My Step-MOM Starts to Embrace Our Sexual Favors for Chores Deal

Description: So.. as the months progress, i have held up my end of the bargain everything has been going extremely great. one night as we finish up dinner and i so kindly offers to take my empty dish and do the dishes (without being asked) but then i then awkwardly approach her with a question. i am still a bit nervous about her reaction when i asked to cum in her face a few months ago and so she has to coax the question out of me. what i really want, now, is to push things a little further and start getting blowjobs from mommy. at first she is way against it, however, she makes me a deal that requires even more responsibility. i have to not only get a job, keep up with all of the chores, but keep it for at least 3 months. after that, i can have a blowjob. it turns out, to her surprise, i am committed, i keep the job, get my blowjob and we agree that as long as i keep it that i can have one a month. after months of this, while she is giving me my blowjob she finally asks me why i haven't tried to press me to have sex yet. at first i act apprehensive, and it puts her in the position of begging. which, in the end she does, we re-negotiate another deal that allows me to have full control of how often, what positions, and where i want to cum. my step-mom wants it so bad at this point she stops mid-blowjob and i lets me fuck her for the first time. i, of course, having now full control, to cum all over her face. negotiation, success.
