He has fun playing their big daddy, and gives them toys to play with. While two of the adult baby girls are playing, he seduces the third and fucks her, coming all over her face.
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.
While vacationing on Topsail Island last month, I refused to wear diapers on the beach and ended up regretting that due to not one but two accidents. However, every second that I was on the road, in a souvenir shop, buying gas, I was diapered.
