Aunt's Need

My Aunt, 34, was widowed 2 years earlier, and she had no children. Very well off financially, she wanted at least one child, maybe more, and did not want to find another husband, as she already had too many money-hungry men trying to marry her. I'm her only nephew and had just finished college, just passing at the bottom of my class. No real great future career on offer. But my aunt hired me as her chauffeur/bodyguard; I'm quite good at the martial arts. A lot better than my college score on other subjects suggests. I've a solid physique and am tall at 6'3". My presence usually deters would-be suitors from approaching my aunt. Of course, being with my aunt almost all the time meant we became lovers, which led to her getting pregnant by me, by her decision. My job changed slightly with the addition of a childminder to my duties. Usually, just when she is attending meetings, I do sleep with her every night; perfect job for me.
