than my sister growing up, so watching an adult movie was so arousing and exciting it enhanced the experience of wearkng diapers, going potty in them and then playing with my pp all the more intense. The next time I went, I ended up not only going potty, playing with myself but also went poo poo in my diapers watching the show. Now this was incredible since up to now I rarely messed in my diapers, it was just something I wasn't supposed to do. That afternoon, my arousal and ejaculation was more intense than ever, and I ended up frequenting adult movies often and usually messed myself.
That was a long time ago. Now my wife and I love to spend a couple of hours cuddling on the couch watching a movies or streaming a series or two before going to bed. I am always fully diapered with her, a blanket over us to keep us warm, and go potty once or twice while sipping a glass of wine. I don't need to play with myself like in the old days, my wife instead likes to do her little diaper checks, put her hand down the front of my diapers and play with me a little. By the end, it will soon be time for bed and my diaper change, but before that, my wife will open her blouse, remove one breast from under her bra for me to suckle. We've been doing this for so long now, she doesn't lactate anymore, she used to when our daughter was little, but doesn't matter, I love sucklking her breast and nipple and she loves to mother me. \
Btw, I don't think Horsecat would ever spank her naughty boy, she would find another solution.
