I am fascinated by the story.
I've always had a very similar idea.
in which a husband buys a realistic sex doll costume with huge breasts and a very hot figure for his wife.
The purpose of this costume is to ask his wife to wear it for a night of sex.
But while waiting for his wife to wear the costume, the husband gets bored and while killing time decides to take a closer look at the costume.
causing the husband to undress out of curiosity and before handing over the costume to his wife he decides to wear it just for fun.
But by doing so without realizing it, little by little the opening he entered begins to close.
causing him to panic and get trapped until his wife arrives.
Hours later the wife arrives home. to find a very hot realistic doll a few steps from her room.
She then takes the doll, which by then had completed the changes, and returns it to her room where she will have fun with it.
All this because when she saw the doll with the huge breasts on the floor, she mistook it for a gift from her husband.
All this without having the slightest idea that he was really her beloved husband.
