It just happened again I'm off on a weekday for once with nobody else home. So, I got completely naked, turned on some porn and started masturbating. I had the shower on and the porn was pretty loud so when I looked up and saw my nieghbor staring at my fully erect penis I was surprised. I guess she comes over to feed the dog, which I didn't know, and caught me red handed. The thing that got me was the look on her face. My cock exploded, it kept spasming longer than at any time in my life. She watched every squirt. I came so hard my cock actually hurt. Thank you Debbie
