The nanny's responsiveness in bed probably gave her a reason to get a raise, and then she worked her overtime. The girl is beautiful, with soft forms, in which you want to enter and continue to fuck with pleasure. Not only is she comfortable to get underneath, but she's also comfortable to sit on top of your dick. Plus she's ready to suck and accept cum after sex. All convenience for the money.
I would have fucked this blonde too, if she had spread her legs in front of me on the bed and fully trusted me in different positions.
