Sitting on my stepson's cock in the living room

My stepson was ignoring his chores and playing video games again. I had asked him to fold his clothes and put them away, and he just wouldn't do it! I had been watching a lot of porn lately though and one thing that I had noticed did seem to work when it came to convincing a stepson to do something; was sex. I could sit on his cock. His dad wasn't home.....and her stepson's cock was a lot harder than her husband's cock anyway....who knows?,maybe it would be fun!
