I had planned on just giving my stepson a nice blowjob that morning, but I was getting really turned on. I had actually never been with a virgin before. When he put one hand on my head and pulled me down deep on his cock, and put the other hand up my dress and fingered his mom's pussy, I decided I just had to fuck him! Since I wasn't wearing any panties, I just climbed on top of the boy. I rode him gently since it was his first time and soon I had two back to back orgasms! I then lay on my back and let him enter me again and told him when he was ready I wanted him to cum all over mommy's face, mouth and tits. He had such a hot big load in store for me, his cum just kept spurting out me and on the bed sheets! Of course, I thought it would be a good idea to keep him home from school that day....so glad my stepson is finally 18!
