Stepmom Jerks off and Sucks Stepson with Broken Arms

I was changing in my bedroom when I caught my stepson watching me from outside the room. We started talking about our bodies and how its natural and okay and he told me about being really frustrated lately. Unfortunately, the poor guy has two broken arms and hasnt been able to release himself. The view of me got him already hard and precumming so I figured I'd help him out. Besides, what are stepmoms for?
