Stepmother jerks off stepson when she bathes him

The boy had an accident recently and his arms are in a cast. The stepmother takes care of the boy with a lot of dedication. The boy needs a bath and the mother offers to help. The woman washes his back and chest, and when she reaches the boy's cock, a little embarrassed, she washes it anyway. She feels the pot react to the contact with her hands and gets horny. She grabs his cock and jerks it off shyly at first, but very horny later
