GIGL-773 - Left alone with my friend's hot mom while he's out

I went to my friend's house, but he was gone. Left alone with his gorgeous mom, I couldn't help but get a hard-on. She noticed, licked her lips, and grabbed it, asking if I wanted to do it with her. She told me to keep it a secret from her son, and I ended up losing control and banging her. The third installment of the series.
