My GILF tutor got scared and tried to get away, but it was obvious that she got very horny...

I had an art history exam coming soon, so I found a tutor who could help prepare for it. When we started our lesson, she told me that I could do better if I try to paint something myself. I had a white piece of paper and a few marker pens in front of me, but all I could think of was sex. My tutor was pretty mature, yet a very sexy woman, and I would surely love to draw something on her back with nothing else but my cum. I took a marker pen and wrote “FUCK HERE ->” on her leg, with an arrow pointing to her pussy. She got scared and tried to get away, but it was obvious that she got very horny, and deep inside she really liked what was going on. She spread her legs with obedience allowing me to create my live sex masterpiece.
