My wife Julie gave birth to my first son a few days after New Year's. Her widowed mother Violet (Vi for short) would come to our house often for the next several weeks to see how the 3 of us were doing. She especially wanted to make sure Julie would be able to produce enough milk for the baby. She did produce some, but somehow not quite enough. Even after the baby emptied both of Julie's breasts, he would cry for more. So Vi would open her blouse and put the baby to her own breasts to calm him down. The ladies would then bottle-feed the baby some formula to compensate for Julie's scanty milk. This went on for 2 weeks, until one day I heard Vi shout to Julie with excitement.
"Julie, I feel something. I'm lactating!"
"Wow, Mom! Can it be? Now we both can feed the baby from our breasts!"
"Exactly. Now we won't have to worry about formula anymore."
One week after that, Julie went out to shop for new clothes for the baby. But before she could get into the store, she slipped on some ice and broke her leg. That meant she'd be in the hospital for quite some time, so Vi would stay at our place for the duration and breastfeed the baby on her own. One evening I caught her doing so near the kitchen counter, her eyes closed. While she had the baby at one breast, the other one was fully visible to me: large, cream-white, with a dark-pink areola about the size of a 50-cent piece, and a nipple as big as the eraser of a pencil. It didn't take me long to get one of the most intense erections of my life.
Then she opened her eyes and shouted, "Whoops, I didn't know you were standing there!"
"Oh, I'm sorry, Vi. If you want me to leave..."
"Nah, that's OK. You may stay here and watch if you want."
And watch I did. As she guided the baby from one breast to the other, I watched a lock of her dark brown wavy hair billow almost as far down as the top of her breast. Then I stared at the breast at which the baby had fed earlier, and I began to wish I could suck from Vi's ample breasts myself.
Once the baby had had enough, Vi put him in his bassinet to sleep, then said to me, "I see this has gotten you quite excited! In fact, I get aroused too when I do this." She then took her blouse completely off and I took off my own shirt. For a long time we stood topless without saying a further word, with our eyes closed, our arms around each other, and her breasts pressing against my chest.
After we broke our embrace, we went to the living room. My mother-in-law sat on the couch and said, "Come here, honey. Lay your head on my lap." Once I did as she asked, she lifted my head and offered me her left breast. After a few minutes of sucking, I could feel something warm and sweet filling my mouth. It had to be milk. I continued sucking until I could feel that breast drying up. Then Vi guided me to her right breast and I drank more of her sweet milk.
Suddenly I could feel the hardness in my pants intensifying. Before I could say anything to Vi, I shot a huge load of semen into my pants, enough to cause a pool to form on the outside of them.
"That must have been too much for you!" an astounded Vi commented, "But don't let go yet, there's still a little more milk for you to empty." So I continued to suck her right breast for another minute or so, then finally it was empty.
As midnight approached, Vi went back to the kitchen to retrieve the baby's bassinet, then took him upstairs and tucked him into his crib. Then she summoned me up to the bedroom that normally was mine and Julie's.
"Would you mind if I sleep on Julie's side of this bed for the rest of my stay?" Vi asked, "I'd hate for you to be cold and lonesome for many nights straight."
