My step-sibling impregnated me during the festive season

The festive season is always a special time of the year, especially when you're 18 years old and pregnant. My step-sibling, who is not my real brother, decided to give me a special gift - his big cock. He was more than happy to see me on my birthday, and he couldn't wait to get his hands on my tight pussy. After a steamy blowjob, he plunged his big cock deep into my wet pussy, stretching it to its limits. The feeling was intense, and I could feel every inch of his cock inside me. He fucked me hard, pounding my pussy with his big cock, making me moan with pleasure. The sight of his cum filling my pussy was a sight to behold, and I knew that this was a gift I would never forget. This is the story of how my step-sibling gave me the best birthday present ever - his big cock and his cum.
