I was late coming home from my night shift job at the hospital and just missed my husband who had already left for work. Still wearing my naughty nurse uniform, I went to my stepson's room to make sure he was getting ready for school. As I sat beside him on his bed with my 34D cleavage spilling out of my mini uniform, my short little dress exposing my trashy fishnets and garter, I couldn't help but notice he had a morning stiffy! Of course the conversation turned to sex and I learned my 18 yr old stepson had never had a blowjob before. I simply couldn't resist his thick hard cock and took it all the way down my throat as he put his hand under my dress and explored his mom's wet pussy. I was just going to let him cum in my mouth, but I got so excited I decided I had to have his virgin cock inside me first....
