Step mother just stopped by and said I will be jerking off for her at her house tonight..

This should be interesting.. I really don't like her.... She comes in her and tells me to jerk off to her as she rubs her tits together, wants me to fantasize about her and tell her the details of what I am fantasizing about her. As she looks at me with this fucking smirk... I tried to play off and cum on her face but she told me to slow down and that I wasn't allowed to cum till tonight, grinning like I was about to cum because she was so fucking hot that I would be so turned on that I have to cum...
