There could be stories where the saree is used symbolically in relation to breastmilk. Maybe in a story a saree is given as a gift to a new mother, and it becomes a part of the journey of her breastfeeding. The saree might be associated with the mother's love and the nourishment she provides through her breastmilk. It represents the connection between the mother's traditional clothing and her role as a nurturer.
In Indian culture, there may be a belief that the fabric of the saree and the act of breastfeeding are both acts of purity. The saree, as a traditional garment, and breastmilk, as a source of nourishment, are both considered sacred. The saree might be seen as a covering that protects the mother - child relationship during the act of breastfeeding, which is also seen as a very private and holy act.
Well, it's hard to say for sure. The concept of 'porn-like' is quite subjective. Some might consider certain novels with excessive sexual descriptions as such, but it depends on individual perspectives and cultural standards.
In many places, 18+ porn comics are considered illegal. This is because they can have a negative impact on society and violate moral and legal standards.
