My grandmaother took the lactating pill too

Continues the "I gave my grandma's sister a lactating pill.

In my previous story, i slipped a lactating pill in my grandma's sister drink, making her tits produce milk again, leading to a breastfeeding and sex vacation.

Mary continued to give me tit and i to satisfy her and me also. We where waiting for my grandma to try her tits too. The good news came, my grandma Nina called that she will spend the rest of the summer with us.
So our plan was put in motion. Mary visited the fresh mother and bought two lactating pills saying they are for a distant niece. One was enough for Mary but she said better to be sure.
My grandma arrived. All we had to do was to slip her the pill but theory was one thing, practice was another. My grandma took control of all that ment Kitchen chores and she was stubborn about it, exasperating Mary and me. When all was lost, Mary remembered she had cherry syrup in her basement, the one place my grandma didn't control. So she got down in the cellar, took two cups and put syrup in both, spiking one with the pill. Then she go to my grandma.
- Look Nina what i found! I forgot i had this cherry syrup.
- How old it is? It's ok to drink?
- I'll put soda over both and drink this one. If I don't shit myself in the next 10 minutes, neither should you.
My grandma took the bait and drank the glass, even asked for another, witch Mary spiked with the second pill.
Both Mary and me waited anxiously for the pills to work. And in a few days, my grandma began to massage her boobs more often and to pinch her nipples.
I finished the usual chores and go to the house to relax a little. Looking through the window of my grandma's room, i saw her topless, sitting on al fours and Mary with her hands sunken in her fat, massaging her, grabbing her tits, squeezing them making the milk to spray.
- How come i have milk at this age? What could have happened?
-Well, said Mary, you always wanted to breastfeed your grandson. Maybe you thought about it and you started making milk.
- What nonsense you are speaking? That happened long ago, when he was small. Now he's grown. I cannot do that anymore. And lactating just by thinking about, if it was so easy….
- Well, you must do something with the milk and you tremble when i touch your boobs.
- I always have them sensitive. Let's see how you do when i touch yours.
Grandma quickly slided her hand under Mary's T-shirt and grabbed her tit. It was so fast, she couldn't react. Milk started to fill grandma's hand. She took it out and saw it.
- So, you are lactating too. Did you and Mikey……..? Did you had to do anything with this? pointing at her tit.
Mary spoke no word. My grandma dressed and was trying to gather her thoughts.
- Ok, she said. Let's call the boy and do it.
I quickly got away from the window, pretending i am doing something. Then i heard Mary calling me into the house. I was anxious but i tried to hide it.
Both of them where standing at the edge of the bed, talking this and that. They called me to sit between them.
- Is the gate locked? asked my grandma.
- Yes, it is, i said. Since last night.
- Ok, she said. Mary…
They both lifted their t-shirts at the same time. First i saw Mary's tits, sagging on her belly, her light pink areolas and nipples facing down, like a goat's. Then i saw my grandma's huge engorged udders with big round areolas. Her nipples where hardened from Mary's massage, leaking milk like broken faucets.
I just stood there, looking at one, then another, unable to decide who's tits to suck first. My grandma pulled my head to her, stroking my hair. She lifted her tit and guided my mouth to it. I latched on her huge areola and i felt it was melting like butter in my mouth. She started chuckling as i sucked her milk fat as sour cream then her laugh turned to moaning.
After a while, i switched to her other tit. It didn't need to suck too hard. She was so engorged, milk flown by itself.
I lifted myself to stretch a while. Mary pushed me by the shoulders on the bed. She climbed on me and swayed her tits ove my face, grinding her ass over my erect dick. I pulled down my pants, she lifted her skirt, she sat on my cock, teasing me with her nipples. I took her tit in my mouth and sucked her milk while she impaled herself in my cock. Sucking two pairs of tits and Mary riding me with her pussy hot as an oven was too much for me. My cock bursted inside her, i felt my soul exiting from my body in those spasms. Mary grabbed my grandma's tits and started milking them. Grandma did the same witn Mary's. They grabbed a pot and where milking each other in it. Seing that view simply had me hard again. Mary leaned grandma on her knees, put the pot under her jugs and started milking her like a cow. With each pull and squeeze, milk sprayed with pressure, hitting the pot with sound. My grandma was moaning and breathing deeply. I got behind her, pulled her pants down and pushed my finger inside her pussy. As i did that, she started moaning louder. I put my cock at the entrance and slided in. Her pussy was wet and hot. I started fucking her from behind. Grandma started shaking and for a moment, she couldn't control her muscles. They twitched and tighten the grip on my dick. I fucked her faster and faster until i came too. As soon i was out of her, grandma got on top of me, burried my face betweem her tits and guided her nipples in my mouth. I suckled until there was no milk neither in my grandma's tits nor Mary's.
For the next few months, Mary and my grandma breastfed me and we played under the blanket. I've noticed i became a little chubby from the mommy essence.
When autumn came, we got back in the city. My grandma lived close to me so i visited her daily as she continued breastfeeding me.
Mary stopped lactating. It wasn't worth keeping the supply for nothing. I still drysucked her tits when she visited grandma.
The next year things where more simple. We knew what to do, all the parts where willing from the start and the pill worked on Mary like a charm.
