I have a much younger cute stepsister who is so timid that she can't firmly refuse sexual harassment. Plus, she's totally my type! So I tried to barge in while she was taking a bath and offer to wash her body. Of course, at first she was surprised and refused. But as I gently and thoroughly washed even the hood of her clitoris, she kept saying 'Wait stop' or 'No please,' while moaning extremely lewdly and cumming over and over!
