American Dad: The Cuck of Langley. (Private with Firedreake19)
 

Stan Smith was quite a stubborn, selfish, and mean man. Everyone in his neighborhood new it, even married couple Greg and Terry. They invited Stan over for an evening of sports watching. Little did Stan know they were going to teach him a lesson for being so awful.

Stan was by no means a good man forcing his ideas on others, not caring about others and doing whatever he wanted really. He didnt have very much beef with his gay neighbors and figured the two wanted to hang around the amazingness that was himself. So there he was.

The gay couple let Stan into their house. He was only inside for a few moments before getting his mouth and nose covered with a chloroform soaked rag.

The handsome man had his eyes open in shock as the cloth was forced over his mouth. He went unconscious in seconds going limp and falling to the floor. Another reason that Stan had come was that perhaps some part of Stan was rather gay and he couldn't deny that Greg and Terry were rather attractive.

Stan was dragged to the basement where a bdsm dungeon was located. He was stripped naked, locked in a metal chastity cage, thickly diapered, collared, put in locking mittens and locked in a bdsm dog cage. Both Greg and Terry were very proud of their work and teamwork so far on this.

(Is it cool if this leans more towards abdl?)
Stan would be knocked out for at least two hours giving Greg and Terry plenty of time to do whatever they wanted to Stan. Stan looked like he was sleeping like a peaceful baby by the time they finished dressing him. When he awoke he yawned looking around very confused.

(sure)
As Stan slept, Greg and Terry rearranged the dungeon to be a fully stocked Nursery. It was full of bright colors, baby themed decorations and furniture and a fully stocked wardrobe and changing table. "Do you know why you are here Stan?" Greg asked.

(Should Stan maybe be a baby girl sometimes or just their cucked baby boy?)
Stan the nursery was everything an adult baby could possibly want or need. The nursery was full of frills being a light blue color. There was a cute baby cradle just stans size and plenty of diapers to last for a long time. Stan was very much confused not even feeling that his cock had been caged yet. "Greg? Let me out of here.!" He demanded once he knew his surroundings and was ready to beat the two.

"Stan we are sick and tired of how toxic you are! Me and Terry are here to put you in your place and teach you a lesson. And you are NOT leaving here until you do!" Greg said sternly. (Sometimes he should be a sissy, but a majority of the time he is a boy)

"Fuck you! Let me out before I beat both of you." Stan threatened tugging at the door of the cage he was in uselessly. Stan was still pretty strong but little did he know that Greg and Terry had some drugs that would easily take care of his strength and leave him a helpless infant.(Cool cool)
