A male student has three girls come to his place after school, after making the girls believe he will spend the weekend doing their homework.
While everyone is taking out books, he is getting his book ready, a book hypnotic regression, and the fun begins.
He plays big daddy, giving them toys to play with, and while two of them are playing, he fucks one.
The following day, all three adult baby girls are now also wearing diapers, and while preparing them for a day of fun, he also does a diaper change on one of the girls, and plays with her pussy while the other two watch.
This continues for a few days and nights, as he takes enjoys sex with all three adult baby girls as he wishes, when he wishes, ending finally with all four of them in an adult baby and diaper orgy, with him and the three diaper girls.
I hate clumping which is precisely why the majority of the time I prefer to wear premium adult diapers instead of cheaper made diapers. You probably have noticed clumping before if you wear a lot of store-brand adult diapers. Clumping does eventually happen in premium adult diapers as well but it takes a significantly longer period of time and usually by that time you have probably wet the diaper about 3 times before you even notice any sort of clumping at all.
