I must have sat there staring at her juicy tits for longer than normal because I heard Pam clear her throat. I was jolted out of my stupor and reached clumsily for the pump that still sat in my lap, hoping she wouldn’t notice the raging hard on in my pants. I opened the bag and pulled out the contraption.
“How do I…?”
“Well, first it would help a bit if you would massage the breast,” she said, seeming a little less hesitant than she was before. “Helps to get the milk out… it’s called letdown.”
If there was anything this situation was, it was most certainly not a letdown. I nodded my head and reached out my hands, placing them both on my stepmother’s tit. The skin was soft under my palm, and as I squeezed I could feel her flesh mold to fit the shape of my hand. I couldn’t believe I was touching them… my cock throbbed with every grasp of my hand.
“Okay, that should be good,” she said, and I was disappointed, but I moved my hands and picked up the pump anyway.
“Now, if you would guide the breast into the pump… make sure the nipple is placed properly…”
I held her breast in one of my hands, picking up the pump with the other, and placing the funnel shaped end squarely on her nipple. Once I felt that it was a snug fit, I wrapped my fingers around the handle and squeezed.
The first few times only a few drops of thin white liquid came out; and then a sudden stream of milk came squirting out of her nipple, running in tiny rivulets down the sides of the container, forming a small puddle at the bottom. I squeezed again, sending another shot of milk into the flask. I kept pumping, mesmerized at the way her nipple was sucked and elongated with each clench of the handle.
We sat there for a few minutes, me pumping away and Pamela not saying anything. At one point I looked up to see her face, and I noticed that her eyes were staring rather fixedly at my crotch. I blushed and looked down, hoping my excitement wasn’t too apparent, and resolved not to look at her face again until this ordeal was over. (Probably not even afterwards…)
After a while she had me switch to her other breast, which I also had to massage before placing the nipple into the flask and pumping away at her breast. The bottle was half full by the time we made the switch, and would be completely filled to the brim by the time we emptied her second breast. My cock was straining painfully against the fabric of my shorts — I felt like I was going to explode any second. This was too unreal; I could not believe that I had sat here pumping my stepmother’s breasts…
Eventually we were finished. I removed the pump from her breast and tucked her tits back into her bra, pulling her shirt up and removing them from my sight. She raised her palms and rubbed them lightly over her chest.
“Oh, Paul, you don’t know how good that feels… So much better! Thanks, hon!” She smiled brightly at me and had me cap the bottle and place it in the refrigerator for her. I bagged the pump and threw it on the counter, mumbling a “You’re welcome” to her before rushing out of the kitchen, making my way as fast as I could upstairs to offer my aching cock some relief.
