My uncle helped me, so I want to help him

My uncle works for a firm that I have been trying to get a job with for the last year. He was able to get my foot in the door and I got the job of my dreams. He's my stepmom's brother and I have always had a crush on him. I can tell that he thinks I'm sexy too. I see him look at me and he gives me long hugs at family gatherings. I used to love sitting on his lap. Now that I'm all grown up and got this awesome new job I went to his house alone to thank him for helping me. I pulled his cock out and it was so thick and perfect, I had to have it in my mouth. I loved the way he tasted and I could tell he loved me shoving his fat dick to the back of my throat. I got naked and showed him my perfect titties while stroking his cock. I got down on my knees like a good niece and let him rub his cock between my perky boobies. Stroking and pulling he exploded all over my chest and I cleaned him up with my mouth. Thank you Uncle!
