I managed to do this! I have a window that faces the street but is somewhat quiet. I put a buttplug in since @StraddleOverlord requested it. I edged myself pretty fast, partially because I was doing another edging task before this. So to make it last longer I edged myself in front of the window twice. I hope you don’t mind ;)
Hahaha this would be fun when I’m on vacation or something, but I don’t want my neighbors to see my kinky side! I modified this a little - I sat in front of a window with my top on so it just looked like I’m staring out the window, and used my vibrator.
Honestly, I don’t know if you planned this, but the hardest part of this was getting ready to cum when someone was walking by. It’s not that crowded and people generally didn’t look up, so I was basically keeping myself on edge for a long time. The first time someone walked by and looked up I didn’t manage to cum fast enough, so I had to wait for a second person to come by!
