Sucking My Step Son's Huge Cock

After finding out that my step son was about to go on a date with his new girlfriend, I decided to talk to him about how sexually active they've been. It didn't take much to realize that he was nervous about something. So, figuring that I'm his step mom, I hoped that maybe I could help him open up and break the ice a little about "the sex talk." As I suspected, he was nervous about being able to perform since he's never had so much as a blowjob before. So I did what any good step mother would do and offered to help him out the best way I could think of - by breaking him in and giving him his first blowjob. I had no idea the huge cock that he was packing. But I stuck to my guns and showed him what it felt like to have my lips and tongue teasing his enormous cock. I was surprised how long he lasted considering, but I got a little too carried away and missed how close I was bringing him to cumming until a massive load erupted from his cock all over my face.
