My step-mom is lacking so instead I’ll use my pleasure to make my step-dad happy – the solution from a loving step-daughter

Of course, a proper wife is one who looks after her husband, so my step-mother does not do this, and therefore, I do. I deepthroat his dick, job done, then I go for a very playful cunilingus with him. Then, I fool him by giving him a crazy ride on the bed, and he is fully sated.
