Well, making short a long story, my mother decided to buy a belt to make spicy my parents' marriage.
They were evolving until a totally serious usage, and my mother discovered that belt made happier as woman than in any moment of her life.
So when after my brother, they had the girls, she proposed the usage.
And well... We are 3 happy daughters, 2 with belt and another without it.
She is losing it 😆
