I was a pretty normal guy. 28, straight-ish, but kinky, and occasionally liking a bit of dick.
I’d met up with a few guys over the years, but I had a whole new fantasy to play out, and this time it was someone much older. He told me he was about 50, maybe 52, but never really expanded. His cock looked perfect for me, and the first few times we met it seemed pretty normal. I’d suck him off, and he’d cum in my throat and tell me I was such a good boy.
Then, he asked me to wear diapers the next time we met. I was a bit weirded out, but something in the back of my head told me I wanted to be his Good Boy, so I did. This time, though, we just hung out; or so I thought. I kept drinking water, the only beverage available, and eventually became desperate for the toilet. He kept telling me to just hold it, to just stay sat there and he’d take me to the toilet in a minute, until finally I couldn’t. At the time, I was ashamed, I pissed myself in front of Mike, and all I’d wanted was to be his good boy.
He kissed me on the forehead, and asked about my accident. Taking me to what I thought was the bathroom, he told me to strip. I took my clothes off, and stood in front of him in just a diaper, ashamed and blushing. He moved me, gently, into a fully kitted-out changing room. I nearly panicked, but his calm voice kept telling me it was okay, and that I just needed to change. The diaper came off while I was lay on my back, and his soft hands cleaned me up. Then a fresh one was fitted, and I was allowed to sit back up.
“It’s okay, boy, I’ve got some clean clothes here for you,” I relaxed slightly, “just while I wash those dirty ones.” He presented me with an adult-sized babygrow. My eyes must have shown him the shock, “it’s okay baby boy, you need to be all dressed before we go back through!” The brightness in his tone shocked me, and I dressed. He guided me back through to the living room, and sat me on his lap on the couch. A kiss touched my forehead, and I relaxed into his arms.
We ate together, and then he put me to bed for the night. His logic was that my clothes still weren’t dry, so I couldn’t exactly leave, and I agreed.
The next day, I woke up to a wet diaper again. He came in, fussing all over me, telling me that good little boys don’t wet their diapers, and took me to get changed. I was still groggy from the night before, when I realized that this time my legs were tied to a pair of stirrups.
“What.. wha are you doing?” The words tasted strange in my mouth,
“It’s okay Little One, I’m just getting rid of all this nasty hair. Little boys aren’t hairy, are they?”
I couldn’t disagree, but then I felt my arms being tied down as well. The combination of Nair and razors crossed my skin, until finally he was satisfied. “Look at you! You’re so cute!” He kissed my forehead again, and fondled my limp cock, “but this little hole,” his fingers touched my asshole, “it needs filling!” Still with that bright tone, but now he pushed lube inside me, then stretched me with something I couldn’t see.
“A cute little buttplug for my cute little boy!”, then came the diaper again, and this time I was collared before I was released. When I looked in the mirror, I saw it was a cute pink collar with a padlock holding it closed. I looked over at him, and he smiled. “Time to get dressed!”
The babygrow fitted over me once more, and he took me back to the living room.
The next few weeks, I slowly lost any form of independence that I’d had. I became His Little Boy, and I existed for him to play with. Slowly but surely, he began to modify my body – I learned he was feeding me estrogen, and my body became softer and the hair stopped growing back. Both of my nipples were pierced, and my cock was locked permanently in chastity.
Slowly but surely, I came to think of myself as his Little Boy, and couldn’t act on my own. He woke me up, he dressed me, he changed me, he fed me and he washed me. I don’t remember how it all started; but now, I’m His.
