My step-aunt has been working really hard and she sprained her knee. She had me go to the pharmacy to buy an ace-bandage. When I got back to her house, she had changed into a sexy black slip. I got so embarrassed because I had to hide the erection I was getting….for my step-aunt! She said that it was the only comfortable thing she had to wear, and then she asked me to wrap her knee. When I was wrapping her knee my huge cock slipped out of my pants for her to see. Before I knew it my step-aunt was sucking my cock and begging me to shove my huge dick down her throat.
