It was our first Father's Day after we got married. I woke up as my wife sucked my cock, and I instantly became hard. Once she noticed I was awake she sat up, showing her naked body: beautiful full breasts with hard nipples, a nice flat stomach and as a surprise a naked pussy. Her hands were rubbing her tummy.
“I want you to become a father, I want you to make me a baby in my tummy,” she whispered. “I stopped the pill some time ago, and this should be my fertile period. So for the first time I want you to fill me with your cum and not fill a condom."
She climbed on top of me, and grabbed my naked, hard dick and inserted it in her soaking pussy.
It just took a little while for me to cum, and the moment I filled her pussy she also came. It was the first time we had sex without protection. That day, I filled her up a couple of times more, and we did not use any condoms from that day on.
Just over nine months later, I really became a dad.
