I caught my stepson jerking off with my panties

After a long hard day at the office all I want to do is relax. But as soon as I walked into my bedroom this evening I was shocked by the sight of my stepson jacking off with a pair of my panties (dirty ones straight out of the laundry hamper). I begin to scold him, then I decide to have a bit of fun with him. I tell him to keep doing what he is doing. Then I start to strip off my clothes. Taking off my panties and picking up a dildo I begin to rub my panties on the dildo before licking and sucking it. Finally satisfied that I've teased him enough I lay back on the bed and invite him to fuck stepmommy. (Sex simulated with dildo).
