It was the weekend, David tinkering outside while Mum lay on the sofa with an old photo album on her tummy. At 40 weeks pregnant, she could give birth at any moment. She was wearing a loose black dress that went down to her pretty bare feet. I was torn between two feelings. I was excited to have my little sister in the house, to be able to watch her grow up and be her big brother. But I was also sad, when mum is not pregnant anymore, the energy we both created will surely decrease. We might have sex less often, I might not be able to cum inside her like I did the last few months.
I went to join Mom on the couch.
"What are you looking at?"
"Some pictures from high school and college, look," she said, making room for me to sit next to her and look at the album. The first picture showed my mum in high school no doubt, dressed as a cheerleader, and all I could say was that she was really hot.
"Wow, you were really hot!"
"What do you mean I was?" she said with a frown.
"I mean, you still are, but very different," I said, putting my hand on her baby orb.
"Wait, look." she turned the page and showed me a picture she'd taken in college, from what I could tell by the roundness of her stomach at graduation.
"Is that me?" I said, pointing to her plump figure in the photo.
"Of course, when I got my degree, I was eight months pregnant," she rested her head against my shoulders. "It was a complicated time, your father had left me, your grandparents were not at all happy that I had a baby on my own at 21, and on top of that I was working at dinner and in my condition, it was difficult."
"You made up for it." I gave her a big kiss on the cheek as I hugged her. "You are the most wonderful mother in the world.
"Stop complimenting me Thomas" she said with a smile "you're only saying that because you're a young rascal who can make love to his little mummy."
It was true that my special relationship with my mother made her even more important in my life, but even if nothing had happened between us, she would still be the most important woman in my life.
"No, you know I love you, no matter what happens or what happens."
My mother sat up on the couch and gently kissed me on the mouth. Her soft lips against mine, her delicious perfection brushing my nostrils, and her tongue curling with mine. David may have been not far outside, but I wanted to make love to this woman before she gave birth. "Mom, I know this isn't the time, but I want to..."
"Don't say anything, go up to your room, David is far too busy to worry about anything" I loved it when my mother took the lead like that. She led me by the hand into my room and locked the door while I undressed.
I was now naked, standing in front of my fabulous mother, who let her dress fall to her feet, revealing her entire body to me. She approached me. Her huge belly was perfectly round, she had no stretch marks but simply a nice brown line running down her belly through her navel. Her big milk-filled breasts had never been so big, and with the baby coming soon they had grown even bigger. We embraced in a long loving kiss, feeling our bodies warm against each other, my cock erect against her bulging belly, her slightly pale skin was so soft.
"Still excited about your old pregnant mum?" she said, stroking my face.
I nodded. She tackled me wildly on the bed and straddled me within seconds, her long legs going on either side of my pelvis, I could feel the groove of her pussy around my cock. She leaned over me as best she could to kiss me. Her belly was all squished between the two of us and the feel of it was very nice, there was an inch of soft elastic flesh before it was stopped by something very hard, where the baby lay. Mum straddled me like this, while inserting my sex into her pussy. As she rode me like an Amazon, I placed my hands on her plump buttocks, she leaning on my torso with her arms stretched.
My mother let out small sounds of pleasure, but remained silent so as not to risk revealing our incestuous relationship to my stepfather. Before I came, I wanted to change my position. I put her on all fours, she leaned on her forearms while I pistol-whipped her big tight pussy, holding her waist with my hands. Even her back was beautiful, that of a mature woman, with the marks of age but I didn't care, she was my mother! pregnant and sexy and I was fucking her, her long brown hair slightly curled and falling on either side of her arched back and her round belly bouncing with each thrust of my cock inside her.
I couldn't take it anymore, I pulled out of her. "Mom, I want to look you in the eye."
My mother turned and lay on her back, looking at me with her soft motherly eyes.
I lay on top of her, feeling the shape of her baby bump against me and her huge milk tank against my pecs. She wrapped her long, shapely legs and arms around me. I began to fuck the spot where I was born 19 years ago and where my sister will be born in a few days, feeling my cock touching deep into my mother's birth canal.
"Oh, Thomas, darling, you make me feel so good," my mother said in a trembling voice, a tear running down her cheek.
"I love you mum, I will always love you, I want you to be my wife."
