My semi incestuous relationship with my grandmother

Guys I can suck her boobs anytime I want. It’s because of an incident. I don’t know exactly my age but it must be 6 or 5. Once in public I saw a mother breastfeeding her child.
M : Grandma what is she doing???
G : she is giving milk to her child.
M: but why can’t she buy milk from shop.
G : little kids should drink their mother milk them only they can be healthy.
M: did I drink from my mother??
G : (with tears in her eyes)no beta your mother left this world in your first month so you drank only little milk from your mother.
M : why didn’t you give me milk grandmother??? You could have given know!!!
G : I’m old so I don’t have milk beta
M : you are lying you have big chest(breast) I see daily your chest(breast) you cheated me without giving milk
Saying this I started crying
G : first it’s not chest it’s breast and OK I will give you my breast but there is no milk in it you should not again crying for milk
Since I didn’t believe her that time I asked her to give her breast there itself.
M:okay I will check milk is there are not now give me your breast
G : here no!!! I will not. Once we get home I will.
During that time a person came and asked why was I crying and my grandmother said that he wants milk so only he is crying. That person gave me a chocolate I don’t know why did he had one but I got it and told grandma I will get milk once we get home. At home
M : Grandma milk!!!!
G :wait da I will after five minutes
She came after five minutes and opened her blouse.
G : don’t bite just suck them you will know there is no milk.
M:let’s see
I was sucking for 2 or 3 min but no milk came I got angry so bit the boobs
G :why are you biting da????
M : there is no milk that’s why???
G : I told know there will be no milk you wouldn’t listen!!!!
But I was sucking Eventhough it was empty
G : there is no milk. Why are you sucking eventhen???
M : Grandma I like your breast. I just want to suck them daily can I??
G : but there won’t be any milk and why you want to suck my breasts daily???
M: I didn’t get to suck my mother’s breast for milk. You are my mother now. So I want to suck it to make me feel as you are my mother
She got tears and deeply kissed me on my lips showing her love and affection and said
G : you can suck your mother’s breast anytime you want anywhere you want you can have it
And hugged of tightly with tears in her eyes and me too hugged her tightly with her nipples in my mouth.
From that day on she used to give her boobs whenever I want. Before going to school I used to suck for 10 min and after from school 10 or 20 min. Daily I would suck her. But the time got reduced once I joined college but I still continue to suck her. One time when we were traveling in bus I wanted to suck she thought for a while and opened her blouse placing her sari over my head and I started to suck. Some saw us and didn’t say anything. I just sucked for two min and left because some eyes were on us. That incident made me to suck my grandmother’s boobs for my whole life.
