Zoe's Other Parent arrives as a surprise.

While Sophie's mothers were currently with Sophie, my family and I were waiting in the lobby. My erection was ready and waiting, but I chose to ignore it, more jumpy and full of stress than horny. I wanted to be there for Sophie, to keep her happy. Hell, I would be the one in there, enduring whatever pain she might feel, but Sophie wanted to be the one to have our first baby.

"Sorry I'm late. I didn't get the memo until I arrived at the house."

I jumped at the sound of that voice. I turned to the source.

"Mother!"

"Happy birthday, Zoe."

I ran to my mother and gave her a big hug.

My mother, my mom's girlfriend, had long black hair that streaked down her shoulder blades. She wore dark-red lipstick and eye-shadow, with a beauty mark on her chin and a pair of glasses that gave her a "sexy librarian" look to her. She wore nothing else but a red-leather skirt held around her waist by a string.

When people saw me with my mother, you would not be able to tell that we were related, the majority of my features coming from my birth mother (that is, the mother that gave birth to me). My parents were not married, which was a common thing in this society. Marriage went out of style for most, people simply being content with just being there for each other. People would have sex with multiple partners regardless of dedication, whole families established in a polyamorous household, hence why Heather and I had different mothers but the same mom.

"Mother, what are you doing here?"

"Well, I was going to be there for you when you came home from school to celebrate my little girl's birthday. But when I got there, I found the house locked and empty. Then your mom called me and told me what happened. I guess 'happy birthday' will carry all new meaning, right?"

My brain freezed up again, having gone back to the present situation.

"Hey, hey," mother said, placing her hands on my cheeks. "It's going to be alright. Sophie will be just fine and you'll be the proudest momma in the world. I just know it."

I blushed and smiled, confidence swelling in my bosom. Mother kissing me deeply, leaving lipstick on my lips.

"Now until then, why don't we take care of this?" She asked, placing her hand on the head of my cock.
