The Request

I am officially an adult now.
I felt that this day would be different from the others and not just because I turned 18.
My aunt Sonja came over to celebrate this big and important day. She is my mother's younger sister, 5 years apart. She just turned 41, but despite her age, she would still wrap any man around her finger.

My mother and Aunt Sonja would talk in the kitchen for long hours while eating cake. Sometimes they would just watch me and whisper to each other or giggle about something I didn't understand.

It was late at night, I was already pressing the phone in my bed before falling asleep, when my mother unexpectedly came in to see me. "I hope I'm not disturbing you, can we come in?" Sonja was standing behind my mother, leaning against the corner of the door in a white robe. My suspicions were growing. They sat down close together, their hands on each other's knees.

-Son, there's something we'd like to ask of you. It's no small thing, only you can do it.
-What would it be?
Since you turned 18 today, meaning you're a man, you obviously have needs.
-No, let me tell him!
-Sonja, no! I have to tell him, I'm his mother, please, let's do this as we planned!
-You're right, don't be angry, I was impatient.

I sat in my bed confused, looking at them, having no idea what this was all about, until my mother said, her head slightly lowered, "I want you to get Sonja pregnant!"
I almost fell off the bed, but almost out of reality too. I couldn't understand the sentence, even though it wasn't difficult, it wasn't long, but it was still hard for me. My aunt pulled me closer while she put her hand on my leg with big eyes. "Since I don't have children and I don't have a husband to have a baby with, so you were the one I chose, because I love you the most as a man, I want a baby from you!"

I felt dizzy, shocked, and a mixture of all of these. I just looked like an idiot, even though I should have answered. "We won't tell her who the father is, and if she looks like you, we'll make up some lie."
-Son, please do it! Not for me, but for your aunt!

The words were heavy, weighing on my chest like a rock while the blood kept flowing to my cock. Sonja leaned into my face, peering into my eyes. "Just think of this as sex. nothing more, just plain sex!"

-But can you still have children at this age?
-We thought you would ask. Yes, I can get pregnant, the doctor says I can have another child. I should find a sperm donor or find a man in time. And I want you, you are my choice!

Sonja comfortably lowered her robe. Her breasts are still firm, no sagging, the closeness of her skin and her slightly hairy pussy drives me wild, taking away all inhibitions and sober thinking. Her dark brown eyes are as if they can see right through to my soul.
She takes a place on my lap while our lips get to know each other. Our bodies know each other, but not so close and so intimately. We kiss in the soft bedclothes. My cock is alert, like a predator waiting for prey. Her breasts brush my chest as her hands start their journey downward. I'm excited and the fear is reduced, an indescribable instinct takes over that doesn't care about the consequences, not even that my aunt is the one I'm going to fuck. I started kneading, licking and sucking her breasts.
-Ohh, what a good breast sucker you are!
-I hope you're just as good a cock sucker!
-Hey, you can't talk to my sister like that!
-It's okay, let her fulfill her desires, she's a man now, not a little mama's boy!

Sonja's sucking was fantastic. I thought it would be as intense as what I've seen in movies, but it wasn't. Slow, graceful, but still intense and the way she looked at me while doing it. I saw in her eyes the ferocity, fire and desire that was also there in me.
Supposedly you can get a woman pregnant with pre-cum, but I think that wouldn't have been enough for my aunt. I felt her milking me hard, with her mouth and hands, but just enough to fill my pussy. I didn't know how many men she'd been with or what she'd been through before me, or if I'd be enough for her, I just knew I had work to do. Her pussy was wet, ready to receive me. I was selfish and attentive at the same time. I mostly just wanted to satisfy myself, but I didn't want to neglect or miss out on Sonja. It didn't bother me that my mother was watching us on the couch. Anyone would freak out if they caught their sister or brother fucking someone else or a friend, especially if it was a similar, related case. But there was no such example here, because my mother watched us silently, patiently and with interest, I excitedly scraped the edge of the couch.

Sonja's body was large for an average woman. You could feel horizontally that she was slightly bigger than me. Even though she was younger than my mother, who is about 5'6", my aunt was nearly 6 feet tall.”

My lungs and hips were tired, my feet were sore, but I managed to cum and get my seed into her body.
My mind and thoughts returned as I lay dazed next to Sonja who smiled warmly at me and just said "Thank you"
That night we slept together thanks to my mother. I spent the whole night staring out the window wondering what I had done.

The next afternoon Sonja went home. We talked a little, but there was no need for that anymore. More than a week later my aunt called us to say she was pregnant. Should I have been happy? I don't know how I would have reacted to such news.

Now I can see Sonja's growing belly and I keep thinking that she won't be the father of that child, just because I wanted a quick fuck.
